1 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
4 too drastic, even if Texinfo in theory requires it for info mode.
6 (config.status Invocation): Renamed back from Recreating a
7 Configuration).
8 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
9 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
11 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
13 * NEWS: Version 2.61a.
15 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
16 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
18 * NEWS: Document changes with echo and printf, and the lack
19 of limits on the total size of multi-line values of substituted
20 variables, and the AC_FUNC_FSEEKO fix.
22 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
24 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
25 Writing configure.ac.
26 (Autoconf Input Layout): Renamed from configure.ac Layout.
27 (Recreating a Configuration): Renamed from config.status Invocation.
28 (Obsolete Recreation): Renamed from Obsolete config.status Use.
29 (acconfig Header): Renamed from acconfig.h.
30 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
31 (Writing Testsuites): Renamed from Writing testsuite.at.
32 (Autom4te Cache): Renamed from autom4te.cache.
34 * BUGS: Remove mention of VPATH problem, since it's now documented
35 not to be a bug in the Autoconf build procedure itself, but rather
36 a problem with the proprietary `make' programs.
38 * doc/autoconf.texi (Build Directories): Add a cross reference
39 to VPATH and Make.
41 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
42 * doc/standards.texi: Sync from gnulib.
44 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
45 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
46 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
47 generated automatically.
49 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
51 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
52 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
53 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
55 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
57 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
58 `CEOF$ac_eof' special marker, the awk script cannot contain a
59 line matching `^CEOF', so this is not needed any more.
60 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
61 special marker in the test.
63 2006-12-06 Stepan Kasal <kasal@ucw.cz>
65 * tests/tools.at (autom4te preselections): Use `find -newer';
66 remove one of the sleeps.
68 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
69 more readable, using ...
70 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
72 * doc/autoconf.texi (autoheader Invocation): Do not double-
73 quote the parameter of `AH_BOTTOM' in the example.
75 2006-12-05 Stepan Kasal <kasal@ucw.cz>
77 * doc/autoconf.texi (Configuration Headers): Remove the
78 example with multiple input files.
79 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
80 multiple input files.
82 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
84 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
85 creating the awk substitution script, handle one input line at a
86 time, so that the maximum length of a substituted (multi-line)
87 value is not limited by the size of the sed pattern space.
88 The trade-off is a slightly repetitive sed script.
89 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
90 can only have up to 7 characters, due to Solaris 10 /bin/sed.
91 * tests/torture.at (Substitute a 2000-byte string): Increase the
92 test with several long lines, they should not be caught by sed
93 limits any more.
95 * tests/tools.at (autom4te preselections): New test, to flag
96 entries missing from autom4te.cfg.
97 Report by David Byron <dbyron@hheld.com>.
99 * tests/torture.at (Substitute a 2000-byte string): Actually use
100 AC_PROG_AWK, so the last change works as intended.
101 (Substitute and define special characters): Likewise.
102 (Substitute a newline): Likewise.
104 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
105 instead of `awk' consistently.
106 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
107 * tests/torture.at (Torturing config.status): Test both the
108 result of AC_PROG_AWK and plain awk.
109 (Substitute a 2000-byte string): Likewise.
110 (Substitute and define special characters): Likewise.
111 (Substitute a newline): Likewise.
113 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
115 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
116 can be assigned to a function pointer. Problem reported by
117 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
118 part of a patch by Ralf Wildenhues in that same bug report.
120 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
122 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
123 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
125 2006-12-01 Eric Blake <ebb9@byu.net>
127 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
128 cross-compiling from cygwin to mingw.
129 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
130 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
131 to lib/autoconf/c.m4.
133 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
135 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
136 string for more reliable failure. Wrap the entire test that
137 causes the broken Solaris printf to dump core, in a subshell,
138 so the segmentation fault message is reliably suppressed.
139 Fix shell expansion errors by using /usr/ucb/echo always;
140 avoid an error on systems without it by another subshell.
141 Avoid m4 expansion of `$1'. Set the zeroth argument of the
142 subshell-$as_echo to `as_echo', for better error message.
144 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
146 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
147 `BASH_SOURCE' contain a newline, set them to empty, as they may
148 not be unset.
150 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
152 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
153 years and is too hard to maintain now. The last straw was
154 reported by Jerker Baeck in
155 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
156 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
157 * doc/autoconf.texi (Particular Functions): Move
158 AC_FUNC_SETVBUF_REVERSED from here...
159 (Obsolete Macros): ... to here. Say that it does nothing now.
160 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
161 Turn into (almost) a no-op.
163 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
164 (AC_C_VOLATILE):
165 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
166 These macros are obsolescent and new applications shouldn't need them.
167 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
168 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
169 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
170 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
171 (AC_FUNC_VPRINTF): Likewise.
172 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
173 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
174 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
176 * doc/autoconf.texi (Setting Output Variables): Mention that
177 @VAR1@VAR2 has unspecified behavior. Problem reported by
178 Ralf Wildenhues.
179 * NEWS: Mention this.
181 * Makefile.am: Put only a single '#' into the copyright notice,
182 so that it's also present in the output file. Standardize wording
183 in makefile copyright notices to match GNU coding standards.
184 * bin/Makefile.am: Likewise.
185 * doc/Makefile.am: Likewise.
186 * lib/Makefile.am: Likewise.
187 * lib/freeze.mk: Likewise.
188 * lib/autoconf/Makefile.am: Likewise.
189 * lib/autoscan/Makefile.am: Likewise.
190 * lib/autotest/Makefile.am: Likewise.
191 * lib/m4sugar/Makefile.am: Likewise.
192 * man/Makefile.am: Likewise.
193 * tests/Makefile.am: Likewise.
194 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
195 one-line file.
197 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
199 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
200 in the sed script that mangles the awk script: delete up to the
201 first exclamation mark only.
202 * tests/torture.at (Substitute and define special characters):
203 Test '!' too.
205 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
207 Rewrite config files generation: avoid quadratic growth in
208 the number of substituted variables by using awk instead of sed
209 for the bulk of the substitutions.
210 * NEWS: Mention this.
211 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
212 forbidden in the output (and thus input) file.
213 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
214 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
215 generate just one large awk script for substitutions,
216 eliminating much of the earlier complexity, while adding some
217 new complexity. Only expand the substitution templates at
218 configure time, for smaller configure script size. If
219 _AC_SUBST_FILES are used, test 'awk' for working getline support
220 at config.status time. If absent, interpolate through the
221 shell. The awk script was written with much help
222 from Paolo Bonzini and Paul Eggert.
223 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
224 (_AC_SED_FRAG_NUM): Likewise.
225 (_AC_SUBST_CMDS): Renamed from...
226 (_AC_SED_CMDS): ...this.
227 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
228 * tests/torture.at (Substitute a 2000-byte string): Also
229 substitute a line with 1000 words, and a variable with several
230 long lines.
231 (Substitute and define special characters): Test awk special
232 characters, and put substitution input strings `@foo@' in the
233 output, to test that no recursion happens; test several other
234 combinations from Paolo Bonzini.
236 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
238 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
239 that replaced echo with AS_ECHO where this wasn't necessary.
240 Problem reportd by Ralf Wildenhues.
241 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
242 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
243 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
245 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
247 * lib/freeze.mk (GREP): Removed, no need to initialize this.
249 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
251 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
252 that traditional Awk lacks 3-arg "split". It has it.
253 Mention that FS must be a single character, and a few other
254 99-byte limits of traditional Awk.
255 Mention that if (i in a) doesn't work with traditional Awk.
257 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
259 * tests/autotest.at (BSx641-newline in command):
260 (BS-BS-newline in command, BSx640-newline in command):
261 (Newline-CODE-BS-newline in command):
262 (Single-quote-BS-newline in command):
263 (Single-quote-newline-BS-newline in command):
264 Use printf '%s\n' instead of echo, for portability to hosts
265 where echo interprets backslashes. This will break on hosts
266 that lack printf, but for now let's assume all such hosts
267 are dead (if not, we should get reports of test failures).
269 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
271 'echo' has some portability problems, when given a first argument
272 with a leading '-', or when given any argument containing '\'.
273 Avoid using 'echo' in these cases.
274 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
275 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
276 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
277 * lib/autotest/general.m4 (AT_INIT): Likewise.
278 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
279 argument might be unportable.
280 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
281 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
282 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
283 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
284 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
285 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
286 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
287 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
288 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
289 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
290 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
291 (AC_PROG_MAKE_SET): Likewise.
292 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
293 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
294 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
295 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
296 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
297 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
298 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
299 * bin/autoconf.as: Redo verbose flag implementation, as the old
300 scheme wouldn't work with AS_ECHO.
301 * lib/autotest/general.m4 (AT_INIT): Likewise.
302 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
303 Don't use ECHO_T, since ECHO_N is now reliable.
304 * lib/autotest/general.m4 (AT_INIT): Likewise.
305 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
306 rather than using a here-document to put the script into a file.
307 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
308 use AS_ECHO.
309 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
310 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
311 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
312 bug, but we might as well stop using ECHO_N and ECHO_C internally.
313 * lib/autotest/general.m4 (AT_SETUP): Likewise.
314 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
315 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
316 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
317 operand, as AS_ECHO requires. Avoid double file name expansion.
318 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
319 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
320 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
321 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
322 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
323 Double-quote strings that would otherwise contain M4 comments.
324 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
326 * configure.ac (AC_INIT): Bump to 2.61a.
327 * NEWS: Likewise.
329 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
331 Version 2.61.
333 * configure.ac (AC_INIT): Bump to 2.61.
334 * NEWS: Likewise.
336 * tests/autotest.at (Macro with backslash in a test title):
337 Comment out for now, as this tests neither fails nor passes
338 reliably. Problem reported by Ralf Wildenhues.
340 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
342 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
343 in previous change, which caused test failures.
345 2006-11-16 Stepan Kasal <kasal@ucw.cz>
347 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
348 code for --enable, --disable, --with, and --without to...
349 (_AC_INIT_PARSE_ENABLE): ... a new macro.
350 * doc/autoconf.texi (Package Options):
351 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
353 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>

412 first argument may also contain dots.
414 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
416 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
417 benefit of platforms like Solaris+GCC where it is common to have a
418 non-working g++ installation.
420 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
421 and Joel E. Denny <jdenny@ces.clemson.edu>
422 and Paul Eggert <eggert@cs.ucla.edu>

426 ./micro-suite.
428 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
430 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
431 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
432 Imported from a similar patch to gnulib by Bruno Haible.
434 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
436 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
437 * doc/autoconf.texi (C Compiler): Document them.
438 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
439 New macros, taken from gnulib.
441 2006-11-07 Paul Eggert <eggert@cs.ucla.edu>
443 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Detect bug in

452 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
453 and Stepan Kasal <kasal@ucw.cz>
455 Handle special characters in test case titles correctly.

461 ./micro-suite -l and the title in micro-suite.log.
462 (Backquote in a test title,
463 Single-quote in a test title,
464 Double-quote in a test title): Don't expect failure anymore.
465 (Backslash in a test title): Put a non-whitespace character after the
466 backslash so that Bourne shells might actually see it as an escape
467 sequence.
468 (Brackets in a test title,
469 Pound in a test title,
470 Comma in a test title,
471 Quoted Macro in a test title,
472 Macro in a test title,
473 Macro with single-quote in a test title): New tests.
474 (Macro with backquote in a test title,
475 Macro with double-quote in a test title,
476 Macro with backslash in a test title): New tests expected to fail.
477 * tests/torture.at (#define header templates): M4-quote this title in
478 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
479 The visible effect was a stray [] in the testsuite output.
481 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
483 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
484 `trap ... 0' inside a function, for AIX sh.
486 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
488 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
489 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
490 5363) simply issues a warning when dividing by zero at compile
491 time. Problem reported by Elias Pipping.
493 2006-10-26 Eric Blake <ebb9@byu.net>
495 * THANKS: Update.
496 * doc/autoconf.texi (Evaluation Macros): Improve the example to
497 show effect on macros that expand with commas.
498 Reported by Joel E. Denny.
500 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):

520 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
522 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
524 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
525 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
526 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
527 reported by Nelson H. F. Beebe for Coreutils 6.4.
529 * tests/tools.at (autoconf --trace: user macros): Remove test
530 for tracing multiline macros, since m4 1.4.7a uses a different
531 way to number lines. Problem reported by Ralf Wildenhues.
533 2006-10-24 Stepan Kasal <kasal@ucw.cz>
535 * bin/autom4te.in (handle_m4): Do not redirect stdin to
536 /dev/null since the heuristics for interactive behaviour was
537 fixed in CVS m4.
539 * bin/autom4te.in: With --force, always refresh the output
540 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
542 * bin/autoconf.as: Fix the verbose message at the end.
544 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

555 * build-aux/texinfo.tex: automake 1.10
557 * NEWS: Remove AC_CACHE_CHECK_INT.
558 * doc/autoconf.texi (Caching Results): Likewise.
559 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
560 AC_CACHE_CHECK_INT, since it's no longer public.
561 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
562 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
564 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

573 m4_mkstemp.

582 Standards.

592 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
593 looking for special shell characters.
594 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
595 macro defined by AS_VAR_PUSHDEF before passing it as a
596 parameter.
597 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
598 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

607 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
609 (Imported from Automake.)
610 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
611 which incorrectly sets the mode of an existing destination
612 directory. In some cases the unpatched install-sh could do the
613 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
614 system. We hope this is rare in practice, but it's clearly worth
615 fixing. Problem reported by Alex Unleashed in
616 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
617 Also, don't bother to check for -m bugs unless we're using -m;
618 suggested by Stepan Kasal.
620 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
622 Import this change from Automake:
624 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>

627 Report from Bruno Haible.
629 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

633 Import this change from Config:
635 2006-09-20 Ben Elliston <bje@gnu.org>
636 * build-aux/config.sub (score, score-*): New.
638 Import this change from Gnulib:
640 2006-09-16 Karl Berry <karl@gnu.org>
641 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
642 to avoid sectioning errors.
644 Import these changes from Texinfo:
646 2006-10-04 Karl Berry <karl@gnu.org>
647 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

650 (\lquoteexpand, \quoteexpand): new defs.
651 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
652 (\code): must use new \...Char values, since now ` is active.
654 2006-08-26 Karl Berry <karl@gnu.org>
655 * build-aux/texinfo.tex (\textdegree): New command.
657 2006-08-12 Karl Berry <karl@gnu.org>
658 * build-aux/texinfo.tex (error \box0): smaller font.

662 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
664 2006-10-13 Stepan Kasal <kasal@ucw.cz>
666 * doc/autoconf.texi (Autoheader Macros): Warn that the text
667 added to the template can get mangled.
669 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
671 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
672 include the default headers, and redefine obstack_chunk_alloc
673 and obstack_chunk_free. Fixes false failure with glibc.
675 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
677 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
678 for backward compatibility with Libtool 1.5.22. Problem reported
679 by Ralf Wildenhues.
681 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
683 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
684 AC_PROG_CC.
685 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
687 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
689 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
690 the NonStop platform.
691 * doc/autoconf.texi (Posix Variants): Likewise.
692 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
694 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
695 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
696 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
697 Use a better substitute, by inspecting the output of "ls"
698 rather than just using ":".
699 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
700 rather than AS_EXECUTABLE_P, since we needn't worry about
701 non-regular files here.
703 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
704 due to configuration hassles with this. See Tonya Underwood's report
705 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
706 * doc/autoconf.texi (Special Shell Variables): Likewise.
708 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
709 Stepan Kasal <kasal@ucw.cz>
711 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
712 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
714 2006-10-11 Stepan Kasal <kasal@ucw.cz>
716 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
717 initialization which is not inherited through the environment
718 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
719 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
721 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
723 * doc/autoconf.texi (Limitations of Usual Tools): Describe
724 problems with mkdir -p -m.
726 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
728 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
729 comment about ac_cpp_err; it was incorrect, and anyway
730 ac_cpp_err is being removed below.
731 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
732 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
733 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
734 nobody uses it.
735 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
736 with werror_flag and conftest.err and so forth. This is more
737 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
738 and anyway the user shouldn't normally want to see this gorp logged.
739 Problem reported by Ralf Wildenhues.
740 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
741 empty, not 'no', since the rest of the code uses 'test -z'.
743 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
745 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
746 Use a single call to AC_DO_TOKENS rather than multiple, for
747 efficiency.
748 (_AC_LINK_IFELSE): Test that resulting file is executable.
749 Problem reported by mwoehlke in
750 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
752 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
753 than creating a file to use with test -x; this is much faster.
755 2006-10-02 Bruno Haible <bruno@clisp.org>
757 * lib/autom4te.in (Automake-preselections): Add
758 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
760 2006-09-27 Stepan Kasal <kasal@ucw.cz>
762 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
763 standard error, `experr' should be used, not `expout'.
765 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
767 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
768 fseeko testing program twice; just use the earlier result.
769 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
770 Set cache var to 'unknown' (not 'no') if leaving the macro unset
771 still doesn't let the program compile.
772 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
773 failed.
775 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
776 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
777 include it, without including anything else.
778 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
779 expressions.
780 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
782 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
784 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
785 `error.h', and include it, for a `error_at_line' prototype.
786 Use a nonempty format string in the link test.
787 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
788 for a declaration of wait3.
790 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
792 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
793 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
794 can apply to constants too, and that it checks for macro defns.
795 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
796 and simply cast the identifier to void. This handles structure
797 values. Problem reported by Ralf Wildenhues.
798 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
800 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
802 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
803 structure, and function symbols.
805 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

854 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
855 --error-output, to avoid warnings with M4 2.0.
857 2006-09-19 Stepan Kasal <kasal@ucw.cz>
859 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be
860 consistent with _AH_CHECK_FUNCS and _AH_CHECK_HEADERS.
861 * lib/autoconf/headers.m4 (AH_CHECK_HEADERS_DIRENT): Likewise.
863 2006-09-15 Stepan Kasal <kasal@ucw.cz>

868 2006-09-14 Stepan Kasal <kasal@ucw.cz>
870 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
871 mistaken comment: the path has to be relative; do not use
872 the path at runtime.
874 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
876 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

880 for both changes.
881 * doc/autoconf.texi (Setting Output Variables): Fix example to
882 not show `--silent' being passed to a `configure' re-run.
884 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
886 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
887 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
888 for the existence of the directory at configure-time. That's
889 too late, anyway. Problem reported by Stefan Seefeld.
891 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
892 7.1.4 /usr/bin/posix/sh described by Tim Rice in
893 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
895 2006-09-11 Stepan Kasal <kasal@ucw.cz>
897 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
898 works with GNU M4 1.4.3 again; make the normalized form
899 match the current m4 message; fix the description.
900 * test/tools.at (autom4te cache): Adapt to the change.
902 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
904 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
905 to catch glibc bug 2821
906 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
908 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
909 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
910 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
911 assume C89.
913 2006-09-08 Stepan Kasal <kasal@ucw.cz>
915 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the
916 preselections ...

929 by Dries Kimpe.
931 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
933 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
934 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
935 accept files with extension `.f'. For consistency, also prefer
936 xlf over f77.
937 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
938 from last patch.
940 2006-09-05 Romain Lenglet <rlenglet@users.forge.objectweb.org>

953 before AC_PROG_FC, due to a bug in Autoconf.
955 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
957 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
958 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
959 except the first two arguments are reversed.
960 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
961 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
962 caches nor outputs a diagnostic. Suggested by Bruno Haible.

972 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
973 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
974 programs should use their Gnulib counterparts.
975 * doc/autoconf.texi (Particular Functions): Likewise.
976 (Macro Names, testsuite Invocation): Replace uses of these
977 obsolete macros with uses of non-obsolete macros.

1003 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
1005 Fix Lex library problem reported to us by Julio Garvia.
1006 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
1007 for the default, which the user can override.
1008 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
1009 deal with LEXLIB.
1010 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
1011 didn't work if some values were cached but not others. Test for
1012 broken lex libraries like native ia64-hp-hpux11.22; see
1013 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1014 work around the problem by preferring an empty LEXLIB to -lfl or
1015 -ll. Let the user set LEXLIB='' to indicate no library needed.
1017 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
1018 * README: Likewise.
1019 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

1120 * doc/autoconf.texi (Particular Programs): Mention that
1121 @INSTALL@ and @MKDIR_P@ may vary for different output files.
1122 Reported by Alexandre Duret-Lutz.
1124 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
1126 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore

1143 -Wundef -Werror". Problem reported by David Fang in
1144 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
1145 * doc/autoconf.texi (Header Templates, Default Includes):

1160 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
1161 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
1162 this.

1166 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1167 problems with arg script text that doesn't end in newline, and

1182 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1183 --help' should mention that `--version' outputs configuration
1184 settings. Report by Bruno Haible.
1186 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1188 Fix test suite failures reported by Pierre in

1204 less skeptical about "volatile", after discussion with
1205 Bruno Haible on bug-gnulib.
1206 (Limitations of Usual Tools): Warn about sed stripping
1207 leading white space from text. From Bruno Haible.
1209 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1211 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1212 compiler complains about it, even if things works after the
1213 complaint. Problem reported by Peter O'Gorman.
1215 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1216 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1217 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1219 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1221 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

1229 to match M4 1.4.5.
1231 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1233 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1234 under AC_C_VOLATILE.
1235 (Volatile Objects): Be a little less skeptical about what
1236 "volatile" means. Derived from thoughts by Ben Pfaff in
1237 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1239 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1243 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1245 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1246 more globally, since the 2006-06-30 patch didn't suffice. Problem
1247 reported by Keith Marshall. Also, don't bother with builddir2,
1248 since it shouldn't be needed any more.
1250 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1252 * doc/autoconf.texi (Generic compiler characteristics):
1253 Document AC_COMPUTE_INT. Fix wrong statements on Default

1267 * NEWS: Document previous change.
1269 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1271 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1272 Require that long long int be at least 64 bits wide. C99 requires
1273 this and enough programs depend on it so we should check for it.
1274 Bruno Haible reports in
1275 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1276 that long long int is 32 bits wide with some nonstandard compilers.
1277 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1279 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1281 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1282 to a nonexistent file, so that we don't have to worry about
1283 a local site configuration that doesn't use /usr/local.
1284 Problem reported by Keith Marshall in
1285 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1287 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1289 * doc/autoconf.texi: Be more consistent about using @acronym with
1290 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1291 quite right (it talked about "OSF/Tru64", even though the
1292 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1293 and it even mentioned "OSF 4"!) and at this point there's little
1294 reason to talk about OSF any more, since it died in 1994.
1295 (Specific Compiler Characteristics): Simplify example of
1296 negative-size array.
1297 (File Descriptors): Reorder to make the text flow better.
1298 Remove joke about "appreciate the various levels"; I didn't get it.
1299 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1300 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1301 (File Descriptors, Limitations of Usual Tools):
1302 Tone down the advice against renaming or removing open files.
1303 (Limitations of Usual Tools): Add a new section, on 'rm'.
1305 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1307 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1308 -lXt in LIBS, idea from Karsten Hopp; this was due since
1309 this change:
1311 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1312 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1313 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1314 (which belong to Xt, not X itself). See Debian bug 327655.
1316 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1318 * configure.ac (AC_INIT): Bump to 2.60a.

1332 quadrigraph correctly in traces.
1334 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1335 Fix typos.
1337 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1338 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1339 not defined.
1340 * doc/autoconf.texi (Changed Directory Variables): New node,
1341 to document the whole `datarootdir' business a bit better.
1342 * NEWS: Update.
1343 * tests/torture.at (datarootdir workaround): Extend test.
1344 Prompted by report by Alexandre Julliard.
1346 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1348 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility

1350 fix reported by Larry Jones.
1352 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1354 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1355 about literal '${datarootdir}' if a definition is found in the
1356 output file.
1358 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1360 * NEWS: Use "M4" rather than "m4" when appropriate.
1361 Problem reported by Eric Blake.
1362 * doc/autoconf.texi: Likewise.
1363 Use @acronym around BSD, GCC, and GNU when appropriate.
1364 (Why GNU M4): Renamed from "Why GNU m4".
1365 (Redefined M4 Macros): Mention that Posix
1366 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1367 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1368 to int.
1370 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1372 * bin/autom4te.in (handle_output): Do not forbid the empty
1373 pattern.
1374 * tests/tools.at (autoconf: the empty token): New test.
1376 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1378 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1379 calls, so that we do not care whether they are LIFO or FIFO;
1380 in the m4_wrap, do not check which diversion is the topmost
1381 one, just check that the stack is balanced at the end.
1382 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1383 base diversion forever--pop the previous diversion before
1384 opening the new one; consequently, remove the m4_wrap call.
1385 * lib/autotest/general.m4 (AT_INIT): Likewise.
1386 * tests/m4sugar.at: Do not use
1387 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1389 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1390 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1392 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1393 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1394 Rework example of m4wrap token-pasting trouble so that it doesn't
1395 care whether it's LIFO or FIFO.
1396 Fix some "contrary to"s that are awkward in English.
1398 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1400 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1401 to `yes' instead of `int$1_t' if the type is found, for more
1402 consistent configure output (where $1 is the number of bits).
1403 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1404 Suggested by Bruno Haible.
1406 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1407 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1408 with system headers. Report by Bruno Haible.
1410 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1412 * config/config.guess, config/config.sub: Sync from upstream.
1414 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1415 in order to avoid picking up an older installed frozen m4sh.m4f.
1416 Besides an outdated shell startup, this could have been created
1417 by an earlier M4 version with incompatible frozen file format.
1419 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1421 * README: Recommend m4 1.4.4 instead of 1.4.3..
1422 * doc/autoconf.texi: Likewise.
1423 (Special Chars in Names): Say that $(.FOO) is portable, as
1424 suggested by Stepan Kasal.
1425 (Installation Directory Variables, Build Directories):
1426 (Automatic Remaking, Subdirectories, Fortran Compiler):
1427 (Making testsuite Scripts, Defining Directories):
1428 Quote variable usages better.
1429 (Making testsuite Scripts): Add clean-local rule to makefile
1430 snippet, by Eric Blake.
1431 (Installation Directory Variables): Fix table item font.
1432 Reword slightly to clarify. Generalize advice about
1433 not using special characters to include all file-related
1434 vars, not just VPATH.
1435 (Special Chars in Variables): Warn about special characters in
1436 $(srcdir) too.
1437 (Assignments): Clarify default-value example as suggested by
1438 Ralf Wildenhues in
1439 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1440 (Special Shell Variables): Note leading ./ or ../, as suggested
1441 by Eric Blake.
1442 (Limitations of Builtins): Under cd, warn about CDPATH.
1443 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1444 Ralf Wildenhues.
1446 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1448 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1449 `@var', for texi2html.
1450 (Systemology): Some more word wrapping, for DVI output.
1451 (autom4te Invocation): The short option for `--melt' is `-M',
1452 not `-m'.
1454 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1456 * doc/autoconf.texi: More formatting and English tweaks,
1457 many suggested by Ralf Wildenhues.
1458 Reword to avoid "@code{...}'s" and the like, since it's ugly
1459 with Emacs info mode. discontents -> woes.
1460 Put a few "will"s back. time stamp -> timestamp.
1461 side-effect -> side effect.
1463 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1465 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1466 Warn about $@ not persisting. Problem reported by Julien Danjou in
1467 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1468 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1469 Mention other special chars, too.
1471 2006-06-14 Eric Blake <ebb9@byu.net>
1473 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1475 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1477 * doc/autoconf.texi: Some systematic minor improvements, as
1478 follows. Use "makefile" when talking about makefiles
1479 generally (which might be named "makefile" or "Makefile" or even
1480 "foo.mk"), "Makefile" when talking about a specific makefile
1481 called "Makefile". This unclutters the text from weird quotes
1482 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1483 values" rather than "@var{foo}s" and similar constructs containing
1484 "}s". Use "Make rules" rather than "Makefile rules". Minor
1485 English-language improvements. Change the prefix "sub-" to "sub"
1486 and "re-" to "re".
1487 Put blank lines around examples more consistently.
1488 Avoid "rather" and "very" as intensifiers.
1489 Avoid "will" as an auxiliary.
1490 (Limitations of Make): Split this node into....
1491 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1492 (Leading _ in Macro Names, Backslash-Newline-Newline):
1493 (Backslash-Newline Comments, Long Lines in Makefiles):
1494 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1495 (obj/ and Make, make -k Status, VPATH and Make):
1496 (VPATH and Double-colon, $< in Explicit Rules):
1497 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1498 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1499 New nodes, resulting from splitup of Limitations of Make.
1500 All cross-references changed. Raise the top node from
1501 a section to a chapter, and all subnodes accordingly.
1502 Redo the introductory wording to match the new organization.
1503 (Installation Directory Variables): Use an example that is
1504 closer to what Autoconf actually does. Mention that VPATH's
1505 value should not contain metacharacters or white space.
1506 (Fortran Compiler): Fix a VPATH bug in an example.
1507 (Leading _ in Macro Names): Mention that this problem is no longer
1508 of practical concern.
1509 (VPATH and Make): Reword the advice to make it clearer
1510 that Autoconf and Automake support VPATH in non-GNU make, but
1511 many packages have bugs in this area.
1512 ($< in Explicit Rules): Refer to Build Directories rather
1513 than using a (non-VPATH-safe) example.
1514 (Automatic Rule Rewriting): Mention the sort of disaster that
1515 can ensue with Solaris-style rule rewriting with VPATH.
1517 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1519 * doc/install.texi (Compilers and Options): Weaken the
1520 suggestion to use GNU make for VPATH builds.
1522 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1523 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1525 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1526 in regular expression.
1528 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1530 * doc/autoconf.texi (Installation Directory Variables):
1531 Drop extra @samp from `@table @samp' item.
1532 (Limitations of Usual Tools): Comment fix.
1533 Do not nest @samp just to point to other table items.
1534 (Writing testsuite.at) <AT_CHECK>: The second argument to
1535 `@dvar' is already @samp'ed.
1536 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1537 do not use @var in the second argument.
1539 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1541 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1542 $as_shell.exe too. Problem reported by Andreas Buening in
1543 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1545 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1547 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1548 `unused variable' compiler warning, for `-Wall -Werror'.
1549 Reported by Jaap Haitsma in
1550 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1552 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1554 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1555 case the compiler dumps core. Problem reported for
1556 OpenServer 5.0.7 by Tim Rice in
1557 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1558 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1559 Likewise.
1561 2006-06-06 Tim Rice <tim@multitalents.net>.
1563 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1564 "ERROR" only shows up in "make check" output if there is an
1565 error.
1567 2006-06-06 Eric Blake <ebb9@byu.net>
1569 * tests/tools.at (automatically allowed tokens): Fix typo.
1571 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1573 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1575 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1576 typically overflows on x86 CPUs, even though the C standard
1577 requires otherwise.
1579 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1581 * configure.ac (AC_INIT): Bump to 2.59e.
1582 * NEWS: Update.
1584 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1586 Version 2.59d.
1588 * config/texinfo.tex: Sync from upstream.
1590 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1591 seen, invoke libtoolize with `--ltdl' argument.
1592 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1593 * NEWS: Update.
1594 Suggested by Eric Blake.
1596 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1598 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1599 reported by Ralf Wildenhues.
1600 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
1602 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1604 * THANKS: Update.
1606 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1608 * doc/autoconf.texi: Modernize some of the references to Solaris.
1610 2006-06-05 Stepan Kasal <kasal@ucw.cz>
1612 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
1613 message issued by AC_REQUIRE.
1614 * tests/m4sugar.at: Check m4_require's error message.
1615 * tests/base.at: Check AC_REQUIRE's error message.
1616 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1617 to...
1618 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1619 AT_CHECK_M4.
1620 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1621 `expout' as the last parameter.
1622 * tests/tools.at: Adapt to the above change.
1624 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1626 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1627 information about race-free implementations of mkdir.
1629 2006-06-04 Eric Blake <ebb9@byu.net>
1631 * bin/autoreconf.in (help): Document M4 environment variable.
1632 * bin/autoconf.as (Usage): Likewise.
1633 * bin/autom4te.in (help): Likewise.
1634 * doc/autoconf.texi (autom4te Invocation): Likewise.
1636 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1638 * NEWS: GNU make now recommended for VPATH builds.
1639 Mention that some macros are now documented to be obsolescent.
1640 * doc/autoconf.texi:
1641 Prefer "current" to "modern" to describe
1642 currently-used (albeit perhaps old-fashioned) hosts.
1643 Mention which ancient features no longer need to be worried about.
1644 setgid -> set-group-ID
1645 setuid -> set-user-ID (these are the Posix terms)
1646 Fix some misuses of "only".
1647 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1648 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1649 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1650 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1651 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
1652 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
1653 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
1654 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1655 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1656 Mention that these macros are obsolescent.
1657 (Installation Directory Variables): shall -> should
1658 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1659 Mention that it's now safe to use 3 and 4.
1660 (Limitations of Usual Tools): cp -r is now specified by Posix.
1661 Omit longwinded and obsolescent discussion of cp -f.
1662 Modernize discussion of expr, ls.
1663 (Limitations of Make): Modernize discussion of VPATH builds.
1664 Mention $? as a workaround in some cases.
1665 * doc/install.texi (Basic Installation):
1666 Mention "./configure; make; make install" first. Be more
1667 specific about why this file is generic. Remove unnecessary
1668 parens. Remove misleading "only". Remove obsolete advice
1669 about csh. Don't say "configure" takes awhile; say it
1670 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1671 and CC=c99 rather than CC=c89, as these are blessed by current
1672 Posix. Recommend GNU make if doing a VPATH build.
1674 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1676 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1677 examples involving shell prompts.
1679 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1680 and Paul Eggert <eggert@cs.ucla.edu>
1682 * doc/autoconf.texi (Here-Documents): Add details about the
1683 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1684 use "here-documents" instead of "here documents".
1686 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1688 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1690 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1692 * doc/autoconf.texi (File System Conventions): Warn about ":"
1693 anywhere in directory names.
1695 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1697 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1698 about quoting the case statement, just in case.
1699 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1700 was fixed in ksh93g; reported by Ralf Wildenhues.
1702 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1704 * doc/autoconf.texi (System Services): Do not document
1705 overriding EXEEXT via ac_cv_exeext=ext.
1706 (Particular Programs) <AC_PROG_MKDIR_P>:
1707 Document that ${MKDIR_P} understands --.
1708 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1709 comment.
1711 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1713 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
1714 argument with leading hyphen. Problem reported by Paul Eggert.
1716 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1718 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
1719 about quoting ac_try: quote all of it, if any of it seems suspicious.
1720 This means we don't have to worry about ${ or sed any more.
1721 Also, double-quote the case statement, to work around misuses via
1722 underquoting as reported by Ralf Wildenhues in
1723 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
1724 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
1725 undocumented and dangerous macro.
1726 Problem reported by Ralf Wildenhues in
1727 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
1729 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1731 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
1732 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
1733 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
1735 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1737 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
1738 since evidently some packages rely on the old, broken behavior.
1739 Problem reported by Ralf Wildenhues in
1740 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
1741 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
1742 pre-2006-05-26 definitions, but leave in the comments that
1743 these macros are dangerous and should not be used.
1744 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
1745 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
1746 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
1747 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
1748 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
1750 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1752 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
1753 the use of 'tr', since this is our only use of 'tr'.
1755 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1756 and Paul Eggert <eggert@cs.ucla.edu>
1758 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
1759 Don't assume 'grep' works on long lines, since AIX grep doesn't.
1761 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1763 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
1764 the output file in the `${datarootdir}' test.
1766 2005-05-28 Stepan Kasal <kasal@ucw.cz>
1767 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1769 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
1770 mention of `datarootdir' in the input file(s), but literal
1771 `${datarootdir}' in the output file, and we haven't warned yet,
1772 then warn as well: the user may have (erroneously) used
1773 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
1774 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
1775 * tests/torture.at (datarootdir workaround): Extend this test.
1776 * NEWS: Update.
1778 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1779 and Paul Eggert <eggert@cs.ucla.edu>
1781 * doc/autoconf.texi (autoheader Invocation): The first argument to
1782 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
1783 alternatives and clear up the language a bit.
1785 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
1787 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
1788 ac_config_guess, ac_config_sub, ac_configure.
1789 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1790 Fix typo that prevented an unnecessary space from being removed.
1791 Problems reported by Ralf Wildenhues in:
1792 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
1794 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1796 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
1797 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
1798 Don't use the term "thread-safe" to talk about mkdir race
1799 conditions, since the problem is more a process than a thread
1800 issue. Problem reported by Stepan Kasal in:
1801 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
1802 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
1803 the test for 'install' more closely. Look at MKDIR_P first.
1804 Look in the PATH, and at /opt/sfw/bin.
1805 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
1806 Don't bother to try mkdir -p, since we already check mkdir --version;
1807 just look at the version number. (There's no easy way to check
1808 for race-free implementations.)
1809 * tests/tools.at (autoconf: subdirectories): Adjust to above
1810 changes, since MKDIR_P now might end in "/mkdir -p".
1812 * doc/autoconf.texi (autoheader Invocation): Mention that the
1813 first arg of AC_DEFINE_UNQUOTED must be a literal.
1814 Problem reported by Ben Pfaff in
1815 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
1817 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
1818 * doc/autoconf.texi (Special Chars in Variables): New section.
1819 (Preset Output Variables): Warn about special chars in CPPFLAGS.
1820 (Installation Directory Variables): Quote $(datadir) better.
1821 (Limitations of Builtins): Describe some of eval's trickiness.
1823 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
1824 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
1825 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
1826 in front of every arg, not just trailing args. Quote apostrophes.
1827 (_AC_EVAL_ECHO): New macro.
1828 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
1829 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
1830 removed.
1831 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
1832 exposed by quoting of eval argument. Put the command on line line
1833 so it logs better.
1834 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
1835 (_AC_PATH_X, AC_PATH_X): Quote more safely.
1836 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
1837 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
1838 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
1839 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
1840 Use eval more safely.
1841 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
1842 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
1843 to be replaced.
1844 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
1845 lines, exposed by quoting of eval argument.
1847 2006-05-26 Stepan Kasal <kasal@ucw.cz>
1848 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1850 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
1851 initialization of `ac_cv_exeext', do not override it if it was
1852 already set, unless it was set to `no', for compatibility with
1853 Autoconf-2.13, and comment this.
1854 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
1855 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
1856 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
1857 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
1858 Document that this test may be overridden by setting
1859 `ac_cv_exeext'.
1861 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1863 Revert these two patches:
1865 2006-04-06 Eric Blake <ebb9@byu.net>
1866 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1867 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1868 2006-04-01.
1870 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1871 Clean up _AC_COMPILER_EXEEXT* macros.
1872 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1873 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1874 ac_file to the name of the default output file and call
1875 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1876 initial `rm' of the candidate files...
1877 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1878 the same list in subsequent `rm' calls, and for the temporary
1879 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1880 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1881 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1882 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1883 no longer needed) by libtool. Make it a cache check.
1884 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1885 copied here by mistake.
1886 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1887 _AC_COMPILER_EXEEXT.
1888 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1889 _AC_COMPILER_OBJEXT directly.
1890 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1892 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1894 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
1895 Fix description of how the buggy `sed' works.
1897 2006-05-25 Noah Misch <noah@cs.caltech.edu>
1899 Sync from Automake:
1901 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
1902 ENOLCK. Only mention `make -j' when applicable. Only raise
1903 fatal errors when `make -j' is involved. Improve error message.
1905 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1907 * doc/autoconf.texi (Here-Documents): We now know more about
1908 the variable expansion in here documents bug.
1909 Thanks to Tim Rice and Stepan Kasal.
1911 * doc/autoconf.texi (Making testsuite Scripts): Add an example
1912 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
1914 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1916 * tests/autotest.at (Multiline command from M4 expansion):
1917 No failure to be expected if the shell quotes newlines in
1918 commands in the `set -x' output. Report by Tim Rice.
1919 * THANKS: Update.
1921 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1923 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
1924 expansion in the here-documents used by config.status, as that
1925 runs afoul of the Korn shell version M-12/28/93d bug described in
1926 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
1927 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
1928 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
1930 2006-05-23 Jim Meyering <jim@meyering.net>
1932 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
1933 Fix typo introduced with 2006-04-02 change. It reversed the sense
1934 of the test.
1936 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1938 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
1939 ac_dB slightly, to save bytes in the script.
1940 Max out at 50 lines, rather than 96; this is more likely
1941 (though not guaranteed) to avoid obscure 'sed' failures.
1943 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1945 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
1946 `tr -d -' as bad option argument. Work around this by deleting
1947 an unrelated character.
1948 Report by Tim Rice <tim@multitalents.net>.
1950 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
1951 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1952 Stepan Kasal <kasal@ucw.cz>
1954 * doc/autoconf.texi (Particular Programs): Do not promise that
1955 we always prefer the GNU version of the program, and that we
1956 search according to PATH; both rules can have exceptions.
1957 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
1958 AC_PROG_SED. Move descriptions of limitations
1959 to the Limitations of Usual Tools section.
1960 (Limitations of Usual Tools) <sed>: Mention script length
1961 limitations with Solaris /usr/ucb/sed.
1962 <grep>: Fix wording for empty alternative. Mention that -c and
1963 -l should not be combined, and that -E and -F should not be
1964 combined.
1966 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1967 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1969 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
1970 limits in Solaris 8 /usr/ucb/sed by testing a long script.
1972 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1974 * doc/autoconf.texi (Defining Symbols): Literal parameter of
1975 AC_DEFINE is now passed to m4_pattern_allow.
1976 * NEWS: Mention that; likewise for AC_SUBST.
1977 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
1978 the parameter to m4_pattern_allow.
1979 * tests/tools.at: Add a check for that.
1981 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1983 * lib/autoconf/status.m4: Fix typos.
1985 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1987 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
1988 only the files that this macro generates.
1990 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1992 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
1993 the HP-UX sed limitation of 99 commands, labels do not count.
1994 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
1995 in the comment.
1996 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
1998 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2000 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2001 Import the following fix from coreutils:
2003 2006-01-13 Jim Meyering <jim@meyering.net>
2005 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2006 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2007 not double-quote uses of that variable, to accommodate the rare
2008 case in which getmntent is available in none of the libraries
2009 checked. This happens at least on FreeBSD 5.0.
2011 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2013 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2014 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2015 some other programs unwisely rely on these undocumented vars.
2016 But put in warning comments about them.
2017 Problem reported by Ralf Wildenhues in
2018 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2019 * NEWS: Document that these variables are intended to go away.
2021 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2023 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2024 and set the language to C++ (analogous to the equivalent Fortran
2025 tests).
2027 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2028 * doc/autoconf.texi (C++ Compiler): Document it.
2029 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2030 * NEWS: Update.
2032 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2034 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2035 that caused config.status to generate 100-command sed scripts; the
2036 portable limit is 99.
2038 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2040 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2041 variable `ac_d' instead of `d' to avoid infringing namespace.
2042 Report by Ralf Menzel.
2044 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2046 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2047 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2048 * tests/tools.at (autoconf: subdirectories): New test, taken from
2049 the corresponding problem report by Ralf Wildenhues in:
2050 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2052 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2053 Quote some uses of shell variables if they might suffer unexpected
2054 globbing. This doesn't fix all instances of quoting problems that
2055 I found, just the easy ones that look safe.
2056 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2057 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2058 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2059 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2060 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2061 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2062 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2063 Likewise.
2064 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2065 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2067 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2069 * bin/autoreconf.in ($help): Reword according to the manual.
2070 Suggested by Olly Betts.
2072 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2073 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2075 * bin/autoreconf.in: Pass the directory argument to
2076 `require_configure_ac'. Fix comment.
2077 * tests/torture.at (Configuring subdirectories): Expose this.
2078 Reported by Olly Betts.
2080 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2082 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2083 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2084 Automake as follows:
2086 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2087 `$configure_in' instead of `configure.in', to preserve
2088 directory component.
2090 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2092 * config/config.guess, config/config.sub, config/texinfo.tex,
2093 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2095 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2097 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2098 test for C99 conformance; (bool) 0.5 is an integer constant
2099 expression, but (bool) -0.5 is not. Problem reported by Fedor
2100 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2102 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2104 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2105 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2106 Warn about obsolete install-sh files. Remove stray sentence
2107 fragment and fix cross reference.
2108 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2109 install -d; this undoes the 2006-05-10 change.
2110 (MKDIR_P): Mark with AN_MAKEVAR.
2111 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2112 that we don't require $INSTALL to be thread-safe. Move comments
2113 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2114 of AC_PROG_INSTALL. Output a message saying that we're checking
2115 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2116 MKDIR_P instead of AC_SUBST.
2117 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2118 Special magic for MKDIR_P, too.
2119 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2120 a dnl.
2121 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2123 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2125 Sync from Automake, as follows:
2127 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2128 * config/install-sh: Initialize IFS, so field splitting isn't
2129 turned off later.
2130 * config/mkinstalldirs: Likewise.
2131 * config/missing: Remove superfluous quotes. Replace all uses of
2132 `[' by `test', for consistency, and for..
2133 * config/missing (sed_minuso, sed_output): New variables.
2134 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2135 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2136 Fixes `missing' to detect `--output' for help2man. Fixes
2137 PR automake/483. Report by Dennis J. Linse.
2138 (autom4te): Document in `missing --help'.
2140 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2142 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2143 * config/install-sh: Don't use 'path' to talk about file names,
2144 as per GNU coding standards. Close a race condition reported by Ralf
2145 Wildenhues and Stepan Kasal. There is still a race condition
2146 on hosts that predate Posix 1003.1-1992, but we can't help this.
2147 Don't mishandle weird characters like space on pre-Posix hosts.
2148 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2149 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2150 AC_PROG_MKDIR_P from AS_MKDIR_P.
2151 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2152 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2153 earlier editions are not (including Automake 1.8.3).
2154 Do not suggest mkinstalldirs for thread-safety.
2155 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2156 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2157 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2158 presence of special characters and race conditions.
2159 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2160 in Autoconf's name space.
2162 2006-05-10 Bruno Haible <bruno@clisp.org>
2163 and Paul Eggert <eggert@cs.ucla.edu>
2165 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2166 from Automake with minor changes.
2167 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2169 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2171 * config/install-sh: Update to Automake CVS version, as follows:
2172 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2173 * lib/install-sh: Simplify the expr implementation of dirname.
2174 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2175 * lib/install-sh: Handle --, and diagnose unknown options.
2177 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2179 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2180 `./autom4te' to create `./testsuite', since the `all' target
2181 will ensure its presence, but `installcheck' should not create
2182 the uninstalled wrappers.
2184 * tests/torture.at (Unusual Automake input files): Skip if we
2185 detect automake < 1.8.
2187 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2189 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2190 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2191 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2192 * NEWS: Update.
2194 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2196 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2197 munge (multiple) white space and other oddities.
2198 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2199 single quotes in variable assignment.
2200 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2201 and similar failures by adding multiple spaces, tabs, and other
2202 special characters.
2203 Report and different test suggested by Francesco Romani
2204 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2206 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2207 single quotes, we only need to search for single quotes; this
2208 both simplifies the search pattern, and makes us less
2209 susceptible to `echo' variations for arguments not containing
2210 single quotes.
2211 (_AC_ARG_VAR_VALIDATE): Likewise.
2213 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2215 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2216 `$*' and IFS concatenation issue with traditional shells and
2217 bash-2.04. Report by Seanster@Seanster.com.
2219 2006-05-03 Bruno Haible <bruno@clisp.org>
2221 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2222 precisely which Mac OS X versions have the od problem.
2224 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2226 * doc/autoconf.texi: Use @option systematically.
2228 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2229 and Bruno Haible <bruno@clisp.org>
2231 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2232 about 'od'.
2233 (Integer Overflow): Mention the special case of integer division
2234 overflow.
2236 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2238 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2239 traditional shells like the Solaris one that do not use the
2240 first IFS character for assembling `$*'.
2241 Prompted by a related report from autoconf_bug@nro.ca.
2243 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2244 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2246 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2247 Mention more problems with the -e option.
2249 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2251 * NEWS: Typo.
2252 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2254 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2255 in URLs to improve DVI formatted output (requires texinfo 4.6).
2256 (System Services, Systemology, Shellology): Likewise.
2257 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2258 output.

2264 (Obsolete Macros): Likewise.
2265 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2266 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2267 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2269 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2271 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2273 * ChangeLog: Typo.

2280 /bin/sh set unsorted output.
2281 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
2282 * tests/local.at: Likewise.
2284 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
2286 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2287 (Integer Overflow, Null Pointers, Buffer Overruns):
2288 (Floating Point Portability, Exiting Portably): New sections.
2289 (Writing Test Programs): Fix some langauge. Recommend exiting
2290 with status 1, not merely nonzero. Clarify exit declaration.
2291 (Run Time): Move C exit status stuff to new Exiting Portably section.
2292 (Systemology): Mention Posix and levenez. Update v7 reference.
2293 (Portable Shell): Mention the Posix shell.
2295 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2297 * bin/autoconf.as (me): Replace by as_me.
2299 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2301 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2302 since as_me isn't set yet.
2304 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2306 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2307 a few minor bugs in this area.
2309 * doc/autoconf.texi (Programming in M4sh): Comment out the
2310 documentation of AS_BASENAME, for now.
2311 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2312 (Limitations of Builtins) <basename>: Do not refer to
2313 AS_BASENAME.
2314 * bin/autoconf.as (me): Don't use AS_BASENAME.
2315 (dir): Remove the unused variable.
2316 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2317 AS_DETECT_REQUIRED. All uses changed.
2318 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
2319 All uses changed.
2320 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
2321 (AS_BASENAME): Use "basename --" to protect against leading "-".
2322 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
2323 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2324 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".

2330 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2332 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2333 of "run time" and "run-time" changed to "runtime", for consistency.
2334 * lib/autoconf/fortran.m4: Likewise (in comment).
2335 * lib/autoconf/functions.m4: Likewise.
2336 * lib/autoconf/general.m4: Likewise.
2337 * lib/autoconf/headers.m4: Likewise.
2339 * doc/autoconf.texi (Run Time): Document the exit status situation
2340 with more accuracy and detail.
2342 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2344 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2345 Archive is not officially `GNU' any more. Update URL.
2346 (Defining Directories): Likewise
2347 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2349 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2351 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2352 newline from the `trap' code to finish `config.log'; the NetBSD
2353 /bin/sh resets the exit status after an empty command, as
2354 documented in doc/autoconf.texi.
2355 Reported by Dalibor Topic <robilad@kaffe.org>.
2357 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2359 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2360 Suggested by Bruno Haible.
2362 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2364 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2365 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2366 Instead, just list the shells that we know work.
2367 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2368 changed. Be more cautious about the _cv_ variable.
2369 * tests/tools.at (Syntax of the shell scripts): Check the
2370 _cv_ variable once, at first, to avoid an internal autoconf error
2371 when sh -n does not work.
2373 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2375 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2377 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2379 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2380 use ">&-" since we're only 99.999% sure that this is portable,
2381 and since the MinGW bug is fixed in a different way.
2382 * lib/autotest/general.m4 (AT_INIT): Likewise.
2384 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2386 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2387 before opening config.log, to avoid hitting a bug on MinGW.
2389 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2391 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2392 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2393 This works around a MinGW bug reported by Eric Paire.
2394 Make sure that all writes to the log file append to it,
2395 rather than possibly losing data.
2396 * lib/autotest/general.m4 (AT_INIT): Likewise.
2398 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2400 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2401 description.
2403 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2405 * NEWS: Update.
2407 * configure.ac (AC_INIT): Bump to 2.59d.
2409 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2411 Version 2.59c.
2413 * Makefile.maint (news-date-check): Do not require a leading `*'
2414 before the release date in NEWS.
2416 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2417 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2419 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2420 the instantiated file do not contain the string 'datarootdir'
2421 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2422 @mandir@, replace the reference '${datarootdir}' by the value.
2423 * tests/torture.at (datarootdir workaround): New test.
2424 * NEWS: Advertise this temporary fixup.
2425 Based on a patch by Bruno Haible, reported and analyzed by
2426 Paul Eggert and Noah Misch.
2428 2006-04-12 Eric Blake <ebb9@byu.net>
2430 * tests/autotest.at (Debugging a failed test): Fix comment.
2432 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2434 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2435 all the changes since 2006-04-07.
2437 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2439 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2440 succeeded, but `ln -s file dir' failed, take care to remove the
2441 leftover target before the next test, to prevent its spurious
2442 failure; also make sure `ln file dir' works before selecting it.
2443 Thanks to Keith Marshall for pointing this out.
2444 * THANKS: Update.
2446 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2447 assignments in `at_debug_args', so that we put them correctly
2448 in the `run' script.
2449 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2450 Reported by Eric Blake.
2452 2006-04-11 Eric Blake <ebb9@byu.net>
2454 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2455 top-level tests after micro-suite has been run. Used in...
2456 (Debugging a successful test, Debugging script and environment),
2457 (Debugging a failed test): ...these new tests. The first of these
2458 is fixed by...
2459 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2460 macro, split out from...
2461 (AT_INIT): ...here, so that using -d also generates a run script.
2462 Document that -d inhibits top-level logging.
2463 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2464 inhibits top-level logging; debug scripts are created.
2466 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2467 check.
2468 * tests/autotest.at (Empty test, Empty check): New test to check it.
2470 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2471 from gcc.
2473 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2475 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2476 the files if a problem appears. Make the empty *.at files
2477 read-only, too. Proposed by Ralf Wildenhues.
2479 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2481 * config/Makefile.am: Add comment to force updated Makefile.in.
2483 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2484 space only patch to this file, this patch causes the Makefile.in
2485 files that include freeze.mk to be updated, and thus have a
2486 newer time stamp again, which in turn makes a pristine CVS
2487 checkout have correct time stamps.
2489 * Makefile.maint (cvs-sv): New macro, to be used..
2490 (config.guess-url_prefix, config.sub-url_prefix)
2491 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2492 point to CVS text checkout of Gnulib files.
2493 (copyright-check): Bump current year.
2494 (announcement): Do not hard-wire `./announce-gen'.
2495 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2496 correctly.
2497 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2498 `chmod +x'.
2499 (wget_files): Update config.guess, config.sub, texinfo.tex by
2500 `wget-update', now that their URLs work again.
2502 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2504 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2505 Problem noted by Paul D. Smith.
2507 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2509 * doc/autoconf.texi: Remove unused words from word list.
2510 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2511 .x-sc_trailing_space: New files.
2513 * doc/standards.texi: Sync from gnulib.
2515 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2516 `LIBOBJDIR' as experimental.
2518 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2519 with a target directory; it's internally implemented as `cp'
2520 anyway, but since Autoconf advertises the possibility to use
2521 a target directory when LN_S is `ln -s', we need to find out.
2522 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2523 analyzed by Keith Marshall <keith.marshall@total.com>.
2525 * THANKS: Update.
2527 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2529 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2530 confdefs.h as-is. In general, if it has backslash-newline or the
2531 like, then it doesn't work either to sort or to remove empty
2532 lines.
2534 2006-04-09 Stepan Kasal <kasal@ucw.cz>
2536 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
2538 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
2540 * lib/autom4te.in (Automake-preselections): Preselect
2541 _AM_SUBST_NOTMAKE.
2543 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2545 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2546 apostrophe within a single-quoted string, as this is the usual
2547 tradition and is easier to read than '"'"'. Don't rely on the
2548 shell treating "$/" like '$/'. Use a more-consistent indenting
2549 style for the trap.
2551 2006-04-09 Eric Blake <ebb9@byu.net>
2553 * tests/autotest.at (Backquote command substitution),
2554 (Multiline backquote command substitution): Remove mistaken
2555 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2556 applied...
2557 (Parenthetical command substitution, Multiline parenthetical
2558 command substitution): here.
2560 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2562 Import macros from gnulib (often changing their name).
2564 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

2576 (Pointers): Add Gnulib URL.
2577 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
2578 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
2579 Gnulib section.
2580 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
2581 suggest a #define rather than a typedef for _Bool, and mention
2582 Gnulib rather than trying to substitute stdbool code.
2583 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
2584 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
2585 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
2586 AC_STRUCT_DIRENT_D_TYPE.
2587 (Particular Types): Mention stdint.h and inttypes.h as standard
2588 headers too.
2589 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
2590 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
2591 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
2592 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
2593 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
2594 (C Compiler): Move AC_C_LONG_DOUBLE to ...
2595 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
2596 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
2597 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
2598 (Coding Style). Don't mention m4_expand_once.
2599 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
2600 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
2601 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
2602 (AC_CHECK_FUNCS): Use it.
2603 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
2604 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
2605 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
2606 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
2607 (AC_HEADER_ASSERT): New macro.
2608 (AC_HEADER_STDBOOL): Don't assume "#error" works.
2609 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
2610 Catch a bug in an HP-UX C compiler.
2611 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
2612 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
2613 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):

2615 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
2616 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
2617 New macros.
2619 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
2620 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
2622 2006-04-08 Stepan Kasal <kasal@ucw.cz>
2624 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
2625 of the warning introduced by the 2001-08-28 change.
2627 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
2628 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2630 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
2631 variables shall be overriden by the cache.
2632 * tests/torture.at (AC_ARG_VAR): Test also with a first value
2633 that contains braces.
2635 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2637 Revert the patch from 2006-04-01 and only improve
2638 _AS_DETECT_BETTER_SHELL:
2640 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2641 skip nonexistent directories.
2642 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2643 only shell candidates which exist.
2644 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2645 * lib/autotest/general.m4 (AT_INIT): No need to give three
2646 parameters to _AS_PATH_WALK.
2648 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2649 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2651 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2652 distinguish m4sugar macros.
2653 * tests/tools.at (autoupdating with aclocal and m4_include):
2654 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2655 test case by Noah Misch <noah@cs.caltech.edu>.
2657 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2659 Revert my change from 2006-03-17, in other words:
2660 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
2661 and DUALCASE=1.
2662 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
2663 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
2664 it is set.
2666 2006-04-07 Eric Blake <ebb9@byu.net>
2668 * doc/autoconf.texi (Programming in M4sh): Document that
2669 AS_MKDIR_P exits the script on failure.
2670 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2672 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2674 * config/elisp-comp, config/install-sh, config/mdate-sh,
2675 config/missing, config/mkinstalldirs: Sync from Automake.
2677 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
2678 from Automake.
2680 * doc/make-stds.texi: Sync from gnulib.
2682 2006-04-06 Eric Blake <ebb9@byu.net>
2684 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2685 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2686 2006-04-01.
2688 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
2689 Eric Blake <ebb9@byu.net>,
2690 Paul Eggert <eggert@cs.ucla.edu>,
2691 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2693 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2694 whether `set' quotes correctly: redirect stderr of the tested
2695 `set', and use a subshell, for Ultrix; use `sed' instead of
2696 `grep' for zsh `set' which may write binary output; match only
2697 at the beginning of a line, to avoid false positives.
2698 In order to avoid false positives by unrelated variables with
2699 multiline content, put the dump algorithm in a subshell and
2700 unset all variables containing newlines (except some which are
2701 special to the shell). Warn about cache variables that are

2905 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2906 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set

2908 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2909 initial `rm' of the candidate files...
2910 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2911 the same list in subsequent `rm' calls, and for the temporary

2914 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2915 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2916 no longer needed) by libtool. Make it a cache check.
2917 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2918 copied here by mistake.
2919 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2920 _AC_COMPILER_EXEEXT.

2958 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
2959 * doc/autoconf.texi (autoreconf Invocation): Document it.
2961 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

3620 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
3621 Fix quoting of output line (triggered for many AC_SUBST_FILEs).
3622 Fix macro quoting. Fix output for n * 98 substituted variables.
3624 2005-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3626 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Initialize
3627 `tmp' to avoid file removal race.
3629 2005-11-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3631 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
3632 ac_clean_files and LIBOBJS.
3634 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3636 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
3637 Factor functionality to..
3638 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
3639 `AC_SUBST($1)' in the public version.
3640 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
3641 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
3642 ac_pt_* variables.
3644 2005-11-01 Stepan Kasal <kasal@ucw.cz>
3646 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
3647 filesystems.
3649 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3651 * NEWS: Move AH_HEADER mention to right place.
3653 2005-10-27 Stepan Kasal <kasal@ucw.cz>
3655 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
3656 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3658 2005-10-25 Stepan Kasal <kasal@ucw.cz>
3660 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
3661 conftst2.$ac_objext.
3662 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3664 2005-10-24 Stepan Kasal <kasal@ucw.cz>
3666 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
3667 conftest.o, to see whether the compiler really obeys; rm the object
3668 file before and after the test and register it with ac_clean_files.
3669 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3671 2005-10-21 Stepan Kasal <kasal@ucw.cz>
3673 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
3674 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
3675 code so that the most common case requires less forks.
3677 2005-10-20 Stepan Kasal <kasal@ucw.cz>
3679 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
3680 not portable; thanks to Paul Eggert and Alexandre.
3682 * NEWS: Fix an old typo.
3684 2005-10-20 Jim Meyering <jim@meyering.net>
3686 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
3687 the latter'', in two places.
3689 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
3691 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
3692 AC_LANG_PROGRAM, fixing a typo. Don't give details about
3693 the inner workings of AC_LANG_FUNC_LINK_TRY.
3694 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
3695 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
3696 by the function rather than ignoring it.
3697 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
3698 comparing its address. Intel's interprocedural optimization was
3699 outsmarting the old heuristic. Problem reported by
3700 Mikulas Patocka.
3702 2005-10-19 Stepan Kasal <kasal@ucw.cz>
3704 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
3706 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
3708 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

3711 2005-10-04 Stepan Kasal <kasal@ucw.cz>
3713 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
3714 before removing it (chmod -R u+rwx); there are three instances of this.
3716 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3717 Stepan Kasal <kasal@ucw.cz>
3719 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
3720 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
3721 make its content writable before removing it. Remove an errorneous
3722 comment from the end, where the logs of the failed tests are copied
3723 to the main log file.
3725 2005-09-27 Stepan Kasal <kasal@ucw.cz>
3727 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
3728 in case the computer is too quick. Double quote the configure.ac
3729 snippets.
3731 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
3732 problems if the testsuite were running too fast.
3734 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3736 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3737 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3738 (which belong to Xt, not X itself). See Debian bug 327655.
3739 * NEWS: Mention this.
3741 2005-09-07 Stepan Kasal <kasal@ucw.cz>
3743 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
3745 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
3747 * config/move-if-change: Don't output "$2 is unchanged";
3748 suggested by Ben Elliston. Handle weird characters correctly.
3750 2005-09-06 Stepan Kasal <kasal@ucw.cz>
3752 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
3753 calls, so that the final expansion of this macro is shorter.
3754 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
3755 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
3756 the cleanup there. Use AS_VAR_* macros, to be more general.
3757 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
3759 * lib/autoconf/general.m4: Use AS_IF where appropriate.
3761 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
3763 2005-09-01 Stepan Kasal <kasal@ucw.cz>
3765 * doc/autoconf.texi (Configuration Headers): Add an index entry
3766 for AH_HEADER.
3768 2005-08-26 Pavel Roskin <proski@gnu.org>
3770 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
3771 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
3772 running xmkmf.
3774 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
3776 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3777 The previous patch didn't work, so try a better one.
3779 2005-08-26 Stepan Kasal <kasal@ucw.cz>
3781 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
3782 in the example. Reported by Bruno Haible.
3783 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
3784 "if $undefined_var;" succeeds with my shell.
3786 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
3787 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
3788 but change the m4_divert_text to m4_divert_once.
3790 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
3792 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3793 Work around bug in Solaris /usr/xpg4/bin/awk.
3794 The bug is present in at least Solaris 8 through 10.
3796 2005-08-24 Stepan Kasal <kasal@ucw.cz>
3798 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
3799 some evil values and relying on the fact that $* concatenates the
3800 parameters by the first character from IFS.
3802 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3803 Stepan Kasal <kasal@ucw.cz>
3805 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
3806 first header appears, define AH_HEADER.
3807 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
3808 Update limitations about when to call AC_CONFIG_HEADERS.
3809 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
3810 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
3811 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
3812 ``Configuration Actions''; fix their index entries.
3814 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
3815 options correctly. Process N-M as M-N if M is smaller than N.
3816 Process ranges correctly so that N-N will run only N.
3817 Sort and uniquify the tests that will be run. If there is more
3818 than one test, reinsert the banners for the tests.
3819 * tests/autotest.at (Keywords): Unmark XFAIL.
3821 2005-08-23 Stepan Kasal <kasal@ucw.cz>
3823 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
3824 before passing the macro name to AH_TEMPLATE.
3826 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
3827 now opens log after option processing; in particular, --version
3828 and --help do not touch config.log.
3830 * Makefile.maint: Revert the change from 2005-08-12.
3832 2005-08-22 Stepan Kasal <kasal@ucw.cz>
3834 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
3835 common code to...

3838 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3840 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
3841 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
3842 Language cleanup.
3844 * doc/autoconf.texi (Defining Symbols, Changed Results):
3845 Prepend to LIBS, not append, in examples.
3847 2005-08-16 Stepan Kasal <kasal@ucw.cz>
3849 When building in place, set srcdir="."; suggested by Tim Van Holder.
3851 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
3852 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
3853 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
3854 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
3855 does not mean "no --srcdir option".
3857 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3859 * tests/autoscan.at (autoscan): New file.
3860 * tests/suite.at: Use it.
3861 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
3862 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
3864 * tests/autotest.at (Keywords): Test keywords combinations.
3866 2005-08-12 Stepan Kasal <kasal@ucw.cz>
3868 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
3869 add "2>&1"; gzip 1.2.4 prints help on stderr.
3871 2005-07-27 Stepan Kasal <kasal@ucw.cz>
3873 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
3874 was pushdef'ed twice while popped only once. Push it only once.
3875 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
3877 2005-07-26 Stepan Kasal <kasal@ucw.cz>
3879 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
3880 prefixed by mere "===", not "configure: === ".

3884 * Makefile.maint: Update from Bison.
3886 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
3887 "<tab>" in comment, so that the point is understandable.
3889 2005-07-25 Stepan Kasal <kasal@ucw.cz>
3891 Rewrite substantial part of lib/autoconf/status.m4.
3892 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
3893 and CONFIG_COMMANDS are not processed in four separate loops.
3894 Instead, there is one main loop. This alows that the common code
3895 is expanded only once, thus config.status (and configure) is smaller.
3897 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
3898 the AC_LIST_FILES and cousins macros are no longer used.
3900 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
3901 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
3902 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
3903 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
3904 contain the initialization, nor the for loop, nor the associated
3905 commands; all these go to ...
3906 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
3907 _AC_OUTPUT_CONFIG_STATUS.
3908 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
3909 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
3910 (_AC_OUTPUT_FILE): The creation of the sed script ...
3911 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
3912 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
3913 _AC_OUTPUT_MAIN_LOOP.
3914 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
3915 _AC_CONFIG_COMMANDS): Use ...
3916 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
3917 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
3918 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
3919 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
3920 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
3921 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
3922 ... new macros.
3923 (_AC_CONFIG_UNIQUE): Update.
3924 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
3925 Replaced by this ...
3926 (_AC_LIST_TAGS): ... new common macro.
3927 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
3928 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
3929 (_AC_LIST_TAG_COMMANDS): ... new common macro.
3930 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
3931 this didn't belong to the `config commands' section.
3932 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
3933 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
3934 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
3935 to the `config commands' section either.
3936 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
3937 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
3939 ... and many changes to the comments nearby.
3941 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
3942 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
3943 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
3944 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
3945 (#define header templates): The comment at the top of the generated
3946 header now includes the name(s) of the source file(s).
3948 Several unrelated small changes:
3950 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
3951 parameter to AC_DIAGNOSE.
3952 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
3953 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
3954 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
3955 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
3956 with AU::AC_OUTPUT.
3957 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
3958 in AC_OUTPUT doesn't double-quote it either.
3959 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
3960 parameters.
3962 2005-07-10 Stepan Kasal <kasal@ucw.cz>
3964 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
3965 versions of Portland Group compiler produce single- and double-quoted
3966 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
3967 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
3969 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3971 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3972 This is a corrected version of yesterday's patch.
3974 2005-07-07 Stepan Kasal <kasal@ucw.cz>
3976 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
3977 path, too; insert a "===" to emphasize the line.
3979 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
3980 ac_cv_build_alias to ac_build_alias.
3981 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
3983 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
3984 change eliminates it. Problem reported by Alexandre Duret-Lutz.
3985 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
3986 (AC_ARG_VAR): ... here.
3987 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
3988 target_alias.
3990 Keep a list of all precious variables and process them with one simple
3991 for loop, instead of expanding all commands, or, OTOH, complicated
3992 processing of output of "set".
3993 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
3994 variable names in new macro...
3995 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
3996 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
3997 a loop to assign all ac_env_* and ac_cv_env_* variables.
3998 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
3999 to INIT_PREPARE.
4000 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4001 its value to shell variable ac_precious_vars and call
4002 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
4003 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
4004 _AC_ARG_VAR_VALIDATE.
4006 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
4007 and the AC_SUBSTs ...
4008 (AC_INIT): ... here.
4010 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
4011 the ac_subst_files section in config.log.
4013 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
4015 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

4019 * lib/autoconf/c.m4 (AC_C_TYPEOF): New macro.
4020 * tests/c.at (C keywords): Test AC_C_TYPEOF.
4022 Fix problems reported by Nicolas Joly.
4023 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
4024 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4025 They are generated by the Tru64 v5.1B shell.
4027 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4029 Fix my changes from 2005-07-01; reported by Noah Misch.
4030 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
4031 description, the macro now accepts only a single tag.
4032 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
4034 Fix cases when the varsions of Autoconf and Autotest don't match.
4035 Reported by Noah Misch.
4036 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
4037 at_top_builddir, for compatibility with older autotest.
4038 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
4039 is not set, use at_top_builddir, for compatibility with older
4040 versions of autoconf.
4042 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4044 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
4045 Problem reported by Patrick Welche.
4047 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4049 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4050 sed substitution command, so that we allow | in program prefixes
4051 and program suffixes. (& is a problem anyway; we're not fixing
4052 that here.)
4053 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4054 configure_input, top_builddir, srcdir, etc.
4055 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4056 PATH_SEPARATOR in AUTOTEST_PATH.
4058 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
4060 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
4061 for loop over config.site files using `set', to allow
4062 directory names containing IFS characters.
4064 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
4066 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
4067 directories with weird names. Apparently some people like living
4068 on the edge. However, improve the test that "pwd" actually does
4069 report a name for the working directory.

4086 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
4088 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
4089 document to output the default config_* lists to config.status.
4090 Don't recognize option --file, if the functionality is not there.
4091 Likewise for --header; moreover, recognize --he and --h as shortcuts
4092 for --help in that case.
4094 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4095 matches the order of execution. No code changed.

4118 (AC_SUBST): Call it.
4119 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4120 the directory specific variables; but don't call it for configure_input.
4122 2005-06-28 Derek Price <derek@ximbiot.com>
4124 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4125 addition.
4127 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4129 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4130 directory have inherent problems with special characters like spaces,
4131 due to limitations in Make syntax. Problem reported by Alexandre
4132 Duret-Lutz.
4133 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

4146 from Justace Clutter.
4147 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4148 variable into diagnostic. Make the diagnostic an error, not a warning,
4149 because we really don't support spaces and suchlike in dir names.
4150 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4151 Don't worry about backslashes in srcdir; it can't happen now.

4178 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4179 b, t, r, w commands require single space, while : cannot have any.
4180 (Special Shell Variables): Fix sed code this in the example.
4181 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4182 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4184 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4185 expand to the empty list. Don't use two pairs of m4_changequote,
4186 it's not necessary.
4188 2005-06-20 Derek Price <derek@ximbiot.com>
4190 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.

4194 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4195 * doc/autoconf.texi:
4196 Don't mention Solaris versions so much, if a
4197 problem is common to all extant versions of Solaris. Say "SunOS
4198 4" instead of "SunOS" for SunOS 4.
4199 (awk): Mention more of the limitations of traditional Awk.
4200 (cat): Don't talk about cat -v.
4202 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
4204 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
4205 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

4207 to be compatible with glibc strverscmp.
4208 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4210 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4211 on Mac OS X 10.4 reported by Peter O'Gorman in:

4216 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4218 * doc/autoconf.texi: "filesystem" -> "file system".
4219 "behaviour" -> "behavior".

4222 as per POSIX.
4223 * lib/m4sugar/m4sh.m4: Likewise.
4224 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
4225 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
4227 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4228 (.x.1): Ignore the time stamp in the .TH line when deciding whether

4238 AS_TR_SH.
4240 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
4242 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4243 -u, since it outputs chatter if the input files are the same.
4244 Problem reported by Ralf Menzel.
4246 2005-06-08 Derek Price <derek@ximbiot.com>
4248 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4249 renaming them since they are about to be redefined anyhow.
4251 2005-06-08 Derek Price <derek@ximbiot.com>
4253 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4254 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4255 Move m4_undefine to alphabetical order.
4257 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4259 * README: Recommend GNU M4 1.4.3 or later.
4260 * doc/autoconf.texi (Introduction): Likewise.
4261 Reword to avoid some formatting glitches.
4262 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4263 Clarify explanation of HP compiler bug.
4264 Redo example output tp match current CVS snapshot.
4265 Use @example.org in email addresses when the examples
4266 might get inadvertently cut-and-pasted into user code.
4267 Remove example of autom4te usage that doesn't seem to work now.
4268 Use modern AC_INIT (except when the example is meant to be
4269 shown with Autoconf 2.13).
4270 Update ksh info for Solaris 9 and later.
4271 KB -> kB.
4272 Modernize description of Automake versions a bit.
4273 Don't claim a future version of Autoconf is near.
4274 * doc/install.texi: Reword to avoid some formatting glitches.
4276 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4279 follows its own advice about quoting better.
4280 Reword to avoid some formatting glitches.
4281 * doc/installt.exi: Reword to avoid some formatting glitches.
4283 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4284 Tru64 ksh pattern matching bug. Reported against Libtool by
4285 Albert Chin <libtool@mlists.thewrittenword.com> and
4286 Nicolas Joly <njoly@pasteur.fr>.
4288 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4290 m4_cdr of one-member list was [[]] (one-member list containing an
4291 empty string) instead of [] (an empty list. Callers were skewed to
4292 match this misbehaviour. As a consequence of this:
4293 - m4_foreach([x], [], [foo]) expanded to `foo', while
4294 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4295 This bug has been fixed:
4297 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4298 expand to an empty string; print error msg if called without
4299 an argument list.
4300 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4301 misbehaviour; handle [] and [[]] correctly.
4303 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4305 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

4307 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4309 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4311 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4312 swallow records with more than 99 fields.
4313 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4314 parse the long line.
4316 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4318 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4319 swallow literals longer than 399. Reported by Ralf Wildenhues.
4320 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4321 to workaround this limitation.
4323 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4325 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4326 to gfortran, and make these the first two compiler names
4327 checked (following the general autoconf preference for gcc).
4329 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4331 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4332 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4333 (testsuite): Make sure autotest.m4f is up-to-date before using it.
4335 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
4337 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4338 expression of unbounded size when processing the --list
4339 option. This runs afoul of a limit of 399 bytes per regular
4340 expression on AIX. Problem reported by Ralf Wildenhues.
4342 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

4345 * doc/autoconf.texi (Particular Headers): Reword example
4346 for multiline stdbool replacement.
4347 (Setting Output Variables): Reword text a bit. Don't
4348 give all the details about |#_!!_#|.
4349 Reword description of line replacement.
4351 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4353 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4354 now contain newlines, and substituted files must be referenced on
4355 a line alone; the sed scripts to substitute them are now very
4356 different.
4357 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4358 commands can be put in a sed script portably.
4359 * doc/autoconf.texi (Setting Output Variables): Document above
4360 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4361 use of multiline substitution.

4371 * tests/local.at: Don't attempt to check for negated character
4372 classes in shell scripts. The test was too brittle.
4374 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4376 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4377 * doc/autoconf.texi (Limitations of Builtins): Document this
4378 limitation.
4380 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4382 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4383 common code; used in many places in the tree.

4390 messages when ac_unique_file is not found.
4391 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4392 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4393 commands, for consistency with AC_MSG_ERROR and such.
4395 * bin/autoconf.as: Make more use of "shift 2" in option processing.

4405 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4407 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4408 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4409 (ac_top_builddir): ... this ...
4410 (ac_top_build_prefix): ... to this; the old name is also kept, for
4411 backward compatibility.
4412 (ac_top_builddir_sub): New variable, without the trailing slash,
4413 always nonempty.
4414 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4415 * doc/autoconf.texi (Configuration Actions): Rename
4416 ac_top_builddir to ac_top_build_prefix.

4426 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4428 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4429 argument to m4_foreach. I guess it was necessary in the past,
4430 but I think it's a no-op now.
4432 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4434 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4435 ``cat <<_ACEOF'' commands to one.
4436 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4437 * lib/autoconf/status.m4: On various places, use expr instead of
4438 ``echo|sed.''
4439 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4440 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4441 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4442 a range.
4443 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
4444 the wrong patterns between ``case'' and ``esac.'' The previous
4445 code had false positives.
4447 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4449 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
4450 as on 2005-05-02.
4451 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
4452 Mention LIBOBJDIR.

4516 "blank", "white space", and "space" all have different meanings
4517 and we should be careful to say what we mean.

4537 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
4538 set by latest automake.
4540 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
4542 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
4543 outputs 0 on GNU/Linux these days.
4545 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
4547 * doc/autoconf.texi (Autoconf Language): Add more description
4548 about quoting heuristics.
4549 (Limitations of Builtins): Describe "set -" problems.
4551 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4553 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
4554 not newline.
4556 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
4557 by AC_DEFINE; it was a mistake.
4558 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
4560 2005-04-25 Stepan Kasal <kasal@ucw.cz>
4562 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
4564 2005-04-22 Stepan Kasal <kasal@ucw.cz>
4566 * doc/autoconf.texi (External Software): Quadrigraphs are not
4567 processed correctly in AS_HELP_STRING; avoid this in the examples.
4568 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4569 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
4570 comment and reduce m4_default([foo], []) to [foo].
4571 (m4_strip): Update the explanation.
4573 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4575 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
4576 Remove core.conftest.* too; it's generated by Tru64 5.1.
4577 Problem reported by Jennis Pruett.
4578 * lib/autoconf/functions.m4
4579 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4580 Don't bother to remove core files; AC_RUN_IFELSE should do that
4581 for you.

4625 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4627 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
4628 Merge `-z option' as well for the benefit of Solaris link flags. Pass
4629 whole-archive (-zallextract, -zdefaultextract) options in the hope of
4630 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
4631 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
4633 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
4635 * NEWS: The configure command now warns you if you attempt to use
4636 a directory whose name contains a special character like space,
4637 newline, or "\".
4638 * doc/autoconf.texi (Installation Directory Variables): Allow
4639 "," in file names. Do not use \@; it's not a portable regexp.
4640 * bin/Makefile.am (edit): Likewise.
4641 * lib/Makefile.am (edit): Likewise.
4642 * tests/Makefile.am (edit): Likewise.
4643 * tests/semantics.at: Likewise.

4646 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
4647 * doc/autoconf.texi (File System Conventions): Warn about
4648 unportable file names.
4649 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4650 (AC_INIT): Use it.
4651 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4652 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4653 ac_pwd, and quote srcdir.
4654 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4656 * doc/autoconf.texi: Fix some systematic formatting problems.
4657 ".)" needs a following @: if not at the end of a sentence, and
4658 similarly for "!)". "etc." should be preceded by a comma.
4659 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4661 2005-03-22 Bruno Haible <bruno@clisp.org>
4663 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4664 argument is often called 'build-aux'.
4666 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4668 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4669 macro AC_TRY_LINK is obsolete.
4670 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4671 `AC_CONFIG_FILES'.
4673 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4675 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4676 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4677 from a Common Lisp's `cl'.
4678 (AC_PROG_CXX): Behave according to the documentation: don't
4679 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4680 make the variable CCC precious; use `cl.exe', not `cl'.
4682 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4683 Alexandre Duret-Lutz <adl@gnu.org>
4685 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4686 /dev/null, as "configure" shouldn't read stdin, and this insulates
4687 us from problems (e.g., when testing for "cl"). Also, do this
4688 redirection before invoking "hostname" or "uname", and keep the
4689 original input stream available via...
4690 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4691 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4692 bother with "</dev/null" since it's now done at the top of
4693 'configure'.
4694 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4695 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

4699 * tests/base.at (Input/Output): New test.
4701 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4703 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4704 newline if neither \c nor -n work, as that would output two
4705 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4707 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4709 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4710 This causes that any required macros inside will get before the if.
4711 * doc/autoconf.texi (autom4te.cache): A typo.
4713 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
4715 Undo previous change, except keep the change to
4716 lib/autoconf/programs.m4 that replaced grep with shell
4717 pattern-matching. This is because net-snmp configure reads stdin.
4718 Reported by Noah Misch.
4720 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
4722 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
4723 from /dev/null, as "configure" shouldn't read stdin, and this
4724 insulates us from problems (e.g., when testing for "cl").
4725 Suggested by Alexandre Duret-Lutz. Also, do this redirection
4726 before invoking "hostname" or "uname".
4727 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4728 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
4729 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
4730 "</dev/null" since it's now done at the top of 'configure'.
4731 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4732 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4733 Also, replace grep with shell pattern-matching, to save a process.
4735 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
4737 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4738 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
4739 avoid thinking that Allegro Common Lisp's "cl" command is a C++
4740 compiler.
4742 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
4744 * doc/autoconf.texi (Limitations of Usual Tools): Document that
4745 grep -q isn't portable. Improve grep -s explanation.
4746 Problem reported by Dan Manthey.
4748 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
4750 * doc/autoconf.texi (Special Shell Variables): Clarify
4751 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
4753 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4755 * doc/autoconf.texi: Use @acronym for DJGPP.
4756 Fix some @code's that should have been @env's, and vice versa.
4757 Sort environment variable names.
4758 Mention that shells no longer inherit IFS.
4759 Don't recommend PATH_SEPARATOR=';' so strongly.
4760 Mention that $RANDOM might expand to the empty string.
4761 "symlink" and "soft link" -> "symbolic link".
4762 Improve mktemp description (reported by Bruno Haible).
4764 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
4766 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
4767 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
4768 Likewise.
4769 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
4770 Likewise.
4772 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
4774 * NEWS: Mention AT_COPYRIGHT.
4776 * tests/local.at (AT_CMP): Use diff directly on input files rather
4777 than copying them.
4779 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
4780 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
4782 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4783 and Paul Eggert <eggert@cs.ucla.edu>
4785 * tests/autotest.at (Empty test suite): New test.
4786 * tests/torture.at (Substitute and define special characters)
4787 (Substitute a 2000-byte string, Define to a 2000-byte string)
4788 (Substitute a newline, Define a newline): New tests.
4790 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4792 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
4793 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
4794 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
4795 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
4796 (Standard regular expressions): New test.
4797 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
4798 excess test name quoting.
4799 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
4800 CPPFLAGS to `configure' instead of setting it in `configure'.
4802 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
4803 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
4804 on some platforms.
4806 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
4807 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
4809 * tests/local.at (AT_CMP): New macro.
4810 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
4811 (AC_SAVE_STATE): Move environment grep...
4812 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
4813 (AT_CONFIG_CMP): New macro.
4814 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
4815 * tests/c.at (Extensions): Do not exit early.

4818 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
4819 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
4821 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
4822 (AC_COPYRIGHT): Factor header comment portion out and move into...
4823 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
4824 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
4825 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
4826 --version output.

4833 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
4835 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
4837 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
4838 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
4840 Try not to generated lines of unlimited length, as POSIX places a
4841 2047-byte limit on line length of portable text files.
4842 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
4843 Use newline as a separator, not space.
4844 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
4845 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
4846 space.
4848 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4850 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
4851 as_func_*. Add test to check whether positional parameters
4852 are restored after function return.
4854 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
4856 * doc/autoconf.texi (Special Shell Variables): Mention _,
4857 BIN_SH, DUALCASE. Say that variables other than "status" are safe
4858 if they contain a lower-case letter. The DUALCASE problem was
4859 reported by Ralf Wildenhues.
4861 * bin/autoconf.as: Don't exit with status 0 after write failure
4862 with --help or --version.
4863 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
4864 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.

4868 * doc/autoconf.texi (Limitations of Usual Tools):
4869 Unicos 9 sed limitations.
4870 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
4871 to get the option-enhanced interface on older Crays. Try ftn for
4872 Fortran 95 (newer Crays).
4874 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
4876 * man/Makefile.am (.x.1): Go back to the simple solution, but take
4877 care to echo the commands, so the user knows what's going on.
4878 Modified from a suggestion by Stepan Kasal.
4880 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
4881 with a cross reference. Derived from a suggestion by Bruce Korb.
4883 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
4885 * doc/autoconf.texi (config.status Invocation): Warn about
4886 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
4887 * doc/install.texi (Defining Variables): Likewise.
4888 Based on a proposed patch by Ralf Wildenhues.
4890 * man/Makefile.am (.x.1): Make sure the required generated files
4891 are up to date. Problem and original solution proposed by Stepan Kasal.
4892 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
4893 implicit-man-prerequisites): New rules, used by the above.

4899 2005-01-29 Stepan Kasal <kasal@ucw.cz>
4901 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
4902 Update the long comment explaining it.
4904 m4_require no longer writes an ``is required by'' line to the
4905 execution stack. It contains only one bit of non-redundant
4906 information: that the macro was required, not called. And even
4907 this bit is useless in most situations: have you ever met a macro
4908 which both calls and requires the same macro?
4910 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
4911 (_m4_defun_pro_outer): ... only via this macro, for the outermost
4912 macro.
4913 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
4914 (m4_expansion_stack_pop): Remove the misplaced comment.
4915 (m4_require): Don't put the ``is required by'' line to the
4916 execution stack; slightly improve the out-of-a-defun error message.
4917 (_m4_divert_grow): New macro, counter for the temporary diversions.
4918 (_m4_require_call): Use it.
4919 * tests/m4sugar.at (m4_require): Expect output without the
4920 ``is required by'' messages.
4922 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4924 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
4925 rather than x for expr.
4927 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
4928 this is safe.
4929 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
4930 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

4932 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Likewise.
4933 * tests/mktests.sh: Likewise.
4935 2005-01-27 Akim Demaille <akim@epita.fr>
4937 Have autoheader honor --force.
4939 * doc/make-stds.texi, doc/standards.texi: Update from masters.
4940 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
4941 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
4942 from masters, so that FileUtils.pm's update_file provide --force
4943 support.
4944 * bin/autoheader.in: Pass $force to update_file so that
4945 config.h.in is always recreated when --force.
4947 2005-01-24 Stepan Kasal <kasal@ucw.cz>
4949 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
4951 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
4953 * doc/autoconf.texi (Limitations of Builtins): Clarify that
4954 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
4956 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
4958 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
4959 Warn about newline stripping in `` and $(). Update Solaris
4960 version to 9.
4961 (Limitations of Builtins): Use expr "X...", not expr "x...", as
4962 X insulates us from future changes to Posix.
4963 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline

5330 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5331 "char c = '\200';" rather than "char c = 0x80;" as the

5434 * doc/autoconf.texi (auindex): New macro.
5435 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
5436 Problem reported by Stepan Kasal.
5438 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>

5441 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
5442 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
5443 in test makefile.
5444 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
5445 readable; it's not true in OS/2-emx.
5447 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
5449 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
5450 "/usr/include", clear ac_x_includes instead of leaving it as "no"
5451 (trivial change). Problem and patch reported by Andrew Church in:
5452 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
5454 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
5456 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
5457 three args in examples. Problem reported by Frederik Fouvry in:

5459 Also, fix some minor spacing and punctuation bugs.
5461 2004-09-02 Akim Demaille <akim@epita.fr>
5463 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
5464 "case" to restore ordering.
5465 Reported by Stepan Kasal.

5481 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
5482 texinfo.tex for now (done by hand now).
5483 * Makefile.maint (wget_files, cvs_files):
5484 Remove ansi2knr.c; nobody uses it.
5485 (ansi2knr.c-url_prefix): Remove.
5486 (cvs-update): Fix test for failure. I don't know why it ever
5487 worked...
5489 * doc/autoconf.texi: Update URLs, some of which went stale.
5490 Use @uref rather than @href.
5492 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
5493 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
5495 * config/config.guess, config/config.sub, config/elisp-comp,
5496 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
5497 doc/fdl.texi, doc/standards.texi: Sync with master copy.
5499 * NEWS, TODO, configure.ac, bin/autoscan.in,
5500 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
5501 doc/install.texi, lib/Autom4te/Configure_ac.pm,

5505 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
5506 tests/tools.at, tests/torture.at:
5507 Use "file name" rather than "filename" or "path",
5508 to be consistent with the terminology of the GNU coding standards.
5510 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
5512 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
5513 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
5514 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
5515 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
5517 More fixes to support spaces in the name of the build directory.
5518 This isn't a complete fix but it's an improvement.
5520 * bin/autoconf.as (autom4te_options): New var.
5521 Use it instead of appending to AUTOM4TE, so that we can allow
5522 spaces in the build directory's absolute name.
5523 * bin/autoheader.in ($autoconf): Allow spaces in file names.
5524 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
5525 AT_CHECK_NOESCAPE): Likewise.
5526 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
5527 main program): Likewise.
5529 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
5531 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
5532 From Ralf Corsepius in:

5535 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
5537 * doc/autoconf.texi (Function Portability): Document isinf and
5538 and isnan. From a suggestion by Kevin Ryde.
5540 * lib/Autom4te/General.pm (END): Return correct exit status even
5541 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5543 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5545 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5546 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5547 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5549 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5551 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5552 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5553 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5554 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5555 * lib/autom4te.in (Automake-preselections): Preselect
5556 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5558 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5560 * lib/autom4te.in (Automake-preselections): Preselect
5561 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5562 trace them.
5564 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
5566 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
5567 Tru64.
5568 * doc/autoconf.texi (Shellology): Mention BIN_SH.
5569 Document problem with "`""`" in pdksh POSIX mode.
5571 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5573 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5574 with pdksh, too. Problem reported by Patrick Welche via
5575 Gary V. Vaughan.
5576 * doc/autoconf.texi (Shellology): Note that set -o posix is
5577 useful for pkdsh, too.
5579 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5581 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5582 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5583 Don't fail if ENV or BASH_ENV is readonly.
5584 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5585 etc. are read only. Problem reported by Ludovic Courtes.
5587 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5589 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5590 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5591 (trivial change)
5593 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5595 * doc/autoconf.texi (File System Conventions): Warn about
5596 names like "aux". Problem reported by Eric Blake.
5598 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5599 by zero instead of array size, so that we can use any arithmetic
5600 constant expression (instead of requiring an integer constant
5601 expression). This allows us to test expressions like DBL_MAX <
5602 LDBL_MAX, which didn't conform to the C standard using the old
5603 method.
5604 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5605 now that we can do floating-point tests at compile time.
5607 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5609 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5610 and LDBL_EPSILON, as the resulting expression isn't an
5611 integer constant expression and violates the C standard.
5612 Problem reported by Nelson H. F. Beebe. Also, check
5613 for "L" suffix, and check that long double doesn't have
5614 worse range or precision than double, that mixed-mode
5615 arithmetic doesn't generate a diagnostic, that double
5616 constants fit in long double.
5618 2004-06-03 Kevin Ryde <user42@zip.com.au>
5620 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5621 malloc(0) and realloc(NULL,size).
5623 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5624 Bob Proulx.
5626 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5628 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5629 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5630 by Jim Meyering.
5632 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5634 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5635 can be rewritten using if-then-else. Suggested by Bruno Haible.
5637 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5639 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5640 Problem reported by Stepan Kasal.
5642 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5644 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5645 change). Patch reported by Ralf Wildenhues in
5646 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5648 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5649 function F exists if the compiler and linker let you compile an
5650 expression like (F != 0). Recent versions of GCC optimize away
5651 the reference to F in that case, since every function address must
5652 be nonzero, so the link succeeds even if F does not exist.
5653 Problem reported by Manu in
5654 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5656 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5657 "Unix". Many uses changed.
5658 (Limitations of Builtins): Explain better why the ! command isn't
5659 portable.
5661 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
5663 * lib/autom4te.in (Automake-preselections): Preselect
5664 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5666 2004-05-19 Kevin Ryde <user42@zip.com.au>
5668 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5669 referencing AC_FUNC_STRERROR_R.
5671 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5672 note pessimistic assumption when cross compiling.
5674 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5676 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5677 (until 2004) invoked subcommands with sh -e, contra POSIX.
5678 Reported by Kevin Ryde.
5680 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5682 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5683 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5684 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5685 `test -f " /usr/bin/grep"', which _always_ failed.
5686 (AC_PROG_SED): Ditto bogus PATH fix.
5687 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5688 requires that grep correctly supports _multiple_ `-e' options, rather
5689 than stating only that grep should accept `-e'.
5691 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5693 Port to C99, which requires that 'exit' be declared.
5695 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5696 to ensure that stdlib.h is included.
5697 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5698 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5699 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5700 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5701 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5702 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5703 when using 'exit' in a test; C99 requires that 'exit' be declared.
5705 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5707 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5708 now prefers 'grep' implementations that accept -e.
5709 (Limitations of Usual Tools): Describe problems of traditional
5710 egrep and fgrep with long input lines, and of traditional grep
5711 with -e.
5712 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
5713 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
5714 All callers changed. Append /usr/xpg4/bin to the PATH, for
5715 Solaris.
5716 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
5717 the user with complaints about multiple -e options.
5718 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
5719 Define it with AC_PROG_GREP.
5720 * configure.ac (AC_PROG_GREP): Add.
5721 * lib/freeze.mk (GREP): New macro.
5723 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
5725 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
5726 a possible candidate only after all others fail, rather than
5727 consulting it first. This improves backward compatibility by
5728 better reflecting the way shell selection occurred in previous
5729 versions of Autoconf, and should help to avoid triggering latent
5730 problems in other packages, such as the one in Automake where zsh
5731 is not handled robustly:
5732 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
5733 Although it is not Autoconf's responsibility to work around
5734 problems in Automake, it nevertheless makes sense to avoid
5735 introducing unnecessary incompatibilites.
5737 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
5738 Gary V. Vaughan <gary@gnu.org>
5740 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
5741 how deeply nested we are when a suitable tool is found, set the
5742 ac_path_TOOL_found flag.
5743 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
5744 nested we are in this macro. Break out of all 3 nested loops if
5745 ac_path_TOOL_found is set.
5747 2004-04-21 Gary V. Vaughan <gary@gnu.org>
5749 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
5750 of the _AS_PATH_WALK loop too if GNU flavor is found.
5752 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
5754 * doc/autoconf.texi (Limitations of Make): Update documentation
5755 for `$<'. New entry `Long lines', based on a report from Simon
5756 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
5757 paragraph about DJGPP, based on a mail from Richard Dawe.
5759 2004-04-20 Paul Eggert <eggert@twinsun.com>
5761 * tests/c.at (C keywords): Don't assume that GCC supports
5762 "restrict" and "inline", as sufficiently-old GCC versions do not
5763 (also, GCC configured to be in pedantic C89 mode does not).
5764 Problem reported by Sumit Pandya in:
5765 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
5767 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
5768 consider -g to work if it generates warnings when plain compiles
5769 don't. Problem reported by Braden McDaniel in:
5770 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
5772 * doc/autoconf.texi (Slashes): New section, to document a problem
5773 reported by Jim Meyering in:
5774 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
5776 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
5777 linker output files before linking, to work around IRIX 6 linker bug.
5778 Problem reported by Rainer Orth in:
5779 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
5781 2004-04-20 Gary V. Vaughan <gary@gnu.org>
5783 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
5784 best tool so far counter rely on the tool path variable name to
5785 avoid checks for one tool being affected by the results of running
5786 the length check on a previous tool.
5788 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
5789 match expression argument, as different greps have different
5790 regular expression flavours.
5791 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
5792 literals.
5793 (AC_PROG_EGREP): Pass 'EGREP$'.
5794 (AC_PROG_GREP): Pass 'GREP$'.
5796 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
5798 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
5799 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
5801 2004-03-29 Paul Eggert <eggert@twinsun.com>
5803 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
5804 Types, Specific Compiler Characteristics, System Services,
5805 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
5806 etc. consistently instead of 'long', 'short', 'unsigned' etc.
5807 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
5808 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
5809 Likewise.
5810 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
5811 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
5812 AC_TYPE_OFF_T): Likewise.
5813 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
5814 Likewise.
5816 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
5817 pacify libtool 1.5.2. Fix quoting problems in sed command.
5819 2004-03-28 Paul Eggert <eggert@twinsun.com>
5821 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
5822 now defines HAVE_DECL_TZNAME if it is declared, when
5823 HAVE_STRUCT_TM_TM_ZONE is not defined.
5824 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
5825 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
5826 for HAVE_TZNAME.
5828 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
5830 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
5831 superfluous backslashing of quotes (") in sed expressions;
5832 thanks to Paul Eggert.
5834 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
5836 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
5837 Fortran compiler is ifort, also added pghpf; thanks to Nelson
5838 H. F. Beebe for the bug report.
5840 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
5842 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
5843 quoted -cmdline argument in Portland Group compiler (bug
5844 reported by Jeffrey J. Barteet).
5846 2004-03-25 Kevin Ryde <user42@zip.com.au>
5848 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
5849 (Run Time): ... here, where it's now mentioned.
5851 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
5853 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
5854 inherits from language Autoconf-without-aclocal-m4.
5855 (Customizing autom4te): Adjust example; the cache must now be
5856 disabled for language Autoconf-without-aclocal-m4.
5858 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
5859 Nathanael Nerode <neroden@twcny.rr.com>
5861 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
5862 AC_CHECK_TOOLS): Warn if a cross-tool is found without
5863 a prefix.
5864 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
5865 AC_CHECK_TARGET_TOOLS): New macros.
5866 * doc/autoconf.texi (Generic Programs): Document
5867 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
5868 AC_CHECK_TARGET_TOOLS, and warn for future changes
5869 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
5870 AC_CHECK_TOOLS.
5871 (Specifying Names): Document the reason for these future
5872 behavioral changes.
5873 * tests/mktests.sh: Do not generate tests for the
5874 new macros.
5875 * NEWS: Document these changes.
5877 * doc/autoconf.texi: Avoid macros with unbraced arguments,
5878 they make TeX hang up.
5880 2004-03-15 Paul Eggert <eggert@bogus.example.com>
5882 * NEWS: New macro AC_CHECK_ALIGNOF.
5883 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
5884 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
5885 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
5886 vowel.
5887 (AC_CHECK_ALIGNOF): New macro.
5888 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
5889 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
5890 those for sizeof.
5892 2004-03-03 Paul Eggert <eggert@twinsun.com>
5894 * bin/Makefile.am (edit): Don't use $< in a context where
5895 POSIX doesn't require support for it. Use $@.in instead.
5896 Problem reported by Anthony N. Frasso in
5897 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
5898 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
5900 2004-02-23 Gary V. Vaughan <gary@gnu.org>
5902 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
5903 from the next generation of Libtool.
5904 * lib/autom4te.in (Autoreconf-preselections): Ditto.
5906 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5908 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
5909 is not always thread-safe. Report from Nathanael Nerode.
5911 2004-02-18 Paul Eggert <eggert@twinsun.com>
5913 Fix a dependencies problem, stemming from a Autoconf 2.59 build
5914 problem on QNX reported by Stephen Rasku in
5915 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
5917 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
5918 $(m4sh_m4f_dependencies); this removes a FIXME.
5919 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
5920 (MAINTAINERCLEANFILES): Split into pieces,
5921 one per related section. Add $(srcdir)/wrapper.in.
5923 2004-02-09 Paul Eggert <eggert@twinsun.com>
5925 * doc/autoconf.texi (Setting Output Variables): Emphasize that
5926 AC_SUBST provides no portable way to escape literal newlines.
5928 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
5929 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
5930 Darwin uses -lcrt2.o and there's little point to cataloging all
5931 the system variants. Partial fix reported by Andreas Waechter in:
5932 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
5933 for bug reported by Nelson H. F. Beebe in:
5934 http://mail.gnu.org/archive/html/bug-autoconf/2003-12/msg00090.html
5936 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
5938 * doc/autoconf.texi (AU_DEFUN): Fix English,
5939 suggested by Paul Eggert.
5940 * lib/autoconf/autoupdate.m4: Correct reference to
5941 acobsolete.m4, suggested by Alexandre Duret-Lutz.
5943 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
5945 * bin/autoupdate.in: Define __file__ so that warnings
5946 refer to the correct file.
5947 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
5948 the behavior of the third argument.
5949 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
5950 correctly the behavior of the third argument. Document
5951 what the three macros that AU_DEFUN defines do. Fix
5952 warning message when the third argument includes $0
5953 (reported by Alexandre Duret-Lutz).
5955 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5956 Eric Sunshine <sunshine@sunshineco.com>
5957 Paul Eggert <eggert@twinsun.com>
5959 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
5960 (AS_INIT): Output shell initialization there. Removed optional
5961 parameter. Expand _AS_SHELL_FN_SPY.
5962 (AS_INIT_WITH_SHELL_FN): Removed.
5963 (_AS_SHELL_FN_SPY): New macro.
5964 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
5965 macros.
5966 (AS_SHELL_SANITIZE): Remove loop to find better shell
5967 and documentation for the parameter.
5968 (_AS_DETECT_BETTER_SHELL): Move it here.
5969 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
5970 (_AS_RUN): Move it here, support testing with eval.
5971 (AS_REQUIRE_SHELL_FN): Require shell functions when
5972 it is used.
5973 (_AS_LINENO_WORKS): Put around braces, we do not
5974 trigger the bash bug anymore.
5975 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
5976 use AS_INIT_WITH_SHELL_FN.
5977 * bin/autoconf.in, tests/wrapper.in: Regenerated.
5979 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5981 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
5982 * doc/autoconf.texi: Don't say that the third parameter
5983 is broken.
5984 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
5985 (AU_DEFUN): Honor the third parameter, create autoupdate
5986 macros with AU_DEFINE.
5987 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
5988 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
5989 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
5990 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
5991 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,
5992 AC_ARG_ARRAY, AC_CYGWIN, AC_EMXOS2, AC_MINGW32,
5993 AC_XENIX_DIR): Likewise.
5994 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS,
5995 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
5996 * lib/autoconf/status.m4: Remove FIXME.
5997 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
5998 that the macro is not present anymore in the updated
5999 configure.ac.
6000 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
6001 of autoupdate.
6003 2004-01-28 Paul Eggert <eggert@twinsun.com>
6005 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
6006 copyright years.
6007 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
6008 2003 (except 1997) to the list of copyright years. This undoes
6009 the 2003-05-22 change, which removed the older years from the list.
6010 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
6012 2004-01-27 Gary V. Vaughan <gary@gnu.org>
6013 Albert Chin-A-Young <china@thewrittenword.com>
6015 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
6016 grep or ggrep program in PATH that accepts as long lines as
6017 possible.
6018 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
6019 AC_PROG_GREP.
6020 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
6021 egrep and fgrep respectively if $GREP -E/-F don't work.
6022 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
6023 _AC_PROG_GREP, and AC_PROG_SED.
6024 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
6025 longest input length accepted by a command.
6026 (AC_PROG_SED): Use it.
6027 * doc/autoconf.texi (Particular Programs): Document the changes.
6028 * NEWS: Updated.
6030 2004-01-27 Paul Eggert <eggert@twinsun.com>
6032 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
6033 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
6034 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
6035 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
6037 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
6038 bin/autoconf.in, config/Makefile.in, config/config.guess,
6039 config/config.sub, config/install-sh, config/mdate-sh,
6040 config/mkinstalldirs, config/texinfo.tex, doc/Makefile.in,
6041 lib/Makefile.in, lib/Autom4te/Makefile.in,

6050 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
6051 tests/actypes.at: Regenerate and/or sync with original
6052 sources.
6054 2004-01-26 Paul Eggert <eggert@twinsun.com>
6056 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6057 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6058 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6059 not <inttypes.h>. Problem reported by Tim Mooney in
6060 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6061 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6062 Likewise.
6064 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6065 otherwise "make check" fails because it forbids cmp (I guess
6066 because cmp treats files as binary on DOS-like systems).
6068 * tests/mktests.sh: Update copyright date to 2004, since some tests
6069 have changed in 2004.
6071 2004-01-23 Gary V. Vaughan <gary@gnu.org>
6073 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
6074 non-truncating sed or gsed program in PATH.
6075 * tests/acprograms.at: Add it.
6076 * doc/autoconf.texi (Particular Programs): Document it.
6077 * NEWS: Updated.
6079 2004-01-15 Paul Eggert <eggert@twinsun.com>
6081 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6082 -std1 disables some useful extensions on Tru64. Problem reported
6083 by N. Lichtmaier in
6084 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6086 2004-01-14 Paul Eggert <eggert@twinsun.com>
6088 * doc/autoconf.texi (Programming in M4sh): Document that
6089 AS_MKDIR_P succeeds if the destination is a symbolic link
6090 to an existing directory.
6091 (Limitations of Usual Tools): Note that mkdir -p might not
6092 succeed on symlinks to directories.
6094 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6096 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6097 * bin/autoheader.in: Grammar fix in message.
6098 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
6099 Test for dir before calling mkdir -p. (trivial changes)
6101 2004-01-13 Eric Blake <ebb9@byu.net>
6103 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
6104 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6106 2004-01-10 Jim Meyering <jim@meyering.net>
6108 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6110 2004-01-09 Paul Eggert <eggert@twinsun.com>
6112 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6113 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6114 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6115 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6116 AC_COMPILE_IFELSE, since we now assume our caller invokes
6117 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6118 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6119 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6120 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6122 2004-01-07 Paul Eggert <eggert@twinsun.com>
6124 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6125 `"'...'"`, as it's confusing (and I suspect it may not work on
6126 some platforms). The code was incorrect anyway, as it assumed
6127 that \$ evaluated to itself in that context. Reported by
6128 Alexandre Duret-Lutz.
6130 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6132 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
6133 and _LT_AC_TAGCONFIG.
6135 2004-01-06 Paul Eggert <eggert@twinsun.com>
6137 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6138 example, and add more examples. Reported by Eric Sunshine.
6140 2004-01-05 Paul Eggert <eggert@twinsun.com>
6142 * doc/autoconf.texi (Limitations of Usual Tools):
6143 Remove warning against "rm -fr" introduced yesterday; it
6144 was a false alarm.
6146 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6147 autoscan, autoupdate, ifnames): Don't use chmod -w.
6148 * lib/Makefile.am (autom4te.cfg): Likewise.
6149 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6150 "chmod -w".
6152 2004-01-04 Paul Eggert <eggert@twinsun.com>
6153 Paolo Bonzini <bonzini@gnu.org>
6155 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
6156 by doing lineno substitution only on lines containing "$LINENO".
6158 2004-01-04 Paul Eggert <eggert@twinsun.com>
6160 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6161 Use "rm -f" to remove conftest.sed, not plain "rm".
6162 Bug reported by David Relson in
6163 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6165 * Makefile.am (autom4te-update):
6166 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6167 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6168 * doc/autoconf.texi (Guidelines): Likewise.
6169 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

6173 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
6174 * tests/Makefile.am (clean-local): Likewise.
6175 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
6176 srcdir): Likewise.
6177 * doc/autoconf.texi (Limitations of Usual Tools):
6178 Warn against "rm -fr".
6180 2004-01-03 Paul Eggert <eggert@twinsun.com>
6182 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6183 -c -o might not work. From a suggestion by Kevin Ryde.
6184 (C Compiler, Generating Sources, Limitations
6185 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6186 Don't put '-o' after non-options, as POSIX doesn't allow this.
6187 Mention that cc's name might be gcc or c89 or whatever.
6189 2004-01-04 Kevin Ryde <user42@zip.com.au>
6191 * doc/autoconf.texi: Add various further index entries.
6193 2003-12-29 Paul Eggert <eggert@twinsun.com>
6195 * bin/autoreconf.in (autoreconf_current_directory):
6196 Fix typo: mkdir without umask arg.
6198 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6200 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6201 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6202 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6203 explanation clearer.
6205 2003-12-24 Andreas Schwab <schwab@suse.de>
6207 * doc/autoconf.texi (Default Includes): Fix misspelling of
6208 AC_INCLUDES_DEFAULT.
6210 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
6212 * configure.ac: Test if sh -n works.
6213 * configure: Regenerate.
6214 * tests/atlocal.in: Store the result here.
6215 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
6216 tools.at, looking in atlocal's ac_cv_sh_n_works instead
6217 of explicitly testing.
6218 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
6219 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
6220 * tests/tools.at (Syntax of the shell scripts): Simplify
6221 using AT_CHECK_SHELL_SYNTAX.
6222 (Syntax of the Perl scripts): Remove definition of
6223 AT_CHECK_PERL_SYNTAX.
6225 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
6227 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
6228 stderr to /dev/null.
6229 * bin/autoconf.in: Regenerate.
6230 * bin/wrapper.in: Regenerate.
6232 2003-11-26 Paolo Bonzini <bonzini@gnu.org>
6234 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
6235 Extracted from AS_SHELL_SANITIZE.
6236 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
6237 macros.
6238 (AS_SHELL_SANITIZE): Move reinvocation code from
6239 _AS_LINENO_WORKS, use it to find out if shell
6240 functions work.
6241 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
6242 does not work.
6243 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
6244 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN
6245 was called.

6255 (&sizes): New.
6256 Use them.

6258 them on the fly.
6260 2003-11-24 Akim Demaille <akim@epita.fr>
6262 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

6290 parameter of AU_DEFUN.
6291 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.
6292 (AU_DEFUN): Remove the third parameter, it was not used.
6293 Use AC_DEFUN directly, not AU_DEFINE.
6294 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
6295 the expanded body, consistently with other macros such as AC_USG.
6297 2003-11-17 Paul Eggert <eggert@twinsun.com>
6299 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
6300 into the initial confdefs.h, to work around a bug in NextStep 3.3
6301 patch 3 reported by Eric Sunshine.
6303 2003-11-15 Kevin Ryde <user42@zip.com.au>
6305 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
6306 than $target since the latter is not usual, add guidelines on when to
6307 use or not use the system type.
6309 2003-11-12 Derek Price <derek@ximbiot.com>
6311 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
6312 typo misrepaired by an auto-spellcheck.
6314 2003-11-12 Akim Demaille <akim@epita.fr>

6464 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
6466 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
6467 cross test.
6469 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
6471 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
6472 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

6483 Issue a more-informative diagnostic.
6484 Problems reported by Eric Sunshine.
6486 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
6488 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
6489 -mGLOB_options_string stuff for Intel ifc, which can cause

6499 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
6500 that future autopoint/aclocal/automake/autoreconf will be able

6509 -lcrt[01].o.
6511 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
6513 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6514 cache variable instead of $G77 to decide whether to include -O2,
6515 since $G77 is specific to Fortran 77.
6517 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6519 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
6520 free" flag. Re-order flags tested into rough order of popularity.
6522 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6524 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
6525 arguments so that it can be used with syntax identical to
6526 AC_PROG_F77, and so that we can more easily decide to
6527 remove/deprecate the DIALECT optional argument in the future if it
6528 proves troublesome.
6529 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
6530 non-freeform-supporting compilers. Document freeform flags.
6532 2003-10-03 Akim Demaille <akim@epita.fr>
6534 * configure.ac: Look for emacs, not macs.

6544 2003-10-03 Akim Demaille <akim@epita.fr>
6546 * configure.ac: Quotation and formatting changes.

6568 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
6569 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
6571 2003-09-30 Akim Demaille <akim@epita.fr>
6573 * config/announce-gen (&print_news_deltas): Extracted from...
6574 (&print_changelog_deltas): here.

6593 Problem reported by Lars J. Aas in
6594 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
6595 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
6596 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
6597 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
6599 2003-09-26 Akim Demaille <akim@epita.fr>
6601 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6602 directory for AC_CONFIG_COMMANDS' first argument exists.
6603 This makes valid the invocation of _AC_SRCPATH that follows.
6604 Reported by Eric Sunshine.
6605 * doc/autoconf.texi (Configuration Commands): Adjust.
6607 2003-09-26 Akim Demaille <akim@epita.fr>
6609 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6610 Reported by Ralf Corsepius.
6612 2003-09-26 Akim Demaille <akim@epita.fr>
6614 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6615 arguments.
6616 Actually, use AU_ALIAS.
6617 From Bruno Haible.
6619 2003-09-26 Paul Eggert <eggert@twinsun.com>
6621 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
6622 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.

6626 2003-09-26 Akim Demaille <akim@epita.fr>
6628 The test suite are sometimes assigning timings incorrectly.
6629 Reported by Henk Krus.
6630 Diagnosed by Nicolas Joly.
6632 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6633 AT_help_all.
6634 Instead of making AT_help a sequence of assignments to grow
6635 $at_help_all, just make AT_help_all be the growing contents of
6636 $at_help_all, and make a single assignment in...
6637 (AT_INIT): here.
6638 (at_times_skip): Flip the meaning and rename as...
6639 (at_times_p): this.
6640 (AT_INIT): When summarizing the test that ran, remove
6641 $at_times_file after use, and check it is present before trying to
6642 use it.
6644 2003-09-25 Akim Demaille <akim@epita.fr>
6646 Version 2.57d.
6648 * bin/Makefile.am (edit): Handle '@configure_input@'.
6649 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
6650 (ifnames): chmod -w.
6651 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6652 executables, not bin/ executables! Otherwise all the magic needed
6653 to find non installed files is turned off. This caused a failure
6654 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6655 as found in its environment (sent by tests/autoreconf): pointing
6656 to bin/autom4te that could not find its files.
6657 * tests/mktests.sh: Force the replacement of generated files, for
6658 the sake of "mv" program that are interactive when overwriting a
6659 -w file.
6660 * config/install-sh: Upgrade from CVS Automake.
6662 2003-09-23 Paul Eggert <eggert@twinsun.com>

6665 versus test -L issues.
6667 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
6668 Paul Eggert <eggert@twinsun.com>
6670 Trivial change to support GCC's configuration procedure.
6671 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
6672 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
6673 about inconsistency if the preprocessor is set to give errors for
6674 any warning.
6675 * doc/autoconf.texi (C Compiler Characteristics): Document this.
6677 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
6679 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
6680 and XFile.pm from Automake.

6693 2003-09-12 Akim Demaille <akim@epita.fr>
6695 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
6696 not asm/types.h.
6698 2003-09-11 Akim Demaille <akim@epita.fr>
6700 * doc/autoconf.texi (Header Portability): linux/random.h.
6701 From Peter Hendrickson.
6703 2003-09-10 Akim Demaille <akim@epita.fr>
6705 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
6706 willing to edit the output files.
6708 2003-09-10 Akim Demaille <akim@epita.fr>
6710 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
6711 and AC_FC_FREEFORM.
6712 * tests/mktests.sh: Skip AC_FC_SRCEXT.
6713 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
6715 2003-09-09 Akim Demaille <akim@epita.fr>

6728 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
6729 Improve the accuracy of the wording about obsolescence.
6730 From a suggestion by Ian Lance Taylor in
6731 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
6733 2003-09-05 Paul Eggert <eggert@twinsun.com>
6735 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
6736 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
6738 2003-09-04 Akim Demaille <akim@epita.fr>
6740 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
6741 AC_FUNC_WAIT3.
6743 2003-09-04 Akim Demaille <akim@epita.fr>
6745 * bin/autom4te.in: Use &fatal where more appropriate than &error.
6746 (freeze): When exiting, use $exit_code.

6749 2003-09-04 Akim Demaille <akim@epita.fr>
6751 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
6753 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
6755 Add support for newer Fortran dialects. The F77 interface is
6756 unchanged, and continues to support Fortran 77. New FC macros
6757 correspond to all the old F77 macros, with output variables FC,
6758 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
6759 available dialect, but older dialects can be specified. There are
6760 new macros AC_FC_SRCEXT to set the source extension, and
6761 AC_FC_FREEFORM to accept free-form source files.
6763 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
6764 New macros.
6765 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

6781 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
6782 Rewrite in terms of the above.
6783 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
6784 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

6790 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
6791 Document problems with timestamp resolution that 'make', 'cp -p', and
6792 'touch -r' have.

6796 * tests/m4sugar.at (cross_warning): Make sure to enable the
6797 output, so that we can track spurious m4sugar output.
6798 * tests/local.at: Require 2.57.
6799 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
6800 are defaulted by AT_CHECK anyway.
6801 Use AT_CHECK_AUTOM4TE.
6802 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
6803 missing dnl.
6805 2003-08-27 Akim Demaille <akim@epita.fr>
6807 * bin/autoheader.in: Issue the "Using auxiliary..." message only
6808 when -Wobsolete is set.
6809 Set it on by default.
6810 Suggested by Klee Dienes.
6812 2003-08-27 Akim Demaille <akim@epita.fr>
6814 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
6815 documentation.
6816 From Guido Draheim.
6818 2003-08-26 Akim Demaille <akim@epita.fr>
6820 * doc/autoconf.texi (Output): Make clear that one can run code
6821 after AC_OUTPUT.
6823 2003-08-25 Akim Demaille <akim@epita.fr>
6825 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
6826 CVS Bison.
6828 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
6830 * bin/autoreconf.in (parse_args): Do not pass --no-force to
6831 Automake versions prior to 1.8.

6842 2003-08-22 Akim Demaille <akim@epita.fr>
6844 Version 2.57b.
6846 * Makefile.cfg (local-checks-to-skip): New.
6847 * Makefile.maint (local-check): Rename as...
6848 (local-checks-available): this.
6849 (local-check): New.
6851 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
6852 * configure.ac: Require Automake 1.7.6.
6854 2003-08-22 Akim Demaille <akim@epita.fr>
6856 Output stack traces in warnings.
6858 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
6859 Replace the former...
6860 (m4_warn): Pass the call stack to _m4_warn.
6861 * bin/autom4te.in: Adjust to output the call stack.
6862 * tests/m4sugar.at (m4@&t@_warn): Adjust.
6864 2003-08-22 Akim Demaille <akim@epita.fr>
6866 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
6867 * bin/autom4te.in: Adjust.
6869 2003-08-21 Akim Demaille <akim@epita.fr>
6871 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
6872 (&verbose): Remove.
6873 (&getopt): Adjust the note and verb channels, depending upon
6874 --verbose.
6875 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
6876 * bin/autoupdate.in: Adjust.
6877 Use &verb, not &verbose.
6879 2003-08-21 Akim Demaille <akim@epita.fr>
6881 * bin/autoheader.in (&parse_args): Use &parse_warnings and
6882 &parse_WARNINGS.
6883 ($help): Use Autom4te::ChannelDefs::usage.
6884 * bin/autoscan.in: Use Autom4te::ChannelDefs.
6885 * lib/Autom4te/General.pm: Don't export error: you don't own it.
6887 2003-08-21 Akim Demaille <akim@epita.fr>
6889 First stab at preserving warnings between calls to autom4te,
6890 including when the cache is used.
6892 There are still several issues: (i) there are too many runs of m4
6893 (one for include, one for warnings, and some more), (ii) warnings
6894 spreading on several lines are not handled gracefully, (iii) the
6895 code meant to have the call stack display for errors does not work
6896 (its handling should move from m4 to autom4te).
6898 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
6899 Use them.
6900 (@preselect): Add m4_warn.
6901 ($exit_status): Remove, use $exit_code.
6902 ($help): Use Autom4te::ChannelDefs::usage.
6903 (&handle_m4): No longer define the m4_warnings.
6904 At each run, extract and report the warnings.
6905 Always cache the result, including if the exit status is on
6906 failure, since if nothing changes, we should result in the same
6907 failure, hence we can use the cache.
6908 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
6909 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
6910 Remove.
6911 (m4_warn): Redefine as a do-nothing: it is its invocation that
6912 matters, as warnings are now reported via traces.
6913 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
6914 the contents of m4_warn: make it _call_ m4_warn, so that tracing
6915 the latter reveals calls to the former.
6917 Adjust the tests.
6919 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
6921 2003-08-21 Akim Demaille <akim@epita.fr>
6923 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
6924 Use them.
6926 2003-08-21 Akim Demaille <akim@epita.fr>
6928 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
6929 forward order.
6930 * lib/Autom4te/ChannelDefs.pm: Doc typos.
6931 (&parse_warnings): Accept a list of warning requests.
6932 (&usage): Return a string, not a side effect.
6933 (cross): New warning category.
6935 2003-08-21 Akim Demaille <akim@epita.fr>
6937 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
6938 (&require_configure_ac): Accept an optional directory argument.
6939 ($configure_ac): Remove.
6940 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
6941 (&catfile): Remove.
6942 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
6943 * bin/autoscan.in: Adjust.
6945 2003-08-20 Akim Demaille <akim@epita.fr>
6947 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
6948 Reported by Alexandre Duret-Lutz.
6950 2003-08-20 Akim Demaille <akim@epita.fr>
6952 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
6953 * bin/autom4te: Adjust.
6954 In particular, be Autoconf tools are really silent when properly
6955 working, bind the verbosity of the 'note' channel to $verbose.
6956 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
6957 (&xsystem, &contents): Remove, since they are exported by...
6958 * lib/Autom4te/FileUtils.pm: this.
6959 More perldoc.
6960 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
6961 * lib/Autom4te/FileUtils.pm: here.
6963 2003-08-20 Akim Demaille <akim@epita.fr>
6965 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
6966 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
6967 from CVS Automake.
6969 2003-08-20 Akim Demaille <akim@epita.fr>
6971 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
6972 (autom4te-update): New.
6973 * Makefile.cfg (update): Bind autom4te-update.
6975 2003-08-19 Derek Price <derek@ximbiot.com>
6977 * lib/autotest/general.m4: Comment various HELP_* diversions.
6978 (PARSE_ARGS_BEGIN): New section for option parsing related
6979 initialization.

6985 * config/announce-gen, Makefile.cfg: New.
6986 * Makefile.am: Adjust.
6987 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
6989 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
6991 * lib/autom4te.in (Automake-preselections): Preselect
6992 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
6993 and m4_sinclude.
6995 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
6997 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
6998 (Autoconf-without-aclocal-m4): ... this new language.
6999 * doc/autoconf.texi (autom4te Invocation): Mention
7000 Autoconf-without-aclocal-m4.

7004 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
7005 RUN-IF-PASS optional arguments.

7014 STDOUT & STDERR arguments.
7016 2003-08-14 Derek Price <derek@ximbiot.com>
7018 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
7019 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7020 shorter column three. Add DESCRIPTION to log file content.
7022 2003-08-13 Derek Price <derek@ximbiot.com>
7024 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
7025 output.
7027 2003-08-12 Derek Price <derek@ximbiot.com>
7029 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
7030 (AT_CHECK_NOESCAPE): Move core functionality to...
7031 (_AT_CHECK): ...this new macro.
7033 2003-08-07 Derek Price <derek@ximbiot.com>
7035 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
7036 (AT_CHECK_NOESCAPE): ...to this new macro.
7038 2003-07-31 Paul Eggert <eggert@twinsun.com>
7040 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
7041 in Bash 2.01. Problem reported by Brian Gough in
7042 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
7044 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
7046 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
7047 -lcrt1.o, for OS X. (trivial change)
7049 2003-07-07 Paul Eggert <eggert@twinsun.com>
7051 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
7052 inside '#ifndef __cplusplus'. Problem reported by
7053 Bob Friesenhahn.
7055 2003-07-06 Bill Clarke <llib@computer.org>
7057 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7058 'long', not 'int', for benefit of Sun's recent C++ compilers
7059 (trivial change). See:
7060 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
7061 (This really should be 'intptr_t', not 'long', but that would
7062 take more work.)
7064 2003-06-25 Akim Demaille <akim@epita.fr>
7066 * lib/Makefile.am (autom4te.cfg): Make it read only.
7067 Depend on Makefile since it contains substitutions.
7068 From Paolo Bonzini.
7069 * lib/autom4te.in (args): Add local.at? for Autotest args.
7070 This change was made on autom4te.cfg which is generated.
7071 Reported by Raja R. Harinath.
7073 2003-06-25 Akim Demaille <akim@epita.fr>
7075 * doc/autoconf.texi (Header Portability): sys/mount.h.
7076 From Gareth McCaughan.
7078 2003-06-23 Akim Demaille <akim@epita.fr>
7080 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7081 not all of them. This fixes 1. the fact that when testing
7082 Autoconf there are many many config.log, 2. the incorrect use of
7083 top_srcdir to find config.log.
7084 Don't mix the detailed output of failed test with the summary of
7085 failures. Rather, append detailed log afterwards.
7087 2003-06-23 Akim Demaille <akim@epita.fr>
7089 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7090 always run: output config.log on $at_group_log.
7092 2003-06-23 Akim Demaille <akim@epita.fr>
7094 * tests/torture.at (#define header templates): Don't use quotes in
7095 C++ comments as it puzzles Emacs' sh font-lock-mode.
7097 2003-06-23 Akim Demaille <akim@epita.fr>
7099 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
7100 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
7101 * tests/atspecific.m4: Rename as...

7104 * tests/local.at: here.
7105 * tests/Makefile.am: Adjust.
7106 * doc/autoconf.texi (testsuite Scripts): Adjust.
7108 2003-06-21 Kevin Ryde <user42@zip.com.au>
7110 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
7111 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
7112 ensuring we add -std1 for full-ANSI.
7114 * doc/autoconf.texi (hdrindex): New macro.
7115 Add index entries for portability of various standard header files.
7117 2003-06-20 Akim Demaille <akim@epita.fr>
7119 * configure.ac: Bump to 2.57b.
7121 2003-06-20 Akim Demaille <akim@epita.fr>
7123 Version 2.57a.
7125 2003-06-20 Akim Demaille <akim@epita.fr>
7127 * bin/autom4te.in: Don't rely on $HOME being defined.
7128 Reported by Marc Espie as PR/233.
7130 2003-06-20 Akim Demaille <akim@epita.fr>
7132 * lib/autotest/general.m4: Use at_times_file only if used.
7133 From Nicolas Joly.
7135 2003-06-20 Akim Demaille <akim@epita.fr>
7137 * config/config.guess, config/config.sub, config/elisp-comp,
7138 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
7139 Update from masters.
7141 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
7143 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
7144 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7145 (TEST_SCRIPT): New diversion.
7146 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7147 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7148 (AT_INIT): Support for expected failures.
7150 2003-06-02 Akim Demaille <akim@epita.fr>
7152 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7153 changes.
7154 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7155 Autoconf nor Automake.
7156 (&contents): New, from Automake.
7157 PODify.
7159 2003-05-28 Paul Eggert <eggert@twinsun.com>
7161 * NEWS, doc/autoconf.texi (Particular Functions),
7162 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7163 is the inverse of localtime.
7165 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7167 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7168 (handle_exec_errors): New function. Work around $! being
7169 altered by WEXITSTATUS.
7170 (xqx, xsystem): Use handle_exec_errors.
7172 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7174 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7175 Do not call `_exit()', simply modify `$?'.
7176 (xsystem): Reset $! before running system, and check it afterward.
7177 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7178 63 for version mismatches.
7180 2003-05-23 Akim Demaille <akim@epita.fr>
7182 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7183 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7184 the middle of a line).
7185 * lib/m4sugar/m4sugar.m4: Likewise.
7186 Remove useless spaces in comments.
7188 2003-05-23 Akim Demaille <akim@epita.fr>
7190 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7191 exit 63, so that we (or Automake's "missing") can tell the
7192 difference with a plain failure.
7193 * doc/autoconf.texi (Notices): Adjust.
7195 2003-05-23 Akim Demaille <akim@epita.fr>
7197 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7198 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7199 White spaces cleanup.
7201 2003-05-22 Jim Meyering <jim@meyering.net>
7202 Paul Eggert <eggert@twinsun.com>
7204 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7205 Remove `#include <stdlib.h>' from the list; we should never
7206 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7207 resulting namespace pollution would cause other tests to fail.
7208 Configure scripts run with some older versions of g++ and HP's
7209 aCC would fail due to such an #include. Problems reported by
7210 Matthew Mueller in <http://bugs.debian.org/120704> and by
7211 Keith Bostic in
7212 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7213 In the test, use the test declaration before including <stdlib.h>,
7214 as that's closer to how it'll be used.
7216 2003-05-23 Akim Demaille <akim@epita.fr>
7218 * doc/autoconf.texi (Header Portability): ucred.h.
7219 From Ian Redfern.
7221 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7223 Overhaul Autotest's logging: generate separate log files
7224 in testsuite.dir/NNN/testsuite.log, and append them to
7225 testsuite.log instead of re-running the test verbosely.
7227 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7228 file descriptor, write 0 to at_status_file instead of setting
7229 at_status=0, initialize some new variables (at_status_file,
7230 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7231 to rerun the tests, instead append the at_group_log to the
7232 at_suite_log when a test fails.
7233 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7234 with the AS_MESSAGE_LOG_FD redirected to stdout.
7235 (AT_CLEANUP): save the output status in $at_status_file
7236 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7237 its original place.
7238 (AT_CHECK): since tests are run with a redirected stdout,
7239 and used to be re-run in verbose mode, turn some $at_verbose
7240 into echo, and don't redirect the output of testing stdout
7241 and stderr.
7243 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7244 the name of the debugging directory and information about
7245 its contents.
7247 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7249 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
7250 parameter.

7362 and truncate.
7364 2003-05-06 Akim Demaille <akim@epita.fr>
7366 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7367 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7368 by aclocal.m4 is changed it might require the importing of another
7369 m4 extension file, i.e., aclocal must be run.
7371 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7372 (&parse_args): Use --force with aclocal if required and supported.

7380 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7381 argument instead of a file name, so that the request file remains
7382 open during the whole autom4te run.
7383 ($icache_file): New.
7384 (&freeze): Lock the $icache_file.
7386 2003-04-29 Derek Price <derek@ximbiot.com>
7388 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7389 seperator with m4_append_uniq(). It doesn't work.
7390 (AT_CLEANUP): Add `;' to end of at_help_all.

7394 to support the new --keywords behavior.
7396 2003-04-27 Karl Berry <karl@freefriends.org>
7398 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7399 align better with others. I also made some of the individual
7400 entries on one line, for brevity and to make it easier for me to
7401 sort my dir-example file in the Texinfo distribution :).

7468 header causes problems.
7470 2003-03-28 Akim Demaille <akim@epita.fr>
7472 * tests/torture.at (Configuring subdirectories): Require aclocal
7473 1.4, otherwise the test fails, as it does support configure.ac.

7478 * doc/autoconf.texi (C Compiler): `#line' portability.

7484 layout in order to allow scripting around test groups.
7486 2003-03-27 Derek Price <derek@ximbiot.com>
7488 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
7489 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and

7500 * tests/m4sh.at (AS_HELP_STRING): New test.
7502 * tests/acgeneral.at: Regenerated.
7504 2003-03-26 Derek Price <derek@ximbiot.com>

7507 sense. Verbosify the diversion definitions comment.

7511 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to

7545 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
7546 Tru64 make in the "target lookup" section.
7547 (Automake): Automake 1.5+ no longer requires special tools to be
7548 present on the developer's host.

7564 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
7565 to cope with DOS-style absolute paths, when constructing
7566 ${ac_make}.
7568 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
7569 When constructing paths with IFS=:, quote the path. If we're
7570 constructing a DOS-style absolute path, we don't want to split it
7571 on the colon.
7573 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
7574 in description.
7576 2003-02-25 Pavel Roskin <proski@gnu.org>

7588 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
7589 to fix a mismatch between example and discussion.
7591 2003-02-24 Kevin Ryde <user42@zip.com.au>
7593 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
7594 format starting with "-".
7596 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7598 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
7599 is not portable inside Makefile.
7601 2003-02-20 Akim Demaille <akim@epita.fr>
7603 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
7604 compiler says yeah, but preproc says nope, compiler is right.
7605 Conversely, prompt the reader to send a bug report to the
7606 maintainers of the package, not of Autoconf.
7608 2003-02-20 Klee Dienes <kdienes@apple.com>
7610 * bin/autoreconf.in (autoreconf_current_directory): Properly
7611 handle an empty aclocal.m4.

7615 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Quote
7616 $ac_prefix_program.
7617 From Larry Jones.
7619 2002-12-23 Paul Eggert <eggert@twinsun.com>
7621 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7622 innocuous variant befor including <limits.h> or <assert.h>. This
7623 works around a bug reported by Albert Chin: HP-UX 11i
7624 (and earlier versions) have a <limits.h> that declares
7625 gettimeofday and many other functions.
7627 2002-12-03 Paul Eggert <eggert@twinsun.com>
7629 Version 2.57.
7631 * NEWS, configure.ac: Update version.
7633 * doc/fdl.texi: Upgrade to FDL version 1.2.
7635 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7636 nontrivially in main's body, so that f's external declaration is
7637 not optimized away in AIX. This should fix the bug reported by
7638 Martin Frydl in
7639 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7641 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7642 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7643 defined, to support freestanding compilers. This should fix the
7644 bug reported by Momchil Velkov in
7645 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7647 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
7648 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
7649 obsolete AC_CHECK_TYPE. The missing empty arg was reported
7650 by Simon Josefsson in

7653 * Makefile.maint (www-gnu): New macro.
7654 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
7655 the location has moved.
7657 2002-12-02 Martin Frydl <martin@systinet.com>
7659 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
7660 \(.*\) match is too long and there is something more to be checked.
7661 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
7663 2002-11-15 Akim Demaille <akim@epita.fr>

7668 From Paul Eggert.
7669 * config/move-if-change: Indenting changes.
7670 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
7671 * configure.ac (AM_INIT_AUTOMAKE): here.
7672 Require 1.7.1.
7674 2002-11-14 Akim Demaille <akim@epita.fr>
7676 Version 2.55.
7678 * config/config.guess, config/config.sub, config/install-sh:
7679 Update from masters.
7681 2002-11-14 Akim Demaille <akim@epita.fr>
7683 * Makefile.maint: Sync with Bison, i.e.:
7684 (po-check): Scan .l and .y files instead of the
7685 .c and the .h files that they generate. This fixes the bug
7686 reported by Tim Van Holder in:
7687 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7688 Look for N_ as well as for _. Try to avoid matching #define for
7689 N_ and _.
7690 From Paul Eggert.
7692 2002-11-14 Akim Demaille <akim@epita.fr>
7694 * doc/autoconf.texi (C Compiler): Compiling several files at once.
7695 From Paul Eggert and Albert Chin-A-Young.
7697 2002-11-14 Akim Demaille <akim@epita.fr>
7699 * doc/autoconf.texi (C Compiler): Solitary backslashes.
7700 From Paul Eggert and Albert Chin-A-Young.
7702 2002-11-14 Kevin Ryde <user42@zip.com.au>
7704 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
7705 than assigning in main, to avoid HP cc +O3 optimizing it away.
7707 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
7709 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
7710 option. Process --recheck after parsing all options. Pass -q
7711 option to configure on --recheck.
7712 (AC_OUTPUT): Pass -q from configure to config.status.
7713 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
7714 arguments to record.
7715 * doc/autoconf.texi (config.status Invocation): Document
7716 config.status -q option.
7718 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
7720 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
7721 Makefile.in if Makefile.am exists.
7722 (output): Strip `.am' from Makefiles. Don't
7723 output AC_CONFIG_FILES if no Makefiles were found.
7725 2002-11-07 Akim Demaille <akim@epita.fr>
7727 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
7728 (local_updates): New.
7729 * Makefile.maint: Update, from CVS Bison.
7730 (local_updates): New.
7732 2002-11-06 Akim Demaille <akim@epita.fr>
7734 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
7735 declaration in extern "C" too.
7736 Reported by Roberto Bagnara.
7738 2002-11-06 Akim Demaille <akim@epita.fr>
7740 * tests/torture.at (Configuring subdirectories): Don't use grep
7741 -w.
7742 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
7743 Reported by Ezra Peisach.
7745 2002-11-05 Akim Demaille <akim@epita.fr>
7747 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
7748 Remove.
7749 We _have_ to stop using the old compatibility scheme that tried to
7750 avoid useless backslashes because Libtool 1.4.3 contains a
7751 AC_DEFINE([error_t], [int],
7752 [Define to a type to use for \`error_t' if it is not
7753 otherwise available.])
7754 We _have_ to quote the single quote and backslashes with \. The
7755 old compatibility scheme saw that ` was backslashed, and therefore
7756 did not quote the single quote. Hence before this patch, Autoconf
7757 was not compatible with Libtool.
7759 2002-11-04 Paul Eggert <eggert@twinsun.com>
7761 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
7762 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
7763 LC_NAME, LC_PAPER, LC_TELEPHONE.
7764 * doc/autoconf.texi (Special Shell Variables): Mention those vars.
7766 2002-11-04 Akim Demaille <akim@epita.fr>
7768 Version 2.54c.
7770 * Makefile.maint (update, cvs-update, po-update, do-po-update):
7771 New.
7772 * config/texinfo.tex: Update.
7774 2002-11-03 Akim Demaille <akim@epita.fr>
7776 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
7777 from...
7778 (&autoreconf): here.

8089 2002-10-22 Akim Demaille <akim@epita.fr>
8091 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

8095 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
8096 strings.
8098 2002-10-22 Akim Demaille <akim@epita.fr>
8100 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

8147 longer required can still cause errors.
8148 Reported by Alexandre Duret-Lutz.
8150 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
8151 to frozen files in @ARGV, as @ARGV must remain being a list of

8153 (&files_to_options): New function.
8154 (&freeze): Use &error.
8155 (&up_to_date): If a file that was included according to the cache
8156 is no longer there, then the output is out dated.

8158 --force is given.
8159 * tests/tools.at (autom4te cache): New.
8161 2002-10-16 Akim Demaille <akim@epita.fr>

8168 that error messages can be easily located, and use GNU Make
8169 format, so that Emacs' compile mode understands us.
8170 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8171 if some file was changed instead of `print'.
8172 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

8206 file name to enable parallel executions.
8207 From Sam Varshavchik.
8209 2002-10-08 Akim Demaille <akim@epita.fr>
8211 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8212 aclocal invocation, as Gettext macros might not be visible to
8213 aclocal.
8214 Instead of blindly running autopoint, scan configure.ac (not the
8215 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8216 Reported by Paul D. Smith.
8218 2002-10-08 Paul Eggert <eggert@twinsun.com>
8220 Work around problems found when POSIXLY_CORRECT=1 is set.
8221 None of this seems to have anything to do with POSIX, really,
8222 but it's how Perl getopt works.
8223 * bin/autom4te.in (parse_args): Configure GetOpt with
8224 "permute", too.
8225 * doc/autoconf.texi (Invoking autom4te):
8226 --warning -> --warnings.

8248 * tests/torture.at (Configuring subdirectories): Be robust to
8249 users who use config.site to require for a cache: in this case,
8250 the two last configure runs, using two different sets of
8251 arguments, trigger a legitimate error.
8253 2002-09-28 Akim Demaille <akim@epita.fr>

8269 (tm_zone): Move their rules to...
8270 * lib/autoconf/types.m4: here, using AN_ macros.
8271 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
8272 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)

8274 * lib/autoconf/programs.m4: here.
8275 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)

8279 2002-09-28 Akim Demaille <akim@epita.fr>
8281 * lib/autoconf/autoscan.m4: New file.
8282 * lib/autoconf/autoconf.m4: Include it.

8285 * lib/autoconf/headers.m4: Similarly with headers.
8286 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
8287 (.m4.m4f): Don't pass --prepend-include, since that's done by
8288 tests/autom4te itself.
8289 * lib/autoscan/Makefile.am: Include freeze.mk.
8290 (autoscan.list): New target --this file is no longer a source.
8291 (autoscan.pre): New file.
8293 2002-09-28 Akim Demaille <akim@epita.fr>
8295 * bin/autoscan.in (@kinds): Make them singular.
8296 Adjust all uses.
8297 (&init_tables): When --debug, report the list of rules to ease
8298 tracking changes in autoscan.list.
8299 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8301 2002-09-28 Akim Demaille <akim@epita.fr>
8303 * lib/autoscan/functions, lib/autoscan/headers,
8304 * lib/autoscan/identifiers, lib/autoscan/makevars,
8305 * lib/autoscan/programs: Merge into...
8306 * lib/autoscan/autoscan.list: this.
8307 * bin/autoscan.in (&init_tables): Adjust.
8309 2002-09-28 Akim Demaille <akim@epita.fr>
8311 * lib/autoscan/functions, lib/autoscan/headers,
8312 * lib/autoscan/identifiers, lib/autoscan/makevars,
8313 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
8314 `functions' line is now prefixed with `function:'.
8315 * bin/autoscan.in (&init_tables): Adjust.
8317 2002-09-28 Akim Demaille <akim@epita.fr>
8319 From now on, autoscan files must always map a macro name to a
8320 word: there is no `default' macro for autoscan.
8322 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8323 all.
8324 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8325 explicit.
8327 2002-09-28 Akim Demaille <akim@epita.fr>
8329 * bin/autoscan.in (%c_keywords): Remove.
8330 (&used): Keep only track of the words we might be interested in.
8331 (&output_kind): It is no longer needed to look for non active
8332 checks.
8334 2002-09-27 Akim Demaille <akim@epita.fr>
8336 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

8341 2002-09-27 Akim Demaille <akim@epita.fr>
8343 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
8344 from /tmp.
8345 Thanks to Bill Moseley and Paul Eggert.
8346 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
8347 the tmpdir must be created.
8348 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
8349 dir be in the build tree, instead of $TMPDIR.
8351 2002-09-27 Akim Demaille <akim@epita.fr>
8353 * bin/autoscan.in: Improve the comments.
8354 (&parse_args): Drop obsolete undocumented options.
8355 (&output_kind): Output warnings.
8356 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

8362 Reported by Ralf Corsepius.
8363 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8365 2002-09-26 Akim Demaille <akim@epita.fr>
8367 Single suffix rules and seperated dependencies are not portable.
8369 * doc/autoconf.texi (Installation Directory Variables): Update.
8370 (Limitations of Make): Some about `Single Suffix Rules and
8371 Separated Dependencies'.
8372 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8373 (ifnames, autoscan, autom4te): Un-factor into several rules.
8375 2002-09-25 Paul Eggert <eggert@twinsun.com>
8377 * BUGS (Interoperability bugs): New section. Mention libtool
8378 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
8380 2002-09-24 Paul Eggert <eggert@twinsun.com>
8382 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
8383 make handles suffix-rules differently from GNU make.
8385 * bin/Makefile.am (SUFFIXES, .in): Remove.
8386 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
8387 Move the body of the old .in rule here.
8389 2002-09-16 Akim Demaille <akim@epita.fr>
8391 i960 compilers create `b.out' files by default.
8392 Reported by Ralf Corsepius.
8394 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
8395 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
8397 2002-09-13 Paul Eggert <eggert@twinsun.com>
8399 * doc/autoconf.texi (Particular Headers): Remove obsolete
8400 reference to `struct timezone' in the description of
8401 AC_HEADER_TIME.
8403 2002-09-13 Akim Demaille <akim@epita.fr>
8405 Version 2.54.
8407 * config/config.sub, config/config.guess: Update.
8408 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
8409 * Makefile.am: Adjust.
8411 2002-09-13 Akim Demaille <akim@epita.fr>
8413 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
8414 reading config.log when the compiler is rejected.
8415 Suggested by Guido Draheim.
8417 2002-09-13 Akim Demaille <akim@epita.fr>
8419 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8420 (chdir_init) might hang when stat'ing mounted directories.
8421 Reported by Vance Shipley.
8423 2002-09-12 Akim Demaille <akim@epita.fr>
8425 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8426 the lists.
8428 2002-09-12 Akim Demaille <akim@epita.fr>
8430 * doc/autoconf.texi (Defining Symbols): Present two different
8431 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
8432 difference between 1 argument calls, and 2-3 argument calls.
8434 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
8436 * doc/autoconf.texi: Review grammar and punctuation.
8438 2002-09-11 Paul Eggert <eggert@twinsun.com>
8440 * doc/autoconf.texi: Fix minor formatting, spelling, and
8441 grammatical typos.
8442 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8443 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8444 is obsolescent.
8446 2002-09-11 Akim Demaille <akim@epita.fr>
8448 * doc/autoconf.texi (Questions): Rename as...
8449 (FAQ): this.
8450 (Defining Directories): New.
8452 2002-09-09 Akim Demaille <akim@epita.fr>
8454 * doc/autoconf.texi (Making testsuite Scripts): Update.
8455 Suggested by Nishio Futoshi.
8457 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8459 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8460 plain `@' is wanted.
8462 2002-09-09 Akim Demaille <akim@epita.fr>
8464 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8465 `duplicates', since the algorithm was too naive and could keep
8466 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8467 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8468 Reported by Ralf Corsepius.
8469 * tests/torture.at (Configuring subdirectories): Exercise these
8470 cases.
8472 2002-09-09 Akim Demaille <akim@epita.fr>
8474 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
8475 looking for a replacement file.
8476 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8477 directory is relative.
8478 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8479 directory definition.
8480 Reported by Andreas Schwab and Jim Meyering.
8482 2002-09-06 Akim Demaille <akim@epita.fr>
8484 * doc/autoconf.texi (Setting Output Variables): Clarify what
8485 precious variables are.
8486 Suggested by Pontus Skoeld.
8488 2002-09-05 Akim Demaille <akim@epita.fr>
8490 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8491 (ifnames, autoscan, autom4te): Since we don't only depend on
8492 configure.ac variables (such as VERSION etc.), but also on prefix
8493 and so forth, depend on Makefile, not configure.ac.
8494 Reported by Alexandre Duret-Lutz.
8495 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8497 2002-09-05 Kevin Ryde <user42@zip.com.au>
8499 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8500 doesn't seem to be confined to ia64, just say "some versions".
8502 2002-09-04 Akim Demaille <akim@epita.fr>
8504 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8505 Automake 1.6c.
8506 * Makefile.am (maintainer-clean-local): Remove.
8507 (MAINTAINERCLEANFILES): Remove COPYING.
8509 2002-09-03 Paul Eggert <eggert@twinsun.com>
8511 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8512 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8513 Brinkmann.
8515 2002-09-03 Akim Demaille <akim@epita.fr>
8517 * configure.ac: Bump to 2.53d.
8518 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8519 as of today, on Automake's team suggestion.
8521 2002-09-03 Akim Demaille <akim@epita.fr>
8523 Version 2.53c.
8525 2002-09-02 Akim Demaille <akim@epita.fr>
8527 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8528 SITE_MACRO_DIR.
8529 * configure.ac: Disable SITE_MACRO_DIR.
8531 2002-09-02 Jim Meyering <meyering@lucent.com>
8533 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8534 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8535 Also, tweak grammar: s/make sure to/be sure to/.
8537 2002-09-02 Paul Eggert <eggert@twinsun.com>
8539 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8540 directory names are generally preferable to physical names.
8542 2002-09-02 Akim Demaille <akim@epita.fr>
8544 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8545 Reported by Raja R. Harinath.
8546 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8547 * bin/autoupdate.in: Use error instead of die.
8549 2002-09-01 Paul Eggert <eggert@twinsun.com>
8551 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8552 ordinary shell concatenation rather than echo+tr+sed command that
8553 runs afoul of a long-line-related sed bug in Solaris 8.
8555 * bin/autoheader.in (parse_args): --warning -> --warnings.
8557 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8558 stdout, as traditional "ls" does.
8559 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8560 _AC_COMPILER_EXEEXT_O): Likewise.
8561 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8563 * bin/autoconf.as: Add --prepend-include option. This patch was
8564 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8565 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8567 * bin/autoconf.in, configure: Regenerate.
8569 * doc/autoconf.texi (Special Shell Variables): Mention
8570 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8572 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8573 MAILPATH and set PS1, PS2, PS4 to default values, to work
8574 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8575 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8576 the Autoconf documentation specifies; fall back to "unset" only if
8577 this fails. Use a shell for-loop for this rather than an m4 loop,
8578 to shorten the output script.
8580 2002-08-30 Paul Eggert <eggert@twinsun.com>
8582 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8583 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8584 for the CDPATH problem. Document PWD.
8585 (Limitations of Builtins): Document the problem that "cd $foo" and
8586 "ls $foo" may refer to different directories in shells conforming
8587 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8588 example, since the old example is now out of date.
8590 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8591 FOO" and "ls FOO" talk about different directories; this catches
8592 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8593 spaghetti.
8595 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8596 of rolling our own unset.
8597 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8598 in practice we needn't worry about CDPATH if unset doesn't work.
8600 * Makefile.in, aclocal.m4, bin/Makefile.in,
8601 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8602 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8603 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8604 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8605 tests/Makefile.in: Regenerate with Automake 1.6.3.
8607 * config/config.guess, config/config.sub, config/mkinstalldirs:
8608 Update.
8610 * configure: Regenerate with self.
8612 2002-08-30 Kevin Ryde <user42@zip.com.au>
8614 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8615 default output.
8617 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8619 * bin/autom4te.in (Request::load): Correctly test for "do" read
8620 failure.
8622 2002-08-29 Akim Demaille <akim@epita.fr>
8624 * lib/Autom4te/General.pm (&xqx): New.
8625 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8626 hand, which is not portable.
8627 (&error): New.
8628 * bin/autom4te.in: Use them.
8629 Use &error instead of die.
8630 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8631 Adjust.
8633 2002-08-17 Paul Eggert <eggert@twinsun.com>
8635 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8636 default list of compilers to try, since it was long ago superseded
8637 by the ksh fc builtin. Suggested by Steven G. Johnson.
8639 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8641 * doc/autoconf.texi (Invoking autom4te): End the option table,
8642 fixing a bug introduced by the previous patch.
8643 (Limitations of Make): Add a 'target lookup' subentry in the
8644 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8646 2002-07-29 Mark D. Roth <roth@feep.net>
8648 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8649 options and use $AUTOM4TE_PATH.
8650 * doc/autoconf.texi: Remove documentation of autom4te
8651 --include-envvar and --site-macro-subdir options and document
8652 use of $AUTOM4TE_PATH.
8653 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8654 arguments from each language section.
8656 2002-07-29 Paul Eggert <eggert@twinsun.com>
8658 * doc/install.texi: Include copyright symbol in copyright notice.
8660 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8661 Replace with:
8662 (AM_MAKEINFOFLAGS): New macro.
8663 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8664 * Makefile.am (INSTALL): Use the new macros.
8665 Use -o rather than --output, since "missing" does not grok --output.
8667 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8669 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8670 comments do not always work. Never trust the exit status of
8671 `make -k'.
8673 2002-07-24 Kevin Ryde <user42@zip.com.au>
8675 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8676 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8678 2002-07-23 Paul Eggert <eggert@twinsun.com>
8680 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8681 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8682 apparently treats PATH="nonexistent" as if it contained ".".
8683 Bug reported by Stefan `Sec' Zehl.
8685 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8687 * doc/autoconf.texi (Limitations of Make): Mention the special
8688 handling of the obj/ directory by BSD make.
8690 2002-07-20 Kevin Ryde <user42@zip.com.au>
8692 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
8693 backslashes.
8695 2002-07-19 Akim Demaille <akim@epita.fr>
8697 * doc/autoconf.texi (Function Portability): `exit'.
8698 (Programming in M4sh): Ethymology of M4sh.
8700 2002-07-19 Akim Demaille <akim@epita.fr>
8702 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
8704 2002-07-18 Akim Demaille <akim@epita.fr>
8706 Version 2.53b.
8708 2002-07-18 Akim Demaille <akim@epita.fr>
8710 * config/config.guess, config/config.sub: Update.
8712 2002-07-18 Akim Demaille <akim@epita.fr>
8714 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
8715 Automake's parts.
8717 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
8718 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
8719 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
8721 2002-07-18 Akim Demaille <akim@epita.fr>,
8722 Alexandre Duret-Lutz <duret_g@epita.fr>
8724 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
8725 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
8727 2002-07-17 Russ Allbery <rra@stanford.edu>
8729 * doc/autoconf.texi (Initializing configure): Clarify the
8730 description of the tarname default.
8732 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
8734 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
8735 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
8736 latter was not run.
8738 2002-07-17 Akim Demaille <akim@epita.fr>
8740 * lib/Autom4te/General.pm (find_file): Browse the directories in
8741 the order they are given.
8743 2002-07-17 Akim Demaille <akim@epita.fr>
8745 * tests/wrapsh.as, tests/wrappl.as: Merge into...
8746 * tests/wrapper.as: this.
8747 * tests/Makefile.am, configure.ac: Adjust.
8749 2002-07-17 Mark D. Roth <roth@feep.net>
8751 * configure.ac: Add --enable-site-macro-dir option.
8752 * bin/Makefile.am: Expand @SITE_MACRO_DIR@.
8753 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
8754 --site-macro-subdir options.
8755 * bin/autoconf.in: Add --prepend-include option.
8756 * bin/autoheader.in: Add --prepend-include option.
8757 * bin/autoreconf.in: Add --prepend-include option.
8758 * bin/autoscan.in: Add --prepend-include option.
8759 * bin/autoupdate.in: Add --prepend-include option.
8760 * doc/autoconf.texi: Document use of $AC_MACRO_PATH and site
8761 macro directory, remove note that include path directories are

8809 2002-06-27 Paul Eggert <eggert@twinsun.com>
8811 * config/install-sh: Quote $src. Prefer || to test's -o option,
8812 as per "Limitations of Builtins".
8813 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
8814 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.

8844 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>

8847 of the cache should not depend on the name under which autom4te
8848 was installed.

8856 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
8858 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
8859 _AC_LANG_PROGRAM_C_F77_HOOKS.
8861 2002-06-07 Akim Demaille <akim@epita.fr>

8867 AC_FUNC_FNMATCH_GNU.
8869 2002-06-07 Akim Demaille <akim@epita.fr>
8871 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
8872 Rosetta Stone for Unix.
8874 2002-06-07 Akim Demaille <akim@epita.fr>
8876 * bin/autom4te.in (warn_forbidden): When rejecting a token,
8877 suggest m4_pattern_allow.
8878 Suggested by Adam J. Richter.
8880 2002-06-07 Akim Demaille <akim@epita.fr>

8885 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

8898 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
8899 if ln doesn't work.

8939 version of Autoconf that is discussed.
8941 2002-05-22 Paul Eggert <eggert@twinsun.com>
8943 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
8944 from the default list of compilers to try. Suggested by
8945 Kate Hedstrom.
8946 * NEWS: Document the above.
8947 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
8949 2002-05-17 Paul Eggert <eggert@twinsun.com>
8951 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
8952 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
8953 This improves on an earlier suggestion by H. Peter Anvin.
8955 2002-05-16 Paul Eggert <eggert@twinsun.com>
8957 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
8958 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
8959 Both macros now accept an optional source-dir arg.
8960 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
8962 * NEWS: Document this.
8963 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
8965 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
8966 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
8967 not for GNU extensions; this undoes part of the 2000-11-03 change,
8968 reverting to 2.13-compatible behavior.
8969 Add new optional argument DIR.
8970 (AC_FUNC_FNMATCH_GNU): New macro.
8972 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
8974 2002-05-08 Paul Eggert <eggert@twinsun.com>
8976 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
8977 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
8978 and it causes a 'test' syntax error if it fails.
8979 Bug reported by Stephen Gildea.
8981 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8982 If prototypes are supported, use them to check this at compile-time,
8983 instead of trying to check it at run-time. If we must do a run-time
8984 check, assume that setvbuf is standard when cross-compiling, as
8985 nonstandard setvbuf occurs only on ancient and unlikely hosts.
8986 Bug reported by Paul D. Smith.
8988 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
8989 argument specifying location of getloadavg.c. This removes a
8990 FIXME. This idea was taken from Jim Meyering's implementation in
8991 textutils.
8992 * doc/autoconf.texi (Particular Functions): Document this.
8993 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
8994 that's what the code does; this fixes a bug reported by
8995 Paul D. Smith.
8997 2002-05-03 Akim Demaille <akim@epita.fr>
8999 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9000 autopoint instead of gettextize.
9001 ($uses_alocal): Rename as...
9002 ($uses_aclocal): this.
9003 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9004 Suggested by Bruno Haible.
9006 2002-05-03 Akim Demaille <akim@epita.fr>
9008 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9010 2002-04-29 Paul Eggert <eggert@twinsun.com>
9012 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9013 files to be 1 second older; just set them to be the same time.
9014 Also, sleep 1 second after the first aclocal, to work around
9015 problems with sub-second time stamps on the input files.
9017 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9019 * doc/autoconf.texi: Mention "set -e -x" lossage
9020 under node "Limitations of Builtins".
9022 2002-04-29 Akim Demaille <akim@epita.fr>
9024 * doc/install.texi: Better wording for setting variables when
9025 running configure.
9026 From Christian Cornelssen.
9028 2002-04-29 Akim Demaille <akim@epita.fr>
9030 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9031 of lack of $LINENO support, then the test will compare the $LINENO
9032 in testsuite vs. the lineno in the test file. This is wrong, of
9033 course.
9034 Be sure to protect it.
9035 Reported by Patrick Welche.
9037 2002-04-25 Akim Demaille <akim@epita.fr>
9039 * doc/autoconf.texi (Obsolete Macros): Typo.
9040 Reported by Vladimir Volovich.
9042 2002-04-25 Akim Demaille <akim@epita.fr>
9044 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9045 than some of the input files, hence, on the second run of aclocal,
9046 if some of its input are younger, make them older.
9047 Suggested by Paul Eggert.
9049 2002-04-25 Akim Demaille <akim@epita.fr>
9051 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9052 Thanks to Paul Eggert.
9054 2002-04-25 Akim Demaille <akim@epita.fr>
9056 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9057 and ac_subst_vars be sh variables containing the list of
9058 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9059 DEFAULT diversion.
9060 (_AC_INIT_PREPARE): Use them to log them.
9061 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9062 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9063 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9064 _AC_SUBST_FILES and _AC_SUBST_VARS.
9065 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9067 2002-04-24 Akim Demaille <akim@epita.fr>
9069 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9070 autoheader, so that automake does not complain about a missing
9071 config.h.in that was to be created.
9073 2002-04-23 Akim Demaille <akim@epita.fr>
9075 * bin/autoheader.in (parse_args): --warning takes an argument.
9076 Fixes PR/220.
9078 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
9080 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

9099 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
9100 Fixes false failures on Darwin.

9125 Minor spelling and grammar fixes.
9127 * doc/autoconf.texi: Follow the outline suggested in the GNU
9128 Sample Texts sections of the Texinfo 4.2 manual. Most
9129 importantly, this makes sure that the copyright notices appear in
9130 all output formats. You probably need Texinfo 4.2 to generate
9131 the manual now.

9157 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
9159 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

9186 * lib/autotest/general.m4 (AT_INIT): Likewise.
9187 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

9191 Use this M4sh to generate Autoconf's shell scripts.
9193 * tests/wrapsh.as: New, precursor of wrapsh.in.

9236 Don't use the KILL diversion, as it kills spurious output, which
9237 results in failures being hidden.

9248 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
9249 expanded if $# <= 2.
9251 * bin/autoreconf.in (autoreconf): Run automake after rerunning
9252 aclocal.
9254 2002-04-03 Akim Demaille <akim@epita.fr>
9256 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
9257 (_AC_COMPILER_EXEEXT_REJECT): New.
9258 Also recognize *.bb and *.bbg as compilation byproducts.
9259 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
9260 (_AC_COMPILER_OBJEXT): Use them.
9261 Fixes Debian #138666.
9263 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9265 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
9267 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
9268 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9269 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
9270 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
9271 (AC_C_CONST): Same.
9272 (AC_C_INLINE): Same.
9273 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
9274 * doc/autoconf.texi, NEWS: Document.
9275 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
9276 AC_C_CROSS.
9278 2002-04-02 Akim Demaille <akim@epita.fr>
9280 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
9281 _AS_MKDIR_P_PREPARE.
9283 2002-03-28 Kevin Ryde <user42@zip.com.au>
9285 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9286 to avoid versions of HP C which don't allow that.
9288 2002-03-27 Paul Eggert <eggert@twinsun.com>
9290 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9291 (AS_SHELL_SANITIZE): Invoke it.
9292 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
9294 2002-03-26 Akim Demaille <akim@epita.fr>
9296 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
9298 2002-03-26 Akim Demaille <akim@epita.fr>
9300 * doc/autoconf.texi (Introduction): The GNATS base moved.
9302 2002-03-25 Paul Eggert <eggert@twinsun.com>
9304 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9305 as POSIX requires, as it doesn't work with Zsh.
9306 * doc/autoconf.texi (Assignments): Document the problem.
9308 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9310 * doc/autoconf.texi (Limitations of Make): Mention more issue
9311 about VPATH, overriding of macros in sub-makes, and handling of
9312 SHELL.
9314 2002-03-21 Paul Eggert <eggert@twinsun.com>
9316 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9317 problem with here-document buffer boundaries.
9319 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9320 when reinvoking the shell, to work around problems with installers
9321 who put strange things like "cd" commands in their environments.
9323 2002-03-19 Akim Demaille <akim@epita.fr>
9325 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9326 From Aaron Ucko.
9328 2002-03-19 Akim Demaille <akim@epita.fr>
9330 * bin/autoscan.in (scan_file): Specify the location in `&used'
9331 invocations.
9332 From Nicolas Joly.
9334 2002-03-19 Akim Demaille <akim@epita.fr>
9336 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
9337 From Nishio Futoshi.
9339 2002-03-19 Akim Demaille <akim@epita.fr>
9341 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9343 2002-03-18 Paul Eggert <eggert@twinsun.com>
9345 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9346 (Limitations of Usual Tools): Add mkdir section.
9348 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9349 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9350 back on AS_DIRNAME to compute prefixes otherwise; this is
9351 roughly what mkinstalldirs does. That way, we need not have
9352 our own filename disassembler. The old disassembler did not
9353 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9355 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9356 Create at_test_all by a series of assignments,
9357 not by a single assignment of a long string. The latter causes ksh
9358 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9359 presumably because of a buffer overrun.
9361 2002-03-14 Paul Eggert <eggert@twinsun.com>
9363 * lib/autotest/general.m4 (at_times_skip):
9364 Renamed from at_times. Now a boolean.
9365 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9366 says 'times: not found'.
9368 2002-03-14 Akim Demaille <akim@epita.fr>
9370 * bin/autoreconf.in (&study_gettextize): New.
9371 (&autoreconf): Handle newest gettextize.
9372 Rerun aclocal if needed.
9373 Suggested by Andreas Schwab.
9375 2002-03-13 Akim Demaille <akim@epita.fr>
9377 * doc/autoconf.texi (Special Shell Variables): More about IFS.
9379 2002-03-13 Akim Demaille <akim@epita.fr>
9381 * doc/autoconf.texi (Header Portability): New.
9382 Add information about stdint.h and inttypes.h from Paul Eggert.
9384 2002-03-13 Akim Demaille <akim@epita.fr>
9386 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9387 -p'.
9388 From Bob Proulx.
9390 2002-03-12 Akim Demaille <akim@epita.fr>
9392 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9393 m4_require.
9395 2002-03-11 Andreas Schwab <schwab@suse.de>
9397 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9398 does not do it if --with-lispdir is given.
9400 2002-03-08 Akim Demaille <akim@epita.fr>
9402 Version 2.53.
9404 2002-03-08 Akim Demaille <akim@epita.fr>
9406 * doc/autoconf.texi (Subdirectories): Clarify that the
9407 subdirectory should exist.
9409 2002-03-08 Akim Demaille <akim@epita.fr>
9411 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9413 2002-03-08 Akim Demaille <akim@epita.fr>
9415 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9416 aliases the actual variables, and modifications of the former
9417 affect the latter.
9419 2002-03-08 Akim Demaille <akim@epita.fr>
9421 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9422 because of C-c: have m4 output in tmp files, then mv them.
9424 2002-03-08 Akim Demaille <akim@epita.fr>
9426 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
9427 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
9428 * bin/ifnames.in: Copyright update.
9430 2002-03-08 Akim Demaille <akim@epita.fr>
9432 * doc/autoconf.texi (Invoking autom4te): New.
9434 2002-03-05 Akim Demaille <akim@epita.fr>
9436 * doc/autoconf.texi (Specifying Names): Clarification suggested by
9437 Kevin Ryde.
9439 2002-03-05 Akim Demaille <akim@epita.fr>
9441 Version 2.52i.
9443 2002-03-04 Akim Demaille <akim@epita.fr>
9445 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
9446 * lib/autoconf/general.m4 (AC_INIT): More informative error
9447 message for LIBOBJ.
9449 2002-03-04 Akim Demaille <akim@epita.fr>
9451 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
9452 parallel builds.
9454 2002-03-04 Akim Demaille <akim@epita.fr>
9456 * doc/autoconf.texi (Transforming Names): Equality between target
9457 and host is irrelevant.
9458 (Specifying Names, Canonicalizing): Remove all references to the
9459 backward compatibility hooks. Rather, collect them all into...
9460 (Hosts and Cross-Compilation): this new section.
9461 * doc/install.texi (System Type): Ditto.
9462 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9463 that `--host' implies cross-compilation.
9465 2002-03-04 Akim Demaille <akim@epita.fr>
9467 * doc/autoconf.texi (Evaluation Macros): New.
9468 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9469 useless.
9470 (_m4_foreach): Define the variant with immediate evaluation so
9471 that it contains exactly the items, not an expression which
9472 evaluation is the current item.
9473 (m4_re_string, m4_re_word): Don't over quote them.
9475 2002-03-04 Akim Demaille <akim@epita.fr>
9477 Instead of having stacking `shift's evaluated at the end, let
9478 `foreach' loops immediately evaluate them.
9480 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9481 $*. This is the n-th time I change my mind, but hopefully this is
9482 the last...
9483 (m4_lquote): New.
9484 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9485 efficient.
9486 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9487 it was only a hack for m4_text_wrap.
9488 (m4_car2): Remove, replaced by...
9489 (m4_cdr): New.
9490 (_m4_foreach): Adjust.
9491 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9492 m4_bpatsubst for clarification.
9494 2002-03-04 Akim Demaille <akim@epita.fr>
9496 * doc/autoconf.texi (Changequote is Evil): New.
9498 2002-03-03 Kevin Ryde <user42@zip.com.au>
9500 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
9501 on old systems like SunOS.
9503 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
9505 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9506 lib/autoconf/functions.m4, lib/autoconf/general.m4,

9514 message to be sent.
9516 2002-02-28 Kevin Ryde <user42@zip.com.au>

9520 2002-02-25 Akim Demaille <akim@epita.fr>
9522 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
9523 From Akinori Musha.
9525 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
9527 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
9528 translate \r\n to \n.
9530 2002-02-07 Akim Demaille <akim@epita.fr>
9532 Version 2.52h.
9534 2002-02-07 Akim Demaille <akim@epita.fr>
9536 Fix Autoconf PR/209.
9537 Also reported by Frank Denis.
9539 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
9541 2002-02-07 Akim Demaille <akim@epita.fr>
9543 Fix Autoconf PR/207:
9544 AC_PREFIX_PROGRAM fails with dashed program names
9546 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
9547 variable when looking for the prefix program.
9548 Now it also works for shell variables.
9550 2002-02-07 Akim Demaille <akim@epita.fr>
9552 * doc/autoconf.texi (Limitations of Builtins): More about
9553 case/esac.
9555 2002-02-06 Akim Demaille <akim@epita.fr>
9557 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
9558 case/esac, some shells don't support it.
9559 Reported by Zack Weinberg.
9560 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
9562 2002-02-06 Akim Demaille <akim@epita.fr>
9564 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
9565 sure not to introduce newlines in at_groups.
9566 * lib/autotest/Makefile.am (autotest.m4f): Typo.
9568 2002-02-06 Akim Demaille <akim@epita.fr>
9570 * tests/torture.at (Configuring subdirectories): Skip if aclocal
9571 is not available.
9573 2002-02-05 Paul Eggert <eggert@twinsun.com>
9575 * doc/autoconf.texi (Specific Compiler Characteristics):
9576 Describe HP-UX cc bug workaround more accurately.
9577 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
9578 not unsigned long.
9579 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
9580 cross-compilers, too. This undoes some of the most recent change
9581 to this file.
9583 2002-02-05 Akim Demaille <akim@epita.fr>
9585 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
9586 to make sure they are up to date when `check' is run.
9588 2002-02-05 Akim Demaille <akim@epita.fr>
9590 * doc/autoconf.texi (Making testsuite Scripts): Document
9591 package.m4.
9593 2002-02-05 Akim Demaille <akim@epita.fr>
9595 * lib/freeze.mk: New.
9597 2002-02-05 Akim Demaille <akim@epita.fr>
9599 Implement `autom4te --freeze'.
9601 * bin/autom4te.in (&freeze): New.
9602 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9603 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9605 2002-02-05 Akim Demaille <akim@epita.fr>
9607 * bin/autom4te.in (&parse_args): Implement `frozen files are
9608 optional are the sum of the previous files on the command line'.
9609 Also, pass `--reload-state=' on them, so...
9610 (handle_m4): don't.
9611 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9612 (M4sh): Rely on M4sugar.
9613 (Autotest, M4sh, M4sugar): Use frozen files.
9615 2002-01-31 Akim Demaille <akim@epita.fr>
9617 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
9618 * doc/autoconf.texi (Initializing configure): Adjust.
9620 2002-01-30 Akim Demaille <akim@epita.fr>
9622 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
9623 alphanumeric to `-' instead of `_'.
9625 2002-01-30 Akim Demaille <akim@epita.fr>
9627 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
9628 for plain code, the other for cross-compilation code. The latter
9629 is now run with GCC only.
9630 * doc/autoconf.texi (Compilers and Preprocessors): New.
9632 2002-01-30 Akim Demaille <akim@epita.fr>
9634 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
9635 values.
9636 * doc/autoconf.texi (Initializing configure): Explain how to
9637 change AC_INIT default values.
9639 2002-01-29 Akim Demaille <akim@epita.fr>
9641 * tests/torture.at (Configuring subdirectories): Use configure.in,
9642 so that aclocal 1.4 works.
9643 Reported by Alexandre Duret-Lutz and Larry Schmitt.
9645 2002-01-28 Akim Demaille <akim@epita.fr>
9647 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9648 needs an argument.
9650 2002-01-28 Akim Demaille <akim@epita.fr>
9652 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9653 AUTOTEST_PATH *after* it was set.
9654 Don't put `.' in the PATH: the user should be precise and `./' if
9655 needed. In addition, given that the test suite does some `cd', if
9656 `.' is in the path, the `tested programs' sections will report
9657 programs found in the test suite's directory, while during the
9658 tests (performed in their own directory), these programs are no
9659 longer visible. In other words, the results is confusing and
9660 useless.
9661 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
9663 2002-01-24 Akim Demaille <akim@epita.fr>
9665 Version 2.52g.
9667 2002-01-24 Akim Demaille <akim@epita.fr>
9669 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
9670 * doc/autoconf.texi: Finally add Akim as an author.
9672 2002-01-24 Akim Demaille <akim@epita.fr>
9674 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
9675 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
9676 Bourne. Use /bin/sh.
9677 From Andreas Buening.
9679 2002-01-24 Akim Demaille <akim@epita.fr>
9681 * config/config.guess, config/config.sub, config/texinfo.tex:

9690 * config/strip.m4: Remove, to ease sync'ing with any version of
9691 Automake.
9693 2002-01-24 Akim Demaille <akim@epita.fr>
9695 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
9696 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
9697 Reported by Geir Ove Myhr.
9699 2002-01-21 Akim Demaille <akim@epita.fr>
9701 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
9703 2002-01-21 Akim Demaille <akim@epita.fr>
9705 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
9706 message on invalid options.
9707 * bin/autom4te.in (parse_args): Don't use
9708 Autoconf::General::getopt with non valid options.
9710 2002-01-17 Jim Meyering <meyering@lucent.com>
9712 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
9713 $ac_cv_exeext so we don't use an old, invalid, cached value.
9715 2002-01-11 Akim Demaille <akim@epita.fr>
9717 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
9718 Meyering.
9719 * doc/autoconf.texi (Function Portability): Document the strnlen
9720 limitation.
9721 (Particular Functions): Document AC_FUNC_STRNLEN.
9722 * lib/autoscan/functions: Adjust.
9724 2002-01-06 Akim Demaille <akim@epita.fr>
9726 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
9727 package.m4, since is really depends upon configure.ac, not
9728 configure.
9729 * doc/autoconf.texi (testsuite Scripts): Adjust.
9730 * tests/Makefile.am (package.m4): New.
9731 EXTRA_DIST it since its a source.
9733 2002-01-06 Akim Demaille <akim@epita.fr>
9735 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
9736 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
9737 and PACKAGE_BUGREPORT from here...
9738 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
9739 arguments.
9740 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
9741 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
9742 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
9743 * tests/tools.at (autoheader): Adjust.
9744 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
9746 2002-01-06 Akim Demaille <akim@epita.fr>
9748 * bin/autoscan.in (scan_file): Use `&used'.
9750 2002-01-03 Akim Demaille <akim@epita.fr>
9752 * doc/autoconf.texi (Output): Improved wording regarding use of
9753 AC_OUTPUT.
9754 From Olly Betts.
9756 2001-12-18 Kevin Ryde <user42@zip.com.au>
9758 * doc/autoconf.texi (Function Portability): Add notes on sscanf
9759 sometimes needing writable input.
9761 2001-12-17 Jim Meyering <meyering@lucent.com>
9763 * doc/autoconf.texi (New Macros): Tweak wording.
9765 2001-12-14 Akim Demaille <akim@epita.fr>
9767 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
9768 trailing files, don't apply `-rf' to files which might not be
9769 created by configure (core, core.*, and *.core), but just `rm -f'.
9770 Suggested by Jonathan Kamens.
9772 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
9774 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
9776 2001-12-14 Akim Demaille <akim@epita.fr>
9778 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
9780 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
9782 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
9783 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
9784 abs_srcdir, top_srcpath to abs_top_srcdir.
9785 (_AC_OUTPUT_FILES): Adjust.
9786 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
9787 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
9788 * tests/wrappl.in, tests/wrapsh.in: Adjust.
9790 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
9792 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
9793 C/Fortran linking on HP/UX, by extracting the Fortran library
9794 search path from the LPATH line in the $F77 -v output.
9796 2001-12-12 Kevin Ryde <user42@zip.com.au>
9798 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
9799 forbidden file descriptors table.
9801 2001-11-26 Akim Demaille <akim@epita.fr>
9803 * bin/autoscan.in (%c_keywords): Build it at top level.
9804 Map to 1 in order to simplify its uses.
9806 2001-11-26 Akim Demaille <akim@epita.fr>
9808 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
9809 Remove $filepath, useless.
9810 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
9811 variables, they are really part of the tokens.
9812 Split the input line on spaces and then look for tokens.
9813 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
9814 because of `lex$U.$(OBJEXT)'.
9815 (&scan_files): Use "@list" instead of join.
9816 * doc/Makefile.am (CLEANFILES): Add *.fns.
9818 2001-11-26 Akim Demaille <akim@epita.fr>
9820 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
9821 Remove, replaced by...
9822 * tests/wrappl.in: Be common for all the Perl executables.
9823 In particular autoscan and autoheader want -I.
9824 * configure.ac: Adjust.
9825 * lib/autoscan/headers: errno.h is portable.
9827 2001-11-26 Akim Demaille <akim@epita.fr>
9829 * bin/autoscan.in (used): New.
9830 Use it.
9832 2001-11-26 Akim Demaille <akim@epita.fr>
9834 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
9835 directives.
9836 (&scan_sh_file): Remove a duplicate pattern.
9837 (&check_configure_ac): Use long options.
9838 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
9840 2001-11-26 Akim Demaille <akim@epita.fr>
9842 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
9843 Before, having a line containing the opening of a multi line
9844 comment made the whole line be ignored.
9846 2001-11-26 Akim Demaille <akim@epita.fr>
9848 * doc/autoconf.texi (Using an Autotest Test Suite): New.
9849 (testsuite Scripts): Be one of its subsection.
9850 (Autotest Logs): New.
9852 2001-11-26 Akim Demaille <akim@epita.fr>
9854 Test groups are now run two directories deeper.
9856 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
9857 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
9858 at_top_builddir.
9859 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
9860 top_srcdir, builddir and top_builddir.
9861 Use `at_*dir' relatively to the directory containing the
9862 suite, use `*dir' when relatively to the current group dir.
9864 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
9866 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
9867 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
9868 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
9869 spelling errors.
9871 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9873 * doc/autoconf.texi (Using System Type): Add an example of `case
9874 $host' usage so people quit using `case $target' everywhere.
9876 2001-11-22 Akim Demaille <akim@epita.fr>
9878 * doc/autoconf.texi (Installation Directory Variables): Englishoes
9879 spotted by Jim Meyering.
9881 2001-11-16 Paul Eggert <eggert@twinsun.com>
9883 This patch implements a `long double' suggestion by Oliver Kiddle.
9885 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
9886 static, to catch errors if the value isn't known at compile-time
9887 and the compiler supports dynamic arrays. Change its name from
9888 `_array_' to `test_array' to avoid potential name clashes.
9889 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
9890 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
9891 better than double. Catch a bug in GCC 2.95.2 x86.
9892 * doc/autoconf.texi (C Compiler): Document the above.
9893 * NEWS: Likewise.
9895 2001-11-13 Akim Demaille <akim@epita.fr>
9897 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
9898 hand.
9899 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
9901 2001-11-13 Akim Demaille <akim@epita.fr>
9903 * lib/autotest/general.m4 (AT_INIT): After having run the test
9904 group, go back to the initial directory, not to at_suite_dir.
9906 2001-11-13 Akim Demaille <akim@epita.fr>
9908 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
9909 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
9910 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
9911 option.
9912 (AT_CHECK_CONFIGURE): Use absolute paths.
9913 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
9914 The problem is still the old one: there is no means in M4 (that I
9915 know about) to create a defining macro, because there is no means
9916 to create `$1' etc., therefore, the defining macro ``swallows''
9917 all the arguments meant to the defined macro.
9919 2001-11-13 Akim Demaille <akim@epita.fr>
9921 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
9922 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
9923 configure.ac.
9924 * tests/aclocal.m4: Remove, as it is no longer used.
9926 2001-11-13 Akim Demaille <akim@epita.fr>
9928 * lib/autotest/general.m4: Change `tests?' into `groups?' in
9929 variable names when referring to a single test group, or to
9930 `suite' when referring to the whole test suite.
9931 `at_last_test' is removed: m4 compute at_format itself.
9932 (at_stdout, at_stder1, at_stderr): New variables.
9933 (AT_CHECK): Use them.
9935 2001-11-13 Akim Demaille <akim@epita.fr>
9937 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
9938 in PATH.
9939 Create `testsuite.dir/003/run' instead of `testsuite.003'.
9940 Do it as soon as a test fails, don't wait till the end of the test
9941 suite.
9942 Don't remove $as_me.[0-9]*, since these files no longer exist.
9944 2001-11-13 Akim Demaille <akim@epita.fr>
9946 * tests/tools.at: Use absolute paths, since we are no longer run
9947 in place.
9949 2001-11-13 Akim Demaille <akim@epita.fr>
9951 Now that tests are running in their own private dir, there is no
9952 need to list the files to remove at the end of tests groups.
9954 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
9955 (AT_data_files, at_data_files): Remove.
9956 (AT_CLEANUP, AT_DATA): Simplify.
9957 (AT_INIT): Adjust.
9958 Remove the group dir if !debug && !failed.
9959 * tests/atspecific.m4: Adjust.
9961 2001-11-13 Akim Demaille <akim@epita.fr>
9963 Start a new layout for Autotest: `testsuite' creates
9964 `testsuite.dir' in which the at-check-line etc. files are to be
9965 found, and `testsuite.dir/003' where the test group 3 is run.
9967 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
9968 at_check_line_file, at_format, at_test_normalized, at_group_dir
9969 are new variables.
9970 Create the directories.
9971 Use absolute paths for at- files.
9972 (AT_CHECK): Adjust.
9974 2001-11-11 Michael Matz <matz@kde.org>
9976 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
9977 (m4_car2): New.
9978 (m4_car): Properly quote arguments.
9980 2001-11-13 Akim Demaille <akim@epita.fr>
9982 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
9983 with stricter rules on LIBOBJS.
9985 2001-11-12 Paul Eggert <eggert@twinsun.com>
9987 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
9988 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
9989 __PROTOTYPES too.
9991 2001-11-12 Akim Demaille <akim@epita.fr>
9993 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
9995 2001-11-12 Akim Demaille <akim@epita.fr>
9997 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9998 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
9999 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10000 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10001 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10002 specify to what the macro should be defined (typically to 1).
10004 2001-11-12 Akim Demaille <akim@epita.fr>
10006 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10007 From Jim Meyering.
10009 2001-11-12 Akim Demaille <akim@epita.fr>
10011 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10012 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10013 definition used by Automake where LEX is +/- "${missing} lex" and
10014 `missing' itself contains variables.
10016 2001-11-12 Akim Demaille <akim@epita.fr>
10018 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10019 Now that M4sh pushes BODY, the comments were output at the end of
10020 the test suites.
10022 2001-11-08 Akim Demaille <akim@epita.fr>
10024 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10025 that we can trace macros from aclocal.m4.
10026 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10027 obsoleted, and redirect to the former anyway.
10028 Reported by Ralf Corsepius.
10030 2001-11-08 Akim Demaille <akim@epita.fr>
10032 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10033 processed only if present.
10034 * tests/torture.at (Configuring subdirectories): Use autoreconf
10035 instead of successive calls to autoconf.
10036 Add a nonexistent subdirectory to exercise the patch above.
10037 Reported by Ralf Corsepius.
10039 2001-11-08 Kevin Ryde <user42@zip.com.au>
10041 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10042 doesn't accept .S files.
10044 2001-11-07 Akim Demaille <akim@epita.fr>
10046 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
10047 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
10048 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10049 * bin/autom4te.in (warn_forbidden): New.
10050 (handle_output): Use it.
10051 Read m4_pattern_forbid with messages.
10053 2001-11-05 Akim Demaille <akim@epita.fr>
10055 * bin/autom4te.in (--normalize): Remove.
10056 * lib/autom4te.in: Adjust.
10058 2001-11-05 Akim Demaille <akim@epita.fr>
10060 * tests/Makefile.am (testsuite): Rename this target as...
10061 ($(TESTSUITE)): this.
10062 From Nicolas Joly.
10064 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10066 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10067 the --prefix option, also remove it's argument.
10069 2001-11-05 Akim Demaille <akim@epita.fr>
10071 * doc/autoconf.texi (testsuite Invocation): Update.
10072 (Writing testsuite.at): Update.
10074 2001-11-03 Akim Demaille <akim@epita.fr>
10076 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10078 2001-11-03 Akim Demaille <akim@epita.fr>
10080 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10081 (&file_name_is_absolute): New, wrappers around routines from
10082 File::Spec.
10083 Use and export them.
10084 (&find_configure_ac): Optionally take a directory where to look at.
10085 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10086 the arguments.
10087 Default @ARGV to `.', not find_configure_ac.
10088 (&autoreconf): Argument is a directory.
10089 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10090 * doc/autoconf.texi (autoreconf Invocation): Update.
10092 2001-11-03 Akim Demaille <akim@epita.fr>
10094 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10095 (@export_forward_subs): New.
10096 Add basename, dirname, and fileparse.
10097 (@EXPORT): Adjust.
10098 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10099 Don't look for aclocal flags if we already know aclocal is not
10100 used.
10101 Move aclocal.m4t only if it exists.
10102 Reported by Ezra Peisach.
10104 2001-11-03 Akim Demaille <akim@epita.fr>
10106 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10107 passed on command line, defaulting to ./configure.ac if present.
10108 (&maybe_autoreconf, File::Find): Remove, unused.
10109 (&autoreconf): If autoconf is not used, don't try to trace.
10111 2001-11-02 Akim Demaille <akim@epita.fr>
10113 * configure.ac: Bump to 2.52g.
10115 2001-11-02 Akim Demaille <akim@epita.fr>
10117 Version 2.52f.
10119 2001-11-02 Akim Demaille <akim@epita.fr>
10121 * config/config.guess, config/config.sub, doc/standards.texi:
10122 * config/lispdir.m4: Update from masters.
10123 * configure.ac: Bump to 2.52f.
10125 2001-11-02 Akim Demaille <akim@epita.fr>
10127 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10128 Don't run aclocal when aclocal.m4 is not from aclocal.
10129 From Ezra Peisach.
10130 Don't run libtoolize and gettextize if --install is not given.
10132 2001-11-01 Paul Eggert <eggert@twinsun.com>
10134 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10135 be invoked before _AS_LINENO_PREPARE.
10136 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10137 than character ranges.
10139 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10140 invoking AS_BASENAME. Set the locale variables to 'C' if
10141 possible, as POSIX requires this to get the traditional
10142 behavior.
10143 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10145 2001-10-31 Paul Eggert <eggert@twinsun.com>
10147 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10148 with {}, as that triggers a bug in Bash 2.05.
10150 (_AS_LINENO_PREPARE): Use Sed rather than
10151 Awk. Fix the sed prepass to work even if there are multiple
10152 instances of $LINENO on the same line. Do not substitute for
10153 other variables like $LINENOT. Do not check file dates; such a
10154 check is unreliable on sufficiently fast machines, and removing
10155 the check makes the code simpler and more reliable. Check for
10156 output and chmod failures.
10158 * doc/autoconf.texi (Special Shell Variables): Document
10159 the above.
10161 2001-10-31 Akim Demaille <akim@epita.fr>
10163 * tests/Makefile.am (atconfig): Remove this target, Automake
10164 handles it now.
10166 2001-10-31 Akim Demaille <akim@epita.fr>
10168 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10169 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10170 provided, while it is optional.
10171 * configure.ac: Adjust.
10173 2001-10-26 Paul Eggert <eggert@twinsun.com>
10175 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10176 lib/Autom4te/Struct.pm:
10177 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10178 with 5.005_02.
10180 * doc/autoconf.texi (Special Shell Variables): Document some
10181 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10183 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10184 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10185 eval $LINENO is not portable in practice.
10187 2001-10-24 Akim Demaille <akim@epita.fr>
10189 * lib/Autom4te/General.pm (backname): New.
10191 2001-10-24 Akim Demaille <akim@epita.fr>
10193 * m4/: Remove, merged into...
10194 * config/: here.
10196 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10198 * doc/autoconf.texi (Shellology): Mention the problems with bash
10199 2.05's use of ANSI quoting in its `set' builtin.
10201 2001-10-22 Paul Eggert <eggert@twinsun.com>
10203 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10204 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10205 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10206 POSIX decided to standardize on the int flavor of strerror_r.
10207 Always do char* test, as there's no reason not to.
10208 Assign to a char* var, to catch strerror_r that returns int*.
10210 * doc/autoconf.texi (Particular Functions):
10211 Document the above changes. Also, document the fact that
10212 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10214 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10216 2001-10-20 Akim Demaille <akim@epita.fr>
10218 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
10219 the executable was missing from the log.
10221 2001-10-20 Akim Demaille <akim@epita.fr>
10223 * lib/Autom4te/General.pm (&update_file): If destination is
10224 unchanged, remove the source.
10225 (&up_to_date_p): Don't be verbose, be debug.
10226 * bin/autoreconf.in: No longer support --m4dir.
10227 (&autoreconf): Display the full path of the configure.ac we are
10228 studying.
10229 Trace it only once.
10230 Be sure to honor --force with gettextize.
10231 Always run aclocal.
10232 * doc/autoconf.texi: Adjust.
10234 2001-10-20 Akim Demaille <akim@epita.fr>

10518 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

10684 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
10685 Suggested by Jim Meyering.
10687 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10689 * lib/autoconf/programs.m4: Use extensions listed in
10690 $ac_executable_extensions when looking for programs.
10692 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10694 * lib/autoconf/general.m4: Fix a small Englisho.
10695 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
10696 setting up ac_dir_suffix and ac_top_builddir.
10697 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
10699 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10701 * doc/autoconf.texi (File System Conventions): Clarify the use of
10702 PATH_SEPARATOR.
10703 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
10704 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
10705 be used instead of ':'.
10706 * lib/autotest/general.m4: Replace occurrences of ':' in
10707 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
10709 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10711 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
10712 arguments. Fixed a typo.
10714 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10716 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
10717 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
10719 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10721 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
10722 * bin/autoupdate.in: Ditto.
10723 * bin/autoheader.in: Reworded a few comments.
10724 * bin/autoconf.in: Reworded help text for a few options.
10725 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10726 * bin/autoscan.in, bin/autoupdate.in: Ditto.
10728 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10730 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
10731 already have $file). Set output files to binary mode (helps avoid
10732 CR issues on DOSish systems).
10734 2001-09-19 Akim Demaille <akim@epita.fr>
10736 * lib/autotest/general.m4: Englishoes.
10737 From Tim Van Holder and Alexey Mahotkin.
10739 2001-09-18 Paul Eggert <eggert@twinsun.com>
10741 * doc/autoconf.texi (Common Shell Constructs): New node,
10742 documenting AS_DIRNAME.
10743 (Limitations of Usual Tools): Refer to it when discussing dirname.
10744 Also, update discussion of POSIX standard to reflect latest draft.
10746 * lib/autoconf/c.m4:
10747 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
10749 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10750 Do not pass a first argument with leading '-'
10751 to expr, by parenthesizing initial integers that might be negative.
10753 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
10754 now merely checks whether it is an error to pass an argument
10755 to getpgrp.
10757 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
10758 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
10759 whether it is a (compile-time) error to pass an argument to
10760 getpgrp. This simpler test supports the revised documentation,
10761 and is all that AC_FUNC_GETPGRP's users really need.
10763 2001-09-18 Akim Demaille <akim@epita.fr>
10765 * doc/autoconf.texi (Limitations of Make) <$<>: New.
10767 2001-09-18 Akim Demaille <akim@epita.fr>
10769 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
10770 `{}'.
10771 * lib/autotest/general.m4 (AT_INIT): Adjust.
10773 2001-09-18 Paul Wagland <paul@wagland.net>
10775 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
10776 correctly.
10777 Add test for AS_BASENAME.
10778 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
10779 added test. It now correctly handles /1/2/3/, returning '3' not ''.
10780 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
10781 * tests/base.at: Fixed the expected responses. The old ones were
10782 one line out...
10783 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
10784 the documentation claims it should (and how it behaved in 2.13).
10786 2001-09-18 Akim Demaille <akim@epita.fr>
10788 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
10789 the AC_CONFIG_COMMANDS invocation.
10790 This also solves the name clash problems.
10791 Don't set the package's ID.
10792 * lib/m4sugar/Makefile.am (version.m4): Revamp.
10793 No longer to be shipped.
10794 (version.in): Remove.
10795 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
10796 * lib/autoconf/status.m4: Adjust.
10797 Use `m4_PACKAGE_STRING'.
10798 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
10799 the only optional argument is the name of the test suite.
10800 Expect `package.m4' to define the package signature.
10801 * lib/autom4te.in (Autotest): Add `package.m4?'.
10802 * tests/Makefile.am (package.m4): New.
10803 * tests/suite.at: ifnames is a victim.
10805 2001-09-18 Akim Demaille <akim@epita.fr>
10807 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
10808 AC_LIBSOURCE, AC_CONFIG_FILES.
10809 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
10810 program version string doesn't match the package's.
10811 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
10812 after `(cached)'.
10814 2001-09-17 Paul Eggert <eggert@twinsun.com>
10816 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10817 Allow expression to return any value that can fit into unsigned long
10818 (not int, as before). Check for output errors.
10820 2001-09-17 Bruno Haible <haible@ilog.fr>
10822 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10823 Always include <stdio.h> and <stdlib.h>. Evaluate
10824 the expression in an extra function before these includes. Call
10825 fprintf "%d" only after ensuring the argument is of type 'int'.
10826 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
10828 2001-09-17 Paul Eggert <eggert@twinsun.com>
10830 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
10831 or CFLAGS=-O5. In that case, the linker has a relaxed view of
10832 fatal errors, and AC_CHECK_LIB causes it to include libraries even
10833 when they don't exist.
10835 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
10836 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
10837 need it.
10839 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
10840 version with the version used by fileutils 4.1, except use
10841 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
10842 we don't need it.
10844 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
10846 2001-09-13 Akim Demaille <akim@epita.fr>
10848 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
10849 _first_.
10850 Reported by Gerrit P. Haase.
10852 2001-09-13 Akim Demaille <akim@epita.fr>
10854 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
10855 m4_defn'ing is valid.

10861 Use it.

10870 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
10871 Likewise.

10875 AT_tests_all for consistency.
10876 Set at_victims.
10877 (AT_VICTIMS): Similar to AT_KEYWORDS.
10878 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
10880 2001-09-13 Akim Demaille <akim@epita.fr>
10882 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
10884 2001-09-13 Akim Demaille <akim@epita.fr>
10886 * lib/autotest/general.m4 (AT_INIT): Create and remove
10887 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
10888 test suites can cohabit.
10890 2001-09-13 Akim Demaille <akim@epita.fr>
10892 * tests/mktests.sh: Don't output banners for empty test files.
10894 2001-09-13 Akim Demaille <akim@epita.fr>
10896 Test suites can be run independently of configure.

10942 2001-09-10 Akim Demaille <akim@epita.fr>
10944 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

10977 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
10978 in addition, it introduces useless differences in logs.

10998 2001-09-05 Akim Demaille <akim@epita.fr>

11001 the maintainer is dumb enough to do that...
11003 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11004 excellence in M4 quotation: consider `__file__' is active.
11006 And BTW, when invoking m4, pass the --include in the right order:

11032 2001-09-05 Akim Demaille <akim@epita.fr>

11037 New, extracted from main.
11038 Use IO::File wherever possible.
11039 (input.m4): Be constant, use -I instead of hard coding $tmp.

11041 Don't invoke `_au_disable', since ac was not loaded, but just
11042 `unm4.m4'.
11044 2001-08-31 Akim Demaille <akim@epita.fr>
11046 Version 2.52d.

11069 2001-08-31 Akim Demaille <akim@epita.fr>
11071 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11072 (testsuite Scripts): There is no such thing as `atconfig.in'.

11075 2001-08-31 Akim Demaille <akim@epita.fr>
11077 * lib/Autom4te/General.pm (&find_file): Browse the includes in the

11083 to m4sugar was lacking!
11085 2001-08-31 Akim Demaille <akim@epita.fr>

11088 autom4te_perllibdir.
11090 2001-08-31 Akim Demaille <akim@epita.fr>
11092 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11093 debug scripts, in particular passing explicitly listed tests to
11094 run is stupid.
11096 2001-08-31 Akim Demaille <akim@epita.fr>
11098 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11099 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11100 Use directly autom4te, not autoconf.

11125 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
11126 (autoheader): Pass --force since the test suite goes too fast for
11127 the time stamps.
11128 Adjust to the new autoheader messages.

11140 * lib/Autom4te/General.pm (&find_file, &update_file): New.
11141 * bin/autoupdate.in, bin/autoheader.in: Adjust.
11142 Drop AC_MACRODIR dead for real.
11143 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11144 `autoheader: `config.hin' is created'.
11145 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11147 2001-08-31 Akim Demaille <akim@epita.fr>
11149 * bin/autoheader.in: Rewrite in Perl.
11150 * tests/autoheader: Adjust.
11152 2001-08-31 Akim Demaille <akim@epita.fr>
11154 * bin/autoconf.in (--include, -I): New option.
11155 Map --localdir, --autoconf-dir onto it.
11156 Forward autom4te's options instead of interpreting them.
11157 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11158 There is no such envvar since the inception of autom4te.cfg.
11159 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11160 * bin/autoupdate.in: Adjust, and perform more control.
11161 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
11162 * tests/autoconf: Dittowise.
11164 2001-08-31 Akim Demaille <akim@epita.fr>
11166 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
11167 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11168 optionally `FILE'.
11169 Use -e, not -f, since /dev/null for instance is OK.
11170 (&parse_args): Adjust.
11171 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11173 2001-08-31 Akim Demaille <akim@epita.fr>
11175 * configure.ac: Also find tested executables in bin.
11176 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11177 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11178 installed peer executables, only PATH is allowed to resolve it.
11179 Pass `autoconf_dir' via options, not via invisible envvars.
11180 * lib/Autom4te/General.pm (&find_peer): Remove.
11181 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11182 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11183 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11184 find the executables for it.
11185 * tests/Makefile.am: Major cleanup. Too lazy to document...
11186 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11187 We only need PERL.
11188 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11189 indeed related to running the test suite, while passing
11190 --autoconf-dir and others is related to running non installed
11191 Autoconf executables. So don't do that, leave it to...
11192 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11193 * tests/autoscan: New.
11194 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11195 refer to library files: rely on --language.
11197 2001-08-29 Akim Demaille <akim@epita.fr>
11199 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
11200 s/--set/--language/.
11202 2001-08-29 Akim Demaille <akim@epita.fr>
11204 * doc/autoconf.texi: Strip the @nodes.
11205 Suggested by Paul Eggert.
11206 (Initializing configure): Typo.
11208 2001-08-29 Akim Demaille <akim@epita.fr>
11210 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11211 Suggested by Paul Eggert.
11213 2001-08-29 Akim Demaille <akim@epita.fr>
11215 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11216 download in a tmp dir.
11218 2001-08-29 Akim Demaille <akim@epita.fr>
11220 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
11221 case insensitive OSes out there :(
11222 From Tim Van Holder.
11224 2001-08-29 Akim Demaille <akim@epita.fr>
11226 * lib/autom4te.in: New.
11227 * lib/Makefile.am (edit, autom4te.cfg): New.
11228 * bin/autom4te.in (BEGIN): Simplify.
11229 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
11230 (&load_configuration): New. Use it.
11231 (&parse_args): Support --mode, --set, and --melt.
11232 * bin/autoconf.in: Simplify and adjust.
11233 * tests/Makefile.am (AUTOMAKE): Use --set.
11234 * tests/atlocal.in: Adjust.
11235 * BUGS: distcheck and check are weak.
11237 2001-08-29 Akim Demaille <akim@epita.fr>
11239 * lib/autotest/general.m4: Use
11240 foo=`(command) 2>/dev/null`
11241 not
11242 foo=`command` 2>/dev/null
11243 (at-devnull): Rename as...
11244 (AT-devnull): this.
11245 (--clean): Remove AT-* files too.
11246 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
11247 Reported by Nicolas Joly.
11249 2001-08-28 Akim Demaille <akim@epita.fr>
11251 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
11252 quotes inside single quotes.
11253 Reported by Nicolas Joly.
11255 2001-08-28 Kevin Ryde <user42@zip.com.au>
11257 * doc/autoconf.texi (Function Portability): Mention C right shifts.
11259 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
11261 * lib/autotest/general.m4: Reword some messages.
11262 (AT_INIT): Check for the `times' builtin before using it.
11263 Support test ranges as arguments to the testsuite.
11264 Have -e imply -d as the help text suggested.
11266 2001-08-27 Akim Demaille <akim@epita.fr>
11268 * Makefile.maint: Formatting changes.
11269 (do-po-update, po-update, cvs-update, update): New targets.
11270 (AMTAR): Remove.
11272 2001-08-27 Akim Demaille <akim@epita.fr>
11274 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

11281 * lib/autotest/general.m4 (AT_INIT): Log the command line.
11282 Support `VAR=VAL' as arguments.
11283 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
11284 may be set via the command line.
11286 2001-08-27 Akim Demaille <akim@epita.fr>
11288 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
11289 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
11290 first the build dirs, then the src dirs.

11293 2001-08-27 Akim Demaille <akim@epita.fr>
11295 * lib/autotest/general.m4 (AT_INIT): Output the definition of
11296 at_data_files earlier.
11297 (--clean, -c): New option.
11298 * tests/Makefile.am: Use this option.
11300 2001-08-27 Akim Demaille <akim@epita.fr>
11302 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
11303 `ac_top_builddir' to mimic Automake's vocabulary, which much more
11304 readable.
11305 Adjust callers.
11306 * doc/autoconf.texi (Configuration Actions): Document the vars
11307 available in commands.
11308 Emphasize the risks of collisions in init-cmds.
11310 2001-08-27 Akim Demaille <akim@epita.fr>
11312 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
11313 (Initializing configure): this new node.
11315 2001-08-27 Akim Demaille <akim@epita.fr>

11338 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
11339 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
11340 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
11341 -> ac_dir).
11342 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
11343 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
11345 2001-08-27 Akim Demaille <akim@epita.fr>

11370 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
11371 (AMTAR): Help automake define it.
11372 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
11373 needed, 1.5 can have a macro and a target with the same name.
11374 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
11375 * m4/strip.m4: New.

11388 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
11389 Adjust callers.
11390 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
11391 the name of the directory they're in, instead of the filename,
11392 since version.m4 is now in m4sugar, but m4_acversion must not be
11393 classified as an Autoconf macro.
11394 ($input_m4): Don't qualify the path to m4sugar.
11395 Rather, pass autoconf_dir to m4.
11396 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
11397 * tests/suite.at: Require 2.52c.
11399 2001-08-27 Akim Demaille <akim@epita.fr>

11411 of config.log on traps.
11412 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
11413 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
11414 for config.status'.
11415 Open the log as soon as possible.
11416 Use the same log introduction as configure's.
11418 2001-08-22 Paul Eggert <eggert@twinsun.com>
11420 * doc/autoconf.texi (Indices): New node.
11421 Move indices out of the top level menu and into this submenu.
11423 2001-08-22 Akim Demaille <akim@epita.fr>
11425 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11426 AC_TRY_COMMAND.
11427 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.
11429 2001-08-22 Akim Demaille <akim@epita.fr>
11431 * lib/autoconf/general.m4 (AC_SHELL_PATH_WALK, AC_CHECK_PROG)

11436 (AC_PROG_RANLIB, AC_PROG_YACC, AC_PROG_LEX, _AC_DECL_YYTEXT)
11437 (AC_PROG_INSTALL, AC_PROG_LN_S, AC_RSH): Move to...
11438 * lib/autoconf/programs.m4: here.
11439 (_AC_DECL_YYTEXT): Rename as...

11468 * configure.ac (AT_CONFIG): Fix the path.
11469 * m4/atconfig.m4 (AT_CONFIG): Don't use EOF but ATEOF so that 2.52
11470 can be used.

11474 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
11475 program with AC_LANG_PROGRAM before feeding it to
11476 AC_COMPILE_IFELSE. Cleanup grep usage.
11478 2001-08-20 Akim Demaille <akim@epita.fr>
11480 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
11481 * NEWS, README, README-alpha, TODO, tests/README: This package is
11482 `Autoconf', not `autoconf' (the executable).
11484 2001-08-20 Akim Demaille <akim@epita.fr>
11486 Info readers seem to need `Index' in the index node title :(
11488 * doc/autoconf.texi: Reverse the 2001-08-15 change which
11489 simplified index node names.
11491 2001-08-20 Akim Demaille <akim@epita.fr>
11493 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
11494 arguments are not literals.
11495 * doc/autoconf.texi (Input) <AC_INIT>: Arguments must be literals.
11496 Specify the output variables, and macros defined.
11498 2001-08-20 Akim Demaille <akim@epita.fr>
11500 * doc/autoconf.texi (Examining Declarations) <AC_TRY_CPP>:
11501 (Examining Syntax) <AC_TRY_COMPILE>
11502 (Examining Libraries) <AC_TRY_LINK>
11503 (Test Programs) <AC_TRY_RUN>: These macros double quote some of
11504 their arguments.
11505 Reported by Werner Lemberg.
11507 2001-08-20 Akim Demaille <akim@epita.fr>

11524 * lib/autoconf/general.m4 (_AC_OUTPUT_COMMANDS): Say what you do.
11525 * m4/atconfig.m4 (AT_CONFIG): $1 is now the directory where the
11526 test suite lives.
11527 Create `atconfig' automagically.
11528 Configure atlocal.in if present.
11529 * tests/atconfig.in: Remove.
11530 * tests/atlocal.in: New.

11533 2001-08-20 Akim Demaille <akim@epita.fr>
11535 Huh!?!?! There are still some user EOF tags used, which prevents
11536 their use in AC_CONFIG_COMMANDS for instance...
11538 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
11539 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
11540 `_CSEOF', or `_ATEOF', as appropriate.
11541 * lib/m4sugar/Makefile.am, lib/autoconf/Makefile.am,
11542 * lib/autotest/Makefile.am (check-local): Enforce this constraint.

11552 Autotest invokes M4sh's initialization.
11554 * lib/autotest/general.m4: Adjust the diversion names.
11555 (AT_INIT): Run AS_INIT.

11620 * doc/autoconf.texi: Work around Texinfo buglets.

11675 (cvs-dist): depends upon it.
11677 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
11679 * tests/Makefile.am: Use a clean-local rule to remove
11680 autom4te.cache (it's a directory, not a file.
11681 * Makefile.am: Ditto (but maintainer-clean-local).
11683 2001-08-15 Akim Demaille <akim@epita.fr>
11685 * bin/autom4te.in (@m4_warning): New.
11686 (&handle_m4): Use it.
11687 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
11688 warnings are issued at each run.
11689 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
11690 is in the src tree.
11692 2001-08-15 Akim Demaille <akim@epita.fr>
11694 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
11695 don't waste time running `autoupdate --version' works.
11696 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
11698 2001-08-13 Akim Demaille <akim@epita.fr>

11757 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11759 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
11760 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
11761 * doc/autoconf.texi (C Compiler Characteristics): Update
11762 documentation for AC_C_BIGENDIAN.
11764 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11766 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
11767 magic values from an object file when cross-compiling.
11768 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
11770 2001-08-10 Akim Demaille <akim@epita.fr>
11772 * bin/autom4te.in (&handle_output): Don't use `grep' with side
11773 effects.
11774 Suggested by Russ Allbery.
11776 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
11778 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
11779 current $prefix to the sub-configures.
11781 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
11783 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
11784 extension (needed on BeOS). Reported by Guido van Rossum.
11786 2001-08-09 Akim Demaille <akim@epita.fr>
11788 * bin/autom4te.in ($icache): Load it only if older than autom4te.
11790 2001-08-07 Akim Demaille <akim@epita.fr>
11792 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
11793 removed.
11794 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
11795 No need to remove the files before and after the each test, before
11796 each test and at the end of the suite is enough.
11797 Display only the children `times', not the shell's.
11798 If the test failed or was skipped, at-times is not available.
11800 2001-08-07 Akim Demaille <akim@epita.fr>
11802 Always produce testsuite.log, including when there are no
11803 failures. This helps getting information on skipped tests, and
11804 duration of the tests. Err, implement the latter btw.
11806 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
11807 Dump information on the first run of each test.
11808 (AT_CLEANUP): Create `at-times' containing the duration of the
11809 test group.
11811 2001-08-07 Akim Demaille <akim@epita.fr>
11813 The use of `dumpstat' revealed that `len' was used although it
11814 should not. m4_text_wrap was using it, but in the Autoconf world
11815 where it is legal. Hence (i) test M4sh in its own world, not
11816 Autoconf's, and (ii), ahem, fix the bug :)
11818 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
11819 does not like `' instead of [].
11820 (AT_INIT): Forbid `^_?AT_'.
11821 And don't output such tokens.
11822 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
11823 `script.as', and `autom4te.cache'.
11824 Remove `empty' and `macro' which are no longer used.
11825 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
11826 * tests/m4sugar.at: Use it.
11827 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
11829 2001-08-07 Akim Demaille <akim@epita.fr>
11831 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
11833 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
11835 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
11837 2001-08-04 Akim Demaille <akim@epita.fr>
11839 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
11840 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
11841 AC_TRY_LINK.
11842 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
11843 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
11844 (AC_F77_MAIN): Likewise.
11846 2001-08-04 Akim Demaille <akim@epita.fr>
11848 Don't rely on M4sugar outputting the patterns in files, since we
11849 might process the output _without_ running m4, hence without these
11850 files.
11852 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
11853 * bin/autom4te.in (@Request::includes): Remove, unused.
11854 (@Request::source): Rename as...
11855 (@Request::input): this.
11856 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
11857 (&handle_output): Fetch the patterns from the traces.
11858 `$forbidden' and `$allowed' are constant: use m//o.
11859 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
11860 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
11862 2001-08-04 Akim Demaille <akim@epita.fr>
11864 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
11865 autoconf', i.e., in addition to caching traces, cache the output.
11867 * bin/autom4te.in (Request::cache): Rename as...
11868 (Request::id): this.
11869 ($cache, $icache, $tcache, $ocache): New.
11870 (&handle_m4): Save M4 output in the cache instead of $tmp.
11871 (&handle_output): Adjust.
11872 (&up_to_date_p): Check that the output cache is up to date too.
11873 (top level): Run `&handle_m4' iff force or the cache is invalid.
11874 Run `&handle_output' if the output cache is more recent.
11876 2001-08-04 Akim Demaille <akim@epita.fr>
11878 * bin/autom4te.in ($force): New.
11879 (&parse_args, &print_usage): -f, --force is a new option.
11880 (&handle_output): CPP directives might have spaces after `#'.
11881 (&parse_args): The first file only can be frozen.
11883 2001-08-04 Akim Demaille <akim@epita.fr>
11885 Don't let autom4te compute the `include' traces several times:
11886 first check that the trace cache file is up to date, and then
11887 compare its timestamp with that of the output.
11889 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
11890 the preamble. Don't require 5.005 as Autom4te::General does it,
11891 and better yet (use `use', not `require'!).
11892 * lib/Autom4te/Struct.pm: Rename the last occurrences of
11893 Class::Struct as Autom4te::Struct.
11894 * lib/Autom4te/General.pm (File::stat): Use it.
11895 (&mtime): New, export it.
11896 * bin/autom4te.in: Use it.
11897 Declare `$req' is invalid if it is outdated.
11898 Don't declare it valid before saving it if something went wrong.
11900 2001-08-04 Akim Demaille <akim@epita.fr>
11902 Autom4te shall not encode Autoconf data, and preselecting traces
11903 must be proposed to the users.
11905 * bin/autom4te.in (@required_trace): Remove.
11906 (@preselect): New.
11907 (&parse_args, &print_usage): -p, --preselect is a new option.
11908 (&up_to_date_p): Adjust.
11909 * bin/autoconf.in: Preselect some Autoconf macros.
11911 2001-08-04 Akim Demaille <akim@epita.fr>
11913 * tests/tools.at (autoconf --trace: user macros): Check traces on
11914 macros invoked without arguments, and macros invoked with multiple
11915 lines arguments.
11917 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
11919 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
11920 arguments.
11922 2001-08-03 Akim Demaille <akim@epita.fr>
11924 * bin/autoconf.in ($@): Work around the usual sh bug.
11925 From Nicolas Joly.
11927 2001-08-03 Akim Demaille <akim@epita.fr>
11929 Clean up the handling of the M4 builtins tracing exception.
11931 * bin/autom4te.in (Request::request): Don't complete M4 builtins
11932 trace requests.

11934 (@m4_builtin): this.
11935 (%m4_builtin_alternate_name): New.
11936 (&parse_args): Complete the trace requests with alternate names.
11937 (&handle_traces): Hence no longer do it here.
11938 (&trace_requests): Remove, unused.
11940 2001-08-03 Akim Demaille <akim@epita.fr>
11942 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
11943 m4_if, and m4_wrap.
11945 2001-08-03 Akim Demaille <akim@epita.fr>
11947 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
11948 (m4_divert_pop): Dump the whole diversion stack when a diversion
11949 mismatch happens.
11950 * bin/autom4te.in (&handle_output): Remember of the first
11951 occurrence of a possibly undefined macro, not the last.
11952 Complain about the possibly undefined macros in the same order as
11953 the appear in the output.
11954 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
11955 * tests/tools.at (autoconf: forbidden tokens, basic)
11956 (autoconf: forbidden tokens, exceptions): No longer sort
11957 autoconf's stderr, as it is now deterministic.
11958 Check that `dnl' is caught.
11960 2001-08-01 Akim Demaille <akim@epita.fr>
11962 * configure.ac: Bump to 2.52c.

11977 `die'.
11978 (&END): New.
11979 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
11980 `END', as `Autom4te::General::END' will be triggered.
11981 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
11982 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

12374 compiler, not the preprocessor.
12375 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): No longer use

12381 2001-07-03 Akim Demaille <akim@epita.fr>

12410 * aclang.m4 (AC_F77_DUMMY_MAIN): New macro to detect whether a
12411 dummy alternate main is required even if the user provides her own
12412 'main'.
12413 (AC_F77_MAIN): New macro to detect whether it is possible to
12414 provide an alternate 'main' function name, using the 'main' from
12415 the Fortran libraries.
12416 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
12417 cross-language link tests can be performed successfully.
12418 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
12419 after $LIBS, for consistency; this should be the general rule since
12420 the user may want to link to Fortran libraries that require $FLIBS.
12421 * doc/autoconf.texi: Document AC_F77_DUMMY_MAIN and AC_F77_MAIN.
12423 2001-06-29 Pavel Roskin <proski@gnu.org>
12425 * atgeneral.m4 (AT_CHECK): Add a newline to the end of
12426 at-stdout and at-stderr instead of removing the newline
12427 from the echo output, which is not guaranteed to work.
12429 2001-06-28 Jens Petersen <petersen@redhat.com>
12431 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to

12463 explicit macros is mapped to the default macro.
12464 (&print_unique): Remove, inlined in...
12465 (&output_kind): here.
12466 (File::Basename): Use it.

12475 Suggested by Mo DeJong.
12477 2001-06-24 Akim Demaille <akim@epita.fr>

12488 2001-06-23 Akim Demaille <akim@epita.fr>
12490 * tests/torture.at (AC_ARG_VAR): Make it a single test instead of
12491 three as failures are unlikely, and speed matters.
