1 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
3 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4 when using default mode of IBM C 6 for AIX. Problem and two-line
5 fix reported by Larry Jones.
7 2006-06-22 Alexandre Julliard <julliard@winehq.org>
9 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
10 about literal '${datarootdir}' if a definition is found in the
11 output file.
13 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
15 * NEWS: Use "M4" rather than "m4" when appropriate.
16 Problem reported by Eric Blake.
17 * doc/autoconf.texi: Likewise.
18 Use @acronym around BSD, GCC, and GNU when appropriate.
19 (Why GNU M4): Renamed from "Why GNU m4".
20 (Redefined M4 Macros): Mention that Posix
21 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
22 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
23 to int.
25 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
27 * bin/autom4te.in (handle_output): Do not forbid the empty
28 pattern.
29 * tests/tools.at (autoconf: the empty token): New test.
31 2006-06-20 Stepan Kasal <kasal@ucw.cz>
33 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
34 calls, so that we do not care whether they are LIFO or FIFO;
35 in the m4_wrap, do not check which diversion is the topmost
36 one, just check that the stack is balanced at the end.
37 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
38 base diversion forever--pop the previous diversion before
39 opening the new one; consequently, remove the m4_wrap call.
40 * lib/autotest/general.m4 (AT_INIT): Likewise.
41 * tests/m4sugar.at: Do not use
42 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
44 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
45 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
47 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
48 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
49 Rework example of m4wrap token-pasting trouble so that it doesn't
50 care whether it's LIFO or FIFO.
51 Fix some "contrary to"s that are awkward in English.
53 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
55 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
56 to `yes' instead of `int$1_t' if the type is found, for more
57 consistent configure output (where $1 is the number of bits).
58 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
59 Suggested by Bruno Haible.
61 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
62 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
63 with system headers. Report by Bruno Haible.
65 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
67 * config/config.guess, config/config.sub: Sync from upstream.
69 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
70 in order to avoid picking up an older installed frozen m4sh.m4f.
71 Besides an outdated shell startup, this could have been created
72 by an earlier M4 version with incompatible frozen file format.
74 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
76 * README: Recommend m4 1.4.4 instead of 1.4.3..
77 * doc/autoconf.texi: Likewise.
78 (Special Chars in Names): Say that $(.FOO) is portable, as
79 suggested by Stepan Kasal.
80 (Installation Directory Variables, Build Directories):
81 (Automatic Remaking, Subdirectories, Fortran Compiler):
82 (Making testsuite Scripts, Defining Directories):
83 Quote variable usages better.
84 (Making testsuite Scripts): Add clean-local rule to makefile
85 snippet, by Eric Blake.
86 (Installation Directory Variables): Fix table item font.
87 Reword slightly to clarify. Generalize advice about
88 not using special characters to include all file-related
89 vars, not just VPATH.
90 (Special Chars in Variables): Warn about special characters in
91 $(srcdir) too.
92 (Assignments): Clarify default-value example as suggested by
93 Ralf Wildenhues in
94 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
95 (Special Shell Variables): Note leading ./ or ../, as suggested
96 by Eric Blake.
97 (Limitations of Builtins): Under cd, warn about CDPATH.
98 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
99 Ralf Wildenhues.
101 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
103 * doc/autoconf.texi (Configuration Actions): Remove duplicate
104 `@var', for texi2html.
105 (Systemology): Some more word wrapping, for DVI output.
106 (autom4te Invocation): The short option for `--melt' is `-M',
107 not `-m'.
109 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
111 * doc/autoconf.texi: More formatting and English tweaks,
112 many suggested by Ralf Wildenhues.
113 Reword to avoid "@code{...}'s" and the like, since it's ugly
114 with Emacs info mode. discontents -> woes.
115 Put a few "will"s back. time stamp -> timestamp.
116 side-effect -> side effect.
118 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
120 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
121 Warn about $@ not persisting. Problem reported by Julien Danjou in
122 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
123 (Special Chars in Names): Renamed from Leading _ in Macro Names.
124 Mention other special chars, too.
126 2006-06-14 Eric Blake <ebb9@byu.net>
128 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
130 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
132 * doc/autoconf.texi: Some systematic minor improvements, as
133 follows. Use "makefile" when talking about makefiles
134 generally (which might be named "makefile" or "Makefile" or even
135 "foo.mk"), "Makefile" when talking about a specific makefile
136 called "Makefile". This unclutters the text from weird quotes
137 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
138 values" rather than "@var{foo}s" and similar constructs containing
139 "}s". Use "Make rules" rather than "Makefile rules". Minor
140 English-language improvements. Change the prefix "sub-" to "sub"
141 and "re-" to "re".
142 Put blank lines around examples more consistently.
143 Avoid "rather" and "very" as intensifiers.
144 Avoid "will" as an auxiliary.
145 (Limitations of Make): Split this node into....
146 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
147 (Leading _ in Macro Names, Backslash-Newline-Newline):
148 (Backslash-Newline Comments, Long Lines in Makefiles):
149 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
150 (obj/ and Make, make -k Status, VPATH and Make):
151 (VPATH and Double-colon, $< in Explicit Rules):
152 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
153 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
154 New nodes, resulting from splitup of Limitations of Make.
155 All cross-references changed. Raise the top node from
156 a section to a chapter, and all subnodes accordingly.
157 Redo the introductory wording to match the new organization.
158 (Installation Directory Variables): Use an example that is
159 closer to what Autoconf actually does. Mention that VPATH's
160 value should not contain metacharacters or white space.
161 (Fortran Compiler): Fix a VPATH bug in an example.
162 (Leading _ in Macro Names): Mention that this problem is no longer
163 of practical concern.
164 (VPATH and Make): Reword the advice to make it clearer
165 that Autoconf and Automake support VPATH in non-GNU make, but
166 many packages have bugs in this area.
167 ($< in Explicit Rules): Refer to Build Directories rather
168 than using a (non-VPATH-safe) example.
169 (Automatic Rule Rewriting): Mention the sort of disaster that
170 can ensue with Solaris-style rule rewriting with VPATH.
172 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
174 * doc/install.texi (Compilers and Options): Weaken the
175 suggestion to use GNU make for VPATH builds.
177 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
178 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
180 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
181 in regular expression.
183 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
185 * doc/autoconf.texi (Installation Directory Variables):
186 Drop extra @samp from `@table @samp' item.
187 (Limitations of Usual Tools): Comment fix.
188 Do not nest @samp just to point to other table items.
189 (Writing testsuite.at) <AT_CHECK>: The second argument to
190 `@dvar' is already @samp'ed.
191 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
192 do not use @var in the second argument.
194 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
196 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
197 $as_shell.exe too. Problem reported by Andreas Buening in
198 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
200 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
202 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
203 `unused variable' compiler warning, for `-Wall -Werror'.
204 Reported by Jaap Haitsma in
205 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
207 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
209 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
210 case the compiler dumps core. Problem reported for
211 OpenServer 5.0.7 by Tim Rice in
212 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
213 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
214 Likewise.
216 2006-06-06 Tim Rice <tim@multitalents.net>.
218 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
219 "ERROR" only shows up in "make check" output if there is an
220 error.
222 2006-06-06 Eric Blake <ebb9@byu.net>
224 * tests/tools.at (automatically allowed tokens): Fix typo.
226 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
228 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
230 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
231 typically overflows on x86 CPUs, even though the C standard
232 requires otherwise.
234 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
236 * configure.ac (AC_INIT): Bump to 2.59e.
237 * NEWS: Update.
239 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
241 Version 2.59d.
243 * config/texinfo.tex: Sync from upstream.
245 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
246 seen, invoke libtoolize with `--ltdl' argument.
247 * lib/autom4te.in (Autoreconf-preselections): Adjust.
248 * NEWS: Update.
249 Suggested by Eric Blake.
251 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
253 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
254 reported by Ralf Wildenhues.
255 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
257 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
259 * THANKS: Update.
261 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
263 * doc/autoconf.texi: Modernize some of the references to Solaris.
265 2006-06-05 Stepan Kasal <kasal@ucw.cz>
267 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
268 message issued by AC_REQUIRE.
269 * tests/m4sugar.at: Check m4_require's error message.
270 * tests/base.at: Check AC_REQUIRE's error message.
271 * tests/local.at (AT_CHECK_M4): New macro, almost identical
272 to...
273 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
274 AT_CHECK_M4.
275 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
276 `expout' as the last parameter.
277 * tests/tools.at: Adapt to the above change.
279 2006-06-04 Stepan Kasal <kasal@ucw.cz>
281 * doc/autoconf.texi (Limitations of Usual Tools): Correct
282 information about race-free implementations of mkdir.
284 2006-06-04 Eric Blake <ebb9@byu.net>
286 * bin/autoreconf.in (help): Document M4 environment variable.
287 * bin/autoconf.as (Usage): Likewise.
288 * bin/autom4te.in (help): Likewise.
289 * doc/autoconf.texi (autom4te Invocation): Likewise.
291 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
293 * NEWS: GNU make now recommended for VPATH builds.
294 Mention that some macros are now documented to be obsolescent.
295 * doc/autoconf.texi:
296 Prefer "current" to "modern" to describe
297 currently-used (albeit perhaps old-fashioned) hosts.
298 Mention which ancient features no longer need to be worried about.
299 setgid -> set-group-ID
300 setuid -> set-user-ID (these are the Posix terms)
301 Fix some misuses of "only".
302 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
303 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
304 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
305 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
306 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
307 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
308 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
309 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
310 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
311 Mention that these macros are obsolescent.
312 (Installation Directory Variables): shall -> should
313 (File Descriptors): Mention that 0, 1, 2 might get reopened.
314 Mention that it's now safe to use 3 and 4.
315 (Limitations of Usual Tools): cp -r is now specified by Posix.
316 Omit longwinded and obsolescent discussion of cp -f.
317 Modernize discussion of expr, ls.
318 (Limitations of Make): Modernize discussion of VPATH builds.
319 Mention $? as a workaround in some cases.
320 * doc/install.texi (Basic Installation):
321 Mention "./configure; make; make install" first. Be more
322 specific about why this file is generic. Remove unnecessary
323 parens. Remove misleading "only". Remove obsolete advice
324 about csh. Don't say "configure" takes awhile; say it
325 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
326 and CC=c99 rather than CC=c89, as these are blessed by current
327 Posix. Recommend GNU make if doing a VPATH build.
329 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
331 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
332 examples involving shell prompts.
334 2006-06-02 Stepan Kasal <kasal@ucw.cz>
335 and Paul Eggert <eggert@cs.ucla.edu>
337 * doc/autoconf.texi (Here-Documents): Add details about the
338 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
339 use "here-documents" instead of "here documents".
341 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
343 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
345 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
347 * doc/autoconf.texi (File System Conventions): Warn about ":"
348 anywhere in directory names.
350 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
352 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
353 about quoting the case statement, just in case.
354 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
355 was fixed in ksh93g; reported by Ralf Wildenhues.
357 2006-05-31 Stepan Kasal <kasal@ucw.cz>
359 * doc/autoconf.texi (System Services): Do not document
360 overriding EXEEXT via ac_cv_exeext=ext.
361 (Particular Programs) <AC_PROG_MKDIR_P>:
362 Document that ${MKDIR_P} understands --.
363 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
364 comment.
366 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
368 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
369 argument with leading hyphen. Problem reported by Paul Eggert.
371 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
373 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
374 about quoting ac_try: quote all of it, if any of it seems suspicious.
375 This means we don't have to worry about ${ or sed any more.
376 Also, double-quote the case statement, to work around misuses via
377 underquoting as reported by Ralf Wildenhues in
378 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
379 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
380 undocumented and dangerous macro.
381 Problem reported by Ralf Wildenhues in
382 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
384 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
386 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
387 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
388 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
390 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
392 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
393 since evidently some packages rely on the old, broken behavior.
394 Problem reported by Ralf Wildenhues in
395 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
396 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
397 pre-2006-05-26 definitions, but leave in the comments that
398 these macros are dangerous and should not be used.
399 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
400 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
401 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
402 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
403 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
405 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
407 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
408 the use of 'tr', since this is our only use of 'tr'.
410 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
411 and Paul Eggert <eggert@cs.ucla.edu>
413 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
414 Don't assume 'grep' works on long lines, since AIX grep doesn't.
416 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
418 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
419 the output file in the `${datarootdir}' test.
421 2005-05-28 Stepan Kasal <kasal@ucw.cz>
422 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
424 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
425 mention of `datarootdir' in the input file(s), but literal
426 `${datarootdir}' in the output file, and we haven't warned yet,
427 then warn as well: the user may have (erroneously) used
428 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
429 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
430 * tests/torture.at (datarootdir workaround): Extend this test.
431 * NEWS: Update.
433 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
434 and Paul Eggert <eggert@cs.ucla.edu>
436 * doc/autoconf.texi (autoheader Invocation): The first argument to
437 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
438 alternatives and clear up the language a bit.
440 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
442 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
443 ac_config_guess, ac_config_sub, ac_configure.
444 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
445 Fix typo that prevented an unnecessary space from being removed.
446 Problems reported by Ralf Wildenhues in:
447 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
449 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
451 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
452 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
453 Don't use the term "thread-safe" to talk about mkdir race
454 conditions, since the problem is more a process than a thread
455 issue. Problem reported by Stepan Kasal in:
456 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
457 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
458 the test for 'install' more closely. Look at MKDIR_P first.
459 Look in the PATH, and at /opt/sfw/bin.
460 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
461 Don't bother to try mkdir -p, since we already check mkdir --version;
462 just look at the version number. (There's no easy way to check
463 for race-free implementations.)
464 * tests/tools.at (autoconf: subdirectories): Adjust to above
465 changes, since MKDIR_P now might end in "/mkdir -p".
467 * doc/autoconf.texi (autoheader Invocation): Mention that the
468 first arg of AC_DEFINE_UNQUOTED must be a literal.
469 Problem reported by Ben Pfaff in
470 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
472 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
473 * doc/autoconf.texi (Special Chars in Variables): New section.
474 (Preset Output Variables): Warn about special chars in CPPFLAGS.
475 (Installation Directory Variables): Quote $(datadir) better.
476 (Limitations of Builtins): Describe some of eval's trickiness.
478 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
479 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
480 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
481 in front of every arg, not just trailing args. Quote apostrophes.
482 (_AC_EVAL_ECHO): New macro.
483 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
484 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
485 removed.
486 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
487 exposed by quoting of eval argument. Put the command on line line
488 so it logs better.
489 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
490 (_AC_PATH_X, AC_PATH_X): Quote more safely.
491 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
492 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
493 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
494 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
495 Use eval more safely.
496 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
497 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
498 to be replaced.
499 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
500 lines, exposed by quoting of eval argument.
502 2006-05-26 Stepan Kasal <kasal@ucw.cz>
503 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
505 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
506 initialization of `ac_cv_exeext', do not override it if it was
507 already set, unless it was set to `no', for compatibility with
508 Autoconf-2.13, and comment this.
509 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
510 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
511 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
512 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
513 Document that this test may be overridden by setting
514 `ac_cv_exeext'.
516 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
518 Revert these two patches:
520 2006-04-06 Eric Blake <ebb9@byu.net>
521 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
522 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
523 2006-04-01.
525 2006-04-01 Stepan Kasal <kasal@ucw.cz>
526 Clean up _AC_COMPILER_EXEEXT* macros.
527 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
528 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
529 ac_file to the name of the default output file and call
530 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
531 initial `rm' of the candidate files...
532 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
533 the same list in subsequent `rm' calls, and for the temporary
534 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
535 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
536 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
537 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
538 no longer needed) by libtool. Make it a cache check.
539 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
540 copied here by mistake.
541 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
542 _AC_COMPILER_EXEEXT.
543 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
544 _AC_COMPILER_OBJEXT directly.
545 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
547 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
549 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
550 Fix description of how the buggy `sed' works.
552 2006-05-25 Noah Misch <noah@cs.caltech.edu>
554 Sync from Automake:
556 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
557 ENOLCK. Only mention `make -j' when applicable. Only raise
558 fatal errors when `make -j' is involved. Improve error message.
560 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
562 * doc/autoconf.texi (Here-Documents): We now know more about
563 the variable expansion in here documents bug.
564 Thanks to Tim Rice and Stepan Kasal.
566 * doc/autoconf.texi (Making testsuite Scripts): Add an example
567 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
569 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
571 * tests/autotest.at (Multiline command from M4 expansion):
572 No failure to be expected if the shell quotes newlines in
573 commands in the `set -x' output. Report by Tim Rice.
574 * THANKS: Update.
576 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
578 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
579 expansion in the here-documents used by config.status, as that
580 runs afoul of the Korn shell version M-12/28/93d bug described in
581 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
582 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
583 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
585 2006-05-23 Jim Meyering <jim@meyering.net>
587 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
588 Fix typo introduced with 2006-04-02 change. It reversed the sense
589 of the test.
591 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
593 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
594 ac_dB slightly, to save bytes in the script.
595 Max out at 50 lines, rather than 96; this is more likely
596 (though not guaranteed) to avoid obscure 'sed' failures.
598 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
600 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
601 `tr -d -' as bad option argument. Work around this by deleting
602 an unrelated character.
603 Report by Tim Rice <tim@multitalents.net>.
605 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
606 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
607 Stepan Kasal <kasal@ucw.cz>
609 * doc/autoconf.texi (Particular Programs): Do not promise that
610 we always prefer the GNU version of the program, and that we
611 search according to PATH; both rules can have exceptions.
612 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
613 AC_PROG_SED. Move descriptions of limitations
614 to the Limitations of Usual Tools section.
615 (Limitations of Usual Tools) <sed>: Mention script length
616 limitations with Solaris /usr/ucb/sed.
617 <grep>: Fix wording for empty alternative. Mention that -c and
618 -l should not be combined, and that -E and -F should not be
619 combined.
621 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
622 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
624 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
625 limits in Solaris 8 /usr/ucb/sed by testing a long script.
627 2006-05-22 Stepan Kasal <kasal@ucw.cz>
629 * doc/autoconf.texi (Defining Symbols): Literal parameter of
630 AC_DEFINE is now passed to m4_pattern_allow.
631 * NEWS: Mention that; likewise for AC_SUBST.
632 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
633 the parameter to m4_pattern_allow.
634 * tests/tools.at: Add a check for that.
636 2006-05-22 Stepan Kasal <kasal@ucw.cz>
638 * lib/autoconf/status.m4: Fix typos.
640 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
642 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
643 only the files that this macro generates.
645 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
647 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
648 the HP-UX sed limitation of 99 commands, labels do not count.
649 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
650 in the comment.
651 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
653 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
655 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
656 Import the following fix from coreutils:
658 2006-01-13 Jim Meyering <jim@meyering.net>
660 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
661 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
662 not double-quote uses of that variable, to accommodate the rare
663 case in which getmntent is available in none of the libraries
664 checked. This happens at least on FreeBSD 5.0.
666 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
668 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
669 ac_config_guess, ac_config_sub, and ac_configure, since evidently
670 some other programs unwisely rely on these undocumented vars.
671 But put in warning comments about them.
672 Problem reported by Ralf Wildenhues in
673 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
674 * NEWS: Document that these variables are intended to go away.
676 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
678 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
679 and set the language to C++ (analogous to the equivalent Fortran
680 tests).
682 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
683 * doc/autoconf.texi (C++ Compiler): Document it.
684 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
685 * NEWS: Update.
687 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
689 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
690 that caused config.status to generate 100-command sed scripts; the
691 portable limit is 99.
693 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
695 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
696 variable `ac_d' instead of `d' to avoid infringing namespace.
697 Report by Ralf Menzel.
699 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
701 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
702 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
703 * tests/tools.at (autoconf: subdirectories): New test, taken from
704 the corresponding problem report by Ralf Wildenhues in:
705 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
707 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
708 Quote some uses of shell variables if they might suffer unexpected
709 globbing. This doesn't fix all instances of quoting problems that
710 I found, just the easy ones that look safe.
711 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
712 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
713 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
714 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
715 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
716 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
717 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
718 Likewise.
719 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
720 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
722 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
724 * bin/autoreconf.in ($help): Reword according to the manual.
725 Suggested by Olly Betts.
727 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
728 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
730 * bin/autoreconf.in: Pass the directory argument to
731 `require_configure_ac'. Fix comment.
732 * tests/torture.at (Configuring subdirectories): Expose this.
733 Reported by Olly Betts.
735 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
737 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
738 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
739 Automake as follows:
741 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
742 `$configure_in' instead of `configure.in', to preserve
743 directory component.
745 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
747 * config/config.guess, config/config.sub, config/texinfo.tex,
748 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
750 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
752 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
753 test for C99 conformance; (bool) 0.5 is an integer constant
754 expression, but (bool) -0.5 is not. Problem reported by Fedor
755 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
757 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
759 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
760 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
761 Warn about obsolete install-sh files. Remove stray sentence
762 fragment and fix cross reference.
763 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
764 install -d; this undoes the 2006-05-10 change.
765 (MKDIR_P): Mark with AN_MAKEVAR.
766 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
767 that we don't require $INSTALL to be thread-safe. Move comments
768 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
769 of AC_PROG_INSTALL. Output a message saying that we're checking
770 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
771 MKDIR_P instead of AC_SUBST.
772 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
773 Special magic for MKDIR_P, too.
774 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
775 a dnl.
776 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
778 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
780 Sync from Automake, as follows:
782 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
783 * config/install-sh: Initialize IFS, so field splitting isn't
784 turned off later.
785 * config/mkinstalldirs: Likewise.
786 * config/missing: Remove superfluous quotes. Replace all uses of
787 `[' by `test', for consistency, and for..
788 * config/missing (sed_minuso, sed_output): New variables.
789 (autom4te, help2man, makeinfo): Use them. Unifies detection of
790 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
791 Fixes `missing' to detect `--output' for help2man. Fixes
792 PR automake/483. Report by Dennis J. Linse.
793 (autom4te): Document in `missing --help'.
795 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
797 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
798 * config/install-sh: Don't use 'path' to talk about file names,
799 as per GNU coding standards. Close a race condition reported by Ralf
800 Wildenhues and Stepan Kasal. There is still a race condition
801 on hosts that predate Posix 1003.1-1992, but we can't help this.
802 Don't mishandle weird characters like space on pre-Posix hosts.
803 Invoke mkdir at most once per dir arg on pre-Posix hosts.
804 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
805 AC_PROG_MKDIR_P from AS_MKDIR_P.
806 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
807 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
808 earlier editions are not (including Automake 1.8.3).
809 Do not suggest mkinstalldirs for thread-safety.
810 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
811 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
812 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
813 presence of special characters and race conditions.
814 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
815 in Autoconf's name space.
817 2006-05-10 Bruno Haible <bruno@clisp.org>
818 and Paul Eggert <eggert@cs.ucla.edu>
820 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
821 from Automake with minor changes.
822 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
824 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
826 * config/install-sh: Update to Automake CVS version, as follows:
827 2006-04-25 Stepan Kasal <kasal@ucw.cz>
828 * lib/install-sh: Simplify the expr implementation of dirname.
829 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
830 * lib/install-sh: Handle --, and diagnose unknown options.
832 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
834 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
835 `./autom4te' to create `./testsuite', since the `all' target
836 will ensure its presence, but `installcheck' should not create
837 the uninstalled wrappers.
839 * tests/torture.at (Unusual Automake input files): Skip if we
840 detect automake < 1.8.
842 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
844 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
845 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
846 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
847 * NEWS: Update.
849 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
851 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
852 munge (multiple) white space and other oddities.
853 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
854 single quotes in variable assignment.
855 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
856 and similar failures by adding multiple spaces, tabs, and other
857 special characters.
858 Report and different test suggested by Francesco Romani
859 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
861 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
862 single quotes, we only need to search for single quotes; this
863 both simplifies the search pattern, and makes us less
864 susceptible to `echo' variations for arguments not containing
865 single quotes.
866 (_AC_ARG_VAR_VALIDATE): Likewise.
868 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
870 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
871 `$*' and IFS concatenation issue with traditional shells and
872 bash-2.04. Report by Seanster@Seanster.com.
874 2006-05-03 Bruno Haible <bruno@clisp.org>
876 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
877 precisely which Mac OS X versions have the od problem.
879 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
881 * doc/autoconf.texi: Use @option systematically.
882 (Integer Overflow):
884 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
885 and Bruno Haible <bruno@clisp.org>
887 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
888 about 'od'.
889 (Integer Overflow): Mention the special case of integer division
890 overflow.
892 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
894 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
895 traditional shells like the Solaris one that do not use the
896 first IFS character for assembling `$*'.
897 Prompted by a related report from autoconf_bug@nro.ca.
899 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
900 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
902 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
903 Mention more problems with the -e option.
905 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
907 * NEWS: Typo.
908 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
910 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
911 in URLs to improve DVI formatted output (requires texinfo 4.6).
912 (System Services, Systemology, Shellology): Likewise.
913 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
914 output.
916 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
917 continuous text.
918 (Runtime): Fix macro argument names to match description:

920 (Obsolete Macros): Likewise.
921 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
922 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
923 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
925 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

931 DVI output.
933 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
935 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
936 /bin/sh set unsorted output.
937 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
938 * tests/local.at: Likewise.
940 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
942 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
943 (Integer Overflow, Null Pointers, Buffer Overruns):
944 (Floating Point Portability, Exiting Portably): New sections.
945 (Writing Test Programs): Fix some langauge. Recommend exiting
946 with status 1, not merely nonzero. Clarify exit declaration.
947 (Run Time): Move C exit status stuff to new Exiting Portably section.
948 (Systemology): Mention Posix and levenez. Update v7 reference.
949 (Portable Shell): Mention the Posix shell.
951 2006-04-25 Stepan Kasal <kasal@ucw.cz>
953 * bin/autoconf.as (me): Replace by as_me.
955 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
957 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
958 since as_me isn't set yet.
960 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
962 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
963 a few minor bugs in this area.
965 * doc/autoconf.texi (Programming in M4sh): Comment out the
966 documentation of AS_BASENAME, for now.
967 (Shell Substitutions): Do not use AS_DIRNAME in an example.
968 (Limitations of Builtins) <basename>: Do not refer to
969 AS_BASENAME.
970 * bin/autoconf.as (me): Don't use AS_BASENAME.
971 (dir): Remove the unused variable.
972 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
973 AS_DETECT_REQUIRED. All uses changed.
974 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
975 All uses changed.
976 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
977 (AS_BASENAME): Use "basename --" to protect against leading "-".
978 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
979 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
980 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".

983 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
984 (AS_DIRNAME): Use "dirname --".
986 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
988 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
989 of "run time" and "run-time" changed to "runtime", for consistency.
990 * lib/autoconf/fortran.m4: Likewise (in comment).
991 * lib/autoconf/functions.m4: Likewise.
992 * lib/autoconf/general.m4: Likewise.
993 * lib/autoconf/headers.m4: Likewise.
995 * doc/autoconf.texi (Run Time): Document the exit status situation
996 with more accuracy and detail.
998 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1000 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
1001 Archive is not officially `GNU' any more. Update URL.
1002 (Defining Directories): Likewise
1003 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
1005 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1007 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1008 newline from the `trap' code to finish `config.log'; the NetBSD
1009 /bin/sh resets the exit status after an empty command, as
1010 documented in doc/autoconf.texi.
1011 Reported by Dalibor Topic <robilad@kaffe.org>.
1013 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1015 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1016 Suggested by Bruno Haible.
1018 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1020 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1021 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1022 Instead, just list the shells that we know work.
1023 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1024 changed. Be more cautious about the _cv_ variable.
1025 * tests/tools.at (Syntax of the shell scripts): Check the
1026 _cv_ variable once, at first, to avoid an internal autoconf error
1027 when sh -n does not work.
1029 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1031 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1033 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1035 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1036 use ">&-" since we're only 99.999% sure that this is portable,
1037 and since the MinGW bug is fixed in a different way.
1038 * lib/autotest/general.m4 (AT_INIT): Likewise.
1040 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1042 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1043 before opening config.log, to avoid hitting a bug on MinGW.
1045 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1047 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1048 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1049 This works around a MinGW bug reported by Eric Paire.
1050 Make sure that all writes to the log file append to it,
1051 rather than possibly losing data.
1052 * lib/autotest/general.m4 (AT_INIT): Likewise.
1054 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1056 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1057 description.
1059 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1061 * NEWS: Update.
1063 * configure.ac (AC_INIT): Bump to 2.59d.
1065 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1067 Version 2.59c.
1069 * Makefile.maint (news-date-check): Do not require a leading `*'
1070 before the release date in NEWS.
1072 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1073 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1075 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1076 the instantiated file do not contain the string 'datarootdir'
1077 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1078 @mandir@, replace the reference '${datarootdir}' by the value.
1079 * tests/torture.at (datarootdir workaround): New test.
1080 * NEWS: Advertise this temporary fixup.
1081 Based on a patch by Bruno Haible, reported and analyzed by
1082 Paul Eggert and Noah Misch.
1084 2006-04-12 Eric Blake <ebb9@byu.net>
1086 * tests/autotest.at (Debugging a failed test): Fix comment.
1088 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1090 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1091 all the changes since 2006-04-07.
1093 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1095 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1096 succeeded, but `ln -s file dir' failed, take care to remove the
1097 leftover target before the next test, to prevent its spurious
1098 failure; also make sure `ln file dir' works before selecting it.
1099 Thanks to Keith Marshall for pointing this out.
1100 * THANKS: Update.
1102 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1103 assignments in `at_debug_args', so that we put them correctly
1104 in the `run' script.
1105 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1106 Reported by Eric Blake.
1108 2006-04-11 Eric Blake <ebb9@byu.net>
1110 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1111 top-level tests after micro-suite has been run. Used in...
1112 (Debugging a successful test, Debugging script and environment),
1113 (Debugging a failed test): ...these new tests. The first of these
1114 is fixed by...
1115 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1116 macro, split out from...
1117 (AT_INIT): ...here, so that using -d also generates a run script.
1118 Document that -d inhibits top-level logging.
1119 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1120 inhibits top-level logging; debug scripts are created.
1122 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1123 check.
1124 * tests/autotest.at (Empty test, Empty check): New test to check it.
1126 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1127 from gcc.
1129 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1131 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1132 the files if a problem appears. Make the empty *.at files
1133 read-only, too. Proposed by Ralf Wildenhues.
1135 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1137 * config/Makefile.am: Add comment to force updated Makefile.in.
1139 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1140 space only patch to this file, this patch causes the Makefile.in
1141 files that include freeze.mk to be updated, and thus have a
1142 newer time stamp again, which in turn makes a pristine CVS
1143 checkout have correct time stamps.
1145 * Makefile.maint (cvs-sv): New macro, to be used..
1146 (config.guess-url_prefix, config.sub-url_prefix)
1147 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1148 point to CVS text checkout of Gnulib files.
1149 (copyright-check): Bump current year.
1150 (announcement): Do not hard-wire `./announce-gen'.
1151 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1152 correctly.
1153 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1154 `chmod +x'.
1155 (wget_files): Update config.guess, config.sub, texinfo.tex by
1156 `wget-update', now that their URLs work again.
1158 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1160 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1161 Problem noted by Paul D. Smith.
1163 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1165 * doc/autoconf.texi: Remove unused words from word list.
1166 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1167 .x-sc_trailing_space: New files.
1169 * doc/standards.texi: Sync from gnulib.
1171 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1172 `LIBOBJDIR' as experimental.
1174 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1175 with a target directory; it's internally implemented as `cp'
1176 anyway, but since Autoconf advertises the possibility to use
1177 a target directory when LN_S is `ln -s', we need to find out.
1178 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1179 analyzed by Keith Marshall <keith.marshall@total.com>.
1181 * THANKS: Update.
1183 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1185 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1186 confdefs.h as-is. In general, if it has backslash-newline or the
1187 like, then it doesn't work either to sort or to remove empty
1188 lines.
1190 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1192 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
1194 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
1196 * lib/autom4te.in (Automake-preselections): Preselect
1197 _AM_SUBST_NOTMAKE.
1199 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1201 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1202 apostrophe within a single-quoted string, as this is the usual
1203 tradition and is easier to read than '"'"'. Don't rely on the
1204 shell treating "$/" like '$/'. Use a more-consistent indenting
1205 style for the trap.
1207 2006-04-09 Eric Blake <ebb9@byu.net>
1209 * tests/autotest.at (Backquote command substitution),
1210 (Multiline backquote command substitution): Remove mistaken
1211 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1212 applied...
1213 (Parenthetical command substitution, Multiline parenthetical
1214 command substitution): here.
1216 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1218 Import macros from gnulib (often changing their name).
1220 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
1221 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
1222 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

1225 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
1226 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
1227 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
1228 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
1229 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
1230 The manual mentions Gnulib more prominently.
1231 * doc/autoconf.texi (Gnulib): New node.
1232 (Pointers): Add Gnulib URL.
1233 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
1234 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
1235 Gnulib section.
1236 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
1237 suggest a #define rather than a typedef for _Bool, and mention
1238 Gnulib rather than trying to substitute stdbool code.
1239 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
1240 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
1241 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
1242 AC_STRUCT_DIRENT_D_TYPE.
1243 (Particular Types): Mention stdint.h and inttypes.h as standard
1244 headers too.
1245 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
1246 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
1247 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
1248 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
1249 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
1250 (C Compiler): Move AC_C_LONG_DOUBLE to ...
1251 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
1252 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
1253 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
1254 (Coding Style). Don't mention m4_expand_once.
1255 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
1256 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
1257 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
1258 (AC_CHECK_FUNCS): Use it.
1259 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
1260 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
1261 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
1262 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
1263 (AC_HEADER_ASSERT): New macro.
1264 (AC_HEADER_STDBOOL): Don't assume "#error" works.
1265 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
1266 Catch a bug in an HP-UX C compiler.
1267 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
1268 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
1269 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
1270 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):
1271 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
1272 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
1273 New macros.
1275 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
1276 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
1278 2006-04-08 Stepan Kasal <kasal@ucw.cz>
1280 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
1281 of the warning introduced by the 2001-08-28 change.
1283 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
1284 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1286 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
1287 variables shall be overriden by the cache.
1288 * tests/torture.at (AC_ARG_VAR): Test also with a first value
1289 that contains braces.
1291 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1293 Revert the patch from 2006-04-01 and only improve
1294 _AS_DETECT_BETTER_SHELL:
1296 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1297 skip nonexistent directories.
1298 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1299 only shell candidates which exist.
1300 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1301 * lib/autotest/general.m4 (AT_INIT): No need to give three
1302 parameters to _AS_PATH_WALK.
1304 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
1305 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1307 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1308 distinguish m4sugar macros.
1309 * tests/tools.at (autoupdating with aclocal and m4_include):
1310 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1311 test case by Noah Misch <noah@cs.caltech.edu>.
1313 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1315 Revert my change from 2006-03-17, in other words:
1316 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1317 and DUALCASE=1.
1318 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
1319 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
1320 it is set.
1322 2006-04-07 Eric Blake <ebb9@byu.net>
1324 * doc/autoconf.texi (Programming in M4sh): Document that
1325 AS_MKDIR_P exits the script on failure.
1326 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1328 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1330 * config/elisp-comp, config/install-sh, config/mdate-sh,
1331 config/missing, config/mkinstalldirs: Sync from Automake.
1333 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
1334 from Automake.
1336 * doc/make-stds.texi: Sync from gnulib.
1338 2006-04-06 Eric Blake <ebb9@byu.net>
1340 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1341 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1342 2006-04-01.
1344 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
1345 Eric Blake <ebb9@byu.net>,
1346 Paul Eggert <eggert@cs.ucla.edu>,
1347 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1349 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1350 whether `set' quotes correctly: redirect stderr of the tested
1351 `set', and use a subshell, for Ultrix; use `sed' instead of
1352 `grep' for zsh `set' which may write binary output; match only
1353 at the beginning of a line, to avoid false positives.
1354 In order to avoid false positives by unrelated variables with
1355 multiline content, put the dump algorithm in a subshell and
1356 unset all variables containing newlines (except some which are
1357 special to the shell). Warn about cache variables that are
1358 unset.
1360 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1362 * config/config.guess, config/config.sub, config/texinfo.tex:
1363 Sync from upstream.
1365 * tests/mktests.sh: Reword comments.
1367 * tests/mktests.sh: Only skip internal macros starting with
1368 `_AC_' or `__AC_'. Noted by Stepan Kasal.

1561 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1562 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1563 ac_file to the name of the default output file and call
1564 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1565 initial `rm' of the candidate files...
1566 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1567 the same list in subsequent `rm' calls, and for the temporary

1570 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1571 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1572 no longer needed) by libtool. Make it a cache check.
1573 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1574 copied here by mistake.
1575 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1576 _AC_COMPILER_EXEEXT.

1613 subordinate tools.
1614 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
1615 * doc/autoconf.texi (autoreconf Invocation): Document it.
1617 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

2283 `tmp' to avoid file removal race.
2285 2005-11-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2287 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
2288 ac_clean_files and LIBOBJS.
2290 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2292 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
2293 Factor functionality to..
2294 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
2295 `AC_SUBST($1)' in the public version.
2296 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
2297 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
2298 ac_pt_* variables.
2300 2005-11-01 Stepan Kasal <kasal@ucw.cz>
2302 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
2303 filesystems.
2305 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2307 * NEWS: Move AH_HEADER mention to right place.
2309 2005-10-27 Stepan Kasal <kasal@ucw.cz>
2311 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
2312 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
2314 2005-10-25 Stepan Kasal <kasal@ucw.cz>
2316 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
2317 conftst2.$ac_objext.
2318 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
2320 2005-10-24 Stepan Kasal <kasal@ucw.cz>
2322 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
2323 conftest.o, to see whether the compiler really obeys; rm the object
2324 file before and after the test and register it with ac_clean_files.
2325 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
2327 2005-10-21 Stepan Kasal <kasal@ucw.cz>
2329 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
2330 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
2331 code so that the most common case requires less forks.
2333 2005-10-20 Stepan Kasal <kasal@ucw.cz>
2335 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
2336 not portable; thanks to Paul Eggert and Alexandre.
2338 * NEWS: Fix an old typo.
2340 2005-10-20 Jim Meyering <jim@meyering.net>
2342 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
2343 the latter'', in two places.
2345 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
2347 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
2348 AC_LANG_PROGRAM, fixing a typo. Don't give details about
2349 the inner workings of AC_LANG_FUNC_LINK_TRY.
2350 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
2351 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
2352 by the function rather than ignoring it.
2353 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
2354 comparing its address. Intel's interprocedural optimization was
2355 outsmarting the old heuristic. Problem reported by
2356 Mikulas Patocka.
2358 2005-10-19 Stepan Kasal <kasal@ucw.cz>
2360 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
2362 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
2364 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

2367 2005-10-04 Stepan Kasal <kasal@ucw.cz>
2369 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
2370 before removing it (chmod -R u+rwx); there are three instances of this.
2372 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2373 Stepan Kasal <kasal@ucw.cz>
2375 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
2376 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
2377 make its content writable before removing it. Remove an errorneous
2378 comment from the end, where the logs of the failed tests are copied
2379 to the main log file.
2381 2005-09-27 Stepan Kasal <kasal@ucw.cz>
2383 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
2384 in case the computer is too quick. Double quote the configure.ac
2385 snippets.
2387 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
2388 problems if the testsuite were running too fast.
2390 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2392 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2393 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2394 (which belong to Xt, not X itself). See Debian bug 327655.
2395 * NEWS: Mention this.
2397 2005-09-07 Stepan Kasal <kasal@ucw.cz>
2399 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
2401 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
2403 * config/move-if-change: Don't output "$2 is unchanged";
2404 suggested by Ben Elliston. Handle weird characters correctly.
2406 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2408 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2409 calls, so that the final expansion of this macro is shorter.
2410 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2411 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2412 the cleanup there. Use AS_VAR_* macros, to be more general.
2413 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2415 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2417 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
2419 2005-09-01 Stepan Kasal <kasal@ucw.cz>
2421 * doc/autoconf.texi (Configuration Headers): Add an index entry
2422 for AH_HEADER.
2424 2005-08-26 Pavel Roskin <proski@gnu.org>
2426 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
2427 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
2428 running xmkmf.
2430 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
2432 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2433 The previous patch didn't work, so try a better one.
2435 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2437 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
2438 in the example. Reported by Bruno Haible.
2439 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2440 "if $undefined_var;" succeeds with my shell.
2442 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2443 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2444 but change the m4_divert_text to m4_divert_once.
2446 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
2448 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2449 Work around bug in Solaris /usr/xpg4/bin/awk.
2450 The bug is present in at least Solaris 8 through 10.
2452 2005-08-24 Stepan Kasal <kasal@ucw.cz>
2454 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2455 some evil values and relying on the fact that $* concatenates the
2456 parameters by the first character from IFS.
2458 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2459 Stepan Kasal <kasal@ucw.cz>
2461 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
2462 first header appears, define AH_HEADER.
2463 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2464 Update limitations about when to call AC_CONFIG_HEADERS.
2465 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2466 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2467 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2468 ``Configuration Actions''; fix their index entries.
2470 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2471 options correctly. Process N-M as M-N if M is smaller than N.
2472 Process ranges correctly so that N-N will run only N.
2473 Sort and uniquify the tests that will be run. If there is more
2474 than one test, reinsert the banners for the tests.
2475 * tests/autotest.at (Keywords): Unmark XFAIL.
2477 2005-08-23 Stepan Kasal <kasal@ucw.cz>
2479 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
2480 before passing the macro name to AH_TEMPLATE.
2482 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2483 now opens log after option processing; in particular, --version
2484 and --help do not touch config.log.
2486 * Makefile.maint: Revert the change from 2005-08-12.
2488 2005-08-22 Stepan Kasal <kasal@ucw.cz>
2490 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
2491 common code to...
2492 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
2494 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2496 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
2497 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
2498 Language cleanup.
2500 * doc/autoconf.texi (Defining Symbols, Changed Results):
2501 Prepend to LIBS, not append, in examples.
2503 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2505 When building in place, set srcdir="."; suggested by Tim Van Holder.
2507 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2508 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2509 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2510 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
2511 does not mean "no --srcdir option".
2513 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2515 * tests/autoscan.at (autoscan): New file.
2516 * tests/suite.at: Use it.
2517 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
2518 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
2520 * tests/autotest.at (Keywords): Test keywords combinations.
2522 2005-08-12 Stepan Kasal <kasal@ucw.cz>
2524 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2525 add "2>&1"; gzip 1.2.4 prints help on stderr.
2527 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2529 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2530 was pushdef'ed twice while popped only once. Push it only once.
2531 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
2533 2005-07-26 Stepan Kasal <kasal@ucw.cz>
2535 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

2540 * Makefile.maint: Update from Bison.
2542 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
2543 "<tab>" in comment, so that the point is understandable.
2545 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2547 Rewrite substantial part of lib/autoconf/status.m4.
2548 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2549 and CONFIG_COMMANDS are not processed in four separate loops.
2550 Instead, there is one main loop. This alows that the common code
2551 is expanded only once, thus config.status (and configure) is smaller.
2553 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2554 the AC_LIST_FILES and cousins macros are no longer used.
2556 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2557 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2558 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2559 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2560 contain the initialization, nor the for loop, nor the associated
2561 commands; all these go to ...
2562 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2563 _AC_OUTPUT_CONFIG_STATUS.
2564 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2565 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2566 (_AC_OUTPUT_FILE): The creation of the sed script ...
2567 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2568 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2569 _AC_OUTPUT_MAIN_LOOP.
2570 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2571 _AC_CONFIG_COMMANDS): Use ...
2572 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2573 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2574 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2575 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2576 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2577 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2578 ... new macros.
2579 (_AC_CONFIG_UNIQUE): Update.
2580 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2581 Replaced by this ...
2582 (_AC_LIST_TAGS): ... new common macro.
2583 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2584 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2585 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2586 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2587 this didn't belong to the `config commands' section.
2588 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2589 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2590 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2591 to the `config commands' section either.
2592 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2593 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2595 ... and many changes to the comments nearby.
2597 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
2598 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
2599 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2600 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
2601 (#define header templates): The comment at the top of the generated
2602 header now includes the name(s) of the source file(s).
2604 Several unrelated small changes:
2606 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2607 parameter to AC_DIAGNOSE.
2608 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2609 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2610 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2611 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2612 with AU::AC_OUTPUT.
2613 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2614 in AC_OUTPUT doesn't double-quote it either.
2615 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
2616 parameters.
2618 2005-07-10 Stepan Kasal <kasal@ucw.cz>
2620 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
2621 versions of Portland Group compiler produce single- and double-quoted
2622 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
2623 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
2625 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2627 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2628 This is a corrected version of yesterday's patch.
2630 2005-07-07 Stepan Kasal <kasal@ucw.cz>
2632 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
2633 path, too; insert a "===" to emphasize the line.
2635 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
2636 ac_cv_build_alias to ac_build_alias.
2637 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
2639 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
2640 change eliminates it. Problem reported by Alexandre Duret-Lutz.
2641 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
2642 (AC_ARG_VAR): ... here.
2643 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
2644 target_alias.
2646 Keep a list of all precious variables and process them with one simple
2647 for loop, instead of expanding all commands, or, OTOH, complicated
2648 processing of output of "set".
2649 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
2650 variable names in new macro...
2651 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
2652 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
2653 a loop to assign all ac_env_* and ac_cv_env_* variables.
2654 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
2655 to INIT_PREPARE.
2656 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
2657 its value to shell variable ac_precious_vars and call
2658 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
2659 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
2660 _AC_ARG_VAR_VALIDATE.
2662 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
2663 and the AC_SUBSTs ...
2664 (AC_INIT): ... here.
2666 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
2667 the ac_subst_files section in config.log.
2669 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
2671 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

2676 * tests/c.at (C keywords): Test AC_C_TYPEOF.
2678 Fix problems reported by Nicolas Joly.
2679 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
2680 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2681 They are generated by the Tru64 v5.1B shell.
2683 2005-07-05 Stepan Kasal <kasal@ucw.cz>
2685 Fix my changes from 2005-07-01; reported by Noah Misch.
2686 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
2687 description, the macro now accepts only a single tag.
2688 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
2690 Fix cases when the varsions of Autoconf and Autotest don't match.
2691 Reported by Noah Misch.
2692 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
2693 at_top_builddir, for compatibility with older autotest.
2694 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
2695 is not set, use at_top_builddir, for compatibility with older
2696 versions of autoconf.
2698 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
2700 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
2701 Problem reported by Patrick Welche.
2703 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
2705 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
2706 sed substitution command, so that we allow | in program prefixes
2707 and program suffixes. (& is a problem anyway; we're not fixing
2708 that here.)
2709 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
2710 configure_input, top_builddir, srcdir, etc.
2711 * lib/autotest/general.m4 (AT_INIT): Likewise, for
2712 PATH_SEPARATOR in AUTOTEST_PATH.
2714 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
2716 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
2717 for loop over config.site files using `set', to allow
2718 directory names containing IFS characters.
2720 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
2722 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
2723 directories with weird names. Apparently some people like living
2724 on the edge. However, improve the test that "pwd" actually does
2725 report a name for the working directory.
2726 * NEWS: Remove the claim that we test for funny chars in dir names.
2728 2005-07-01 Stepan Kasal <kasal@ucw.cz>
2730 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
2731 replaced ...
2732 * lib/m4sugar/m4sugar.m4 (m4_foreach_w): ... by this new macro.

2742 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
2744 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
2745 document to output the default config_* lists to config.status.
2746 Don't recognize option --file, if the functionality is not there.
2747 Likewise for --header; moreover, recognize --he and --h as shortcuts
2748 for --help in that case.
2750 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
2751 matches the order of execution. No code changed.

2774 (AC_SUBST): Call it.
2775 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
2776 the directory specific variables; but don't call it for configure_input.
2778 2005-06-28 Derek Price <derek@ximbiot.com>
2780 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
2781 addition.
2783 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
2785 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
2786 directory have inherent problems with special characters like spaces,
2787 due to limitations in Make syntax. Problem reported by Alexandre
2788 Duret-Lutz.
2789 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

2804 variable into diagnostic. Make the diagnostic an error, not a warning,
2805 because we really don't support spaces and suchlike in dir names.
2806 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
2807 Don't worry about backslashes in srcdir; it can't happen now.
2808 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
2809 Simplify ac_optarg handling.

2832 2005-06-21 Stepan Kasal <kasal@ucw.cz>
2834 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
2835 b, t, r, w commands require single space, while : cannot have any.
2836 (Special Shell Variables): Fix sed code this in the example.
2837 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
2838 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
2840 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
2841 expand to the empty list. Don't use two pairs of m4_changequote,
2842 it's not necessary.
2844 2005-06-20 Derek Price <derek@ximbiot.com>
2846 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
2848 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
2850 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
2851 * doc/autoconf.texi:
2852 Don't mention Solaris versions so much, if a
2853 problem is common to all extant versions of Solaris. Say "SunOS
2854 4" instead of "SunOS" for SunOS 4.
2855 (awk): Mention more of the limitations of traditional Awk.
2856 (cat): Don't talk about cat -v.
2858 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
2860 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
2861 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

2863 to be compatible with glibc strverscmp.
2864 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
2866 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
2867 on Mac OS X 10.4 reported by Peter O'Gorman in:

2869 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
2870 Use shell builtins rather than 'expr', to work around expr bug.
2872 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
2874 * doc/autoconf.texi: "filesystem" -> "file system".
2875 "behaviour" -> "behavior".

2877 * lib/autoconf/general.m4: Omit blank after ":" sed command,
2878 as per POSIX.
2879 * lib/m4sugar/m4sh.m4: Likewise.
2880 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
2881 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
2883 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
2884 (.x.1): Ignore the time stamp in the .TH line when deciding whether
2885 to update the man page. That way, we don't have to check in new
2886 man pages every month.
2888 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
2889 quotes and backslashes. Patch from Derek Price.

2893 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &
2894 AS_TR_SH.
2896 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
2898 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
2899 -u, since it outputs chatter if the input files are the same.
2900 Problem reported by Ralf Menzel.
2902 2005-06-08 Derek Price <derek@ximbiot.com>
2904 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
2905 renaming them since they are about to be redefined anyhow.
2907 2005-06-08 Derek Price <derek@ximbiot.com>
2909 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
2910 redefined M4 macros to this node. Document m4_include & m4_sinclude.
2911 Move m4_undefine to alphabetical order.
2913 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
2915 * README: Recommend GNU M4 1.4.3 or later.
2916 * doc/autoconf.texi (Introduction): Likewise.
2917 Reword to avoid some formatting glitches.
2918 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
2919 Clarify explanation of HP compiler bug.
2920 Redo example output tp match current CVS snapshot.
2921 Use @example.org in email addresses when the examples
2922 might get inadvertently cut-and-pasted into user code.
2923 Remove example of autom4te usage that doesn't seem to work now.
2924 Use modern AC_INIT (except when the example is meant to be
2925 shown with Autoconf 2.13).
2926 Update ksh info for Solaris 9 and later.
2927 KB -> kB.
2928 Modernize description of Automake versions a bit.
2929 Don't claim a future version of Autoconf is near.
2930 * doc/install.texi: Reword to avoid some formatting glitches.
2932 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2934 * doc/autoconf.texi: Add [] to examples, so that the manual
2935 follows its own advice about quoting better.
2936 Reword to avoid some formatting glitches.
2937 * doc/installt.exi: Reword to avoid some formatting glitches.
2939 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
2940 Tru64 ksh pattern matching bug. Reported against Libtool by
2941 Albert Chin <libtool@mlists.thewrittenword.com> and
2942 Nicolas Joly <njoly@pasteur.fr>.
2944 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2946 m4_cdr of one-member list was [[]] (one-member list containing an
2947 empty string) instead of [] (an empty list. Callers were skewed to
2948 match this misbehaviour. As a consequence of this:
2949 - m4_foreach([x], [], [foo]) expanded to `foo', while
2950 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
2951 This bug has been fixed:
2953 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
2954 expand to an empty string; print error msg if called without
2955 an argument list.
2956 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
2957 misbehaviour; handle [] and [[]] correctly.
2959 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2961 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

2963 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
2965 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
2967 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
2968 swallow records with more than 99 fields.
2969 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
2970 parse the long line.
2972 2005-06-04 Stepan Kasal <kasal@ucw.cz>
2974 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
2975 swallow literals longer than 399. Reported by Ralf Wildenhues.
2976 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
2977 to workaround this limitation.
2979 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
2981 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
2982 to gfortran, and make these the first two compiler names
2983 checked (following the general autoconf preference for gcc).
2985 2005-06-03 Stepan Kasal <kasal@ucw.cz>
2987 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
2988 (DISTCLEANFILES): Remove $(check_SCRIPTS).
2989 (testsuite): Make sure autotest.m4f is up-to-date before using it.
2991 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
2993 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
2994 expression of unbounded size when processing the --list
2995 option. This runs afoul of a limit of 399 bytes per regular
2996 expression on AIX. Problem reported by Ralf Wildenhues.
2998 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

3001 * doc/autoconf.texi (Particular Headers): Reword example
3002 for multiline stdbool replacement.
3003 (Setting Output Variables): Reword text a bit. Don't
3004 give all the details about |#_!!_#|.
3005 Reword description of line replacement.
3007 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3009 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3010 now contain newlines, and substituted files must be referenced on
3011 a line alone; the sed scripts to substitute them are now very
3012 different.
3013 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
3014 commands can be put in a sed script portably.
3015 * doc/autoconf.texi (Setting Output Variables): Document above
3016 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
3017 use of multiline substitution.

3027 * tests/local.at: Don't attempt to check for negated character
3028 classes in shell scripts. The test was too brittle.
3030 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3032 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
3033 * doc/autoconf.texi (Limitations of Builtins): Document this
3034 limitation.
3036 2005-05-24 Stepan Kasal <kasal@ucw.cz>
3038 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
3039 common code; used in many places in the tree.

3043 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
3045 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
3046 messages when ac_unique_file is not found.
3047 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
3048 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
3049 commands, for consistency with AC_MSG_ERROR and such.
3051 * bin/autoconf.as: Make more use of "shift 2" in option processing.
3053 * bin/Makefile.am: Merge the two rules for creating scripts.

3061 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3063 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
3064 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
3065 (ac_top_builddir): ... this ...
3066 (ac_top_build_prefix): ... to this; the old name is also kept, for
3067 backward compatibility.
3068 (ac_top_builddir_sub): New variable, without the trailing slash,
3069 always nonempty.
3070 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
3071 * doc/autoconf.texi (Configuration Actions): Rename
3072 ac_top_builddir to ac_top_build_prefix.
3073 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

3084 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3085 argument to m4_foreach. I guess it was necessary in the past,
3086 but I think it's a no-op now.
3088 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3090 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3091 ``cat <<_ACEOF'' commands to one.
3092 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
3093 * lib/autoconf/status.m4: On various places, use expr instead of
3094 ``echo|sed.''
3095 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
3096 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
3097 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
3098 a range.
3099 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
3100 the wrong patterns between ``case'' and ``esac.'' The previous
3101 code had false positives.
3103 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
3105 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
3106 as on 2005-05-02.

3169 * doc/autoconf.texi (Autoconf Language): Be more precise about
3170 quoting rules. Problems noted by Stepan Kasal.
3171 Also, throughout this document, be more careful about white space.
3172 "blank", "white space", and "space" all have different meanings
3173 and we should be careful to say what we mean.
3175 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>

3184 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
3186 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3188 * doc/autoconf.texi (Generic Functions): Typos.
3190 2005-05-02 Gary V. Vaughan <gary@gnu.org>
3192 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
3193 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
3194 set by latest automake.
3196 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
3198 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
3199 outputs 0 on GNU/Linux these days.
3201 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
3203 * doc/autoconf.texi (Autoconf Language): Add more description
3204 about quoting heuristics.
3205 (Limitations of Builtins): Describe "set -" problems.
3207 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3209 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
3210 not newline.
3212 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
3213 by AC_DEFINE; it was a mistake.
3214 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
3216 2005-04-25 Stepan Kasal <kasal@ucw.cz>
3218 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
3220 2005-04-22 Stepan Kasal <kasal@ucw.cz>
3222 * doc/autoconf.texi (External Software): Quadrigraphs are not
3223 processed correctly in AS_HELP_STRING; avoid this in the examples.
3224 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
3225 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
3226 comment and reduce m4_default([foo], []) to [foo].
3227 (m4_strip): Update the explanation.
3229 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3231 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
3232 Remove core.conftest.* too; it's generated by Tru64 5.1.
3233 Problem reported by Jennis Pruett.
3234 * lib/autoconf/functions.m4
3235 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3236 Don't bother to remove core files; AC_RUN_IFELSE should do that
3237 for you.
3239 2005-04-19 Stepan Kasal <kasal@ucw.cz>
3241 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

3258 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
3260 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
3261 as well as configure.in. Problem reported by Gregorio Guidi.
3263 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
3265 * doc/autoconf.texi (Particular Functions): Use gnulib's current

3281 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3283 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
3284 Merge `-z option' as well for the benefit of Solaris link flags. Pass
3285 whole-archive (-zallextract, -zdefaultextract) options in the hope of
3286 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
3287 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
3289 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
3291 * NEWS: The configure command now warns you if you attempt to use
3292 a directory whose name contains a special character like space,
3293 newline, or "\".
3294 * doc/autoconf.texi (Installation Directory Variables): Allow
3295 "," in file names. Do not use \@; it's not a portable regexp.
3296 * bin/Makefile.am (edit): Likewise.
3297 * lib/Makefile.am (edit): Likewise.
3298 * tests/Makefile.am (edit): Likewise.
3299 * tests/semantics.at: Likewise.
3300 * tests/torture.at: Likewise.
3301 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
3302 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
3303 * doc/autoconf.texi (File System Conventions): Warn about
3304 unportable file names.
3305 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3306 (AC_INIT): Use it.
3307 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3308 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3309 ac_pwd, and quote srcdir.
3310 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3312 * doc/autoconf.texi: Fix some systematic formatting problems.
3313 ".)" needs a following @: if not at the end of a sentence, and
3314 similarly for "!)". "etc." should be preceded by a comma.
3315 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3317 2005-03-22 Bruno Haible <bruno@clisp.org>
3319 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3320 argument is often called 'build-aux'.
3322 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3324 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3325 macro AC_TRY_LINK is obsolete.
3326 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3327 `AC_CONFIG_FILES'.
3329 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3331 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3332 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3333 from a Common Lisp's `cl'.
3334 (AC_PROG_CXX): Behave according to the documentation: don't
3335 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3336 make the variable CCC precious; use `cl.exe', not `cl'.
3338 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3339 Alexandre Duret-Lutz <adl@gnu.org>
3341 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3342 /dev/null, as "configure" shouldn't read stdin, and this insulates
3343 us from problems (e.g., when testing for "cl"). Also, do this
3344 redirection before invoking "hostname" or "uname", and keep the
3345 original input stream available via...
3346 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3347 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3348 bother with "</dev/null" since it's now done at the top of
3349 'configure'.
3350 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3351 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3352 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3353 * doc/autoconf.texi (File Descriptor Macros): New section.
3354 (Printing Messages): Mention it.
3355 * tests/base.at (Input/Output): New test.
3357 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3359 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3360 newline if neither \c nor -n work, as that would output two
3361 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3363 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3365 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3366 This causes that any required macros inside will get before the if.
3367 * doc/autoconf.texi (autom4te.cache): A typo.
3369 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3371 Undo previous change, except keep the change to
3372 lib/autoconf/programs.m4 that replaced grep with shell
3373 pattern-matching. This is because net-snmp configure reads stdin.
3374 Reported by Noah Misch.
3376 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3378 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3379 from /dev/null, as "configure" shouldn't read stdin, and this
3380 insulates us from problems (e.g., when testing for "cl").
3381 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3382 before invoking "hostname" or "uname".
3383 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3384 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3385 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3386 "</dev/null" since it's now done at the top of 'configure'.
3387 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3388 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3389 Also, replace grep with shell pattern-matching, to save a process.
3391 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3393 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3394 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3395 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3396 compiler.
3398 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3400 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3401 grep -q isn't portable. Improve grep -s explanation.
3402 Problem reported by Dan Manthey.
3404 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
3406 * doc/autoconf.texi (Special Shell Variables): Clarify
3407 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
3409 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
3411 * doc/autoconf.texi: Use @acronym for DJGPP.
3412 Fix some @code's that should have been @env's, and vice versa.
3413 Sort environment variable names.
3414 Mention that shells no longer inherit IFS.
3415 Don't recommend PATH_SEPARATOR=';' so strongly.
3416 Mention that $RANDOM might expand to the empty string.
3417 "symlink" and "soft link" -> "symbolic link".
3418 Improve mktemp description (reported by Bruno Haible).
3420 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
3422 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
3423 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
3424 Likewise.
3425 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
3426 Likewise.
3428 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
3430 * NEWS: Mention AT_COPYRIGHT.
3432 * tests/local.at (AT_CMP): Use diff directly on input files rather
3433 than copying them.
3435 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
3436 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
3438 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3439 and Paul Eggert <eggert@cs.ucla.edu>
3441 * tests/autotest.at (Empty test suite): New test.
3442 * tests/torture.at (Substitute and define special characters)
3443 (Substitute a 2000-byte string, Define to a 2000-byte string)
3444 (Substitute a newline, Define a newline): New tests.
3446 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3448 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
3449 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
3450 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
3451 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
3452 (Standard regular expressions): New test.
3453 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
3454 excess test name quoting.
3455 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
3456 CPPFLAGS to `configure' instead of setting it in `configure'.
3458 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
3459 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
3460 on some platforms.
3462 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
3463 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
3465 * tests/local.at (AT_CMP): New macro.
3466 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
3467 (AC_SAVE_STATE): Move environment grep...
3468 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
3469 (AT_CONFIG_CMP): New macro.
3470 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
3471 * tests/c.at (Extensions): Do not exit early.
3472 * tests/atlocal.in: Inherit $GREP.
3474 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
3475 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
3477 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
3478 (AC_COPYRIGHT): Factor header comment portion out and move into...
3479 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
3480 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
3481 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
3482 --version output.
3483 * tests/local.at: Add Autoconf test suite copyright notice.
3484 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
3486 2005-02-04 Bruno Haible <bruno@clisp.org>
3487 and Paul Eggert <eggert@cs.ucla.edu>
3489 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
3491 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
3493 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
3494 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
3496 Try not to generated lines of unlimited length, as POSIX places a
3497 2047-byte limit on line length of portable text files.
3498 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
3499 Use newline as a separator, not space.
3500 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
3501 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
3502 space.
3504 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3506 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
3507 as_func_*. Add test to check whether positional parameters
3508 are restored after function return.
3510 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
3512 * doc/autoconf.texi (Special Shell Variables): Mention _,
3513 BIN_SH, DUALCASE. Say that variables other than "status" are safe
3514 if they contain a lower-case letter. The DUALCASE problem was
3515 reported by Ralf Wildenhues.
3517 * bin/autoconf.as: Don't exit with status 0 after write failure
3518 with --help or --version.
3519 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
3520 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
3522 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3524 * doc/autoconf.texi (Limitations of Usual Tools):
3525 Unicos 9 sed limitations.
3526 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
3527 to get the option-enhanced interface on older Crays. Try ftn for
3528 Fortran 95 (newer Crays).
3530 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
3532 * man/Makefile.am (.x.1): Go back to the simple solution, but take
3533 care to echo the commands, so the user knows what's going on.
3534 Modified from a suggestion by Stepan Kasal.
3536 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
3537 with a cross reference. Derived from a suggestion by Bruce Korb.
3539 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
3541 * doc/autoconf.texi (config.status Invocation): Warn about
3542 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
3543 * doc/install.texi (Defining Variables): Likewise.
3544 Based on a proposed patch by Ralf Wildenhues.
3546 * man/Makefile.am (.x.1): Make sure the required generated files
3547 are up to date. Problem and original solution proposed by Stepan Kasal.
3548 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
3549 implicit-man-prerequisites): New rules, used by the above.
3551 * doc/make-stds.texi, doc/standards.texi: Sync from gnulib.
3552 * config/config.guess, config/config.sub, config/install-sh: Likewise.
3553 * config/missing, config/texinfo.tex: Likewise.
3555 2005-01-29 Stepan Kasal <kasal@ucw.cz>
3557 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3558 Update the long comment explaining it.
3560 m4_require no longer writes an ``is required by'' line to the
3561 execution stack. It contains only one bit of non-redundant
3562 information: that the macro was required, not called. And even
3563 this bit is useless in most situations: have you ever met a macro
3564 which both calls and requires the same macro?
3566 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3567 (_m4_defun_pro_outer): ... only via this macro, for the outermost
3568 macro.
3569 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
3570 (m4_expansion_stack_pop): Remove the misplaced comment.
3571 (m4_require): Don't put the ``is required by'' line to the
3572 execution stack; slightly improve the out-of-a-defun error message.
3573 (_m4_divert_grow): New macro, counter for the temporary diversions.
3574 (_m4_require_call): Use it.
3575 * tests/m4sugar.at (m4_require): Expect output without the
3576 ``is required by'' messages.
3578 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
3580 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
3581 rather than x for expr.
3583 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
3584 this is safe.
3585 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
3586 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
3587 * lib/autotest/general.m4 (AT_INIT): Likewise.
3588 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Likewise.
3589 * tests/mktests.sh: Likewise.
3591 2005-01-27 Akim Demaille <akim@epita.fr>
3593 Have autoheader honor --force.
3595 * doc/make-stds.texi, doc/standards.texi: Update from masters.
3596 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
3597 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
3598 from masters, so that FileUtils.pm's update_file provide --force
3599 support.
3600 * bin/autoheader.in: Pass $force to update_file so that
3601 config.h.in is always recreated when --force.
3603 2005-01-24 Stepan Kasal <kasal@ucw.cz>
3605 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
3607 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
3609 * doc/autoconf.texi (Limitations of Builtins): Clarify that
3610 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
3612 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
3614 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3615 Warn about newline stripping in `` and $(). Update Solaris
3616 version to 9.
3617 (Limitations of Builtins): Use expr "X...", not expr "x...", as
3618 X insulates us from future changes to Posix.
3619 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
3620 stripping.
3622 2005-01-19 Stepan Kasal <kasal@ucw.cz>
3624 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
3625 you cannot use AC_DEFINE to define macros containing `[' or `]'.

3986 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
3987 "char c = '\200';" rather than "char c = 0x80;" as the

4092 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
4093 Problem reported by Stepan Kasal.
4095 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>

4098 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
4099 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
4100 in test makefile.
4101 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
4102 readable; it's not true in OS/2-emx.
4104 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
4106 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
4107 "/usr/include", clear ac_x_includes instead of leaving it as "no"
4108 (trivial change). Problem and patch reported by Andrew Church in:
4109 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
4111 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
4113 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
4114 three args in examples. Problem reported by Frederik Fouvry in:
4115 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
4116 Also, fix some minor spacing and punctuation bugs.
4118 2004-09-02 Akim Demaille <akim@epita.fr>
4120 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
4121 "case" to restore ordering.
4122 Reported by Stepan Kasal.
4124 2004-08-26 Akim Demaille <akim@epita.fr>

4138 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
4139 texinfo.tex for now (done by hand now).
4140 * Makefile.maint (wget_files, cvs_files):
4141 Remove ansi2knr.c; nobody uses it.
4142 (ansi2knr.c-url_prefix): Remove.
4143 (cvs-update): Fix test for failure. I don't know why it ever
4144 worked...
4146 * doc/autoconf.texi: Update URLs, some of which went stale.
4147 Use @uref rather than @href.
4149 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
4150 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
4152 * config/config.guess, config/config.sub, config/elisp-comp,
4153 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
4154 doc/fdl.texi, doc/standards.texi: Sync with master copy.
4156 * NEWS, TODO, configure.ac, bin/autoscan.in,
4157 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
4158 doc/install.texi, lib/Autom4te/Configure_ac.pm,

4162 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
4163 tests/tools.at, tests/torture.at:
4164 Use "file name" rather than "filename" or "path",
4165 to be consistent with the terminology of the GNU coding standards.
4167 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
4169 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
4170 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
4171 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
4172 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
4174 More fixes to support spaces in the name of the build directory.
4175 This isn't a complete fix but it's an improvement.
4177 * bin/autoconf.as (autom4te_options): New var.
4178 Use it instead of appending to AUTOM4TE, so that we can allow
4179 spaces in the build directory's absolute name.
4180 * bin/autoheader.in ($autoconf): Allow spaces in file names.
4181 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
4182 AT_CHECK_NOESCAPE): Likewise.
4183 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
4184 main program): Likewise.
4186 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
4188 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
4189 From Ralf Corsepius in:
4190 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
4192 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
4194 * doc/autoconf.texi (Function Portability): Document isinf and
4195 and isnan. From a suggestion by Kevin Ryde.
4197 * lib/Autom4te/General.pm (END): Return correct exit status even
4198 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
4200 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
4202 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
4203 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
4204 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
4206 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
4208 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
4209 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
4210 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
4211 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
4212 * lib/autom4te.in (Automake-preselections): Preselect
4213 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4215 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4217 * lib/autom4te.in (Automake-preselections): Preselect
4218 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4219 trace them.
4221 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4223 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4224 Tru64.
4225 * doc/autoconf.texi (Shellology): Mention BIN_SH.
4226 Document problem with "`""`" in pdksh POSIX mode.
4228 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4230 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4231 with pdksh, too. Problem reported by Patrick Welche via
4232 Gary V. Vaughan.
4233 * doc/autoconf.texi (Shellology): Note that set -o posix is
4234 useful for pkdsh, too.
4236 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4238 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
4239 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
4240 Don't fail if ENV or BASH_ENV is readonly.
4241 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4242 etc. are read only. Problem reported by Ludovic Courtes.
4244 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4246 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
4247 zsh, disable GLOB_SUBST to avoid backslash handling problems.
4248 (trivial change)
4250 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4252 * doc/autoconf.texi (File System Conventions): Warn about
4253 names like "aux". Problem reported by Eric Blake.
4255 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4256 by zero instead of array size, so that we can use any arithmetic
4257 constant expression (instead of requiring an integer constant
4258 expression). This allows us to test expressions like DBL_MAX <
4259 LDBL_MAX, which didn't conform to the C standard using the old
4260 method.
4261 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4262 now that we can do floating-point tests at compile time.
4264 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4266 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4267 and LDBL_EPSILON, as the resulting expression isn't an
4268 integer constant expression and violates the C standard.
4269 Problem reported by Nelson H. F. Beebe. Also, check
4270 for "L" suffix, and check that long double doesn't have
4271 worse range or precision than double, that mixed-mode
4272 arithmetic doesn't generate a diagnostic, that double
4273 constants fit in long double.
4275 2004-06-03 Kevin Ryde <user42@zip.com.au>
4277 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4278 malloc(0) and realloc(NULL,size).
4280 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4281 Bob Proulx.
4283 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4285 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4286 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4287 by Jim Meyering.
4289 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4291 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4292 can be rewritten using if-then-else. Suggested by Bruno Haible.
4294 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4296 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4297 Problem reported by Stepan Kasal.
4299 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4301 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4302 change). Patch reported by Ralf Wildenhues in
4303 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4305 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4306 function F exists if the compiler and linker let you compile an
4307 expression like (F != 0). Recent versions of GCC optimize away
4308 the reference to F in that case, since every function address must
4309 be nonzero, so the link succeeds even if F does not exist.
4310 Problem reported by Manu in
4311 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4313 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4314 "Unix". Many uses changed.
4315 (Limitations of Builtins): Explain better why the ! command isn't
4316 portable.
4318 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4320 * lib/autom4te.in (Automake-preselections): Preselect
4321 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4323 2004-05-19 Kevin Ryde <user42@zip.com.au>
4325 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4326 referencing AC_FUNC_STRERROR_R.
4328 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4329 note pessimistic assumption when cross compiling.
4331 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4333 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4334 (until 2004) invoked subcommands with sh -e, contra POSIX.
4335 Reported by Kevin Ryde.
4337 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4339 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4340 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4341 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4342 `test -f " /usr/bin/grep"', which _always_ failed.
4343 (AC_PROG_SED): Ditto bogus PATH fix.
4344 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4345 requires that grep correctly supports _multiple_ `-e' options, rather
4346 than stating only that grep should accept `-e'.
4348 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4350 Port to C99, which requires that 'exit' be declared.
4352 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4353 to ensure that stdlib.h is included.
4354 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4355 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4356 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4357 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4358 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4359 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4360 when using 'exit' in a test; C99 requires that 'exit' be declared.
4362 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4364 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4365 now prefers 'grep' implementations that accept -e.
4366 (Limitations of Usual Tools): Describe problems of traditional
4367 egrep and fgrep with long input lines, and of traditional grep
4368 with -e.
4369 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4370 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4371 All callers changed. Append /usr/xpg4/bin to the PATH, for
4372 Solaris.
4373 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4374 the user with complaints about multiple -e options.
4375 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4376 Define it with AC_PROG_GREP.
4377 * configure.ac (AC_PROG_GREP): Add.
4378 * lib/freeze.mk (GREP): New macro.
4380 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4382 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4383 a possible candidate only after all others fail, rather than
4384 consulting it first. This improves backward compatibility by
4385 better reflecting the way shell selection occurred in previous
4386 versions of Autoconf, and should help to avoid triggering latent
4387 problems in other packages, such as the one in Automake where zsh
4388 is not handled robustly:
4389 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4390 Although it is not Autoconf's responsibility to work around
4391 problems in Automake, it nevertheless makes sense to avoid
4392 introducing unnecessary incompatibilites.
4394 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4395 Gary V. Vaughan <gary@gnu.org>
4397 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4398 how deeply nested we are when a suitable tool is found, set the
4399 ac_path_TOOL_found flag.
4400 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4401 nested we are in this macro. Break out of all 3 nested loops if
4402 ac_path_TOOL_found is set.
4404 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4406 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4407 of the _AS_PATH_WALK loop too if GNU flavor is found.
4409 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4411 * doc/autoconf.texi (Limitations of Make): Update documentation
4412 for `$<'. New entry `Long lines', based on a report from Simon
4413 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4414 paragraph about DJGPP, based on a mail from Richard Dawe.
4416 2004-04-20 Paul Eggert <eggert@twinsun.com>
4418 * tests/c.at (C keywords): Don't assume that GCC supports
4419 "restrict" and "inline", as sufficiently-old GCC versions do not
4420 (also, GCC configured to be in pedantic C89 mode does not).
4421 Problem reported by Sumit Pandya in:
4422 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4424 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4425 consider -g to work if it generates warnings when plain compiles
4426 don't. Problem reported by Braden McDaniel in:
4427 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4429 * doc/autoconf.texi (Slashes): New section, to document a problem
4430 reported by Jim Meyering in:
4431 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
4433 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
4434 linker output files before linking, to work around IRIX 6 linker bug.
4435 Problem reported by Rainer Orth in:
4436 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
4438 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4440 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4441 best tool so far counter rely on the tool path variable name to
4442 avoid checks for one tool being affected by the results of running
4443 the length check on a previous tool.
4445 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4446 match expression argument, as different greps have different
4447 regular expression flavours.
4448 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4449 literals.
4450 (AC_PROG_EGREP): Pass 'EGREP$'.
4451 (AC_PROG_GREP): Pass 'GREP$'.
4453 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
4455 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
4456 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
4458 2004-03-29 Paul Eggert <eggert@twinsun.com>
4460 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
4461 Types, Specific Compiler Characteristics, System Services,
4462 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4463 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4464 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4465 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
4466 Likewise.
4467 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
4468 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
4469 AC_TYPE_OFF_T): Likewise.
4470 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
4471 Likewise.
4473 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
4474 pacify libtool 1.5.2. Fix quoting problems in sed command.
4476 2004-03-28 Paul Eggert <eggert@twinsun.com>
4478 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
4479 now defines HAVE_DECL_TZNAME if it is declared, when
4480 HAVE_STRUCT_TM_TM_ZONE is not defined.
4481 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
4482 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
4483 for HAVE_TZNAME.
4485 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
4487 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
4488 superfluous backslashing of quotes (") in sed expressions;
4489 thanks to Paul Eggert.
4491 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
4493 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
4494 Fortran compiler is ifort, also added pghpf; thanks to Nelson
4495 H. F. Beebe for the bug report.
4497 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
4499 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
4500 quoted -cmdline argument in Portland Group compiler (bug
4501 reported by Jeffrey J. Barteet).
4503 2004-03-25 Kevin Ryde <user42@zip.com.au>
4505 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
4506 (Run Time): ... here, where it's now mentioned.
4508 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
4510 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
4511 inherits from language Autoconf-without-aclocal-m4.
4512 (Customizing autom4te): Adjust example; the cache must now be
4513 disabled for language Autoconf-without-aclocal-m4.
4515 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
4516 Nathanael Nerode <neroden@twcny.rr.com>
4518 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
4519 AC_CHECK_TOOLS): Warn if a cross-tool is found without
4520 a prefix.
4521 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
4522 AC_CHECK_TARGET_TOOLS): New macros.
4523 * doc/autoconf.texi (Generic Programs): Document
4524 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
4525 AC_CHECK_TARGET_TOOLS, and warn for future changes
4526 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
4527 AC_CHECK_TOOLS.
4528 (Specifying Names): Document the reason for these future
4529 behavioral changes.
4530 * tests/mktests.sh: Do not generate tests for the
4531 new macros.
4532 * NEWS: Document these changes.
4534 * doc/autoconf.texi: Avoid macros with unbraced arguments,
4535 they make TeX hang up.
4537 2004-03-15 Paul Eggert <eggert@bogus.example.com>
4539 * NEWS: New macro AC_CHECK_ALIGNOF.
4540 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
4541 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
4542 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
4543 vowel.
4544 (AC_CHECK_ALIGNOF): New macro.
4545 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
4546 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
4547 those for sizeof.
4549 2004-03-03 Paul Eggert <eggert@twinsun.com>
4551 * bin/Makefile.am (edit): Don't use $< in a context where
4552 POSIX doesn't require support for it. Use $@.in instead.
4553 Problem reported by Anthony N. Frasso in
4554 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
4555 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
4557 2004-02-23 Gary V. Vaughan <gary@gnu.org>
4559 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
4560 from the next generation of Libtool.
4561 * lib/autom4te.in (Autoreconf-preselections): Ditto.
4563 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
4565 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
4566 is not always thread-safe. Report from Nathanael Nerode.
4568 2004-02-18 Paul Eggert <eggert@twinsun.com>
4570 Fix a dependencies problem, stemming from a Autoconf 2.59 build
4571 problem on QNX reported by Stephen Rasku in
4572 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
4574 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
4575 $(m4sh_m4f_dependencies); this removes a FIXME.
4576 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
4577 (MAINTAINERCLEANFILES): Split into pieces,
4578 one per related section. Add $(srcdir)/wrapper.in.
4580 2004-02-09 Paul Eggert <eggert@twinsun.com>
4582 * doc/autoconf.texi (Setting Output Variables): Emphasize that
4583 AC_SUBST provides no portable way to escape literal newlines.
4585 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4586 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4587 Darwin uses -lcrt2.o and there's little point to cataloging all
4588 the system variants. Partial fix reported by Andreas Waechter in:
4589 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
4590 for bug reported by Nelson H. F. Beebe in:

4593 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
4595 * doc/autoconf.texi (AU_DEFUN): Fix English,
4596 suggested by Paul Eggert.
4597 * lib/autoconf/autoupdate.m4: Correct reference to
4598 acobsolete.m4, suggested by Alexandre Duret-Lutz.
4600 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
4602 * bin/autoupdate.in: Define __file__ so that warnings
4603 refer to the correct file.
4604 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
4605 the behavior of the third argument.
4606 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
4607 correctly the behavior of the third argument. Document
4608 what the three macros that AU_DEFUN defines do. Fix
4609 warning message when the third argument includes $0
4610 (reported by Alexandre Duret-Lutz).
4612 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4613 Eric Sunshine <sunshine@sunshineco.com>
4614 Paul Eggert <eggert@twinsun.com>
4616 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
4617 (AS_INIT): Output shell initialization there. Removed optional
4618 parameter. Expand _AS_SHELL_FN_SPY.
4619 (AS_INIT_WITH_SHELL_FN): Removed.
4620 (_AS_SHELL_FN_SPY): New macro.
4621 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
4622 macros.
4623 (AS_SHELL_SANITIZE): Remove loop to find better shell
4624 and documentation for the parameter.
4625 (_AS_DETECT_BETTER_SHELL): Move it here.
4626 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
4627 (_AS_RUN): Move it here, support testing with eval.
4628 (AS_REQUIRE_SHELL_FN): Require shell functions when
4629 it is used.
4630 (_AS_LINENO_WORKS): Put around braces, we do not
4631 trigger the bash bug anymore.
4632 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
4633 use AS_INIT_WITH_SHELL_FN.
4634 * bin/autoconf.in, tests/wrapper.in: Regenerated.
4636 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4638 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
4639 * doc/autoconf.texi: Don't say that the third parameter
4640 is broken.
4641 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
4642 (AU_DEFUN): Honor the third parameter, create autoupdate
4643 macros with AU_DEFINE.
4644 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
4645 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
4646 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
4647 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
4648 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,
4649 AC_ARG_ARRAY, AC_CYGWIN, AC_EMXOS2, AC_MINGW32,
4650 AC_XENIX_DIR): Likewise.
4651 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS,
4652 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
4653 * lib/autoconf/status.m4: Remove FIXME.
4654 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
4655 that the macro is not present anymore in the updated
4656 configure.ac.
4657 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
4658 of autoupdate.
4660 2004-01-28 Paul Eggert <eggert@twinsun.com>
4662 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
4663 copyright years.
4664 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
4665 2003 (except 1997) to the list of copyright years. This undoes
4666 the 2003-05-22 change, which removed the older years from the list.
4667 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
4669 2004-01-27 Gary V. Vaughan <gary@gnu.org>
4670 Albert Chin-A-Young <china@thewrittenword.com>
4672 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
4673 grep or ggrep program in PATH that accepts as long lines as
4674 possible.
4675 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
4676 AC_PROG_GREP.
4677 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
4678 egrep and fgrep respectively if $GREP -E/-F don't work.
4679 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
4680 _AC_PROG_GREP, and AC_PROG_SED.
4681 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
4682 longest input length accepted by a command.
4683 (AC_PROG_SED): Use it.
4684 * doc/autoconf.texi (Particular Programs): Document the changes.
4685 * NEWS: Updated.
4687 2004-01-27 Paul Eggert <eggert@twinsun.com>
4689 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
4690 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
4691 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
4692 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
4694 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
4695 bin/autoconf.in, config/Makefile.in, config/config.guess,
4696 config/config.sub, config/install-sh, config/mdate-sh,

4707 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
4708 tests/actypes.at: Regenerate and/or sync with original
4709 sources.
4711 2004-01-26 Paul Eggert <eggert@twinsun.com>
4713 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4714 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4715 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4716 not <inttypes.h>. Problem reported by Tim Mooney in
4717 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
4718 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4719 Likewise.
4721 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4722 otherwise "make check" fails because it forbids cmp (I guess
4723 because cmp treats files as binary on DOS-like systems).
4725 * tests/mktests.sh: Update copyright date to 2004, since some tests
4726 have changed in 2004.
4728 2004-01-23 Gary V. Vaughan <gary@gnu.org>
4730 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
4731 non-truncating sed or gsed program in PATH.
4732 * tests/acprograms.at: Add it.
4733 * doc/autoconf.texi (Particular Programs): Document it.
4734 * NEWS: Updated.
4736 2004-01-15 Paul Eggert <eggert@twinsun.com>
4738 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4739 -std1 disables some useful extensions on Tru64. Problem reported
4740 by N. Lichtmaier in
4741 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
4743 2004-01-14 Paul Eggert <eggert@twinsun.com>
4745 * doc/autoconf.texi (Programming in M4sh): Document that
4746 AS_MKDIR_P succeeds if the destination is a symbolic link
4747 to an existing directory.
4748 (Limitations of Usual Tools): Note that mkdir -p might not
4749 succeed on symlinks to directories.
4751 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
4753 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
4754 * bin/autoheader.in: Grammar fix in message.
4755 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
4756 Test for dir before calling mkdir -p. (trivial changes)
4758 2004-01-13 Eric Blake <ebb9@byu.net>
4760 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
4761 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
4763 2004-01-10 Jim Meyering <jim@meyering.net>
4765 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
4767 2004-01-09 Paul Eggert <eggert@twinsun.com>
4769 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4770 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4771 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4772 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4773 AC_COMPILE_IFELSE, since we now assume our caller invokes
4774 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4775 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4776 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4777 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4779 2004-01-07 Paul Eggert <eggert@twinsun.com>
4781 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4782 `"'...'"`, as it's confusing (and I suspect it may not work on
4783 some platforms). The code was incorrect anyway, as it assumed
4784 that \$ evaluated to itself in that context. Reported by
4785 Alexandre Duret-Lutz.
4787 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
4789 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
4790 and _LT_AC_TAGCONFIG.
4792 2004-01-06 Paul Eggert <eggert@twinsun.com>
4794 * doc/autoconf.texi (One Macro Call): Fix an incorrect
4795 example, and add more examples. Reported by Eric Sunshine.
4797 2004-01-05 Paul Eggert <eggert@twinsun.com>
4799 * doc/autoconf.texi (Limitations of Usual Tools):
4800 Remove warning against "rm -fr" introduced yesterday; it
4801 was a false alarm.
4803 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
4804 autoscan, autoupdate, ifnames): Don't use chmod -w.
4805 * lib/Makefile.am (autom4te.cfg): Likewise.
4806 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
4807 "chmod -w".
4809 2004-01-04 Paul Eggert <eggert@twinsun.com>
4810 Paolo Bonzini <bonzini@gnu.org>
4812 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
4813 by doing lineno substitution only on lines containing "$LINENO".
4815 2004-01-04 Paul Eggert <eggert@twinsun.com>
4817 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
4818 Use "rm -f" to remove conftest.sed, not plain "rm".
4819 Bug reported by David Relson in
4820 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
4822 * Makefile.am (autom4te-update):
4823 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
4824 * Makefile.maint (my-distcheck, do-po-update): Likewise.
4825 * doc/autoconf.texi (Guidelines): Likewise.
4826 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

4831 * tests/Makefile.am (clean-local): Likewise.
4832 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
4833 srcdir): Likewise.
4834 * doc/autoconf.texi (Limitations of Usual Tools):
4835 Warn against "rm -fr".
4837 2004-01-03 Paul Eggert <eggert@twinsun.com>
4839 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
4840 -c -o might not work. From a suggestion by Kevin Ryde.
4841 (C Compiler, Generating Sources, Limitations
4842 of Usual Tools, Limitations of Make, Making testsuite Scripts):
4843 Don't put '-o' after non-options, as POSIX doesn't allow this.
4844 Mention that cc's name might be gcc or c89 or whatever.
4846 2004-01-04 Kevin Ryde <user42@zip.com.au>
4848 * doc/autoconf.texi: Add various further index entries.
4850 2003-12-29 Paul Eggert <eggert@twinsun.com>
4852 * bin/autoreconf.in (autoreconf_current_directory):
4853 Fix typo: mkdir without umask arg.
4855 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
4857 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
4858 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
4859 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
4860 explanation clearer.
4862 2003-12-24 Andreas Schwab <schwab@suse.de>
4864 * doc/autoconf.texi (Default Includes): Fix misspelling of
4865 AC_INCLUDES_DEFAULT.
4867 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
4869 * configure.ac: Test if sh -n works.
4870 * configure: Regenerate.
4871 * tests/atlocal.in: Store the result here.
4872 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
4873 tools.at, looking in atlocal's ac_cv_sh_n_works instead
4874 of explicitly testing.
4875 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
4876 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
4877 * tests/tools.at (Syntax of the shell scripts): Simplify
4878 using AT_CHECK_SHELL_SYNTAX.
4879 (Syntax of the Perl scripts): Remove definition of
4880 AT_CHECK_PERL_SYNTAX.
4882 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
4884 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
4885 stderr to /dev/null.
4886 * bin/autoconf.in: Regenerate.
4887 * bin/wrapper.in: Regenerate.
4889 2003-11-26 Paolo Bonzini <bonzini@gnu.org>
4891 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
4892 Extracted from AS_SHELL_SANITIZE.
4893 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
4894 macros.
4895 (AS_SHELL_SANITIZE): Move reinvocation code from
4896 _AS_LINENO_WORKS, use it to find out if shell
4897 functions work.
4898 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
4899 does not work.
4900 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
4901 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN
4902 was called.

4912 (&sizes): New.
4913 Use them.

4915 them on the fly.
4917 2003-11-24 Akim Demaille <akim@epita.fr>
4919 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

4947 parameter of AU_DEFUN.
4948 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.

4952 the expanded body, consistently with other macros such as AC_USG.
4954 2003-11-17 Paul Eggert <eggert@twinsun.com>
4956 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
4957 into the initial confdefs.h, to work around a bug in NextStep 3.3
4958 patch 3 reported by Eric Sunshine.
4960 2003-11-15 Kevin Ryde <user42@zip.com.au>
4962 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
4963 than $target since the latter is not usual, add guidelines on when to
4964 use or not use the system type.
4966 2003-11-12 Derek Price <derek@ximbiot.com>
4968 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
4969 typo misrepaired by an auto-spellcheck.
4971 2003-11-12 Akim Demaille <akim@epita.fr>

4977 2003-11-12 Akim Demaille <akim@epita.fr>

5121 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
5123 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
5124 cross test.
5126 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
5128 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
5129 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

5140 Issue a more-informative diagnostic.
5141 Problems reported by Eric Sunshine.
5143 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5145 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
5146 -mGLOB_options_string stuff for Intel ifc, which can cause

5156 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
5157 that future autopoint/aclocal/automake/autoreconf will be able

5166 -lcrt[01].o.
5168 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
5170 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
5171 cache variable instead of $G77 to decide whether to include -O2,
5172 since $G77 is specific to Fortran 77.
5174 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5176 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
5177 free" flag. Re-order flags tested into rough order of popularity.
5179 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5181 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
5182 arguments so that it can be used with syntax identical to
5183 AC_PROG_F77, and so that we can more easily decide to
5184 remove/deprecate the DIALECT optional argument in the future if it
5185 proves troublesome.
5186 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
5187 non-freeform-supporting compilers. Document freeform flags.
5189 2003-10-03 Akim Demaille <akim@epita.fr>
5191 * configure.ac: Look for emacs, not macs.
5192 Reported by Eric Sunshine.
5194 2003-10-03 Akim Demaille <akim@epita.fr>
5196 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
5197 * bin/autoreconf.in (autoreconf_current_directory): Create the

5199 Suggested by Alexandre Duret-Lutz.
5201 2003-10-03 Akim Demaille <akim@epita.fr>
5203 * configure.ac: Quotation and formatting changes.

5224 * lib/Autom4te/XFile.pm: Use Errno.
5225 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
5226 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
5228 2003-09-30 Akim Demaille <akim@epita.fr>
5230 * config/announce-gen (&print_news_deltas): Extracted from...
5231 (&print_changelog_deltas): here.
5232 (&news_file): Rename as...
5233 (@news_file): this.

5250 Problem reported by Lars J. Aas in
5251 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
5252 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
5253 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
5254 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
5256 2003-09-26 Akim Demaille <akim@epita.fr>
5258 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5259 directory for AC_CONFIG_COMMANDS' first argument exists.
5260 This makes valid the invocation of _AC_SRCPATH that follows.
5261 Reported by Eric Sunshine.
5262 * doc/autoconf.texi (Configuration Commands): Adjust.
5264 2003-09-26 Akim Demaille <akim@epita.fr>
5266 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
5267 Reported by Ralf Corsepius.
5269 2003-09-26 Akim Demaille <akim@epita.fr>
5271 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
5272 arguments.
5273 Actually, use AU_ALIAS.
5274 From Bruno Haible.
5276 2003-09-26 Paul Eggert <eggert@twinsun.com>
5278 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
5279 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
5280 Problem reported by Eric Sunshine in:

5283 2003-09-26 Akim Demaille <akim@epita.fr>
5285 The test suite are sometimes assigning timings incorrectly.
5286 Reported by Henk Krus.
5287 Diagnosed by Nicolas Joly.
5289 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5290 AT_help_all.
5291 Instead of making AT_help a sequence of assignments to grow
5292 $at_help_all, just make AT_help_all be the growing contents of
5293 $at_help_all, and make a single assignment in...
5294 (AT_INIT): here.
5295 (at_times_skip): Flip the meaning and rename as...
5296 (at_times_p): this.
5297 (AT_INIT): When summarizing the test that ran, remove
5298 $at_times_file after use, and check it is present before trying to
5299 use it.
5301 2003-09-25 Akim Demaille <akim@epita.fr>
5303 Version 2.57d.
5305 * bin/Makefile.am (edit): Handle '@configure_input@'.
5306 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
5307 (ifnames): chmod -w.
5308 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5309 executables, not bin/ executables! Otherwise all the magic needed
5310 to find non installed files is turned off. This caused a failure
5311 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5312 as found in its environment (sent by tests/autoreconf): pointing
5313 to bin/autom4te that could not find its files.
5314 * tests/mktests.sh: Force the replacement of generated files, for
5315 the sake of "mv" program that are interactive when overwriting a
5316 -w file.
5317 * config/install-sh: Upgrade from CVS Automake.
5319 2003-09-23 Paul Eggert <eggert@twinsun.com>
5321 * doc/autoconf.texi (Limitations of Builtins): Document test -h
5322 versus test -L issues.
5324 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
5325 Paul Eggert <eggert@twinsun.com>
5327 Trivial change to support GCC's configuration procedure.
5328 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
5329 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
5330 about inconsistency if the preprocessor is set to give errors for
5331 any warning.
5332 * doc/autoconf.texi (C Compiler Characteristics): Document this.
5334 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
5336 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
5337 and XFile.pm from Automake.

5350 2003-09-12 Akim Demaille <akim@epita.fr>
5352 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
5353 not asm/types.h.
5355 2003-09-11 Akim Demaille <akim@epita.fr>
5357 * doc/autoconf.texi (Header Portability): linux/random.h.
5358 From Peter Hendrickson.
5360 2003-09-10 Akim Demaille <akim@epita.fr>
5362 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
5363 willing to edit the output files.
5365 2003-09-10 Akim Demaille <akim@epita.fr>
5367 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
5368 and AC_FC_FREEFORM.
5369 * tests/mktests.sh: Skip AC_FC_SRCEXT.
5370 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
5372 2003-09-09 Akim Demaille <akim@epita.fr>

5385 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
5386 Improve the accuracy of the wording about obsolescence.
5387 From a suggestion by Ian Lance Taylor in
5388 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
5390 2003-09-05 Paul Eggert <eggert@twinsun.com>
5392 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
5393 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
5395 2003-09-04 Akim Demaille <akim@epita.fr>
5397 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
5398 AC_FUNC_WAIT3.
5400 2003-09-04 Akim Demaille <akim@epita.fr>
5402 * bin/autom4te.in: Use &fatal where more appropriate than &error.
5403 (freeze): When exiting, use $exit_code.
5404 * lib/autoconf/fortran.m4: Comment changes.
5406 2003-09-04 Akim Demaille <akim@epita.fr>
5408 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
5410 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
5412 Add support for newer Fortran dialects. The F77 interface is
5413 unchanged, and continues to support Fortran 77. New FC macros
5414 correspond to all the old F77 macros, with output variables FC,
5415 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5416 available dialect, but older dialects can be specified. There are
5417 new macros AC_FC_SRCEXT to set the source extension, and
5418 AC_FC_FREEFORM to accept free-form source files.
5420 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
5421 New macros.
5422 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

5438 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
5439 Rewrite in terms of the above.
5440 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
5441 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

5447 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
5448 Document problems with timestamp resolution that 'make', 'cp -p', and
5449 'touch -r' have.
5451 2003-08-27 Akim Demaille <akim@epita.fr>
5453 * tests/m4sugar.at (cross_warning): Make sure to enable the
5454 output, so that we can track spurious m4sugar output.
5455 * tests/local.at: Require 2.57.
5456 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5457 are defaulted by AT_CHECK anyway.
5458 Use AT_CHECK_AUTOM4TE.
5459 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
5460 missing dnl.
5462 2003-08-27 Akim Demaille <akim@epita.fr>
5464 * bin/autoheader.in: Issue the "Using auxiliary..." message only
5465 when -Wobsolete is set.
5466 Set it on by default.
5467 Suggested by Klee Dienes.
5469 2003-08-27 Akim Demaille <akim@epita.fr>
5471 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
5472 documentation.
5473 From Guido Draheim.
5475 2003-08-26 Akim Demaille <akim@epita.fr>

5478 after AC_OUTPUT.
5480 2003-08-25 Akim Demaille <akim@epita.fr>
5482 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
5483 CVS Bison.
5485 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
5487 * bin/autoreconf.in (parse_args): Do not pass --no-force to

5499 2003-08-22 Akim Demaille <akim@epita.fr>
5501 Version 2.57b.
5503 * Makefile.cfg (local-checks-to-skip): New.
5504 * Makefile.maint (local-check): Rename as...
5505 (local-checks-available): this.
5506 (local-check): New.
5508 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
5509 * configure.ac: Require Automake 1.7.6.
5511 2003-08-22 Akim Demaille <akim@epita.fr>
5513 Output stack traces in warnings.
5515 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
5516 Replace the former...
5517 (m4_warn): Pass the call stack to _m4_warn.
5518 * bin/autom4te.in: Adjust to output the call stack.
5519 * tests/m4sugar.at (m4@&t@_warn): Adjust.
5521 2003-08-22 Akim Demaille <akim@epita.fr>
5523 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
5524 * bin/autom4te.in: Adjust.
5526 2003-08-21 Akim Demaille <akim@epita.fr>
5528 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
5529 (&verbose): Remove.
5530 (&getopt): Adjust the note and verb channels, depending upon
5531 --verbose.
5532 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
5533 * bin/autoupdate.in: Adjust.
5534 Use &verb, not &verbose.
5536 2003-08-21 Akim Demaille <akim@epita.fr>
5538 * bin/autoheader.in (&parse_args): Use &parse_warnings and
5539 &parse_WARNINGS.
5540 ($help): Use Autom4te::ChannelDefs::usage.
5541 * bin/autoscan.in: Use Autom4te::ChannelDefs.
5542 * lib/Autom4te/General.pm: Don't export error: you don't own it.
5544 2003-08-21 Akim Demaille <akim@epita.fr>
5546 First stab at preserving warnings between calls to autom4te,
5547 including when the cache is used.
5549 There are still several issues: (i) there are too many runs of m4
5550 (one for include, one for warnings, and some more), (ii) warnings
5551 spreading on several lines are not handled gracefully, (iii) the
5552 code meant to have the call stack display for errors does not work
5553 (its handling should move from m4 to autom4te).
5555 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5556 Use them.
5557 (@preselect): Add m4_warn.
5558 ($exit_status): Remove, use $exit_code.
5559 ($help): Use Autom4te::ChannelDefs::usage.
5560 (&handle_m4): No longer define the m4_warnings.
5561 At each run, extract and report the warnings.
5562 Always cache the result, including if the exit status is on
5563 failure, since if nothing changes, we should result in the same
5564 failure, hence we can use the cache.
5565 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5566 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5567 Remove.
5568 (m4_warn): Redefine as a do-nothing: it is its invocation that
5569 matters, as warnings are now reported via traces.
5570 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5571 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5572 the latter reveals calls to the former.
5574 Adjust the tests.
5576 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
5578 2003-08-21 Akim Demaille <akim@epita.fr>
5580 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
5581 Use them.
5583 2003-08-21 Akim Demaille <akim@epita.fr>
5585 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
5586 forward order.
5587 * lib/Autom4te/ChannelDefs.pm: Doc typos.
5588 (&parse_warnings): Accept a list of warning requests.
5589 (&usage): Return a string, not a side effect.
5590 (cross): New warning category.
5592 2003-08-21 Akim Demaille <akim@epita.fr>
5594 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
5595 (&require_configure_ac): Accept an optional directory argument.
5596 ($configure_ac): Remove.
5597 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
5598 (&catfile): Remove.
5599 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
5600 * bin/autoscan.in: Adjust.
5602 2003-08-20 Akim Demaille <akim@epita.fr>
5604 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
5605 Reported by Alexandre Duret-Lutz.
5607 2003-08-20 Akim Demaille <akim@epita.fr>
5609 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
5610 * bin/autom4te: Adjust.
5611 In particular, be Autoconf tools are really silent when properly
5612 working, bind the verbosity of the 'note' channel to $verbose.
5613 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5614 (&xsystem, &contents): Remove, since they are exported by...
5615 * lib/Autom4te/FileUtils.pm: this.
5616 More perldoc.
5617 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
5618 * lib/Autom4te/FileUtils.pm: here.
5620 2003-08-20 Akim Demaille <akim@epita.fr>
5622 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
5623 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
5624 from CVS Automake.
5626 2003-08-20 Akim Demaille <akim@epita.fr>
5628 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
5629 (autom4te-update): New.
5630 * Makefile.cfg (update): Bind autom4te-update.
5632 2003-08-19 Derek Price <derek@ximbiot.com>
5634 * lib/autotest/general.m4: Comment various HELP_* diversions.
5635 (PARSE_ARGS_BEGIN): New section for option parsing related
5636 initialization.

5642 * config/announce-gen, Makefile.cfg: New.
5643 * Makefile.am: Adjust.
5644 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
5646 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
5648 * lib/autom4te.in (Automake-preselections): Preselect
5649 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
5650 and m4_sinclude.
5652 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
5654 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
5655 (Autoconf-without-aclocal-m4): ... this new language.
5656 * doc/autoconf.texi (autom4te Invocation): Mention
5657 Autoconf-without-aclocal-m4.

5661 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
5662 RUN-IF-PASS optional arguments.

5671 STDOUT & STDERR arguments.
5673 2003-08-14 Derek Price <derek@ximbiot.com>
5675 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
5676 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
5677 shorter column three. Add DESCRIPTION to log file content.
5679 2003-08-13 Derek Price <derek@ximbiot.com>
5681 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
5682 output.
5684 2003-08-12 Derek Price <derek@ximbiot.com>
5686 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
5687 (AT_CHECK_NOESCAPE): Move core functionality to...
5688 (_AT_CHECK): ...this new macro.
5690 2003-08-07 Derek Price <derek@ximbiot.com>
5692 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
5693 (AT_CHECK_NOESCAPE): ...to this new macro.
5695 2003-07-31 Paul Eggert <eggert@twinsun.com>
5697 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
5698 in Bash 2.01. Problem reported by Brian Gough in
5699 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
5701 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
5703 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
5704 -lcrt1.o, for OS X. (trivial change)
5706 2003-07-07 Paul Eggert <eggert@twinsun.com>
5708 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
5709 inside '#ifndef __cplusplus'. Problem reported by
5710 Bob Friesenhahn.
5712 2003-07-06 Bill Clarke <llib@computer.org>
5714 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
5715 'long', not 'int', for benefit of Sun's recent C++ compilers
5716 (trivial change). See:
5717 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
5718 (This really should be 'intptr_t', not 'long', but that would
5719 take more work.)
5721 2003-06-25 Akim Demaille <akim@epita.fr>
5723 * lib/Makefile.am (autom4te.cfg): Make it read only.
5724 Depend on Makefile since it contains substitutions.
5725 From Paolo Bonzini.
5726 * lib/autom4te.in (args): Add local.at? for Autotest args.
5727 This change was made on autom4te.cfg which is generated.
5728 Reported by Raja R. Harinath.
5730 2003-06-25 Akim Demaille <akim@epita.fr>
5732 * doc/autoconf.texi (Header Portability): sys/mount.h.
5733 From Gareth McCaughan.
5735 2003-06-23 Akim Demaille <akim@epita.fr>
5737 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5738 not all of them. This fixes 1. the fact that when testing
5739 Autoconf there are many many config.log, 2. the incorrect use of
5740 top_srcdir to find config.log.
5741 Don't mix the detailed output of failed test with the summary of
5742 failures. Rather, append detailed log afterwards.
5744 2003-06-23 Akim Demaille <akim@epita.fr>
5746 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
5747 always run: output config.log on $at_group_log.
5749 2003-06-23 Akim Demaille <akim@epita.fr>
5751 * tests/torture.at (#define header templates): Don't use quotes in
5752 C++ comments as it puzzles Emacs' sh font-lock-mode.
5754 2003-06-23 Akim Demaille <akim@epita.fr>
5756 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
5757 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
5758 * tests/atspecific.m4: Rename as...

5761 * tests/local.at: here.
5762 * tests/Makefile.am: Adjust.
5763 * doc/autoconf.texi (testsuite Scripts): Adjust.
5765 2003-06-21 Kevin Ryde <user42@zip.com.au>
5767 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
5768 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
5769 ensuring we add -std1 for full-ANSI.
5771 * doc/autoconf.texi (hdrindex): New macro.
5772 Add index entries for portability of various standard header files.
5774 2003-06-20 Akim Demaille <akim@epita.fr>
5776 * configure.ac: Bump to 2.57b.
5778 2003-06-20 Akim Demaille <akim@epita.fr>
5780 Version 2.57a.
5782 2003-06-20 Akim Demaille <akim@epita.fr>
5784 * bin/autom4te.in: Don't rely on $HOME being defined.
5785 Reported by Marc Espie as PR/233.
5787 2003-06-20 Akim Demaille <akim@epita.fr>
5789 * lib/autotest/general.m4: Use at_times_file only if used.
5790 From Nicolas Joly.
5792 2003-06-20 Akim Demaille <akim@epita.fr>
5794 * config/config.guess, config/config.sub, config/elisp-comp,
5795 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
5796 Update from masters.
5798 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
5800 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
5801 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
5802 (TEST_SCRIPT): New diversion.
5803 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
5804 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
5805 (AT_INIT): Support for expected failures.
5807 2003-06-02 Akim Demaille <akim@epita.fr>
5809 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
5810 changes.
5811 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
5812 Autoconf nor Automake.
5813 (&contents): New, from Automake.
5814 PODify.
5816 2003-05-28 Paul Eggert <eggert@twinsun.com>
5818 * NEWS, doc/autoconf.texi (Particular Functions),
5819 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
5820 is the inverse of localtime.
5822 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
5824 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
5825 (handle_exec_errors): New function. Work around $! being
5826 altered by WEXITSTATUS.
5827 (xqx, xsystem): Use handle_exec_errors.
5829 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
5831 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
5832 Do not call `_exit()', simply modify `$?'.
5833 (xsystem): Reset $! before running system, and check it afterward.
5834 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
5835 63 for version mismatches.
5837 2003-05-23 Akim Demaille <akim@epita.fr>
5839 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
5840 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
5841 the middle of a line).
5842 * lib/m4sugar/m4sugar.m4: Likewise.
5843 Remove useless spaces in comments.
5845 2003-05-23 Akim Demaille <akim@epita.fr>
5847 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
5848 exit 63, so that we (or Automake's "missing") can tell the
5849 difference with a plain failure.
5850 * doc/autoconf.texi (Notices): Adjust.
5852 2003-05-23 Akim Demaille <akim@epita.fr>
5854 * Makefile.am, bin/Makefile.am, config/Makefile.am,
5855 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
5856 White spaces cleanup.
5858 2003-05-22 Jim Meyering <jim@meyering.net>
5859 Paul Eggert <eggert@twinsun.com>
5861 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
5862 Remove `#include <stdlib.h>' from the list; we should never
5863 make confdefs.h include <stdlib.h> or <cstdlib>, because the
5864 resulting namespace pollution would cause other tests to fail.
5865 Configure scripts run with some older versions of g++ and HP's
5866 aCC would fail due to such an #include. Problems reported by
5867 Matthew Mueller in <http://bugs.debian.org/120704> and by
5868 Keith Bostic in
5869 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
5870 In the test, use the test declaration before including <stdlib.h>,
5871 as that's closer to how it'll be used.
5873 2003-05-23 Akim Demaille <akim@epita.fr>
5875 * doc/autoconf.texi (Header Portability): ucred.h.
5876 From Ian Redfern.
5878 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5880 Overhaul Autotest's logging: generate separate log files
5881 in testsuite.dir/NNN/testsuite.log, and append them to
5882 testsuite.log instead of re-running the test verbosely.
5884 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
5885 file descriptor, write 0 to at_status_file instead of setting
5886 at_status=0, initialize some new variables (at_status_file,
5887 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
5888 to rerun the tests, instead append the at_group_log to the
5889 at_suite_log when a test fails.
5890 (AT_SETUP): pipe the test case's output into at_tee_pipe,
5891 with the AS_MESSAGE_LOG_FD redirected to stdout.
5892 (AT_CLEANUP): save the output status in $at_status_file
5893 and restore it, redirect the AS_MESSAGE_LOG_FD back to
5894 its original place.
5895 (AT_CHECK): since tests are run with a redirected stdout,
5896 and used to be re-run in verbose mode, turn some $at_verbose
5897 into echo, and don't redirect the output of testing stdout
5898 and stderr.
5900 * lib/autotest/autoconf.texi (testsuite Scripts): Update
5901 the name of the debugging directory and information about
5902 its contents.
5904 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5906 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
5907 parameter.

6019 and truncate.
6021 2003-05-06 Akim Demaille <akim@epita.fr>
6023 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6024 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6025 by aclocal.m4 is changed it might require the importing of another
6026 m4 extension file, i.e., aclocal must be run.
6028 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6029 (&parse_args): Use --force with aclocal if required and supported.
6030 (&autoreconf_current_directory): Use &run_aclocal.

6037 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
6038 argument instead of a file name, so that the request file remains
6039 open during the whole autom4te run.
6040 ($icache_file): New.
6041 (&freeze): Lock the $icache_file.
6043 2003-04-29 Derek Price <derek@ximbiot.com>
6045 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
6046 seperator with m4_append_uniq(). It doesn't work.
6047 (AT_CLEANUP): Add `;' to end of at_help_all.
6048 (AT_INIT): Allow --keywords to be specified more than once. When
6049 grepping $at_help_all for keywords, use the field and keyword
6050 seperators to ensure a complete keyword match. Alter at_prev handling
6051 to support the new --keywords behavior.
6053 2003-04-27 Karl Berry <karl@freefriends.org>
6055 * doc/autoconf.texi: Make the dir entries in the autoconf manual
6056 align better with others. I also made some of the individual
6057 entries on one line, for brevity and to make it easier for me to
6058 sort my dir-example file in the Texinfo distribution :).
6060 2003-04-12 Jim Meyering <jim@meyering.net>

6125 header causes problems.
6127 2003-03-28 Akim Demaille <akim@epita.fr>
6129 * tests/torture.at (Configuring subdirectories): Require aclocal
6130 1.4, otherwise the test fails, as it does support configure.ac.
6131 This fixes the "test 40 failed" bug reports.

6135 * doc/autoconf.texi (C Compiler): `#line' portability.

6141 layout in order to allow scripting around test groups.
6143 2003-03-27 Derek Price <derek@ximbiot.com>
6145 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
6146 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
6147 use new diversions in preparation for accepting new arguments and

6155 (AC_HELP_STRING): AU_DEFUN to...
6156 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
6157 * tests/m4sh.at (AS_HELP_STRING): New test.
6159 * tests/acgeneral.at: Regenerated.
6161 2003-03-26 Derek Price <derek@ximbiot.com>
6163 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
6164 sense. Verbosify the diversion definitions comment.
6166 2003-03-26 Derek Price <derek@ximbiot.com>
6168 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to

6200 * doc/autoconf.texi (Limitations of Make): Remove the section
6201 about `$<' in inference rules, it was a bogus interpretation of
6202 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
6203 Tru64 make in the "target lookup" section.
6204 (Automake): Automake 1.5+ no longer requires special tools to be
6205 present on the developer's host.

6212 Use of $^O suggested by Tim van Holder.
6213 * bin/autom4te.in (BEGIN): Likewise.
6214 * bin/autoreconf.in (BEGIN): Likewise.
6215 * bin/autoscan.in (BEGIN): Likewise.
6216 * bin/autoupdate.in (BEGIN): Likewise.

6219 * bin/ifnames.in: Add final newline to help and version messages.
6221 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
6222 to cope with DOS-style absolute paths, when constructing
6223 ${ac_make}.
6225 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
6226 When constructing paths with IFS=:, quote the path. If we're
6227 constructing a DOS-style absolute path, we don't want to split it
6228 on the colon.
6230 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
6231 in description.
6233 2003-02-25 Pavel Roskin <proski@gnu.org>

6241 2002-09-01 patch by replacing "test -n" with "test -z".
6242 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
6243 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
6245 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
6246 to fix a mismatch between example and discussion.
6248 2003-02-24 Kevin Ryde <user42@zip.com.au>
6250 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
6251 format starting with "-".
6253 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6255 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
6256 is not portable inside Makefile.
6258 2003-02-20 Akim Demaille <akim@epita.fr>
6260 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
6261 compiler says yeah, but preproc says nope, compiler is right.
6262 Conversely, prompt the reader to send a bug report to the
6263 maintainers of the package, not of Autoconf.
6265 2003-02-20 Klee Dienes <kdienes@apple.com>
6267 * bin/autoreconf.in (autoreconf_current_directory): Properly
6268 handle an empty aclocal.m4.

6272 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Quote
6273 $ac_prefix_program.
6274 From Larry Jones.
6276 2002-12-23 Paul Eggert <eggert@twinsun.com>
6278 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
6279 innocuous variant befor including <limits.h> or <assert.h>. This
6280 works around a bug reported by Albert Chin: HP-UX 11i
6281 (and earlier versions) have a <limits.h> that declares
6282 gettimeofday and many other functions.
6284 2002-12-03 Paul Eggert <eggert@twinsun.com>
6286 Version 2.57.
6288 * NEWS, configure.ac: Update version.
6290 * doc/fdl.texi: Upgrade to FDL version 1.2.
6292 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6293 nontrivially in main's body, so that f's external declaration is
6294 not optimized away in AIX. This should fix the bug reported by
6295 Martin Frydl in
6296 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
6298 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
6299 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6300 defined, to support freestanding compilers. This should fix the
6301 bug reported by Momchil Velkov in
6302 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6304 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
6305 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
6306 obsolete AC_CHECK_TYPE. The missing empty arg was reported
6307 by Simon Josefsson in
6308 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
6310 * Makefile.maint (www-gnu): New macro.
6311 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
6312 the location has moved.
6314 2002-12-02 Martin Frydl <martin@systinet.com>
6316 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
6317 \(.*\) match is too long and there is something more to be checked.
6318 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
6320 2002-11-15 Akim Demaille <akim@epita.fr>
6322 Version 2.56.
6324 * config/install-sh: chmod +x.
6325 From Paul Eggert.
6326 * config/move-if-change: Indenting changes.
6327 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
6328 * configure.ac (AM_INIT_AUTOMAKE): here.
6329 Require 1.7.1.
6331 2002-11-14 Akim Demaille <akim@epita.fr>
6333 Version 2.55.
6335 * config/config.guess, config/config.sub, config/install-sh:
6336 Update from masters.
6338 2002-11-14 Akim Demaille <akim@epita.fr>
6340 * Makefile.maint: Sync with Bison, i.e.:
6341 (po-check): Scan .l and .y files instead of the
6342 .c and the .h files that they generate. This fixes the bug
6343 reported by Tim Van Holder in:
6344 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6345 Look for N_ as well as for _. Try to avoid matching #define for
6346 N_ and _.
6347 From Paul Eggert.
6349 2002-11-14 Akim Demaille <akim@epita.fr>
6351 * doc/autoconf.texi (C Compiler): Compiling several files at once.
6352 From Paul Eggert and Albert Chin-A-Young.
6354 2002-11-14 Akim Demaille <akim@epita.fr>
6356 * doc/autoconf.texi (C Compiler): Solitary backslashes.
6357 From Paul Eggert and Albert Chin-A-Young.
6359 2002-11-14 Kevin Ryde <user42@zip.com.au>
6361 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
6362 than assigning in main, to avoid HP cc +O3 optimizing it away.
6364 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
6366 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
6367 option. Process --recheck after parsing all options. Pass -q
6368 option to configure on --recheck.
6369 (AC_OUTPUT): Pass -q from configure to config.status.
6370 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
6371 arguments to record.
6372 * doc/autoconf.texi (config.status Invocation): Document
6373 config.status -q option.
6375 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
6377 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
6378 Makefile.in if Makefile.am exists.
6379 (output): Strip `.am' from Makefiles. Don't
6380 output AC_CONFIG_FILES if no Makefiles were found.
6382 2002-11-07 Akim Demaille <akim@epita.fr>
6384 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
6385 (local_updates): New.
6386 * Makefile.maint: Update, from CVS Bison.
6387 (local_updates): New.
6389 2002-11-06 Akim Demaille <akim@epita.fr>
6391 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
6392 declaration in extern "C" too.
6393 Reported by Roberto Bagnara.
6395 2002-11-06 Akim Demaille <akim@epita.fr>
6397 * tests/torture.at (Configuring subdirectories): Don't use grep
6398 -w.
6399 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
6400 Reported by Ezra Peisach.
6402 2002-11-05 Akim Demaille <akim@epita.fr>
6404 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6405 Remove.
6406 We _have_ to stop using the old compatibility scheme that tried to
6407 avoid useless backslashes because Libtool 1.4.3 contains a
6408 AC_DEFINE([error_t], [int],
6409 [Define to a type to use for \`error_t' if it is not
6410 otherwise available.])
6411 We _have_ to quote the single quote and backslashes with \. The
6412 old compatibility scheme saw that ` was backslashed, and therefore
6413 did not quote the single quote. Hence before this patch, Autoconf
6414 was not compatible with Libtool.
6416 2002-11-04 Paul Eggert <eggert@twinsun.com>
6418 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
6419 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
6420 LC_NAME, LC_PAPER, LC_TELEPHONE.
6421 * doc/autoconf.texi (Special Shell Variables): Mention those vars.
6423 2002-11-04 Akim Demaille <akim@epita.fr>
6425 Version 2.54c.
6427 * Makefile.maint (update, cvs-update, po-update, do-po-update):
6428 New.
6429 * config/texinfo.tex: Update.
6431 2002-11-03 Akim Demaille <akim@epita.fr>
6433 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
6434 from...
6435 (&autoreconf): here.
6436 ($help, $make, &parse_args, &autoreconf_current_directory):

6512 * tests/torture.at (Deep Package): New test.

6746 2002-10-22 Akim Demaille <akim@epita.fr>
6748 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

6752 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
6753 strings.
6755 2002-10-22 Akim Demaille <akim@epita.fr>
6757 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

6804 longer required can still cause errors.
6805 Reported by Alexandre Duret-Lutz.
6807 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
6808 to frozen files in @ARGV, as @ARGV must remain being a list of

6810 (&files_to_options): New function.
6811 (&freeze): Use &error.
6812 (&up_to_date): If a file that was included according to the cache
6813 is no longer there, then the output is out dated.
6814 (&main): Don't even check whether a file is up to date is anyway
6815 --force is given.
6816 * tests/tools.at (autom4te cache): New.
6818 2002-10-16 Akim Demaille <akim@epita.fr>

6823 Factor some code.
6824 (&autoreconf): Report the directories we enter *and leave*, so
6825 that error messages can be easily located, and use GNU Make
6826 format, so that Emacs' compile mode understands us.
6827 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
6828 if some file was changed instead of `print'.
6829 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

6863 file name to enable parallel executions.
6864 From Sam Varshavchik.
6866 2002-10-08 Akim Demaille <akim@epita.fr>
6868 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
6869 aclocal invocation, as Gettext macros might not be visible to
6870 aclocal.
6871 Instead of blindly running autopoint, scan configure.ac (not the
6872 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
6873 Reported by Paul D. Smith.
6875 2002-10-08 Paul Eggert <eggert@twinsun.com>
6877 Work around problems found when POSIXLY_CORRECT=1 is set.
6878 None of this seems to have anything to do with POSIX, really,
6879 but it's how Perl getopt works.
6880 * bin/autom4te.in (parse_args): Configure GetOpt with
6881 "permute", too.
6882 * doc/autoconf.texi (Invoking autom4te):
6883 --warning -> --warnings.

6903 2002-09-28 Akim Demaille <akim@epita.fr>
6905 * tests/torture.at (Configuring subdirectories): Be robust to
6906 users who use config.site to require for a cache: in this case,
6907 the two last configure runs, using two different sets of
6908 arguments, trigger a legitimate error.
6910 2002-09-28 Akim Demaille <akim@epita.fr>

6926 (tm_zone): Move their rules to...
6927 * lib/autoconf/types.m4: here, using AN_ macros.
6928 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
6929 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)

6938 * lib/autoconf/autoscan.m4: New file.
6939 * lib/autoconf/autoconf.m4: Include it.

6943 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
6944 (.m4.m4f): Don't pass --prepend-include, since that's done by
6945 tests/autom4te itself.
6946 * lib/autoscan/Makefile.am: Include freeze.mk.
6947 (autoscan.list): New target --this file is no longer a source.
6948 (autoscan.pre): New file.
6950 2002-09-28 Akim Demaille <akim@epita.fr>
6952 * bin/autoscan.in (@kinds): Make them singular.
6953 Adjust all uses.
6954 (&init_tables): When --debug, report the list of rules to ease
6955 tracking changes in autoscan.list.
6956 * lib/autoscan/autoscan.list (function): Strip comments, sort.
6958 2002-09-28 Akim Demaille <akim@epita.fr>
6960 * lib/autoscan/functions, lib/autoscan/headers,

6964 * bin/autoscan.in (&init_tables): Adjust.
6966 2002-09-28 Akim Demaille <akim@epita.fr>
6968 * lib/autoscan/functions, lib/autoscan/headers,
6969 * lib/autoscan/identifiers, lib/autoscan/makevars,
6970 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
6971 `functions' line is now prefixed with `function:'.
6972 * bin/autoscan.in (&init_tables): Adjust.
6974 2002-09-28 Akim Demaille <akim@epita.fr>
6976 From now on, autoscan files must always map a macro name to a
6977 word: there is no `default' macro for autoscan.
6979 * bin/autoscan.in (&init_tables): Reject entries with no macro at
6980 all.
6981 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
6982 explicit.
6984 2002-09-28 Akim Demaille <akim@epita.fr>
6986 * bin/autoscan.in (%c_keywords): Remove.
6987 (&used): Keep only track of the words we might be interested in.
6988 (&output_kind): It is no longer needed to look for non active
6989 checks.

6998 2002-09-27 Akim Demaille <akim@epita.fr>
7000 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
7001 from /tmp.
7002 Thanks to Bill Moseley and Paul Eggert.
7003 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
7004 the tmpdir must be created.
7005 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
7006 dir be in the build tree, instead of $TMPDIR.
7008 2002-09-27 Akim Demaille <akim@epita.fr>
7010 * bin/autoscan.in: Improve the comments.
7011 (&parse_args): Drop obsolete undocumented options.
7012 (&output_kind): Output warnings.
7013 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

7019 Reported by Ralf Corsepius.
7020 * doc/autoconf.texi (autoreconf Invocation): Likewise.
7022 2002-09-26 Akim Demaille <akim@epita.fr>
7024 Single suffix rules and seperated dependencies are not portable.
7026 * doc/autoconf.texi (Installation Directory Variables): Update.
7027 (Limitations of Make): Some about `Single Suffix Rules and
7028 Separated Dependencies'.
7029 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7030 (ifnames, autoscan, autom4te): Un-factor into several rules.
7032 2002-09-25 Paul Eggert <eggert@twinsun.com>
7034 * BUGS (Interoperability bugs): New section. Mention libtool
7035 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
7037 2002-09-24 Paul Eggert <eggert@twinsun.com>
7039 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
7040 make handles suffix-rules differently from GNU make.
7042 * bin/Makefile.am (SUFFIXES, .in): Remove.
7043 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
7044 Move the body of the old .in rule here.
7046 2002-09-16 Akim Demaille <akim@epita.fr>
7048 i960 compilers create `b.out' files by default.
7049 Reported by Ralf Corsepius.
7051 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
7052 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
7054 2002-09-13 Paul Eggert <eggert@twinsun.com>
7056 * doc/autoconf.texi (Particular Headers): Remove obsolete
7057 reference to `struct timezone' in the description of
7058 AC_HEADER_TIME.
7060 2002-09-13 Akim Demaille <akim@epita.fr>
7062 Version 2.54.
7064 * config/config.sub, config/config.guess: Update.
7065 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
7066 * Makefile.am: Adjust.
7068 2002-09-13 Akim Demaille <akim@epita.fr>
7070 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
7071 reading config.log when the compiler is rejected.
7072 Suggested by Guido Draheim.
7074 2002-09-13 Akim Demaille <akim@epita.fr>
7076 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
7077 (chdir_init) might hang when stat'ing mounted directories.
7078 Reported by Vance Shipley.
7080 2002-09-12 Akim Demaille <akim@epita.fr>
7082 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
7083 the lists.
7085 2002-09-12 Akim Demaille <akim@epita.fr>
7087 * doc/autoconf.texi (Defining Symbols): Present two different
7088 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
7089 difference between 1 argument calls, and 2-3 argument calls.
7091 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
7093 * doc/autoconf.texi: Review grammar and punctuation.
7095 2002-09-11 Paul Eggert <eggert@twinsun.com>
7097 * doc/autoconf.texi: Fix minor formatting, spelling, and
7098 grammatical typos.
7099 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
7100 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
7101 is obsolescent.
7103 2002-09-11 Akim Demaille <akim@epita.fr>
7105 * doc/autoconf.texi (Questions): Rename as...
7106 (FAQ): this.
7107 (Defining Directories): New.
7109 2002-09-09 Akim Demaille <akim@epita.fr>
7111 * doc/autoconf.texi (Making testsuite Scripts): Update.
7112 Suggested by Nishio Futoshi.
7114 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
7116 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
7117 plain `@' is wanted.
7119 2002-09-09 Akim Demaille <akim@epita.fr>
7121 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
7122 `duplicates', since the algorithm was too naive and could keep
7123 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7124 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7125 Reported by Ralf Corsepius.
7126 * tests/torture.at (Configuring subdirectories): Exercise these
7127 cases.
7129 2002-09-09 Akim Demaille <akim@epita.fr>
7131 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
7132 looking for a replacement file.
7133 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
7134 directory is relative.
7135 * doc/autoconf.texi (Generic Functions): Clarify the replacement
7136 directory definition.
7137 Reported by Andreas Schwab and Jim Meyering.
7139 2002-09-06 Akim Demaille <akim@epita.fr>
7141 * doc/autoconf.texi (Setting Output Variables): Clarify what
7142 precious variables are.
7143 Suggested by Pontus Skoeld.
7145 2002-09-05 Akim Demaille <akim@epita.fr>
7147 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7148 (ifnames, autoscan, autom4te): Since we don't only depend on
7149 configure.ac variables (such as VERSION etc.), but also on prefix
7150 and so forth, depend on Makefile, not configure.ac.
7151 Reported by Alexandre Duret-Lutz.
7152 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7154 2002-09-05 Kevin Ryde <user42@zip.com.au>
7156 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
7157 doesn't seem to be confined to ia64, just say "some versions".
7159 2002-09-04 Akim Demaille <akim@epita.fr>
7161 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
7162 Automake 1.6c.
7163 * Makefile.am (maintainer-clean-local): Remove.
7164 (MAINTAINERCLEANFILES): Remove COPYING.
7166 2002-09-03 Paul Eggert <eggert@twinsun.com>
7168 * doc/autoconf.texi (Configuration Commands): Remove obsolete
7169 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
7170 Brinkmann.
7172 2002-09-03 Akim Demaille <akim@epita.fr>
7174 * configure.ac: Bump to 2.53d.
7175 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
7176 as of today, on Automake's team suggestion.
7178 2002-09-03 Akim Demaille <akim@epita.fr>
7180 Version 2.53c.
7182 2002-09-02 Akim Demaille <akim@epita.fr>
7184 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
7185 SITE_MACRO_DIR.
7186 * configure.ac: Disable SITE_MACRO_DIR.
7188 2002-09-02 Jim Meyering <meyering@lucent.com>
7190 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
7191 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
7192 Also, tweak grammar: s/make sure to/be sure to/.
7194 2002-09-02 Paul Eggert <eggert@twinsun.com>
7196 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
7197 directory names are generally preferable to physical names.
7199 2002-09-02 Akim Demaille <akim@epita.fr>
7201 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7202 Reported by Raja R. Harinath.
7203 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7204 * bin/autoupdate.in: Use error instead of die.
7206 2002-09-01 Paul Eggert <eggert@twinsun.com>
7208 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7209 ordinary shell concatenation rather than echo+tr+sed command that
7210 runs afoul of a long-line-related sed bug in Solaris 8.
7212 * bin/autoheader.in (parse_args): --warning -> --warnings.
7214 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7215 stdout, as traditional "ls" does.
7216 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7217 _AC_COMPILER_EXEEXT_O): Likewise.
7218 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7220 * bin/autoconf.as: Add --prepend-include option. This patch was
7221 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7222 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7224 * bin/autoconf.in, configure: Regenerate.
7226 * doc/autoconf.texi (Special Shell Variables): Mention
7227 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7229 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7230 MAILPATH and set PS1, PS2, PS4 to default values, to work
7231 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7232 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7233 the Autoconf documentation specifies; fall back to "unset" only if
7234 this fails. Use a shell for-loop for this rather than an m4 loop,
7235 to shorten the output script.
7237 2002-08-30 Paul Eggert <eggert@twinsun.com>
7239 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7240 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7241 for the CDPATH problem. Document PWD.
7242 (Limitations of Builtins): Document the problem that "cd $foo" and
7243 "ls $foo" may refer to different directories in shells conforming
7244 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7245 example, since the old example is now out of date.
7247 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7248 FOO" and "ls FOO" talk about different directories; this catches
7249 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7250 spaghetti.
7252 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7253 of rolling our own unset.
7254 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7255 in practice we needn't worry about CDPATH if unset doesn't work.
7257 * Makefile.in, aclocal.m4, bin/Makefile.in,
7258 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7259 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7260 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7261 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7262 tests/Makefile.in: Regenerate with Automake 1.6.3.
7264 * config/config.guess, config/config.sub, config/mkinstalldirs:
7265 Update.
7267 * configure: Regenerate with self.
7269 2002-08-30 Kevin Ryde <user42@zip.com.au>
7271 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7272 default output.
7274 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7276 * bin/autom4te.in (Request::load): Correctly test for "do" read
7277 failure.
7279 2002-08-29 Akim Demaille <akim@epita.fr>
7281 * lib/Autom4te/General.pm (&xqx): New.
7282 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7283 hand, which is not portable.
7284 (&error): New.
7285 * bin/autom4te.in: Use them.
7286 Use &error instead of die.
7287 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7288 Adjust.
7290 2002-08-17 Paul Eggert <eggert@twinsun.com>
7292 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7293 default list of compilers to try, since it was long ago superseded
7294 by the ksh fc builtin. Suggested by Steven G. Johnson.
7296 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7298 * doc/autoconf.texi (Invoking autom4te): End the option table,
7299 fixing a bug introduced by the previous patch.
7300 (Limitations of Make): Add a 'target lookup' subentry in the
7301 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
7303 2002-07-29 Mark D. Roth <roth@feep.net>
7305 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
7306 options and use $AUTOM4TE_PATH.
7307 * doc/autoconf.texi: Remove documentation of autom4te
7308 --include-envvar and --site-macro-subdir options and document
7309 use of $AUTOM4TE_PATH.
7310 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
7311 arguments from each language section.
7313 2002-07-29 Paul Eggert <eggert@twinsun.com>
7315 * doc/install.texi: Include copyright symbol in copyright notice.
7317 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7318 Replace with:
7319 (AM_MAKEINFOFLAGS): New macro.
7320 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7321 * Makefile.am (INSTALL): Use the new macros.
7322 Use -o rather than --output, since "missing" does not grok --output.
7324 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7326 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7327 comments do not always work. Never trust the exit status of
7328 `make -k'.
7330 2002-07-24 Kevin Ryde <user42@zip.com.au>
7332 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7333 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
7335 2002-07-23 Paul Eggert <eggert@twinsun.com>
7337 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
7338 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
7339 apparently treats PATH="nonexistent" as if it contained ".".
7340 Bug reported by Stefan `Sec' Zehl.
7342 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7344 * doc/autoconf.texi (Limitations of Make): Mention the special
7345 handling of the obj/ directory by BSD make.
7347 2002-07-20 Kevin Ryde <user42@zip.com.au>
7349 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
7350 backslashes.
7352 2002-07-19 Akim Demaille <akim@epita.fr>
7354 * doc/autoconf.texi (Function Portability): `exit'.
7355 (Programming in M4sh): Ethymology of M4sh.
7357 2002-07-19 Akim Demaille <akim@epita.fr>
7359 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
7361 2002-07-18 Akim Demaille <akim@epita.fr>
7363 Version 2.53b.
7365 2002-07-18 Akim Demaille <akim@epita.fr>
7367 * config/config.guess, config/config.sub: Update.
7369 2002-07-18 Akim Demaille <akim@epita.fr>
7371 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
7372 Automake's parts.
7374 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
7375 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
7376 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
7378 2002-07-18 Akim Demaille <akim@epita.fr>,
7379 Alexandre Duret-Lutz <duret_g@epita.fr>
7381 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
7382 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
7384 2002-07-17 Russ Allbery <rra@stanford.edu>
7386 * doc/autoconf.texi (Initializing configure): Clarify the
7387 description of the tarname default.
7389 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
7391 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
7392 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
7393 latter was not run.
7395 2002-07-17 Akim Demaille <akim@epita.fr>
7397 * lib/Autom4te/General.pm (find_file): Browse the directories in
7398 the order they are given.
7400 2002-07-17 Akim Demaille <akim@epita.fr>
7402 * tests/wrapsh.as, tests/wrappl.as: Merge into...
7403 * tests/wrapper.as: this.
7404 * tests/Makefile.am, configure.ac: Adjust.
7406 2002-07-17 Mark D. Roth <roth@feep.net>
7408 * configure.ac: Add --enable-site-macro-dir option.
7409 * bin/Makefile.am: Expand @SITE_MACRO_DIR@.
7410 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
7411 --site-macro-subdir options.
7412 * bin/autoconf.in: Add --prepend-include option.
7413 * bin/autoheader.in: Add --prepend-include option.
7414 * bin/autoreconf.in: Add --prepend-include option.
7415 * bin/autoscan.in: Add --prepend-include option.
7416 * bin/autoupdate.in: Add --prepend-include option.
7417 * doc/autoconf.texi: Document use of $AC_MACRO_PATH and site
7418 macro directory, remove note that include path directories are
7419 used in reverse order, and document --prepend-include option.

7466 2002-06-27 Paul Eggert <eggert@twinsun.com>
7468 * config/install-sh: Quote $src. Prefer || to test's -o option,
7469 as per "Limitations of Builtins".
7470 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
7471 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.

7501 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>

7504 of the cache should not depend on the name under which autom4te
7505 was installed.
7507 2002-06-07 Akim Demaille <akim@epita.fr>

7513 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
7515 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
7516 _AC_LANG_PROGRAM_C_F77_HOOKS.

7523 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
7524 AC_FUNC_FNMATCH_GNU.
7526 2002-06-07 Akim Demaille <akim@epita.fr>
7528 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
7529 Rosetta Stone for Unix.
7531 2002-06-07 Akim Demaille <akim@epita.fr>
7533 * bin/autom4te.in (warn_forbidden): When rejecting a token,

7535 Suggested by Adam J. Richter.
7537 2002-06-07 Akim Demaille <akim@epita.fr>

7542 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

7555 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
7556 if ln doesn't work.

7596 version of Autoconf that is discussed.
7598 2002-05-22 Paul Eggert <eggert@twinsun.com>
7600 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
7601 from the default list of compilers to try. Suggested by
7602 Kate Hedstrom.
7603 * NEWS: Document the above.
7604 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
7606 2002-05-17 Paul Eggert <eggert@twinsun.com>
7608 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
7609 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
7610 This improves on an earlier suggestion by H. Peter Anvin.
7612 2002-05-16 Paul Eggert <eggert@twinsun.com>
7614 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7615 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7616 Both macros now accept an optional source-dir arg.
7617 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7619 * NEWS: Document this.
7620 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7622 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7623 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
7624 not for GNU extensions; this undoes part of the 2000-11-03 change,
7625 reverting to 2.13-compatible behavior.
7626 Add new optional argument DIR.
7627 (AC_FUNC_FNMATCH_GNU): New macro.
7629 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
7631 2002-05-08 Paul Eggert <eggert@twinsun.com>
7633 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7634 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7635 and it causes a 'test' syntax error if it fails.
7636 Bug reported by Stephen Gildea.
7638 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7639 If prototypes are supported, use them to check this at compile-time,
7640 instead of trying to check it at run-time. If we must do a run-time
7641 check, assume that setvbuf is standard when cross-compiling, as
7642 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7643 Bug reported by Paul D. Smith.
7645 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7646 argument specifying location of getloadavg.c. This removes a
7647 FIXME. This idea was taken from Jim Meyering's implementation in
7648 textutils.
7649 * doc/autoconf.texi (Particular Functions): Document this.
7650 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7651 that's what the code does; this fixes a bug reported by
7652 Paul D. Smith.
7654 2002-05-03 Akim Demaille <akim@epita.fr>
7656 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
7657 autopoint instead of gettextize.
7658 ($uses_alocal): Rename as...
7659 ($uses_aclocal): this.
7660 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7661 Suggested by Bruno Haible.
7663 2002-05-03 Akim Demaille <akim@epita.fr>
7665 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
7667 2002-04-29 Paul Eggert <eggert@twinsun.com>
7669 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7670 files to be 1 second older; just set them to be the same time.
7671 Also, sleep 1 second after the first aclocal, to work around
7672 problems with sub-second time stamps on the input files.
7674 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7676 * doc/autoconf.texi: Mention "set -e -x" lossage
7677 under node "Limitations of Builtins".
7679 2002-04-29 Akim Demaille <akim@epita.fr>
7681 * doc/install.texi: Better wording for setting variables when
7682 running configure.
7683 From Christian Cornelssen.
7685 2002-04-29 Akim Demaille <akim@epita.fr>
7687 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7688 of lack of $LINENO support, then the test will compare the $LINENO
7689 in testsuite vs. the lineno in the test file. This is wrong, of
7690 course.
7691 Be sure to protect it.
7692 Reported by Patrick Welche.
7694 2002-04-25 Akim Demaille <akim@epita.fr>
7696 * doc/autoconf.texi (Obsolete Macros): Typo.
7697 Reported by Vladimir Volovich.
7699 2002-04-25 Akim Demaille <akim@epita.fr>
7701 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7702 than some of the input files, hence, on the second run of aclocal,
7703 if some of its input are younger, make them older.
7704 Suggested by Paul Eggert.
7706 2002-04-25 Akim Demaille <akim@epita.fr>
7708 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
7709 Thanks to Paul Eggert.
7711 2002-04-25 Akim Demaille <akim@epita.fr>
7713 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
7714 and ac_subst_vars be sh variables containing the list of
7715 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7716 DEFAULT diversion.
7717 (_AC_INIT_PREPARE): Use them to log them.
7718 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7719 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7720 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7721 _AC_SUBST_FILES and _AC_SUBST_VARS.
7722 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
7724 2002-04-24 Akim Demaille <akim@epita.fr>
7726 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7727 autoheader, so that automake does not complain about a missing
7728 config.h.in that was to be created.
7730 2002-04-23 Akim Demaille <akim@epita.fr>
7732 * bin/autoheader.in (parse_args): --warning takes an argument.
7733 Fixes PR/220.
7735 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
7737 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

7782 Minor spelling and grammar fixes.
7784 * doc/autoconf.texi: Follow the outline suggested in the GNU
7785 Sample Texts sections of the Texinfo 4.2 manual. Most
7786 importantly, this makes sure that the copyright notices appear in
7787 all output formats. You probably need Texinfo 4.2 to generate
7788 the manual now.

7814 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
7816 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

7843 * lib/autotest/general.m4 (AT_INIT): Likewise.
7844 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

7848 Use this M4sh to generate Autoconf's shell scripts.
7850 * tests/wrapsh.as: New, precursor of wrapsh.in.

7893 Don't use the KILL diversion, as it kills spurious output, which
7894 results in failures being hidden.

7905 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
7906 expanded if $# <= 2.
7908 * bin/autoreconf.in (autoreconf): Run automake after rerunning
7909 aclocal.
7911 2002-04-03 Akim Demaille <akim@epita.fr>
7913 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
7914 (_AC_COMPILER_EXEEXT_REJECT): New.
7915 Also recognize *.bb and *.bbg as compilation byproducts.
7916 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
7917 (_AC_COMPILER_OBJEXT): Use them.
7918 Fixes Debian #138666.
7920 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
7922 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
7924 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
7925 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
7926 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
7927 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
7928 (AC_C_CONST): Same.
7929 (AC_C_INLINE): Same.
7930 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
7931 * doc/autoconf.texi, NEWS: Document.
7932 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
7933 AC_C_CROSS.
7935 2002-04-02 Akim Demaille <akim@epita.fr>
7937 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
7938 _AS_MKDIR_P_PREPARE.
7940 2002-03-28 Kevin Ryde <user42@zip.com.au>
7942 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
7943 to avoid versions of HP C which don't allow that.
7945 2002-03-27 Paul Eggert <eggert@twinsun.com>
7947 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
7948 (AS_SHELL_SANITIZE): Invoke it.
7949 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
7951 2002-03-26 Akim Demaille <akim@epita.fr>
7953 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
7955 2002-03-26 Akim Demaille <akim@epita.fr>
7957 * doc/autoconf.texi (Introduction): The GNATS base moved.
7959 2002-03-25 Paul Eggert <eggert@twinsun.com>
7961 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
7962 as POSIX requires, as it doesn't work with Zsh.
7963 * doc/autoconf.texi (Assignments): Document the problem.
7965 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7967 * doc/autoconf.texi (Limitations of Make): Mention more issue
7968 about VPATH, overriding of macros in sub-makes, and handling of
7969 SHELL.
7971 2002-03-21 Paul Eggert <eggert@twinsun.com>
7973 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
7974 problem with here-document buffer boundaries.
7976 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
7977 when reinvoking the shell, to work around problems with installers
7978 who put strange things like "cd" commands in their environments.
7980 2002-03-19 Akim Demaille <akim@epita.fr>
7982 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
7983 From Aaron Ucko.
7985 2002-03-19 Akim Demaille <akim@epita.fr>
7987 * bin/autoscan.in (scan_file): Specify the location in `&used'
7988 invocations.
7989 From Nicolas Joly.
7991 2002-03-19 Akim Demaille <akim@epita.fr>
7993 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
7994 From Nishio Futoshi.
7996 2002-03-19 Akim Demaille <akim@epita.fr>
7998 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
8000 2002-03-18 Paul Eggert <eggert@twinsun.com>
8002 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
8003 (Limitations of Usual Tools): Add mkdir section.
8005 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8006 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8007 back on AS_DIRNAME to compute prefixes otherwise; this is
8008 roughly what mkinstalldirs does. That way, we need not have
8009 our own filename disassembler. The old disassembler did not
8010 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8012 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8013 Create at_test_all by a series of assignments,
8014 not by a single assignment of a long string. The latter causes ksh
8015 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8016 presumably because of a buffer overrun.
8018 2002-03-14 Paul Eggert <eggert@twinsun.com>
8020 * lib/autotest/general.m4 (at_times_skip):
8021 Renamed from at_times. Now a boolean.
8022 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8023 says 'times: not found'.
8025 2002-03-14 Akim Demaille <akim@epita.fr>
8027 * bin/autoreconf.in (&study_gettextize): New.
8028 (&autoreconf): Handle newest gettextize.
8029 Rerun aclocal if needed.
8030 Suggested by Andreas Schwab.
8032 2002-03-13 Akim Demaille <akim@epita.fr>
8034 * doc/autoconf.texi (Special Shell Variables): More about IFS.
8036 2002-03-13 Akim Demaille <akim@epita.fr>
8038 * doc/autoconf.texi (Header Portability): New.
8039 Add information about stdint.h and inttypes.h from Paul Eggert.
8041 2002-03-13 Akim Demaille <akim@epita.fr>
8043 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
8044 -p'.
8045 From Bob Proulx.
8047 2002-03-12 Akim Demaille <akim@epita.fr>
8049 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
8050 m4_require.
8052 2002-03-11 Andreas Schwab <schwab@suse.de>
8054 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
8055 does not do it if --with-lispdir is given.
8057 2002-03-08 Akim Demaille <akim@epita.fr>
8059 Version 2.53.
8061 2002-03-08 Akim Demaille <akim@epita.fr>
8063 * doc/autoconf.texi (Subdirectories): Clarify that the
8064 subdirectory should exist.
8066 2002-03-08 Akim Demaille <akim@epita.fr>
8068 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
8070 2002-03-08 Akim Demaille <akim@epita.fr>
8072 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
8073 aliases the actual variables, and modifications of the former
8074 affect the latter.
8076 2002-03-08 Akim Demaille <akim@epita.fr>
8078 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
8079 because of C-c: have m4 output in tmp files, then mv them.
8081 2002-03-08 Akim Demaille <akim@epita.fr>
8083 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
8084 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
8085 * bin/ifnames.in: Copyright update.
8087 2002-03-08 Akim Demaille <akim@epita.fr>
8089 * doc/autoconf.texi (Invoking autom4te): New.
8091 2002-03-05 Akim Demaille <akim@epita.fr>
8093 * doc/autoconf.texi (Specifying Names): Clarification suggested by
8094 Kevin Ryde.
8096 2002-03-05 Akim Demaille <akim@epita.fr>
8098 Version 2.52i.
8100 2002-03-04 Akim Demaille <akim@epita.fr>
8102 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
8103 * lib/autoconf/general.m4 (AC_INIT): More informative error
8104 message for LIBOBJ.
8106 2002-03-04 Akim Demaille <akim@epita.fr>
8108 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
8109 parallel builds.
8111 2002-03-04 Akim Demaille <akim@epita.fr>
8113 * doc/autoconf.texi (Transforming Names): Equality between target
8114 and host is irrelevant.
8115 (Specifying Names, Canonicalizing): Remove all references to the
8116 backward compatibility hooks. Rather, collect them all into...
8117 (Hosts and Cross-Compilation): this new section.
8118 * doc/install.texi (System Type): Ditto.
8119 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
8120 that `--host' implies cross-compilation.
8122 2002-03-04 Akim Demaille <akim@epita.fr>
8124 * doc/autoconf.texi (Evaluation Macros): New.
8125 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8126 useless.
8127 (_m4_foreach): Define the variant with immediate evaluation so
8128 that it contains exactly the items, not an expression which
8129 evaluation is the current item.
8130 (m4_re_string, m4_re_word): Don't over quote them.
8132 2002-03-04 Akim Demaille <akim@epita.fr>
8134 Instead of having stacking `shift's evaluated at the end, let
8135 `foreach' loops immediately evaluate them.
8137 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8138 $*. This is the n-th time I change my mind, but hopefully this is
8139 the last...
8140 (m4_lquote): New.
8141 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8142 efficient.
8143 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8144 it was only a hack for m4_text_wrap.
8145 (m4_car2): Remove, replaced by...
8146 (m4_cdr): New.
8147 (_m4_foreach): Adjust.
8148 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8149 m4_bpatsubst for clarification.
8151 2002-03-04 Akim Demaille <akim@epita.fr>
8153 * doc/autoconf.texi (Changequote is Evil): New.
8155 2002-03-03 Kevin Ryde <user42@zip.com.au>
8157 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
8158 on old systems like SunOS.
8160 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
8162 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8163 lib/autoconf/functions.m4, lib/autoconf/general.m4,

8171 message to be sent.
8173 2002-02-28 Kevin Ryde <user42@zip.com.au>

8177 2002-02-25 Akim Demaille <akim@epita.fr>
8179 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
8180 From Akinori Musha.
8182 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
8184 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
8185 translate \r\n to \n.
8187 2002-02-07 Akim Demaille <akim@epita.fr>
8189 Version 2.52h.
8191 2002-02-07 Akim Demaille <akim@epita.fr>
8193 Fix Autoconf PR/209.
8194 Also reported by Frank Denis.
8196 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
8198 2002-02-07 Akim Demaille <akim@epita.fr>
8200 Fix Autoconf PR/207:
8201 AC_PREFIX_PROGRAM fails with dashed program names
8203 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
8204 variable when looking for the prefix program.
8205 Now it also works for shell variables.
8207 2002-02-07 Akim Demaille <akim@epita.fr>
8209 * doc/autoconf.texi (Limitations of Builtins): More about
8210 case/esac.
8212 2002-02-06 Akim Demaille <akim@epita.fr>
8214 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
8215 case/esac, some shells don't support it.
8216 Reported by Zack Weinberg.
8217 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
8219 2002-02-06 Akim Demaille <akim@epita.fr>
8221 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
8222 sure not to introduce newlines in at_groups.
8223 * lib/autotest/Makefile.am (autotest.m4f): Typo.
8225 2002-02-06 Akim Demaille <akim@epita.fr>
8227 * tests/torture.at (Configuring subdirectories): Skip if aclocal
8228 is not available.
8230 2002-02-05 Paul Eggert <eggert@twinsun.com>
8232 * doc/autoconf.texi (Specific Compiler Characteristics):
8233 Describe HP-UX cc bug workaround more accurately.
8234 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
8235 not unsigned long.
8236 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
8237 cross-compilers, too. This undoes some of the most recent change
8238 to this file.
8240 2002-02-05 Akim Demaille <akim@epita.fr>
8242 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
8243 to make sure they are up to date when `check' is run.
8245 2002-02-05 Akim Demaille <akim@epita.fr>
8247 * doc/autoconf.texi (Making testsuite Scripts): Document
8248 package.m4.
8250 2002-02-05 Akim Demaille <akim@epita.fr>
8252 * lib/freeze.mk: New.
8254 2002-02-05 Akim Demaille <akim@epita.fr>
8256 Implement `autom4te --freeze'.
8258 * bin/autom4te.in (&freeze): New.
8259 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
8260 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
8262 2002-02-05 Akim Demaille <akim@epita.fr>
8264 * bin/autom4te.in (&parse_args): Implement `frozen files are
8265 optional are the sum of the previous files on the command line'.
8266 Also, pass `--reload-state=' on them, so...
8267 (handle_m4): don't.
8268 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
8269 (M4sh): Rely on M4sugar.
8270 (Autotest, M4sh, M4sugar): Use frozen files.
8272 2002-01-31 Akim Demaille <akim@epita.fr>
8274 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
8275 * doc/autoconf.texi (Initializing configure): Adjust.
8277 2002-01-30 Akim Demaille <akim@epita.fr>
8279 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
8280 alphanumeric to `-' instead of `_'.
8282 2002-01-30 Akim Demaille <akim@epita.fr>
8284 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
8285 for plain code, the other for cross-compilation code. The latter
8286 is now run with GCC only.
8287 * doc/autoconf.texi (Compilers and Preprocessors): New.
8289 2002-01-30 Akim Demaille <akim@epita.fr>
8291 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
8292 values.
8293 * doc/autoconf.texi (Initializing configure): Explain how to
8294 change AC_INIT default values.
8296 2002-01-29 Akim Demaille <akim@epita.fr>
8298 * tests/torture.at (Configuring subdirectories): Use configure.in,
8299 so that aclocal 1.4 works.
8300 Reported by Alexandre Duret-Lutz and Larry Schmitt.
8302 2002-01-28 Akim Demaille <akim@epita.fr>
8304 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
8305 needs an argument.
8307 2002-01-28 Akim Demaille <akim@epita.fr>
8309 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8310 AUTOTEST_PATH *after* it was set.
8311 Don't put `.' in the PATH: the user should be precise and `./' if
8312 needed. In addition, given that the test suite does some `cd', if
8313 `.' is in the path, the `tested programs' sections will report
8314 programs found in the test suite's directory, while during the
8315 tests (performed in their own directory), these programs are no
8316 longer visible. In other words, the results is confusing and
8317 useless.
8318 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
8320 2002-01-24 Akim Demaille <akim@epita.fr>
8322 Version 2.52g.
8324 2002-01-24 Akim Demaille <akim@epita.fr>

8327 * doc/autoconf.texi: Finally add Akim as an author.
8329 2002-01-24 Akim Demaille <akim@epita.fr>
8331 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
8332 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
8333 Bourne. Use /bin/sh.
8334 From Andreas Buening.
8336 2002-01-24 Akim Demaille <akim@epita.fr>
8338 * config/config.guess, config/config.sub, config/texinfo.tex:

8347 * config/strip.m4: Remove, to ease sync'ing with any version of
8348 Automake.
8350 2002-01-24 Akim Demaille <akim@epita.fr>
8352 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
8353 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
8354 Reported by Geir Ove Myhr.
8356 2002-01-21 Akim Demaille <akim@epita.fr>
8358 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
8360 2002-01-21 Akim Demaille <akim@epita.fr>
8362 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
8363 message on invalid options.
8364 * bin/autom4te.in (parse_args): Don't use
8365 Autoconf::General::getopt with non valid options.
8367 2002-01-17 Jim Meyering <meyering@lucent.com>
8369 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
8370 $ac_cv_exeext so we don't use an old, invalid, cached value.
8372 2002-01-11 Akim Demaille <akim@epita.fr>
8374 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
8375 Meyering.
8376 * doc/autoconf.texi (Function Portability): Document the strnlen
8377 limitation.
8378 (Particular Functions): Document AC_FUNC_STRNLEN.
8379 * lib/autoscan/functions: Adjust.
8381 2002-01-06 Akim Demaille <akim@epita.fr>
8383 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
8384 package.m4, since is really depends upon configure.ac, not
8385 configure.
8386 * doc/autoconf.texi (testsuite Scripts): Adjust.
8387 * tests/Makefile.am (package.m4): New.
8388 EXTRA_DIST it since its a source.
8390 2002-01-06 Akim Demaille <akim@epita.fr>
8392 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
8393 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8394 and PACKAGE_BUGREPORT from here...
8395 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
8396 arguments.
8397 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
8398 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
8399 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
8400 * tests/tools.at (autoheader): Adjust.
8401 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
8403 2002-01-06 Akim Demaille <akim@epita.fr>
8405 * bin/autoscan.in (scan_file): Use `&used'.
8407 2002-01-03 Akim Demaille <akim@epita.fr>
8409 * doc/autoconf.texi (Output): Improved wording regarding use of
8410 AC_OUTPUT.
8411 From Olly Betts.
8413 2001-12-18 Kevin Ryde <user42@zip.com.au>
8415 * doc/autoconf.texi (Function Portability): Add notes on sscanf
8416 sometimes needing writable input.
8418 2001-12-17 Jim Meyering <meyering@lucent.com>
8420 * doc/autoconf.texi (New Macros): Tweak wording.
8422 2001-12-14 Akim Demaille <akim@epita.fr>
8424 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8425 trailing files, don't apply `-rf' to files which might not be
8426 created by configure (core, core.*, and *.core), but just `rm -f'.
8427 Suggested by Jonathan Kamens.
8429 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8431 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
8433 2001-12-14 Akim Demaille <akim@epita.fr>
8435 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8437 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
8439 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
8440 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
8441 abs_srcdir, top_srcpath to abs_top_srcdir.
8442 (_AC_OUTPUT_FILES): Adjust.
8443 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
8444 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
8445 * tests/wrappl.in, tests/wrapsh.in: Adjust.
8447 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
8449 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
8450 C/Fortran linking on HP/UX, by extracting the Fortran library
8451 search path from the LPATH line in the $F77 -v output.
8453 2001-12-12 Kevin Ryde <user42@zip.com.au>
8455 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
8456 forbidden file descriptors table.
8458 2001-11-26 Akim Demaille <akim@epita.fr>
8460 * bin/autoscan.in (%c_keywords): Build it at top level.
8461 Map to 1 in order to simplify its uses.
8463 2001-11-26 Akim Demaille <akim@epita.fr>
8465 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
8466 Remove $filepath, useless.
8467 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8468 variables, they are really part of the tokens.
8469 Split the input line on spaces and then look for tokens.
8470 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8471 because of `lex$U.$(OBJEXT)'.
8472 (&scan_files): Use "@list" instead of join.
8473 * doc/Makefile.am (CLEANFILES): Add *.fns.
8475 2001-11-26 Akim Demaille <akim@epita.fr>
8477 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
8478 Remove, replaced by...
8479 * tests/wrappl.in: Be common for all the Perl executables.
8480 In particular autoscan and autoheader want -I.
8481 * configure.ac: Adjust.
8482 * lib/autoscan/headers: errno.h is portable.
8484 2001-11-26 Akim Demaille <akim@epita.fr>
8486 * bin/autoscan.in (used): New.
8487 Use it.
8489 2001-11-26 Akim Demaille <akim@epita.fr>
8491 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
8492 directives.
8493 (&scan_sh_file): Remove a duplicate pattern.
8494 (&check_configure_ac): Use long options.
8495 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
8497 2001-11-26 Akim Demaille <akim@epita.fr>
8499 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
8500 Before, having a line containing the opening of a multi line
8501 comment made the whole line be ignored.
8503 2001-11-26 Akim Demaille <akim@epita.fr>
8505 * doc/autoconf.texi (Using an Autotest Test Suite): New.
8506 (testsuite Scripts): Be one of its subsection.
8507 (Autotest Logs): New.
8509 2001-11-26 Akim Demaille <akim@epita.fr>
8511 Test groups are now run two directories deeper.
8513 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
8514 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
8515 at_top_builddir.
8516 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
8517 top_srcdir, builddir and top_builddir.
8518 Use `at_*dir' relatively to the directory containing the
8519 suite, use `*dir' when relatively to the current group dir.
8521 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
8523 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
8524 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
8525 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
8526 spelling errors.
8528 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8530 * doc/autoconf.texi (Using System Type): Add an example of `case
8531 $host' usage so people quit using `case $target' everywhere.
8533 2001-11-22 Akim Demaille <akim@epita.fr>
8535 * doc/autoconf.texi (Installation Directory Variables): Englishoes
8536 spotted by Jim Meyering.
8538 2001-11-16 Paul Eggert <eggert@twinsun.com>
8540 This patch implements a `long double' suggestion by Oliver Kiddle.
8542 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8543 static, to catch errors if the value isn't known at compile-time
8544 and the compiler supports dynamic arrays. Change its name from
8545 `_array_' to `test_array' to avoid potential name clashes.
8546 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8547 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8548 better than double. Catch a bug in GCC 2.95.2 x86.
8549 * doc/autoconf.texi (C Compiler): Document the above.
8550 * NEWS: Likewise.
8552 2001-11-13 Akim Demaille <akim@epita.fr>
8554 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8555 hand.
8556 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8558 2001-11-13 Akim Demaille <akim@epita.fr>
8560 * lib/autotest/general.m4 (AT_INIT): After having run the test
8561 group, go back to the initial directory, not to at_suite_dir.
8563 2001-11-13 Akim Demaille <akim@epita.fr>
8565 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8566 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8567 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8568 option.
8569 (AT_CHECK_CONFIGURE): Use absolute paths.
8570 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8571 The problem is still the old one: there is no means in M4 (that I
8572 know about) to create a defining macro, because there is no means
8573 to create `$1' etc., therefore, the defining macro ``swallows''
8574 all the arguments meant to the defined macro.
8576 2001-11-13 Akim Demaille <akim@epita.fr>
8578 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8579 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8580 configure.ac.
8581 * tests/aclocal.m4: Remove, as it is no longer used.
8583 2001-11-13 Akim Demaille <akim@epita.fr>
8585 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8586 variable names when referring to a single test group, or to
8587 `suite' when referring to the whole test suite.
8588 `at_last_test' is removed: m4 compute at_format itself.
8589 (at_stdout, at_stder1, at_stderr): New variables.
8590 (AT_CHECK): Use them.
8592 2001-11-13 Akim Demaille <akim@epita.fr>
8594 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8595 in PATH.
8596 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8597 Do it as soon as a test fails, don't wait till the end of the test
8598 suite.
8599 Don't remove $as_me.[0-9]*, since these files no longer exist.
8601 2001-11-13 Akim Demaille <akim@epita.fr>
8603 * tests/tools.at: Use absolute paths, since we are no longer run
8604 in place.
8606 2001-11-13 Akim Demaille <akim@epita.fr>
8608 Now that tests are running in their own private dir, there is no
8609 need to list the files to remove at the end of tests groups.
8611 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8612 (AT_data_files, at_data_files): Remove.
8613 (AT_CLEANUP, AT_DATA): Simplify.
8614 (AT_INIT): Adjust.
8615 Remove the group dir if !debug && !failed.
8616 * tests/atspecific.m4: Adjust.
8618 2001-11-13 Akim Demaille <akim@epita.fr>
8620 Start a new layout for Autotest: `testsuite' creates
8621 `testsuite.dir' in which the at-check-line etc. files are to be
8622 found, and `testsuite.dir/003' where the test group 3 is run.
8624 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8625 at_check_line_file, at_format, at_test_normalized, at_group_dir
8626 are new variables.
8627 Create the directories.
8628 Use absolute paths for at- files.
8629 (AT_CHECK): Adjust.
8631 2001-11-11 Michael Matz <matz@kde.org>
8633 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8634 (m4_car2): New.
8635 (m4_car): Properly quote arguments.
8637 2001-11-13 Akim Demaille <akim@epita.fr>
8639 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8640 with stricter rules on LIBOBJS.
8642 2001-11-12 Paul Eggert <eggert@twinsun.com>
8644 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8645 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8646 __PROTOTYPES too.
8648 2001-11-12 Akim Demaille <akim@epita.fr>
8650 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8652 2001-11-12 Akim Demaille <akim@epita.fr>
8654 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8655 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8656 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8657 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8658 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8659 specify to what the macro should be defined (typically to 1).
8661 2001-11-12 Akim Demaille <akim@epita.fr>
8663 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8664 From Jim Meyering.
8666 2001-11-12 Akim Demaille <akim@epita.fr>
8668 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8669 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8670 definition used by Automake where LEX is +/- "${missing} lex" and
8671 `missing' itself contains variables.
8673 2001-11-12 Akim Demaille <akim@epita.fr>
8675 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8676 Now that M4sh pushes BODY, the comments were output at the end of
8677 the test suites.
8679 2001-11-08 Akim Demaille <akim@epita.fr>
8681 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8682 that we can trace macros from aclocal.m4.
8683 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8684 obsoleted, and redirect to the former anyway.
8685 Reported by Ralf Corsepius.
8687 2001-11-08 Akim Demaille <akim@epita.fr>
8689 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
8690 processed only if present.
8691 * tests/torture.at (Configuring subdirectories): Use autoreconf
8692 instead of successive calls to autoconf.
8693 Add a nonexistent subdirectory to exercise the patch above.
8694 Reported by Ralf Corsepius.
8696 2001-11-08 Kevin Ryde <user42@zip.com.au>
8698 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
8699 doesn't accept .S files.
8701 2001-11-07 Akim Demaille <akim@epita.fr>
8703 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
8704 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
8705 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
8706 * bin/autom4te.in (warn_forbidden): New.
8707 (handle_output): Use it.
8708 Read m4_pattern_forbid with messages.
8710 2001-11-05 Akim Demaille <akim@epita.fr>
8712 * bin/autom4te.in (--normalize): Remove.
8713 * lib/autom4te.in: Adjust.
8715 2001-11-05 Akim Demaille <akim@epita.fr>
8717 * tests/Makefile.am (testsuite): Rename this target as...
8718 ($(TESTSUITE)): this.
8719 From Nicolas Joly.
8721 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
8723 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
8724 the --prefix option, also remove it's argument.
8726 2001-11-05 Akim Demaille <akim@epita.fr>
8728 * doc/autoconf.texi (testsuite Invocation): Update.
8729 (Writing testsuite.at): Update.
8731 2001-11-03 Akim Demaille <akim@epita.fr>
8733 * doc/autoconf.texi: s/@code/@command/ where appropriate.
8735 2001-11-03 Akim Demaille <akim@epita.fr>
8737 * lib/Autom4te/General.pm: (&catfile, &canonfile)
8738 (&file_name_is_absolute): New, wrappers around routines from
8739 File::Spec.
8740 Use and export them.
8741 (&find_configure_ac): Optionally take a directory where to look at.
8742 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
8743 the arguments.
8744 Default @ARGV to `.', not find_configure_ac.
8745 (&autoreconf): Argument is a directory.
8746 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
8747 * doc/autoconf.texi (autoreconf Invocation): Update.
8749 2001-11-03 Akim Demaille <akim@epita.fr>
8751 * lib/Autom4te/General.pm (@export_vars, @export_subs)
8752 (@export_forward_subs): New.
8753 Add basename, dirname, and fileparse.
8754 (@EXPORT): Adjust.
8755 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8756 Don't look for aclocal flags if we already know aclocal is not
8757 used.
8758 Move aclocal.m4t only if it exists.
8759 Reported by Ezra Peisach.
8761 2001-11-03 Akim Demaille <akim@epita.fr>
8763 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8764 passed on command line, defaulting to ./configure.ac if present.
8765 (&maybe_autoreconf, File::Find): Remove, unused.
8766 (&autoreconf): If autoconf is not used, don't try to trace.
8768 2001-11-02 Akim Demaille <akim@epita.fr>
8770 * configure.ac: Bump to 2.52g.
8772 2001-11-02 Akim Demaille <akim@epita.fr>
8774 Version 2.52f.
8776 2001-11-02 Akim Demaille <akim@epita.fr>
8778 * config/config.guess, config/config.sub, doc/standards.texi:
8779 * config/lispdir.m4: Update from masters.
8780 * configure.ac: Bump to 2.52f.
8782 2001-11-02 Akim Demaille <akim@epita.fr>
8784 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8785 Don't run aclocal when aclocal.m4 is not from aclocal.
8786 From Ezra Peisach.
8787 Don't run libtoolize and gettextize if --install is not given.
8789 2001-11-01 Paul Eggert <eggert@twinsun.com>
8791 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8792 be invoked before _AS_LINENO_PREPARE.
8793 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
8794 than character ranges.
8796 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
8797 invoking AS_BASENAME. Set the locale variables to 'C' if
8798 possible, as POSIX requires this to get the traditional
8799 behavior.
8800 * doc/autoconf.texi (Special Shell Variables): Describe the above.
8802 2001-10-31 Paul Eggert <eggert@twinsun.com>
8804 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
8805 with {}, as that triggers a bug in Bash 2.05.
8807 (_AS_LINENO_PREPARE): Use Sed rather than
8808 Awk. Fix the sed prepass to work even if there are multiple
8809 instances of $LINENO on the same line. Do not substitute for
8810 other variables like $LINENOT. Do not check file dates; such a
8811 check is unreliable on sufficiently fast machines, and removing
8812 the check makes the code simpler and more reliable. Check for
8813 output and chmod failures.
8815 * doc/autoconf.texi (Special Shell Variables): Document
8816 the above.
8818 2001-10-31 Akim Demaille <akim@epita.fr>
8820 * tests/Makefile.am (atconfig): Remove this target, Automake
8821 handles it now.
8823 2001-10-31 Akim Demaille <akim@epita.fr>
8825 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
8826 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
8827 provided, while it is optional.
8828 * configure.ac: Adjust.
8830 2001-10-26 Paul Eggert <eggert@twinsun.com>
8832 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
8833 lib/Autom4te/Struct.pm:
8834 Require Perl 5.005_03 instead of just 5.005, as some tests fail
8835 with 5.005_02.
8837 * doc/autoconf.texi (Special Shell Variables): Document some
8838 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
8840 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
8841 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
8842 eval $LINENO is not portable in practice.
8844 2001-10-24 Akim Demaille <akim@epita.fr>
8846 * lib/Autom4te/General.pm (backname): New.
8848 2001-10-24 Akim Demaille <akim@epita.fr>
8850 * m4/: Remove, merged into...
8851 * config/: here.
8853 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
8855 * doc/autoconf.texi (Shellology): Mention the problems with bash
8856 2.05's use of ANSI quoting in its `set' builtin.
8858 2001-10-22 Paul Eggert <eggert@twinsun.com>
8860 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
8861 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
8862 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
8863 POSIX decided to standardize on the int flavor of strerror_r.
8864 Always do char* test, as there's no reason not to.
8865 Assign to a char* var, to catch strerror_r that returns int*.
8867 * doc/autoconf.texi (Particular Functions):
8868 Document the above changes. Also, document the fact that
8869 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
8871 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
8873 2001-10-20 Akim Demaille <akim@epita.fr>
8875 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
8876 the executable was missing from the log.
8878 2001-10-20 Akim Demaille <akim@epita.fr>
8880 * lib/Autom4te/General.pm (&update_file): If destination is
8881 unchanged, remove the source.
8882 (&up_to_date_p): Don't be verbose, be debug.
8883 * bin/autoreconf.in: No longer support --m4dir.
8884 (&autoreconf): Display the full path of the configure.ac we are
8885 studying.
8886 Trace it only once.
8887 Be sure to honor --force with gettextize.
8888 Always run aclocal.
8889 * doc/autoconf.texi: Adjust.
8891 2001-10-20 Akim Demaille <akim@epita.fr>
8893 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
8894 Remove, dead.
8895 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
8896 `intl' is already present, as it refuses unless --force.
8897 (&parse_args): Use -I, --include instead of the old Autoconf
8898 options.
8899 ($localdir, $autoconf_dir): Remove.
8900 (@include): New.

9209 * tests/fortran.at (GNU Fortran 77): there.
9210 * doc/autoconf.texi (autoconf Invocation): Fix the example:
9211 AC_TRY_RUN is about compilation, not shell commands.

9369 arguments. Fixed a typo.
9371 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9373 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
9374 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
9376 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9378 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
9379 * bin/autoupdate.in: Ditto.
9380 * bin/autoheader.in: Reworded a few comments.
9381 * bin/autoconf.in: Reworded help text for a few options.
9382 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
9383 * bin/autoscan.in, bin/autoupdate.in: Ditto.
9385 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9387 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
9388 already have $file). Set output files to binary mode (helps avoid
9389 CR issues on DOSish systems).
9391 2001-09-19 Akim Demaille <akim@epita.fr>
9393 * lib/autotest/general.m4: Englishoes.
9394 From Tim Van Holder and Alexey Mahotkin.
9396 2001-09-18 Paul Eggert <eggert@twinsun.com>
9398 * doc/autoconf.texi (Common Shell Constructs): New node,
9399 documenting AS_DIRNAME.
9400 (Limitations of Usual Tools): Refer to it when discussing dirname.
9401 Also, update discussion of POSIX standard to reflect latest draft.
9403 * lib/autoconf/c.m4:
9404 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9406 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9407 Do not pass a first argument with leading '-'
9408 to expr, by parenthesizing initial integers that might be negative.
9410 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9411 now merely checks whether it is an error to pass an argument
9412 to getpgrp.
9414 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9415 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9416 whether it is a (compile-time) error to pass an argument to
9417 getpgrp. This simpler test supports the revised documentation,
9418 and is all that AC_FUNC_GETPGRP's users really need.
9420 2001-09-18 Akim Demaille <akim@epita.fr>
9422 * doc/autoconf.texi (Limitations of Make) <$<>: New.
9424 2001-09-18 Akim Demaille <akim@epita.fr>

9427 `{}'.
9428 * lib/autotest/general.m4 (AT_INIT): Adjust.
9430 2001-09-18 Paul Wagland <paul@wagland.net>
9432 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
9433 correctly.
9434 Add test for AS_BASENAME.
9435 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9436 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9437 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9438 * tests/base.at: Fixed the expected responses. The old ones were
9439 one line out...
9440 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9441 the documentation claims it should (and how it behaved in 2.13).
9443 2001-09-18 Akim Demaille <akim@epita.fr>
9445 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9446 the AC_CONFIG_COMMANDS invocation.
9447 This also solves the name clash problems.
9448 Don't set the package's ID.
9449 * lib/m4sugar/Makefile.am (version.m4): Revamp.
9450 No longer to be shipped.
9451 (version.in): Remove.
9452 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
9453 * lib/autoconf/status.m4: Adjust.
9454 Use `m4_PACKAGE_STRING'.
9455 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9456 the only optional argument is the name of the test suite.
9457 Expect `package.m4' to define the package signature.
9458 * lib/autom4te.in (Autotest): Add `package.m4?'.
9459 * tests/Makefile.am (package.m4): New.
9460 * tests/suite.at: ifnames is a victim.
9462 2001-09-18 Akim Demaille <akim@epita.fr>
9464 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
9465 AC_LIBSOURCE, AC_CONFIG_FILES.
9466 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
9467 program version string doesn't match the package's.
9468 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
9469 after `(cached)'.
9471 2001-09-17 Paul Eggert <eggert@twinsun.com>
9473 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9474 Allow expression to return any value that can fit into unsigned long
9475 (not int, as before). Check for output errors.
9477 2001-09-17 Bruno Haible <haible@ilog.fr>
9479 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9480 Always include <stdio.h> and <stdlib.h>. Evaluate
9481 the expression in an extra function before these includes. Call
9482 fprintf "%d" only after ensuring the argument is of type 'int'.
9483 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
9485 2001-09-17 Paul Eggert <eggert@twinsun.com>
9487 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9488 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9489 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9490 when they don't exist.
9492 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
9493 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
9494 need it.
9496 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
9497 version with the version used by fileutils 4.1, except use
9498 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
9499 we don't need it.
9501 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
9503 2001-09-13 Akim Demaille <akim@epita.fr>
9505 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
9506 _first_.
9507 Reported by Gerrit P. Haase.
9509 2001-09-13 Akim Demaille <akim@epita.fr>
9511 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

9526 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
9527 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
9528 Likewise.
9529 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
9530 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
9531 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
9532 AT_tests_all for consistency.
9533 Set at_victims.
9534 (AT_VICTIMS): Similar to AT_KEYWORDS.
9535 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
9537 2001-09-13 Akim Demaille <akim@epita.fr>
9539 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
9541 2001-09-13 Akim Demaille <akim@epita.fr>
9543 * lib/autotest/general.m4 (AT_INIT): Create and remove
9544 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
9545 test suites can cohabit.
9547 2001-09-13 Akim Demaille <akim@epita.fr>
9549 * tests/mktests.sh: Don't output banners for empty test files.
9551 2001-09-13 Akim Demaille <akim@epita.fr>
9553 Test suites can be run independently of configure.

9601 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass
9602 PATH_SEPARATOR, let M4sh compute it.
9603 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): New.
9604 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

9617 2001-09-07 Akim Demaille <akim@epita.fr>

9622 related variables into `at_package_*'.

9634 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
9635 in addition, it introduces useless differences in logs.

9637 Adjust PATH computation.
9638 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

9649 From Uwe Seimet.

9655 2001-09-05 Akim Demaille <akim@epita.fr>
9657 Be ready to handle filenames as stupid as `dnl.at', for if even
9658 the maintainer is dumb enough to do that...
9660 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
9661 excellence in M4 quotation: consider `__file__' is active.
9663 And BTW, when invoking m4, pass the --include in the right order:
9664 the wrong one.
9666 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

9694 New, extracted from main.
9695 Use IO::File wherever possible.
9696 (input.m4): Be constant, use -I instead of hard coding $tmp.

9729 (testsuite Scripts): There is no such thing as `atconfig.in'.

9732 2001-08-31 Akim Demaille <akim@epita.fr>
9734 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
9735 inverse order.

9740 to m4sugar was lacking!
9742 2001-08-31 Akim Demaille <akim@epita.fr>
9744 * man/Makefile.am (.x.1): We really have to pass
9745 autom4te_perllibdir.
9747 2001-08-31 Akim Demaille <akim@epita.fr>
9749 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

9751 run is stupid.
9753 2001-08-31 Akim Demaille <akim@epita.fr>
9755 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
9756 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
9757 Use directly autom4te, not autoconf.

9783 (autoheader): Pass --force since the test suite goes too fast for
9784 the time stamps.
9785 Adjust to the new autoheader messages.
9787 2001-08-31 Akim Demaille <akim@epita.fr>

9813 Forward autom4te's options instead of interpreting them.

9830 2001-08-31 Akim Demaille <akim@epita.fr>

9833 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
9834 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
9835 installed peer executables, only PATH is allowed to resolve it.
9836 Pass `autoconf_dir' via options, not via invisible envvars.
9837 * lib/Autom4te/General.pm (&find_peer): Remove.
9838 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
9839 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
9840 * man/Makefile.am: Let help2man rely on PATH instead of trying to
9841 find the executables for it.
9842 * tests/Makefile.am: Major cleanup. Too lazy to document...
9843 * tests/atlocal.in: Remove all the obscure envvar manipulations.
9844 We only need PERL.
9845 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
9846 indeed related to running the test suite, while passing
9847 --autoconf-dir and others is related to running non installed
9848 Autoconf executables. So don't do that, leave it to...
9849 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
9850 * tests/autoscan: New.
9851 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

9868 Suggested by Paul Eggert.
9870 2001-08-29 Akim Demaille <akim@epita.fr>

9875 2001-08-29 Akim Demaille <akim@epita.fr>
9877 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

10047 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
10048 the name of the directory they're in, instead of the filename,
10049 since version.m4 is now in m4sugar, but m4_acversion must not be
10050 classified as an Autoconf macro.

10052 Rather, pass autoconf_dir to m4.

10138 * NEWS, README, README-alpha, TODO, tests/README: This package is
10139 `Autoconf', not `autoconf' (the executable).
10141 2001-08-20 Akim Demaille <akim@epita.fr>

10195 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
10196 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

10259 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

10337 autom4te.cache (it's a directory, not a file.
10338 * Makefile.am: Ditto (but maintainer-clean-local).
10340 2001-08-15 Akim Demaille <akim@epita.fr>
10342 * bin/autom4te.in (@m4_warning): New.
10343 (&handle_m4): Use it.
10344 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
10345 warnings are issued at each run.
10346 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
10347 is in the src tree.
10349 2001-08-15 Akim Demaille <akim@epita.fr>

10352 don't waste time running `autoupdate --version' works.
10353 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
10355 2001-08-13 Akim Demaille <akim@epita.fr>

10414 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10416 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
10417 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
10418 * doc/autoconf.texi (C Compiler Characteristics): Update
10419 documentation for AC_C_BIGENDIAN.
10421 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10423 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
10424 magic values from an object file when cross-compiling.
10425 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
10427 2001-08-10 Akim Demaille <akim@epita.fr>
10429 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10430 effects.
10431 Suggested by Russ Allbery.
10433 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10435 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10436 current $prefix to the sub-configures.
10438 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10440 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10441 extension (needed on BeOS). Reported by Guido van Rossum.
10443 2001-08-09 Akim Demaille <akim@epita.fr>
10445 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10447 2001-08-07 Akim Demaille <akim@epita.fr>
10449 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10450 removed.
10451 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10452 No need to remove the files before and after the each test, before
10453 each test and at the end of the suite is enough.
10454 Display only the children `times', not the shell's.
10455 If the test failed or was skipped, at-times is not available.
10457 2001-08-07 Akim Demaille <akim@epita.fr>
10459 Always produce testsuite.log, including when there are no
10460 failures. This helps getting information on skipped tests, and
10461 duration of the tests. Err, implement the latter btw.
10463 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10464 Dump information on the first run of each test.
10465 (AT_CLEANUP): Create `at-times' containing the duration of the
10466 test group.
10468 2001-08-07 Akim Demaille <akim@epita.fr>
10470 The use of `dumpstat' revealed that `len' was used although it
10471 should not. m4_text_wrap was using it, but in the Autoconf world
10472 where it is legal. Hence (i) test M4sh in its own world, not
10473 Autoconf's, and (ii), ahem, fix the bug :)
10475 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10476 does not like `' instead of [].
10477 (AT_INIT): Forbid `^_?AT_'.
10478 And don't output such tokens.
10479 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10480 `script.as', and `autom4te.cache'.
10481 Remove `empty' and `macro' which are no longer used.
10482 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10483 * tests/m4sugar.at: Use it.
10484 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
10486 2001-08-07 Akim Demaille <akim@epita.fr>
10488 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
10490 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
10492 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
10494 2001-08-04 Akim Demaille <akim@epita.fr>
10496 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
10497 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
10498 AC_TRY_LINK.
10499 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
10500 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
10501 (AC_F77_MAIN): Likewise.
10503 2001-08-04 Akim Demaille <akim@epita.fr>
10505 Don't rely on M4sugar outputting the patterns in files, since we
10506 might process the output _without_ running m4, hence without these
10507 files.
10509 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
10510 * bin/autom4te.in (@Request::includes): Remove, unused.
10511 (@Request::source): Rename as...
10512 (@Request::input): this.
10513 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
10514 (&handle_output): Fetch the patterns from the traces.
10515 `$forbidden' and `$allowed' are constant: use m//o.
10516 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
10517 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
10519 2001-08-04 Akim Demaille <akim@epita.fr>
10521 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
10522 autoconf', i.e., in addition to caching traces, cache the output.
10524 * bin/autom4te.in (Request::cache): Rename as...
10525 (Request::id): this.
10526 ($cache, $icache, $tcache, $ocache): New.
10527 (&handle_m4): Save M4 output in the cache instead of $tmp.
10528 (&handle_output): Adjust.
10529 (&up_to_date_p): Check that the output cache is up to date too.
10530 (top level): Run `&handle_m4' iff force or the cache is invalid.
10531 Run `&handle_output' if the output cache is more recent.
10533 2001-08-04 Akim Demaille <akim@epita.fr>
10535 * bin/autom4te.in ($force): New.
10536 (&parse_args, &print_usage): -f, --force is a new option.
10537 (&handle_output): CPP directives might have spaces after `#'.
10538 (&parse_args): The first file only can be frozen.
10540 2001-08-04 Akim Demaille <akim@epita.fr>
10542 Don't let autom4te compute the `include' traces several times:
10543 first check that the trace cache file is up to date, and then
10544 compare its timestamp with that of the output.
10546 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
10547 the preamble. Don't require 5.005 as Autom4te::General does it,
10548 and better yet (use `use', not `require'!).
10549 * lib/Autom4te/Struct.pm: Rename the last occurrences of
10550 Class::Struct as Autom4te::Struct.
10551 * lib/Autom4te/General.pm (File::stat): Use it.
10552 (&mtime): New, export it.
10553 * bin/autom4te.in: Use it.
10554 Declare `$req' is invalid if it is outdated.
10555 Don't declare it valid before saving it if something went wrong.
10557 2001-08-04 Akim Demaille <akim@epita.fr>
10559 Autom4te shall not encode Autoconf data, and preselecting traces
10560 must be proposed to the users.
10562 * bin/autom4te.in (@required_trace): Remove.
10563 (@preselect): New.
10564 (&parse_args, &print_usage): -p, --preselect is a new option.
10565 (&up_to_date_p): Adjust.
10566 * bin/autoconf.in: Preselect some Autoconf macros.
10568 2001-08-04 Akim Demaille <akim@epita.fr>
10570 * tests/tools.at (autoconf --trace: user macros): Check traces on
10571 macros invoked without arguments, and macros invoked with multiple
10572 lines arguments.
10574 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
10576 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
10577 arguments.
10579 2001-08-03 Akim Demaille <akim@epita.fr>
10581 * bin/autoconf.in ($@): Work around the usual sh bug.
10582 From Nicolas Joly.
10584 2001-08-03 Akim Demaille <akim@epita.fr>
10586 Clean up the handling of the M4 builtins tracing exception.
10588 * bin/autom4te.in (Request::request): Don't complete M4 builtins
10589 trace requests.
10590 (@m4_builtins): Rename as...
10591 (@m4_builtin): this.
10592 (%m4_builtin_alternate_name): New.
10593 (&parse_args): Complete the trace requests with alternate names.
10594 (&handle_traces): Hence no longer do it here.
10595 (&trace_requests): Remove, unused.
10597 2001-08-03 Akim Demaille <akim@epita.fr>
10599 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
10600 m4_if, and m4_wrap.
10602 2001-08-03 Akim Demaille <akim@epita.fr>
10604 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
10605 (m4_divert_pop): Dump the whole diversion stack when a diversion
10606 mismatch happens.
10607 * bin/autom4te.in (&handle_output): Remember of the first
10608 occurrence of a possibly undefined macro, not the last.
10609 Complain about the possibly undefined macros in the same order as
10610 the appear in the output.
10611 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
10612 * tests/tools.at (autoconf: forbidden tokens, basic)
10613 (autoconf: forbidden tokens, exceptions): No longer sort
10614 autoconf's stderr, as it is now deterministic.
10615 Check that `dnl' is caught.
10617 2001-08-01 Akim Demaille <akim@epita.fr>
10619 * configure.ac: Bump to 2.52c.
10621 2001-08-01 Akim Demaille <akim@epita.fr>

10631 2001-08-01 Akim Demaille <akim@epita.fr>
10633 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
10634 `die'.
10635 (&END): New.
10636 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
10637 `END', as `Autom4te::General::END' will be triggered.
10638 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
10639 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

11031 compiler, not the preprocessor.
11032 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): No longer use

11034 the right thing.
11035 * Makefile.am (.m4.m4f): Emphasize M4 error messages and fail
11036 earlier if there are.
11038 2001-07-03 Akim Demaille <akim@epita.fr>

11071 provide an alternate 'main' function name, using the 'main' from
11072 the Fortran libraries.
11073 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
11074 cross-language link tests can be performed successfully.
11075 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
11076 after $LIBS, for consistency; this should be the general rule since

11083 at-stdout and at-stderr instead of removing the newline
11084 from the echo output, which is not guaranteed to work.
11086 2001-06-28 Jens Petersen <petersen@redhat.com>
11088 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to

11148 three as failures are unlikely, and speed matters.
11150 2001-06-23 Akim Demaille <akim@epita.fr>
11152 * doc/autoconf.texi (Redefined M4 Macros): New.
11154 2001-06-23 Akim Demaille <akim@epita.fr>
11156 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): Consider
11157 inttypes.h is missing if it conflicts with sys/types.h, as on IRIX

11195 ./configure --program-suffix=foo produces `transform=s,$$,foo,;',
11196 but some sed choke on multiple `;', and other tools (e.g.,
11197 Automake), include the separator themselves.
11199 * acgeneral.m4 (AC_ARG_VAR): Be sure not to leave extra `;'.
11201 2001-06-19 Tim Van Holder <tim.van.holder@pandora.be>
