3 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4 Warn about $@ not persisting. Problem reported by Julien Danjou in
5 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
7 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
9 * doc/autoconf.texi: Some systematic minor improvements, as
10 follows. Use "makefile" when talking about makefiles
11 generally (which might be named "makefile" or "Makefile" or even
12 "foo.mk"), "Makefile" when talking about a specific makefile
13 called "Makefile". This unclutters the text from weird quotes
14 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
15 values" rather than "@var{foo}s" and similar constructs containing
16 "}s". Use "Make rules" rather than "Makefile rules". Minor
17 English-language improvements. Change the prefix "sub-" to "sub"
18 and "re-" to "re".
19 Put blank lines around examples more consistently.
20 Avoid "rather" and "very" as intensifiers.
21 Avoid "will" as an auxiliary.
22 (Limitations of Make): Split this node into....
23 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
24 (Leading _ in Macro Names, Backslash-Newline-Newline):
25 (Backslash-Newline Comments, Long Lines in Makefiles):
26 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
27 (obj/ and Make, make -k Status, VPATH and Make):
28 (VPATH and Double-colon, $< in Explicit Rules):
29 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
30 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
31 New nodes, resulting from splitup of Limitations of Make.
32 All cross-references changed. Raise the top node from
33 a section to a chapter, and all subnodes accordingly.
34 Redo the introductory wording to match the new organization.
35 (Installation Directory Variables): Use an example that is
36 closer to what Autoconf actually does. Mention that VPATH's
37 value should not contain metacharacters or white space.
38 (Fortran Compiler): Fix a VPATH bug in an example.
39 (Leading _ in Macro Names): Mention that this problem is no longer
40 of practical concern.
41 (VPATH and Make): Reword the advice to make it clearer
42 that Autoconf and Automake support VPATH in non-GNU make, but
43 many packages have bugs in this area.
44 ($< in Explicit Rules): Refer to Build Directories rather
45 than using a (non-VPATH-safe) example.
46 (Automatic Rule Rewriting): Mention the sort of disaster that
47 can ensue with Solaris-style rule rewriting with VPATH.
49 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
51 * doc/install.texi (Compilers and Options): Weaken the
52 suggestion to use GNU make for VPATH builds.
54 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
55 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.

58 in regular expression.
60 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
62 * doc/autoconf.texi (Installation Directory Variables):
63 Drop extra @samp from `@table @samp' item.
64 (Limitations of Usual Tools): Comment fix.
65 Do not nest @samp just to point to other table items.
66 (Writing testsuite.at) <AT_CHECK>: The second argument to
67 `@dvar' is already @samp'ed.
68 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
69 do not use @var in the second argument.
71 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
73 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
74 $as_shell.exe too. Problem reported by Andreas Buening in
75 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
77 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
79 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
80 `unused variable' compiler warning, for `-Wall -Werror'.
81 Reported by Jaap Haitsma in
82 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
84 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
86 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
87 case the compiler dumps core. Problem reported for
88 OpenServer 5.0.7 by Tim Rice in
89 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
90 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
91 Likewise.
93 2006-06-06 Tim Rice <tim@multitalents.net>.
95 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
96 "ERROR" only shows up in "make check" output if there is an
97 error.
99 2006-06-06 Eric Blake <ebb9@byu.net>
101 * tests/tools.at (automatically allowed tokens): Fix typo.
103 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
105 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
107 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
108 typically overflows on x86 CPUs, even though the C standard
109 requires otherwise.
111 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
113 * configure.ac (AC_INIT): Bump to 2.59e.
114 * NEWS: Update.

118 Version 2.59d.
120 * config/texinfo.tex: Sync from upstream.
122 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
123 seen, invoke libtoolize with `--ltdl' argument.
124 * lib/autom4te.in (Autoreconf-preselections): Adjust.
125 * NEWS: Update.
126 Suggested by Eric Blake.
128 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
130 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
131 reported by Ralf Wildenhues.
132 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
134 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
136 * THANKS: Update.
138 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

147 * tests/base.at: Check AC_REQUIRE's error message.
148 * tests/local.at (AT_CHECK_M4): New macro, almost identical
149 to...
150 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
151 AT_CHECK_M4.
152 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
153 `expout' as the last parameter.
154 * tests/tools.at: Adapt to the above change.
156 2006-06-04 Stepan Kasal <kasal@ucw.cz>
158 * doc/autoconf.texi (Limitations of Usual Tools): Correct
159 information about race-free implementations of mkdir.
161 2006-06-04 Eric Blake <ebb9@byu.net>

164 * bin/autoconf.as (Usage): Likewise.
165 * bin/autom4te.in (help): Likewise.
166 * doc/autoconf.texi (autom4te Invocation): Likewise.
168 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
170 * NEWS: GNU make now recommended for VPATH builds.
171 Mention that some macros are now documented to be obsolescent.
172 * doc/autoconf.texi:
173 Prefer "current" to "modern" to describe
174 currently-used (albeit perhaps old-fashioned) hosts.
175 Mention which ancient features no longer need to be worried about.
176 setgid -> set-group-ID
177 setuid -> set-user-ID (these are the Posix terms)
178 Fix some misuses of "only".
179 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
180 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
181 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
182 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
183 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
184 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
185 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
186 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
187 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
188 Mention that these macros are obsolescent.
189 (Installation Directory Variables): shall -> should
190 (File Descriptors): Mention that 0, 1, 2 might get reopened.
191 Mention that it's now safe to use 3 and 4.
192 (Limitations of Usual Tools): cp -r is now specified by Posix.
193 Omit longwinded and obsolescent discussion of cp -f.
194 Modernize discussion of expr, ls.
195 (Limitations of Make): Modernize discussion of VPATH builds.
196 Mention $? as a workaround in some cases.
197 * doc/install.texi (Basic Installation):
198 Mention "./configure; make; make install" first. Be more
199 specific about why this file is generic. Remove unnecessary
200 parens. Remove misleading "only". Remove obsolete advice
201 about csh. Don't say "configure" takes awhile; say it
202 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
203 and CC=c99 rather than CC=c89, as these are blessed by current
204 Posix. Recommend GNU make if doing a VPATH build.
206 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
208 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
209 examples involving shell prompts.
211 2006-06-02 Stepan Kasal <kasal@ucw.cz>
212 and Paul Eggert <eggert@cs.ucla.edu>
214 * doc/autoconf.texi (Here-Documents): Add details about the
215 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
216 use "here-documents" instead of "here documents".
218 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
220 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
222 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
224 * doc/autoconf.texi (File System Conventions): Warn about ":"
225 anywhere in directory names.
227 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
229 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
230 about quoting the case statement, just in case.
231 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
232 was fixed in ksh93g; reported by Ralf Wildenhues.
234 2006-05-31 Stepan Kasal <kasal@ucw.cz>
236 * doc/autoconf.texi (System Services): Do not document
237 overriding EXEEXT via ac_cv_exeext=ext.
238 (Particular Programs) <AC_PROG_MKDIR_P>:
239 Document that ${MKDIR_P} understands --.
240 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
241 comment.
243 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
245 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
246 argument with leading hyphen. Problem reported by Paul Eggert.
248 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
250 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
251 about quoting ac_try: quote all of it, if any of it seems suspicious.
252 This means we don't have to worry about ${ or sed any more.
253 Also, double-quote the case statement, to work around misuses via
254 underquoting as reported by Ralf Wildenhues in
255 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
256 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
257 undocumented and dangerous macro.
258 Problem reported by Ralf Wildenhues in
259 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
261 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
263 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
264 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
265 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
267 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
269 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
270 since evidently some packages rely on the old, broken behavior.
271 Problem reported by Ralf Wildenhues in
272 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
273 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
274 pre-2006-05-26 definitions, but leave in the comments that
275 these macros are dangerous and should not be used.
276 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
277 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
278 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
279 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
280 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
282 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
284 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
285 the use of 'tr', since this is our only use of 'tr'.
287 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
288 and Paul Eggert <eggert@cs.ucla.edu>
290 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
291 Don't assume 'grep' works on long lines, since AIX grep doesn't.
293 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
295 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
296 the output file in the `${datarootdir}' test.
298 2005-05-28 Stepan Kasal <kasal@ucw.cz>
299 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
301 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
302 mention of `datarootdir' in the input file(s), but literal
303 `${datarootdir}' in the output file, and we haven't warned yet,
304 then warn as well: the user may have (erroneously) used
305 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
306 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
307 * tests/torture.at (datarootdir workaround): Extend this test.
308 * NEWS: Update.
310 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
311 and Paul Eggert <eggert@cs.ucla.edu>
313 * doc/autoconf.texi (autoheader Invocation): The first argument to
314 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
315 alternatives and clear up the language a bit.
317 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
319 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
320 ac_config_guess, ac_config_sub, ac_configure.
321 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
322 Fix typo that prevented an unnecessary space from being removed.
323 Problems reported by Ralf Wildenhues in:
324 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
326 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
328 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
329 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
330 Don't use the term "thread-safe" to talk about mkdir race
331 conditions, since the problem is more a process than a thread
332 issue. Problem reported by Stepan Kasal in:
333 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
334 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
335 the test for 'install' more closely. Look at MKDIR_P first.
336 Look in the PATH, and at /opt/sfw/bin.
337 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
338 Don't bother to try mkdir -p, since we already check mkdir --version;
339 just look at the version number. (There's no easy way to check
340 for race-free implementations.)
341 * tests/tools.at (autoconf: subdirectories): Adjust to above
342 changes, since MKDIR_P now might end in "/mkdir -p".
344 * doc/autoconf.texi (autoheader Invocation): Mention that the
345 first arg of AC_DEFINE_UNQUOTED must be a literal.
346 Problem reported by Ben Pfaff in
347 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
349 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
350 * doc/autoconf.texi (Special Chars in Variables): New section.
351 (Preset Output Variables): Warn about special chars in CPPFLAGS.
352 (Installation Directory Variables): Quote $(datadir) better.
353 (Limitations of Builtins): Describe some of eval's trickiness.
355 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
356 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
357 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
358 in front of every arg, not just trailing args. Quote apostrophes.
359 (_AC_EVAL_ECHO): New macro.
360 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
361 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
362 removed.
363 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
364 exposed by quoting of eval argument. Put the command on line line
365 so it logs better.
366 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
367 (_AC_PATH_X, AC_PATH_X): Quote more safely.
368 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
369 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
370 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
371 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
372 Use eval more safely.
373 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
374 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
375 to be replaced.
376 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
377 lines, exposed by quoting of eval argument.
379 2006-05-26 Stepan Kasal <kasal@ucw.cz>
380 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
382 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
383 initialization of `ac_cv_exeext', do not override it if it was
384 already set, unless it was set to `no', for compatibility with
385 Autoconf-2.13, and comment this.
386 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
387 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
388 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
389 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
390 Document that this test may be overridden by setting
391 `ac_cv_exeext'.
393 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
395 Revert these two patches:
397 2006-04-06 Eric Blake <ebb9@byu.net>
398 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
399 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
400 2006-04-01.
402 2006-04-01 Stepan Kasal <kasal@ucw.cz>
403 Clean up _AC_COMPILER_EXEEXT* macros.
404 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
405 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
406 ac_file to the name of the default output file and call
407 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
408 initial `rm' of the candidate files...
409 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
410 the same list in subsequent `rm' calls, and for the temporary
411 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
412 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
413 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
414 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
415 no longer needed) by libtool. Make it a cache check.
416 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
417 copied here by mistake.
418 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
419 _AC_COMPILER_EXEEXT.
420 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
421 _AC_COMPILER_OBJEXT directly.
422 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
424 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
426 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
427 Fix description of how the buggy `sed' works.
429 2006-05-25 Noah Misch <noah@cs.caltech.edu>
431 Sync from Automake:
433 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
434 ENOLCK. Only mention `make -j' when applicable. Only raise
435 fatal errors when `make -j' is involved. Improve error message.
437 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
439 * doc/autoconf.texi (Here-Documents): We now know more about
440 the variable expansion in here documents bug.
441 Thanks to Tim Rice and Stepan Kasal.
443 * doc/autoconf.texi (Making testsuite Scripts): Add an example
444 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
446 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
448 * tests/autotest.at (Multiline command from M4 expansion):
449 No failure to be expected if the shell quotes newlines in
450 commands in the `set -x' output. Report by Tim Rice.
451 * THANKS: Update.
453 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
455 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
456 expansion in the here-documents used by config.status, as that
457 runs afoul of the Korn shell version M-12/28/93d bug described in
458 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
459 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
460 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
462 2006-05-23 Jim Meyering <jim@meyering.net>
464 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
465 Fix typo introduced with 2006-04-02 change. It reversed the sense
466 of the test.
468 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
470 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
471 ac_dB slightly, to save bytes in the script.
472 Max out at 50 lines, rather than 96; this is more likely
473 (though not guaranteed) to avoid obscure 'sed' failures.
475 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
477 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
478 `tr -d -' as bad option argument. Work around this by deleting
479 an unrelated character.
480 Report by Tim Rice <tim@multitalents.net>.
482 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
483 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
484 Stepan Kasal <kasal@ucw.cz>
486 * doc/autoconf.texi (Particular Programs): Do not promise that
487 we always prefer the GNU version of the program, and that we
488 search according to PATH; both rules can have exceptions.
489 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
490 AC_PROG_SED. Move descriptions of limitations
491 to the Limitations of Usual Tools section.
492 (Limitations of Usual Tools) <sed>: Mention script length
493 limitations with Solaris /usr/ucb/sed.
494 <grep>: Fix wording for empty alternative. Mention that -c and
495 -l should not be combined, and that -E and -F should not be
496 combined.
498 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
499 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
501 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
502 limits in Solaris 8 /usr/ucb/sed by testing a long script.
504 2006-05-22 Stepan Kasal <kasal@ucw.cz>
506 * doc/autoconf.texi (Defining Symbols): Literal parameter of
507 AC_DEFINE is now passed to m4_pattern_allow.
508 * NEWS: Mention that; likewise for AC_SUBST.
509 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
510 the parameter to m4_pattern_allow.
511 * tests/tools.at: Add a check for that.
513 2006-05-22 Stepan Kasal <kasal@ucw.cz>
515 * lib/autoconf/status.m4: Fix typos.
517 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
519 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
520 only the files that this macro generates.
522 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
524 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
525 the HP-UX sed limitation of 99 commands, labels do not count.
526 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
527 in the comment.
528 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
530 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
532 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
533 Import the following fix from coreutils:
535 2006-01-13 Jim Meyering <jim@meyering.net>
537 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
538 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
539 not double-quote uses of that variable, to accommodate the rare
540 case in which getmntent is available in none of the libraries
541 checked. This happens at least on FreeBSD 5.0.
543 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
545 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
546 ac_config_guess, ac_config_sub, and ac_configure, since evidently
547 some other programs unwisely rely on these undocumented vars.
548 But put in warning comments about them.
549 Problem reported by Ralf Wildenhues in
550 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
551 * NEWS: Document that these variables are intended to go away.
553 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
555 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
556 and set the language to C++ (analogous to the equivalent Fortran
557 tests).
559 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
560 * doc/autoconf.texi (C++ Compiler): Document it.
561 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
562 * NEWS: Update.
564 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
566 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
567 that caused config.status to generate 100-command sed scripts; the
568 portable limit is 99.
570 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
572 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
573 variable `ac_d' instead of `d' to avoid infringing namespace.
574 Report by Ralf Menzel.
576 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
578 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
579 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
580 * tests/tools.at (autoconf: subdirectories): New test, taken from
581 the corresponding problem report by Ralf Wildenhues in:
582 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
584 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
585 Quote some uses of shell variables if they might suffer unexpected
586 globbing. This doesn't fix all instances of quoting problems that
587 I found, just the easy ones that look safe.
588 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
589 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
590 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
591 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
592 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
593 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
594 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
595 Likewise.
596 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
597 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
599 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
601 * bin/autoreconf.in ($help): Reword according to the manual.
602 Suggested by Olly Betts.
604 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
605 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
607 * bin/autoreconf.in: Pass the directory argument to
608 `require_configure_ac'. Fix comment.
609 * tests/torture.at (Configuring subdirectories): Expose this.
610 Reported by Olly Betts.
612 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
614 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
615 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
616 Automake as follows:
618 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
619 `$configure_in' instead of `configure.in', to preserve
620 directory component.
622 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
624 * config/config.guess, config/config.sub, config/texinfo.tex,
625 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
627 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
629 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
630 test for C99 conformance; (bool) 0.5 is an integer constant
631 expression, but (bool) -0.5 is not. Problem reported by Fedor
632 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
634 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
636 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
637 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
638 Warn about obsolete install-sh files. Remove stray sentence
639 fragment and fix cross reference.
640 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
641 install -d; this undoes the 2006-05-10 change.
642 (MKDIR_P): Mark with AN_MAKEVAR.
643 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
644 that we don't require $INSTALL to be thread-safe. Move comments
645 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
646 of AC_PROG_INSTALL. Output a message saying that we're checking
647 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
648 MKDIR_P instead of AC_SUBST.
649 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
650 Special magic for MKDIR_P, too.
651 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
652 a dnl.
653 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
655 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
657 Sync from Automake, as follows:
659 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
660 * config/install-sh: Initialize IFS, so field splitting isn't
661 turned off later.
662 * config/mkinstalldirs: Likewise.
663 * config/missing: Remove superfluous quotes. Replace all uses of
664 `[' by `test', for consistency, and for..
665 * config/missing (sed_minuso, sed_output): New variables.
666 (autom4te, help2man, makeinfo): Use them. Unifies detection of
667 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
668 Fixes `missing' to detect `--output' for help2man. Fixes
669 PR automake/483. Report by Dennis J. Linse.
670 (autom4te): Document in `missing --help'.
672 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
674 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
675 * config/install-sh: Don't use 'path' to talk about file names,
676 as per GNU coding standards. Close a race condition reported by Ralf
677 Wildenhues and Stepan Kasal. There is still a race condition
678 on hosts that predate Posix 1003.1-1992, but we can't help this.
679 Don't mishandle weird characters like space on pre-Posix hosts.
680 Invoke mkdir at most once per dir arg on pre-Posix hosts.
681 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
682 AC_PROG_MKDIR_P from AS_MKDIR_P.
683 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
684 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
685 earlier editions are not (including Automake 1.8.3).
686 Do not suggest mkinstalldirs for thread-safety.
687 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
688 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
689 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
690 presence of special characters and race conditions.
691 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
692 in Autoconf's name space.
694 2006-05-10 Bruno Haible <bruno@clisp.org>
695 and Paul Eggert <eggert@cs.ucla.edu>
697 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
698 from Automake with minor changes.
699 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
701 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
703 * config/install-sh: Update to Automake CVS version, as follows:
704 2006-04-25 Stepan Kasal <kasal@ucw.cz>
705 * lib/install-sh: Simplify the expr implementation of dirname.
706 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
707 * lib/install-sh: Handle --, and diagnose unknown options.
709 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
711 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
712 `./autom4te' to create `./testsuite', since the `all' target
713 will ensure its presence, but `installcheck' should not create
714 the uninstalled wrappers.
716 * tests/torture.at (Unusual Automake input files): Skip if we
717 detect automake < 1.8.
719 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
721 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
722 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
723 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
724 * NEWS: Update.
726 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
728 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
729 munge (multiple) white space and other oddities.
730 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
731 single quotes in variable assignment.
732 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
733 and similar failures by adding multiple spaces, tabs, and other
734 special characters.
735 Report and different test suggested by Francesco Romani
736 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
738 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
739 single quotes, we only need to search for single quotes; this
740 both simplifies the search pattern, and makes us less
741 susceptible to `echo' variations for arguments not containing
742 single quotes.
743 (_AC_ARG_VAR_VALIDATE): Likewise.
745 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
747 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
748 `$*' and IFS concatenation issue with traditional shells and
749 bash-2.04. Report by Seanster@Seanster.com.
751 2006-05-03 Bruno Haible <bruno@clisp.org>
753 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
754 precisely which Mac OS X versions have the od problem.
756 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
758 * doc/autoconf.texi: Use @option systematically.
759 (Integer Overflow):
761 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
762 and Bruno Haible <bruno@clisp.org>
764 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
765 about 'od'.
766 (Integer Overflow): Mention the special case of integer division
767 overflow.
769 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
771 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
772 traditional shells like the Solaris one that do not use the
773 first IFS character for assembling `$*'.
774 Prompted by a related report from autoconf_bug@nro.ca.
776 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
777 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
779 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
780 Mention more problems with the -e option.
782 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
784 * NEWS: Typo.
785 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
787 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
788 in URLs to improve DVI formatted output (requires texinfo 4.6).
789 (System Services, Systemology, Shellology): Likewise.
790 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
791 output.
793 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
794 continuous text.
795 (Runtime): Fix macro argument names to match description:
796 `action-if-found' -> `action-if-true' and similarly.
797 (Obsolete Macros): Likewise.
798 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
799 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
800 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
802 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
804 * doc/autoconf.texi (Limitations of Make): Clean up markup.
806 * ChangeLog: Typo.
807 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
808 DVI output.
810 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
812 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
813 /bin/sh set unsorted output.
814 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
815 * tests/local.at: Likewise.
817 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
819 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
820 (Integer Overflow, Null Pointers, Buffer Overruns):
821 (Floating Point Portability, Exiting Portably): New sections.
822 (Writing Test Programs): Fix some langauge. Recommend exiting
823 with status 1, not merely nonzero. Clarify exit declaration.
824 (Run Time): Move C exit status stuff to new Exiting Portably section.
825 (Systemology): Mention Posix and levenez. Update v7 reference.
826 (Portable Shell): Mention the Posix shell.
828 2006-04-25 Stepan Kasal <kasal@ucw.cz>
830 * bin/autoconf.as (me): Replace by as_me.
832 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
834 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
835 since as_me isn't set yet.
837 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
839 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
840 a few minor bugs in this area.
842 * doc/autoconf.texi (Programming in M4sh): Comment out the
843 documentation of AS_BASENAME, for now.
844 (Shell Substitutions): Do not use AS_DIRNAME in an example.
845 (Limitations of Builtins) <basename>: Do not refer to
846 AS_BASENAME.
847 * bin/autoconf.as (me): Don't use AS_BASENAME.
848 (dir): Remove the unused variable.
849 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
850 AS_DETECT_REQUIRED. All uses changed.
851 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
852 All uses changed.
853 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
854 (AS_BASENAME): Use "basename --" to protect against leading "-".
855 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
856 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
857 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
858 (_AS_DIRNAME_PREPARE): Likewise.
859 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
860 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
861 (AS_DIRNAME): Use "dirname --".
863 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
865 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
866 of "run time" and "run-time" changed to "runtime", for consistency.
867 * lib/autoconf/fortran.m4: Likewise (in comment).
868 * lib/autoconf/functions.m4: Likewise.
869 * lib/autoconf/general.m4: Likewise.
870 * lib/autoconf/headers.m4: Likewise.
872 * doc/autoconf.texi (Run Time): Document the exit status situation
873 with more accuracy and detail.
875 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
877 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
878 Archive is not officially `GNU' any more. Update URL.
879 (Defining Directories): Likewise
880 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
882 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
884 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
885 newline from the `trap' code to finish `config.log'; the NetBSD
886 /bin/sh resets the exit status after an empty command, as
887 documented in doc/autoconf.texi.
888 Reported by Dalibor Topic <robilad@kaffe.org>.
890 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
892 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
893 Suggested by Bruno Haible.
895 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
897 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
898 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
899 Instead, just list the shells that we know work.
900 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
901 changed. Be more cautious about the _cv_ variable.
902 * tests/tools.at (Syntax of the shell scripts): Check the
903 _cv_ variable once, at first, to avoid an internal autoconf error
904 when sh -n does not work.
906 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
908 * lib/Autom4te/FileUtils.pm: Sync from Automake.
910 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
912 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
913 use ">&-" since we're only 99.999% sure that this is portable,
914 and since the MinGW bug is fixed in a different way.
915 * lib/autotest/general.m4 (AT_INIT): Likewise.
917 2006-04-16 Stepan Kasal <kasal@ucw.cz>
919 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
920 before opening config.log, to avoid hitting a bug on MinGW.
922 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
924 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
925 AS_MESSAGE_LOG_FD before reopening it onto the log file.
926 This works around a MinGW bug reported by Eric Paire.
927 Make sure that all writes to the log file append to it,
928 rather than possibly losing data.
929 * lib/autotest/general.m4 (AT_INIT): Likewise.
931 2006-04-14 Stepan Kasal <kasal@ucw.cz>
933 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
934 description.
936 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
938 * NEWS: Update.
940 * configure.ac (AC_INIT): Bump to 2.59d.
942 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
944 Version 2.59c.
946 * Makefile.maint (news-date-check): Do not require a leading `*'
947 before the release date in NEWS.
949 2006-04-12 Stepan Kasal <kasal@ucw.cz>
950 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
952 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
953 the instantiated file do not contain the string 'datarootdir'
954 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
955 @mandir@, replace the reference '${datarootdir}' by the value.
956 * tests/torture.at (datarootdir workaround): New test.
957 * NEWS: Advertise this temporary fixup.
958 Based on a patch by Bruno Haible, reported and analyzed by
959 Paul Eggert and Noah Misch.
961 2006-04-12 Eric Blake <ebb9@byu.net>
963 * tests/autotest.at (Debugging a failed test): Fix comment.
965 2006-04-12 Stepan Kasal <kasal@ucw.cz>
967 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
968 all the changes since 2006-04-07.
970 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
972 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
973 succeeded, but `ln -s file dir' failed, take care to remove the
974 leftover target before the next test, to prevent its spurious
975 failure; also make sure `ln file dir' works before selecting it.
976 Thanks to Keith Marshall for pointing this out.
977 * THANKS: Update.
979 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
980 assignments in `at_debug_args', so that we put them correctly
981 in the `run' script.
982 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
983 Reported by Eric Blake.
985 2006-04-11 Eric Blake <ebb9@byu.net>
987 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
988 top-level tests after micro-suite has been run. Used in...
989 (Debugging a successful test, Debugging script and environment),
990 (Debugging a failed test): ...these new tests. The first of these
991 is fixed by...
992 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
993 macro, split out from...
994 (AT_INIT): ...here, so that using -d also generates a run script.
995 Document that -d inhibits top-level logging.
996 * doc/autoconf.texi (testsuite Invocation): Document that -d only
997 inhibits top-level logging; debug scripts are created.
999 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1000 check.
1001 * tests/autotest.at (Empty test, Empty check): New test to check it.
1003 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1004 from gcc.
1006 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1008 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1009 the files if a problem appears. Make the empty *.at files
1010 read-only, too. Proposed by Ralf Wildenhues.
1012 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1014 * config/Makefile.am: Add comment to force updated Makefile.in.
1016 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1017 space only patch to this file, this patch causes the Makefile.in
1018 files that include freeze.mk to be updated, and thus have a
1019 newer time stamp again, which in turn makes a pristine CVS
1020 checkout have correct time stamps.
1022 * Makefile.maint (cvs-sv): New macro, to be used..
1023 (config.guess-url_prefix, config.sub-url_prefix)
1024 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1025 point to CVS text checkout of Gnulib files.
1026 (copyright-check): Bump current year.
1027 (announcement): Do not hard-wire `./announce-gen'.
1028 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1029 correctly.
1030 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1031 `chmod +x'.
1032 (wget_files): Update config.guess, config.sub, texinfo.tex by
1033 `wget-update', now that their URLs work again.
1035 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1037 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1038 Problem noted by Paul D. Smith.
1040 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1042 * doc/autoconf.texi: Remove unused words from word list.
1043 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1044 .x-sc_trailing_space: New files.
1046 * doc/standards.texi: Sync from gnulib.
1048 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1049 `LIBOBJDIR' as experimental.
1051 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1052 with a target directory; it's internally implemented as `cp'
1053 anyway, but since Autoconf advertises the possibility to use
1054 a target directory when LN_S is `ln -s', we need to find out.
1055 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1056 analyzed by Keith Marshall <keith.marshall@total.com>.
1058 * THANKS: Update.
1060 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1062 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1063 confdefs.h as-is. In general, if it has backslash-newline or the
1064 like, then it doesn't work either to sort or to remove empty
1065 lines.
1067 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1069 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
1071 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
1073 * lib/autom4te.in (Automake-preselections): Preselect
1074 _AM_SUBST_NOTMAKE.
1076 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1078 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1079 apostrophe within a single-quoted string, as this is the usual
1080 tradition and is easier to read than '"'"'. Don't rely on the
1081 shell treating "$/" like '$/'. Use a more-consistent indenting
1082 style for the trap.
1084 2006-04-09 Eric Blake <ebb9@byu.net>
1086 * tests/autotest.at (Backquote command substitution),
1087 (Multiline backquote command substitution): Remove mistaken
1088 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1089 applied...
1090 (Parenthetical command substitution, Multiline parenthetical
1091 command substitution): here.
1093 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1095 Import macros from gnulib (often changing their name).
1097 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

1109 (Pointers): Add Gnulib URL.
1110 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
1111 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
1112 Gnulib section.
1113 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
1114 suggest a #define rather than a typedef for _Bool, and mention
1115 Gnulib rather than trying to substitute stdbool code.
1116 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
1117 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
1118 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
1119 AC_STRUCT_DIRENT_D_TYPE.
1120 (Particular Types): Mention stdint.h and inttypes.h as standard
1121 headers too.
1122 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
1123 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
1124 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
1125 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
1126 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
1127 (C Compiler): Move AC_C_LONG_DOUBLE to ...
1128 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
1129 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
1130 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
1131 (Coding Style). Don't mention m4_expand_once.
1132 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
1133 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
1134 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
1135 (AC_CHECK_FUNCS): Use it.

1139 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
1140 (AC_HEADER_ASSERT): New macro.
1141 (AC_HEADER_STDBOOL): Don't assume "#error" works.
1142 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
1143 Catch a bug in an HP-UX C compiler.
1144 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
1145 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
1146 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
1147 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):
1148 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
1149 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
1150 New macros.
1152 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
1153 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
1155 2006-04-08 Stepan Kasal <kasal@ucw.cz>
1157 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
1158 of the warning introduced by the 2001-08-28 change.
1160 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
1161 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1163 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
1164 variables shall be overriden by the cache.
1165 * tests/torture.at (AC_ARG_VAR): Test also with a first value
1166 that contains braces.
1168 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1170 Revert the patch from 2006-04-01 and only improve
1171 _AS_DETECT_BETTER_SHELL:
1173 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1174 skip nonexistent directories.
1175 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1176 only shell candidates which exist.
1177 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1178 * lib/autotest/general.m4 (AT_INIT): No need to give three
1179 parameters to _AS_PATH_WALK.
1181 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
1182 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1184 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1185 distinguish m4sugar macros.
1186 * tests/tools.at (autoupdating with aclocal and m4_include):
1187 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1188 test case by Noah Misch <noah@cs.caltech.edu>.
1190 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1192 Revert my change from 2006-03-17, in other words:
1193 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1194 and DUALCASE=1.
1195 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
1196 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
1197 it is set.
1199 2006-04-07 Eric Blake <ebb9@byu.net>
1201 * doc/autoconf.texi (Programming in M4sh): Document that
1202 AS_MKDIR_P exits the script on failure.
1203 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1205 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1207 * config/elisp-comp, config/install-sh, config/mdate-sh,
1208 config/missing, config/mkinstalldirs: Sync from Automake.
1210 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
1211 from Automake.
1213 * doc/make-stds.texi: Sync from gnulib.
1215 2006-04-06 Eric Blake <ebb9@byu.net>
1217 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1218 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1219 2006-04-01.
1221 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
1222 Eric Blake <ebb9@byu.net>,
1223 Paul Eggert <eggert@cs.ucla.edu>,
1224 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1226 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1227 whether `set' quotes correctly: redirect stderr of the tested
1228 `set', and use a subshell, for Ultrix; use `sed' instead of
1229 `grep' for zsh `set' which may write binary output; match only
1230 at the beginning of a line, to avoid false positives.
1231 In order to avoid false positives by unrelated variables with
1232 multiline content, put the dump algorithm in a subshell and
1233 unset all variables containing newlines (except some which are
1234 special to the shell). Warn about cache variables that are
1235 unset.
1237 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1239 * config/config.guess, config/config.sub, config/texinfo.tex:
1240 Sync from upstream.
1242 * tests/mktests.sh: Reword comments.
1244 * tests/mktests.sh: Only skip internal macros starting with
1245 `_AC_' or `__AC_'. Noted by Stepan Kasal.
1246 Update exclusion lists for the test suite to this end:
1247 (AC_ARG_VAR): Do test this now.
1248 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
1249 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
1250 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
1251 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
1253 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
1254 shell issue with double-quoted command substitutions of native
1255 commands.
1256 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
1257 Marshall.
1259 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
1260 no file matches the glob, discard the warning, set `nullglob'.
1261 (syntax-check): Likewise.
1262 (sc_cast_of_x_alloc_return_value): Likewise.
1263 (sc_cast_of_alloca_return_value, sc_error_exit_success)
1264 (sc_prohibit_jm_in_m4, .re-list, sc_unmarked_diagnostics)
1265 (m4-check): Likewise.
1266 (sc_system_h_headers): Do not print rule on execution.
1267 (sc_tight_scope): Do not fail for non-existing `src' directory.
1268 (sc_changelog): Skip the Copyright footer.
1269 * lib/autoconf/lang.m4: Remove trailing space.
1271 * lib/autoconf/status.m4: More replacements to
1272 <tab><space> where this makes sense.
1274 2006-04-06 Stepan Kasal <kasal@ucw.cz>
1276 * tests/Makefile.am (maintainer-check-posix):
1277 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
1279 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
1280 ac_config_<foo>s again, sometimes normalized, sometimes not.
1281 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
1282 (AC_CONFIG_COMMANDS): Do not do so here.
1283 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
1284 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
1285 2005-07-25 rewrite. Noticed by Noah Misch.
1287 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
1288 _AC_PRESERVE_HELP_ORDER, ...
1289 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
1291 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
1292 inside m4_expand_once; it is redundant.
1294 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
1295 for --help from Cygnus `configure.'
1297 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
1299 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
1300 on a patch proposed by Ralf Wildenhues.
1302 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1304 * lib/autoconf/status.m4: Replace <space>''<tab> with
1305 <tab><space> where this makes sense.
1307 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
1308 Noah Misch <noah@cs.caltech.edu>
1310 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
1311 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
1312 * doc/autoconf.texi (Help Formatting): New node.
1313 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
1315 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1317 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
1318 lib/autoconf/specific.m4, lib/autoconf/status.m4,
1319 lib/autoconf/types.m4, lib/autotest/general.m4,
1320 tests/mktests.sh, tests/torture.at: White space cleanup:
1321 remove some SPACE before TAB, or add quoting ('' or @&t@).
1323 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
1325 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
1327 2006-04-05 Eric Blake <ebb9@byu.net>
1329 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
1330 empty test suite works.
1331 * tests/autotest.at (Empty test suite): Remove xfail.
1333 2006-04-05 Noah Misch <noah@cs.caltech.edu>
1335 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
1336 TAGS to ac_config_<foo>s.
1337 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
1338 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
1339 normalizing it, consistent it with previous releases.
1340 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
1342 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1344 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
1345 Use simplified args that Eric Blake originally suggested.
1347 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
1349 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
1350 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
1351 Use 'comm' rather than N instances of grep; this also fixes a bug
1352 whereby substrings were incorrectly matched, causing us to not
1353 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
1354 (exclude_list): Exclude empty macros.
1355 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
1357 Use awk rather than grep -E or egrep, to avoid
1358 portability problems with regular expressions containing newlines.
1359 (exclude_list, ac_exclude_list, au_exclude_list, ac_exclude_script):
1360 Switch from grep to awk syntax.

1441 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1442 initial `rm' of the candidate files...
1443 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1444 the same list in subsequent `rm' calls, and for the temporary

1446 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1447 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1448 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or

1528 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
1529 switch all of them on and of when necessary. Fixes the bug when
1530 m4sugar macros (e.g., m4_define) were expanded after the first
1531 automatic update (e.g., after AC_PREREQ or AC_INIT).
1533 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

1787 _AC_SUBST_FILES fragment. Separate `{' and `r' commands by
1788 newline for portability.
1789 * tests/torture.at (Torturing config.status): Also test 100

2283 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2285 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2286 calls, so that the final expansion of this macro is shorter.
2287 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2288 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2289 the cleanup there. Use AS_VAR_* macros, to be more general.
2290 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2292 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2294 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
2296 2005-09-01 Stepan Kasal <kasal@ucw.cz>
2298 * doc/autoconf.texi (Configuration Headers): Add an index entry
2299 for AH_HEADER.
2301 2005-08-26 Pavel Roskin <proski@gnu.org>
2303 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
2304 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
2305 running xmkmf.
2307 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
2309 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2310 The previous patch didn't work, so try a better one.
2312 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2314 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
2315 in the example. Reported by Bruno Haible.
2316 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2317 "if $undefined_var;" succeeds with my shell.
2319 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2320 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2321 but change the m4_divert_text to m4_divert_once.
2323 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
2325 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2326 Work around bug in Solaris /usr/xpg4/bin/awk.
2327 The bug is present in at least Solaris 8 through 10.
2329 2005-08-24 Stepan Kasal <kasal@ucw.cz>
2331 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2332 some evil values and relying on the fact that $* concatenates the
2333 parameters by the first character from IFS.
2335 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2336 Stepan Kasal <kasal@ucw.cz>
2338 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
2339 first header appears, define AH_HEADER.
2340 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2341 Update limitations about when to call AC_CONFIG_HEADERS.
2342 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2343 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2344 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2345 ``Configuration Actions''; fix their index entries.
2347 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2348 options correctly. Process N-M as M-N if M is smaller than N.
2349 Process ranges correctly so that N-N will run only N.
2350 Sort and uniquify the tests that will be run. If there is more
2351 than one test, reinsert the banners for the tests.
2352 * tests/autotest.at (Keywords): Unmark XFAIL.
2354 2005-08-23 Stepan Kasal <kasal@ucw.cz>
2356 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
2357 before passing the macro name to AH_TEMPLATE.
2359 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2360 now opens log after option processing; in particular, --version
2361 and --help do not touch config.log.
2363 * Makefile.maint: Revert the change from 2005-08-12.
2365 2005-08-22 Stepan Kasal <kasal@ucw.cz>
2367 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
2368 common code to...

2373 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
2374 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
2375 Language cleanup.
2377 * doc/autoconf.texi (Defining Symbols, Changed Results):
2378 Prepend to LIBS, not append, in examples.
2380 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2382 When building in place, set srcdir="."; suggested by Tim Van Holder.
2384 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2385 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2386 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2387 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
2388 does not mean "no --srcdir option".
2390 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2392 * tests/autoscan.at (autoscan): New file.
2393 * tests/suite.at: Use it.
2394 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
2395 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
2397 * tests/autotest.at (Keywords): Test keywords combinations.
2399 2005-08-12 Stepan Kasal <kasal@ucw.cz>
2401 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2402 add "2>&1"; gzip 1.2.4 prints help on stderr.
2404 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2406 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2407 was pushdef'ed twice while popped only once. Push it only once.
2408 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
2410 2005-07-26 Stepan Kasal <kasal@ucw.cz>
2412 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
2413 prefixed by mere "===", not "configure: === ".
2415 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
2417 * Makefile.maint: Update from Bison.
2419 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
2420 "<tab>" in comment, so that the point is understandable.
2422 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2424 Rewrite substantial part of lib/autoconf/status.m4.
2425 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2426 and CONFIG_COMMANDS are not processed in four separate loops.
2427 Instead, there is one main loop. This alows that the common code
2428 is expanded only once, thus config.status (and configure) is smaller.
2430 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2431 the AC_LIST_FILES and cousins macros are no longer used.
2433 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2434 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2435 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2436 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2437 contain the initialization, nor the for loop, nor the associated
2438 commands; all these go to ...
2439 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2440 _AC_OUTPUT_CONFIG_STATUS.
2441 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2442 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2443 (_AC_OUTPUT_FILE): The creation of the sed script ...
2444 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2445 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2446 _AC_OUTPUT_MAIN_LOOP.
2447 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2448 _AC_CONFIG_COMMANDS): Use ...
2449 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2450 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2451 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2452 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2453 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2454 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2455 ... new macros.
2456 (_AC_CONFIG_UNIQUE): Update.
2457 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2458 Replaced by this ...
2459 (_AC_LIST_TAGS): ... new common macro.
2460 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2461 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2462 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2463 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2464 this didn't belong to the `config commands' section.
2465 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2466 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2467 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2468 to the `config commands' section either.
2469 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2470 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2472 ... and many changes to the comments nearby.
2474 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
2475 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
2476 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2477 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
2478 (#define header templates): The comment at the top of the generated
2479 header now includes the name(s) of the source file(s).
2481 Several unrelated small changes:
2483 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2484 parameter to AC_DIAGNOSE.
2485 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2486 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2487 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2488 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2489 with AU::AC_OUTPUT.
2490 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2491 in AC_OUTPUT doesn't double-quote it either.
2492 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
2493 parameters.
2495 2005-07-10 Stepan Kasal <kasal@ucw.cz>
2497 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
2498 versions of Portland Group compiler produce single- and double-quoted
2499 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
2500 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
2502 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2504 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2505 This is a corrected version of yesterday's patch.
2507 2005-07-07 Stepan Kasal <kasal@ucw.cz>
2509 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
2510 path, too; insert a "===" to emphasize the line.
2512 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
2513 ac_cv_build_alias to ac_build_alias.
2514 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
2516 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
2517 change eliminates it. Problem reported by Alexandre Duret-Lutz.
2518 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
2519 (AC_ARG_VAR): ... here.
2520 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
2521 target_alias.
2523 Keep a list of all precious variables and process them with one simple
2524 for loop, instead of expanding all commands, or, OTOH, complicated
2525 processing of output of "set".
2526 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
2527 variable names in new macro...
2528 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
2529 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
2530 a loop to assign all ac_env_* and ac_cv_env_* variables.
2531 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
2532 to INIT_PREPARE.
2533 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
2534 its value to shell variable ac_precious_vars and call
2535 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
2536 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
2537 _AC_ARG_VAR_VALIDATE.
2539 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
2540 and the AC_SUBSTs ...
2541 (AC_INIT): ... here.
2543 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
2544 the ac_subst_files section in config.log.
2546 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
2548 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

2553 * tests/c.at (C keywords): Test AC_C_TYPEOF.
2555 Fix problems reported by Nicolas Joly.
2556 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
2557 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2558 They are generated by the Tru64 v5.1B shell.
2560 2005-07-05 Stepan Kasal <kasal@ucw.cz>
2562 Fix my changes from 2005-07-01; reported by Noah Misch.
2563 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
2564 description, the macro now accepts only a single tag.
2565 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
2567 Fix cases when the varsions of Autoconf and Autotest don't match.
2568 Reported by Noah Misch.
2569 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
2570 at_top_builddir, for compatibility with older autotest.
2571 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
2572 is not set, use at_top_builddir, for compatibility with older
2573 versions of autoconf.
2575 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
2577 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
2578 Problem reported by Patrick Welche.
2580 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
2582 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
2583 sed substitution command, so that we allow | in program prefixes
2584 and program suffixes. (& is a problem anyway; we're not fixing
2585 that here.)
2586 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
2587 configure_input, top_builddir, srcdir, etc.
2588 * lib/autotest/general.m4 (AT_INIT): Likewise, for
2589 PATH_SEPARATOR in AUTOTEST_PATH.
2591 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
2593 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
2594 for loop over config.site files using `set', to allow
2595 directory names containing IFS characters.
2597 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
2599 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
2600 directories with weird names. Apparently some people like living
2601 on the edge. However, improve the test that "pwd" actually does
2602 report a name for the working directory.
2603 * NEWS: Remove the claim that we test for funny chars in dir names.
2605 2005-07-01 Stepan Kasal <kasal@ucw.cz>

2617 about #include <config.h>.
2618 (Generic Functions): Mention the Gnulib project.
2619 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
2621 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
2622 document to output the default config_* lists to config.status.
2623 Don't recognize option --file, if the functionality is not there.
2624 Likewise for --header; moreover, recognize --he and --h as shortcuts
2625 for --help in that case.
2627 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
2628 matches the order of execution. No code changed.
2630 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2632 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for

2649 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
2650 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
2651 (AC_SUBST): Call it.
2652 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
2653 the directory specific variables; but don't call it for configure_input.
2655 2005-06-28 Derek Price <derek@ximbiot.com>
2657 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
2658 addition.
2660 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
2662 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
2663 directory have inherent problems with special characters like spaces,
2664 due to limitations in Make syntax. Problem reported by Alexandre
2665 Duret-Lutz.
2666 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
2667 Also, fix Tru64 porting problem with shell patterns,

2679 from Justace Clutter.
2680 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
2681 variable into diagnostic. Make the diagnostic an error, not a warning,
2682 because we really don't support spaces and suchlike in dir names.
2683 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
2684 Don't worry about backslashes in srcdir; it can't happen now.
2685 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
2686 Simplify ac_optarg handling.
2687 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

2695 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
2697 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
2698 that '\|' is not allowed in BREs; recommend using newline separated
2699 list of patterns instead of multiple -e options.
2701 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
2703 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

2709 2005-06-21 Stepan Kasal <kasal@ucw.cz>
2711 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
2712 b, t, r, w commands require single space, while : cannot have any.
2713 (Special Shell Variables): Fix sed code this in the example.
2714 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
2715 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
2717 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
2718 expand to the empty list. Don't use two pairs of m4_changequote,
2719 it's not necessary.
2721 2005-06-20 Derek Price <derek@ximbiot.com>
2723 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
2725 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
2727 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
2728 * doc/autoconf.texi:
2729 Don't mention Solaris versions so much, if a
2730 problem is common to all extant versions of Solaris. Say "SunOS
2731 4" instead of "SunOS" for SunOS 4.
2732 (awk): Mention more of the limitations of traditional Awk.

2737 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
2738 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
2739 but the implementation is entirely different and is designed
2740 to be compatible with glibc strverscmp.
2741 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
2743 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
2744 on Mac OS X 10.4 reported by Peter O'Gorman in:
2745 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
2746 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):

2758 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
2760 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
2761 (.x.1): Ignore the time stamp in the .TH line when deciding whether
2762 to update the man page. That way, we don't have to check in new
2763 man pages every month.
2765 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
2766 quotes and backslashes. Patch from Derek Price.

2773 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
2775 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
2776 -u, since it outputs chatter if the input files are the same.
2777 Problem reported by Ralf Menzel.
2779 2005-06-08 Derek Price <derek@ximbiot.com>
2781 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
2782 renaming them since they are about to be redefined anyhow.
2784 2005-06-08 Derek Price <derek@ximbiot.com>
2786 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
2787 redefined M4 macros to this node. Document m4_include & m4_sinclude.
2788 Move m4_undefine to alphabetical order.
2790 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
2792 * README: Recommend GNU M4 1.4.3 or later.
2793 * doc/autoconf.texi (Introduction): Likewise.
2794 Reword to avoid some formatting glitches.
2795 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
2796 Clarify explanation of HP compiler bug.
2797 Redo example output tp match current CVS snapshot.
2798 Use @example.org in email addresses when the examples
2799 might get inadvertently cut-and-pasted into user code.
2800 Remove example of autom4te usage that doesn't seem to work now.
2801 Use modern AC_INIT (except when the example is meant to be
2802 shown with Autoconf 2.13).
2803 Update ksh info for Solaris 9 and later.
2804 KB -> kB.
2805 Modernize description of Automake versions a bit.
2806 Don't claim a future version of Autoconf is near.

2812 follows its own advice about quoting better.
2813 Reword to avoid some formatting glitches.
2814 * doc/installt.exi: Reword to avoid some formatting glitches.
2816 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
2817 Tru64 ksh pattern matching bug. Reported against Libtool by
2818 Albert Chin <libtool@mlists.thewrittenword.com> and
2819 Nicolas Joly <njoly@pasteur.fr>.
2821 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2823 m4_cdr of one-member list was [[]] (one-member list containing an
2824 empty string) instead of [] (an empty list. Callers were skewed to
2825 match this misbehaviour. As a consequence of this:
2826 - m4_foreach([x], [], [foo]) expanded to `foo', while
2827 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
2828 This bug has been fixed:
2830 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
2831 expand to an empty string; print error msg if called without
2832 an argument list.
2833 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
2834 misbehaviour; handle [] and [[]] correctly.
2836 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2838 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

2842 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
2844 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
2845 swallow records with more than 99 fields.
2846 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
2847 parse the long line.
2849 2005-06-04 Stepan Kasal <kasal@ucw.cz>
2851 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
2852 swallow literals longer than 399. Reported by Ralf Wildenhues.
2853 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
2854 to workaround this limitation.
2856 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
2858 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
2859 to gfortran, and make these the first two compiler names
2860 checked (following the general autoconf preference for gcc).
2862 2005-06-03 Stepan Kasal <kasal@ucw.cz>
2864 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
2865 (DISTCLEANFILES): Remove $(check_SCRIPTS).
2866 (testsuite): Make sure autotest.m4f is up-to-date before using it.
2868 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
2870 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
2871 expression of unbounded size when processing the --list
2872 option. This runs afoul of a limit of 399 bytes per regular
2873 expression on AIX. Problem reported by Ralf Wildenhues.
2875 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
2877 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
2878 * doc/autoconf.texi (Particular Headers): Reword example
2879 for multiline stdbool replacement.
2880 (Setting Output Variables): Reword text a bit. Don't
2881 give all the details about |#_!!_#|.
2882 Reword description of line replacement.
2884 2005-05-31 Dan Manthey <dan_manthey@partech.com>
2886 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
2887 now contain newlines, and substituted files must be referenced on
2888 a line alone; the sed scripts to substitute them are now very
2889 different.
2890 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
2891 commands can be put in a sed script portably.
2892 * doc/autoconf.texi (Setting Output Variables): Document above
2893 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
2894 use of multiline substitution.

2904 * tests/local.at: Don't attempt to check for negated character
2905 classes in shell scripts. The test was too brittle.
2907 2005-05-25 Stepan Kasal <kasal@ucw.cz>
2909 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
2910 * doc/autoconf.texi (Limitations of Builtins): Document this
2911 limitation.
2913 2005-05-24 Stepan Kasal <kasal@ucw.cz>
2915 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
2916 common code; used in many places in the tree.

2923 messages when ac_unique_file is not found.
2924 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
2925 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
2926 commands, for consistency with AC_MSG_ERROR and such.
2928 * bin/autoconf.as: Make more use of "shift 2" in option processing.
2930 * bin/Makefile.am: Merge the two rules for creating scripts.

2938 2005-05-20 Stepan Kasal <kasal@ucw.cz>
2940 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
2941 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
2942 (ac_top_builddir): ... this ...
2943 (ac_top_build_prefix): ... to this; the old name is also kept, for
2944 backward compatibility.
2945 (ac_top_builddir_sub): New variable, without the trailing slash,
2946 always nonempty.
2947 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
2948 * doc/autoconf.texi (Configuration Actions): Rename
2949 ac_top_builddir to ac_top_build_prefix.
2950 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
2951 at_top_builddir to at_top_build_prefix.

2957 of confdefs.h .
2959 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2961 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
2962 argument to m4_foreach. I guess it was necessary in the past,
2963 but I think it's a no-op now.
2965 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2967 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
2968 ``cat <<_ACEOF'' commands to one.
2969 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
2970 * lib/autoconf/status.m4: On various places, use expr instead of
2971 ``echo|sed.''
2972 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
2973 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
2974 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
2975 a range.
2976 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
2977 the wrong patterns between ``case'' and ``esac.'' The previous
2978 code had false positives.

2982 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
2983 as on 2005-05-02.
2984 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
2985 Mention LIBOBJDIR.

3048 Also, throughout this document, be more careful about white space.
3049 "blank", "white space", and "space" all have different meanings
3050 and we should be careful to say what we mean.

3104 (m4_strip): Update the explanation.
3106 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3108 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):

3111 * lib/autoconf/functions.m4
3112 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):

3114 for you.
3116 2005-04-19 Stepan Kasal <kasal@ucw.cz>

3180 * doc/autoconf.texi (File System Conventions): Warn about
3181 unportable file names.
3182 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3183 (AC_INIT): Use it.
3184 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3185 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3186 ac_pwd, and quote srcdir.
3187 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3189 * doc/autoconf.texi: Fix some systematic formatting problems.
3190 ".)" needs a following @: if not at the end of a sentence, and
3191 similarly for "!)". "etc." should be preceded by a comma.
3192 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3194 2005-03-22 Bruno Haible <bruno@clisp.org>
3196 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3197 argument is often called 'build-aux'.
3199 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3201 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3202 macro AC_TRY_LINK is obsolete.
3203 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3204 `AC_CONFIG_FILES'.
3206 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3208 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3209 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3210 from a Common Lisp's `cl'.
3211 (AC_PROG_CXX): Behave according to the documentation: don't
3212 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3213 make the variable CCC precious; use `cl.exe', not `cl'.
3215 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3216 Alexandre Duret-Lutz <adl@gnu.org>
3218 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3219 /dev/null, as "configure" shouldn't read stdin, and this insulates
3220 us from problems (e.g., when testing for "cl"). Also, do this
3221 redirection before invoking "hostname" or "uname", and keep the
3222 original input stream available via...
3223 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3224 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3225 bother with "</dev/null" since it's now done at the top of
3226 'configure'.
3227 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3228 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

3234 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3236 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3237 newline if neither \c nor -n work, as that would output two
3238 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3240 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3242 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3243 This causes that any required macros inside will get before the if.
3244 * doc/autoconf.texi (autom4te.cache): A typo.
3246 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3248 Undo previous change, except keep the change to
3249 lib/autoconf/programs.m4 that replaced grep with shell
3250 pattern-matching. This is because net-snmp configure reads stdin.
3251 Reported by Noah Misch.
3253 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3255 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3256 from /dev/null, as "configure" shouldn't read stdin, and this
3257 insulates us from problems (e.g., when testing for "cl").
3258 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3259 before invoking "hostname" or "uname".
3260 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3261 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3262 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3263 "</dev/null" since it's now done at the top of 'configure'.
3264 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3265 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3266 Also, replace grep with shell pattern-matching, to save a process.
3268 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3270 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3271 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3272 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3273 compiler.
3275 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3277 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3278 grep -q isn't portable. Improve grep -s explanation.
3279 Problem reported by Dan Manthey.
3281 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
3283 * doc/autoconf.texi (Special Shell Variables): Clarify
3284 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
3286 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
3288 * doc/autoconf.texi: Use @acronym for DJGPP.
3289 Fix some @code's that should have been @env's, and vice versa.
3290 Sort environment variable names.
3291 Mention that shells no longer inherit IFS.
3292 Don't recommend PATH_SEPARATOR=';' so strongly.
3293 Mention that $RANDOM might expand to the empty string.
3294 "symlink" and "soft link" -> "symbolic link".
3295 Improve mktemp description (reported by Bruno Haible).
3297 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
3299 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
3300 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
3301 Likewise.

3307 * NEWS: Mention AT_COPYRIGHT.
3309 * tests/local.at (AT_CMP): Use diff directly on input files rather
3310 than copying them.
3312 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
3313 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
3315 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3316 and Paul Eggert <eggert@cs.ucla.edu>
3318 * tests/autotest.at (Empty test suite): New test.

3325 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
3326 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
3327 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
3328 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
3329 (Standard regular expressions): New test.
3330 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
3331 excess test name quoting.
3332 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
3333 CPPFLAGS to `configure' instead of setting it in `configure'.
3335 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
3336 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
3337 on some platforms.
3339 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
3340 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

3343 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.

3348 * tests/c.at (Extensions): Do not exit early.

3368 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
3370 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
3371 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
3373 Try not to generated lines of unlimited length, as POSIX places a
3374 2047-byte limit on line length of portable text files.
3375 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
3376 Use newline as a separator, not space.
3377 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
3378 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
3379 space.
3381 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3383 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
3384 as_func_*. Add test to check whether positional parameters
3385 are restored after function return.
3387 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
3389 * doc/autoconf.texi (Special Shell Variables): Mention _,
3390 BIN_SH, DUALCASE. Say that variables other than "status" are safe
3391 if they contain a lower-case letter. The DUALCASE problem was
3392 reported by Ralf Wildenhues.
3394 * bin/autoconf.as: Don't exit with status 0 after write failure
3395 with --help or --version.
3396 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

3402 Unicos 9 sed limitations.
3403 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

3405 Fortran 95 (newer Crays).
3407 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
3409 * man/Makefile.am (.x.1): Go back to the simple solution, but take
3410 care to echo the commands, so the user knows what's going on.
3411 Modified from a suggestion by Stepan Kasal.
3413 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

3421 Based on a proposed patch by Ralf Wildenhues.
3423 * man/Makefile.am (.x.1): Make sure the required generated files
3424 are up to date. Problem and original solution proposed by Stepan Kasal.
3425 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
3426 implicit-man-prerequisites): New rules, used by the above.

3432 2005-01-29 Stepan Kasal <kasal@ucw.cz>
3434 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3435 Update the long comment explaining it.
3437 m4_require no longer writes an ``is required by'' line to the
3438 execution stack. It contains only one bit of non-redundant
3439 information: that the macro was required, not called. And even
3440 this bit is useless in most situations: have you ever met a macro
3441 which both calls and requires the same macro?
3443 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3444 (_m4_defun_pro_outer): ... only via this macro, for the outermost
3445 macro.
3446 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
3447 (m4_expansion_stack_pop): Remove the misplaced comment.
3448 (m4_require): Don't put the ``is required by'' line to the
3449 execution stack; slightly improve the out-of-a-defun error message.
3450 (_m4_divert_grow): New macro, counter for the temporary diversions.
3451 (_m4_require_call): Use it.
3452 * tests/m4sugar.at (m4_require): Expect output without the
3453 ``is required by'' messages.
3455 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
3457 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
3458 rather than x for expr.
3460 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
3461 this is safe.
3462 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
3463 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

3473 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
3474 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
3475 from masters, so that FileUtils.pm's update_file provide --force
3476 support.
3477 * bin/autoheader.in: Pass $force to update_file so that
3478 config.h.in is always recreated when --force.
3480 2005-01-24 Stepan Kasal <kasal@ucw.cz>
3482 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
3484 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
3486 * doc/autoconf.texi (Limitations of Builtins): Clarify that
3487 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
3489 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
3491 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3492 Warn about newline stripping in `` and $(). Update Solaris
3493 version to 9.
3494 (Limitations of Builtins): Use expr "X...", not expr "x...", as
3495 X insulates us from future changes to Posix.
3496 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
3497 stripping.
3499 2005-01-19 Stepan Kasal <kasal@ucw.cz>
3501 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

3504 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
3506 * doc/autoconf.texi (Limitations of Usual Tools): Document bug

3517 ulongval to be static, to avoid unwanted GCC warning. Problem
3518 reported by Michael Jennings via Daniel Reed; see
3519 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
3521 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
3523 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

3528 new variables.
3530 2005-01-04 Noah Misch <noah@cs.caltech.edu>
3532 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
3533 not seem to work, assume it does set $(MAKE).
3534 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
3536 2005-01-03 Stepan Kasal <kasal@ucw.cz>
3538 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.

3544 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
3545 (_m4_divert_n_stack): New macro; the expansion is
3546 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
3547 otherwise.
3548 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
3549 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
3550 stored in _m4_divert_diversion or _m4_divert_dump.
3551 (m4_divert_pop): When the parameter is given, compare the symbolic
3552 name with the last diversion pushed on the stack. Previously, the
3553 current diversion was compared with the numeric value of the
3554 diversion given as the parameter.
3555 (m4_require): If the macro hasn't been expanded yet, call ...
3556 (_m4_require_call): this new macro.
3558 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3560 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_ARG_VAR_VALIDATE):

3589 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
3590 signals that the package uses Automake; a `Makefile.am' is typical but
3591 not essential. Reported by Magnus Therning.
3592 * tests/torture.at (autoreconf.): New banner.
3593 (autoreconf and non-AC configure): Rename to `Non-Autoconf
3594 AC_CONFIG_SUBDIRS'.

3611 If the variable to set is already set, set ac_cv_path_$1
3612 to the preset value so caller can assume ac_cv_path_$1
3613 is available. (trivial change)

3863 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use

3983 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns

4083 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
4085 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
4086 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
4087 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
4088 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
4089 * lib/autom4te.in (Automake-preselections): Preselect
4090 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4092 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4094 * lib/autom4te.in (Automake-preselections): Preselect
4095 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4096 trace them.
4098 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4100 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4101 Tru64.
4102 * doc/autoconf.texi (Shellology): Mention BIN_SH.
4103 Document problem with "`""`" in pdksh POSIX mode.
4105 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4107 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4108 with pdksh, too. Problem reported by Patrick Welche via
4109 Gary V. Vaughan.
4110 * doc/autoconf.texi (Shellology): Note that set -o posix is
4111 useful for pkdsh, too.
4113 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4115 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
4116 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
4117 Don't fail if ENV or BASH_ENV is readonly.
4118 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4119 etc. are read only. Problem reported by Ludovic Courtes.
4121 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4123 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
4124 zsh, disable GLOB_SUBST to avoid backslash handling problems.
4125 (trivial change)
4127 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4129 * doc/autoconf.texi (File System Conventions): Warn about
4130 names like "aux". Problem reported by Eric Blake.
4132 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4133 by zero instead of array size, so that we can use any arithmetic
4134 constant expression (instead of requiring an integer constant
4135 expression). This allows us to test expressions like DBL_MAX <
4136 LDBL_MAX, which didn't conform to the C standard using the old
4137 method.
4138 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4139 now that we can do floating-point tests at compile time.
4141 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4143 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4144 and LDBL_EPSILON, as the resulting expression isn't an
4145 integer constant expression and violates the C standard.
4146 Problem reported by Nelson H. F. Beebe. Also, check
4147 for "L" suffix, and check that long double doesn't have
4148 worse range or precision than double, that mixed-mode
4149 arithmetic doesn't generate a diagnostic, that double
4150 constants fit in long double.
4152 2004-06-03 Kevin Ryde <user42@zip.com.au>
4154 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4155 malloc(0) and realloc(NULL,size).
4157 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4158 Bob Proulx.
4160 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4162 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4163 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4164 by Jim Meyering.
4166 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4168 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4169 can be rewritten using if-then-else. Suggested by Bruno Haible.
4171 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4173 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4174 Problem reported by Stepan Kasal.
4176 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4178 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4179 change). Patch reported by Ralf Wildenhues in
4180 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4182 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4183 function F exists if the compiler and linker let you compile an
4184 expression like (F != 0). Recent versions of GCC optimize away
4185 the reference to F in that case, since every function address must
4186 be nonzero, so the link succeeds even if F does not exist.
4187 Problem reported by Manu in
4188 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4190 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4191 "Unix". Many uses changed.
4192 (Limitations of Builtins): Explain better why the ! command isn't
4193 portable.
4195 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4197 * lib/autom4te.in (Automake-preselections): Preselect
4198 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4200 2004-05-19 Kevin Ryde <user42@zip.com.au>
4202 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4203 referencing AC_FUNC_STRERROR_R.
4205 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4206 note pessimistic assumption when cross compiling.
4208 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4210 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4211 (until 2004) invoked subcommands with sh -e, contra POSIX.
4212 Reported by Kevin Ryde.
4214 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4216 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4217 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4218 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4219 `test -f " /usr/bin/grep"', which _always_ failed.
4220 (AC_PROG_SED): Ditto bogus PATH fix.
4221 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4222 requires that grep correctly supports _multiple_ `-e' options, rather
4223 than stating only that grep should accept `-e'.
4225 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4227 Port to C99, which requires that 'exit' be declared.
4229 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4230 to ensure that stdlib.h is included.
4231 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4232 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4233 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4234 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4235 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4236 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4237 when using 'exit' in a test; C99 requires that 'exit' be declared.
4239 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4241 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4242 now prefers 'grep' implementations that accept -e.
4243 (Limitations of Usual Tools): Describe problems of traditional
4244 egrep and fgrep with long input lines, and of traditional grep
4245 with -e.
4246 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4247 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4248 All callers changed. Append /usr/xpg4/bin to the PATH, for
4249 Solaris.
4250 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4251 the user with complaints about multiple -e options.
4252 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4253 Define it with AC_PROG_GREP.
4254 * configure.ac (AC_PROG_GREP): Add.
4255 * lib/freeze.mk (GREP): New macro.
4257 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4259 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4260 a possible candidate only after all others fail, rather than
4261 consulting it first. This improves backward compatibility by
4262 better reflecting the way shell selection occurred in previous
4263 versions of Autoconf, and should help to avoid triggering latent
4264 problems in other packages, such as the one in Automake where zsh
4265 is not handled robustly:
4266 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4267 Although it is not Autoconf's responsibility to work around
4268 problems in Automake, it nevertheless makes sense to avoid
4269 introducing unnecessary incompatibilites.
4271 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4272 Gary V. Vaughan <gary@gnu.org>
4274 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4275 how deeply nested we are when a suitable tool is found, set the
4276 ac_path_TOOL_found flag.
4277 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4278 nested we are in this macro. Break out of all 3 nested loops if
4279 ac_path_TOOL_found is set.
4281 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4283 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4284 of the _AS_PATH_WALK loop too if GNU flavor is found.
4286 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4288 * doc/autoconf.texi (Limitations of Make): Update documentation
4289 for `$<'. New entry `Long lines', based on a report from Simon
4290 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4291 paragraph about DJGPP, based on a mail from Richard Dawe.
4293 2004-04-20 Paul Eggert <eggert@twinsun.com>
4295 * tests/c.at (C keywords): Don't assume that GCC supports
4296 "restrict" and "inline", as sufficiently-old GCC versions do not
4297 (also, GCC configured to be in pedantic C89 mode does not).
4298 Problem reported by Sumit Pandya in:
4299 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4301 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4302 consider -g to work if it generates warnings when plain compiles
4303 don't. Problem reported by Braden McDaniel in:
4304 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4306 * doc/autoconf.texi (Slashes): New section, to document a problem
4307 reported by Jim Meyering in:
4308 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
4310 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
4311 linker output files before linking, to work around IRIX 6 linker bug.
4312 Problem reported by Rainer Orth in:
4313 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
4315 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4317 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4318 best tool so far counter rely on the tool path variable name to
4319 avoid checks for one tool being affected by the results of running
4320 the length check on a previous tool.
4322 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4323 match expression argument, as different greps have different
4324 regular expression flavours.
4325 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4326 literals.
4327 (AC_PROG_EGREP): Pass 'EGREP$'.
4328 (AC_PROG_GREP): Pass 'GREP$'.
4330 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
4332 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
4333 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
4335 2004-03-29 Paul Eggert <eggert@twinsun.com>
4337 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
4338 Types, Specific Compiler Characteristics, System Services,
4339 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4340 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4341 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4342 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
4343 Likewise.
4344 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
4345 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
4346 AC_TYPE_OFF_T): Likewise.
4347 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
4348 Likewise.
4350 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
4351 pacify libtool 1.5.2. Fix quoting problems in sed command.
4353 2004-03-28 Paul Eggert <eggert@twinsun.com>
4355 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
4356 now defines HAVE_DECL_TZNAME if it is declared, when
4357 HAVE_STRUCT_TM_TM_ZONE is not defined.
4358 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
4359 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
4360 for HAVE_TZNAME.
4362 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
4364 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
4365 superfluous backslashing of quotes (") in sed expressions;
4366 thanks to Paul Eggert.
4368 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
4370 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
4371 Fortran compiler is ifort, also added pghpf; thanks to Nelson
4372 H. F. Beebe for the bug report.
4374 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
4376 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
4377 quoted -cmdline argument in Portland Group compiler (bug
4378 reported by Jeffrey J. Barteet).
4380 2004-03-25 Kevin Ryde <user42@zip.com.au>
4382 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
4383 (Run Time): ... here, where it's now mentioned.
4385 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
4387 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
4388 inherits from language Autoconf-without-aclocal-m4.
4389 (Customizing autom4te): Adjust example; the cache must now be
4390 disabled for language Autoconf-without-aclocal-m4.
4392 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
4393 Nathanael Nerode <neroden@twcny.rr.com>
4395 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
4396 AC_CHECK_TOOLS): Warn if a cross-tool is found without
4397 a prefix.
4398 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
4399 AC_CHECK_TARGET_TOOLS): New macros.
4400 * doc/autoconf.texi (Generic Programs): Document
4401 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
4402 AC_CHECK_TARGET_TOOLS, and warn for future changes
4403 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
4404 AC_CHECK_TOOLS.
4405 (Specifying Names): Document the reason for these future
4406 behavioral changes.
4407 * tests/mktests.sh: Do not generate tests for the
4408 new macros.
4409 * NEWS: Document these changes.
4411 * doc/autoconf.texi: Avoid macros with unbraced arguments,
4412 they make TeX hang up.
4414 2004-03-15 Paul Eggert <eggert@bogus.example.com>
4416 * NEWS: New macro AC_CHECK_ALIGNOF.
4417 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
4418 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
4419 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
4420 vowel.
4421 (AC_CHECK_ALIGNOF): New macro.
4422 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
4423 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
4424 those for sizeof.
4426 2004-03-03 Paul Eggert <eggert@twinsun.com>
4428 * bin/Makefile.am (edit): Don't use $< in a context where
4429 POSIX doesn't require support for it. Use $@.in instead.
4430 Problem reported by Anthony N. Frasso in
4431 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
4432 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
4434 2004-02-23 Gary V. Vaughan <gary@gnu.org>
4436 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
4437 from the next generation of Libtool.
4438 * lib/autom4te.in (Autoreconf-preselections): Ditto.
4440 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
4442 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
4443 is not always thread-safe. Report from Nathanael Nerode.
4445 2004-02-18 Paul Eggert <eggert@twinsun.com>
4447 Fix a dependencies problem, stemming from a Autoconf 2.59 build
4448 problem on QNX reported by Stephen Rasku in
4449 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
4451 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
4452 $(m4sh_m4f_dependencies); this removes a FIXME.
4453 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
4454 (MAINTAINERCLEANFILES): Split into pieces,
4455 one per related section. Add $(srcdir)/wrapper.in.
4457 2004-02-09 Paul Eggert <eggert@twinsun.com>
4459 * doc/autoconf.texi (Setting Output Variables): Emphasize that
4460 AC_SUBST provides no portable way to escape literal newlines.
4462 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4463 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4464 Darwin uses -lcrt2.o and there's little point to cataloging all
4465 the system variants. Partial fix reported by Andreas Waechter in:
4466 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
4467 for bug reported by Nelson H. F. Beebe in:

4473 suggested by Paul Eggert.
4474 * lib/autoconf/autoupdate.m4: Correct reference to
4475 acobsolete.m4, suggested by Alexandre Duret-Lutz.
4477 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
4479 * bin/autoupdate.in: Define __file__ so that warnings
4480 refer to the correct file.
4481 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
4482 the behavior of the third argument.
4483 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
4484 correctly the behavior of the third argument. Document
4485 what the three macros that AU_DEFUN defines do. Fix
4486 warning message when the third argument includes $0
4487 (reported by Alexandre Duret-Lutz).
4489 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4490 Eric Sunshine <sunshine@sunshineco.com>
4491 Paul Eggert <eggert@twinsun.com>
4493 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
4494 (AS_INIT): Output shell initialization there. Removed optional
4495 parameter. Expand _AS_SHELL_FN_SPY.
4496 (AS_INIT_WITH_SHELL_FN): Removed.
4497 (_AS_SHELL_FN_SPY): New macro.
4498 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
4499 macros.
4500 (AS_SHELL_SANITIZE): Remove loop to find better shell
4501 and documentation for the parameter.
4502 (_AS_DETECT_BETTER_SHELL): Move it here.
4503 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
4504 (_AS_RUN): Move it here, support testing with eval.
4505 (AS_REQUIRE_SHELL_FN): Require shell functions when
4506 it is used.
4507 (_AS_LINENO_WORKS): Put around braces, we do not
4508 trigger the bash bug anymore.
4509 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
4510 use AS_INIT_WITH_SHELL_FN.
4511 * bin/autoconf.in, tests/wrapper.in: Regenerated.
4513 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4515 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
4516 * doc/autoconf.texi: Don't say that the third parameter
4517 is broken.
4518 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
4519 (AU_DEFUN): Honor the third parameter, create autoupdate
4520 macros with AU_DEFINE.
4521 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
4522 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
4523 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.

4541 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

4543 the 2003-05-22 change, which removed the older years from the list.
4544 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
4546 2004-01-27 Gary V. Vaughan <gary@gnu.org>

4551 possible.
4552 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
4553 AC_PROG_GREP.
4554 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
4555 egrep and fgrep respectively if $GREP -E/-F don't work.
4556 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
4557 _AC_PROG_GREP, and AC_PROG_SED.
4558 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
4559 longest input length accepted by a command.
4560 (AC_PROG_SED): Use it.
4561 * doc/autoconf.texi (Particular Programs): Document the changes.
4562 * NEWS: Updated.
4564 2004-01-27 Paul Eggert <eggert@twinsun.com>
4566 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

4588 2004-01-26 Paul Eggert <eggert@twinsun.com>
4590 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4591 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4592 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4593 not <inttypes.h>. Problem reported by Tim Mooney in
4594 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
4595 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4596 Likewise.
4598 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4599 otherwise "make check" fails because it forbids cmp (I guess
4600 because cmp treats files as binary on DOS-like systems).
4602 * tests/mktests.sh: Update copyright date to 2004, since some tests
4603 have changed in 2004.
4605 2004-01-23 Gary V. Vaughan <gary@gnu.org>

4608 non-truncating sed or gsed program in PATH.
4609 * tests/acprograms.at: Add it.

4611 * NEWS: Updated.
4613 2004-01-15 Paul Eggert <eggert@twinsun.com>
4615 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4616 -std1 disables some useful extensions on Tru64. Problem reported
4617 by N. Lichtmaier in
4618 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
4620 2004-01-14 Paul Eggert <eggert@twinsun.com>
4622 * doc/autoconf.texi (Programming in M4sh): Document that
4623 AS_MKDIR_P succeeds if the destination is a symbolic link
4624 to an existing directory.
4625 (Limitations of Usual Tools): Note that mkdir -p might not
4626 succeed on symlinks to directories.
4628 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
4630 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
4631 * bin/autoheader.in: Grammar fix in message.
4632 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
4633 Test for dir before calling mkdir -p. (trivial changes)
4635 2004-01-13 Eric Blake <ebb9@byu.net>
4637 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
4638 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
4640 2004-01-10 Jim Meyering <jim@meyering.net>
4642 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
4644 2004-01-09 Paul Eggert <eggert@twinsun.com>
4646 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4647 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4648 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4649 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4650 AC_COMPILE_IFELSE, since we now assume our caller invokes
4651 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4652 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4653 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4654 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4656 2004-01-07 Paul Eggert <eggert@twinsun.com>
4658 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4659 `"'...'"`, as it's confusing (and I suspect it may not work on
4660 some platforms). The code was incorrect anyway, as it assumed
4661 that \$ evaluated to itself in that context. Reported by
4662 Alexandre Duret-Lutz.
4664 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
4666 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
4667 and _LT_AC_TAGCONFIG.

4671 * doc/autoconf.texi (One Macro Call): Fix an incorrect
4672 example, and add more examples. Reported by Eric Sunshine.
4674 2004-01-05 Paul Eggert <eggert@twinsun.com>
4676 * doc/autoconf.texi (Limitations of Usual Tools):
4677 Remove warning against "rm -fr" introduced yesterday; it
4678 was a false alarm.
4680 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
4681 autoscan, autoupdate, ifnames): Don't use chmod -w.
4682 * lib/Makefile.am (autom4te.cfg): Likewise.
4683 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
4684 "chmod -w".

4687 Paolo Bonzini <bonzini@gnu.org>
4689 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
4690 by doing lineno substitution only on lines containing "$LINENO".
4692 2004-01-04 Paul Eggert <eggert@twinsun.com>
4694 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
4695 Use "rm -f" to remove conftest.sed, not plain "rm".
4696 Bug reported by David Relson in
4697 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
4699 * Makefile.am (autom4te-update):
4700 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
4701 * Makefile.maint (my-distcheck, do-po-update): Likewise.
4702 * doc/autoconf.texi (Guidelines): Likewise.
4703 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

4708 * tests/Makefile.am (clean-local): Likewise.
4709 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
4710 srcdir): Likewise.
4711 * doc/autoconf.texi (Limitations of Usual Tools):
4712 Warn against "rm -fr".
4714 2004-01-03 Paul Eggert <eggert@twinsun.com>
4716 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
4717 -c -o might not work. From a suggestion by Kevin Ryde.
4718 (C Compiler, Generating Sources, Limitations
4719 of Usual Tools, Limitations of Make, Making testsuite Scripts):
4720 Don't put '-o' after non-options, as POSIX doesn't allow this.
4721 Mention that cc's name might be gcc or c89 or whatever.
4723 2004-01-04 Kevin Ryde <user42@zip.com.au>
4725 * doc/autoconf.texi: Add various further index entries.
4727 2003-12-29 Paul Eggert <eggert@twinsun.com>
4729 * bin/autoreconf.in (autoreconf_current_directory):
4730 Fix typo: mkdir without umask arg.
4732 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
4734 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
4735 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
4736 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
4737 explanation clearer.
4739 2003-12-24 Andreas Schwab <schwab@suse.de>
4741 * doc/autoconf.texi (Default Includes): Fix misspelling of
4742 AC_INCLUDES_DEFAULT.

4746 * configure.ac: Test if sh -n works.
4747 * configure: Regenerate.
4748 * tests/atlocal.in: Store the result here.
4749 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
4750 tools.at, looking in atlocal's ac_cv_sh_n_works instead
4751 of explicitly testing.
4752 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
4753 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
4754 * tests/tools.at (Syntax of the shell scripts): Simplify
4755 using AT_CHECK_SHELL_SYNTAX.

4769 Extracted from AS_SHELL_SANITIZE.
4770 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
4771 macros.
4772 (AS_SHELL_SANITIZE): Move reinvocation code from
4773 _AS_LINENO_WORKS, use it to find out if shell
4774 functions work.
4775 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
4776 does not work.
4777 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
4778 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

4796 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

4824 parameter of AU_DEFUN.

4839 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
4840 than $target since the latter is not usual, add guidelines on when to

4845 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

4924 * Makefile.cfg (local_updates, executable-update): Tweak to be

4986 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug in
4987 pdksh 5.2.14. Bug reported by Ralf Corsepius.
4988 * doc/autoconf.texi (Shellology): Mention the Korn shell and pdksh.
4989 Mention /usr/dt/bin/dtksh on Solaris.
4990 (Shell Substitutions): Warn about $((...)).
4991 (Parentheses): New section.
4993 2003-10-15 Kevin Ryde <user42@zip.com.au>
4995 * doc/autoconf.texi (Function Portability): Add @prindex for exit.
4996 Add putenv and unsetenv. Add sysconf _SC_PAGE_SIZE.
4998 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
5000 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
5001 cross test.
5003 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
5005 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
5006 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
5008 2003-10-10 Andreas Schwab <schwab@suse.de>
5010 * bin/autoheader.in: Avoid empty first line in --version and
5011 --help output.
5012 * bin/ifnames.in: Likewise.
5014 2003-10-09 Paul Eggert <eggert@twinsun.com>
5016 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
5017 Issue a more-informative diagnostic.
5018 Problems reported by Eric Sunshine.
5020 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5022 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
5023 -mGLOB_options_string stuff for Intel ifc, which can cause
5024 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
5025 pattern-matching instead of grep.
5027 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5029 * doc/autoconf.texi: Document new FC Fortran macros.
5031 2003-10-08 Gary V. Vaughan <gary@gnu.org>
5033 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
5034 that future autopoint/aclocal/automake/autoreconf will be able
5035 to trace to find where to install local m4 macros.
5036 * doc/autoconf.texi (Input): Document it.
5037 * NEWS: Updated.
5039 2003-10-06 Gary V. Vaughan <gary@gnu.org>
5041 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
5042 -lcrtbegin.o to list of ignored flags and fix underquoting of
5043 -lcrt[01].o.
5045 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
5047 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
5048 cache variable instead of $G77 to decide whether to include -O2,
5049 since $G77 is specific to Fortran 77.
5051 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5053 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
5054 free" flag. Re-order flags tested into rough order of popularity.
5056 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5058 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
5059 arguments so that it can be used with syntax identical to
5060 AC_PROG_F77, and so that we can more easily decide to
5061 remove/deprecate the DIALECT optional argument in the future if it
5062 proves troublesome.
5063 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
5064 non-freeform-supporting compilers. Document freeform flags.
5066 2003-10-03 Akim Demaille <akim@epita.fr>
5068 * configure.ac: Look for emacs, not macs.
5069 Reported by Eric Sunshine.
5071 2003-10-03 Akim Demaille <akim@epita.fr>
5073 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
5074 * bin/autoreconf.in (autoreconf_current_directory): Create the
5075 AUX_DIR if needed, for sake of automake --add-missing etc.
5076 Suggested by Alexandre Duret-Lutz.
5078 2003-10-03 Akim Demaille <akim@epita.fr>
5080 * configure.ac: Quotation and formatting changes.
5081 (EMACS): Don't set it if it is not recent enough to support
5082 autoconf-mode.el.
5083 From Eric Sunshine.
5085 2003-10-02 Akim Demaille <akim@epita.fr>
5087 * bin/ifnames.in (&scan_file): Skip C++ comments.

5097 Version 2.57f.
5099 2003-09-30 Paul Eggert <eggert@twinsun.com>
5101 * lib/Autom4te/XFile.pm: Use Errno.
5102 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
5103 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
5105 2003-09-30 Akim Demaille <akim@epita.fr>
5107 * config/announce-gen (&print_news_deltas): Extracted from...
5108 (&print_changelog_deltas): here.
5109 (&news_file): Rename as...
5110 (@news_file): this.
5112 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
5114 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
5115 have been created when invoking the compiler.
5116 * tests/fortran.at (GNU Fortran 77): Quote $G77.
5118 2003-09-29 Akim Demaille <akim@epita.fr>
5120 Version 2.57e.
5122 * config/mkinstalldirs: Upgrade.
5124 2003-09-28 Paul Eggert <eggert@twinsun.com>
5126 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
5127 Problem reported by Lars J. Aas in
5128 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
5129 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
5130 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
5131 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
5133 2003-09-26 Akim Demaille <akim@epita.fr>
5135 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5136 directory for AC_CONFIG_COMMANDS' first argument exists.
5137 This makes valid the invocation of _AC_SRCPATH that follows.
5138 Reported by Eric Sunshine.
5139 * doc/autoconf.texi (Configuration Commands): Adjust.
5141 2003-09-26 Akim Demaille <akim@epita.fr>
5143 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
5144 Reported by Ralf Corsepius.
5146 2003-09-26 Akim Demaille <akim@epita.fr>
5148 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
5149 arguments.
5150 Actually, use AU_ALIAS.
5151 From Bruno Haible.
5153 2003-09-26 Paul Eggert <eggert@twinsun.com>
5155 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
5156 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
5157 Problem reported by Eric Sunshine in:
5158 http://mail.gnu.org/archive/html/autoconf-patches/2002-12/msg00014.html
5160 2003-09-26 Akim Demaille <akim@epita.fr>
5162 The test suite are sometimes assigning timings incorrectly.
5163 Reported by Henk Krus.
5164 Diagnosed by Nicolas Joly.
5166 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5167 AT_help_all.
5168 Instead of making AT_help a sequence of assignments to grow
5169 $at_help_all, just make AT_help_all be the growing contents of
5170 $at_help_all, and make a single assignment in...
5171 (AT_INIT): here.
5172 (at_times_skip): Flip the meaning and rename as...
5173 (at_times_p): this.
5174 (AT_INIT): When summarizing the test that ran, remove
5175 $at_times_file after use, and check it is present before trying to
5176 use it.
5178 2003-09-25 Akim Demaille <akim@epita.fr>
5180 Version 2.57d.
5182 * bin/Makefile.am (edit): Handle '@configure_input@'.
5183 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
5184 (ifnames): chmod -w.
5185 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5186 executables, not bin/ executables! Otherwise all the magic needed
5187 to find non installed files is turned off. This caused a failure
5188 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5189 as found in its environment (sent by tests/autoreconf): pointing
5190 to bin/autom4te that could not find its files.
5191 * tests/mktests.sh: Force the replacement of generated files, for
5192 the sake of "mv" program that are interactive when overwriting a
5193 -w file.
5194 * config/install-sh: Upgrade from CVS Automake.
5196 2003-09-23 Paul Eggert <eggert@twinsun.com>
5198 * doc/autoconf.texi (Limitations of Builtins): Document test -h
5199 versus test -L issues.
5201 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
5202 Paul Eggert <eggert@twinsun.com>
5204 Trivial change to support GCC's configuration procedure.
5205 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
5206 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
5207 about inconsistency if the preprocessor is set to give errors for
5208 any warning.
5209 * doc/autoconf.texi (C Compiler Characteristics): Document this.
5211 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
5213 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
5214 and XFile.pm from Automake.

5224 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
5225 from masters.
5227 2003-09-12 Akim Demaille <akim@epita.fr>
5229 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
5230 not asm/types.h.
5232 2003-09-11 Akim Demaille <akim@epita.fr>
5234 * doc/autoconf.texi (Header Portability): linux/random.h.
5235 From Peter Hendrickson.
5237 2003-09-10 Akim Demaille <akim@epita.fr>
5239 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
5240 willing to edit the output files.
5242 2003-09-10 Akim Demaille <akim@epita.fr>
5244 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
5245 and AC_FC_FREEFORM.
5246 * tests/mktests.sh: Skip AC_FC_SRCEXT.
5247 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
5249 2003-09-09 Akim Demaille <akim@epita.fr>
5251 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.

5260 2003-09-07 Paul Eggert <eggert@twinsun.com>
5262 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
5263 Improve the accuracy of the wording about obsolescence.
5264 From a suggestion by Ian Lance Taylor in
5265 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
5267 2003-09-05 Paul Eggert <eggert@twinsun.com>
5269 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
5270 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
5272 2003-09-04 Akim Demaille <akim@epita.fr>
5274 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
5275 AC_FUNC_WAIT3.
5277 2003-09-04 Akim Demaille <akim@epita.fr>
5279 * bin/autom4te.in: Use &fatal where more appropriate than &error.
5280 (freeze): When exiting, use $exit_code.
5281 * lib/autoconf/fortran.m4: Comment changes.
5283 2003-09-04 Akim Demaille <akim@epita.fr>
5285 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
5287 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
5289 Add support for newer Fortran dialects. The F77 interface is
5290 unchanged, and continues to support Fortran 77. New FC macros
5291 correspond to all the old F77 macros, with output variables FC,
5292 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5293 available dialect, but older dialects can be specified. There are
5294 new macros AC_FC_SRCEXT to set the source extension, and
5295 AC_FC_FREEFORM to accept free-form source files.
5297 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
5298 New macros.
5299 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
5300 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
5301 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
5302 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

5310 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
5311 AC_FC_SRCEXT, AC_FC_FREEFORM):
5312 New macros.
5313 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
5314 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
5315 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
5316 Rewrite in terms of the above.
5317 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
5318 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
5319 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
5320 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
5322 2003-09-02 Paul Eggert <eggert@twinsun.com>
5324 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
5325 Document problems with timestamp resolution that 'make', 'cp -p', and
5326 'touch -r' have.
5328 2003-08-27 Akim Demaille <akim@epita.fr>
5330 * tests/m4sugar.at (cross_warning): Make sure to enable the
5331 output, so that we can track spurious m4sugar output.
5332 * tests/local.at: Require 2.57.
5333 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5334 are defaulted by AT_CHECK anyway.
5335 Use AT_CHECK_AUTOM4TE.
5336 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
5337 missing dnl.
5339 2003-08-27 Akim Demaille <akim@epita.fr>
5341 * bin/autoheader.in: Issue the "Using auxiliary..." message only
5342 when -Wobsolete is set.
5343 Set it on by default.
5344 Suggested by Klee Dienes.
5346 2003-08-27 Akim Demaille <akim@epita.fr>
5348 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More

5355 after AC_OUTPUT.
5357 2003-08-25 Akim Demaille <akim@epita.fr>
5359 * config/announce-gen, GNUmakefile, Makefile.maint: Update from

5388 2003-08-22 Akim Demaille <akim@epita.fr>
5390 Output stack traces in warnings.
5392 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
5393 Replace the former...
5394 (m4_warn): Pass the call stack to _m4_warn.
5395 * bin/autom4te.in: Adjust to output the call stack.
5396 * tests/m4sugar.at (m4@&t@_warn): Adjust.
5398 2003-08-22 Akim Demaille <akim@epita.fr>
5400 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
5401 * bin/autom4te.in: Adjust.
5403 2003-08-21 Akim Demaille <akim@epita.fr>
5405 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
5406 (&verbose): Remove.
5407 (&getopt): Adjust the note and verb channels, depending upon
5408 --verbose.
5409 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
5410 * bin/autoupdate.in: Adjust.
5411 Use &verb, not &verbose.
5413 2003-08-21 Akim Demaille <akim@epita.fr>
5415 * bin/autoheader.in (&parse_args): Use &parse_warnings and
5416 &parse_WARNINGS.
5417 ($help): Use Autom4te::ChannelDefs::usage.
5418 * bin/autoscan.in: Use Autom4te::ChannelDefs.
5419 * lib/Autom4te/General.pm: Don't export error: you don't own it.
5421 2003-08-21 Akim Demaille <akim@epita.fr>
5423 First stab at preserving warnings between calls to autom4te,
5424 including when the cache is used.
5426 There are still several issues: (i) there are too many runs of m4
5427 (one for include, one for warnings, and some more), (ii) warnings
5428 spreading on several lines are not handled gracefully, (iii) the
5429 code meant to have the call stack display for errors does not work
5430 (its handling should move from m4 to autom4te).
5432 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5433 Use them.
5434 (@preselect): Add m4_warn.
5435 ($exit_status): Remove, use $exit_code.
5436 ($help): Use Autom4te::ChannelDefs::usage.
5437 (&handle_m4): No longer define the m4_warnings.
5438 At each run, extract and report the warnings.
5439 Always cache the result, including if the exit status is on
5440 failure, since if nothing changes, we should result in the same
5441 failure, hence we can use the cache.
5442 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5443 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5444 Remove.
5445 (m4_warn): Redefine as a do-nothing: it is its invocation that
5446 matters, as warnings are now reported via traces.
5447 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5448 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5449 the latter reveals calls to the former.
5451 Adjust the tests.
5453 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
5455 2003-08-21 Akim Demaille <akim@epita.fr>
5457 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
5458 Use them.
5460 2003-08-21 Akim Demaille <akim@epita.fr>

5490 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5491 (&xsystem, &contents): Remove, since they are exported by...
5492 * lib/Autom4te/FileUtils.pm: this.
5493 More perldoc.
5494 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
5495 * lib/Autom4te/FileUtils.pm: here.
5497 2003-08-20 Akim Demaille <akim@epita.fr>

5556 2003-08-13 Derek Price <derek@ximbiot.com>
5558 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
5559 output.
5561 2003-08-12 Derek Price <derek@ximbiot.com>
5563 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
5564 (AT_CHECK_NOESCAPE): Move core functionality to...
5565 (_AT_CHECK): ...this new macro.
5567 2003-08-07 Derek Price <derek@ximbiot.com>
5569 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
5570 (AT_CHECK_NOESCAPE): ...to this new macro.
5572 2003-07-31 Paul Eggert <eggert@twinsun.com>
5574 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
5575 in Bash 2.01. Problem reported by Brian Gough in
5576 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
5578 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
5580 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
5581 -lcrt1.o, for OS X. (trivial change)
5583 2003-07-07 Paul Eggert <eggert@twinsun.com>
5585 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
5586 inside '#ifndef __cplusplus'. Problem reported by
5587 Bob Friesenhahn.
5589 2003-07-06 Bill Clarke <llib@computer.org>
5591 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
5592 'long', not 'int', for benefit of Sun's recent C++ compilers
5593 (trivial change). See:
5594 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
5595 (This really should be 'intptr_t', not 'long', but that would
5596 take more work.)
5598 2003-06-25 Akim Demaille <akim@epita.fr>
5600 * lib/Makefile.am (autom4te.cfg): Make it read only.
5601 Depend on Makefile since it contains substitutions.
5602 From Paolo Bonzini.

5604 This change was made on autom4te.cfg which is generated.
5605 Reported by Raja R. Harinath.
5607 2003-06-25 Akim Demaille <akim@epita.fr>
5609 * doc/autoconf.texi (Header Portability): sys/mount.h.
5610 From Gareth McCaughan.
5612 2003-06-23 Akim Demaille <akim@epita.fr>
5614 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5615 not all of them. This fixes 1. the fact that when testing
5616 Autoconf there are many many config.log, 2. the incorrect use of
5617 top_srcdir to find config.log.
5618 Don't mix the detailed output of failed test with the summary of
5619 failures. Rather, append detailed log afterwards.
5621 2003-06-23 Akim Demaille <akim@epita.fr>
5623 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
5624 always run: output config.log on $at_group_log.
5626 2003-06-23 Akim Demaille <akim@epita.fr>
5628 * tests/torture.at (#define header templates): Don't use quotes in

5631 2003-06-23 Akim Demaille <akim@epita.fr>
5633 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
5634 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
5635 * tests/atspecific.m4: Rename as...

5638 * tests/local.at: here.
5639 * tests/Makefile.am: Adjust.
5640 * doc/autoconf.texi (testsuite Scripts): Adjust.
5642 2003-06-21 Kevin Ryde <user42@zip.com.au>
5644 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
5645 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
5646 ensuring we add -std1 for full-ANSI.
5648 * doc/autoconf.texi (hdrindex): New macro.

5651 2003-06-20 Akim Demaille <akim@epita.fr>

5655 2003-06-20 Akim Demaille <akim@epita.fr>
5657 Version 2.57a.
5659 2003-06-20 Akim Demaille <akim@epita.fr>
5661 * bin/autom4te.in: Don't rely on $HOME being defined.
5662 Reported by Marc Espie as PR/233.
5664 2003-06-20 Akim Demaille <akim@epita.fr>
5666 * lib/autotest/general.m4: Use at_times_file only if used.
5667 From Nicolas Joly.
5669 2003-06-20 Akim Demaille <akim@epita.fr>
5671 * config/config.guess, config/config.sub, config/elisp-comp,
5672 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
5673 Update from masters.
5675 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
5677 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
5678 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
5679 (TEST_SCRIPT): New diversion.
5680 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
5681 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
5682 (AT_INIT): Support for expected failures.
5684 2003-06-02 Akim Demaille <akim@epita.fr>
5686 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
5687 changes.
5688 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
5689 Autoconf nor Automake.
5690 (&contents): New, from Automake.
5691 PODify.
5693 2003-05-28 Paul Eggert <eggert@twinsun.com>
5695 * NEWS, doc/autoconf.texi (Particular Functions),
5696 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
5697 is the inverse of localtime.
5699 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
5701 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
5702 (handle_exec_errors): New function. Work around $! being
5703 altered by WEXITSTATUS.
5704 (xqx, xsystem): Use handle_exec_errors.
5706 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
5708 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
5709 Do not call `_exit()', simply modify `$?'.
5710 (xsystem): Reset $! before running system, and check it afterward.
5711 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
5712 63 for version mismatches.
5714 2003-05-23 Akim Demaille <akim@epita.fr>
5716 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
5717 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
5718 the middle of a line).
5719 * lib/m4sugar/m4sugar.m4: Likewise.
5720 Remove useless spaces in comments.
5722 2003-05-23 Akim Demaille <akim@epita.fr>
5724 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
5725 exit 63, so that we (or Automake's "missing") can tell the
5726 difference with a plain failure.
5727 * doc/autoconf.texi (Notices): Adjust.
5729 2003-05-23 Akim Demaille <akim@epita.fr>
5731 * Makefile.am, bin/Makefile.am, config/Makefile.am,
5732 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
5733 White spaces cleanup.
5735 2003-05-22 Jim Meyering <jim@meyering.net>
5736 Paul Eggert <eggert@twinsun.com>
5738 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
5739 Remove `#include <stdlib.h>' from the list; we should never
5740 make confdefs.h include <stdlib.h> or <cstdlib>, because the
5741 resulting namespace pollution would cause other tests to fail.
5742 Configure scripts run with some older versions of g++ and HP's
5743 aCC would fail due to such an #include. Problems reported by
5744 Matthew Mueller in <http://bugs.debian.org/120704> and by
5745 Keith Bostic in
5746 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
5747 In the test, use the test declaration before including <stdlib.h>,
5748 as that's closer to how it'll be used.
5750 2003-05-23 Akim Demaille <akim@epita.fr>
5752 * doc/autoconf.texi (Header Portability): ucred.h.
5753 From Ian Redfern.
5755 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5757 Overhaul Autotest's logging: generate separate log files
5758 in testsuite.dir/NNN/testsuite.log, and append them to
5759 testsuite.log instead of re-running the test verbosely.
5761 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
5762 file descriptor, write 0 to at_status_file instead of setting
5763 at_status=0, initialize some new variables (at_status_file,
5764 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
5765 to rerun the tests, instead append the at_group_log to the
5766 at_suite_log when a test fails.
5767 (AT_SETUP): pipe the test case's output into at_tee_pipe,
5768 with the AS_MESSAGE_LOG_FD redirected to stdout.
5769 (AT_CLEANUP): save the output status in $at_status_file
5770 and restore it, redirect the AS_MESSAGE_LOG_FD back to
5771 its original place.
5772 (AT_CHECK): since tests are run with a redirected stdout,
5773 and used to be re-run in verbose mode, turn some $at_verbose
5774 into echo, and don't redirect the output of testing stdout
5775 and stderr.
5777 * lib/autotest/autoconf.texi (testsuite Scripts): Update
5778 the name of the debugging directory and information about
5779 its contents.
5781 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5783 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
5784 parameter.
5786 2003-05-22 Akim Demaille <akim@epita.fr>
5788 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4
5789 * lib/autoconf/fortran.m4 lib/autoconf/general.m4
5790 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4

5807 Suggested by Jim Meyering.
5809 2003-05-22 Akim Demaille <akim@epita.fr>
5811 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
5812 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
5813 Reported by Jim Meyering.
5815 2003-05-22 Akim Demaille <akim@epita.fr>
5817 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

5836 * bin/autoupdate.in ($m4): Fix quotation.

5848 AC_CHECK_HEADERS_NEW): New tests.
5850 2003-05-17 Akim Demaille <akim@epita.fr>
5852 * lib/autoconf/functions.m4: Use the default includes so that
5853 memcmp be declared before being tested.
5854 Reported by Sander Niemeijer.
5855 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.

5857 AC_INCLUDES_DEFAULT.
5859 2003-05-17 Akim Demaille <akim@epita.fr>
5861 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
5862 * doc/autoconf.texi (Obsolete Macros): Adjust.
5863 Reported by Werner LEMBERG and Debian Bug 190886.
5865 2003-05-16 Akim Demaille <akim@epita.fr>
5867 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
5868 user name space clashes.
5869 Reported by Bruno Haible.
5871 2003-05-16 Akim Demaille <akim@epita.fr>
5873 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
5874 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
5875 them uniform, and more robust to Perl special characters.
5876 Reported by Martin Mokrejs.
5878 2003-05-14 Akim Demaille <akim@epita.fr>
5880 * tests/foreign.at (Libtool): Skip all Libtools pre 1.4.
5882 2003-05-14 Akim Demaille <akim@epita.fr>
5884 * doc/autoconf.texi (Header Portability): X11/extensions/scrnsaver.h,

5889 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Improve the
5890 message.
5891 From Matthias Andree.
5893 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
5895 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
5896 and truncate.
5898 2003-05-06 Akim Demaille <akim@epita.fr>
5900 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
5901 longer updates aclocal.m4 if useless, (ii) if a file m4_included
5902 by aclocal.m4 is changed it might require the importing of another
5903 m4 extension file, i.e., aclocal must be run.
5905 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
5906 (&parse_args): Use --force with aclocal if required and supported.
5907 (&autoreconf_current_directory): Use &run_aclocal.
5909 2003-05-06 Akim Demaille <akim@epita.fr>
5911 Lock autom4te's cache.
5913 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
5914 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
5915 argument instead of a file name, so that the request file remains
5916 open during the whole autom4te run.
5917 ($icache_file): New.
5918 (&freeze): Lock the $icache_file.
5920 2003-04-29 Derek Price <derek@ximbiot.com>
5922 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
5923 seperator with m4_append_uniq(). It doesn't work.
5924 (AT_CLEANUP): Add `;' to end of at_help_all.
5925 (AT_INIT): Allow --keywords to be specified more than once. When
5926 grepping $at_help_all for keywords, use the field and keyword
5927 seperators to ensure a complete keyword match. Alter at_prev handling
5928 to support the new --keywords behavior.
5930 2003-04-27 Karl Berry <karl@freefriends.org>
5932 * doc/autoconf.texi: Make the dir entries in the autoconf manual
5933 align better with others. I also made some of the individual
5934 entries on one line, for brevity and to make it easier for me to
5935 sort my dir-example file in the Texinfo distribution :).
5937 2003-04-12 Jim Meyering <jim@meyering.net>
5939 * NEWS: Mention the new macro.
5940 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.

6002 header causes problems.
6004 2003-03-28 Akim Demaille <akim@epita.fr>
6006 * tests/torture.at (Configuring subdirectories): Require aclocal
6007 1.4, otherwise the test fails, as it does support configure.ac.

6030 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
6031 obsolete AC_HELP_STRING.
6032 (AC_HELP_STRING): AU_DEFUN to...
6033 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
6034 * tests/m4sh.at (AS_HELP_STRING): New test.
6036 * tests/acgeneral.at: Regenerated.
6038 2003-03-26 Derek Price <derek@ximbiot.com>
6040 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
6041 sense. Verbosify the diversion definitions comment.

6081 (Automake): Automake 1.5+ no longer requires special tools to be
6082 present on the developer's host.
6084 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
6086 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set

6091 * bin/autoreconf.in (BEGIN): Likewise.
6092 * bin/autoscan.in (BEGIN): Likewise.
6093 * bin/autoupdate.in (BEGIN): Likewise.

6098 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
6099 to cope with DOS-style absolute paths, when constructing
6100 ${ac_make}.
6102 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
6103 When constructing paths with IFS=:, quote the path. If we're
6104 constructing a DOS-style absolute path, we don't want to split it
6105 on the colon.
6107 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
6108 in description.
6110 2003-02-25 Pavel Roskin <proski@gnu.org>

6122 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
6123 to fix a mismatch between example and discussion.
6125 2003-02-24 Kevin Ryde <user42@zip.com.au>
6127 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
6128 format starting with "-".
6130 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6132 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
6133 is not portable inside Makefile.
6135 2003-02-20 Akim Demaille <akim@epita.fr>
6137 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
6138 compiler says yeah, but preproc says nope, compiler is right.
6139 Conversely, prompt the reader to send a bug report to the
6140 maintainers of the package, not of Autoconf.
6142 2003-02-20 Klee Dienes <kdienes@apple.com>
6144 * bin/autoreconf.in (autoreconf_current_directory): Properly
6145 handle an empty aclocal.m4.

6150 $ac_prefix_program.
6151 From Larry Jones.
6153 2002-12-23 Paul Eggert <eggert@twinsun.com>
6155 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
6156 innocuous variant befor including <limits.h> or <assert.h>. This
6157 works around a bug reported by Albert Chin: HP-UX 11i
6158 (and earlier versions) have a <limits.h> that declares
6159 gettimeofday and many other functions.
6161 2002-12-03 Paul Eggert <eggert@twinsun.com>
6163 Version 2.57.
6165 * NEWS, configure.ac: Update version.
6167 * doc/fdl.texi: Upgrade to FDL version 1.2.
6169 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6170 nontrivially in main's body, so that f's external declaration is
6171 not optimized away in AIX. This should fix the bug reported by
6172 Martin Frydl in
6173 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
6175 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
6176 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6177 defined, to support freestanding compilers. This should fix the
6178 bug reported by Momchil Velkov in
6179 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6181 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
6182 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

6187 * Makefile.maint (www-gnu): New macro.
6188 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
6189 the location has moved.
6191 2002-12-02 Martin Frydl <martin@systinet.com>
6193 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
6194 \(.*\) match is too long and there is something more to be checked.
6195 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
6197 2002-11-15 Akim Demaille <akim@epita.fr>

6203 * config/move-if-change: Indenting changes.
6204 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
6205 * configure.ac (AM_INIT_AUTOMAKE): here.
6206 Require 1.7.1.
6208 2002-11-14 Akim Demaille <akim@epita.fr>
6210 Version 2.55.
6212 * config/config.guess, config/config.sub, config/install-sh:
6213 Update from masters.
6215 2002-11-14 Akim Demaille <akim@epita.fr>
6217 * Makefile.maint: Sync with Bison, i.e.:
6218 (po-check): Scan .l and .y files instead of the
6219 .c and the .h files that they generate. This fixes the bug
6220 reported by Tim Van Holder in:
6221 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6222 Look for N_ as well as for _. Try to avoid matching #define for
6223 N_ and _.
6224 From Paul Eggert.
6226 2002-11-14 Akim Demaille <akim@epita.fr>
6228 * doc/autoconf.texi (C Compiler): Compiling several files at once.
6229 From Paul Eggert and Albert Chin-A-Young.
6231 2002-11-14 Akim Demaille <akim@epita.fr>
6233 * doc/autoconf.texi (C Compiler): Solitary backslashes.
6234 From Paul Eggert and Albert Chin-A-Young.
6236 2002-11-14 Kevin Ryde <user42@zip.com.au>
6238 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
6239 than assigning in main, to avoid HP cc +O3 optimizing it away.
6241 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
6243 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
6244 option. Process --recheck after parsing all options. Pass -q
6245 option to configure on --recheck.
6246 (AC_OUTPUT): Pass -q from configure to config.status.
6247 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
6248 arguments to record.
6249 * doc/autoconf.texi (config.status Invocation): Document
6250 config.status -q option.
6252 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
6254 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
6255 Makefile.in if Makefile.am exists.
6256 (output): Strip `.am' from Makefiles. Don't
6257 output AC_CONFIG_FILES if no Makefiles were found.
6259 2002-11-07 Akim Demaille <akim@epita.fr>
6261 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.

6266 2002-11-06 Akim Demaille <akim@epita.fr>
6268 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
6269 declaration in extern "C" too.

6272 2002-11-06 Akim Demaille <akim@epita.fr>
6274 * tests/torture.at (Configuring subdirectories): Don't use grep
6275 -w.
6276 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
6277 Reported by Ezra Peisach.
6279 2002-11-05 Akim Demaille <akim@epita.fr>
6281 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6282 Remove.
6283 We _have_ to stop using the old compatibility scheme that tried to
6284 avoid useless backslashes because Libtool 1.4.3 contains a
6285 AC_DEFINE([error_t], [int],
6286 [Define to a type to use for \`error_t' if it is not
6287 otherwise available.])
6288 We _have_ to quote the single quote and backslashes with \. The
6289 old compatibility scheme saw that ` was backslashed, and therefore
6290 did not quote the single quote. Hence before this patch, Autoconf
6291 was not compatible with Libtool.
6293 2002-11-04 Paul Eggert <eggert@twinsun.com>
6295 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

6300 2002-11-04 Akim Demaille <akim@epita.fr>
6302 Version 2.54c.
6304 * Makefile.maint (update, cvs-update, po-update, do-po-update):
6305 New.
6306 * config/texinfo.tex: Update.
6308 2002-11-03 Akim Demaille <akim@epita.fr>
6310 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
6311 from...
6312 (&autoreconf): here.
6313 ($help, $make, &parse_args, &autoreconf_current_directory):
6314 Support -m/--make.
6315 * doc/autoconf.texi (autoreconf Invocation): Adjust.
6317 2002-10-31 Bruno Haible <bruno@clisp.org>
6319 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.

6326 2002-10-31 Akim Demaille <akim@epita.fr>
6328 The test suite was no longer checking for trailing envvars and files.
6330 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
6331 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
6333 2002-10-31 Akim Demaille <akim@epita.fr>
6335 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
6336 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
6337 Make variable, not a shell variable.
6338 Suggested by Bruno Haible.
6340 2002-10-31 Akim Demaille <akim@epita.fr>
6342 * bin/autom4te.in (load_configuration): Reject #args out of any
6343 language.
6345 2002-10-31 Akim Demaille <akim@epita.fr>
6347 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
6348 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
6349 (_AC_RUN_IFELSE): Use it.
6350 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
6351 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
6352 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
6353 inline it.

6359 Suggested by Tim van Holder.
6361 2002-10-29 Paul Eggert <eggert@twinsun.com>
6363 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
6364 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
6365 Problem reported by Bruno Haible.
6367 2002-10-29 Akim Demaille <akim@epita.fr>
6369 * doc/autoconf.texi (Header Templates): Put also in words what the
6370 pictures says to assist free style readers.
6371 (Customizing autom4te): s/--cache=/--cache /.
6373 2002-10-29 Akim Demaille <akim@epita.fr>
6375 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
6376 sys/wait.h.
6377 sparc_address_test returns void.
6378 Use it with an argument, as prototyped.
6379 From Bruno Haible.
6381 2002-10-29 Akim Demaille <akim@epita.fr>
6383 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

6389 * tests/torture.at (Deep Package): New test.

6395 * bin/autoreconf.in (&parse_args, $help): Support --warnings.
6396 * doc/autoconf.texi (Invoking autom4te): Rename as...
6397 (autom4te Invocation): this, for consistency with the other nodes.
6399 2002-10-29 Akim Demaille <akim@epita.fr>
6401 * lib/autom4te.in (Autoconf): s/automate/autom4te/.
6402 Reported by Ralf Corsepius.
6404 2002-10-29 Akim Demaille <akim@epita.fr>
6406 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

6408 Reported by Ralf Corsepius.
6410 2002-10-28 Akim Demaille <akim@epita.fr>
6412 * configure.ac: Bump to 2.54c.

6623 2002-10-22 Akim Demaille <akim@epita.fr>
6625 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

6629 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""

6632 2002-10-22 Akim Demaille <akim@epita.fr>

6681 longer required can still cause errors.
6682 Reported by Alexandre Duret-Lutz.
6684 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
6685 to frozen files in @ARGV, as @ARGV must remain being a list of

6687 (&files_to_options): New function.
6688 (&freeze): Use &error.
6689 (&up_to_date): If a file that was included according to the cache
6690 is no longer there, then the output is out dated.
6691 (&main): Don't even check whether a file is up to date is anyway
6692 --force is given.
6693 * tests/tools.at (autom4te cache): New.

6700 Factor some code.
6701 (&autoreconf): Report the directories we enter *and leave*, so
6702 that error messages can be easily located, and use GNU Make
6703 format, so that Emacs' compile mode understands us.
6704 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
6705 if some file was changed instead of `print'.
6706 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

6740 file name to enable parallel executions.
6741 From Sam Varshavchik.
6743 2002-10-08 Akim Demaille <akim@epita.fr>
6745 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
6746 aclocal invocation, as Gettext macros might not be visible to
6747 aclocal.
6748 Instead of blindly running autopoint, scan configure.ac (not the
6749 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
6750 Reported by Paul D. Smith.
6752 2002-10-08 Paul Eggert <eggert@twinsun.com>
6754 Work around problems found when POSIXLY_CORRECT=1 is set.
6755 None of this seems to have anything to do with POSIX, really,
6756 but it's how Perl getopt works.
6757 * bin/autom4te.in (parse_args): Configure GetOpt with
6758 "permute", too.
6759 * doc/autoconf.texi (Invoking autom4te):

6782 * tests/torture.at (Configuring subdirectories): Be robust to
6783 users who use config.site to require for a cache: in this case,
6784 the two last configure runs, using two different sets of
6785 arguments, trigger a legitimate error.
6787 2002-09-28 Akim Demaille <akim@epita.fr>

6806 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
6807 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

6822 tests/autom4te itself.
6823 * lib/autoscan/Makefile.am: Include freeze.mk.
6824 (autoscan.list): New target --this file is no longer a source.
6825 (autoscan.pre): New file.

6832 tracking changes in autoscan.list.
6833 * lib/autoscan/autoscan.list (function): Strip comments, sort.
6835 2002-09-28 Akim Demaille <akim@epita.fr>

6848 `functions' line is now prefixed with `function:'.
6849 * bin/autoscan.in (&init_tables): Adjust.
6851 2002-09-28 Akim Demaille <akim@epita.fr>
6853 From now on, autoscan files must always map a macro name to a
6854 word: there is no `default' macro for autoscan.
6856 * bin/autoscan.in (&init_tables): Reject entries with no macro at
6857 all.
6858 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
6859 explicit.
6861 2002-09-28 Akim Demaille <akim@epita.fr>
6863 * bin/autoscan.in (%c_keywords): Remove.

6937 2002-09-13 Akim Demaille <akim@epita.fr>
6939 Version 2.54.
6941 * config/config.sub, config/config.guess: Update.
6942 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
6943 * Makefile.am: Adjust.
6945 2002-09-13 Akim Demaille <akim@epita.fr>
6947 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
6948 reading config.log when the compiler is rejected.
6949 Suggested by Guido Draheim.
6951 2002-09-13 Akim Demaille <akim@epita.fr>
6953 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
6954 (chdir_init) might hang when stat'ing mounted directories.
6955 Reported by Vance Shipley.
6957 2002-09-12 Akim Demaille <akim@epita.fr>
6959 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
6960 the lists.
6962 2002-09-12 Akim Demaille <akim@epita.fr>
6964 * doc/autoconf.texi (Defining Symbols): Present two different
6965 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
6966 difference between 1 argument calls, and 2-3 argument calls.
6968 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
6970 * doc/autoconf.texi: Review grammar and punctuation.
6972 2002-09-11 Paul Eggert <eggert@twinsun.com>
6974 * doc/autoconf.texi: Fix minor formatting, spelling, and
6975 grammatical typos.
6976 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
6977 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
6978 is obsolescent.
6980 2002-09-11 Akim Demaille <akim@epita.fr>
6982 * doc/autoconf.texi (Questions): Rename as...
6983 (FAQ): this.
6984 (Defining Directories): New.
6986 2002-09-09 Akim Demaille <akim@epita.fr>
6988 * doc/autoconf.texi (Making testsuite Scripts): Update.
6989 Suggested by Nishio Futoshi.
6991 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
6993 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
6994 plain `@' is wanted.
6996 2002-09-09 Akim Demaille <akim@epita.fr>
6998 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
6999 `duplicates', since the algorithm was too naive and could keep
7000 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7001 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7002 Reported by Ralf Corsepius.
7003 * tests/torture.at (Configuring subdirectories): Exercise these
7004 cases.
7006 2002-09-09 Akim Demaille <akim@epita.fr>
7008 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
7009 looking for a replacement file.
7010 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
7011 directory is relative.
7012 * doc/autoconf.texi (Generic Functions): Clarify the replacement
7013 directory definition.
7014 Reported by Andreas Schwab and Jim Meyering.
7016 2002-09-06 Akim Demaille <akim@epita.fr>
7018 * doc/autoconf.texi (Setting Output Variables): Clarify what
7019 precious variables are.
7020 Suggested by Pontus Skoeld.
7022 2002-09-05 Akim Demaille <akim@epita.fr>
7024 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7025 (ifnames, autoscan, autom4te): Since we don't only depend on
7026 configure.ac variables (such as VERSION etc.), but also on prefix
7027 and so forth, depend on Makefile, not configure.ac.
7028 Reported by Alexandre Duret-Lutz.
7029 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7031 2002-09-05 Kevin Ryde <user42@zip.com.au>
7033 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
7034 doesn't seem to be confined to ia64, just say "some versions".
7036 2002-09-04 Akim Demaille <akim@epita.fr>
7038 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
7039 Automake 1.6c.
7040 * Makefile.am (maintainer-clean-local): Remove.
7041 (MAINTAINERCLEANFILES): Remove COPYING.
7043 2002-09-03 Paul Eggert <eggert@twinsun.com>
7045 * doc/autoconf.texi (Configuration Commands): Remove obsolete
7046 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
7047 Brinkmann.
7049 2002-09-03 Akim Demaille <akim@epita.fr>
7051 * configure.ac: Bump to 2.53d.
7052 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
7053 as of today, on Automake's team suggestion.
7055 2002-09-03 Akim Demaille <akim@epita.fr>
7057 Version 2.53c.
7059 2002-09-02 Akim Demaille <akim@epita.fr>
7061 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
7062 SITE_MACRO_DIR.
7063 * configure.ac: Disable SITE_MACRO_DIR.
7065 2002-09-02 Jim Meyering <meyering@lucent.com>
7067 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
7068 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
7069 Also, tweak grammar: s/make sure to/be sure to/.
7071 2002-09-02 Paul Eggert <eggert@twinsun.com>
7073 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
7074 directory names are generally preferable to physical names.
7076 2002-09-02 Akim Demaille <akim@epita.fr>
7078 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7079 Reported by Raja R. Harinath.
7080 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7081 * bin/autoupdate.in: Use error instead of die.
7083 2002-09-01 Paul Eggert <eggert@twinsun.com>
7085 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7086 ordinary shell concatenation rather than echo+tr+sed command that
7087 runs afoul of a long-line-related sed bug in Solaris 8.
7089 * bin/autoheader.in (parse_args): --warning -> --warnings.
7091 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7092 stdout, as traditional "ls" does.
7093 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7094 _AC_COMPILER_EXEEXT_O): Likewise.
7095 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7097 * bin/autoconf.as: Add --prepend-include option. This patch was
7098 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7099 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7101 * bin/autoconf.in, configure: Regenerate.
7103 * doc/autoconf.texi (Special Shell Variables): Mention
7104 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7106 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7107 MAILPATH and set PS1, PS2, PS4 to default values, to work
7108 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7109 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7110 the Autoconf documentation specifies; fall back to "unset" only if
7111 this fails. Use a shell for-loop for this rather than an m4 loop,
7112 to shorten the output script.
7114 2002-08-30 Paul Eggert <eggert@twinsun.com>
7116 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7117 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7118 for the CDPATH problem. Document PWD.
7119 (Limitations of Builtins): Document the problem that "cd $foo" and
7120 "ls $foo" may refer to different directories in shells conforming
7121 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7122 example, since the old example is now out of date.
7124 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7125 FOO" and "ls FOO" talk about different directories; this catches
7126 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7127 spaghetti.
7129 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7130 of rolling our own unset.
7131 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7132 in practice we needn't worry about CDPATH if unset doesn't work.
7134 * Makefile.in, aclocal.m4, bin/Makefile.in,
7135 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7136 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7137 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7138 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7139 tests/Makefile.in: Regenerate with Automake 1.6.3.
7141 * config/config.guess, config/config.sub, config/mkinstalldirs:
7142 Update.
7144 * configure: Regenerate with self.
7146 2002-08-30 Kevin Ryde <user42@zip.com.au>
7148 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7149 default output.
7151 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7153 * bin/autom4te.in (Request::load): Correctly test for "do" read
7154 failure.
7156 2002-08-29 Akim Demaille <akim@epita.fr>
7158 * lib/Autom4te/General.pm (&xqx): New.
7159 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7160 hand, which is not portable.
7161 (&error): New.
7162 * bin/autom4te.in: Use them.
7163 Use &error instead of die.
7164 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7165 Adjust.
7167 2002-08-17 Paul Eggert <eggert@twinsun.com>
7169 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7170 default list of compilers to try, since it was long ago superseded
7171 by the ksh fc builtin. Suggested by Steven G. Johnson.
7173 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7175 * doc/autoconf.texi (Invoking autom4te): End the option table,
7176 fixing a bug introduced by the previous patch.
7177 (Limitations of Make): Add a 'target lookup' subentry in the
7178 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
7180 2002-07-29 Mark D. Roth <roth@feep.net>
7182 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
7183 options and use $AUTOM4TE_PATH.
7184 * doc/autoconf.texi: Remove documentation of autom4te
7185 --include-envvar and --site-macro-subdir options and document
7186 use of $AUTOM4TE_PATH.
7187 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
7188 arguments from each language section.
7190 2002-07-29 Paul Eggert <eggert@twinsun.com>
7192 * doc/install.texi: Include copyright symbol in copyright notice.
7194 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7195 Replace with:
7196 (AM_MAKEINFOFLAGS): New macro.
7197 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7198 * Makefile.am (INSTALL): Use the new macros.
7199 Use -o rather than --output, since "missing" does not grok --output.
7201 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7203 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7204 comments do not always work. Never trust the exit status of
7205 `make -k'.
7207 2002-07-24 Kevin Ryde <user42@zip.com.au>
7209 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7210 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
7212 2002-07-23 Paul Eggert <eggert@twinsun.com>
7214 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
7215 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
7216 apparently treats PATH="nonexistent" as if it contained ".".
7217 Bug reported by Stefan `Sec' Zehl.
7219 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7221 * doc/autoconf.texi (Limitations of Make): Mention the special
7222 handling of the obj/ directory by BSD make.

7238 2002-07-18 Akim Demaille <akim@epita.fr>
7240 Version 2.53b.
7242 2002-07-18 Akim Demaille <akim@epita.fr>
7244 * config/config.guess, config/config.sub: Update.
7246 2002-07-18 Akim Demaille <akim@epita.fr>
7248 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
7249 Automake's parts.

7252 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
7253 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
7255 2002-07-18 Akim Demaille <akim@epita.fr>,
7256 Alexandre Duret-Lutz <duret_g@epita.fr>
7258 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install

7264 description of the tarname default.
7266 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
7268 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
7269 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
7270 latter was not run.
7272 2002-07-17 Akim Demaille <akim@epita.fr>
7274 * lib/Autom4te/General.pm (find_file): Browse the directories in
7275 the order they are given.

7295 macro directory, remove note that include path directories are
7296 used in reverse order, and document --prepend-include option.
7297 * lib/autom4te.in: Use --prepend-include instead of --include.
7298 * tests/wrapsh.in: Use --prepend-include instead of --include.
7300 2002-07-17 Akim Demaille <akim@epita.fr>

7348 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
7350 * tests/mktests.sh: Use grep instead of fgrep, as per
7351 "Limitations of Builtins".

7355 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
7356 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
7357 so that we consistently test the just-built programs.

7360 2002-06-12 Paul Eggert <eggert@twinsun.com>
7362 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path

7366 * bin/autoreconf.in (autoconf, autoheader): Likewise.
7367 * bin/autoscan.in (autom4te): Likewise.
7368 * bin/autoupdate.in (autom4te): Likewise.
7370 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
7371 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
7372 on Solaris 2.5.1.
7374 2002-06-11 Andreas Schwab <schwab@suse.de>
7376 * doc/autoconf.texi: Add more dir entries.
7378 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
7380 * bin/autom4te.in ($cache): Don't define using `$me', the name
7381 of the cache should not depend on the name under which autom4te
7382 was installed.
7384 2002-06-07 Akim Demaille <akim@epita.fr>
7386 * tests/tools.at (autoconf: forbidden tokens, basic)
7387 (autoconf: forbidden tokens, exceptions): Adjust to the change of
7388 words in autom4te.in.
7390 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
7392 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use

7428 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
7430 2002-06-06 Paul Eggert <eggert@twinsun.com>
7432 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
7433 if ln doesn't work.
7434 * NEWS: Likewise.
7435 * doc/autoconf.texi (Configuration Links): Likewise.
7436 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
7438 2002-06-05 Paul Eggert <eggert@twinsun.com>
7440 * config/config.guess, config/config.sub, config/texinfo.tex:
7441 Update from masters.
7443 2002-05-29 Paul Eggert <eggert@twinsun.com>
7445 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
7446 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
7447 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):
7448 Likewise.

7458 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
7459 * doc/autoconf.texi (Particular Programs): Document them.
7460 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
7461 * NEWS: Likewise.
7463 2002-05-27 Paul Eggert <eggert@twinsun.com>
7465 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
7466 * NEWS, doc/autoconf.texi (Particular Types): Document it.
7467 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
7468 instead of AC_MBSTATE_T, which never existed.
7470 2002-05-23 Akim Demaille <akim@epita.fr>
7472 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
7473 version of Autoconf that is discussed.
7475 2002-05-22 Paul Eggert <eggert@twinsun.com>
7477 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
7478 from the default list of compilers to try. Suggested by
7479 Kate Hedstrom.
7480 * NEWS: Document the above.
7481 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
7483 2002-05-17 Paul Eggert <eggert@twinsun.com>
7485 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
7486 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
7487 This improves on an earlier suggestion by H. Peter Anvin.
7489 2002-05-16 Paul Eggert <eggert@twinsun.com>
7491 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7492 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7493 Both macros now accept an optional source-dir arg.
7494 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7496 * NEWS: Document this.
7497 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7499 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7500 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
7501 not for GNU extensions; this undoes part of the 2000-11-03 change,
7502 reverting to 2.13-compatible behavior.
7503 Add new optional argument DIR.
7504 (AC_FUNC_FNMATCH_GNU): New macro.
7506 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
7508 2002-05-08 Paul Eggert <eggert@twinsun.com>
7510 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7511 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7512 and it causes a 'test' syntax error if it fails.
7513 Bug reported by Stephen Gildea.
7515 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7516 If prototypes are supported, use them to check this at compile-time,
7517 instead of trying to check it at run-time. If we must do a run-time
7518 check, assume that setvbuf is standard when cross-compiling, as
7519 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7520 Bug reported by Paul D. Smith.
7522 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7523 argument specifying location of getloadavg.c. This removes a
7524 FIXME. This idea was taken from Jim Meyering's implementation in
7525 textutils.
7526 * doc/autoconf.texi (Particular Functions): Document this.
7527 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7528 that's what the code does; this fixes a bug reported by
7529 Paul D. Smith.
7531 2002-05-03 Akim Demaille <akim@epita.fr>
7533 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
7534 autopoint instead of gettextize.
7535 ($uses_alocal): Rename as...
7536 ($uses_aclocal): this.
7537 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7538 Suggested by Bruno Haible.
7540 2002-05-03 Akim Demaille <akim@epita.fr>
7542 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
7544 2002-04-29 Paul Eggert <eggert@twinsun.com>
7546 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7547 files to be 1 second older; just set them to be the same time.
7548 Also, sleep 1 second after the first aclocal, to work around
7549 problems with sub-second time stamps on the input files.
7551 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7553 * doc/autoconf.texi: Mention "set -e -x" lossage
7554 under node "Limitations of Builtins".
7556 2002-04-29 Akim Demaille <akim@epita.fr>
7558 * doc/install.texi: Better wording for setting variables when
7559 running configure.
7560 From Christian Cornelssen.
7562 2002-04-29 Akim Demaille <akim@epita.fr>
7564 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7565 of lack of $LINENO support, then the test will compare the $LINENO
7566 in testsuite vs. the lineno in the test file. This is wrong, of
7567 course.
7568 Be sure to protect it.
7569 Reported by Patrick Welche.
7571 2002-04-25 Akim Demaille <akim@epita.fr>
7573 * doc/autoconf.texi (Obsolete Macros): Typo.
7574 Reported by Vladimir Volovich.
7576 2002-04-25 Akim Demaille <akim@epita.fr>
7578 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7579 than some of the input files, hence, on the second run of aclocal,
7580 if some of its input are younger, make them older.
7581 Suggested by Paul Eggert.
7583 2002-04-25 Akim Demaille <akim@epita.fr>
7585 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
7586 Thanks to Paul Eggert.
7588 2002-04-25 Akim Demaille <akim@epita.fr>
7590 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
7591 and ac_subst_vars be sh variables containing the list of
7592 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7593 DEFAULT diversion.
7594 (_AC_INIT_PREPARE): Use them to log them.
7595 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7596 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7597 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7598 _AC_SUBST_FILES and _AC_SUBST_VARS.
7599 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
7601 2002-04-24 Akim Demaille <akim@epita.fr>
7603 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7604 autoheader, so that automake does not complain about a missing
7605 config.h.in that was to be created.
7607 2002-04-23 Akim Demaille <akim@epita.fr>
7609 * bin/autoheader.in (parse_args): --warning takes an argument.
7610 Fixes PR/220.
7612 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
7614 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
7615 and bb.out when cleaning up.
7617 2002-04-22 Akim Demaille <akim@epita.fr>
7619 Version 2.53a.
7621 2002-04-22 Akim Demaille <akim@epita.fr>
7623 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
7625 2002-04-22 Akim Demaille <akim@epita.fr>
7627 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
7628 comma.
7629 Reported by Gregory Giannoni.
7631 2002-04-22 Akim Demaille <akim@epita.fr>
7633 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
7634 Fixes false failures on Darwin.

7640 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

7659 Minor spelling and grammar fixes.
7661 * doc/autoconf.texi: Follow the outline suggested in the GNU
7662 Sample Texts sections of the Texinfo 4.2 manual. Most
7663 importantly, this makes sure that the copyright notices appear in
7664 all output formats. You probably need Texinfo 4.2 to generate
7665 the manual now.
7667 Fix some bugs when using "$@" when there might be zero positional
7668 arguments in cases where this matters.

7688 * tests/c.at: We can't have zero arguments, so remove workaround
7689 that is not portable to Zsh.
7691 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
7693 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
7694 from aclocal.m4 too.
7696 2002-04-12 Akim Demaille <akim@epita.fr>
7698 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
7700 2002-04-10 Akim Demaille <akim@epita.fr>
7702 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
7703 workaround for ${1+"$@"}.
7704 * doc/autoconf.texi (Shell Substitutions): Explain it.
7705 From Oliver Kiddle and Peter Stephenson.
7707 Have M4sh perform minimal shell sanitizing.
7709 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
7710 part into...
7711 (_AS_PREPARE): this new macro.
7712 (AS_PREPARE): New.
7713 (AS_INIT): Invoke AS_SHELL_SANITIZE.
7714 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
7716 Adjust Autoconf and Autotest.
7718 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
7719 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
7720 * lib/autotest/general.m4 (AT_INIT): Likewise.
7721 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7722 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
7723 AS_SHELL_SANITIZE.
7725 Use this M4sh to generate Autoconf's shell scripts.
7727 * tests/wrapsh.as: New, precursor of wrapsh.in.
7728 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
7729 on Autotest and M4sh.
7730 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
7731 (wrapsh.in): New target.
7732 * bin/autoconf.as: New, precursor of autoconf.in.
7733 (autoconf.in): New target.

7738 with indented comments in rules.
7740 2002-04-09 Andreas Schwab <schwab@suse.de>
7742 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
7743 ac_top_builddir when setting ac_abs_top_builddir.
7745 2002-04-06 Kevin Ryde <user42@zip.com.au>
7747 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
7748 (Portable Shell): Cross reference to Systemology.
7750 2002-04-05 Akim Demaille <akim@epita.fr>
7752 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
7753 directories when descending in a SUBDIRS.
7754 Reported by Ezra Peisach.
7756 2002-04-04 Andreas Schwab <schwab@suse.de>
7758 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
7759 contains no literal separators.
7761 2002-04-03 Akim Demaille <akim@epita.fr>
7763 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
7764 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
7765 Use dnl, not the KILL diversion.
7766 Extracted from...
7767 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
7768 (AC_CONFIG_LINKS): here.
7769 Adjust.
7770 Don't use the KILL diversion, as it kills spurious output, which
7771 results in failures being hidden.
7772 Use m4_defn where appropriate.
7773 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
7774 after the second argument.
7775 Use m4_defn.
7776 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
7777 syntax, as it is provided by M4sugar.
7778 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
7780 2002-04-03 Andreas Schwab <schwab@suse.de>

7786 aclocal.
7788 2002-04-03 Akim Demaille <akim@epita.fr>

7793 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
7794 (_AC_COMPILER_OBJEXT): Use them.
7795 Fixes Debian #138666.
7797 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
7799 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
7801 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
7802 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
7803 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
7804 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
7805 (AC_C_CONST): Same.

7817 2002-03-28 Kevin Ryde <user42@zip.com.au>
7819 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
7820 to avoid versions of HP C which don't allow that.
7822 2002-03-27 Paul Eggert <eggert@twinsun.com>
7824 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

7836 2002-03-25 Paul Eggert <eggert@twinsun.com>
7838 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
7839 as POSIX requires, as it doesn't work with Zsh.
7840 * doc/autoconf.texi (Assignments): Document the problem.
7842 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7844 * doc/autoconf.texi (Limitations of Make): Mention more issue
7845 about VPATH, overriding of macros in sub-makes, and handling of
7846 SHELL.
7848 2002-03-21 Paul Eggert <eggert@twinsun.com>
7850 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
7851 problem with here-document buffer boundaries.
7853 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
7854 when reinvoking the shell, to work around problems with installers
7855 who put strange things like "cd" commands in their environments.
7857 2002-03-19 Akim Demaille <akim@epita.fr>

7860 From Aaron Ucko.

7871 From Nishio Futoshi.
7873 2002-03-19 Akim Demaille <akim@epita.fr>
7875 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
7877 2002-03-18 Paul Eggert <eggert@twinsun.com>
7879 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
7880 (Limitations of Usual Tools): Add mkdir section.
7882 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
7883 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
7884 back on AS_DIRNAME to compute prefixes otherwise; this is
7885 roughly what mkinstalldirs does. That way, we need not have
7886 our own filename disassembler. The old disassembler did not
7887 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
7889 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
7890 Create at_test_all by a series of assignments,
7891 not by a single assignment of a long string. The latter causes ksh
7892 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
7893 presumably because of a buffer overrun.
7895 2002-03-14 Paul Eggert <eggert@twinsun.com>
7897 * lib/autotest/general.m4 (at_times_skip):
7898 Renamed from at_times. Now a boolean.
7899 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
7900 says 'times: not found'.
7902 2002-03-14 Akim Demaille <akim@epita.fr>
7904 * bin/autoreconf.in (&study_gettextize): New.
7905 (&autoreconf): Handle newest gettextize.

7927 m4_require.
7929 2002-03-11 Andreas Schwab <schwab@suse.de>
7931 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
7932 does not do it if --with-lispdir is given.
7934 2002-03-08 Akim Demaille <akim@epita.fr>
7936 Version 2.53.
7938 2002-03-08 Akim Demaille <akim@epita.fr>

7947 2002-03-08 Akim Demaille <akim@epita.fr>
7949 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
7950 aliases the actual variables, and modifications of the former
7951 affect the latter.
7953 2002-03-08 Akim Demaille <akim@epita.fr>
7955 * bin/autom4te.in (&handle_m4): Protect us from corrupted file

7986 parallel builds.
7988 2002-03-04 Akim Demaille <akim@epita.fr>
7990 * doc/autoconf.texi (Transforming Names): Equality between target
7991 and host is irrelevant.
7992 (Specifying Names, Canonicalizing): Remove all references to the
7993 backward compatibility hooks. Rather, collect them all into...
7994 (Hosts and Cross-Compilation): this new section.
7995 * doc/install.texi (System Type): Ditto.
7996 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
7997 that `--host' implies cross-compilation.
7999 2002-03-04 Akim Demaille <akim@epita.fr>
8001 * doc/autoconf.texi (Evaluation Macros): New.
8002 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8003 useless.
8004 (_m4_foreach): Define the variant with immediate evaluation so
8005 that it contains exactly the items, not an expression which
8006 evaluation is the current item.
8007 (m4_re_string, m4_re_word): Don't over quote them.
8009 2002-03-04 Akim Demaille <akim@epita.fr>
8011 Instead of having stacking `shift's evaluated at the end, let
8012 `foreach' loops immediately evaluate them.
8014 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8015 $*. This is the n-th time I change my mind, but hopefully this is
8016 the last...
8017 (m4_lquote): New.
8018 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8019 efficient.
8020 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8021 it was only a hack for m4_text_wrap.
8022 (m4_car2): Remove, replaced by...
8023 (m4_cdr): New.
8024 (_m4_foreach): Adjust.
8025 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8026 m4_bpatsubst for clarification.
8028 2002-03-04 Akim Demaille <akim@epita.fr>

8056 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
8057 From Akinori Musha.

8061 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
8062 translate \r\n to \n.

8096 2002-02-06 Akim Demaille <akim@epita.fr>
8098 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
8099 sure not to introduce newlines in at_groups.
8100 * lib/autotest/Makefile.am (autotest.m4f): Typo.
8102 2002-02-06 Akim Demaille <akim@epita.fr>
8104 * tests/torture.at (Configuring subdirectories): Skip if aclocal
8105 is not available.

8112 not unsigned long.
8113 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
8114 cross-compilers, too. This undoes some of the most recent change
8115 to this file.
8117 2002-02-05 Akim Demaille <akim@epita.fr>
8119 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
8120 to make sure they are up to date when `check' is run.

8131 2002-02-05 Akim Demaille <akim@epita.fr>
8133 Implement `autom4te --freeze'.
8135 * bin/autom4te.in (&freeze): New.
8136 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
8137 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
8139 2002-02-05 Akim Demaille <akim@epita.fr>
8141 * bin/autom4te.in (&parse_args): Implement `frozen files are
8142 optional are the sum of the previous files on the command line'.
8143 Also, pass `--reload-state=' on them, so...
8144 (handle_m4): don't.
8145 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
8146 (M4sh): Rely on M4sugar.
8147 (Autotest, M4sh, M4sugar): Use frozen files.
8149 2002-01-31 Akim Demaille <akim@epita.fr>
8151 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
8152 * doc/autoconf.texi (Initializing configure): Adjust.

8156 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
8157 alphanumeric to `-' instead of `_'.
8159 2002-01-30 Akim Demaille <akim@epita.fr>
8161 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
8162 for plain code, the other for cross-compilation code. The latter
8163 is now run with GCC only.

8171 change AC_INIT default values.
8173 2002-01-29 Akim Demaille <akim@epita.fr>
8175 * tests/torture.at (Configuring subdirectories): Use configure.in,
8176 so that aclocal 1.4 works.
8177 Reported by Alexandre Duret-Lutz and Larry Schmitt.
8179 2002-01-28 Akim Demaille <akim@epita.fr>
8181 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
8182 needs an argument.
8184 2002-01-28 Akim Demaille <akim@epita.fr>
8186 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8187 AUTOTEST_PATH *after* it was set.
8188 Don't put `.' in the PATH: the user should be precise and `./' if
8189 needed. In addition, given that the test suite does some `cd', if
8190 `.' is in the path, the `tested programs' sections will report
8191 programs found in the test suite's directory, while during the
8192 tests (performed in their own directory), these programs are no
8193 longer visible. In other words, the results is confusing and
8194 useless.
8195 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
8197 2002-01-24 Akim Demaille <akim@epita.fr>

8209 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
8210 Bourne. Use /bin/sh.
8211 From Andreas Buening.

8237 2002-01-21 Akim Demaille <akim@epita.fr>
8239 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
8240 message on invalid options.
8241 * bin/autom4te.in (parse_args): Don't use
8242 Autoconf::General::getopt with non valid options.
8244 2002-01-17 Jim Meyering <meyering@lucent.com>
8246 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
8247 $ac_cv_exeext so we don't use an old, invalid, cached value.
8249 2002-01-11 Akim Demaille <akim@epita.fr>
8251 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
8252 Meyering.

8261 package.m4, since is really depends upon configure.ac, not
8262 configure.
8263 * doc/autoconf.texi (testsuite Scripts): Adjust.
8264 * tests/Makefile.am (package.m4): New.
8265 EXTRA_DIST it since its a source.
8267 2002-01-06 Akim Demaille <akim@epita.fr>
8269 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
8270 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8271 and PACKAGE_BUGREPORT from here...
8272 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
8273 arguments.
8274 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
8275 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
8276 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
8277 * tests/tools.at (autoheader): Adjust.
8278 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
8280 2002-01-06 Akim Demaille <akim@epita.fr>

8299 2001-12-14 Akim Demaille <akim@epita.fr>
8301 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8302 trailing files, don't apply `-rf' to files which might not be
8303 created by configure (core, core.*, and *.core), but just `rm -f'.
8304 Suggested by Jonathan Kamens.
8306 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8308 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

8312 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8314 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

8342 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
8343 Remove $filepath, useless.
8344 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8345 variables, they are really part of the tokens.
8346 Split the input line on spaces and then look for tokens.
8347 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8348 because of `lex$U.$(OBJEXT)'.
8349 (&scan_files): Use "@list" instead of join.
8350 * doc/Makefile.am (CLEANFILES): Add *.fns.
8352 2001-11-26 Akim Demaille <akim@epita.fr>

8355 Remove, replaced by...

8357 In particular autoscan and autoheader want -I.
8358 * configure.ac: Adjust.

8413 spotted by Jim Meyering.
8415 2001-11-16 Paul Eggert <eggert@twinsun.com>
8417 This patch implements a `long double' suggestion by Oliver Kiddle.
8419 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8420 static, to catch errors if the value isn't known at compile-time
8421 and the compiler supports dynamic arrays. Change its name from
8422 `_array_' to `test_array' to avoid potential name clashes.
8423 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8424 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8425 better than double. Catch a bug in GCC 2.95.2 x86.
8426 * doc/autoconf.texi (C Compiler): Document the above.
8427 * NEWS: Likewise.
8429 2001-11-13 Akim Demaille <akim@epita.fr>
8431 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8432 hand.
8433 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8435 2001-11-13 Akim Demaille <akim@epita.fr>
8437 * lib/autotest/general.m4 (AT_INIT): After having run the test
8438 group, go back to the initial directory, not to at_suite_dir.
8440 2001-11-13 Akim Demaille <akim@epita.fr>
8442 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8443 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8444 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8445 option.
8446 (AT_CHECK_CONFIGURE): Use absolute paths.
8447 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8448 The problem is still the old one: there is no means in M4 (that I
8449 know about) to create a defining macro, because there is no means
8450 to create `$1' etc., therefore, the defining macro ``swallows''
8451 all the arguments meant to the defined macro.
8453 2001-11-13 Akim Demaille <akim@epita.fr>
8455 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8456 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8457 configure.ac.
8458 * tests/aclocal.m4: Remove, as it is no longer used.
8460 2001-11-13 Akim Demaille <akim@epita.fr>
8462 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8463 variable names when referring to a single test group, or to
8464 `suite' when referring to the whole test suite.
8465 `at_last_test' is removed: m4 compute at_format itself.
8466 (at_stdout, at_stder1, at_stderr): New variables.
8467 (AT_CHECK): Use them.
8469 2001-11-13 Akim Demaille <akim@epita.fr>
8471 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8472 in PATH.
8473 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8474 Do it as soon as a test fails, don't wait till the end of the test
8475 suite.
8476 Don't remove $as_me.[0-9]*, since these files no longer exist.
8478 2001-11-13 Akim Demaille <akim@epita.fr>
8480 * tests/tools.at: Use absolute paths, since we are no longer run
8481 in place.
8483 2001-11-13 Akim Demaille <akim@epita.fr>
8485 Now that tests are running in their own private dir, there is no
8486 need to list the files to remove at the end of tests groups.
8488 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8489 (AT_data_files, at_data_files): Remove.
8490 (AT_CLEANUP, AT_DATA): Simplify.
8491 (AT_INIT): Adjust.
8492 Remove the group dir if !debug && !failed.
8493 * tests/atspecific.m4: Adjust.
8495 2001-11-13 Akim Demaille <akim@epita.fr>
8497 Start a new layout for Autotest: `testsuite' creates
8498 `testsuite.dir' in which the at-check-line etc. files are to be
8499 found, and `testsuite.dir/003' where the test group 3 is run.
8501 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8502 at_check_line_file, at_format, at_test_normalized, at_group_dir
8503 are new variables.
8504 Create the directories.
8505 Use absolute paths for at- files.
8506 (AT_CHECK): Adjust.
8508 2001-11-11 Michael Matz <matz@kde.org>
8510 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8511 (m4_car2): New.
8512 (m4_car): Properly quote arguments.
8514 2001-11-13 Akim Demaille <akim@epita.fr>
8516 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8517 with stricter rules on LIBOBJS.
8519 2001-11-12 Paul Eggert <eggert@twinsun.com>
8521 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8522 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8523 __PROTOTYPES too.
8525 2001-11-12 Akim Demaille <akim@epita.fr>
8527 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8529 2001-11-12 Akim Demaille <akim@epita.fr>
8531 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8532 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8533 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8534 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8535 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8536 specify to what the macro should be defined (typically to 1).
8538 2001-11-12 Akim Demaille <akim@epita.fr>
8540 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8541 From Jim Meyering.
8543 2001-11-12 Akim Demaille <akim@epita.fr>
8545 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8546 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8547 definition used by Automake where LEX is +/- "${missing} lex" and
8548 `missing' itself contains variables.
8550 2001-11-12 Akim Demaille <akim@epita.fr>
8552 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8553 Now that M4sh pushes BODY, the comments were output at the end of
8554 the test suites.
8556 2001-11-08 Akim Demaille <akim@epita.fr>
8558 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8559 that we can trace macros from aclocal.m4.
8560 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8561 obsoleted, and redirect to the former anyway.
8562 Reported by Ralf Corsepius.
8564 2001-11-08 Akim Demaille <akim@epita.fr>
8566 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
8567 processed only if present.
8568 * tests/torture.at (Configuring subdirectories): Use autoreconf
8569 instead of successive calls to autoconf.
8570 Add a nonexistent subdirectory to exercise the patch above.
8571 Reported by Ralf Corsepius.
8573 2001-11-08 Kevin Ryde <user42@zip.com.au>
8575 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
8576 doesn't accept .S files.
8578 2001-11-07 Akim Demaille <akim@epita.fr>
8580 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
8581 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
8582 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
8583 * bin/autom4te.in (warn_forbidden): New.
8584 (handle_output): Use it.
8585 Read m4_pattern_forbid with messages.
8587 2001-11-05 Akim Demaille <akim@epita.fr>
8589 * bin/autom4te.in (--normalize): Remove.
8590 * lib/autom4te.in: Adjust.
8592 2001-11-05 Akim Demaille <akim@epita.fr>
8594 * tests/Makefile.am (testsuite): Rename this target as...
8595 ($(TESTSUITE)): this.
8596 From Nicolas Joly.
8598 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
8600 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
8601 the --prefix option, also remove it's argument.
8603 2001-11-05 Akim Demaille <akim@epita.fr>
8605 * doc/autoconf.texi (testsuite Invocation): Update.
8606 (Writing testsuite.at): Update.
8608 2001-11-03 Akim Demaille <akim@epita.fr>
8610 * doc/autoconf.texi: s/@code/@command/ where appropriate.
8612 2001-11-03 Akim Demaille <akim@epita.fr>
8614 * lib/Autom4te/General.pm: (&catfile, &canonfile)
8615 (&file_name_is_absolute): New, wrappers around routines from
8616 File::Spec.
8617 Use and export them.
8618 (&find_configure_ac): Optionally take a directory where to look at.
8619 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
8620 the arguments.
8621 Default @ARGV to `.', not find_configure_ac.
8622 (&autoreconf): Argument is a directory.
8623 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
8624 * doc/autoconf.texi (autoreconf Invocation): Update.
8626 2001-11-03 Akim Demaille <akim@epita.fr>
8628 * lib/Autom4te/General.pm (@export_vars, @export_subs)
8629 (@export_forward_subs): New.
8630 Add basename, dirname, and fileparse.
8631 (@EXPORT): Adjust.
8632 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8633 Don't look for aclocal flags if we already know aclocal is not
8634 used.
8635 Move aclocal.m4t only if it exists.
8636 Reported by Ezra Peisach.
8638 2001-11-03 Akim Demaille <akim@epita.fr>
8640 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8641 passed on command line, defaulting to ./configure.ac if present.
8642 (&maybe_autoreconf, File::Find): Remove, unused.
8643 (&autoreconf): If autoconf is not used, don't try to trace.
8645 2001-11-02 Akim Demaille <akim@epita.fr>
8647 * configure.ac: Bump to 2.52g.
8649 2001-11-02 Akim Demaille <akim@epita.fr>
8651 Version 2.52f.
8653 2001-11-02 Akim Demaille <akim@epita.fr>
8655 * config/config.guess, config/config.sub, doc/standards.texi:
8656 * config/lispdir.m4: Update from masters.
8657 * configure.ac: Bump to 2.52f.
8659 2001-11-02 Akim Demaille <akim@epita.fr>
8661 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8662 Don't run aclocal when aclocal.m4 is not from aclocal.
8663 From Ezra Peisach.
8664 Don't run libtoolize and gettextize if --install is not given.
8666 2001-11-01 Paul Eggert <eggert@twinsun.com>
8668 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8669 be invoked before _AS_LINENO_PREPARE.
8670 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
8671 than character ranges.
8673 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
8674 invoking AS_BASENAME. Set the locale variables to 'C' if
8675 possible, as POSIX requires this to get the traditional
8676 behavior.
8677 * doc/autoconf.texi (Special Shell Variables): Describe the above.
8679 2001-10-31 Paul Eggert <eggert@twinsun.com>
8681 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
8682 with {}, as that triggers a bug in Bash 2.05.
8684 (_AS_LINENO_PREPARE): Use Sed rather than
8685 Awk. Fix the sed prepass to work even if there are multiple
8686 instances of $LINENO on the same line. Do not substitute for
8687 other variables like $LINENOT. Do not check file dates; such a
8688 check is unreliable on sufficiently fast machines, and removing
8689 the check makes the code simpler and more reliable. Check for
8690 output and chmod failures.
8692 * doc/autoconf.texi (Special Shell Variables): Document
8693 the above.
8695 2001-10-31 Akim Demaille <akim@epita.fr>
8697 * tests/Makefile.am (atconfig): Remove this target, Automake
8698 handles it now.
8700 2001-10-31 Akim Demaille <akim@epita.fr>
8702 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
8703 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
8704 provided, while it is optional.
8705 * configure.ac: Adjust.
8707 2001-10-26 Paul Eggert <eggert@twinsun.com>
8709 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
8710 lib/Autom4te/Struct.pm:
8711 Require Perl 5.005_03 instead of just 5.005, as some tests fail
8712 with 5.005_02.
8714 * doc/autoconf.texi (Special Shell Variables): Document some
8715 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
8717 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
8718 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
8719 eval $LINENO is not portable in practice.
8721 2001-10-24 Akim Demaille <akim@epita.fr>
8723 * lib/Autom4te/General.pm (backname): New.
8725 2001-10-24 Akim Demaille <akim@epita.fr>
8727 * m4/: Remove, merged into...
8728 * config/: here.
8730 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
8732 * doc/autoconf.texi (Shellology): Mention the problems with bash
8733 2.05's use of ANSI quoting in its `set' builtin.
8735 2001-10-22 Paul Eggert <eggert@twinsun.com>
8737 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
8738 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
8739 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
8740 POSIX decided to standardize on the int flavor of strerror_r.
8741 Always do char* test, as there's no reason not to.
8742 Assign to a char* var, to catch strerror_r that returns int*.
8744 * doc/autoconf.texi (Particular Functions):
8745 Document the above changes. Also, document the fact that
8746 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
8748 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
8750 2001-10-20 Akim Demaille <akim@epita.fr>
8752 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
8753 the executable was missing from the log.
8755 2001-10-20 Akim Demaille <akim@epita.fr>
8757 * lib/Autom4te/General.pm (&update_file): If destination is
8758 unchanged, remove the source.
8759 (&up_to_date_p): Don't be verbose, be debug.
8760 * bin/autoreconf.in: No longer support --m4dir.
8761 (&autoreconf): Display the full path of the configure.ac we are
8762 studying.
8763 Trace it only once.
8764 Be sure to honor --force with gettextize.
8765 Always run aclocal.
8766 * doc/autoconf.texi: Adjust.
8768 2001-10-20 Akim Demaille <akim@epita.fr>
8770 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
8771 Remove, dead.
8772 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
8773 `intl' is already present, as it refuses unless --force.
8774 (&parse_args): Use -I, --include instead of the old Autoconf
8775 options.
8776 ($localdir, $autoconf_dir): Remove.
8777 (@include): New.
8778 (&maybe_autoreconf): New, to preserve $_ for File::Find.
8780 2001-10-19 Jens Petersen <petersen@redhat.com>
8782 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
8783 * doc/autoconf.texi (Particular Programs): Likewise.
8785 2001-10-19 Akim Demaille <akim@epita.fr>
8787 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
8788 file in @configure_input@.
8789 Don't mention `automatically' in addition to `generated'.
8790 * tests/torture.at (#define header templates): Adjust.
8792 2001-10-19 Akim Demaille <akim@epita.fr>
8794 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
8795 comment, explain how to install automatic mode selection.
8796 From Russ Allbery.
8798 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
8800 * bin/autoreconf.in (autoreconf): Display the path to the
8801 configure.ac being studied.
8803 2001-10-18 Paul Eggert <eggert@twinsun.com>
8805 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
8806 long, to work around a bug in the HP C compiler version HP92453-01
8807 B.11.11.23709.GP.
8809 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
8810 (AS_BASENAME_EXPR): New macro.
8811 (AS_BASENAME_SED): Do not assume GNU sed semantics.
8812 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
8813 and fall back on 'sed' only if the other two fail. This makes
8814 AS_BASENAME act more like AS_DIRNAME.
8815 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
8816 contains white space.
8817 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
8818 Use AS_DIRNAME, since I think it's now DOS-friendly.
8819 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
8820 Allow "dirname //FOO" to return either / or //, as POSIX allows
8821 either behavior.
8823 2001-10-10 Akim Demaille <akim@epita.fr>
8825 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
8826 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
8827 From Eric Sharkey.
8829 2001-10-10 Akim Demaille <akim@epita.fr>
8831 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
8832 m4_define, since...
8833 (_AS_ECHO_N): AS_REQUIREs it.
8835 2001-10-10 Akim Demaille <akim@epita.fr>
8837 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)

8855 (Autoconf): Use it.
8857 2001-10-08 Akim Demaille <akim@epita.fr>
8859 * bin/autoreconf.in (autoreconf): Run libtoolize when appropriate.
8861 2001-10-08 Akim Demaille <akim@epita.fr>

8874 2001-10-08 Akim Demaille <akim@epita.fr>
8876 * bin/autoreconf.in: Rewrite in Perl.
8877 * configure.ac: Adjust.
8878 * lib/Autom4te/General.pm (&up_to_date_p): New.
8879 * bin/autom4te.in (&up_to_date_p): Use it.
8880 Rename as...

8923 (AC_REQUIRE, AC_PROVIDE, AC_PROVIDE_IFELSE): Be exact copy of the
8924 M4sugar peer, i.e., drop the `AC_PROVIDE_$1' broken marker.
8926 2001-10-08 Akim Demaille <akim@epita.fr>
8928 Use `add-log-current-defun-function' for ChangeLog creation.
8929 Suggested by Tom Tromey.
8931 * lib/emacs/autotest-mode.el (autotest-mode-map): New.
8932 (autotest-mode): Adjust.

8957 CONFIG_SHELL defaults to a shell that supports LINENO if available.
8959 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
8960 shell does not support LINENO, and if CONFIG_SHELL is unset or
8961 empty, and if we can find a shell that does support LINENO,
8962 then set CONFIG_SHELL to that shell and then re-execute
8963 ourselves with CONFIG_SHELL.
8965 2001-10-05 Paul Eggert <eggert@twinsun.com>
8967 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
8968 doesn't exist. Remove *.tmp, as a .tmp file is created during the
8969 build of $(TESTSUITE).
8971 2001-10-05 Akim Demaille <akim@epita.fr>
8973 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

8993 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): New, extracted from...
8994 (AS_SHELL_SANITIZE): here. Use it.

8996 From Paul Eggert.
8998 2001-10-04 Akim Demaille <akim@epita.fr>
9000 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable
9001 combination of Awk and sed to replace $LINENO.
9003 2001-10-02 Paul Eggert <eggert@twinsun.com>
9005 * doc/autoconf.texi (Limitations of Builtins): You can't use
9006 "source"; it's not portable. Remove confusing and
9007 somewhat-incorrect example involving "." and "/".
9009 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
9010 compatibility with POSIX shells.
9012 2001-10-02 Akim Demaille <akim@epita.fr>
9014 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
9015 instead of exec'ing to preserve $0 and $@.
9017 2001-10-01 Akim Demaille <akim@epita.fr>

9038 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
9039 Don't use nested parenthesization. This patch was originally
9040 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
9041 but somehow it didn't get incorporated then.
9042 * doc/autoconf.texi (Limitations of Usual Tools):
9043 Clarify remark about sed and nested parenthesization.

9046 Report an error if the size cannot be determined even though
9047 the type exists.
9048 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9049 Check for `expr' arithmetic overflow, and for compilation failure,
9050 and invoke a new argument $4 if either is discovered.
9051 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
9052 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
9054 2001-09-28 Akim Demaille <akim@epita.fr>

9081 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC): Move to...
9082 * tests/c.at (Extensions, C keywords)
9083 (Broken/missing compilers, AC_PROG_CPP with warnings)
9084 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
9085 (AC_PROG_CPP requires AC_PROG_CC): here and...
9086 * tests/fortran.at (GNU Fortran 77): there.
9087 * doc/autoconf.texi (autoconf Invocation): Fix the example:
9088 AC_TRY_RUN is about compilation, not shell commands.
9089 (Test Programs): AC_TRY_RUN works as used to be advertised.
9091 2001-09-27 Akim Demaille <akim@epita.fr>
9093 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
9094 Raja R Harinath:
9095 Be sure to detect when $LINENO always returns the same value.
9096 Look for the original script, basename($0) is certainly not
9097 enough.
9098 Pass the CLI arguments to `$as_me.lineno'.
9100 2001-09-25 Akim Demaille <akim@epita.fr>
9102 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.
9103 Be sure the close and reopen the LOG fd before and after using tee

9107 2001-09-23 Akim Demaille <akim@epita.fr>
9109 * bin/autom4te.in (parse_args): There can be several invocations
9110 of --language now.
9112 2001-09-23 Akim Demaille <akim@epita.fr>
9114 * doc/autoconf.texi (Top): Wrap in @ifnottex.
9116 2001-09-23 Akim Demaille <akim@epita.fr>
9118 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
9119 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
9120 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
9121 builddir, buildpath, top_builddir, and top_buildpath.
9122 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
9123 the current directory.
9124 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir

9126 Skip nonexistent dirs.
9127 * doc/autoconf.texi (Preset Output Variables): Document these
9128 variables.
9130 * lib/autotest/general.m4: Do not reset AT_victims.
9131 Don't compute at_srcdir nor at_top_srcdir.
9133 * tests/tools.at: Hence use top_srcdir.
9135 * tests/Makefile.am, tests/autoconf, tests/autoheader,
9136 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
9137 Remove.

9140 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
9141 * configure.ac: Build the position independent wrappers.
9143 * man/Makefile.am: Now that test wrappers are position

9148 * doc/autoconf.texi (Common Shell Constructs): Rename as...
9149 (Programming in M4sh): this.

9177 (Autoconf): Adjust.
9179 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
9181 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,
9182 * m4/install-sh.m4, m4/missing.m4, m4/sanity.m4, m4/strip.m4: Updated
9183 to match current versions from CVS Automake.
9185 2001-09-23 Alexandre Duret-Lutz <duret_g@epita.fr>
9187 * doc/autoconf.texi (Special Shell Variables): Add pdksh output
9188 for $LINENO.
9190 2001-09-22 Akim Demaille <akim@epita.fr>
9192 * lib/autoconf/autotest.m4: Create `package.m4'.
9193 * tests/Makefile.am (package.m4): Remove.
9195 2001-09-22 Akim Demaille <akim@epita.fr>
9197 Rely on `$LINENO' when possible instead of `__oline__'.
9199 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
9200 `$LINENO' support replacement when not supported.
9201 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
9202 them explicitly to be sure they are not output before this section
9203 (via m4_require). Cosmetic only.
9204 * lib/autoconf/c.m4, lib/autoconf/general.m4,
9205 * lib/autoconf/programs.m4: Replace all the occurrences of
9206 `__oline__' with `$LINENO'.
9207 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
9209 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
9211 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
9212 character (u: -> ue) in a code comment.
9213 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
9214 it works.
9216 2001-09-21 Akim Demaille <akim@epita.fr>
9218 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
9219 Suggested by Jim Meyering.
9221 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9223 * lib/autoconf/programs.m4: Use extensions listed in

9228 * lib/autoconf/general.m4: Fix a small Englisho.

9230 setting up ac_dir_suffix and ac_top_builddir.
9231 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
9233 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9235 * doc/autoconf.texi (File System Conventions): Clarify the use of
9236 PATH_SEPARATOR.
9237 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
9238 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
9239 be used instead of ':'.
9240 * lib/autotest/general.m4: Replace occurrences of ':' in
9241 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
9243 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9245 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
9246 arguments. Fixed a typo.
9248 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9250 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
9251 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
9253 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9255 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
9256 * bin/autoupdate.in: Ditto.
9257 * bin/autoheader.in: Reworded a few comments.
9258 * bin/autoconf.in: Reworded help text for a few options.

9262 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9264 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
9265 already have $file). Set output files to binary mode (helps avoid
9266 CR issues on DOSish systems).
9268 2001-09-19 Akim Demaille <akim@epita.fr>
9270 * lib/autotest/general.m4: Englishoes.
9271 From Tim Van Holder and Alexey Mahotkin.
9273 2001-09-18 Paul Eggert <eggert@twinsun.com>
9275 * doc/autoconf.texi (Common Shell Constructs): New node,
9276 documenting AS_DIRNAME.
9277 (Limitations of Usual Tools): Refer to it when discussing dirname.
9278 Also, update discussion of POSIX standard to reflect latest draft.
9280 * lib/autoconf/c.m4:
9281 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9283 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9284 Do not pass a first argument with leading '-'
9285 to expr, by parenthesizing initial integers that might be negative.
9287 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9288 now merely checks whether it is an error to pass an argument
9289 to getpgrp.
9291 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9292 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9293 whether it is a (compile-time) error to pass an argument to
9294 getpgrp. This simpler test supports the revised documentation,
9295 and is all that AC_FUNC_GETPGRP's users really need.
9297 2001-09-18 Akim Demaille <akim@epita.fr>
9299 * doc/autoconf.texi (Limitations of Make) <$<>: New.
9301 2001-09-18 Akim Demaille <akim@epita.fr>

9305 * lib/autotest/general.m4 (AT_INIT): Adjust.
9307 2001-09-18 Paul Wagland <paul@wagland.net>
9309 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
9310 correctly.
9311 Add test for AS_BASENAME.
9312 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9313 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9314 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9315 * tests/base.at: Fixed the expected responses. The old ones were
9316 one line out...
9317 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9318 the documentation claims it should (and how it behaved in 2.13).
9320 2001-09-18 Akim Demaille <akim@epita.fr>
9322 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9323 the AC_CONFIG_COMMANDS invocation.
9324 This also solves the name clash problems.
9325 Don't set the package's ID.
9326 * lib/m4sugar/Makefile.am (version.m4): Revamp.
9327 No longer to be shipped.
9328 (version.in): Remove.
9329 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
9330 * lib/autoconf/status.m4: Adjust.
9331 Use `m4_PACKAGE_STRING'.
9332 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9333 the only optional argument is the name of the test suite.
9334 Expect `package.m4' to define the package signature.
9335 * lib/autom4te.in (Autotest): Add `package.m4?'.
9336 * tests/Makefile.am (package.m4): New.
9337 * tests/suite.at: ifnames is a victim.
9339 2001-09-18 Akim Demaille <akim@epita.fr>
9341 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
9342 AC_LIBSOURCE, AC_CONFIG_FILES.
9343 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
9344 program version string doesn't match the package's.
9345 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
9346 after `(cached)'.
9348 2001-09-17 Paul Eggert <eggert@twinsun.com>
9350 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9351 Allow expression to return any value that can fit into unsigned long
9352 (not int, as before). Check for output errors.
9354 2001-09-17 Bruno Haible <haible@ilog.fr>
9356 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9357 Always include <stdio.h> and <stdlib.h>. Evaluate
9358 the expression in an extra function before these includes. Call
9359 fprintf "%d" only after ensuring the argument is of type 'int'.
9360 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
9362 2001-09-17 Paul Eggert <eggert@twinsun.com>
9364 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9365 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9366 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9367 when they don't exist.
9369 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,

9374 version with the version used by fileutils 4.1, except use

9532 2001-09-05 Akim Demaille <akim@epita.fr>
9534 Be ready to handle filenames as stupid as `dnl.at', for if even
9535 the maintainer is dumb enough to do that...
9537 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
9538 excellence in M4 quotation: consider `__file__' is active.
9540 And BTW, when invoking m4, pass the --include in the right order:
9541 the wrong one.
9543 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
9544 4m.
9546 2001-09-05 Akim Demaille <akim@epita.fr>

9566 2001-09-05 Akim Demaille <akim@epita.fr>

9571 New, extracted from main.
9572 Use IO::File wherever possible.
9573 (input.m4): Be constant, use -I instead of hard coding $tmp.
9574 Therefore be a quoted heredoc.
9575 Don't invoke `_au_disable', since ac was not loaded, but just
9576 `unm4.m4'.
9578 2001-08-31 Akim Demaille <akim@epita.fr>
9580 Version 2.52d.

9603 2001-08-31 Akim Demaille <akim@epita.fr>
9605 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
9606 (testsuite Scripts): There is no such thing as `atconfig.in'.
9607 And actually one diagram is missing: test suite runtime.
9609 2001-08-31 Akim Demaille <akim@epita.fr>
9611 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
9612 inverse order.
9614 2001-08-31 Akim Demaille <akim@epita.fr>
9616 * bin/autoupdate.in (@include): `installcheck' revealed the path
9617 to m4sugar was lacking!
9619 2001-08-31 Akim Demaille <akim@epita.fr>
9621 * man/Makefile.am (.x.1): We really have to pass
9622 autom4te_perllibdir.
9624 2001-08-31 Akim Demaille <akim@epita.fr>
9626 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

9628 run is stupid.
9630 2001-08-31 Akim Demaille <akim@epita.fr>
9632 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
9633 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
9634 Use directly autom4te, not autoconf.

9658 `print $out' doesn't print `$_' but `$out'.
9659 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
9660 (autoheader): Pass --force since the test suite goes too fast for
9661 the time stamps.
9662 Adjust to the new autoheader messages.
9664 2001-08-31 Akim Demaille <akim@epita.fr>

9675 * bin/autoupdate.in, bin/autoheader.in: Adjust.
9676 Drop AC_MACRODIR dead for real.
9677 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
9678 `autoheader: `config.hin' is created'.
9679 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
9681 2001-08-31 Akim Demaille <akim@epita.fr>
9683 * bin/autoheader.in: Rewrite in Perl.

9686 2001-08-31 Akim Demaille <akim@epita.fr>

9689 Map --localdir, --autoconf-dir onto it.
9690 Forward autom4te's options instead of interpreting them.
9691 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
9692 There is no such envvar since the inception of autom4te.cfg.
9693 * bin/autom4te.in (&parse_args): Uniquify `@include'.

9698 2001-08-31 Akim Demaille <akim@epita.fr>

9701 * bin/autom4te.in (&find_file): Support `FILE?' standing for

9704 (&parse_args): Adjust.
9705 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
9707 2001-08-31 Akim Demaille <akim@epita.fr>

9710 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
9711 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
9712 installed peer executables, only PATH is allowed to resolve it.
9713 Pass `autoconf_dir' via options, not via invisible envvars.
9714 * lib/Autom4te/General.pm (&find_peer): Remove.
9715 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
9716 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
9717 * man/Makefile.am: Let help2man rely on PATH instead of trying to
9718 find the executables for it.
9719 * tests/Makefile.am: Major cleanup. Too lazy to document...
9720 * tests/atlocal.in: Remove all the obscure envvar manipulations.
9721 We only need PERL.
9722 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
9723 indeed related to running the test suite, while passing
9724 --autoconf-dir and others is related to running non installed
9725 Autoconf executables. So don't do that, leave it to...
9726 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
9727 * tests/autoscan: New.
9728 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

9745 Suggested by Paul Eggert.
9747 2001-08-29 Akim Demaille <akim@epita.fr>
9749 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
9750 download in a tmp dir.
9752 2001-08-29 Akim Demaille <akim@epita.fr>
9754 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

10291 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10293 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
10294 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
10295 * doc/autoconf.texi (C Compiler Characteristics): Update
10296 documentation for AC_C_BIGENDIAN.
10298 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10300 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
10301 magic values from an object file when cross-compiling.
10302 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
10304 2001-08-10 Akim Demaille <akim@epita.fr>
10306 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10307 effects.
10308 Suggested by Russ Allbery.
10310 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10312 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10313 current $prefix to the sub-configures.
10315 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10317 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10318 extension (needed on BeOS). Reported by Guido van Rossum.
10320 2001-08-09 Akim Demaille <akim@epita.fr>
10322 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10324 2001-08-07 Akim Demaille <akim@epita.fr>
10326 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10327 removed.
10328 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10329 No need to remove the files before and after the each test, before
10330 each test and at the end of the suite is enough.
10331 Display only the children `times', not the shell's.
10332 If the test failed or was skipped, at-times is not available.
10334 2001-08-07 Akim Demaille <akim@epita.fr>
10336 Always produce testsuite.log, including when there are no
10337 failures. This helps getting information on skipped tests, and
10338 duration of the tests. Err, implement the latter btw.
10340 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10341 Dump information on the first run of each test.
10342 (AT_CLEANUP): Create `at-times' containing the duration of the
10343 test group.
10345 2001-08-07 Akim Demaille <akim@epita.fr>
10347 The use of `dumpstat' revealed that `len' was used although it
10348 should not. m4_text_wrap was using it, but in the Autoconf world
10349 where it is legal. Hence (i) test M4sh in its own world, not
10350 Autoconf's, and (ii), ahem, fix the bug :)
10352 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10353 does not like `' instead of [].
10354 (AT_INIT): Forbid `^_?AT_'.
10355 And don't output such tokens.
10356 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10357 `script.as', and `autom4te.cache'.
10358 Remove `empty' and `macro' which are no longer used.
10359 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10360 * tests/m4sugar.at: Use it.
10361 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
10363 2001-08-07 Akim Demaille <akim@epita.fr>
10365 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
10367 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
10369 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
10371 2001-08-04 Akim Demaille <akim@epita.fr>
10373 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
10374 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
10375 AC_TRY_LINK.
10376 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
10377 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
10378 (AC_F77_MAIN): Likewise.
10380 2001-08-04 Akim Demaille <akim@epita.fr>
10382 Don't rely on M4sugar outputting the patterns in files, since we
10383 might process the output _without_ running m4, hence without these
10384 files.
10386 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
10387 * bin/autom4te.in (@Request::includes): Remove, unused.
10388 (@Request::source): Rename as...
10389 (@Request::input): this.
10390 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
10391 (&handle_output): Fetch the patterns from the traces.
10392 `$forbidden' and `$allowed' are constant: use m//o.
10393 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
10394 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
10396 2001-08-04 Akim Demaille <akim@epita.fr>
10398 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
10399 autoconf', i.e., in addition to caching traces, cache the output.
10401 * bin/autom4te.in (Request::cache): Rename as...
10402 (Request::id): this.
10403 ($cache, $icache, $tcache, $ocache): New.
10404 (&handle_m4): Save M4 output in the cache instead of $tmp.
10405 (&handle_output): Adjust.
10406 (&up_to_date_p): Check that the output cache is up to date too.
10407 (top level): Run `&handle_m4' iff force or the cache is invalid.
10408 Run `&handle_output' if the output cache is more recent.
10410 2001-08-04 Akim Demaille <akim@epita.fr>
10412 * bin/autom4te.in ($force): New.
10413 (&parse_args, &print_usage): -f, --force is a new option.
10414 (&handle_output): CPP directives might have spaces after `#'.
10415 (&parse_args): The first file only can be frozen.
10417 2001-08-04 Akim Demaille <akim@epita.fr>
10419 Don't let autom4te compute the `include' traces several times:
10420 first check that the trace cache file is up to date, and then
10421 compare its timestamp with that of the output.
10423 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
10424 the preamble. Don't require 5.005 as Autom4te::General does it,
10425 and better yet (use `use', not `require'!).
10426 * lib/Autom4te/Struct.pm: Rename the last occurrences of
10427 Class::Struct as Autom4te::Struct.
10428 * lib/Autom4te/General.pm (File::stat): Use it.
10429 (&mtime): New, export it.
10430 * bin/autom4te.in: Use it.
10431 Declare `$req' is invalid if it is outdated.
10432 Don't declare it valid before saving it if something went wrong.
10434 2001-08-04 Akim Demaille <akim@epita.fr>
10436 Autom4te shall not encode Autoconf data, and preselecting traces
10437 must be proposed to the users.
10439 * bin/autom4te.in (@required_trace): Remove.
10440 (@preselect): New.
10441 (&parse_args, &print_usage): -p, --preselect is a new option.
10442 (&up_to_date_p): Adjust.
10443 * bin/autoconf.in: Preselect some Autoconf macros.
10445 2001-08-04 Akim Demaille <akim@epita.fr>
10447 * tests/tools.at (autoconf --trace: user macros): Check traces on
10448 macros invoked without arguments, and macros invoked with multiple
10449 lines arguments.
10451 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
10453 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
10454 arguments.
10456 2001-08-03 Akim Demaille <akim@epita.fr>
10458 * bin/autoconf.in ($@): Work around the usual sh bug.
10459 From Nicolas Joly.
10461 2001-08-03 Akim Demaille <akim@epita.fr>
10463 Clean up the handling of the M4 builtins tracing exception.
10465 * bin/autom4te.in (Request::request): Don't complete M4 builtins
10466 trace requests.
10467 (@m4_builtins): Rename as...
10468 (@m4_builtin): this.
10469 (%m4_builtin_alternate_name): New.
10470 (&parse_args): Complete the trace requests with alternate names.
10471 (&handle_traces): Hence no longer do it here.
10472 (&trace_requests): Remove, unused.
10474 2001-08-03 Akim Demaille <akim@epita.fr>
10476 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
10477 m4_if, and m4_wrap.

10481 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
10482 (m4_divert_pop): Dump the whole diversion stack when a diversion
10483 mismatch happens.
10484 * bin/autom4te.in (&handle_output): Remember of the first
10485 occurrence of a possibly undefined macro, not the last.
10486 Complain about the possibly undefined macros in the same order as
10487 the appear in the output.
10488 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
10489 * tests/tools.at (autoconf: forbidden tokens, basic)
10490 (autoconf: forbidden tokens, exceptions): No longer sort
10491 autoconf's stderr, as it is now deterministic.
10492 Check that `dnl' is caught.
10494 2001-08-01 Akim Demaille <akim@epita.fr>
10496 * configure.ac: Bump to 2.52c.
10498 2001-08-01 Akim Demaille <akim@epita.fr>
10500 Version 2.52b.

10508 2001-08-01 Akim Demaille <akim@epita.fr>

10511 `die'.
10512 (&END): New.

10514 `END', as `Autom4te::General::END' will be triggered.
10515 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
10516 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

10732 used. Well, then use the prototypes when you can, and runtime as
10733 a last resort.

10951 cross-language link tests can be performed successfully.
10952 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
10953 after $LIBS, for consistency; this should be the general rule since
