1 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
3 * doc/autoconf.texi: Be more consistent about using @acronym with
4 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
5 quite right (it talked about "OSF/Tru64", even though the
6 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
7 and it even mentioned "OSF 4"!) and at this point there's little
8 reason to talk about OSF any more, since it died in 1994.
9 (Specific Compiler Characteristics): Simplify example of
10 negative-size array.
11 (File Descriptors): Reorder to make the text flow better.
12 Remove joke about "appreciate the various levels"; I didn't get it.
13 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
14 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
15 (File Descriptors, Limitations of Usual Tools):
16 Tone down the advice against renaming or removing open files.
17 (Limitations of Usual Tools): Add a new section, on 'rm'.
19 2006-06-26 Stepan Kasal <kasal@ucw.cz>
21 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
22 -lXt in LIBS, idea from Karsten Hopp; this was due since
23 this change:
25 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
26 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
27 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
28 (which belong to Xt, not X itself). See Debian bug 327655.
30 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
32 * configure.ac (AC_INIT): Bump to 2.60a.
33 * NEWS: Update.
35 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
37 Version 2.60.
39 * configure.ac, NEWS: Update.
41 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
43 * config/texinfo.tex: Sync from upstream.
45 * bin/autom4te.in (handle_traces): Transform the `@S|@'
46 quadrigraph correctly in traces.
48 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
49 Fix typos.
51 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
52 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
53 not defined.
54 * doc/autoconf.texi (Changed Directory Variables): New node,
55 to document the whole `datarootdir' business a bit better.
56 * NEWS: Update.
57 * tests/torture.at (datarootdir workaround): Extend test.
58 Prompted by report by Alexandre Julliard.
60 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
62 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
63 when using default mode of IBM C 6 for AIX. Problem and two-line
64 fix reported by Larry Jones.
66 2006-06-22 Alexandre Julliard <julliard@winehq.org>
68 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
69 about literal '${datarootdir}' if a definition is found in the
70 output file.
72 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
74 * NEWS: Use "M4" rather than "m4" when appropriate.
75 Problem reported by Eric Blake.
76 * doc/autoconf.texi: Likewise.
77 Use @acronym around BSD, GCC, and GNU when appropriate.
78 (Why GNU M4): Renamed from "Why GNU m4".
79 (Redefined M4 Macros): Mention that Posix
80 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
81 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
82 to int.
84 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
86 * bin/autom4te.in (handle_output): Do not forbid the empty
87 pattern.
88 * tests/tools.at (autoconf: the empty token): New test.
90 2006-06-20 Stepan Kasal <kasal@ucw.cz>
92 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
93 calls, so that we do not care whether they are LIFO or FIFO;
94 in the m4_wrap, do not check which diversion is the topmost
95 one, just check that the stack is balanced at the end.
96 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
97 base diversion forever--pop the previous diversion before
98 opening the new one; consequently, remove the m4_wrap call.
99 * lib/autotest/general.m4 (AT_INIT): Likewise.
100 * tests/m4sugar.at: Do not use
101 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
103 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
104 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
106 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
107 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
108 Rework example of m4wrap token-pasting trouble so that it doesn't
109 care whether it's LIFO or FIFO.
110 Fix some "contrary to"s that are awkward in English.
112 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
114 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
115 to `yes' instead of `int$1_t' if the type is found, for more
116 consistent configure output (where $1 is the number of bits).
117 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
118 Suggested by Bruno Haible.
120 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
121 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
122 with system headers. Report by Bruno Haible.
124 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
126 * config/config.guess, config/config.sub: Sync from upstream.
128 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
129 in order to avoid picking up an older installed frozen m4sh.m4f.
130 Besides an outdated shell startup, this could have been created
131 by an earlier M4 version with incompatible frozen file format.
133 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
135 * README: Recommend m4 1.4.4 instead of 1.4.3..
136 * doc/autoconf.texi: Likewise.
137 (Special Chars in Names): Say that $(.FOO) is portable, as
138 suggested by Stepan Kasal.
139 (Installation Directory Variables, Build Directories):
140 (Automatic Remaking, Subdirectories, Fortran Compiler):
141 (Making testsuite Scripts, Defining Directories):
142 Quote variable usages better.
143 (Making testsuite Scripts): Add clean-local rule to makefile
144 snippet, by Eric Blake.
145 (Installation Directory Variables): Fix table item font.
146 Reword slightly to clarify. Generalize advice about
147 not using special characters to include all file-related
148 vars, not just VPATH.
149 (Special Chars in Variables): Warn about special characters in
150 $(srcdir) too.
151 (Assignments): Clarify default-value example as suggested by
152 Ralf Wildenhues in
153 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
154 (Special Shell Variables): Note leading ./ or ../, as suggested
155 by Eric Blake.
156 (Limitations of Builtins): Under cd, warn about CDPATH.
157 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
158 Ralf Wildenhues.
160 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
162 * doc/autoconf.texi (Configuration Actions): Remove duplicate
163 `@var', for texi2html.
164 (Systemology): Some more word wrapping, for DVI output.
165 (autom4te Invocation): The short option for `--melt' is `-M',
166 not `-m'.
168 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
170 * doc/autoconf.texi: More formatting and English tweaks,
171 many suggested by Ralf Wildenhues.
172 Reword to avoid "@code{...}'s" and the like, since it's ugly
173 with Emacs info mode. discontents -> woes.
174 Put a few "will"s back. time stamp -> timestamp.
175 side-effect -> side effect.
177 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
179 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
180 Warn about $@ not persisting. Problem reported by Julien Danjou in
181 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
182 (Special Chars in Names): Renamed from Leading _ in Macro Names.
183 Mention other special chars, too.
185 2006-06-14 Eric Blake <ebb9@byu.net>
187 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
189 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
191 * doc/autoconf.texi: Some systematic minor improvements, as
192 follows. Use "makefile" when talking about makefiles
193 generally (which might be named "makefile" or "Makefile" or even
194 "foo.mk"), "Makefile" when talking about a specific makefile
195 called "Makefile". This unclutters the text from weird quotes
196 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
197 values" rather than "@var{foo}s" and similar constructs containing
198 "}s". Use "Make rules" rather than "Makefile rules". Minor
199 English-language improvements. Change the prefix "sub-" to "sub"
200 and "re-" to "re".
201 Put blank lines around examples more consistently.
202 Avoid "rather" and "very" as intensifiers.
203 Avoid "will" as an auxiliary.
204 (Limitations of Make): Split this node into....
205 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
206 (Leading _ in Macro Names, Backslash-Newline-Newline):
207 (Backslash-Newline Comments, Long Lines in Makefiles):
208 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
209 (obj/ and Make, make -k Status, VPATH and Make):
210 (VPATH and Double-colon, $< in Explicit Rules):
211 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
212 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
213 New nodes, resulting from splitup of Limitations of Make.
214 All cross-references changed. Raise the top node from
215 a section to a chapter, and all subnodes accordingly.
216 Redo the introductory wording to match the new organization.
217 (Installation Directory Variables): Use an example that is
218 closer to what Autoconf actually does. Mention that VPATH's
219 value should not contain metacharacters or white space.
220 (Fortran Compiler): Fix a VPATH bug in an example.
221 (Leading _ in Macro Names): Mention that this problem is no longer
222 of practical concern.
223 (VPATH and Make): Reword the advice to make it clearer
224 that Autoconf and Automake support VPATH in non-GNU make, but
225 many packages have bugs in this area.
226 ($< in Explicit Rules): Refer to Build Directories rather
227 than using a (non-VPATH-safe) example.
228 (Automatic Rule Rewriting): Mention the sort of disaster that
229 can ensue with Solaris-style rule rewriting with VPATH.
231 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
233 * doc/install.texi (Compilers and Options): Weaken the
234 suggestion to use GNU make for VPATH builds.
236 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
237 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
239 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
240 in regular expression.
242 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
244 * doc/autoconf.texi (Installation Directory Variables):
245 Drop extra @samp from `@table @samp' item.
246 (Limitations of Usual Tools): Comment fix.
247 Do not nest @samp just to point to other table items.
248 (Writing testsuite.at) <AT_CHECK>: The second argument to
249 `@dvar' is already @samp'ed.
250 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
251 do not use @var in the second argument.
253 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
255 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
256 $as_shell.exe too. Problem reported by Andreas Buening in
257 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
259 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
261 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
262 `unused variable' compiler warning, for `-Wall -Werror'.
263 Reported by Jaap Haitsma in
264 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
266 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
268 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
269 case the compiler dumps core. Problem reported for
270 OpenServer 5.0.7 by Tim Rice in
271 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
272 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
273 Likewise.
275 2006-06-06 Tim Rice <tim@multitalents.net>.
277 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
278 "ERROR" only shows up in "make check" output if there is an
279 error.
281 2006-06-06 Eric Blake <ebb9@byu.net>
283 * tests/tools.at (automatically allowed tokens): Fix typo.
285 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
287 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
289 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
290 typically overflows on x86 CPUs, even though the C standard
291 requires otherwise.
293 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
295 * configure.ac (AC_INIT): Bump to 2.59e.
296 * NEWS: Update.
298 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
300 Version 2.59d.
302 * config/texinfo.tex: Sync from upstream.
304 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
305 seen, invoke libtoolize with `--ltdl' argument.
306 * lib/autom4te.in (Autoreconf-preselections): Adjust.
307 * NEWS: Update.
308 Suggested by Eric Blake.
310 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
312 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
313 reported by Ralf Wildenhues.
314 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
316 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
318 * THANKS: Update.
320 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

330 * tests/local.at (AT_CHECK_M4): New macro, almost identical
331 to...
332 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
333 AT_CHECK_M4.
334 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
335 `expout' as the last parameter.
336 * tests/tools.at: Adapt to the above change.
338 2006-06-04 Stepan Kasal <kasal@ucw.cz>
340 * doc/autoconf.texi (Limitations of Usual Tools): Correct
341 information about race-free implementations of mkdir.
343 2006-06-04 Eric Blake <ebb9@byu.net>
345 * bin/autoreconf.in (help): Document M4 environment variable.
346 * bin/autoconf.as (Usage): Likewise.
347 * bin/autom4te.in (help): Likewise.
348 * doc/autoconf.texi (autom4te Invocation): Likewise.
350 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
352 * NEWS: GNU make now recommended for VPATH builds.
353 Mention that some macros are now documented to be obsolescent.
354 * doc/autoconf.texi:
355 Prefer "current" to "modern" to describe
356 currently-used (albeit perhaps old-fashioned) hosts.
357 Mention which ancient features no longer need to be worried about.
358 setgid -> set-group-ID
359 setuid -> set-user-ID (these are the Posix terms)
360 Fix some misuses of "only".
361 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
362 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
363 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
364 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
365 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
366 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):

370 Mention that these macros are obsolescent.
371 (Installation Directory Variables): shall -> should
372 (File Descriptors): Mention that 0, 1, 2 might get reopened.
373 Mention that it's now safe to use 3 and 4.
374 (Limitations of Usual Tools): cp -r is now specified by Posix.
375 Omit longwinded and obsolescent discussion of cp -f.
376 Modernize discussion of expr, ls.
377 (Limitations of Make): Modernize discussion of VPATH builds.
378 Mention $? as a workaround in some cases.
379 * doc/install.texi (Basic Installation):
380 Mention "./configure; make; make install" first. Be more
381 specific about why this file is generic. Remove unnecessary
382 parens. Remove misleading "only". Remove obsolete advice
383 about csh. Don't say "configure" takes awhile; say it
384 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
385 and CC=c99 rather than CC=c89, as these are blessed by current
386 Posix. Recommend GNU make if doing a VPATH build.
388 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
390 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
391 examples involving shell prompts.
393 2006-06-02 Stepan Kasal <kasal@ucw.cz>
394 and Paul Eggert <eggert@cs.ucla.edu>
396 * doc/autoconf.texi (Here-Documents): Add details about the
397 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
398 use "here-documents" instead of "here documents".

402 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
404 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
406 * doc/autoconf.texi (File System Conventions): Warn about ":"
407 anywhere in directory names.
409 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
411 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
412 about quoting the case statement, just in case.
413 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
414 was fixed in ksh93g; reported by Ralf Wildenhues.

428 argument with leading hyphen. Problem reported by Paul Eggert.
430 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
432 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
433 about quoting ac_try: quote all of it, if any of it seems suspicious.
434 This means we don't have to worry about ${ or sed any more.
435 Also, double-quote the case statement, to work around misuses via
436 underquoting as reported by Ralf Wildenhues in
437 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
438 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
439 undocumented and dangerous macro.
440 Problem reported by Ralf Wildenhues in
441 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
443 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
445 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
446 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
447 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
449 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
451 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
452 since evidently some packages rely on the old, broken behavior.
453 Problem reported by Ralf Wildenhues in
454 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
455 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
456 pre-2006-05-26 definitions, but leave in the comments that
457 these macros are dangerous and should not be used.
458 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
459 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
460 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
461 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
462 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
464 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
466 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
467 the use of 'tr', since this is our only use of 'tr'.
469 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
470 and Paul Eggert <eggert@cs.ucla.edu>
472 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
473 Don't assume 'grep' works on long lines, since AIX grep doesn't.
475 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
477 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
478 the output file in the `${datarootdir}' test.
480 2005-05-28 Stepan Kasal <kasal@ucw.cz>
481 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
483 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
484 mention of `datarootdir' in the input file(s), but literal
485 `${datarootdir}' in the output file, and we haven't warned yet,
486 then warn as well: the user may have (erroneously) used
487 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
488 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
489 * tests/torture.at (datarootdir workaround): Extend this test.
490 * NEWS: Update.
492 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
493 and Paul Eggert <eggert@cs.ucla.edu>
495 * doc/autoconf.texi (autoheader Invocation): The first argument to
496 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
497 alternatives and clear up the language a bit.
499 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
501 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
502 ac_config_guess, ac_config_sub, ac_configure.
503 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
504 Fix typo that prevented an unnecessary space from being removed.
505 Problems reported by Ralf Wildenhues in:
506 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
508 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
510 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
511 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
512 Don't use the term "thread-safe" to talk about mkdir race
513 conditions, since the problem is more a process than a thread
514 issue. Problem reported by Stepan Kasal in:
515 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
516 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
517 the test for 'install' more closely. Look at MKDIR_P first.
518 Look in the PATH, and at /opt/sfw/bin.
519 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
520 Don't bother to try mkdir -p, since we already check mkdir --version;
521 just look at the version number. (There's no easy way to check
522 for race-free implementations.)
523 * tests/tools.at (autoconf: subdirectories): Adjust to above
524 changes, since MKDIR_P now might end in "/mkdir -p".
526 * doc/autoconf.texi (autoheader Invocation): Mention that the
527 first arg of AC_DEFINE_UNQUOTED must be a literal.
528 Problem reported by Ben Pfaff in
529 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
531 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
532 * doc/autoconf.texi (Special Chars in Variables): New section.
533 (Preset Output Variables): Warn about special chars in CPPFLAGS.
534 (Installation Directory Variables): Quote $(datadir) better.
535 (Limitations of Builtins): Describe some of eval's trickiness.
537 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
538 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
539 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
540 in front of every arg, not just trailing args. Quote apostrophes.
541 (_AC_EVAL_ECHO): New macro.
542 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
543 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
544 removed.
545 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
546 exposed by quoting of eval argument. Put the command on line line
547 so it logs better.
548 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
549 (_AC_PATH_X, AC_PATH_X): Quote more safely.
550 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
551 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
552 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
553 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
554 Use eval more safely.
555 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
556 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
557 to be replaced.
558 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
559 lines, exposed by quoting of eval argument.
561 2006-05-26 Stepan Kasal <kasal@ucw.cz>
562 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
564 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
565 initialization of `ac_cv_exeext', do not override it if it was
566 already set, unless it was set to `no', for compatibility with
567 Autoconf-2.13, and comment this.
568 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
569 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
570 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
571 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
572 Document that this test may be overridden by setting
573 `ac_cv_exeext'.
575 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
577 Revert these two patches:
579 2006-04-06 Eric Blake <ebb9@byu.net>
580 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
581 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
582 2006-04-01.
584 2006-04-01 Stepan Kasal <kasal@ucw.cz>
585 Clean up _AC_COMPILER_EXEEXT* macros.
586 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
587 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
588 ac_file to the name of the default output file and call
589 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
590 initial `rm' of the candidate files...
591 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
592 the same list in subsequent `rm' calls, and for the temporary
593 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
594 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
595 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
596 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
597 no longer needed) by libtool. Make it a cache check.
598 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
599 copied here by mistake.
600 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
601 _AC_COMPILER_EXEEXT.
602 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
603 _AC_COMPILER_OBJEXT directly.
604 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
606 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
608 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
609 Fix description of how the buggy `sed' works.
611 2006-05-25 Noah Misch <noah@cs.caltech.edu>
613 Sync from Automake:
615 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
616 ENOLCK. Only mention `make -j' when applicable. Only raise
617 fatal errors when `make -j' is involved. Improve error message.
619 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
621 * doc/autoconf.texi (Here-Documents): We now know more about
622 the variable expansion in here documents bug.
623 Thanks to Tim Rice and Stepan Kasal.
625 * doc/autoconf.texi (Making testsuite Scripts): Add an example
626 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
628 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
630 * tests/autotest.at (Multiline command from M4 expansion):
631 No failure to be expected if the shell quotes newlines in
632 commands in the `set -x' output. Report by Tim Rice.
633 * THANKS: Update.
635 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
637 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
638 expansion in the here-documents used by config.status, as that
639 runs afoul of the Korn shell version M-12/28/93d bug described in
640 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
641 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
642 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
644 2006-05-23 Jim Meyering <jim@meyering.net>
646 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
647 Fix typo introduced with 2006-04-02 change. It reversed the sense
648 of the test.
650 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
652 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
653 ac_dB slightly, to save bytes in the script.
654 Max out at 50 lines, rather than 96; this is more likely
655 (though not guaranteed) to avoid obscure 'sed' failures.
657 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
659 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
660 `tr -d -' as bad option argument. Work around this by deleting
661 an unrelated character.
662 Report by Tim Rice <tim@multitalents.net>.
664 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
665 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
666 Stepan Kasal <kasal@ucw.cz>
668 * doc/autoconf.texi (Particular Programs): Do not promise that
669 we always prefer the GNU version of the program, and that we
670 search according to PATH; both rules can have exceptions.
671 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
672 AC_PROG_SED. Move descriptions of limitations
673 to the Limitations of Usual Tools section.
674 (Limitations of Usual Tools) <sed>: Mention script length
675 limitations with Solaris /usr/ucb/sed.
676 <grep>: Fix wording for empty alternative. Mention that -c and
677 -l should not be combined, and that -E and -F should not be
678 combined.
680 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
681 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
683 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
684 limits in Solaris 8 /usr/ucb/sed by testing a long script.
686 2006-05-22 Stepan Kasal <kasal@ucw.cz>
688 * doc/autoconf.texi (Defining Symbols): Literal parameter of
689 AC_DEFINE is now passed to m4_pattern_allow.
690 * NEWS: Mention that; likewise for AC_SUBST.
691 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
692 the parameter to m4_pattern_allow.
693 * tests/tools.at: Add a check for that.
695 2006-05-22 Stepan Kasal <kasal@ucw.cz>
697 * lib/autoconf/status.m4: Fix typos.
699 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
701 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
702 only the files that this macro generates.
704 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
706 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
707 the HP-UX sed limitation of 99 commands, labels do not count.
708 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
709 in the comment.
710 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
712 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
714 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
715 Import the following fix from coreutils:
717 2006-01-13 Jim Meyering <jim@meyering.net>
719 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
720 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
721 not double-quote uses of that variable, to accommodate the rare
722 case in which getmntent is available in none of the libraries
723 checked. This happens at least on FreeBSD 5.0.
725 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
727 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
728 ac_config_guess, ac_config_sub, and ac_configure, since evidently
729 some other programs unwisely rely on these undocumented vars.
730 But put in warning comments about them.
731 Problem reported by Ralf Wildenhues in
732 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
733 * NEWS: Document that these variables are intended to go away.
735 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
737 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
738 and set the language to C++ (analogous to the equivalent Fortran
739 tests).
741 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
742 * doc/autoconf.texi (C++ Compiler): Document it.
743 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
744 * NEWS: Update.
746 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
748 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
749 that caused config.status to generate 100-command sed scripts; the
750 portable limit is 99.
752 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
754 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
755 variable `ac_d' instead of `d' to avoid infringing namespace.
756 Report by Ralf Menzel.
758 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
760 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
761 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
762 * tests/tools.at (autoconf: subdirectories): New test, taken from
763 the corresponding problem report by Ralf Wildenhues in:
764 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
766 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
767 Quote some uses of shell variables if they might suffer unexpected
768 globbing. This doesn't fix all instances of quoting problems that
769 I found, just the easy ones that look safe.
770 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
771 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
772 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
773 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
774 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
775 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
776 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
777 Likewise.
778 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
779 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
781 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
783 * bin/autoreconf.in ($help): Reword according to the manual.
784 Suggested by Olly Betts.
786 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
787 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
789 * bin/autoreconf.in: Pass the directory argument to
790 `require_configure_ac'. Fix comment.
791 * tests/torture.at (Configuring subdirectories): Expose this.
792 Reported by Olly Betts.
794 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
796 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
797 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
798 Automake as follows:
800 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
801 `$configure_in' instead of `configure.in', to preserve
802 directory component.
804 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
806 * config/config.guess, config/config.sub, config/texinfo.tex,
807 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
809 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
811 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
812 test for C99 conformance; (bool) 0.5 is an integer constant
813 expression, but (bool) -0.5 is not. Problem reported by Fedor
814 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
816 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
818 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
819 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
820 Warn about obsolete install-sh files. Remove stray sentence
821 fragment and fix cross reference.
822 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
823 install -d; this undoes the 2006-05-10 change.
824 (MKDIR_P): Mark with AN_MAKEVAR.
825 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
826 that we don't require $INSTALL to be thread-safe. Move comments
827 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
828 of AC_PROG_INSTALL. Output a message saying that we're checking
829 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
830 MKDIR_P instead of AC_SUBST.
831 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
832 Special magic for MKDIR_P, too.
833 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
834 a dnl.
835 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
837 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
839 Sync from Automake, as follows:
841 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
842 * config/install-sh: Initialize IFS, so field splitting isn't
843 turned off later.
844 * config/mkinstalldirs: Likewise.
845 * config/missing: Remove superfluous quotes. Replace all uses of
846 `[' by `test', for consistency, and for..
847 * config/missing (sed_minuso, sed_output): New variables.
848 (autom4te, help2man, makeinfo): Use them. Unifies detection of
849 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
850 Fixes `missing' to detect `--output' for help2man. Fixes
851 PR automake/483. Report by Dennis J. Linse.
852 (autom4te): Document in `missing --help'.
854 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
856 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
857 * config/install-sh: Don't use 'path' to talk about file names,
858 as per GNU coding standards. Close a race condition reported by Ralf
859 Wildenhues and Stepan Kasal. There is still a race condition
860 on hosts that predate Posix 1003.1-1992, but we can't help this.
861 Don't mishandle weird characters like space on pre-Posix hosts.
862 Invoke mkdir at most once per dir arg on pre-Posix hosts.
863 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
864 AC_PROG_MKDIR_P from AS_MKDIR_P.
865 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
866 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
867 earlier editions are not (including Automake 1.8.3).
868 Do not suggest mkinstalldirs for thread-safety.
869 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
870 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
871 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
872 presence of special characters and race conditions.
873 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
874 in Autoconf's name space.
876 2006-05-10 Bruno Haible <bruno@clisp.org>
877 and Paul Eggert <eggert@cs.ucla.edu>
879 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
880 from Automake with minor changes.
881 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
883 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
885 * config/install-sh: Update to Automake CVS version, as follows:
886 2006-04-25 Stepan Kasal <kasal@ucw.cz>
887 * lib/install-sh: Simplify the expr implementation of dirname.
888 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
889 * lib/install-sh: Handle --, and diagnose unknown options.
891 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
893 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
894 `./autom4te' to create `./testsuite', since the `all' target
895 will ensure its presence, but `installcheck' should not create
896 the uninstalled wrappers.
898 * tests/torture.at (Unusual Automake input files): Skip if we
899 detect automake < 1.8.
901 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
903 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
904 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
905 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
906 * NEWS: Update.
908 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
910 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
911 munge (multiple) white space and other oddities.
912 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
913 single quotes in variable assignment.
914 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
915 and similar failures by adding multiple spaces, tabs, and other
916 special characters.
917 Report and different test suggested by Francesco Romani
918 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
920 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
921 single quotes, we only need to search for single quotes; this
922 both simplifies the search pattern, and makes us less
923 susceptible to `echo' variations for arguments not containing
924 single quotes.
925 (_AC_ARG_VAR_VALIDATE): Likewise.
927 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

948 overflow.
950 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
952 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
953 traditional shells like the Solaris one that do not use the
954 first IFS character for assembling `$*'.
955 Prompted by a related report from autoconf_bug@nro.ca.
957 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
958 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1007 (Portable Shell): Mention the Posix shell.
1009 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1011 * bin/autoconf.as (me): Replace by as_me.
1013 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1015 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
1016 since as_me isn't set yet.
1018 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1020 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
1021 a few minor bugs in this area.
1023 * doc/autoconf.texi (Programming in M4sh): Comment out the
1024 documentation of AS_BASENAME, for now.
1025 (Shell Substitutions): Do not use AS_DIRNAME in an example.
1026 (Limitations of Builtins) <basename>: Do not refer to
1027 AS_BASENAME.
1028 * bin/autoconf.as (me): Don't use AS_BASENAME.
1029 (dir): Remove the unused variable.
1030 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from

1036 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
1037 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
1038 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".

1044 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1046 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
1047 of "run time" and "run-time" changed to "runtime", for consistency.

1049 * lib/autoconf/functions.m4: Likewise.
1050 * lib/autoconf/general.m4: Likewise.
1051 * lib/autoconf/headers.m4: Likewise.
1053 * doc/autoconf.texi (Run Time): Document the exit status situation
1054 with more accuracy and detail.
1056 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1058 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
1059 Archive is not officially `GNU' any more. Update URL.
1060 (Defining Directories): Likewise
1061 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
1063 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1065 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1066 newline from the `trap' code to finish `config.log'; the NetBSD
1067 /bin/sh resets the exit status after an empty command, as
1068 documented in doc/autoconf.texi.
1069 Reported by Dalibor Topic <robilad@kaffe.org>.
1071 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1073 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1074 Suggested by Bruno Haible.
1076 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1078 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1079 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1080 Instead, just list the shells that we know work.
1081 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1082 changed. Be more cautious about the _cv_ variable.
1083 * tests/tools.at (Syntax of the shell scripts): Check the
1084 _cv_ variable once, at first, to avoid an internal autoconf error
1085 when sh -n does not work.
1087 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1089 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1091 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1093 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1094 use ">&-" since we're only 99.999% sure that this is portable,
1095 and since the MinGW bug is fixed in a different way.
1096 * lib/autotest/general.m4 (AT_INIT): Likewise.
1098 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1100 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1101 before opening config.log, to avoid hitting a bug on MinGW.
1103 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1105 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1106 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1107 This works around a MinGW bug reported by Eric Paire.
1108 Make sure that all writes to the log file append to it,
1109 rather than possibly losing data.
1110 * lib/autotest/general.m4 (AT_INIT): Likewise.
1112 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1114 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1115 description.
1117 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1119 * NEWS: Update.
1121 * configure.ac (AC_INIT): Bump to 2.59d.
1123 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1125 Version 2.59c.
1127 * Makefile.maint (news-date-check): Do not require a leading `*'
1128 before the release date in NEWS.
1130 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1131 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1133 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1134 the instantiated file do not contain the string 'datarootdir'
1135 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1136 @mandir@, replace the reference '${datarootdir}' by the value.
1137 * tests/torture.at (datarootdir workaround): New test.
1138 * NEWS: Advertise this temporary fixup.
1139 Based on a patch by Bruno Haible, reported and analyzed by
1140 Paul Eggert and Noah Misch.
1142 2006-04-12 Eric Blake <ebb9@byu.net>
1144 * tests/autotest.at (Debugging a failed test): Fix comment.
1146 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1148 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1149 all the changes since 2006-04-07.
1151 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1153 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1154 succeeded, but `ln -s file dir' failed, take care to remove the
1155 leftover target before the next test, to prevent its spurious
1156 failure; also make sure `ln file dir' works before selecting it.
1157 Thanks to Keith Marshall for pointing this out.
1158 * THANKS: Update.
1160 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1161 assignments in `at_debug_args', so that we put them correctly
1162 in the `run' script.
1163 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1164 Reported by Eric Blake.
1166 2006-04-11 Eric Blake <ebb9@byu.net>
1168 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1169 top-level tests after micro-suite has been run. Used in...
1170 (Debugging a successful test, Debugging script and environment),
1171 (Debugging a failed test): ...these new tests. The first of these
1172 is fixed by...
1173 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1174 macro, split out from...
1175 (AT_INIT): ...here, so that using -d also generates a run script.
1176 Document that -d inhibits top-level logging.
1177 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1178 inhibits top-level logging; debug scripts are created.
1180 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1181 check.
1182 * tests/autotest.at (Empty test, Empty check): New test to check it.
1184 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1185 from gcc.
1187 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1189 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1190 the files if a problem appears. Make the empty *.at files
1191 read-only, too. Proposed by Ralf Wildenhues.
1193 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1195 * config/Makefile.am: Add comment to force updated Makefile.in.
1197 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1198 space only patch to this file, this patch causes the Makefile.in
1199 files that include freeze.mk to be updated, and thus have a
1200 newer time stamp again, which in turn makes a pristine CVS
1201 checkout have correct time stamps.
1203 * Makefile.maint (cvs-sv): New macro, to be used..
1204 (config.guess-url_prefix, config.sub-url_prefix)
1205 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1206 point to CVS text checkout of Gnulib files.
1207 (copyright-check): Bump current year.
1208 (announcement): Do not hard-wire `./announce-gen'.
1209 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1210 correctly.
1211 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1212 `chmod +x'.
1213 (wget_files): Update config.guess, config.sub, texinfo.tex by
1214 `wget-update', now that their URLs work again.
1216 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1218 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1219 Problem noted by Paul D. Smith.
1221 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1223 * doc/autoconf.texi: Remove unused words from word list.
1224 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1225 .x-sc_trailing_space: New files.
1227 * doc/standards.texi: Sync from gnulib.
1229 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1230 `LIBOBJDIR' as experimental.
1232 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1233 with a target directory; it's internally implemented as `cp'
1234 anyway, but since Autoconf advertises the possibility to use
1235 a target directory when LN_S is `ln -s', we need to find out.
1236 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1237 analyzed by Keith Marshall <keith.marshall@total.com>.
1239 * THANKS: Update.
1241 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1243 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1244 confdefs.h as-is. In general, if it has backslash-newline or the
1245 like, then it doesn't work either to sort or to remove empty
1246 lines.
1248 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1250 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
1252 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
1254 * lib/autom4te.in (Automake-preselections): Preselect
1255 _AM_SUBST_NOTMAKE.
1257 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1259 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1260 apostrophe within a single-quoted string, as this is the usual
1261 tradition and is easier to read than '"'"'. Don't rely on the
1262 shell treating "$/" like '$/'. Use a more-consistent indenting
1263 style for the trap.
1265 2006-04-09 Eric Blake <ebb9@byu.net>
1267 * tests/autotest.at (Backquote command substitution),
1268 (Multiline backquote command substitution): Remove mistaken
1269 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1270 applied...
1271 (Parenthetical command substitution, Multiline parenthetical
1272 command substitution): here.
1274 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1276 Import macros from gnulib (often changing their name).
1278 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

1290 (Pointers): Add Gnulib URL.
1291 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
1292 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
1293 Gnulib section.
1294 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
1295 suggest a #define rather than a typedef for _Bool, and mention
1296 Gnulib rather than trying to substitute stdbool code.
1297 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
1298 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
1299 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
1300 AC_STRUCT_DIRENT_D_TYPE.
1301 (Particular Types): Mention stdint.h and inttypes.h as standard
1302 headers too.
1303 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
1304 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
1305 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
1306 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
1307 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
1308 (C Compiler): Move AC_C_LONG_DOUBLE to ...
1309 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
1310 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
1311 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
1312 (Coding Style). Don't mention m4_expand_once.
1313 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
1314 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
1315 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
1316 (AC_CHECK_FUNCS): Use it.
1317 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.

1320 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
1321 (AC_HEADER_ASSERT): New macro.
1322 (AC_HEADER_STDBOOL): Don't assume "#error" works.
1323 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
1324 Catch a bug in an HP-UX C compiler.
1325 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
1326 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
1327 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):

1329 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
1330 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
1331 New macros.
1333 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
1334 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
1336 2006-04-08 Stepan Kasal <kasal@ucw.cz>
1338 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
1339 of the warning introduced by the 2001-08-28 change.
1341 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
1342 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1344 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
1345 variables shall be overriden by the cache.
1346 * tests/torture.at (AC_ARG_VAR): Test also with a first value
1347 that contains braces.
1349 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1351 Revert the patch from 2006-04-01 and only improve
1352 _AS_DETECT_BETTER_SHELL:
1354 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1355 skip nonexistent directories.
1356 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1357 only shell candidates which exist.
1358 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1359 * lib/autotest/general.m4 (AT_INIT): No need to give three
1360 parameters to _AS_PATH_WALK.
1362 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
1363 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1365 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1366 distinguish m4sugar macros.
1367 * tests/tools.at (autoupdating with aclocal and m4_include):
1368 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1369 test case by Noah Misch <noah@cs.caltech.edu>.
1371 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1373 Revert my change from 2006-03-17, in other words:
1374 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1375 and DUALCASE=1.
1376 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
1377 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
1378 it is set.
1380 2006-04-07 Eric Blake <ebb9@byu.net>
1382 * doc/autoconf.texi (Programming in M4sh): Document that
1383 AS_MKDIR_P exits the script on failure.
1384 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1386 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1388 * config/elisp-comp, config/install-sh, config/mdate-sh,
1389 config/missing, config/mkinstalldirs: Sync from Automake.
1391 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
1392 from Automake.
1394 * doc/make-stds.texi: Sync from gnulib.
1396 2006-04-06 Eric Blake <ebb9@byu.net>
1398 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1399 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1400 2006-04-01.
1402 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
1403 Eric Blake <ebb9@byu.net>,
1404 Paul Eggert <eggert@cs.ucla.edu>,
1405 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1407 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1408 whether `set' quotes correctly: redirect stderr of the tested
1409 `set', and use a subshell, for Ultrix; use `sed' instead of
1410 `grep' for zsh `set' which may write binary output; match only
1411 at the beginning of a line, to avoid false positives.
1412 In order to avoid false positives by unrelated variables with
1413 multiline content, put the dump algorithm in a subshell and
1414 unset all variables containing newlines (except some which are
1415 special to the shell). Warn about cache variables that are
1416 unset.
1418 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1420 * config/config.guess, config/config.sub, config/texinfo.tex:
1421 Sync from upstream.
1423 * tests/mktests.sh: Reword comments.
1425 * tests/mktests.sh: Only skip internal macros starting with
1426 `_AC_' or `__AC_'. Noted by Stepan Kasal.
1427 Update exclusion lists for the test suite to this end:
1428 (AC_ARG_VAR): Do test this now.
1429 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
1430 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
1431 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
1432 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
1434 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
1435 shell issue with double-quoted command substitutions of native
1436 commands.
1437 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
1438 Marshall.
1440 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
1441 no file matches the glob, discard the warning, set `nullglob'.
1442 (syntax-check): Likewise.
1443 (sc_cast_of_x_alloc_return_value): Likewise.
1444 (sc_cast_of_alloca_return_value, sc_error_exit_success)

1453 <tab><space> where this makes sense.
1455 2006-04-06 Stepan Kasal <kasal@ucw.cz>
1457 * tests/Makefile.am (maintainer-check-posix):
1458 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
1460 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
1461 ac_config_<foo>s again, sometimes normalized, sometimes not.
1462 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
1463 (AC_CONFIG_COMMANDS): Do not do so here.
1464 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
1465 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
1466 2005-07-25 rewrite. Noticed by Noah Misch.
1468 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
1469 _AC_PRESERVE_HELP_ORDER, ...
1470 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
1472 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
1473 inside m4_expand_once; it is redundant.
1475 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
1476 for --help from Cygnus `configure.'
1478 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

1485 * lib/autoconf/status.m4: Replace <space>''<tab> with
1486 <tab><space> where this makes sense.
1488 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
1489 Noah Misch <noah@cs.caltech.edu>
1491 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
1492 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
1493 * doc/autoconf.texi (Help Formatting): New node.
1494 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
1496 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1498 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
1499 lib/autoconf/specific.m4, lib/autoconf/status.m4,
1500 lib/autoconf/types.m4, lib/autotest/general.m4,
1501 tests/mktests.sh, tests/torture.at: White space cleanup:
1502 remove some SPACE before TAB, or add quoting ('' or @&t@).
1504 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
1506 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
1508 2006-04-05 Eric Blake <ebb9@byu.net>
1510 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
1511 empty test suite works.
1512 * tests/autotest.at (Empty test suite): Remove xfail.
1514 2006-04-05 Noah Misch <noah@cs.caltech.edu>

1517 TAGS to ac_config_<foo>s.
1518 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
1519 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
1520 normalizing it, consistent it with previous releases.
1521 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
1523 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1525 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
1526 Use simplified args that Eric Blake originally suggested.
1528 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
1530 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
1531 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
1532 Use 'comm' rather than N instances of grep; this also fixes a bug
1533 whereby substrings were incorrectly matched, causing us to not
1534 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
1535 (exclude_list): Exclude empty macros.
1536 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
1538 Use awk rather than grep -E or egrep, to avoid
1539 portability problems with regular expressions containing newlines.

1541 Switch from grep to awk syntax.
1542 (ac_exclude_script): Renamed from ac_exclude_egrep.
1543 (au_exclude_script): Renamed from au_exclude_egrep.
1545 2006-04-04 Noah Misch <noah@cs.caltech.edu>
1547 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
1548 a subdirectory subject to Cygnus `configure'.
1549 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
1551 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
1552 report request when we have no AC_PACKAGE_BUGREPORT.
1554 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1556 * THANKS: Update.

1563 typedef'ed restricted pointer, to catch a compiler bug on
1564 HP-UX 11.x, and fix warnings so it passes with -Werror.
1565 (_AC_PROG_CC_C99): Likewise.
1566 Reported by Albert Chin <china@thewrittenword.com>.

1584 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1586 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
1587 to log, point to testsuite output tree.
1589 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>

1596 Remove; all uses removed.
1597 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

1617 Clean up _AC_COMPILER_EXEEXT* macros.
1619 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1620 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1621 ac_file to the name of the default output file and call
1622 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1623 initial `rm' of the candidate files...
1624 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1625 the same list in subsequent `rm' calls, and for the temporary
1626 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1627 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1628 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1629 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1630 no longer needed) by libtool. Make it a cache check.
1631 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1632 copied here by mistake.
1633 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1634 _AC_COMPILER_EXEEXT.
1635 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1636 _AC_COMPILER_OBJEXT directly.

1667 * lib/autoconf/general.m4 (_AC_INIT_VERSION): Emit script name and
1668 Autoconf version number despite a zero- or one-argument AC_INIT.
1670 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
1671 subordinate tools.
1672 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
1673 * doc/autoconf.texi (autoreconf Invocation): Document it.
1675 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
1676 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.

1680 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Allow use in shell lists.

1682 rm failed to remove it.
1684 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1686 * bin/autoupdate.in: Redefine m4_location so that warnings print
1687 the correct lines of the input file by subtracting..
1688 (_au__first_line): ..this new definition.
1690 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
1691 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
1692 Remove stray newline in output.
1693 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
1694 AC_DEFUN this for autoconf, including the obsoletion diagnose.

1696 m4sugar macros.
1697 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
1698 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

1701 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
1702 hairy details.
1703 The AC_LANG_SAVE issue was reported against Libtool by
1704 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
1705 Kristian Kvilekval <kris@cs.ucsb.edu>.
1707 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1709 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
1710 switch all of them on and of when necessary. Fixes the bug when
1711 m4sugar macros (e.g., m4_define) were expanded after the first
1712 automatic update (e.g., after AC_PREREQ or AC_INIT).
1714 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

1739 aclocal cannot be given on the command line.
1741 2006-03-29 Paul Eggert <eggert@cs.ucla.edu>
1743 * doc/autoconf.texi (Programming in M4sh): Mention AS_BASENAME.

1745 (File System Conventions): Put discussion of // versus / here, and
1746 modernize it a bit.

1748 after dirname, since it got moved to the above sections.
1749 All this was inspired by a patch proposed earlier by Eric Blake.

1759 2006-03-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1761 * bin/autoscan.in: The value of find_configure_ac should be
1762 checked for existence, so we don't barf over a nonexisting
1763 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
1765 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1767 * bin/autoupdate.in: Fix some typos.
1769 2006-03-21 Stepan Kasal <kasal@ucw.cz>
1771 * doc/autoconf.texi (Installation Directory Variables): Fix typo.

2286 2005-12-31 Stepan Kasal <kasal@ucw.cz>
2288 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Use $PATH_SEPARATOR;
2289 ":" caused problems on OS/2-EMX. Suggested by Andrew Belov.
2291 2005-12-29 Paul Eggert <eggert@cs.ucla.edu>
2293 * doc/autoconf.texi (Shell Substitutions): Warn about unbalanced

2322 (Limitations of Builtins): Likewise.
2324 2005-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2326 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Pass
2327 CONFIG_SHELL in the environment of the configure rerun.
2328 * doc/autoconf.texi (Here-Documents, config.status Invocation):
2329 Suggest passing CONFIG_SHELL absolute, and in the environment
2330 rather than as option.
2332 2005-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2334 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):

2346 ac_clean_files and LIBOBJS.
2348 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2350 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
2351 Factor functionality to..
2352 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
2353 `AC_SUBST($1)' in the public version.
2354 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
2355 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
2356 ac_pt_* variables.
2358 2005-11-01 Stepan Kasal <kasal@ucw.cz>
2360 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
2361 filesystems.

2367 2005-10-27 Stepan Kasal <kasal@ucw.cz>
2369 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
2370 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
2372 2005-10-25 Stepan Kasal <kasal@ucw.cz>
2374 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
2375 conftst2.$ac_objext.
2376 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
2378 2005-10-24 Stepan Kasal <kasal@ucw.cz>
2380 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
2381 conftest.o, to see whether the compiler really obeys; rm the object
2382 file before and after the test and register it with ac_clean_files.
2383 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
2385 2005-10-21 Stepan Kasal <kasal@ucw.cz>
2387 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
2388 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
2389 code so that the most common case requires less forks.
2391 2005-10-20 Stepan Kasal <kasal@ucw.cz>
2393 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is

2401 the latter'', in two places.
2403 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
2405 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
2406 AC_LANG_PROGRAM, fixing a typo. Don't give details about
2407 the inner workings of AC_LANG_FUNC_LINK_TRY.
2408 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
2409 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
2410 by the function rather than ignoring it.
2411 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
2412 comparing its address. Intel's interprocedural optimization was
2413 outsmarting the old heuristic. Problem reported by
2414 Mikulas Patocka.
2416 2005-10-19 Stepan Kasal <kasal@ucw.cz>
2418 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
2420 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
2422 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

2425 2005-10-04 Stepan Kasal <kasal@ucw.cz>
2427 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
2428 before removing it (chmod -R u+rwx); there are three instances of this.
2430 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2431 Stepan Kasal <kasal@ucw.cz>
2433 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
2434 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
2435 make its content writable before removing it. Remove an errorneous
2436 comment from the end, where the logs of the failed tests are copied
2437 to the main log file.
2439 2005-09-27 Stepan Kasal <kasal@ucw.cz>
2441 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
2442 in case the computer is too quick. Double quote the configure.ac
2443 snippets.
2445 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
2446 problems if the testsuite were running too fast.
2448 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2450 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2451 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2452 (which belong to Xt, not X itself). See Debian bug 327655.
2453 * NEWS: Mention this.
2455 2005-09-07 Stepan Kasal <kasal@ucw.cz>
2457 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
2459 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
2461 * config/move-if-change: Don't output "$2 is unchanged";
2462 suggested by Ben Elliston. Handle weird characters correctly.
2464 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2466 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2467 calls, so that the final expansion of this macro is shorter.
2468 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2469 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2470 the cleanup there. Use AS_VAR_* macros, to be more general.
2471 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2473 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2475 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
2477 2005-09-01 Stepan Kasal <kasal@ucw.cz>
2479 * doc/autoconf.texi (Configuration Headers): Add an index entry
2480 for AH_HEADER.
2482 2005-08-26 Pavel Roskin <proski@gnu.org>
2484 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
2485 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
2486 running xmkmf.
2488 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
2490 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2491 The previous patch didn't work, so try a better one.
2493 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2495 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
2496 in the example. Reported by Bruno Haible.
2497 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2498 "if $undefined_var;" succeeds with my shell.
2500 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2501 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2502 but change the m4_divert_text to m4_divert_once.
2504 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
2506 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2507 Work around bug in Solaris /usr/xpg4/bin/awk.
2508 The bug is present in at least Solaris 8 through 10.
2510 2005-08-24 Stepan Kasal <kasal@ucw.cz>
2512 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2513 some evil values and relying on the fact that $* concatenates the
2514 parameters by the first character from IFS.
2516 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2517 Stepan Kasal <kasal@ucw.cz>
2519 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
2520 first header appears, define AH_HEADER.
2521 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2522 Update limitations about when to call AC_CONFIG_HEADERS.
2523 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2524 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2525 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2526 ``Configuration Actions''; fix their index entries.
2528 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2529 options correctly. Process N-M as M-N if M is smaller than N.
2530 Process ranges correctly so that N-N will run only N.
2531 Sort and uniquify the tests that will be run. If there is more
2532 than one test, reinsert the banners for the tests.
2533 * tests/autotest.at (Keywords): Unmark XFAIL.
2535 2005-08-23 Stepan Kasal <kasal@ucw.cz>
2537 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
2538 before passing the macro name to AH_TEMPLATE.
2540 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2541 now opens log after option processing; in particular, --version
2542 and --help do not touch config.log.
2544 * Makefile.maint: Revert the change from 2005-08-12.
2546 2005-08-22 Stepan Kasal <kasal@ucw.cz>
2548 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
2549 common code to...

2552 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2554 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
2555 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
2556 Language cleanup.
2558 * doc/autoconf.texi (Defining Symbols, Changed Results):
2559 Prepend to LIBS, not append, in examples.
2561 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2563 When building in place, set srcdir="."; suggested by Tim Van Holder.
2565 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2566 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2567 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2568 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
2569 does not mean "no --srcdir option".
2571 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2573 * tests/autoscan.at (autoscan): New file.
2574 * tests/suite.at: Use it.
2575 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
2576 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
2578 * tests/autotest.at (Keywords): Test keywords combinations.
2580 2005-08-12 Stepan Kasal <kasal@ucw.cz>
2582 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2583 add "2>&1"; gzip 1.2.4 prints help on stderr.
2585 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2587 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2588 was pushdef'ed twice while popped only once. Push it only once.
2589 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
2591 2005-07-26 Stepan Kasal <kasal@ucw.cz>
2593 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
2594 prefixed by mere "===", not "configure: === ".
2596 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
2598 * Makefile.maint: Update from Bison.
2600 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
2601 "<tab>" in comment, so that the point is understandable.
2603 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2605 Rewrite substantial part of lib/autoconf/status.m4.
2606 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2607 and CONFIG_COMMANDS are not processed in four separate loops.
2608 Instead, there is one main loop. This alows that the common code
2609 is expanded only once, thus config.status (and configure) is smaller.
2611 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2612 the AC_LIST_FILES and cousins macros are no longer used.
2614 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2615 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2616 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2617 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2618 contain the initialization, nor the for loop, nor the associated
2619 commands; all these go to ...
2620 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2621 _AC_OUTPUT_CONFIG_STATUS.
2622 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2623 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2624 (_AC_OUTPUT_FILE): The creation of the sed script ...
2625 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2626 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2627 _AC_OUTPUT_MAIN_LOOP.
2628 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2629 _AC_CONFIG_COMMANDS): Use ...
2630 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2631 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2632 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2633 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2634 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2635 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2636 ... new macros.
2637 (_AC_CONFIG_UNIQUE): Update.
2638 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2639 Replaced by this ...
2640 (_AC_LIST_TAGS): ... new common macro.
2641 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2642 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2643 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2644 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2645 this didn't belong to the `config commands' section.
2646 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2647 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2648 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2649 to the `config commands' section either.
2650 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2651 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2653 ... and many changes to the comments nearby.
2655 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
2656 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
2657 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2658 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
2659 (#define header templates): The comment at the top of the generated
2660 header now includes the name(s) of the source file(s).
2662 Several unrelated small changes:
2664 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2665 parameter to AC_DIAGNOSE.
2666 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2667 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2668 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2669 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2670 with AU::AC_OUTPUT.
2671 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2672 in AC_OUTPUT doesn't double-quote it either.
2673 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
2674 parameters.
2676 2005-07-10 Stepan Kasal <kasal@ucw.cz>
2678 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
2679 versions of Portland Group compiler produce single- and double-quoted
2680 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
2681 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
2683 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2685 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2686 This is a corrected version of yesterday's patch.
2688 2005-07-07 Stepan Kasal <kasal@ucw.cz>
2690 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
2691 path, too; insert a "===" to emphasize the line.
2693 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
2694 ac_cv_build_alias to ac_build_alias.
2695 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
2697 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
2698 change eliminates it. Problem reported by Alexandre Duret-Lutz.
2699 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
2700 (AC_ARG_VAR): ... here.
2701 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
2702 target_alias.
2704 Keep a list of all precious variables and process them with one simple
2705 for loop, instead of expanding all commands, or, OTOH, complicated
2706 processing of output of "set".
2707 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
2708 variable names in new macro...
2709 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
2710 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
2711 a loop to assign all ac_env_* and ac_cv_env_* variables.
2712 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
2713 to INIT_PREPARE.
2714 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
2715 its value to shell variable ac_precious_vars and call
2716 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
2717 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
2718 _AC_ARG_VAR_VALIDATE.
2720 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
2721 and the AC_SUBSTs ...
2722 (AC_INIT): ... here.
2724 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
2725 the ac_subst_files section in config.log.
2727 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
2729 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

2739 They are generated by the Tru64 v5.1B shell.
2741 2005-07-05 Stepan Kasal <kasal@ucw.cz>
2743 Fix my changes from 2005-07-01; reported by Noah Misch.
2744 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
2745 description, the macro now accepts only a single tag.

2753 is not set, use at_top_builddir, for compatibility with older
2754 versions of autoconf.
2756 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
2758 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
2759 Problem reported by Patrick Welche.
2761 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
2763 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
2764 sed substitution command, so that we allow | in program prefixes
2765 and program suffixes. (& is a problem anyway; we're not fixing
2766 that here.)
2767 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
2768 configure_input, top_builddir, srcdir, etc.
2769 * lib/autotest/general.m4 (AT_INIT): Likewise, for
2770 PATH_SEPARATOR in AUTOTEST_PATH.
2772 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
2774 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the

2780 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

2798 about #include <config.h>.
2799 (Generic Functions): Mention the Gnulib project.
2800 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
2802 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
2803 document to output the default config_* lists to config.status.
2804 Don't recognize option --file, if the functionality is not there.
2805 Likewise for --header; moreover, recognize --he and --h as shortcuts
2806 for --help in that case.
2808 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
2809 matches the order of execution. No code changed.

2831 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
2832 (AC_SUBST): Call it.
2833 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
2834 the directory specific variables; but don't call it for configure_input.
2836 2005-06-28 Derek Price <derek@ximbiot.com>
2838 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
2839 addition.
2841 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
2843 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
2844 directory have inherent problems with special characters like spaces,
2845 due to limitations in Make syntax. Problem reported by Alexandre
2846 Duret-Lutz.
2847 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
2848 Also, fix Tru64 porting problem with shell patterns,

2860 from Justace Clutter.
2861 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
2862 variable into diagnostic. Make the diagnostic an error, not a warning,
2863 because we really don't support spaces and suchlike in dir names.
2864 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
2865 Don't worry about backslashes in srcdir; it can't happen now.
2866 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
2867 Simplify ac_optarg handling.
2868 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

2878 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
2879 that '\|' is not allowed in BREs; recommend using newline separated
2880 list of patterns instead of multiple -e options.
2882 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
2884 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

2890 2005-06-21 Stepan Kasal <kasal@ucw.cz>
2892 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
2893 b, t, r, w commands require single space, while : cannot have any.
2894 (Special Shell Variables): Fix sed code this in the example.
2895 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
2896 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
2898 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
2899 expand to the empty list. Don't use two pairs of m4_changequote,
2900 it's not necessary.
2902 2005-06-20 Derek Price <derek@ximbiot.com>
2904 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
2906 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
2908 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
2909 * doc/autoconf.texi:
2910 Don't mention Solaris versions so much, if a
2911 problem is common to all extant versions of Solaris. Say "SunOS
2912 4" instead of "SunOS" for SunOS 4.
2913 (awk): Mention more of the limitations of traditional Awk.
2914 (cat): Don't talk about cat -v.
2916 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

2921 to be compatible with glibc strverscmp.
2922 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
2924 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
2925 on Mac OS X 10.4 reported by Peter O'Gorman in:
2926 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
2927 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
2928 Use shell builtins rather than 'expr', to work around expr bug.
2930 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
2932 * doc/autoconf.texi: "filesystem" -> "file system".
2933 "behaviour" -> "behavior".

2935 * lib/autoconf/general.m4: Omit blank after ":" sed command,
2936 as per POSIX.
2937 * lib/m4sugar/m4sh.m4: Likewise.
2938 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
2939 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
2941 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
2942 (.x.1): Ignore the time stamp in the .TH line when deciding whether
2943 to update the man page. That way, we don't have to check in new
2944 man pages every month.
2946 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
2947 quotes and backslashes. Patch from Derek Price.

2952 AS_TR_SH.
2954 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
2956 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
2957 -u, since it outputs chatter if the input files are the same.
2958 Problem reported by Ralf Menzel.
2960 2005-06-08 Derek Price <derek@ximbiot.com>
2962 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
2963 renaming them since they are about to be redefined anyhow.
2965 2005-06-08 Derek Price <derek@ximbiot.com>
2967 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
2968 redefined M4 macros to this node. Document m4_include & m4_sinclude.
2969 Move m4_undefine to alphabetical order.
2971 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
2973 * README: Recommend GNU M4 1.4.3 or later.
2974 * doc/autoconf.texi (Introduction): Likewise.
2975 Reword to avoid some formatting glitches.
2976 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
2977 Clarify explanation of HP compiler bug.
2978 Redo example output tp match current CVS snapshot.
2979 Use @example.org in email addresses when the examples
2980 might get inadvertently cut-and-pasted into user code.
2981 Remove example of autom4te usage that doesn't seem to work now.
2982 Use modern AC_INIT (except when the example is meant to be
2983 shown with Autoconf 2.13).
2984 Update ksh info for Solaris 9 and later.
2985 KB -> kB.
2986 Modernize description of Automake versions a bit.
2987 Don't claim a future version of Autoconf is near.
2988 * doc/install.texi: Reword to avoid some formatting glitches.
2990 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2992 * doc/autoconf.texi: Add [] to examples, so that the manual
2993 follows its own advice about quoting better.
2994 Reword to avoid some formatting glitches.
2995 * doc/installt.exi: Reword to avoid some formatting glitches.
2997 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
2998 Tru64 ksh pattern matching bug. Reported against Libtool by
2999 Albert Chin <libtool@mlists.thewrittenword.com> and
3000 Nicolas Joly <njoly@pasteur.fr>.
3002 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3004 m4_cdr of one-member list was [[]] (one-member list containing an
3005 empty string) instead of [] (an empty list. Callers were skewed to
3006 match this misbehaviour. As a consequence of this:
3007 - m4_foreach([x], [], [foo]) expanded to `foo', while
3008 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
3009 This bug has been fixed:
3011 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
3012 expand to an empty string; print error msg if called without
3013 an argument list.
3014 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
3015 misbehaviour; handle [] and [[]] correctly.
3017 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3019 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

3021 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
3023 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
3025 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
3026 swallow records with more than 99 fields.
3027 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
3028 parse the long line.
3030 2005-06-04 Stepan Kasal <kasal@ucw.cz>
3032 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
3033 swallow literals longer than 399. Reported by Ralf Wildenhues.
3034 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

3037 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
3039 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
3040 to gfortran, and make these the first two compiler names
3041 checked (following the general autoconf preference for gcc).
3043 2005-06-03 Stepan Kasal <kasal@ucw.cz>
3045 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
3046 (DISTCLEANFILES): Remove $(check_SCRIPTS).
3047 (testsuite): Make sure autotest.m4f is up-to-date before using it.

3051 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
3052 expression of unbounded size when processing the --list
3053 option. This runs afoul of a limit of 399 bytes per regular
3054 expression on AIX. Problem reported by Ralf Wildenhues.
3056 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

3059 * doc/autoconf.texi (Particular Headers): Reword example
3060 for multiline stdbool replacement.

3062 give all the details about |#_!!_#|.
3063 Reword description of line replacement.
3065 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3067 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3068 now contain newlines, and substituted files must be referenced on
3069 a line alone; the sed scripts to substitute them are now very
3070 different.
3071 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
3072 commands can be put in a sed script portably.
3073 * doc/autoconf.texi (Setting Output Variables): Document above
3074 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple

3085 * tests/local.at: Don't attempt to check for negated character
3086 classes in shell scripts. The test was too brittle.
3088 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3090 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
3091 * doc/autoconf.texi (Limitations of Builtins): Document this
3092 limitation.
3094 2005-05-24 Stepan Kasal <kasal@ucw.cz>

3104 messages when ac_unique_file is not found.
3105 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
3106 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
3107 commands, for consistency with AC_MSG_ERROR and such.
3109 * bin/autoconf.as: Make more use of "shift 2" in option processing.

3121 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
3122 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
3123 (ac_top_builddir): ... this ...
3124 (ac_top_build_prefix): ... to this; the old name is also kept, for
3125 backward compatibility.
3126 (ac_top_builddir_sub): New variable, without the trailing slash,
3127 always nonempty.
3128 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
3129 * doc/autoconf.texi (Configuration Actions): Rename
3130 ac_top_builddir to ac_top_build_prefix.
3131 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

3142 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3143 argument to m4_foreach. I guess it was necessary in the past,
3144 but I think it's a no-op now.
3146 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3148 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3149 ``cat <<_ACEOF'' commands to one.
3150 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
3151 * lib/autoconf/status.m4: On various places, use expr instead of
3152 ``echo|sed.''
3153 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
3154 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
3155 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
3156 a range.
3157 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
3158 the wrong patterns between ``case'' and ``esac.'' The previous
3159 code had false positives.
3161 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
3163 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
3164 as on 2005-05-02.
3165 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:

3208 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
3209 check.
3210 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
3211 enough arguments, similarly as in m4_bpatsubsts.
3213 2005-05-12 Stepan Kasal <kasal@ucw.cz>
3215 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation

3220 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
3221 for absolute directory names in one loop.
3222 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
3223 abbreviations of --version and --debug.
3225 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
3227 * doc/autoconf.texi (Autoconf Language): Be more precise about
3228 quoting rules. Problems noted by Stepan Kasal.
3229 Also, throughout this document, be more careful about white space.
3230 "blank", "white space", and "space" all have different meanings
3231 and we should be careful to say what we mean.
3233 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
3235 Fix C++ related problems reported by Werner Lemberg.
3236 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
3237 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
3238 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
3239 avoid problems with C++ and throw.
3240 * tests/compile.at: .cpp, not .cc.
3242 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
3244 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3246 * doc/autoconf.texi (Generic Functions): Typos.
3248 2005-05-02 Gary V. Vaughan <gary@gnu.org>
3250 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
3251 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
3252 set by latest automake.
3254 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
3256 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
3257 outputs 0 on GNU/Linux these days.
3259 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
3261 * doc/autoconf.texi (Autoconf Language): Add more description
3262 about quoting heuristics.
3263 (Limitations of Builtins): Describe "set -" problems.
3265 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3267 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
3268 not newline.
3270 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
3271 by AC_DEFINE; it was a mistake.
3272 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
3274 2005-04-25 Stepan Kasal <kasal@ucw.cz>
3276 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
3278 2005-04-22 Stepan Kasal <kasal@ucw.cz>
3280 * doc/autoconf.texi (External Software): Quadrigraphs are not
3281 processed correctly in AS_HELP_STRING; avoid this in the examples.
3282 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
3283 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
3284 comment and reduce m4_default([foo], []) to [foo].
3285 (m4_strip): Update the explanation.
3287 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3289 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
3290 Remove core.conftest.* too; it's generated by Tru64 5.1.
3291 Problem reported by Jennis Pruett.
3292 * lib/autoconf/functions.m4
3293 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3294 Don't bother to remove core files; AC_RUN_IFELSE should do that
3295 for you.
3297 2005-04-19 Stepan Kasal <kasal@ucw.cz>
3299 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
3301 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
3303 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
3304 Report from Horst Wente.
3306 2005-04-15 Stepan Kasal <kasal@ucw.cz>
3308 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
3309 the comment.
3311 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
3313 * doc/autoconf.texi (External Software, Package Options): Add
3314 examples showing how to implement --with-* and --enable-* options.
3316 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
3318 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
3319 as well as configure.in. Problem reported by Gregorio Guidi.
3321 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
3323 * doc/autoconf.texi (Particular Functions): Use gnulib's current
3324 pattern for alloca snippet.
3326 2005-04-04 Stepan Kasal <kasal@ucw.cz>
3328 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

3334 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
3336 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
3337 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
3339 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3341 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
3342 Merge `-z option' as well for the benefit of Solaris link flags. Pass
3343 whole-archive (-zallextract, -zdefaultextract) options in the hope of
3344 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
3345 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
3347 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
3349 * NEWS: The configure command now warns you if you attempt to use
3350 a directory whose name contains a special character like space,
3351 newline, or "\".
3352 * doc/autoconf.texi (Installation Directory Variables): Allow
3353 "," in file names. Do not use \@; it's not a portable regexp.
3354 * bin/Makefile.am (edit): Likewise.
3355 * lib/Makefile.am (edit): Likewise.
3356 * tests/Makefile.am (edit): Likewise.
3357 * tests/semantics.at: Likewise.
3358 * tests/torture.at: Likewise.
3359 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
3360 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
3361 * doc/autoconf.texi (File System Conventions): Warn about
3362 unportable file names.
3363 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3364 (AC_INIT): Use it.
3365 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3366 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3367 ac_pwd, and quote srcdir.
3368 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3370 * doc/autoconf.texi: Fix some systematic formatting problems.
3371 ".)" needs a following @: if not at the end of a sentence, and
3372 similarly for "!)". "etc." should be preceded by a comma.
3373 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3375 2005-03-22 Bruno Haible <bruno@clisp.org>
3377 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3378 argument is often called 'build-aux'.
3380 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3382 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3383 macro AC_TRY_LINK is obsolete.
3384 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3385 `AC_CONFIG_FILES'.
3387 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3389 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3390 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3391 from a Common Lisp's `cl'.
3392 (AC_PROG_CXX): Behave according to the documentation: don't
3393 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3394 make the variable CCC precious; use `cl.exe', not `cl'.
3396 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3397 Alexandre Duret-Lutz <adl@gnu.org>
3399 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3400 /dev/null, as "configure" shouldn't read stdin, and this insulates
3401 us from problems (e.g., when testing for "cl"). Also, do this
3402 redirection before invoking "hostname" or "uname", and keep the
3403 original input stream available via...
3404 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3405 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3406 bother with "</dev/null" since it's now done at the top of
3407 'configure'.
3408 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3409 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3410 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3411 * doc/autoconf.texi (File Descriptor Macros): New section.
3412 (Printing Messages): Mention it.
3413 * tests/base.at (Input/Output): New test.
3415 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3417 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3418 newline if neither \c nor -n work, as that would output two
3419 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3421 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3423 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3424 This causes that any required macros inside will get before the if.
3425 * doc/autoconf.texi (autom4te.cache): A typo.
3427 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3429 Undo previous change, except keep the change to
3430 lib/autoconf/programs.m4 that replaced grep with shell
3431 pattern-matching. This is because net-snmp configure reads stdin.
3432 Reported by Noah Misch.
3434 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3436 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3437 from /dev/null, as "configure" shouldn't read stdin, and this
3438 insulates us from problems (e.g., when testing for "cl").
3439 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3440 before invoking "hostname" or "uname".
3441 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3442 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3443 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3444 "</dev/null" since it's now done at the top of 'configure'.
3445 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3446 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3447 Also, replace grep with shell pattern-matching, to save a process.
3449 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3451 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3452 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3453 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3454 compiler.
3456 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3458 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3459 grep -q isn't portable. Improve grep -s explanation.
3460 Problem reported by Dan Manthey.
3462 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
3464 * doc/autoconf.texi (Special Shell Variables): Clarify
3465 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
3467 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
3469 * doc/autoconf.texi: Use @acronym for DJGPP.
3470 Fix some @code's that should have been @env's, and vice versa.
3471 Sort environment variable names.
3472 Mention that shells no longer inherit IFS.
3473 Don't recommend PATH_SEPARATOR=';' so strongly.
3474 Mention that $RANDOM might expand to the empty string.
3475 "symlink" and "soft link" -> "symbolic link".
3476 Improve mktemp description (reported by Bruno Haible).
3478 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
3480 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
3481 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
3482 Likewise.
3483 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
3484 Likewise.
3486 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
3488 * NEWS: Mention AT_COPYRIGHT.
3490 * tests/local.at (AT_CMP): Use diff directly on input files rather
3491 than copying them.
3493 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
3494 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
3496 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3497 and Paul Eggert <eggert@cs.ucla.edu>
3499 * tests/autotest.at (Empty test suite): New test.
3500 * tests/torture.at (Substitute and define special characters)
3501 (Substitute a 2000-byte string, Define to a 2000-byte string)
3502 (Substitute a newline, Define a newline): New tests.
3504 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3506 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
3507 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
3508 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
3509 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
3510 (Standard regular expressions): New test.
3511 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
3512 excess test name quoting.
3513 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
3514 CPPFLAGS to `configure' instead of setting it in `configure'.
3516 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
3517 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
3518 on some platforms.
3520 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
3521 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
3523 * tests/local.at (AT_CMP): New macro.
3524 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
3525 (AC_SAVE_STATE): Move environment grep...
3526 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
3527 (AT_CONFIG_CMP): New macro.
3528 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
3529 * tests/c.at (Extensions): Do not exit early.
3530 * tests/atlocal.in: Inherit $GREP.
3532 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
3533 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
3535 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
3536 (AC_COPYRIGHT): Factor header comment portion out and move into...
3537 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
3538 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
3539 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
3540 --version output.
3541 * tests/local.at: Add Autoconf test suite copyright notice.
3542 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
3544 2005-02-04 Bruno Haible <bruno@clisp.org>
3545 and Paul Eggert <eggert@cs.ucla.edu>
3547 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
3549 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
3551 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
3552 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
3554 Try not to generated lines of unlimited length, as POSIX places a
3555 2047-byte limit on line length of portable text files.
3556 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
3557 Use newline as a separator, not space.
3558 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
3559 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
3560 space.
3562 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3564 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
3565 as_func_*. Add test to check whether positional parameters
3566 are restored after function return.
3568 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
3570 * doc/autoconf.texi (Special Shell Variables): Mention _,
3571 BIN_SH, DUALCASE. Say that variables other than "status" are safe
3572 if they contain a lower-case letter. The DUALCASE problem was
3573 reported by Ralf Wildenhues.
3575 * bin/autoconf.as: Don't exit with status 0 after write failure
3576 with --help or --version.
3577 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
3578 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
3580 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3582 * doc/autoconf.texi (Limitations of Usual Tools):
3583 Unicos 9 sed limitations.
3584 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
3585 to get the option-enhanced interface on older Crays. Try ftn for
3586 Fortran 95 (newer Crays).
3588 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
3590 * man/Makefile.am (.x.1): Go back to the simple solution, but take
3591 care to echo the commands, so the user knows what's going on.
3592 Modified from a suggestion by Stepan Kasal.
3594 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
3595 with a cross reference. Derived from a suggestion by Bruce Korb.
3597 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
3599 * doc/autoconf.texi (config.status Invocation): Warn about
3600 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
3601 * doc/install.texi (Defining Variables): Likewise.
3602 Based on a proposed patch by Ralf Wildenhues.
3604 * man/Makefile.am (.x.1): Make sure the required generated files
3605 are up to date. Problem and original solution proposed by Stepan Kasal.
3606 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
3607 implicit-man-prerequisites): New rules, used by the above.
3609 * doc/make-stds.texi, doc/standards.texi: Sync from gnulib.
3610 * config/config.guess, config/config.sub, config/install-sh: Likewise.
3611 * config/missing, config/texinfo.tex: Likewise.
3613 2005-01-29 Stepan Kasal <kasal@ucw.cz>
3615 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3616 Update the long comment explaining it.
3618 m4_require no longer writes an ``is required by'' line to the
3619 execution stack. It contains only one bit of non-redundant
3620 information: that the macro was required, not called. And even
3621 this bit is useless in most situations: have you ever met a macro
3622 which both calls and requires the same macro?
3624 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...

4044 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use

4084 * doc/autoconf.texi (Pretty Help Strings): Go back to
4085 single-quoting assignments to cache variables.
4087 2004-11-23 Stepan Kasal <kasal@ucw.cz>
4089 * doc/autoconf.texi (Pretty Help Strings): Fix quoting issues
4090 with the examples; fix the bug in MY_ARG_WITH example reported
4091 by Alexandre Duret-Lutz.
4092 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_ENABLE): Enable
4093 expansion of $1 in the comment emitted to configure.

4103 * doc/autoconf.texi (Autoconf Language): Explain that
4104 ``descriptions'' may not be double quotes.
4105 (Quotation Rule Of Thumb): Likewise.
4106 (Pretty Help Strings): Likewise; remove the wrong comment;
4107 simplify the examples and improve their quoting.
4109 2004-11-13 Stepan Kasal <kasal@ucw.cz>
4111 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
4112 the $1_found variable, don't test whether the file is executable;
4113 Both things are checked ...
4114 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
4115 the former ``test -f''.
4116 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
4118 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>
4120 * doc/autoconf.texi (Limitations of Usual Tools): Avoid cp -r;
4121 use cp -R instead.
4123 2004-11-10 Derek R. Price <derek@ximbiot.com>
4125 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
4126 limitations. Reorder paragraphs for clarity.
4128 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
4130 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
4131 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
4132 variants", "Unix", and some related minor wording fixups.
4134 (Shellology, Special Shell Variables): Document that the Zsh
4135 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
4136 to Alexandre Duret-Lutz for this info.

4147 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
4149 * doc/autoconf.texi (auindex): New macro.
4150 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
4151 Problem reported by Stepan Kasal.
4153 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
4155 Fix problems reported by Andreas Buening in:
4156 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
4157 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
4158 in test makefile.
4159 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
4160 readable; it's not true in OS/2-emx.
4162 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
4164 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
4165 "/usr/include", clear ac_x_includes instead of leaving it as "no"
4166 (trivial change). Problem and patch reported by Andrew Church in:
4167 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
4169 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
4171 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
4172 three args in examples. Problem reported by Frederik Fouvry in:
4173 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
4174 Also, fix some minor spacing and punctuation bugs.
4176 2004-09-02 Akim Demaille <akim@epita.fr>
4178 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
4179 "case" to restore ordering.
4180 Reported by Stepan Kasal.
4182 2004-08-26 Akim Demaille <akim@epita.fr>
4184 * doc/autoconf.texi: Minor typos and stylos.

4190 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
4192 Version 2.59b.
4194 * README: Add advice about m4 1.4.2.
4196 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
4197 texinfo.tex for now (done by hand now).
4198 * Makefile.maint (wget_files, cvs_files):
4199 Remove ansi2knr.c; nobody uses it.
4200 (ansi2knr.c-url_prefix): Remove.
4201 (cvs-update): Fix test for failure. I don't know why it ever
4202 worked...
4204 * doc/autoconf.texi: Update URLs, some of which went stale.
4205 Use @uref rather than @href.
4207 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
4208 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
4210 * config/config.guess, config/config.sub, config/elisp-comp,
4211 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
4212 doc/fdl.texi, doc/standards.texi: Sync with master copy.
4214 * NEWS, TODO, configure.ac, bin/autoscan.in,
4215 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
4216 doc/install.texi, lib/Autom4te/Configure_ac.pm,

4220 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
4221 tests/tools.at, tests/torture.at:
4222 Use "file name" rather than "filename" or "path",
4223 to be consistent with the terminology of the GNU coding standards.
4225 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
4227 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
4228 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
4229 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
4230 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
4232 More fixes to support spaces in the name of the build directory.
4233 This isn't a complete fix but it's an improvement.
4235 * bin/autoconf.as (autom4te_options): New var.
4236 Use it instead of appending to AUTOM4TE, so that we can allow
4237 spaces in the build directory's absolute name.
4238 * bin/autoheader.in ($autoconf): Allow spaces in file names.
4239 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
4240 AT_CHECK_NOESCAPE): Likewise.
4241 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
4242 main program): Likewise.
4244 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
4246 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
4247 From Ralf Corsepius in:
4248 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
4250 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
4252 * doc/autoconf.texi (Function Portability): Document isinf and
4253 and isnan. From a suggestion by Kevin Ryde.
4255 * lib/Autom4te/General.pm (END): Return correct exit status even
4256 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
4258 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
4260 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
4261 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
4262 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
4264 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
4266 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
4267 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
4268 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
4269 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
4270 * lib/autom4te.in (Automake-preselections): Preselect
4271 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4273 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4275 * lib/autom4te.in (Automake-preselections): Preselect
4276 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4277 trace them.
4279 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4281 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4282 Tru64.
4283 * doc/autoconf.texi (Shellology): Mention BIN_SH.
4284 Document problem with "`""`" in pdksh POSIX mode.
4286 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4288 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4289 with pdksh, too. Problem reported by Patrick Welche via
4290 Gary V. Vaughan.
4291 * doc/autoconf.texi (Shellology): Note that set -o posix is
4292 useful for pkdsh, too.
4294 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4296 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
4297 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
4298 Don't fail if ENV or BASH_ENV is readonly.
4299 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4300 etc. are read only. Problem reported by Ludovic Courtes.
4302 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4304 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
4305 zsh, disable GLOB_SUBST to avoid backslash handling problems.
4306 (trivial change)
4308 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4310 * doc/autoconf.texi (File System Conventions): Warn about
4311 names like "aux". Problem reported by Eric Blake.
4313 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4314 by zero instead of array size, so that we can use any arithmetic
4315 constant expression (instead of requiring an integer constant
4316 expression). This allows us to test expressions like DBL_MAX <
4317 LDBL_MAX, which didn't conform to the C standard using the old
4318 method.
4319 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4320 now that we can do floating-point tests at compile time.
4322 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4324 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4325 and LDBL_EPSILON, as the resulting expression isn't an
4326 integer constant expression and violates the C standard.
4327 Problem reported by Nelson H. F. Beebe. Also, check
4328 for "L" suffix, and check that long double doesn't have
4329 worse range or precision than double, that mixed-mode
4330 arithmetic doesn't generate a diagnostic, that double
4331 constants fit in long double.
4333 2004-06-03 Kevin Ryde <user42@zip.com.au>
4335 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4336 malloc(0) and realloc(NULL,size).
4338 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4339 Bob Proulx.
4341 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4343 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4344 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4345 by Jim Meyering.
4347 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4349 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4350 can be rewritten using if-then-else. Suggested by Bruno Haible.
4352 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4354 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4355 Problem reported by Stepan Kasal.
4357 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4359 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4360 change). Patch reported by Ralf Wildenhues in
4361 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4363 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4364 function F exists if the compiler and linker let you compile an
4365 expression like (F != 0). Recent versions of GCC optimize away
4366 the reference to F in that case, since every function address must
4367 be nonzero, so the link succeeds even if F does not exist.
4368 Problem reported by Manu in
4369 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4371 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4372 "Unix". Many uses changed.
4373 (Limitations of Builtins): Explain better why the ! command isn't
4374 portable.
4376 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4378 * lib/autom4te.in (Automake-preselections): Preselect
4379 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4381 2004-05-19 Kevin Ryde <user42@zip.com.au>
4383 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4384 referencing AC_FUNC_STRERROR_R.
4386 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4387 note pessimistic assumption when cross compiling.
4389 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4391 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4392 (until 2004) invoked subcommands with sh -e, contra POSIX.
4393 Reported by Kevin Ryde.
4395 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4397 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4398 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4399 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4400 `test -f " /usr/bin/grep"', which _always_ failed.
4401 (AC_PROG_SED): Ditto bogus PATH fix.
4402 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4403 requires that grep correctly supports _multiple_ `-e' options, rather
4404 than stating only that grep should accept `-e'.
4406 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4408 Port to C99, which requires that 'exit' be declared.
4410 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4411 to ensure that stdlib.h is included.
4412 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4413 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4414 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4415 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4416 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4417 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4418 when using 'exit' in a test; C99 requires that 'exit' be declared.
4420 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4422 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4423 now prefers 'grep' implementations that accept -e.
4424 (Limitations of Usual Tools): Describe problems of traditional
4425 egrep and fgrep with long input lines, and of traditional grep
4426 with -e.
4427 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4428 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4429 All callers changed. Append /usr/xpg4/bin to the PATH, for
4430 Solaris.
4431 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4432 the user with complaints about multiple -e options.
4433 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4434 Define it with AC_PROG_GREP.
4435 * configure.ac (AC_PROG_GREP): Add.
4436 * lib/freeze.mk (GREP): New macro.
4438 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4440 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4441 a possible candidate only after all others fail, rather than
4442 consulting it first. This improves backward compatibility by
4443 better reflecting the way shell selection occurred in previous
4444 versions of Autoconf, and should help to avoid triggering latent
4445 problems in other packages, such as the one in Automake where zsh
4446 is not handled robustly:
4447 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4448 Although it is not Autoconf's responsibility to work around
4449 problems in Automake, it nevertheless makes sense to avoid
4450 introducing unnecessary incompatibilites.
4452 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4453 Gary V. Vaughan <gary@gnu.org>
4455 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4456 how deeply nested we are when a suitable tool is found, set the
4457 ac_path_TOOL_found flag.
4458 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4459 nested we are in this macro. Break out of all 3 nested loops if
4460 ac_path_TOOL_found is set.
4462 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4464 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4465 of the _AS_PATH_WALK loop too if GNU flavor is found.
4467 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4469 * doc/autoconf.texi (Limitations of Make): Update documentation
4470 for `$<'. New entry `Long lines', based on a report from Simon
4471 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4472 paragraph about DJGPP, based on a mail from Richard Dawe.
4474 2004-04-20 Paul Eggert <eggert@twinsun.com>
4476 * tests/c.at (C keywords): Don't assume that GCC supports
4477 "restrict" and "inline", as sufficiently-old GCC versions do not
4478 (also, GCC configured to be in pedantic C89 mode does not).
4479 Problem reported by Sumit Pandya in:
4480 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4482 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4483 consider -g to work if it generates warnings when plain compiles
4484 don't. Problem reported by Braden McDaniel in:
4485 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4487 * doc/autoconf.texi (Slashes): New section, to document a problem
4488 reported by Jim Meyering in:
4489 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
4491 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
4492 linker output files before linking, to work around IRIX 6 linker bug.
4493 Problem reported by Rainer Orth in:
4494 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
4496 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4498 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4499 best tool so far counter rely on the tool path variable name to
4500 avoid checks for one tool being affected by the results of running
4501 the length check on a previous tool.
4503 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4504 match expression argument, as different greps have different
4505 regular expression flavours.
4506 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4507 literals.
4508 (AC_PROG_EGREP): Pass 'EGREP$'.
4509 (AC_PROG_GREP): Pass 'GREP$'.
4511 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
4513 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
4514 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
4516 2004-03-29 Paul Eggert <eggert@twinsun.com>
4518 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
4519 Types, Specific Compiler Characteristics, System Services,
4520 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4521 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4522 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4523 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
4524 Likewise.
4525 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
4526 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
4527 AC_TYPE_OFF_T): Likewise.
4528 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):

4598 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
4599 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than

4626 2004-02-18 Paul Eggert <eggert@twinsun.com>
4628 Fix a dependencies problem, stemming from a Autoconf 2.59 build
4629 problem on QNX reported by Stephen Rasku in
4630 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
4632 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on

4643 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4644 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4645 Darwin uses -lcrt2.o and there's little point to cataloging all
4646 the system variants. Partial fix reported by Andreas Waechter in:
4647 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

4678 (_AS_SHELL_FN_SPY): New macro.
4679 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New

4686 (AS_REQUIRE_SHELL_FN): Require shell functions when
4687 it is used.
4688 (_AS_LINENO_WORKS): Put around braces, we do not
4689 trigger the bash bug anymore.
4690 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
4691 use AS_INIT_WITH_SHELL_FN.
4692 * bin/autoconf.in, tests/wrapper.in: Regenerated.
4694 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

4722 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

4724 the 2003-05-22 change, which removed the older years from the list.
4725 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
4727 2004-01-27 Gary V. Vaughan <gary@gnu.org>

4769 2004-01-26 Paul Eggert <eggert@twinsun.com>
4771 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4772 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4773 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4774 not <inttypes.h>. Problem reported by Tim Mooney in
4775 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
4776 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4777 Likewise.
4779 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4780 otherwise "make check" fails because it forbids cmp (I guess
4781 because cmp treats files as binary on DOS-like systems).
4783 * tests/mktests.sh: Update copyright date to 2004, since some tests
4784 have changed in 2004.
4786 2004-01-23 Gary V. Vaughan <gary@gnu.org>

4789 non-truncating sed or gsed program in PATH.

4792 * NEWS: Updated.
4794 2004-01-15 Paul Eggert <eggert@twinsun.com>
4796 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4797 -std1 disables some useful extensions on Tru64. Problem reported
4798 by N. Lichtmaier in
4799 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
4801 2004-01-14 Paul Eggert <eggert@twinsun.com>
4803 * doc/autoconf.texi (Programming in M4sh): Document that
4804 AS_MKDIR_P succeeds if the destination is a symbolic link
4805 to an existing directory.
4806 (Limitations of Usual Tools): Note that mkdir -p might not
4807 succeed on symlinks to directories.
4809 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
4811 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
4812 * bin/autoheader.in: Grammar fix in message.
4813 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
4814 Test for dir before calling mkdir -p. (trivial changes)
4816 2004-01-13 Eric Blake <ebb9@byu.net>
4818 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
4819 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
4821 2004-01-10 Jim Meyering <jim@meyering.net>
4823 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
4825 2004-01-09 Paul Eggert <eggert@twinsun.com>
4827 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4828 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4829 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4830 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4831 AC_COMPILE_IFELSE, since we now assume our caller invokes
4832 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4833 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4834 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4835 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4837 2004-01-07 Paul Eggert <eggert@twinsun.com>
4839 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4840 `"'...'"`, as it's confusing (and I suspect it may not work on
4841 some platforms). The code was incorrect anyway, as it assumed
4842 that \$ evaluated to itself in that context. Reported by
4843 Alexandre Duret-Lutz.
4845 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
4847 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

4852 * doc/autoconf.texi (One Macro Call): Fix an incorrect
4853 example, and add more examples. Reported by Eric Sunshine.
4855 2004-01-05 Paul Eggert <eggert@twinsun.com>
4857 * doc/autoconf.texi (Limitations of Usual Tools):
4858 Remove warning against "rm -fr" introduced yesterday; it
4859 was a false alarm.
4861 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
4862 autoscan, autoupdate, ifnames): Don't use chmod -w.
4863 * lib/Makefile.am (autom4te.cfg): Likewise.
4864 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
4865 "chmod -w".

4870 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts

4873 2004-01-04 Paul Eggert <eggert@twinsun.com>
4875 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
4876 Use "rm -f" to remove conftest.sed, not plain "rm".
4877 Bug reported by David Relson in
4878 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
4880 * Makefile.am (autom4te-update):
4881 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
4882 * Makefile.maint (my-distcheck, do-po-update): Likewise.
4883 * doc/autoconf.texi (Guidelines): Likewise.

4893 Warn against "rm -fr".

4897 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
4898 -c -o might not work. From a suggestion by Kevin Ryde.
4899 (C Compiler, Generating Sources, Limitations
4900 of Usual Tools, Limitations of Make, Making testsuite Scripts):
4901 Don't put '-o' after non-options, as POSIX doesn't allow this.
4902 Mention that cc's name might be gcc or c89 or whatever.
4904 2004-01-04 Kevin Ryde <user42@zip.com.au>
4906 * doc/autoconf.texi: Add various further index entries.
4908 2003-12-29 Paul Eggert <eggert@twinsun.com>
4910 * bin/autoreconf.in (autoreconf_current_directory):
4911 Fix typo: mkdir without umask arg.
4913 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
4915 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
4916 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
4917 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
4918 explanation clearer.
4920 2003-12-24 Andreas Schwab <schwab@suse.de>
4922 * doc/autoconf.texi (Default Includes): Fix misspelling of
4923 AC_INCLUDES_DEFAULT.

4927 * configure.ac: Test if sh -n works.
4928 * configure: Regenerate.
4929 * tests/atlocal.in: Store the result here.
4930 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
4931 tools.at, looking in atlocal's ac_cv_sh_n_works instead
4932 of explicitly testing.
4933 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
4934 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
4935 * tests/tools.at (Syntax of the shell scripts): Simplify
4936 using AT_CHECK_SHELL_SYNTAX.
4937 (Syntax of the Perl scripts): Remove definition of
4938 AT_CHECK_PERL_SYNTAX.
4940 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
4942 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
4943 stderr to /dev/null.

4950 Extracted from AS_SHELL_SANITIZE.
4951 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
4952 macros.
4953 (AS_SHELL_SANITIZE): Move reinvocation code from
4954 _AS_LINENO_WORKS, use it to find out if shell
4955 functions work.
4956 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
4957 does not work.
4958 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
4959 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

4970 (&sizes): New.
4971 Use them.
4972 No longer rely on Gnus to inline the list of signatures: compute
4973 them on the fly.
4975 2003-11-24 Akim Demaille <akim@epita.fr>
4977 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can
4978 override some files.
4979 (Input): AC_CONFIG_AUX_DIR(aux) is a bad idea on DOS.

5020 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
5021 than $target since the latter is not usual, add guidelines on when to

5026 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

5046 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

5181 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
5182 cross test.
5184 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
5186 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
5187 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

5199 Problems reported by Eric Sunshine.
5201 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5203 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
5204 -mGLOB_options_string stuff for Intel ifc, which can cause
5205 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

5228 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
5229 cache variable instead of $G77 to decide whether to include -O2,
5230 since $G77 is specific to Fortran 77.

5234 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

5239 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
5240 arguments so that it can be used with syntax identical to
5241 AC_PROG_F77, and so that we can more easily decide to
5242 remove/deprecate the DIALECT optional argument in the future if it
5243 proves troublesome.
5244 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
5245 non-freeform-supporting compilers. Document freeform flags.
5247 2003-10-03 Akim Demaille <akim@epita.fr>
5249 * configure.ac: Look for emacs, not macs.

5252 2003-10-03 Akim Demaille <akim@epita.fr>

5259 2003-10-03 Akim Demaille <akim@epita.fr>
5261 * configure.ac: Quotation and formatting changes.

5296 have been created when invoking the compiler.

5310 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
5311 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
5312 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
5314 2003-09-26 Akim Demaille <akim@epita.fr>
5316 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5317 directory for AC_CONFIG_COMMANDS' first argument exists.
5318 This makes valid the invocation of _AC_SRCPATH that follows.
5319 Reported by Eric Sunshine.
5320 * doc/autoconf.texi (Configuration Commands): Adjust.
5322 2003-09-26 Akim Demaille <akim@epita.fr>
5324 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
5325 Reported by Ralf Corsepius.

5329 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
5330 arguments.

5341 2003-09-26 Akim Demaille <akim@epita.fr>
5343 The test suite are sometimes assigning timings incorrectly.
5344 Reported by Henk Krus.
5345 Diagnosed by Nicolas Joly.
5347 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5348 AT_help_all.
5349 Instead of making AT_help a sequence of assignments to grow
5350 $at_help_all, just make AT_help_all be the growing contents of
5351 $at_help_all, and make a single assignment in...
5352 (AT_INIT): here.
5353 (at_times_skip): Flip the meaning and rename as...
5354 (at_times_p): this.
5355 (AT_INIT): When summarizing the test that ran, remove
5356 $at_times_file after use, and check it is present before trying to
5357 use it.

5365 (ifnames): chmod -w.
5366 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5367 executables, not bin/ executables! Otherwise all the magic needed
5368 to find non installed files is turned off. This caused a failure
5369 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5370 as found in its environment (sent by tests/autoreconf): pointing
5371 to bin/autom4te that could not find its files.
5372 * tests/mktests.sh: Force the replacement of generated files, for
5373 the sake of "mv" program that are interactive when overwriting a
5374 -w file.

5385 Trivial change to support GCC's configuration procedure.
5386 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
5387 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
5388 about inconsistency if the preprocessor is set to give errors for
5389 any warning.

5413 2003-09-11 Akim Demaille <akim@epita.fr>
5415 * doc/autoconf.texi (Header Portability): linux/random.h.
5416 From Peter Hendrickson.
5418 2003-09-10 Akim Demaille <akim@epita.fr>
5420 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
5421 willing to edit the output files.
5423 2003-09-10 Akim Demaille <akim@epita.fr>
5425 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
5426 and AC_FC_FREEFORM.
5427 * tests/mktests.sh: Skip AC_FC_SRCEXT.
5428 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

5444 Improve the accuracy of the wording about obsolescence.
5445 From a suggestion by Ian Lance Taylor in
5446 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
5448 2003-09-05 Paul Eggert <eggert@twinsun.com>
5450 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
5451 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
5453 2003-09-04 Akim Demaille <akim@epita.fr>
5455 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
5456 AC_FUNC_WAIT3.
5458 2003-09-04 Akim Demaille <akim@epita.fr>
5460 * bin/autom4te.in: Use &fatal where more appropriate than &error.
5461 (freeze): When exiting, use $exit_code.

5470 Add support for newer Fortran dialects. The F77 interface is
5471 unchanged, and continues to support Fortran 77. New FC macros
5472 correspond to all the old F77 macros, with output variables FC,
5473 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5474 available dialect, but older dialects can be specified. There are
5475 new macros AC_FC_SRCEXT to set the source extension, and
5476 AC_FC_FREEFORM to accept free-form source files.
5478 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
5479 New macros.
5480 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
5481 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
5482 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
5483 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

5490 AC_FC_DUMMY_MAIN, _AC_FC_MAIN, AC_FC_MAIN, __AC_FC_NAME_MANGLING,
5491 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
5492 AC_FC_SRCEXT, AC_FC_FREEFORM):
5493 New macros.
5494 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
5495 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
5496 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
5497 Rewrite in terms of the above.
5498 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
5499 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
5500 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
5501 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.

5505 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
5506 Document problems with timestamp resolution that 'make', 'cp -p', and
5507 'touch -r' have.
5509 2003-08-27 Akim Demaille <akim@epita.fr>
5511 * tests/m4sugar.at (cross_warning): Make sure to enable the
5512 output, so that we can track spurious m4sugar output.
5513 * tests/local.at: Require 2.57.
5514 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5515 are defaulted by AT_CHECK anyway.
5516 Use AT_CHECK_AUTOM4TE.
5517 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
5518 missing dnl.
5520 2003-08-27 Akim Demaille <akim@epita.fr>
5522 * bin/autoheader.in: Issue the "Using auxiliary..." message only
5523 when -Wobsolete is set.
5524 Set it on by default.
5525 Suggested by Klee Dienes.
5527 2003-08-27 Akim Demaille <akim@epita.fr>
5529 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
5530 documentation.
5531 From Guido Draheim.
5533 2003-08-26 Akim Demaille <akim@epita.fr>
5535 * doc/autoconf.texi (Output): Make clear that one can run code
5536 after AC_OUTPUT.
5538 2003-08-25 Akim Demaille <akim@epita.fr>
5540 * config/announce-gen, GNUmakefile, Makefile.maint: Update from

5557 2003-08-22 Akim Demaille <akim@epita.fr>
5559 Version 2.57b.
5561 * Makefile.cfg (local-checks-to-skip): New.
5562 * Makefile.maint (local-check): Rename as...
5563 (local-checks-available): this.
5564 (local-check): New.
5566 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
5567 * configure.ac: Require Automake 1.7.6.
5569 2003-08-22 Akim Demaille <akim@epita.fr>
5571 Output stack traces in warnings.
5573 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
5574 Replace the former...
5575 (m4_warn): Pass the call stack to _m4_warn.
5576 * bin/autom4te.in: Adjust to output the call stack.
5577 * tests/m4sugar.at (m4@&t@_warn): Adjust.
5579 2003-08-22 Akim Demaille <akim@epita.fr>
5581 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
5582 * bin/autom4te.in: Adjust.
5584 2003-08-21 Akim Demaille <akim@epita.fr>
5586 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
5587 (&verbose): Remove.
5588 (&getopt): Adjust the note and verb channels, depending upon
5589 --verbose.
5590 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
5591 * bin/autoupdate.in: Adjust.
5592 Use &verb, not &verbose.
5594 2003-08-21 Akim Demaille <akim@epita.fr>
5596 * bin/autoheader.in (&parse_args): Use &parse_warnings and
5597 &parse_WARNINGS.
5598 ($help): Use Autom4te::ChannelDefs::usage.
5599 * bin/autoscan.in: Use Autom4te::ChannelDefs.
5600 * lib/Autom4te/General.pm: Don't export error: you don't own it.
5602 2003-08-21 Akim Demaille <akim@epita.fr>
5604 First stab at preserving warnings between calls to autom4te,
5605 including when the cache is used.
5607 There are still several issues: (i) there are too many runs of m4
5608 (one for include, one for warnings, and some more), (ii) warnings
5609 spreading on several lines are not handled gracefully, (iii) the
5610 code meant to have the call stack display for errors does not work
5611 (its handling should move from m4 to autom4te).
5613 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5614 Use them.
5615 (@preselect): Add m4_warn.
5616 ($exit_status): Remove, use $exit_code.
5617 ($help): Use Autom4te::ChannelDefs::usage.
5618 (&handle_m4): No longer define the m4_warnings.
5619 At each run, extract and report the warnings.
5620 Always cache the result, including if the exit status is on
5621 failure, since if nothing changes, we should result in the same
5622 failure, hence we can use the cache.
5623 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5624 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5625 Remove.
5626 (m4_warn): Redefine as a do-nothing: it is its invocation that
5627 matters, as warnings are now reported via traces.
5628 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5629 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5630 the latter reveals calls to the former.
5632 Adjust the tests.
5634 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
5636 2003-08-21 Akim Demaille <akim@epita.fr>
5638 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
5639 Use them.
5641 2003-08-21 Akim Demaille <akim@epita.fr>
5643 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
5644 forward order.
5645 * lib/Autom4te/ChannelDefs.pm: Doc typos.
5646 (&parse_warnings): Accept a list of warning requests.
5647 (&usage): Return a string, not a side effect.
5648 (cross): New warning category.
5650 2003-08-21 Akim Demaille <akim@epita.fr>
5652 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
5653 (&require_configure_ac): Accept an optional directory argument.
5654 ($configure_ac): Remove.
5655 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
5656 (&catfile): Remove.
5657 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
5658 * bin/autoscan.in: Adjust.
5660 2003-08-20 Akim Demaille <akim@epita.fr>
5662 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
5663 Reported by Alexandre Duret-Lutz.
5665 2003-08-20 Akim Demaille <akim@epita.fr>
5667 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
5668 * bin/autom4te: Adjust.
5669 In particular, be Autoconf tools are really silent when properly
5670 working, bind the verbosity of the 'note' channel to $verbose.
5671 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5672 (&xsystem, &contents): Remove, since they are exported by...
5673 * lib/Autom4te/FileUtils.pm: this.
5674 More perldoc.
5675 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
5676 * lib/Autom4te/FileUtils.pm: here.
5678 2003-08-20 Akim Demaille <akim@epita.fr>
5680 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
5681 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
5682 from CVS Automake.
5684 2003-08-20 Akim Demaille <akim@epita.fr>
5686 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
5687 (autom4te-update): New.

5704 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
5706 * lib/autom4te.in (Automake-preselections): Preselect
5707 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
5708 and m4_sinclude.
5710 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>

5714 * doc/autoconf.texi (autom4te Invocation): Mention
5715 Autoconf-without-aclocal-m4.

5731 2003-08-14 Derek Price <derek@ximbiot.com>
5733 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
5734 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
5735 shorter column three. Add DESCRIPTION to log file content.
5737 2003-08-13 Derek Price <derek@ximbiot.com>
5739 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
5740 output.
5742 2003-08-12 Derek Price <derek@ximbiot.com>
5744 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
5745 (AT_CHECK_NOESCAPE): Move core functionality to...
5746 (_AT_CHECK): ...this new macro.
5748 2003-08-07 Derek Price <derek@ximbiot.com>
5750 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
5751 (AT_CHECK_NOESCAPE): ...to this new macro.
5753 2003-07-31 Paul Eggert <eggert@twinsun.com>
5755 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
5756 in Bash 2.01. Problem reported by Brian Gough in
5757 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
5759 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
5761 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
5762 -lcrt1.o, for OS X. (trivial change)
5764 2003-07-07 Paul Eggert <eggert@twinsun.com>
5766 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
5767 inside '#ifndef __cplusplus'. Problem reported by
5768 Bob Friesenhahn.
5770 2003-07-06 Bill Clarke <llib@computer.org>
5772 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
5773 'long', not 'int', for benefit of Sun's recent C++ compilers
5774 (trivial change). See:
5775 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
5776 (This really should be 'intptr_t', not 'long', but that would
5777 take more work.)
5779 2003-06-25 Akim Demaille <akim@epita.fr>
5781 * lib/Makefile.am (autom4te.cfg): Make it read only.
5782 Depend on Makefile since it contains substitutions.
5783 From Paolo Bonzini.
5784 * lib/autom4te.in (args): Add local.at? for Autotest args.
5785 This change was made on autom4te.cfg which is generated.
5786 Reported by Raja R. Harinath.
5788 2003-06-25 Akim Demaille <akim@epita.fr>
5790 * doc/autoconf.texi (Header Portability): sys/mount.h.
5791 From Gareth McCaughan.
5793 2003-06-23 Akim Demaille <akim@epita.fr>
5795 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5796 not all of them. This fixes 1. the fact that when testing
5797 Autoconf there are many many config.log, 2. the incorrect use of
5798 top_srcdir to find config.log.
5799 Don't mix the detailed output of failed test with the summary of
5800 failures. Rather, append detailed log afterwards.
5802 2003-06-23 Akim Demaille <akim@epita.fr>
5804 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
5805 always run: output config.log on $at_group_log.
5807 2003-06-23 Akim Demaille <akim@epita.fr>
5809 * tests/torture.at (#define header templates): Don't use quotes in
5810 C++ comments as it puzzles Emacs' sh font-lock-mode.
5812 2003-06-23 Akim Demaille <akim@epita.fr>
5814 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
5815 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
5816 * tests/atspecific.m4: Rename as...
5817 * tests/local.at: This.
5818 * tests/suite.at: Move the globals into...
5819 * tests/local.at: here.
5820 * tests/Makefile.am: Adjust.
5821 * doc/autoconf.texi (testsuite Scripts): Adjust.
5823 2003-06-21 Kevin Ryde <user42@zip.com.au>
5825 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
5826 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
5827 ensuring we add -std1 for full-ANSI.
5829 * doc/autoconf.texi (hdrindex): New macro.
5830 Add index entries for portability of various standard header files.
5832 2003-06-20 Akim Demaille <akim@epita.fr>
5834 * configure.ac: Bump to 2.57b.
5836 2003-06-20 Akim Demaille <akim@epita.fr>
5838 Version 2.57a.
5840 2003-06-20 Akim Demaille <akim@epita.fr>
5842 * bin/autom4te.in: Don't rely on $HOME being defined.
5843 Reported by Marc Espie as PR/233.
5845 2003-06-20 Akim Demaille <akim@epita.fr>
5847 * lib/autotest/general.m4: Use at_times_file only if used.
5848 From Nicolas Joly.
5850 2003-06-20 Akim Demaille <akim@epita.fr>
5852 * config/config.guess, config/config.sub, config/elisp-comp,
5853 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
5854 Update from masters.
5856 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
5858 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
5859 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
5860 (TEST_SCRIPT): New diversion.
5861 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
5862 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
5863 (AT_INIT): Support for expected failures.
5865 2003-06-02 Akim Demaille <akim@epita.fr>
5867 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
5868 changes.
5869 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
5870 Autoconf nor Automake.
5871 (&contents): New, from Automake.
5872 PODify.
5874 2003-05-28 Paul Eggert <eggert@twinsun.com>
5876 * NEWS, doc/autoconf.texi (Particular Functions),
5877 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
5878 is the inverse of localtime.
5880 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
5882 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
5883 (handle_exec_errors): New function. Work around $! being
5884 altered by WEXITSTATUS.
5885 (xqx, xsystem): Use handle_exec_errors.
5887 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
5889 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
5890 Do not call `_exit()', simply modify `$?'.
5891 (xsystem): Reset $! before running system, and check it afterward.
5892 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
5893 63 for version mismatches.
5895 2003-05-23 Akim Demaille <akim@epita.fr>
5897 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
5898 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
5899 the middle of a line).
5900 * lib/m4sugar/m4sugar.m4: Likewise.
5901 Remove useless spaces in comments.
5903 2003-05-23 Akim Demaille <akim@epita.fr>
5905 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
5906 exit 63, so that we (or Automake's "missing") can tell the
5907 difference with a plain failure.
5908 * doc/autoconf.texi (Notices): Adjust.
5910 2003-05-23 Akim Demaille <akim@epita.fr>
5912 * Makefile.am, bin/Makefile.am, config/Makefile.am,
5913 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
5914 White spaces cleanup.
5916 2003-05-22 Jim Meyering <jim@meyering.net>
5917 Paul Eggert <eggert@twinsun.com>
5919 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
5920 Remove `#include <stdlib.h>' from the list; we should never
5921 make confdefs.h include <stdlib.h> or <cstdlib>, because the
5922 resulting namespace pollution would cause other tests to fail.
5923 Configure scripts run with some older versions of g++ and HP's
5924 aCC would fail due to such an #include. Problems reported by
5925 Matthew Mueller in <http://bugs.debian.org/120704> and by
5926 Keith Bostic in
5927 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
5928 In the test, use the test declaration before including <stdlib.h>,
5929 as that's closer to how it'll be used.
5931 2003-05-23 Akim Demaille <akim@epita.fr>
5933 * doc/autoconf.texi (Header Portability): ucred.h.
5934 From Ian Redfern.
5936 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5938 Overhaul Autotest's logging: generate separate log files
5939 in testsuite.dir/NNN/testsuite.log, and append them to
5940 testsuite.log instead of re-running the test verbosely.
5942 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
5943 file descriptor, write 0 to at_status_file instead of setting
5944 at_status=0, initialize some new variables (at_status_file,
5945 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
5946 to rerun the tests, instead append the at_group_log to the
5947 at_suite_log when a test fails.
5948 (AT_SETUP): pipe the test case's output into at_tee_pipe,
5949 with the AS_MESSAGE_LOG_FD redirected to stdout.
5950 (AT_CLEANUP): save the output status in $at_status_file
5951 and restore it, redirect the AS_MESSAGE_LOG_FD back to
5952 its original place.
5953 (AT_CHECK): since tests are run with a redirected stdout,
5954 and used to be re-run in verbose mode, turn some $at_verbose
5955 into echo, and don't redirect the output of testing stdout
5956 and stderr.
5958 * lib/autotest/autoconf.texi (testsuite Scripts): Update

6077 and truncate.
6079 2003-05-06 Akim Demaille <akim@epita.fr>
6081 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6082 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6083 by aclocal.m4 is changed it might require the importing of another
6084 m4 extension file, i.e., aclocal must be run.
6086 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6087 (&parse_args): Use --force with aclocal if required and supported.

6097 open during the whole autom4te run.
6098 ($icache_file): New.
6099 (&freeze): Lock the $icache_file.
6101 2003-04-29 Derek Price <derek@ximbiot.com>
6103 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the

6109 to support the new --keywords behavior.
6111 2003-04-27 Karl Berry <karl@freefriends.org>
6113 * doc/autoconf.texi: Make the dir entries in the autoconf manual
6114 align better with others. I also made some of the individual
6115 entries on one line, for brevity and to make it easier for me to

6340 gettimeofday and many other functions.
6342 2002-12-03 Paul Eggert <eggert@twinsun.com>

6354 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
6356 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
6357 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6358 defined, to support freestanding compilers. This should fix the
6359 bug reported by Momchil Velkov in
6360 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6362 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty

6398 * Makefile.maint: Sync with Bison, i.e.:
6399 (po-check): Scan .l and .y files instead of the
6400 .c and the .h files that they generate. This fixes the bug
6401 reported by Tim Van Holder in:
6402 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6403 Look for N_ as well as for _. Try to avoid matching #define for
6404 N_ and _.

6460 2002-11-05 Akim Demaille <akim@epita.fr>
6462 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6463 Remove.
6464 We _have_ to stop using the old compatibility scheme that tried to
6465 avoid useless backslashes because Libtool 1.4.3 contains a
6466 AC_DEFINE([error_t], [int],
6467 [Define to a type to use for \`error_t' if it is not
6468 otherwise available.])
6469 We _have_ to quote the single quote and backslashes with \. The
6470 old compatibility scheme saw that ` was backslashed, and therefore
6471 did not quote the single quote. Hence before this patch, Autoconf
6472 was not compatible with Libtool.
6474 2002-11-04 Paul Eggert <eggert@twinsun.com>
6476 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

6863 Reported by Alexandre Duret-Lutz.
6865 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

6885 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report

6926 * bin/autoreconf.in (&autoreconf): Run autopoint before the first

6928 aclocal.
6929 Instead of blindly running autopoint, scan configure.ac (not the
6930 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
6931 Reported by Paul D. Smith.
6933 2002-10-08 Paul Eggert <eggert@twinsun.com>
6935 Work around problems found when POSIXLY_CORRECT=1 is set.
6936 None of this seems to have anything to do with POSIX, really,
6937 but it's how Perl getopt works.
6938 * bin/autom4te.in (parse_args): Configure GetOpt with
6939 "permute", too.
6940 * doc/autoconf.texi (Invoking autom4te):
6941 --warning -> --warnings.
6942 * lib/autom4te.in: --warning -> --warnings.
6944 2002-09-28 Akim Demaille <akim@epita.fr>
6946 * doc/autoconf.texi (autom4te.cache): New section.
6948 2002-09-28 Akim Demaille <akim@epita.fr>
6950 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
6951 (Automake-preselections): Update.

6958 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
6959 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
6961 2002-09-28 Akim Demaille <akim@epita.fr>
6963 * tests/torture.at (Configuring subdirectories): Be robust to
6964 users who use config.site to require for a cache: in this case,
6965 the two last configure runs, using two different sets of
6966 arguments, trigger a legitimate error.
6968 2002-09-28 Akim Demaille <akim@epita.fr>
6970 * tests/m4sh.at (Functions Support, Functions and return Support):
6971 New.
6973 2002-09-28 Akim Demaille <akim@epita.fr>
6975 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
6976 autoheader are Perl programs.
6977 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
6978 (autom4te): Specify that the sources are in the $srcdir.
6979 * doc/autoconf.texi (Installation Directory Variables): Adjust.
6981 2002-09-28 Akim Demaille <akim@epita.fr>

6984 (tm_zone): Move their rules to...
6985 * lib/autoconf/types.m4: here, using AN_ macros.
6986 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
6987 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
6988 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
6989 * lib/autoconf/programs.m4: here.
6990 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
6991 (ETAGS_FOR_AUTOCONF): New.
6992 Use it.
6994 2002-09-28 Akim Demaille <akim@epita.fr>
6996 * lib/autoconf/autoscan.m4: New file.
6997 * lib/autoconf/autoconf.m4: Include it.
6998 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
6999 that were listed in the original autoscan.list.
7000 * lib/autoconf/headers.m4: Similarly with headers.
7001 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
7002 (.m4.m4f): Don't pass --prepend-include, since that's done by
7003 tests/autom4te itself.
7004 * lib/autoscan/Makefile.am: Include freeze.mk.
7005 (autoscan.list): New target --this file is no longer a source.
7006 (autoscan.pre): New file.
7008 2002-09-28 Akim Demaille <akim@epita.fr>
7010 * bin/autoscan.in (@kinds): Make them singular.
7011 Adjust all uses.
7012 (&init_tables): When --debug, report the list of rules to ease
7013 tracking changes in autoscan.list.
7014 * lib/autoscan/autoscan.list (function): Strip comments, sort.
7016 2002-09-28 Akim Demaille <akim@epita.fr>
7018 * lib/autoscan/functions, lib/autoscan/headers,
7019 * lib/autoscan/identifiers, lib/autoscan/makevars,
7020 * lib/autoscan/programs: Merge into...
7021 * lib/autoscan/autoscan.list: this.
7022 * bin/autoscan.in (&init_tables): Adjust.
7024 2002-09-28 Akim Demaille <akim@epita.fr>
7026 * lib/autoscan/functions, lib/autoscan/headers,
7027 * lib/autoscan/identifiers, lib/autoscan/makevars,
7028 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
7029 `functions' line is now prefixed with `function:'.
7030 * bin/autoscan.in (&init_tables): Adjust.
7032 2002-09-28 Akim Demaille <akim@epita.fr>
7034 From now on, autoscan files must always map a macro name to a
7035 word: there is no `default' macro for autoscan.
7037 * bin/autoscan.in (&init_tables): Reject entries with no macro at
7038 all.
7039 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
7040 explicit.
7042 2002-09-28 Akim Demaille <akim@epita.fr>
7044 * bin/autoscan.in (%c_keywords): Remove.
7045 (&used): Keep only track of the words we might be interested in.
7046 (&output_kind): It is no longer needed to look for non active
7047 checks.
7049 2002-09-27 Akim Demaille <akim@epita.fr>
7051 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
7052 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
7053 * lib/autoscan/functions: Adjust.
7054 * doc/autoconf.texi (Particular Functions): Adjust.
7056 2002-09-27 Akim Demaille <akim@epita.fr>
7058 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
7059 from /tmp.
7060 Thanks to Bill Moseley and Paul Eggert.
7061 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
7062 the tmpdir must be created.
7063 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
7064 dir be in the build tree, instead of $TMPDIR.
7066 2002-09-27 Akim Demaille <akim@epita.fr>
7068 * bin/autoscan.in: Improve the comments.
7069 (&parse_args): Drop obsolete undocumented options.
7070 (&output_kind): Output warnings.
7071 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
7072 (getwd): Trigger a warning.
7074 2002-09-26 Akim Demaille <akim@epita.fr>
7076 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
7077 Reported by Ralf Corsepius.
7078 * doc/autoconf.texi (autoreconf Invocation): Likewise.
7080 2002-09-26 Akim Demaille <akim@epita.fr>
7082 Single suffix rules and seperated dependencies are not portable.
7084 * doc/autoconf.texi (Installation Directory Variables): Update.
7085 (Limitations of Make): Some about `Single Suffix Rules and
7086 Separated Dependencies'.
7087 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7088 (ifnames, autoscan, autom4te): Un-factor into several rules.
7090 2002-09-25 Paul Eggert <eggert@twinsun.com>
7092 * BUGS (Interoperability bugs): New section. Mention libtool
7093 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
7095 2002-09-24 Paul Eggert <eggert@twinsun.com>
7097 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
7098 make handles suffix-rules differently from GNU make.
7100 * bin/Makefile.am (SUFFIXES, .in): Remove.
7101 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
7102 Move the body of the old .in rule here.
7104 2002-09-16 Akim Demaille <akim@epita.fr>
7106 i960 compilers create `b.out' files by default.
7107 Reported by Ralf Corsepius.
7109 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
7110 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
7112 2002-09-13 Paul Eggert <eggert@twinsun.com>
7114 * doc/autoconf.texi (Particular Headers): Remove obsolete
7115 reference to `struct timezone' in the description of
7116 AC_HEADER_TIME.
7118 2002-09-13 Akim Demaille <akim@epita.fr>
7120 Version 2.54.
7122 * config/config.sub, config/config.guess: Update.
7123 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
7124 * Makefile.am: Adjust.
7126 2002-09-13 Akim Demaille <akim@epita.fr>
7128 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
7129 reading config.log when the compiler is rejected.
7130 Suggested by Guido Draheim.
7132 2002-09-13 Akim Demaille <akim@epita.fr>
7134 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
7135 (chdir_init) might hang when stat'ing mounted directories.
7136 Reported by Vance Shipley.
7138 2002-09-12 Akim Demaille <akim@epita.fr>
7140 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
7141 the lists.
7143 2002-09-12 Akim Demaille <akim@epita.fr>
7145 * doc/autoconf.texi (Defining Symbols): Present two different
7146 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
7147 difference between 1 argument calls, and 2-3 argument calls.
7149 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
7151 * doc/autoconf.texi: Review grammar and punctuation.
7153 2002-09-11 Paul Eggert <eggert@twinsun.com>
7155 * doc/autoconf.texi: Fix minor formatting, spelling, and
7156 grammatical typos.
7157 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
7158 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
7159 is obsolescent.
7161 2002-09-11 Akim Demaille <akim@epita.fr>
7163 * doc/autoconf.texi (Questions): Rename as...
7164 (FAQ): this.
7165 (Defining Directories): New.
7167 2002-09-09 Akim Demaille <akim@epita.fr>
7169 * doc/autoconf.texi (Making testsuite Scripts): Update.
7170 Suggested by Nishio Futoshi.
7172 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
7174 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
7175 plain `@' is wanted.
7177 2002-09-09 Akim Demaille <akim@epita.fr>
7179 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
7180 `duplicates', since the algorithm was too naive and could keep
7181 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7182 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7183 Reported by Ralf Corsepius.
7184 * tests/torture.at (Configuring subdirectories): Exercise these
7185 cases.
7187 2002-09-09 Akim Demaille <akim@epita.fr>
7189 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
7190 looking for a replacement file.
7191 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
7192 directory is relative.
7193 * doc/autoconf.texi (Generic Functions): Clarify the replacement
7194 directory definition.
7195 Reported by Andreas Schwab and Jim Meyering.
7197 2002-09-06 Akim Demaille <akim@epita.fr>
7199 * doc/autoconf.texi (Setting Output Variables): Clarify what
7200 precious variables are.
7201 Suggested by Pontus Skoeld.
7203 2002-09-05 Akim Demaille <akim@epita.fr>
7205 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7206 (ifnames, autoscan, autom4te): Since we don't only depend on
7207 configure.ac variables (such as VERSION etc.), but also on prefix
7208 and so forth, depend on Makefile, not configure.ac.
7209 Reported by Alexandre Duret-Lutz.
7210 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7212 2002-09-05 Kevin Ryde <user42@zip.com.au>
7214 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
7215 doesn't seem to be confined to ia64, just say "some versions".
7217 2002-09-04 Akim Demaille <akim@epita.fr>
7219 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
7220 Automake 1.6c.
7221 * Makefile.am (maintainer-clean-local): Remove.
7222 (MAINTAINERCLEANFILES): Remove COPYING.
7224 2002-09-03 Paul Eggert <eggert@twinsun.com>
7226 * doc/autoconf.texi (Configuration Commands): Remove obsolete
7227 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
7228 Brinkmann.
7230 2002-09-03 Akim Demaille <akim@epita.fr>
7232 * configure.ac: Bump to 2.53d.
7233 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
7234 as of today, on Automake's team suggestion.
7236 2002-09-03 Akim Demaille <akim@epita.fr>
7238 Version 2.53c.
7240 2002-09-02 Akim Demaille <akim@epita.fr>
7242 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
7243 SITE_MACRO_DIR.
7244 * configure.ac: Disable SITE_MACRO_DIR.
7246 2002-09-02 Jim Meyering <meyering@lucent.com>
7248 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
7249 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
7250 Also, tweak grammar: s/make sure to/be sure to/.
7252 2002-09-02 Paul Eggert <eggert@twinsun.com>
7254 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
7255 directory names are generally preferable to physical names.
7257 2002-09-02 Akim Demaille <akim@epita.fr>
7259 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7260 Reported by Raja R. Harinath.
7261 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7262 * bin/autoupdate.in: Use error instead of die.
7264 2002-09-01 Paul Eggert <eggert@twinsun.com>
7266 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7267 ordinary shell concatenation rather than echo+tr+sed command that
7268 runs afoul of a long-line-related sed bug in Solaris 8.
7270 * bin/autoheader.in (parse_args): --warning -> --warnings.
7272 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7273 stdout, as traditional "ls" does.
7274 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7275 _AC_COMPILER_EXEEXT_O): Likewise.
7276 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7278 * bin/autoconf.as: Add --prepend-include option. This patch was
7279 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7280 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7282 * bin/autoconf.in, configure: Regenerate.
7284 * doc/autoconf.texi (Special Shell Variables): Mention
7285 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7287 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7288 MAILPATH and set PS1, PS2, PS4 to default values, to work
7289 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7290 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7291 the Autoconf documentation specifies; fall back to "unset" only if
7292 this fails. Use a shell for-loop for this rather than an m4 loop,
7293 to shorten the output script.
7295 2002-08-30 Paul Eggert <eggert@twinsun.com>
7297 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7298 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7299 for the CDPATH problem. Document PWD.
7300 (Limitations of Builtins): Document the problem that "cd $foo" and
7301 "ls $foo" may refer to different directories in shells conforming
7302 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7303 example, since the old example is now out of date.
7305 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7306 FOO" and "ls FOO" talk about different directories; this catches
7307 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7308 spaghetti.
7310 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7311 of rolling our own unset.
7312 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7313 in practice we needn't worry about CDPATH if unset doesn't work.
7315 * Makefile.in, aclocal.m4, bin/Makefile.in,
7316 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7317 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7318 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7319 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7320 tests/Makefile.in: Regenerate with Automake 1.6.3.
7322 * config/config.guess, config/config.sub, config/mkinstalldirs:
7323 Update.
7325 * configure: Regenerate with self.
7327 2002-08-30 Kevin Ryde <user42@zip.com.au>
7329 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7330 default output.
7332 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7334 * bin/autom4te.in (Request::load): Correctly test for "do" read
7335 failure.
7337 2002-08-29 Akim Demaille <akim@epita.fr>
7339 * lib/Autom4te/General.pm (&xqx): New.
7340 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7341 hand, which is not portable.
7342 (&error): New.
7343 * bin/autom4te.in: Use them.
7344 Use &error instead of die.
7345 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7346 Adjust.
7348 2002-08-17 Paul Eggert <eggert@twinsun.com>
7350 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7351 default list of compilers to try, since it was long ago superseded
7352 by the ksh fc builtin. Suggested by Steven G. Johnson.
7354 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7356 * doc/autoconf.texi (Invoking autom4te): End the option table,
7357 fixing a bug introduced by the previous patch.
7358 (Limitations of Make): Add a 'target lookup' subentry in the
7359 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
7361 2002-07-29 Mark D. Roth <roth@feep.net>
7363 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
7364 options and use $AUTOM4TE_PATH.
7365 * doc/autoconf.texi: Remove documentation of autom4te
7366 --include-envvar and --site-macro-subdir options and document
7367 use of $AUTOM4TE_PATH.
7368 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
7369 arguments from each language section.
7371 2002-07-29 Paul Eggert <eggert@twinsun.com>
7373 * doc/install.texi: Include copyright symbol in copyright notice.
7375 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7376 Replace with:
7377 (AM_MAKEINFOFLAGS): New macro.
7378 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7379 * Makefile.am (INSTALL): Use the new macros.
7380 Use -o rather than --output, since "missing" does not grok --output.
7382 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7384 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7385 comments do not always work. Never trust the exit status of
7386 `make -k'.
7388 2002-07-24 Kevin Ryde <user42@zip.com.au>
7390 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7391 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
7393 2002-07-23 Paul Eggert <eggert@twinsun.com>
7395 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
7396 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
7397 apparently treats PATH="nonexistent" as if it contained ".".
7398 Bug reported by Stefan `Sec' Zehl.
7400 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7402 * doc/autoconf.texi (Limitations of Make): Mention the special
7403 handling of the obj/ directory by BSD make.
7405 2002-07-20 Kevin Ryde <user42@zip.com.au>
7407 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
7408 backslashes.
7410 2002-07-19 Akim Demaille <akim@epita.fr>
7412 * doc/autoconf.texi (Function Portability): `exit'.
7413 (Programming in M4sh): Ethymology of M4sh.
7415 2002-07-19 Akim Demaille <akim@epita.fr>
7417 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.

7522 so that Emacs setups GNU style for perl-mode and cperl-mode.
7524 2002-06-27 Paul Eggert <eggert@twinsun.com>
7526 * config/install-sh: Quote $src. Prefer || to test's -o option,
7527 as per "Limitations of Builtins".
7528 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
7529 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
7531 * tests/mktests.sh: Use grep instead of fgrep, as per

7559 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>

7576 2002-06-07 Akim Demaille <akim@epita.fr>
7578 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
7579 rename as...
7580 (AC_REPLACE_FNMATCH): this.
7581 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
7582 AC_FUNC_FNMATCH_GNU.
7584 2002-06-07 Akim Demaille <akim@epita.fr>
7586 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
7587 Rosetta Stone for Unix.
7589 2002-06-07 Akim Demaille <akim@epita.fr>
7591 * bin/autom4te.in (warn_forbidden): When rejecting a token,
7592 suggest m4_pattern_allow.
7593 Suggested by Adam J. Richter.
7595 2002-06-07 Akim Demaille <akim@epita.fr>
7597 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize

7604 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
7605 (AC_REPLACE_FNMATCH_GNU): these.
7606 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
7607 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
7608 * tests/mktests.sh (ac_exclude_list): Don't check

7613 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp

7621 * config/config.guess, config/config.sub, config/texinfo.tex:
7622 Update from masters.
7624 2002-05-29 Paul Eggert <eggert@twinsun.com>
7626 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
7627 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
7628 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):

7651 2002-05-23 Akim Demaille <akim@epita.fr>
7653 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
7654 version of Autoconf that is discussed.
7656 2002-05-22 Paul Eggert <eggert@twinsun.com>
7658 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
7659 from the default list of compilers to try. Suggested by
7660 Kate Hedstrom.
7661 * NEWS: Document the above.
7662 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
7664 2002-05-17 Paul Eggert <eggert@twinsun.com>
7666 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
7667 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
7668 This improves on an earlier suggestion by H. Peter Anvin.
7670 2002-05-16 Paul Eggert <eggert@twinsun.com>
7672 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7673 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7674 Both macros now accept an optional source-dir arg.
7675 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7677 * NEWS: Document this.
7678 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7680 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7681 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
7682 not for GNU extensions; this undoes part of the 2000-11-03 change,
7683 reverting to 2.13-compatible behavior.
7684 Add new optional argument DIR.
7685 (AC_FUNC_FNMATCH_GNU): New macro.
7687 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
7689 2002-05-08 Paul Eggert <eggert@twinsun.com>
7691 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7692 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7693 and it causes a 'test' syntax error if it fails.
7694 Bug reported by Stephen Gildea.
7696 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7697 If prototypes are supported, use them to check this at compile-time,
7698 instead of trying to check it at run-time. If we must do a run-time
7699 check, assume that setvbuf is standard when cross-compiling, as
7700 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7701 Bug reported by Paul D. Smith.
7703 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7704 argument specifying location of getloadavg.c. This removes a
7705 FIXME. This idea was taken from Jim Meyering's implementation in
7706 textutils.
7707 * doc/autoconf.texi (Particular Functions): Document this.
7708 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7709 that's what the code does; this fixes a bug reported by
7710 Paul D. Smith.
7712 2002-05-03 Akim Demaille <akim@epita.fr>
7714 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
7715 autopoint instead of gettextize.
7716 ($uses_alocal): Rename as...
7717 ($uses_aclocal): this.
7718 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7719 Suggested by Bruno Haible.
7721 2002-05-03 Akim Demaille <akim@epita.fr>
7723 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
7725 2002-04-29 Paul Eggert <eggert@twinsun.com>
7727 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7728 files to be 1 second older; just set them to be the same time.
7729 Also, sleep 1 second after the first aclocal, to work around
7730 problems with sub-second time stamps on the input files.
7732 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7734 * doc/autoconf.texi: Mention "set -e -x" lossage
7735 under node "Limitations of Builtins".
7737 2002-04-29 Akim Demaille <akim@epita.fr>
7739 * doc/install.texi: Better wording for setting variables when
7740 running configure.
7741 From Christian Cornelssen.
7743 2002-04-29 Akim Demaille <akim@epita.fr>
7745 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7746 of lack of $LINENO support, then the test will compare the $LINENO
7747 in testsuite vs. the lineno in the test file. This is wrong, of
7748 course.
7749 Be sure to protect it.
7750 Reported by Patrick Welche.
7752 2002-04-25 Akim Demaille <akim@epita.fr>
7754 * doc/autoconf.texi (Obsolete Macros): Typo.
7755 Reported by Vladimir Volovich.
7757 2002-04-25 Akim Demaille <akim@epita.fr>
7759 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7760 than some of the input files, hence, on the second run of aclocal,
7761 if some of its input are younger, make them older.
7762 Suggested by Paul Eggert.
7764 2002-04-25 Akim Demaille <akim@epita.fr>
7766 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
7767 Thanks to Paul Eggert.
7769 2002-04-25 Akim Demaille <akim@epita.fr>
7771 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
7772 and ac_subst_vars be sh variables containing the list of
7773 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7774 DEFAULT diversion.
7775 (_AC_INIT_PREPARE): Use them to log them.
7776 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7777 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7778 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7779 _AC_SUBST_FILES and _AC_SUBST_VARS.
7780 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
7782 2002-04-24 Akim Demaille <akim@epita.fr>
7784 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7785 autoheader, so that automake does not complain about a missing
7786 config.h.in that was to be created.
7788 2002-04-23 Akim Demaille <akim@epita.fr>
7790 * bin/autoheader.in (parse_args): --warning takes an argument.
7791 Fixes PR/220.
7793 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
7795 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

7806 2002-04-22 Akim Demaille <akim@epita.fr>
7808 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
7809 comma.
7810 Reported by Gregory Giannoni.
7812 2002-04-22 Akim Demaille <akim@epita.fr>
7814 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
7815 Fixes false failures on Darwin.
7817 2002-04-21 Paul Eggert <eggert@twinsun.com>

7821 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

7840 Minor spelling and grammar fixes.
7842 * doc/autoconf.texi: Follow the outline suggested in the GNU
7843 Sample Texts sections of the Texinfo 4.2 manual. Most
7844 importantly, this makes sure that the copyright notices appear in
7845 all output formats. You probably need Texinfo 4.2 to generate
7846 the manual now.

7869 * tests/c.at: We can't have zero arguments, so remove workaround
7870 that is not portable to Zsh.
7872 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
7874 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

7886 From Oliver Kiddle and Peter Stephenson.
7888 Have M4sh perform minimal shell sanitizing.
7890 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'

7897 Adjust Autoconf and Autotest.

7900 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
7901 * lib/autotest/general.m4 (AT_INIT): Likewise.
7902 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7903 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
7904 AS_SHELL_SANITIZE.
7906 Use this M4sh to generate Autoconf's shell scripts.
7908 * tests/wrapsh.as: New, precursor of wrapsh.in.
7909 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
7910 on Autotest and M4sh.
7911 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
7912 (wrapsh.in): New target.
7913 * bin/autoconf.as: New, precursor of autoconf.in.
7914 (autoconf.in): New target.
7916 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
7918 * doc/autoconf.texi (Limitations of Make): Mention the issue
7919 with indented comments in rules.
7921 2002-04-09 Andreas Schwab <schwab@suse.de>
7923 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
7924 ac_top_builddir when setting ac_abs_top_builddir.

7928 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
7929 (Portable Shell): Cross reference to Systemology.
7931 2002-04-05 Akim Demaille <akim@epita.fr>
7933 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
7934 directories when descending in a SUBDIRS.
7935 Reported by Ezra Peisach.
7937 2002-04-04 Andreas Schwab <schwab@suse.de>
7939 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
7940 contains no literal separators.
7942 2002-04-03 Akim Demaille <akim@epita.fr>
7944 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
7945 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
7946 Use dnl, not the KILL diversion.
7947 Extracted from...
7948 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
7949 (AC_CONFIG_LINKS): here.
7950 Adjust.
7951 Don't use the KILL diversion, as it kills spurious output, which
7952 results in failures being hidden.
7953 Use m4_defn where appropriate.
7954 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
7955 after the second argument.
7956 Use m4_defn.
7957 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
7958 syntax, as it is provided by M4sugar.
7959 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
7961 2002-04-03 Andreas Schwab <schwab@suse.de>
7963 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
7964 expanded if $# <= 2.
7966 * bin/autoreconf.in (autoreconf): Run automake after rerunning
7967 aclocal.
7969 2002-04-03 Akim Demaille <akim@epita.fr>
7971 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
7972 (_AC_COMPILER_EXEEXT_REJECT): New.
7973 Also recognize *.bb and *.bbg as compilation byproducts.
7974 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
7975 (_AC_COMPILER_OBJEXT): Use them.
7976 Fixes Debian #138666.
7978 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
7980 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
7982 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
7983 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
7984 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
7985 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
7986 (AC_C_CONST): Same.
7987 (AC_C_INLINE): Same.
7988 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
7989 * doc/autoconf.texi, NEWS: Document.
7990 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
7991 AC_C_CROSS.
7993 2002-04-02 Akim Demaille <akim@epita.fr>
7995 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
7996 _AS_MKDIR_P_PREPARE.
7998 2002-03-28 Kevin Ryde <user42@zip.com.au>
8000 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
8001 to avoid versions of HP C which don't allow that.
8003 2002-03-27 Paul Eggert <eggert@twinsun.com>
8005 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
8006 (AS_SHELL_SANITIZE): Invoke it.
8007 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
8009 2002-03-26 Akim Demaille <akim@epita.fr>
8011 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
8013 2002-03-26 Akim Demaille <akim@epita.fr>
8015 * doc/autoconf.texi (Introduction): The GNATS base moved.
8017 2002-03-25 Paul Eggert <eggert@twinsun.com>
8019 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
8020 as POSIX requires, as it doesn't work with Zsh.
8021 * doc/autoconf.texi (Assignments): Document the problem.
8023 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8025 * doc/autoconf.texi (Limitations of Make): Mention more issue
8026 about VPATH, overriding of macros in sub-makes, and handling of
8027 SHELL.
8029 2002-03-21 Paul Eggert <eggert@twinsun.com>
8031 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
8032 problem with here-document buffer boundaries.
8034 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
8035 when reinvoking the shell, to work around problems with installers
8036 who put strange things like "cd" commands in their environments.
8038 2002-03-19 Akim Demaille <akim@epita.fr>
8040 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
8041 From Aaron Ucko.
8043 2002-03-19 Akim Demaille <akim@epita.fr>
8045 * bin/autoscan.in (scan_file): Specify the location in `&used'
8046 invocations.
8047 From Nicolas Joly.
8049 2002-03-19 Akim Demaille <akim@epita.fr>
8051 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
8052 From Nishio Futoshi.
8054 2002-03-19 Akim Demaille <akim@epita.fr>
8056 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
8058 2002-03-18 Paul Eggert <eggert@twinsun.com>
8060 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
8061 (Limitations of Usual Tools): Add mkdir section.
8063 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8064 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8065 back on AS_DIRNAME to compute prefixes otherwise; this is
8066 roughly what mkinstalldirs does. That way, we need not have
8067 our own filename disassembler. The old disassembler did not
8068 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8070 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8071 Create at_test_all by a series of assignments,
8072 not by a single assignment of a long string. The latter causes ksh
8073 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8074 presumably because of a buffer overrun.
8076 2002-03-14 Paul Eggert <eggert@twinsun.com>
8078 * lib/autotest/general.m4 (at_times_skip):
8079 Renamed from at_times. Now a boolean.
8080 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8081 says 'times: not found'.
8083 2002-03-14 Akim Demaille <akim@epita.fr>
8085 * bin/autoreconf.in (&study_gettextize): New.
8086 (&autoreconf): Handle newest gettextize.
8087 Rerun aclocal if needed.
8088 Suggested by Andreas Schwab.
8090 2002-03-13 Akim Demaille <akim@epita.fr>
8092 * doc/autoconf.texi (Special Shell Variables): More about IFS.
8094 2002-03-13 Akim Demaille <akim@epita.fr>
8096 * doc/autoconf.texi (Header Portability): New.
8097 Add information about stdint.h and inttypes.h from Paul Eggert.
8099 2002-03-13 Akim Demaille <akim@epita.fr>
8101 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
8102 -p'.
8103 From Bob Proulx.
8105 2002-03-12 Akim Demaille <akim@epita.fr>
8107 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
8108 m4_require.
8110 2002-03-11 Andreas Schwab <schwab@suse.de>
8112 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
8113 does not do it if --with-lispdir is given.
8115 2002-03-08 Akim Demaille <akim@epita.fr>
8117 Version 2.53.
8119 2002-03-08 Akim Demaille <akim@epita.fr>
8121 * doc/autoconf.texi (Subdirectories): Clarify that the
8122 subdirectory should exist.
8124 2002-03-08 Akim Demaille <akim@epita.fr>
8126 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
8128 2002-03-08 Akim Demaille <akim@epita.fr>
8130 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
8131 aliases the actual variables, and modifications of the former
8132 affect the latter.
8134 2002-03-08 Akim Demaille <akim@epita.fr>
8136 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
8137 because of C-c: have m4 output in tmp files, then mv them.
8139 2002-03-08 Akim Demaille <akim@epita.fr>
8141 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
8142 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
8143 * bin/ifnames.in: Copyright update.
8145 2002-03-08 Akim Demaille <akim@epita.fr>
8147 * doc/autoconf.texi (Invoking autom4te): New.
8149 2002-03-05 Akim Demaille <akim@epita.fr>
8151 * doc/autoconf.texi (Specifying Names): Clarification suggested by
8152 Kevin Ryde.
8154 2002-03-05 Akim Demaille <akim@epita.fr>
8156 Version 2.52i.
8158 2002-03-04 Akim Demaille <akim@epita.fr>
8160 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
8161 * lib/autoconf/general.m4 (AC_INIT): More informative error
8162 message for LIBOBJ.
8164 2002-03-04 Akim Demaille <akim@epita.fr>
8166 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
8167 parallel builds.
8169 2002-03-04 Akim Demaille <akim@epita.fr>
8171 * doc/autoconf.texi (Transforming Names): Equality between target
8172 and host is irrelevant.
8173 (Specifying Names, Canonicalizing): Remove all references to the
8174 backward compatibility hooks. Rather, collect them all into...
8175 (Hosts and Cross-Compilation): this new section.
8176 * doc/install.texi (System Type): Ditto.
8177 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
8178 that `--host' implies cross-compilation.
8180 2002-03-04 Akim Demaille <akim@epita.fr>
8182 * doc/autoconf.texi (Evaluation Macros): New.
8183 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8184 useless.
8185 (_m4_foreach): Define the variant with immediate evaluation so
8186 that it contains exactly the items, not an expression which
8187 evaluation is the current item.
8188 (m4_re_string, m4_re_word): Don't over quote them.
8190 2002-03-04 Akim Demaille <akim@epita.fr>
8192 Instead of having stacking `shift's evaluated at the end, let
8193 `foreach' loops immediately evaluate them.
8195 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8196 $*. This is the n-th time I change my mind, but hopefully this is
8197 the last...
8198 (m4_lquote): New.
8199 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8200 efficient.
8201 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8202 it was only a hack for m4_text_wrap.
8203 (m4_car2): Remove, replaced by...
8204 (m4_cdr): New.
8205 (_m4_foreach): Adjust.
8206 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8207 m4_bpatsubst for clarification.
8209 2002-03-04 Akim Demaille <akim@epita.fr>
8211 * doc/autoconf.texi (Changequote is Evil): New.
8213 2002-03-03 Kevin Ryde <user42@zip.com.au>
8215 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
8216 on old systems like SunOS.
8218 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
8220 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8221 lib/autoconf/functions.m4, lib/autoconf/general.m4,

8224 of messages.
8226 2002-02-28 Akim Demaille <akim@epita.fr>
8228 * lib/autotest/general.m4 (AT_INIT): Suggest a title to the
8229 message to be sent.
8231 2002-02-28 Kevin Ryde <user42@zip.com.au>
8233 * doc/autoconf.texi (Function Portability): Add va_copy and va_list.
8235 2002-02-25 Akim Demaille <akim@epita.fr>
8237 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
8238 From Akinori Musha.
8240 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
8242 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
8243 translate \r\n to \n.
8245 2002-02-07 Akim Demaille <akim@epita.fr>
8247 Version 2.52h.
8249 2002-02-07 Akim Demaille <akim@epita.fr>
8251 Fix Autoconf PR/209.
8252 Also reported by Frank Denis.
8254 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
8256 2002-02-07 Akim Demaille <akim@epita.fr>
8258 Fix Autoconf PR/207:
8259 AC_PREFIX_PROGRAM fails with dashed program names
8261 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
8262 variable when looking for the prefix program.
8263 Now it also works for shell variables.
8265 2002-02-07 Akim Demaille <akim@epita.fr>
8267 * doc/autoconf.texi (Limitations of Builtins): More about
8268 case/esac.
8270 2002-02-06 Akim Demaille <akim@epita.fr>
8272 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
8273 case/esac, some shells don't support it.
8274 Reported by Zack Weinberg.
8275 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
8277 2002-02-06 Akim Demaille <akim@epita.fr>
8279 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
8280 sure not to introduce newlines in at_groups.
8281 * lib/autotest/Makefile.am (autotest.m4f): Typo.
8283 2002-02-06 Akim Demaille <akim@epita.fr>
8285 * tests/torture.at (Configuring subdirectories): Skip if aclocal
8286 is not available.
8288 2002-02-05 Paul Eggert <eggert@twinsun.com>
8290 * doc/autoconf.texi (Specific Compiler Characteristics):
8291 Describe HP-UX cc bug workaround more accurately.
8292 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
8293 not unsigned long.
8294 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
8295 cross-compilers, too. This undoes some of the most recent change
8296 to this file.
8298 2002-02-05 Akim Demaille <akim@epita.fr>
8300 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
8301 to make sure they are up to date when `check' is run.
8303 2002-02-05 Akim Demaille <akim@epita.fr>
8305 * doc/autoconf.texi (Making testsuite Scripts): Document
8306 package.m4.
8308 2002-02-05 Akim Demaille <akim@epita.fr>
8310 * lib/freeze.mk: New.
8312 2002-02-05 Akim Demaille <akim@epita.fr>
8314 Implement `autom4te --freeze'.
8316 * bin/autom4te.in (&freeze): New.
8317 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
8318 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
8320 2002-02-05 Akim Demaille <akim@epita.fr>
8322 * bin/autom4te.in (&parse_args): Implement `frozen files are
8323 optional are the sum of the previous files on the command line'.
8324 Also, pass `--reload-state=' on them, so...
8325 (handle_m4): don't.
8326 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
8327 (M4sh): Rely on M4sugar.
8328 (Autotest, M4sh, M4sugar): Use frozen files.
8330 2002-01-31 Akim Demaille <akim@epita.fr>
8332 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
8333 * doc/autoconf.texi (Initializing configure): Adjust.
8335 2002-01-30 Akim Demaille <akim@epita.fr>
8337 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
8338 alphanumeric to `-' instead of `_'.
8340 2002-01-30 Akim Demaille <akim@epita.fr>
8342 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
8343 for plain code, the other for cross-compilation code. The latter
8344 is now run with GCC only.
8345 * doc/autoconf.texi (Compilers and Preprocessors): New.
8347 2002-01-30 Akim Demaille <akim@epita.fr>
8349 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
8350 values.
8351 * doc/autoconf.texi (Initializing configure): Explain how to
8352 change AC_INIT default values.
8354 2002-01-29 Akim Demaille <akim@epita.fr>
8356 * tests/torture.at (Configuring subdirectories): Use configure.in,
8357 so that aclocal 1.4 works.
8358 Reported by Alexandre Duret-Lutz and Larry Schmitt.
8360 2002-01-28 Akim Demaille <akim@epita.fr>
8362 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
8363 needs an argument.
8365 2002-01-28 Akim Demaille <akim@epita.fr>
8367 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8368 AUTOTEST_PATH *after* it was set.
8369 Don't put `.' in the PATH: the user should be precise and `./' if
8370 needed. In addition, given that the test suite does some `cd', if
8371 `.' is in the path, the `tested programs' sections will report
8372 programs found in the test suite's directory, while during the
8373 tests (performed in their own directory), these programs are no
8374 longer visible. In other words, the results is confusing and
8375 useless.
8376 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
8378 2002-01-24 Akim Demaille <akim@epita.fr>
8380 Version 2.52g.
8382 2002-01-24 Akim Demaille <akim@epita.fr>
8384 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
8385 * doc/autoconf.texi: Finally add Akim as an author.
8387 2002-01-24 Akim Demaille <akim@epita.fr>
8389 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
8390 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
8391 Bourne. Use /bin/sh.
8392 From Andreas Buening.
8394 2002-01-24 Akim Demaille <akim@epita.fr>
8396 * config/config.guess, config/config.sub, config/texinfo.tex:
8397 Update from masters.

8404 * config/missing.m4, config/sanity.m4, config/select.m4,
8405 * config/strip.m4: Remove, to ease sync'ing with any version of
8406 Automake.

8410 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
8411 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
8412 Reported by Geir Ove Myhr.
8414 2002-01-21 Akim Demaille <akim@epita.fr>
8416 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
8418 2002-01-21 Akim Demaille <akim@epita.fr>
8420 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
8421 message on invalid options.
8422 * bin/autom4te.in (parse_args): Don't use
8423 Autoconf::General::getopt with non valid options.
8425 2002-01-17 Jim Meyering <meyering@lucent.com>

8439 2002-01-06 Akim Demaille <akim@epita.fr>
8441 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
8442 package.m4, since is really depends upon configure.ac, not
8443 configure.
8444 * doc/autoconf.texi (testsuite Scripts): Adjust.
8445 * tests/Makefile.am (package.m4): New.
8446 EXTRA_DIST it since its a source.
8448 2002-01-06 Akim Demaille <akim@epita.fr>
8450 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
8451 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8452 and PACKAGE_BUGREPORT from here...
8453 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
8454 arguments.
8455 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
8456 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.

8459 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
8461 2002-01-06 Akim Demaille <akim@epita.fr>

8465 2002-01-03 Akim Demaille <akim@epita.fr>
8467 * doc/autoconf.texi (Output): Improved wording regarding use of
8468 AC_OUTPUT.
8469 From Olly Betts.
8471 2001-12-18 Kevin Ryde <user42@zip.com.au>
8473 * doc/autoconf.texi (Function Portability): Add notes on sscanf
8474 sometimes needing writable input.
8476 2001-12-17 Jim Meyering <meyering@lucent.com>
8478 * doc/autoconf.texi (New Macros): Tweak wording.
8480 2001-12-14 Akim Demaille <akim@epita.fr>
8482 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8483 trailing files, don't apply `-rf' to files which might not be
8484 created by configure (core, core.*, and *.core), but just `rm -f'.
8485 Suggested by Jonathan Kamens.
8487 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8489 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
8491 2001-12-14 Akim Demaille <akim@epita.fr>
8493 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8495 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
8497 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
8498 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
8499 abs_srcdir, top_srcpath to abs_top_srcdir.
8500 (_AC_OUTPUT_FILES): Adjust.
8501 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
8502 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
8503 * tests/wrappl.in, tests/wrapsh.in: Adjust.
8505 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
8507 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
8508 C/Fortran linking on HP/UX, by extracting the Fortran library
8509 search path from the LPATH line in the $F77 -v output.
8511 2001-12-12 Kevin Ryde <user42@zip.com.au>
8513 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
8514 forbidden file descriptors table.
8516 2001-11-26 Akim Demaille <akim@epita.fr>
8518 * bin/autoscan.in (%c_keywords): Build it at top level.
8519 Map to 1 in order to simplify its uses.
8521 2001-11-26 Akim Demaille <akim@epita.fr>
8523 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
8524 Remove $filepath, useless.
8525 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8526 variables, they are really part of the tokens.
8527 Split the input line on spaces and then look for tokens.
8528 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8529 because of `lex$U.$(OBJEXT)'.
8530 (&scan_files): Use "@list" instead of join.
8531 * doc/Makefile.am (CLEANFILES): Add *.fns.
8533 2001-11-26 Akim Demaille <akim@epita.fr>
8535 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
8536 Remove, replaced by...
8537 * tests/wrappl.in: Be common for all the Perl executables.
8538 In particular autoscan and autoheader want -I.
8539 * configure.ac: Adjust.
8540 * lib/autoscan/headers: errno.h is portable.
8542 2001-11-26 Akim Demaille <akim@epita.fr>
8544 * bin/autoscan.in (used): New.
8545 Use it.
8547 2001-11-26 Akim Demaille <akim@epita.fr>
8549 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
8550 directives.
8551 (&scan_sh_file): Remove a duplicate pattern.
8552 (&check_configure_ac): Use long options.
8553 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
8555 2001-11-26 Akim Demaille <akim@epita.fr>
8557 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
8558 Before, having a line containing the opening of a multi line
8559 comment made the whole line be ignored.
8561 2001-11-26 Akim Demaille <akim@epita.fr>
8563 * doc/autoconf.texi (Using an Autotest Test Suite): New.
8564 (testsuite Scripts): Be one of its subsection.
8565 (Autotest Logs): New.
8567 2001-11-26 Akim Demaille <akim@epita.fr>
8569 Test groups are now run two directories deeper.
8571 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
8572 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
8573 at_top_builddir.
8574 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
8575 top_srcdir, builddir and top_builddir.
8576 Use `at_*dir' relatively to the directory containing the
8577 suite, use `*dir' when relatively to the current group dir.
8579 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
8581 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
8582 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
8583 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
8584 spelling errors.
8586 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8588 * doc/autoconf.texi (Using System Type): Add an example of `case
8589 $host' usage so people quit using `case $target' everywhere.
8591 2001-11-22 Akim Demaille <akim@epita.fr>
8593 * doc/autoconf.texi (Installation Directory Variables): Englishoes
8594 spotted by Jim Meyering.
8596 2001-11-16 Paul Eggert <eggert@twinsun.com>
8598 This patch implements a `long double' suggestion by Oliver Kiddle.
8600 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8601 static, to catch errors if the value isn't known at compile-time
8602 and the compiler supports dynamic arrays. Change its name from
8603 `_array_' to `test_array' to avoid potential name clashes.
8604 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8605 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8606 better than double. Catch a bug in GCC 2.95.2 x86.
8607 * doc/autoconf.texi (C Compiler): Document the above.
8608 * NEWS: Likewise.
8610 2001-11-13 Akim Demaille <akim@epita.fr>
8612 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8613 hand.
8614 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8616 2001-11-13 Akim Demaille <akim@epita.fr>
8618 * lib/autotest/general.m4 (AT_INIT): After having run the test
8619 group, go back to the initial directory, not to at_suite_dir.
8621 2001-11-13 Akim Demaille <akim@epita.fr>
8623 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8624 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8625 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8626 option.
8627 (AT_CHECK_CONFIGURE): Use absolute paths.
8628 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8629 The problem is still the old one: there is no means in M4 (that I
8630 know about) to create a defining macro, because there is no means
8631 to create `$1' etc., therefore, the defining macro ``swallows''
8632 all the arguments meant to the defined macro.
8634 2001-11-13 Akim Demaille <akim@epita.fr>
8636 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8637 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8638 configure.ac.
8639 * tests/aclocal.m4: Remove, as it is no longer used.
8641 2001-11-13 Akim Demaille <akim@epita.fr>
8643 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8644 variable names when referring to a single test group, or to
8645 `suite' when referring to the whole test suite.
8646 `at_last_test' is removed: m4 compute at_format itself.
8647 (at_stdout, at_stder1, at_stderr): New variables.
8648 (AT_CHECK): Use them.
8650 2001-11-13 Akim Demaille <akim@epita.fr>
8652 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8653 in PATH.
8654 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8655 Do it as soon as a test fails, don't wait till the end of the test
8656 suite.
8657 Don't remove $as_me.[0-9]*, since these files no longer exist.
8659 2001-11-13 Akim Demaille <akim@epita.fr>
8661 * tests/tools.at: Use absolute paths, since we are no longer run
8662 in place.
8664 2001-11-13 Akim Demaille <akim@epita.fr>
8666 Now that tests are running in their own private dir, there is no
8667 need to list the files to remove at the end of tests groups.
8669 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8670 (AT_data_files, at_data_files): Remove.
8671 (AT_CLEANUP, AT_DATA): Simplify.
8672 (AT_INIT): Adjust.
8673 Remove the group dir if !debug && !failed.
8674 * tests/atspecific.m4: Adjust.
8676 2001-11-13 Akim Demaille <akim@epita.fr>
8678 Start a new layout for Autotest: `testsuite' creates
8679 `testsuite.dir' in which the at-check-line etc. files are to be
8680 found, and `testsuite.dir/003' where the test group 3 is run.
8682 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8683 at_check_line_file, at_format, at_test_normalized, at_group_dir
8684 are new variables.
8685 Create the directories.
8686 Use absolute paths for at- files.
8687 (AT_CHECK): Adjust.
8689 2001-11-11 Michael Matz <matz@kde.org>
8691 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8692 (m4_car2): New.
8693 (m4_car): Properly quote arguments.
8695 2001-11-13 Akim Demaille <akim@epita.fr>
8697 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8698 with stricter rules on LIBOBJS.
8700 2001-11-12 Paul Eggert <eggert@twinsun.com>
8702 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8703 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8704 __PROTOTYPES too.
8706 2001-11-12 Akim Demaille <akim@epita.fr>
8708 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8710 2001-11-12 Akim Demaille <akim@epita.fr>
8712 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8713 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8714 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8715 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8716 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8717 specify to what the macro should be defined (typically to 1).
8719 2001-11-12 Akim Demaille <akim@epita.fr>
8721 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8722 From Jim Meyering.
8724 2001-11-12 Akim Demaille <akim@epita.fr>
8726 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8727 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8728 definition used by Automake where LEX is +/- "${missing} lex" and
8729 `missing' itself contains variables.
8731 2001-11-12 Akim Demaille <akim@epita.fr>
8733 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8734 Now that M4sh pushes BODY, the comments were output at the end of
8735 the test suites.
8737 2001-11-08 Akim Demaille <akim@epita.fr>
8739 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8740 that we can trace macros from aclocal.m4.
8741 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8742 obsoleted, and redirect to the former anyway.
8743 Reported by Ralf Corsepius.
8745 2001-11-08 Akim Demaille <akim@epita.fr>
8747 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
8748 processed only if present.
8749 * tests/torture.at (Configuring subdirectories): Use autoreconf
8750 instead of successive calls to autoconf.
8751 Add a nonexistent subdirectory to exercise the patch above.
8752 Reported by Ralf Corsepius.
8754 2001-11-08 Kevin Ryde <user42@zip.com.au>
8756 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
8757 doesn't accept .S files.
8759 2001-11-07 Akim Demaille <akim@epita.fr>
8761 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
8762 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
8763 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
8764 * bin/autom4te.in (warn_forbidden): New.
8765 (handle_output): Use it.
8766 Read m4_pattern_forbid with messages.
8768 2001-11-05 Akim Demaille <akim@epita.fr>
8770 * bin/autom4te.in (--normalize): Remove.
8771 * lib/autom4te.in: Adjust.
8773 2001-11-05 Akim Demaille <akim@epita.fr>
8775 * tests/Makefile.am (testsuite): Rename this target as...
8776 ($(TESTSUITE)): this.
8777 From Nicolas Joly.
8779 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
8781 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
8782 the --prefix option, also remove it's argument.
8784 2001-11-05 Akim Demaille <akim@epita.fr>
8786 * doc/autoconf.texi (testsuite Invocation): Update.
8787 (Writing testsuite.at): Update.
8789 2001-11-03 Akim Demaille <akim@epita.fr>
8791 * doc/autoconf.texi: s/@code/@command/ where appropriate.
8793 2001-11-03 Akim Demaille <akim@epita.fr>
8795 * lib/Autom4te/General.pm: (&catfile, &canonfile)
8796 (&file_name_is_absolute): New, wrappers around routines from
8797 File::Spec.
8798 Use and export them.
8799 (&find_configure_ac): Optionally take a directory where to look at.
8800 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
8801 the arguments.
8802 Default @ARGV to `.', not find_configure_ac.
8803 (&autoreconf): Argument is a directory.
8804 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
8805 * doc/autoconf.texi (autoreconf Invocation): Update.
8807 2001-11-03 Akim Demaille <akim@epita.fr>
8809 * lib/Autom4te/General.pm (@export_vars, @export_subs)
8810 (@export_forward_subs): New.
8811 Add basename, dirname, and fileparse.
8812 (@EXPORT): Adjust.
8813 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8814 Don't look for aclocal flags if we already know aclocal is not
8815 used.
8816 Move aclocal.m4t only if it exists.
8817 Reported by Ezra Peisach.
8819 2001-11-03 Akim Demaille <akim@epita.fr>
8821 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8822 passed on command line, defaulting to ./configure.ac if present.
8823 (&maybe_autoreconf, File::Find): Remove, unused.
8824 (&autoreconf): If autoconf is not used, don't try to trace.
8826 2001-11-02 Akim Demaille <akim@epita.fr>
8828 * configure.ac: Bump to 2.52g.
8830 2001-11-02 Akim Demaille <akim@epita.fr>
8832 Version 2.52f.
8834 2001-11-02 Akim Demaille <akim@epita.fr>
8836 * config/config.guess, config/config.sub, doc/standards.texi:
8837 * config/lispdir.m4: Update from masters.
8838 * configure.ac: Bump to 2.52f.
8840 2001-11-02 Akim Demaille <akim@epita.fr>
8842 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8843 Don't run aclocal when aclocal.m4 is not from aclocal.
8844 From Ezra Peisach.
8845 Don't run libtoolize and gettextize if --install is not given.
8847 2001-11-01 Paul Eggert <eggert@twinsun.com>
8849 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8850 be invoked before _AS_LINENO_PREPARE.
8851 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
8852 than character ranges.
8854 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
8855 invoking AS_BASENAME. Set the locale variables to 'C' if
8856 possible, as POSIX requires this to get the traditional
8857 behavior.
8858 * doc/autoconf.texi (Special Shell Variables): Describe the above.
8860 2001-10-31 Paul Eggert <eggert@twinsun.com>
8862 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
8863 with {}, as that triggers a bug in Bash 2.05.
8865 (_AS_LINENO_PREPARE): Use Sed rather than
8866 Awk. Fix the sed prepass to work even if there are multiple
8867 instances of $LINENO on the same line. Do not substitute for
8868 other variables like $LINENOT. Do not check file dates; such a
8869 check is unreliable on sufficiently fast machines, and removing
8870 the check makes the code simpler and more reliable. Check for
8871 output and chmod failures.
8873 * doc/autoconf.texi (Special Shell Variables): Document
8874 the above.
8876 2001-10-31 Akim Demaille <akim@epita.fr>
8878 * tests/Makefile.am (atconfig): Remove this target, Automake
8879 handles it now.
8881 2001-10-31 Akim Demaille <akim@epita.fr>
8883 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
8884 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
8885 provided, while it is optional.
8886 * configure.ac: Adjust.
8888 2001-10-26 Paul Eggert <eggert@twinsun.com>
8890 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
8891 lib/Autom4te/Struct.pm:
8892 Require Perl 5.005_03 instead of just 5.005, as some tests fail
8893 with 5.005_02.
8895 * doc/autoconf.texi (Special Shell Variables): Document some
8896 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
8898 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
8899 (_AS_LINENO_PREPARE): Use it instead of shell eval, since

8919 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
8920 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
8921 POSIX decided to standardize on the int flavor of strerror_r.
8922 Always do char* test, as there's no reason not to.
8923 Assign to a char* var, to catch strerror_r that returns int*.
8925 * doc/autoconf.texi (Particular Functions):
8926 Document the above changes. Also, document the fact that

8956 options.

9267 * tests/fortran.at (GNU Fortran 77): there.
9268 * doc/autoconf.texi (autoconf Invocation): Fix the example:
9269 AC_TRY_RUN is about compilation, not shell commands.

9373 * lib/autoconf/autotest.m4: Create `package.m4'.
9374 * tests/Makefile.am (package.m4): Remove.
9376 2001-09-22 Akim Demaille <akim@epita.fr>
9378 Rely on `$LINENO' when possible instead of `__oline__'.
9380 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
9381 `$LINENO' support replacement when not supported.
9382 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
9383 them explicitly to be sure they are not output before this section
9384 (via m4_require). Cosmetic only.
9385 * lib/autoconf/c.m4, lib/autoconf/general.m4,
9386 * lib/autoconf/programs.m4: Replace all the occurrences of
9387 `__oline__' with `$LINENO'.
9388 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
9390 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
9392 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
9393 character (u: -> ue) in a code comment.
9394 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
9395 it works.
9397 2001-09-21 Akim Demaille <akim@epita.fr>
9399 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
9400 Suggested by Jim Meyering.
9402 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9404 * lib/autoconf/programs.m4: Use extensions listed in

9411 setting up ac_dir_suffix and ac_top_builddir.
9412 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
9414 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9416 * doc/autoconf.texi (File System Conventions): Clarify the use of
9417 PATH_SEPARATOR.
9418 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
9419 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
9420 be used instead of ':'.
9421 * lib/autotest/general.m4: Replace occurrences of ':' in
9422 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
9424 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9426 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
9427 arguments. Fixed a typo.
9429 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9431 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
9432 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
9434 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9436 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

9443 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9445 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
9446 already have $file). Set output files to binary mode (helps avoid
9447 CR issues on DOSish systems).
9449 2001-09-19 Akim Demaille <akim@epita.fr>
9451 * lib/autotest/general.m4: Englishoes.
9452 From Tim Van Holder and Alexey Mahotkin.
9454 2001-09-18 Paul Eggert <eggert@twinsun.com>
9456 * doc/autoconf.texi (Common Shell Constructs): New node,
9457 documenting AS_DIRNAME.
9458 (Limitations of Usual Tools): Refer to it when discussing dirname.
9459 Also, update discussion of POSIX standard to reflect latest draft.
9461 * lib/autoconf/c.m4:
9462 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9464 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9465 Do not pass a first argument with leading '-'
9466 to expr, by parenthesizing initial integers that might be negative.
9468 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9469 now merely checks whether it is an error to pass an argument
9470 to getpgrp.
9472 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9473 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9474 whether it is a (compile-time) error to pass an argument to
9475 getpgrp. This simpler test supports the revised documentation,
9476 and is all that AC_FUNC_GETPGRP's users really need.
9478 2001-09-18 Akim Demaille <akim@epita.fr>
9480 * doc/autoconf.texi (Limitations of Make) <$<>: New.
9482 2001-09-18 Akim Demaille <akim@epita.fr>

9488 2001-09-18 Paul Wagland <paul@wagland.net>
9490 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
9491 correctly.
9492 Add test for AS_BASENAME.
9493 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9494 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9495 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9496 * tests/base.at: Fixed the expected responses. The old ones were
9497 one line out...
9498 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9499 the documentation claims it should (and how it behaved in 2.13).
9501 2001-09-18 Akim Demaille <akim@epita.fr>
9503 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9504 the AC_CONFIG_COMMANDS invocation.
9505 This also solves the name clash problems.
9506 Don't set the package's ID.
9507 * lib/m4sugar/Makefile.am (version.m4): Revamp.
9508 No longer to be shipped.
9509 (version.in): Remove.
9510 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
9511 * lib/autoconf/status.m4: Adjust.
9512 Use `m4_PACKAGE_STRING'.
9513 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9514 the only optional argument is the name of the test suite.
9515 Expect `package.m4' to define the package signature.
9516 * lib/autom4te.in (Autotest): Add `package.m4?'.
9517 * tests/Makefile.am (package.m4): New.
9518 * tests/suite.at: ifnames is a victim.
9520 2001-09-18 Akim Demaille <akim@epita.fr>
9522 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
9523 AC_LIBSOURCE, AC_CONFIG_FILES.
9524 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
9525 program version string doesn't match the package's.
9526 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
9527 after `(cached)'.
9529 2001-09-17 Paul Eggert <eggert@twinsun.com>
9531 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9532 Allow expression to return any value that can fit into unsigned long
9533 (not int, as before). Check for output errors.
9535 2001-09-17 Bruno Haible <haible@ilog.fr>
9537 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9538 Always include <stdio.h> and <stdlib.h>. Evaluate
9539 the expression in an extra function before these includes. Call
9540 fprintf "%d" only after ensuring the argument is of type 'int'.
9541 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
9543 2001-09-17 Paul Eggert <eggert@twinsun.com>
9545 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9546 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9547 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9548 when they don't exist.
9550 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
9551 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
9552 need it.
9554 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
9555 version with the version used by fileutils 4.1, except use
9556 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
9557 we don't need it.
9559 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
9561 2001-09-13 Akim Demaille <akim@epita.fr>
9563 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
9564 _first_.
9565 Reported by Gerrit P. Haase.

9569 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

9586 Likewise.
9587 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
9588 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
9589 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
9590 AT_tests_all for consistency.

9593 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
9595 2001-09-13 Akim Demaille <akim@epita.fr>
9597 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
9599 2001-09-13 Akim Demaille <akim@epita.fr>
9601 * lib/autotest/general.m4 (AT_INIT): Create and remove
9602 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
9603 test suites can cohabit.
9605 2001-09-13 Akim Demaille <akim@epita.fr>
9607 * tests/mktests.sh: Don't output banners for empty test files.
9609 2001-09-13 Akim Demaille <akim@epita.fr>
9611 Test suites can be run independently of configure.

9657 2001-09-10 Akim Demaille <akim@epita.fr>
9659 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass
9660 PATH_SEPARATOR, let M4sh compute it.

9662 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

9675 2001-09-07 Akim Demaille <akim@epita.fr>

9679 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
9680 related variables into `at_package_*'.

9707 From Uwe Seimet.

9713 2001-09-05 Akim Demaille <akim@epita.fr>
9715 Be ready to handle filenames as stupid as `dnl.at', for if even
9716 the maintainer is dumb enough to do that...
9718 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
9719 excellence in M4 quotation: consider `__file__' is active.
9721 And BTW, when invoking m4, pass the --include in the right order:
9722 the wrong one.
9724 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

9747 2001-09-05 Akim Demaille <akim@epita.fr>

9752 New, extracted from main.
9753 Use IO::File wherever possible.
9754 (input.m4): Be constant, use -I instead of hard coding $tmp.
9755 Therefore be a quoted heredoc.
9756 Don't invoke `_au_disable', since ac was not loaded, but just

9759 2001-08-31 Akim Demaille <akim@epita.fr>
9761 Version 2.52d.

9786 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
9787 (testsuite Scripts): There is no such thing as `atconfig.in'.
9788 And actually one diagram is missing: test suite runtime.
9790 2001-08-31 Akim Demaille <akim@epita.fr>
9792 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
9793 inverse order.
9795 2001-08-31 Akim Demaille <akim@epita.fr>
9797 * bin/autoupdate.in (@include): `installcheck' revealed the path
9798 to m4sugar was lacking!
9800 2001-08-31 Akim Demaille <akim@epita.fr>
9802 * man/Makefile.am (.x.1): We really have to pass
9803 autom4te_perllibdir.
9805 2001-08-31 Akim Demaille <akim@epita.fr>
9807 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
9808 debug scripts, in particular passing explicitly listed tests to
9809 run is stupid.
9811 2001-08-31 Akim Demaille <akim@epita.fr>
9813 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
9814 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
9815 Use directly autom4te, not autoconf.

9839 `print $out' doesn't print `$_' but `$out'.
9840 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
9841 (autoheader): Pass --force since the test suite goes too fast for
9842 the time stamps.
9843 Adjust to the new autoheader messages.
9845 2001-08-31 Akim Demaille <akim@epita.fr>
9847 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
9848 Check the completeness of the #template.
9849 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
9850 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
9851 invocation.
9853 2001-08-31 Akim Demaille <akim@epita.fr>
9855 * lib/Autom4te/General.pm (&find_file, &update_file): New.
9856 * bin/autoupdate.in, bin/autoheader.in: Adjust.
9857 Drop AC_MACRODIR dead for real.
9858 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
9859 `autoheader: `config.hin' is created'.
9860 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
9862 2001-08-31 Akim Demaille <akim@epita.fr>
9864 * bin/autoheader.in: Rewrite in Perl.
9865 * tests/autoheader: Adjust.
9867 2001-08-31 Akim Demaille <akim@epita.fr>
9869 * bin/autoconf.in (--include, -I): New option.
9870 Map --localdir, --autoconf-dir onto it.
9871 Forward autom4te's options instead of interpreting them.
9872 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
9873 There is no such envvar since the inception of autom4te.cfg.
9874 * bin/autom4te.in (&parse_args): Uniquify `@include'.
9875 * bin/autoupdate.in: Adjust, and perform more control.
9876 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
9877 * tests/autoconf: Dittowise.
9879 2001-08-31 Akim Demaille <akim@epita.fr>
9881 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
9882 * bin/autom4te.in (&find_file): Support `FILE?' standing for
9883 optionally `FILE'.
9884 Use -e, not -f, since /dev/null for instance is OK.
9885 (&parse_args): Adjust.
9886 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
9888 2001-08-31 Akim Demaille <akim@epita.fr>
9890 * configure.ac: Also find tested executables in bin.
9891 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
9892 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
9893 installed peer executables, only PATH is allowed to resolve it.
9894 Pass `autoconf_dir' via options, not via invisible envvars.
9895 * lib/Autom4te/General.pm (&find_peer): Remove.
9896 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
9897 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
9898 * man/Makefile.am: Let help2man rely on PATH instead of trying to
9899 find the executables for it.
9900 * tests/Makefile.am: Major cleanup. Too lazy to document...
9901 * tests/atlocal.in: Remove all the obscure envvar manipulations.
9902 We only need PERL.
9903 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
9904 indeed related to running the test suite, while passing
9905 --autoconf-dir and others is related to running non installed
9906 Autoconf executables. So don't do that, leave it to...
9907 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
9908 * tests/autoscan: New.
9909 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
9910 refer to library files: rely on --language.
9912 2001-08-29 Akim Demaille <akim@epita.fr>
9914 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
9915 s/--set/--language/.
9917 2001-08-29 Akim Demaille <akim@epita.fr>
9919 * doc/autoconf.texi: Strip the @nodes.
9920 Suggested by Paul Eggert.
9921 (Initializing configure): Typo.
9923 2001-08-29 Akim Demaille <akim@epita.fr>
9925 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
9926 Suggested by Paul Eggert.
9928 2001-08-29 Akim Demaille <akim@epita.fr>
9930 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
9931 download in a tmp dir.
9933 2001-08-29 Akim Demaille <akim@epita.fr>
9935 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
9936 case insensitive OSes out there :(

9955 foo=`(command) 2>/dev/null`
9956 not
9957 foo=`command` 2>/dev/null
9958 (at-devnull): Rename as...
9959 (AT-devnull): this.
9960 (--clean): Remove AT-* files too.

9962 Reported by Nicolas Joly.
9964 2001-08-28 Akim Demaille <akim@epita.fr>

9996 * lib/autotest/general.m4 (AT_INIT): Log the command line.
9997 Support `VAR=VAL' as arguments.
9998 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
9999 may be set via the command line.

10003 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.

10017 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
10018 `ac_top_builddir' to mimic Automake's vocabulary, which much more
10019 readable.
10020 Adjust callers.
10021 * doc/autoconf.texi (Configuration Actions): Document the vars
10022 available in commands.
10023 Emphasize the risks of collisions in init-cmds.

10027 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
10028 (Initializing configure): this new node.
10030 2001-08-27 Akim Demaille <akim@epita.fr>

10054 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
10055 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
10056 -> ac_dir).

10086 (AMTAR): Help automake define it.

10090 * m4/strip.m4: New.

10105 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
10106 the name of the directory they're in, instead of the filename,
10107 since version.m4 is now in m4sugar, but m4_acversion must not be
10108 classified as an Autoconf macro.
10109 ($input_m4): Don't qualify the path to m4sugar.
10110 Rather, pass autoconf_dir to m4.
10111 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

10131 Use the same log introduction as configure's.
10133 2001-08-22 Paul Eggert <eggert@twinsun.com>
10135 * doc/autoconf.texi (Indices): New node.
10136 Move indices out of the top level menu and into this submenu.
10138 2001-08-22 Akim Demaille <akim@epita.fr>
10140 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10141 AC_TRY_COMMAND.
10142 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.
10144 2001-08-22 Akim Demaille <akim@epita.fr>
10146 * lib/autoconf/general.m4 (AC_SHELL_PATH_WALK, AC_CHECK_PROG)

10191 AC_COMPILE_IFELSE. Cleanup grep usage.
10193 2001-08-20 Akim Demaille <akim@epita.fr>
10195 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
10196 * NEWS, README, README-alpha, TODO, tests/README: This package is
10197 `Autoconf', not `autoconf' (the executable).
10199 2001-08-20 Akim Demaille <akim@epita.fr>
10201 Info readers seem to need `Index' in the index node title :(
10203 * doc/autoconf.texi: Reverse the 2001-08-15 change which
10204 simplified index node names.
10206 2001-08-20 Akim Demaille <akim@epita.fr>
10208 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
10209 arguments are not literals.

10216 (Examining Syntax) <AC_TRY_COMPILE>

10222 2001-08-20 Akim Demaille <akim@epita.fr>

10248 2001-08-20 Akim Demaille <akim@epita.fr>
10250 Huh!?!?! There are still some user EOF tags used, which prevents
10251 their use in AC_CONFIG_COMMANDS for instance...
10253 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
10254 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
10255 `_CSEOF', or `_ATEOF', as appropriate.
10256 * lib/m4sugar/Makefile.am, lib/autoconf/Makefile.am,
10257 * lib/autotest/Makefile.am (check-local): Enforce this constraint.
10259 2001-08-20 Akim Demaille <akim@epita.fr>
10261 * tests/base.at, tests/m4sh.at, tests/m4sugar.at,

10267 Autotest invokes M4sh's initialization.

10317 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

10335 * doc/autoconf.texi: Work around Texinfo buglets.
10336 (Transformation Rules): One example is enough, users are expected
10337 to have their brains on. And BTW, use DESTDIR.
10338 (dvar): New macro. Use it.
10340 2001-08-17 Akim Demaille <akim@epita.fr>

10382 value.

10390 (cvs-dist): depends upon it.
10392 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
10394 * tests/Makefile.am: Use a clean-local rule to remove
10395 autom4te.cache (it's a directory, not a file.
10396 * Makefile.am: Ditto (but maintainer-clean-local).
10398 2001-08-15 Akim Demaille <akim@epita.fr>
10400 * bin/autom4te.in (@m4_warning): New.
10401 (&handle_m4): Use it.
10402 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
10403 warnings are issued at each run.
10404 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
10405 is in the src tree.
10407 2001-08-15 Akim Demaille <akim@epita.fr>
10409 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
10410 don't waste time running `autoupdate --version' works.
10411 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
10413 2001-08-13 Akim Demaille <akim@epita.fr>

10472 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10474 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
10475 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
10476 * doc/autoconf.texi (C Compiler Characteristics): Update
10477 documentation for AC_C_BIGENDIAN.
10479 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10481 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
10482 magic values from an object file when cross-compiling.
10483 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
10485 2001-08-10 Akim Demaille <akim@epita.fr>
10487 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10488 effects.
10489 Suggested by Russ Allbery.
10491 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10493 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10494 current $prefix to the sub-configures.
10496 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10498 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10499 extension (needed on BeOS). Reported by Guido van Rossum.
10501 2001-08-09 Akim Demaille <akim@epita.fr>
10503 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10505 2001-08-07 Akim Demaille <akim@epita.fr>
10507 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10508 removed.
10509 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10510 No need to remove the files before and after the each test, before
10511 each test and at the end of the suite is enough.
10512 Display only the children `times', not the shell's.
10513 If the test failed or was skipped, at-times is not available.
10515 2001-08-07 Akim Demaille <akim@epita.fr>
10517 Always produce testsuite.log, including when there are no
10518 failures. This helps getting information on skipped tests, and
10519 duration of the tests. Err, implement the latter btw.
10521 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10522 Dump information on the first run of each test.
10523 (AT_CLEANUP): Create `at-times' containing the duration of the
10524 test group.
10526 2001-08-07 Akim Demaille <akim@epita.fr>
10528 The use of `dumpstat' revealed that `len' was used although it
10529 should not. m4_text_wrap was using it, but in the Autoconf world
10530 where it is legal. Hence (i) test M4sh in its own world, not
10531 Autoconf's, and (ii), ahem, fix the bug :)
10533 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10534 does not like `' instead of [].
10535 (AT_INIT): Forbid `^_?AT_'.
10536 And don't output such tokens.
10537 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10538 `script.as', and `autom4te.cache'.
10539 Remove `empty' and `macro' which are no longer used.
10540 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10541 * tests/m4sugar.at: Use it.
10542 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
10544 2001-08-07 Akim Demaille <akim@epita.fr>
10546 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
10548 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
10550 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
10552 2001-08-04 Akim Demaille <akim@epita.fr>
10554 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
10555 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
10556 AC_TRY_LINK.
10557 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
10558 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
10559 (AC_F77_MAIN): Likewise.
10561 2001-08-04 Akim Demaille <akim@epita.fr>
10563 Don't rely on M4sugar outputting the patterns in files, since we
10564 might process the output _without_ running m4, hence without these
10565 files.
10567 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
10568 * bin/autom4te.in (@Request::includes): Remove, unused.
10569 (@Request::source): Rename as...
10570 (@Request::input): this.
10571 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
10572 (&handle_output): Fetch the patterns from the traces.
10573 `$forbidden' and `$allowed' are constant: use m//o.
10574 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
10575 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
10577 2001-08-04 Akim Demaille <akim@epita.fr>
10579 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
10580 autoconf', i.e., in addition to caching traces, cache the output.
10582 * bin/autom4te.in (Request::cache): Rename as...
10583 (Request::id): this.
10584 ($cache, $icache, $tcache, $ocache): New.
10585 (&handle_m4): Save M4 output in the cache instead of $tmp.
10586 (&handle_output): Adjust.
10587 (&up_to_date_p): Check that the output cache is up to date too.
10588 (top level): Run `&handle_m4' iff force or the cache is invalid.
10589 Run `&handle_output' if the output cache is more recent.
10591 2001-08-04 Akim Demaille <akim@epita.fr>
10593 * bin/autom4te.in ($force): New.
10594 (&parse_args, &print_usage): -f, --force is a new option.
10595 (&handle_output): CPP directives might have spaces after `#'.
10596 (&parse_args): The first file only can be frozen.
10598 2001-08-04 Akim Demaille <akim@epita.fr>
10600 Don't let autom4te compute the `include' traces several times:
10601 first check that the trace cache file is up to date, and then
10602 compare its timestamp with that of the output.
10604 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
10605 the preamble. Don't require 5.005 as Autom4te::General does it,
10606 and better yet (use `use', not `require'!).
10607 * lib/Autom4te/Struct.pm: Rename the last occurrences of
10608 Class::Struct as Autom4te::Struct.
10609 * lib/Autom4te/General.pm (File::stat): Use it.
10610 (&mtime): New, export it.
10611 * bin/autom4te.in: Use it.
10612 Declare `$req' is invalid if it is outdated.
10613 Don't declare it valid before saving it if something went wrong.
10615 2001-08-04 Akim Demaille <akim@epita.fr>
10617 Autom4te shall not encode Autoconf data, and preselecting traces
10618 must be proposed to the users.
10620 * bin/autom4te.in (@required_trace): Remove.
10621 (@preselect): New.
10622 (&parse_args, &print_usage): -p, --preselect is a new option.
10623 (&up_to_date_p): Adjust.
10624 * bin/autoconf.in: Preselect some Autoconf macros.
10626 2001-08-04 Akim Demaille <akim@epita.fr>
10628 * tests/tools.at (autoconf --trace: user macros): Check traces on
10629 macros invoked without arguments, and macros invoked with multiple
10630 lines arguments.
10632 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
10634 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
10635 arguments.
10637 2001-08-03 Akim Demaille <akim@epita.fr>
10639 * bin/autoconf.in ($@): Work around the usual sh bug.
10640 From Nicolas Joly.
10642 2001-08-03 Akim Demaille <akim@epita.fr>
10644 Clean up the handling of the M4 builtins tracing exception.
10646 * bin/autom4te.in (Request::request): Don't complete M4 builtins
10647 trace requests.

10649 (@m4_builtin): this.
10650 (%m4_builtin_alternate_name): New.
10651 (&parse_args): Complete the trace requests with alternate names.
10652 (&handle_traces): Hence no longer do it here.
10653 (&trace_requests): Remove, unused.
10655 2001-08-03 Akim Demaille <akim@epita.fr>
10657 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
10658 m4_if, and m4_wrap.
10660 2001-08-03 Akim Demaille <akim@epita.fr>
10662 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
10663 (m4_divert_pop): Dump the whole diversion stack when a diversion
10664 mismatch happens.
10665 * bin/autom4te.in (&handle_output): Remember of the first
10666 occurrence of a possibly undefined macro, not the last.
10667 Complain about the possibly undefined macros in the same order as
10668 the appear in the output.
10669 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
10670 * tests/tools.at (autoconf: forbidden tokens, basic)
10671 (autoconf: forbidden tokens, exceptions): No longer sort
10672 autoconf's stderr, as it is now deterministic.
10673 Check that `dnl' is caught.
10675 2001-08-01 Akim Demaille <akim@epita.fr>
10677 * configure.ac: Bump to 2.52c.

10692 `die'.
10693 (&END): New.
10694 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
10695 `END', as `Autom4te::General::END' will be triggered.
10696 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
10697 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

11089 compiler, not the preprocessor.
11090 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): No longer use

11096 2001-07-03 Akim Demaille <akim@epita.fr>

11125 * aclang.m4 (AC_F77_DUMMY_MAIN): New macro to detect whether a
11126 dummy alternate main is required even if the user provides her own
11127 'main'.
11128 (AC_F77_MAIN): New macro to detect whether it is possible to
11129 provide an alternate 'main' function name, using the 'main' from
11130 the Fortran libraries.
11131 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
11132 cross-language link tests can be performed successfully.
11133 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
11134 after $LIBS, for consistency; this should be the general rule since
11135 the user may want to link to Fortran libraries that require $FLIBS.
11136 * doc/autoconf.texi: Document AC_F77_DUMMY_MAIN and AC_F77_MAIN.
11138 2001-06-29 Pavel Roskin <proski@gnu.org>
11140 * atgeneral.m4 (AT_CHECK): Add a newline to the end of
11141 at-stdout and at-stderr instead of removing the newline
11142 from the echo output, which is not guaranteed to work.
11144 2001-06-28 Jens Petersen <petersen@redhat.com>
11146 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to

11180 (&output_kind): here.
11181 (File::Basename): Use it.

11203 2001-06-23 Akim Demaille <akim@epita.fr>
