3 * BUGS: Remove mention of VPATH problem, since it's now documented
4 not to be a bug in the Autoconf build procedure itself, but rather
5 a problem with the proprietary `make' programs.
7 * doc/autoconf.texi (Build Directories): Add a cross reference
8 to VPATH and Make.
10 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
11 * doc/standards.texi: Sync from gnulib.
13 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
14 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
15 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
16 generated automatically.
18 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
20 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
21 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
22 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
24 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
26 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
27 `CEOF$ac_eof' special marker, the awk script cannot contain a
28 line matching `^CEOF', so this is not needed any more.
29 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
30 special marker in the test.
32 2006-12-06 Stepan Kasal <kasal@ucw.cz>
34 * tests/tools.at (autom4te preselections): Use `find -newer';
35 remove one of the sleeps.
37 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
38 more readable, using ...
39 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
41 * doc/autoconf.texi (autoheader Invocation): Do not double-
42 quote the parameter of `AH_BOTTOM' in the example.
44 2006-12-05 Stepan Kasal <kasal@ucw.cz>
46 * doc/autoconf.texi (Configuration Headers): Remove the
47 example with multiple input files.
48 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
49 multiple input files.
51 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
53 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
54 creating the awk substitution script, handle one input line at a
55 time, so that the maximum length of a substituted (multi-line)
56 value is not limited by the size of the sed pattern space.
57 The trade-off is a slightly repetitive sed script.
58 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
59 can only have up to 7 characters, due to Solaris 10 /bin/sed.
60 * tests/torture.at (Substitute a 2000-byte string): Increase the
61 test with several long lines, they should not be caught by sed
62 limits any more.
64 * tests/tools.at (autom4te preselections): New test, to flag
65 entries missing from autom4te.cfg.
66 Report by David Byron <dbyron@hheld.com>.
68 * tests/torture.at (Substitute a 2000-byte string): Actually use
69 AC_PROG_AWK, so the last change works as intended.
70 (Substitute and define special characters): Likewise.
71 (Substitute a newline): Likewise.
73 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
74 instead of `awk' consistently.
75 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
76 * tests/torture.at (Torturing config.status): Test both the
77 result of AC_PROG_AWK and plain awk.
78 (Substitute a 2000-byte string): Likewise.
79 (Substitute and define special characters): Likewise.
80 (Substitute a newline): Likewise.
82 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
84 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
85 can be assigned to a function pointer. Problem reported by
86 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
87 part of a patch by Ralf Wildenhues in that same bug report.
89 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
91 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
92 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
94 2006-12-01 Eric Blake <ebb9@byu.net>
96 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
97 cross-compiling from cygwin to mingw.
98 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
99 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
100 to lib/autoconf/c.m4.
102 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
104 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
105 string for more reliable failure. Wrap the entire test that
106 causes the broken Solaris printf to dump core, in a subshell,
107 so the segmentation fault message is reliably suppressed.
108 Fix shell expansion errors by using /usr/ucb/echo always;
109 avoid an error on systems without it by another subshell.
110 Avoid m4 expansion of `$1'. Set the zeroth argument of the
111 subshell-$as_echo to `as_echo', for better error message.
113 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
115 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
116 `BASH_SOURCE' contain a newline, set them to empty, as they may
117 not be unset.
119 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
121 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
122 years and is too hard to maintain now. The last straw was
123 reported by Jerker Baeck in
124 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
125 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
126 * doc/autoconf.texi (Particular Functions): Move
127 AC_FUNC_SETVBUF_REVERSED from here...
128 (Obsolete Macros): ... to here. Say that it does nothing now.
129 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
130 Turn into (almost) a no-op.
132 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
133 (AC_C_VOLATILE):
134 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
135 These macros are obsolescent and new applications shouldn't need them.
136 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
137 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
138 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
139 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
140 (AC_FUNC_VPRINTF): Likewise.
141 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
142 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
143 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
145 * doc/autoconf.texi (Setting Output Variables): Mention that
146 @VAR1@VAR2 has unspecified behavior. Problem reported by
147 Ralf Wildenhues.
148 * NEWS: Mention this.
150 * Makefile.am: Put only a single '#' into the copyright notice,
151 so that it's also present in the output file. Standardize wording
152 in makefile copyright notices to match GNU coding standards.
153 * bin/Makefile.am: Likewise.
154 * doc/Makefile.am: Likewise.
155 * lib/Makefile.am: Likewise.
156 * lib/freeze.mk: Likewise.
157 * lib/autoconf/Makefile.am: Likewise.
158 * lib/autoscan/Makefile.am: Likewise.
159 * lib/autotest/Makefile.am: Likewise.
160 * lib/m4sugar/Makefile.am: Likewise.
161 * man/Makefile.am: Likewise.
162 * tests/Makefile.am: Likewise.
163 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
164 one-line file.
166 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
168 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
169 in the sed script that mangles the awk script: delete up to the
170 first exclamation mark only.
171 * tests/torture.at (Substitute and define special characters):
172 Test '!' too.
174 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
176 Rewrite config files generation: avoid quadratic growth in
177 the number of substituted variables by using awk instead of sed
178 for the bulk of the substitutions.
179 * NEWS: Mention this.
180 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
181 forbidden in the output (and thus input) file.
182 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
183 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
184 generate just one large awk script for substitutions,
185 eliminating much of the earlier complexity, while adding some
186 new complexity. Only expand the substitution templates at
187 configure time, for smaller configure script size. If
188 _AC_SUBST_FILES are used, test 'awk' for working getline support
189 at config.status time. If absent, interpolate through the
190 shell. The awk script was written with much help
191 from Paolo Bonzini and Paul Eggert.
192 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
193 (_AC_SED_FRAG_NUM): Likewise.
194 (_AC_SUBST_CMDS): Renamed from...
195 (_AC_SED_CMDS): ...this.
196 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
197 * tests/torture.at (Substitute a 2000-byte string): Also
198 substitute a line with 1000 words, and a variable with several
199 long lines.
200 (Substitute and define special characters): Test awk special
201 characters, and put substitution input strings `@foo@' in the
202 output, to test that no recursion happens; test several other
203 combinations from Paolo Bonzini.
205 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
207 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
208 that replaced echo with AS_ECHO where this wasn't necessary.
209 Problem reportd by Ralf Wildenhues.
210 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
211 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
212 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
214 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
216 * lib/freeze.mk (GREP): Removed, no need to initialize this.
218 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
220 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
221 that traditional Awk lacks 3-arg "split". It has it.
222 Mention that FS must be a single character, and a few other
223 99-byte limits of traditional Awk.
224 Mention that if (i in a) doesn't work with traditional Awk.
226 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
228 * tests/autotest.at (BSx641-newline in command):
229 (BS-BS-newline in command, BSx640-newline in command):
230 (Newline-CODE-BS-newline in command):
231 (Single-quote-BS-newline in command):
232 (Single-quote-newline-BS-newline in command):
233 Use printf '%s\n' instead of echo, for portability to hosts
234 where echo interprets backslashes. This will break on hosts
235 that lack printf, but for now let's assume all such hosts
236 are dead (if not, we should get reports of test failures).
238 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
240 'echo' has some portability problems, when given a first argument
241 with a leading '-', or when given any argument containing '\'.
242 Avoid using 'echo' in these cases.
243 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
244 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
245 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
246 * lib/autotest/general.m4 (AT_INIT): Likewise.
247 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
248 argument might be unportable.
249 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
250 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
251 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
252 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
253 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
254 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
255 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
256 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
257 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
258 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
259 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
260 (AC_PROG_MAKE_SET): Likewise.
261 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
262 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
263 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
264 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
265 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
266 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
267 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
268 * bin/autoconf.as: Redo verbose flag implementation, as the old
269 scheme wouldn't work with AS_ECHO.
270 * lib/autotest/general.m4 (AT_INIT): Likewise.
271 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
272 Don't use ECHO_T, since ECHO_N is now reliable.
273 * lib/autotest/general.m4 (AT_INIT): Likewise.
274 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
275 rather than using a here-document to put the script into a file.
276 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
277 use AS_ECHO.
278 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
279 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
280 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
281 bug, but we might as well stop using ECHO_N and ECHO_C internally.
282 * lib/autotest/general.m4 (AT_SETUP): Likewise.
283 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
284 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
285 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
286 operand, as AS_ECHO requires. Avoid double file name expansion.
287 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
288 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
289 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
290 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
291 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
292 Double-quote strings that would otherwise contain M4 comments.
293 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
295 * configure.ac (AC_INIT): Bump to 2.61a.
296 * NEWS: Likewise.
298 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
300 Version 2.61.
302 * configure.ac (AC_INIT): Bump to 2.61.
303 * NEWS: Likewise.
305 * tests/autotest.at (Macro with backslash in a test title):
306 Comment out for now, as this tests neither fails nor passes
307 reliably. Problem reported by Ralf Wildenhues.
309 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
311 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
312 in previous change, which caused test failures.
314 2006-11-16 Stepan Kasal <kasal@ucw.cz>
316 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
317 code for --enable, --disable, --with, and --without to...
318 (_AC_INIT_PARSE_ENABLE): ... a new macro.
319 * doc/autoconf.texi (Package Options):
320 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
322 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
324 Import these changes from config via gnulib:

365 no further ado.
367 2006-11-05 Karl Berry <karl@gnu.org>
369 * doc/texinfo.tex (Image Syntax): don't mention GIF any more.

381 first argument may also contain dots.
383 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
385 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
386 benefit of platforms like Solaris+GCC where it is common to have a
387 non-working g++ installation.
389 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

394 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
395 ./micro-suite.
397 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
399 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
400 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
401 Imported from a similar patch to gnulib by Bruno Haible.
403 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
405 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
406 * doc/autoconf.texi (C Compiler): Document them.
407 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
408 New macros, taken from gnulib.
410 2006-11-07 Paul Eggert <eggert@cs.ucla.edu>
412 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Detect bug in
413 Tandem NonStop Kernel (OSS) cc -O circa 2004, reported by
414 Matthew Woehlke.
416 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
418 * tests/torture.at (Configuring subdirectories): Do not skip
419 Automake 1.10 nor future Automake 11.1 (sic).
421 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
422 and Stepan Kasal <kasal@ucw.cz>
424 Handle special characters in test case titles correctly.
425 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
426 properly.
427 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
428 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
429 argument. Extend to check titles printed by ./micro-suite and
430 ./micro-suite -l and the title in micro-suite.log.
431 (Backquote in a test title,
432 Single-quote in a test title,
433 Double-quote in a test title): Don't expect failure anymore.
434 (Backslash in a test title): Put a non-whitespace character after the
435 backslash so that Bourne shells might actually see it as an escape
436 sequence.
437 (Brackets in a test title,
438 Pound in a test title,
439 Comma in a test title,
440 Quoted Macro in a test title,
441 Macro in a test title,
442 Macro with single-quote in a test title): New tests.
443 (Macro with backquote in a test title,
444 Macro with double-quote in a test title,
445 Macro with backslash in a test title): New tests expected to fail.
446 * tests/torture.at (#define header templates): M4-quote this title in
447 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
448 The visible effect was a stray [] in the testsuite output.
450 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
452 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
453 `trap ... 0' inside a function, for AIX sh.
455 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
457 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
458 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
459 5363) simply issues a warning when dividing by zero at compile
460 time. Problem reported by Elias Pipping.
462 2006-10-26 Eric Blake <ebb9@byu.net>

465 * doc/autoconf.texi (Evaluation Macros): Improve the example to
466 show effect on macros that expand with commas.
467 Reported by Joel E. Denny.

480 `--force' always rewrites the output file.
482 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
484 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm
485 needs operands on NetBSD 2.0.2. Problem reported by Bruno Haible.
487 2006-10-24 Stepan Kasal <kasal@ucw.cz>
489 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
491 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
493 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
494 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
495 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
496 reported by Nelson H. F. Beebe for Coreutils 6.4.
498 * tests/tools.at (autoconf --trace: user macros): Remove test
499 for tracing multiline macros, since m4 1.4.7a uses a different
500 way to number lines. Problem reported by Ralf Wildenhues.
502 2006-10-24 Stepan Kasal <kasal@ucw.cz>
504 * bin/autom4te.in (handle_m4): Do not redirect stdin to
505 /dev/null since the heuristics for interactive behaviour was
506 fixed in CVS m4.
508 * bin/autom4te.in: With --force, always refresh the output
509 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

524 * build-aux/texinfo.tex: automake 1.10
526 * NEWS: Remove AC_CACHE_CHECK_INT.
527 * doc/autoconf.texi (Caching Results): Likewise.
528 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
529 AC_CACHE_CHECK_INT, since it's no longer public.
530 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
531 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
533 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
535 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
537 2006-10-19 Eric Blake <ebb9@byu.net>
539 * lib/m4sugar/m4sugar.m4 (m4_mkstemp): New macro.
540 (m4_maketemp): Avoid warnings with M4 1.9a.

542 m4_mkstemp.

551 Standards.

559 2006-10-14 Stepan Kasal <kasal@ucw.cz>
561 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
562 looking for special shell characters.
563 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
564 macro defined by AS_VAR_PUSHDEF before passing it as a
565 parameter.
566 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
567 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

576 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
578 (Imported from Automake.)
579 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
580 which incorrectly sets the mode of an existing destination
581 directory. In some cases the unpatched install-sh could do the
582 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
583 system. We hope this is rare in practice, but it's clearly worth
584 fixing. Problem reported by Alex Unleashed in
585 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
586 Also, don't bother to check for -m bugs unless we're using -m;
587 suggested by Stepan Kasal.
589 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
591 Import this change from Automake:
593 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
594 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
595 is enabled by default with gnu and gnits strictness.
596 Report from Bruno Haible.
598 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
599 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
600 gnu and gnits modes.
602 Import this change from Config:
604 2006-09-20 Ben Elliston <bje@gnu.org>
605 * build-aux/config.sub (score, score-*): New.
607 Import this change from Gnulib:
609 2006-09-16 Karl Berry <karl@gnu.org>
610 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
611 to avoid sectioning errors.
613 Import these changes from Texinfo:
615 2006-10-04 Karl Berry <karl@gnu.org>
616 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
617 (\quoteexpand): rename to \rquoteexpand.
618 (\codequoteleft): new def, to look for @set codequotebacktick.
619 (\lquoteexpand, \quoteexpand): new defs.
620 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
621 (\code): must use new \...Char values, since now ` is active.
623 2006-08-26 Karl Berry <karl@gnu.org>
624 * build-aux/texinfo.tex (\textdegree): New command.
626 2006-08-12 Karl Berry <karl@gnu.org>
627 * build-aux/texinfo.tex (error \box0): smaller font.

631 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
633 2006-10-13 Stepan Kasal <kasal@ucw.cz>
635 * doc/autoconf.texi (Autoheader Macros): Warn that the text
636 added to the template can get mangled.
638 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
640 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
641 include the default headers, and redefine obstack_chunk_alloc
642 and obstack_chunk_free. Fixes false failure with glibc.
644 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
646 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
647 for backward compatibility with Libtool 1.5.22. Problem reported
648 by Ralf Wildenhues.
650 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
652 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
653 AC_PROG_CC.
654 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
656 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
658 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
659 the NonStop platform.
660 * doc/autoconf.texi (Posix Variants): Likewise.
661 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
663 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
664 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
665 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
666 Use a better substitute, by inspecting the output of "ls"
667 rather than just using ":".
668 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
669 rather than AS_EXECUTABLE_P, since we needn't worry about
670 non-regular files here.
672 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
673 due to configuration hassles with this. See Tonya Underwood's report
674 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
675 * doc/autoconf.texi (Special Shell Variables): Likewise.
677 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
678 Stepan Kasal <kasal@ucw.cz>
680 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
681 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
683 2006-10-11 Stepan Kasal <kasal@ucw.cz>
685 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
686 initialization which is not inherited through the environment
687 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
688 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
690 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
692 * doc/autoconf.texi (Limitations of Usual Tools): Describe
693 problems with mkdir -p -m.
695 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
697 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
698 comment about ac_cpp_err; it was incorrect, and anyway
699 ac_cpp_err is being removed below.
700 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
701 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
702 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
703 nobody uses it.
704 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
705 with werror_flag and conftest.err and so forth. This is more
706 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
707 and anyway the user shouldn't normally want to see this gorp logged.
708 Problem reported by Ralf Wildenhues.
709 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
710 empty, not 'no', since the rest of the code uses 'test -z'.
712 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
714 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
715 Use a single call to AC_DO_TOKENS rather than multiple, for
716 efficiency.
717 (_AC_LINK_IFELSE): Test that resulting file is executable.
718 Problem reported by mwoehlke in
719 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
721 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
722 than creating a file to use with test -x; this is much faster.
724 2006-10-02 Bruno Haible <bruno@clisp.org>
726 * lib/autom4te.in (Automake-preselections): Add
727 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
729 2006-09-27 Stepan Kasal <kasal@ucw.cz>
731 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
732 standard error, `experr' should be used, not `expout'.
734 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
736 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
737 fseeko testing program twice; just use the earlier result.
738 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
739 Set cache var to 'unknown' (not 'no') if leaving the macro unset
740 still doesn't let the program compile.
741 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
742 failed.
744 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
745 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
746 include it, without including anything else.
747 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
748 expressions.
749 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
751 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
753 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
754 `error.h', and include it, for a `error_at_line' prototype.
755 Use a nonempty format string in the link test.
756 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
757 for a declaration of wait3.
759 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
761 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
762 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
763 can apply to constants too, and that it checks for macro defns.
764 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
765 and simply cast the identifier to void. This handles structure
766 values. Problem reported by Ralf Wildenhues.
767 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
769 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
771 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
772 structure, and function symbols.
774 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
776 * tests/semantics.at (AC_CHECK_MEMBERS): Also test with a struct
777 member.

789 warnings (uninitialized value).
790 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
791 present.
792 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add
793 parentheses.

822 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
823 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
824 --error-output, to avoid warnings with M4 2.0.
826 2006-09-19 Stepan Kasal <kasal@ucw.cz>
828 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be
829 consistent with _AH_CHECK_FUNCS and _AH_CHECK_HEADERS.
830 * lib/autoconf/headers.m4 (AH_CHECK_HEADERS_DIRENT): Likewise.
832 2006-09-15 Stepan Kasal <kasal@ucw.cz>
834 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Eliminate the
835 expansion of AC_CHECK_FUNCS.
837 2006-09-14 Stepan Kasal <kasal@ucw.cz>
839 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
840 mistaken comment: the path has to be relative; do not use
841 the path at runtime.
843 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
845 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the
846 argument to `--prefix' for sub-configure scripts.
847 Pass `--silent' to sub-configure scripts.
848 * tests/torture.at (Configuring subdirectories): Add tests
849 for both changes.
850 * doc/autoconf.texi (Setting Output Variables): Fix example to
851 not show `--silent' being passed to a `configure' re-run.
853 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
855 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
856 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
857 for the existence of the directory at configure-time. That's
858 too late, anyway. Problem reported by Stefan Seefeld.
860 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
861 7.1.4 /usr/bin/posix/sh described by Tim Rice in
862 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
864 2006-09-11 Stepan Kasal <kasal@ucw.cz>
866 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
867 works with GNU M4 1.4.3 again; make the normalized form
868 match the current m4 message; fix the description.
869 * test/tools.at (autom4te cache): Adapt to the change.
871 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
873 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
874 to catch glibc bug 2821
875 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
877 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
878 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
879 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
880 assume C89.
882 2006-09-08 Stepan Kasal <kasal@ucw.cz>
884 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the
885 preselections ...

894 2006-09-05 Paul Eggert <eggert@cs.ucla.edu>
896 * doc/autoconf.texi (Preset Output Variables): srcdir and
897 top_srcdir are not necessarily relative. Problem reported
898 by Dries Kimpe.
900 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
902 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
903 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
904 accept files with extension `.f'. For consistency, also prefer
905 xlf over f77.
906 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
907 from last patch.

924 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
926 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
927 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
928 except the first two arguments are reversed.
929 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
930 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
931 caches nor outputs a diagnostic. Suggested by Bruno Haible.
932 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
933 equivalent to the old AC_COMPUTE_INT.
934 (AC_COMPUTE_INT): No longer caches or reports. New signature.
935 All uses changed to AC_CACHE_CHECK_INT.
936 * tests/base.at (AC_CACHE_CHECK_INT): New test.

941 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
942 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
943 programs should use their Gnulib counterparts.
944 * doc/autoconf.texi (Particular Functions): Likewise.
945 (Macro Names, testsuite Invocation): Replace uses of these
946 obsolete macros with uses of non-obsolete macros.

970 simplify the code.
972 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
974 Fix Lex library problem reported to us by Julio Garvia.
975 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
976 for the default, which the user can override.
977 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
978 deal with LEXLIB.
979 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
980 didn't work if some values were cached but not others. Test for
981 broken lex libraries like native ia64-hp-hpux11.22; see
982 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
983 work around the problem by preferring an empty LEXLIB to -lfl or
984 -ll. Let the user set LEXLIB='' to indicate no library needed.
986 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
987 * README: Likewise.

1135 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1136 problems with arg script text that doesn't end in newline, and

1151 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1152 --help' should mention that `--version' outputs configuration
1153 settings. Report by Bruno Haible.
1155 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1157 Fix test suite failures reported by Pierre in

1173 less skeptical about "volatile", after discussion with
1174 Bruno Haible on bug-gnulib.

1176 leading white space from text. From Bruno Haible.
1178 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1180 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1181 compiler complains about it, even if things works after the
1182 complaint. Problem reported by Peter O'Gorman.
1184 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1185 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1186 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1188 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1190 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

1200 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1202 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1203 under AC_C_VOLATILE.
1204 (Volatile Objects): Be a little less skeptical about what
1205 "volatile" means. Derived from thoughts by Ben Pfaff in
1206 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1208 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1210 * doc/autoconf.texi: Fix some typos.
1212 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1214 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1215 more globally, since the 2006-06-30 patch didn't suffice. Problem
1216 reported by Keith Marshall. Also, don't bother with builddir2,
1217 since it shouldn't be needed any more.
1219 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1221 * doc/autoconf.texi (Generic compiler characteristics):
1222 Document AC_COMPUTE_INT. Fix wrong statements on Default

1236 * NEWS: Document previous change.
1238 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1240 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1241 Require that long long int be at least 64 bits wide. C99 requires
1242 this and enough programs depend on it so we should check for it.
1243 Bruno Haible reports in
1244 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1245 that long long int is 32 bits wide with some nonstandard compilers.
1246 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1248 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1250 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1251 to a nonexistent file, so that we don't have to worry about
1252 a local site configuration that doesn't use /usr/local.
1253 Problem reported by Keith Marshall in
1254 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1256 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1258 * doc/autoconf.texi: Be more consistent about using @acronym with
1259 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1260 quite right (it talked about "OSF/Tru64", even though the
1261 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1262 and it even mentioned "OSF 4"!) and at this point there's little
1263 reason to talk about OSF any more, since it died in 1994.
1264 (Specific Compiler Characteristics): Simplify example of
1265 negative-size array.
1266 (File Descriptors): Reorder to make the text flow better.
1267 Remove joke about "appreciate the various levels"; I didn't get it.
1268 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1269 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1270 (File Descriptors, Limitations of Usual Tools):
1271 Tone down the advice against renaming or removing open files.
1272 (Limitations of Usual Tools): Add a new section, on 'rm'.
1274 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1276 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1277 -lXt in LIBS, idea from Karsten Hopp; this was due since
1278 this change:
1280 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1281 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1282 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1283 (which belong to Xt, not X itself). See Debian bug 327655.
1285 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1287 * configure.ac (AC_INIT): Bump to 2.60a.

1301 quadrigraph correctly in traces.
1303 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1304 Fix typos.
1306 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1307 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1308 not defined.
1309 * doc/autoconf.texi (Changed Directory Variables): New node,
1310 to document the whole `datarootdir' business a bit better.
1311 * NEWS: Update.
1312 * tests/torture.at (datarootdir workaround): Extend test.
1313 Prompted by report by Alexandre Julliard.
1315 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1317 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility

1319 fix reported by Larry Jones.
1321 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1323 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1324 about literal '${datarootdir}' if a definition is found in the
1325 output file.
1327 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1329 * NEWS: Use "M4" rather than "m4" when appropriate.
1330 Problem reported by Eric Blake.
1331 * doc/autoconf.texi: Likewise.
1332 Use @acronym around BSD, GCC, and GNU when appropriate.
1333 (Why GNU M4): Renamed from "Why GNU m4".
1334 (Redefined M4 Macros): Mention that Posix
1335 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1336 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1337 to int.
1339 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1341 * bin/autom4te.in (handle_output): Do not forbid the empty
1342 pattern.
1343 * tests/tools.at (autoconf: the empty token): New test.
1345 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1347 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1348 calls, so that we do not care whether they are LIFO or FIFO;
1349 in the m4_wrap, do not check which diversion is the topmost
1350 one, just check that the stack is balanced at the end.
1351 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1352 base diversion forever--pop the previous diversion before
1353 opening the new one; consequently, remove the m4_wrap call.
1354 * lib/autotest/general.m4 (AT_INIT): Likewise.
1355 * tests/m4sugar.at: Do not use
1356 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1358 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1359 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1361 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1362 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1363 Rework example of m4wrap token-pasting trouble so that it doesn't
1364 care whether it's LIFO or FIFO.
1365 Fix some "contrary to"s that are awkward in English.
1367 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1369 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1370 to `yes' instead of `int$1_t' if the type is found, for more
1371 consistent configure output (where $1 is the number of bits).
1372 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1373 Suggested by Bruno Haible.
1375 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1376 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1377 with system headers. Report by Bruno Haible.
1379 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1381 * config/config.guess, config/config.sub: Sync from upstream.
1383 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1384 in order to avoid picking up an older installed frozen m4sh.m4f.
1385 Besides an outdated shell startup, this could have been created
1386 by an earlier M4 version with incompatible frozen file format.
1388 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1390 * README: Recommend m4 1.4.4 instead of 1.4.3..
1391 * doc/autoconf.texi: Likewise.
1392 (Special Chars in Names): Say that $(.FOO) is portable, as
1393 suggested by Stepan Kasal.
1394 (Installation Directory Variables, Build Directories):
1395 (Automatic Remaking, Subdirectories, Fortran Compiler):
1396 (Making testsuite Scripts, Defining Directories):
1397 Quote variable usages better.
1398 (Making testsuite Scripts): Add clean-local rule to makefile
1399 snippet, by Eric Blake.
1400 (Installation Directory Variables): Fix table item font.
1401 Reword slightly to clarify. Generalize advice about
1402 not using special characters to include all file-related
1403 vars, not just VPATH.
1404 (Special Chars in Variables): Warn about special characters in
1405 $(srcdir) too.
1406 (Assignments): Clarify default-value example as suggested by
1407 Ralf Wildenhues in
1408 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1409 (Special Shell Variables): Note leading ./ or ../, as suggested
1410 by Eric Blake.
1411 (Limitations of Builtins): Under cd, warn about CDPATH.
1412 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1413 Ralf Wildenhues.
1415 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1417 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1418 `@var', for texi2html.
1419 (Systemology): Some more word wrapping, for DVI output.
1420 (autom4te Invocation): The short option for `--melt' is `-M',
1421 not `-m'.
1423 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1425 * doc/autoconf.texi: More formatting and English tweaks,
1426 many suggested by Ralf Wildenhues.
1427 Reword to avoid "@code{...}'s" and the like, since it's ugly
1428 with Emacs info mode. discontents -> woes.
1429 Put a few "will"s back. time stamp -> timestamp.
1430 side-effect -> side effect.
1432 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1434 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1435 Warn about $@ not persisting. Problem reported by Julien Danjou in
1436 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1437 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1438 Mention other special chars, too.
1440 2006-06-14 Eric Blake <ebb9@byu.net>
1442 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1444 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1446 * doc/autoconf.texi: Some systematic minor improvements, as
1447 follows. Use "makefile" when talking about makefiles
1448 generally (which might be named "makefile" or "Makefile" or even
1449 "foo.mk"), "Makefile" when talking about a specific makefile
1450 called "Makefile". This unclutters the text from weird quotes
1451 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1452 values" rather than "@var{foo}s" and similar constructs containing
1453 "}s". Use "Make rules" rather than "Makefile rules". Minor
1454 English-language improvements. Change the prefix "sub-" to "sub"
1455 and "re-" to "re".
1456 Put blank lines around examples more consistently.
1457 Avoid "rather" and "very" as intensifiers.
1458 Avoid "will" as an auxiliary.
1459 (Limitations of Make): Split this node into....
1460 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1461 (Leading _ in Macro Names, Backslash-Newline-Newline):
1462 (Backslash-Newline Comments, Long Lines in Makefiles):
1463 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1464 (obj/ and Make, make -k Status, VPATH and Make):
1465 (VPATH and Double-colon, $< in Explicit Rules):
1466 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1467 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1468 New nodes, resulting from splitup of Limitations of Make.
1469 All cross-references changed. Raise the top node from
1470 a section to a chapter, and all subnodes accordingly.
1471 Redo the introductory wording to match the new organization.
1472 (Installation Directory Variables): Use an example that is
1473 closer to what Autoconf actually does. Mention that VPATH's
1474 value should not contain metacharacters or white space.
1475 (Fortran Compiler): Fix a VPATH bug in an example.
1476 (Leading _ in Macro Names): Mention that this problem is no longer
1477 of practical concern.
1478 (VPATH and Make): Reword the advice to make it clearer
1479 that Autoconf and Automake support VPATH in non-GNU make, but
1480 many packages have bugs in this area.
1481 ($< in Explicit Rules): Refer to Build Directories rather
1482 than using a (non-VPATH-safe) example.
1483 (Automatic Rule Rewriting): Mention the sort of disaster that
1484 can ensue with Solaris-style rule rewriting with VPATH.
1486 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1488 * doc/install.texi (Compilers and Options): Weaken the
1489 suggestion to use GNU make for VPATH builds.
1491 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1492 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1494 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1495 in regular expression.
1497 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1499 * doc/autoconf.texi (Installation Directory Variables):
1500 Drop extra @samp from `@table @samp' item.
1501 (Limitations of Usual Tools): Comment fix.
1502 Do not nest @samp just to point to other table items.
1503 (Writing testsuite.at) <AT_CHECK>: The second argument to
1504 `@dvar' is already @samp'ed.
1505 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1506 do not use @var in the second argument.
1508 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1510 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1511 $as_shell.exe too. Problem reported by Andreas Buening in
1512 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1514 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1516 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1517 `unused variable' compiler warning, for `-Wall -Werror'.
1518 Reported by Jaap Haitsma in
1519 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1521 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1523 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1524 case the compiler dumps core. Problem reported for
1525 OpenServer 5.0.7 by Tim Rice in
1526 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1527 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1528 Likewise.
1530 2006-06-06 Tim Rice <tim@multitalents.net>.
1532 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1533 "ERROR" only shows up in "make check" output if there is an
1534 error.
1536 2006-06-06 Eric Blake <ebb9@byu.net>
1538 * tests/tools.at (automatically allowed tokens): Fix typo.
1540 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1542 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1544 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1545 typically overflows on x86 CPUs, even though the C standard
1546 requires otherwise.
1548 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1550 * configure.ac (AC_INIT): Bump to 2.59e.
1551 * NEWS: Update.
1553 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1555 Version 2.59d.
1557 * config/texinfo.tex: Sync from upstream.
1559 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1560 seen, invoke libtoolize with `--ltdl' argument.
1561 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1562 * NEWS: Update.
1563 Suggested by Eric Blake.
1565 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1567 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1568 reported by Ralf Wildenhues.
1569 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
1571 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1573 * THANKS: Update.
1575 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1577 * doc/autoconf.texi: Modernize some of the references to Solaris.
1579 2006-06-05 Stepan Kasal <kasal@ucw.cz>
1581 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
1582 message issued by AC_REQUIRE.
1583 * tests/m4sugar.at: Check m4_require's error message.
1584 * tests/base.at: Check AC_REQUIRE's error message.
1585 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1586 to...
1587 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1588 AT_CHECK_M4.
1589 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1590 `expout' as the last parameter.
1591 * tests/tools.at: Adapt to the above change.
1593 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1595 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1596 information about race-free implementations of mkdir.
1598 2006-06-04 Eric Blake <ebb9@byu.net>
1600 * bin/autoreconf.in (help): Document M4 environment variable.
1601 * bin/autoconf.as (Usage): Likewise.
1602 * bin/autom4te.in (help): Likewise.
1603 * doc/autoconf.texi (autom4te Invocation): Likewise.
1605 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1607 * NEWS: GNU make now recommended for VPATH builds.
1608 Mention that some macros are now documented to be obsolescent.
1609 * doc/autoconf.texi:
1610 Prefer "current" to "modern" to describe
1611 currently-used (albeit perhaps old-fashioned) hosts.
1612 Mention which ancient features no longer need to be worried about.
1613 setgid -> set-group-ID
1614 setuid -> set-user-ID (these are the Posix terms)
1615 Fix some misuses of "only".
1616 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1617 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1618 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1619 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1620 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
1621 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
1622 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
1623 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1624 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1625 Mention that these macros are obsolescent.
1626 (Installation Directory Variables): shall -> should
1627 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1628 Mention that it's now safe to use 3 and 4.
1629 (Limitations of Usual Tools): cp -r is now specified by Posix.
1630 Omit longwinded and obsolescent discussion of cp -f.
1631 Modernize discussion of expr, ls.
1632 (Limitations of Make): Modernize discussion of VPATH builds.
1633 Mention $? as a workaround in some cases.
1634 * doc/install.texi (Basic Installation):
1635 Mention "./configure; make; make install" first. Be more
1636 specific about why this file is generic. Remove unnecessary
1637 parens. Remove misleading "only". Remove obsolete advice
1638 about csh. Don't say "configure" takes awhile; say it
1639 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1640 and CC=c99 rather than CC=c89, as these are blessed by current
1641 Posix. Recommend GNU make if doing a VPATH build.
1643 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1645 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1646 examples involving shell prompts.
1648 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1649 and Paul Eggert <eggert@cs.ucla.edu>
1651 * doc/autoconf.texi (Here-Documents): Add details about the
1652 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1653 use "here-documents" instead of "here documents".
1655 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1657 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1659 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1661 * doc/autoconf.texi (File System Conventions): Warn about ":"
1662 anywhere in directory names.
1664 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1666 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1667 about quoting the case statement, just in case.
1668 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1669 was fixed in ksh93g; reported by Ralf Wildenhues.
1671 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1673 * doc/autoconf.texi (System Services): Do not document
1674 overriding EXEEXT via ac_cv_exeext=ext.
1675 (Particular Programs) <AC_PROG_MKDIR_P>:
1676 Document that ${MKDIR_P} understands --.
1677 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1678 comment.
1680 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1682 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
1683 argument with leading hyphen. Problem reported by Paul Eggert.
1685 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1687 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
1688 about quoting ac_try: quote all of it, if any of it seems suspicious.
1689 This means we don't have to worry about ${ or sed any more.
1690 Also, double-quote the case statement, to work around misuses via
1691 underquoting as reported by Ralf Wildenhues in
1692 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
1693 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
1694 undocumented and dangerous macro.
1695 Problem reported by Ralf Wildenhues in
1696 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
1698 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1700 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
1701 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
1702 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
1704 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1706 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
1707 since evidently some packages rely on the old, broken behavior.
1708 Problem reported by Ralf Wildenhues in
1709 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
1710 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
1711 pre-2006-05-26 definitions, but leave in the comments that
1712 these macros are dangerous and should not be used.
1713 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
1714 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
1715 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
1716 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
1717 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
1719 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1721 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
1722 the use of 'tr', since this is our only use of 'tr'.
1724 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1725 and Paul Eggert <eggert@cs.ucla.edu>
1727 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
1728 Don't assume 'grep' works on long lines, since AIX grep doesn't.
1730 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1732 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
1733 the output file in the `${datarootdir}' test.
1735 2005-05-28 Stepan Kasal <kasal@ucw.cz>
1736 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1738 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
1739 mention of `datarootdir' in the input file(s), but literal
1740 `${datarootdir}' in the output file, and we haven't warned yet,
1741 then warn as well: the user may have (erroneously) used
1742 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
1743 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
1744 * tests/torture.at (datarootdir workaround): Extend this test.
1745 * NEWS: Update.
1747 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1748 and Paul Eggert <eggert@cs.ucla.edu>
1750 * doc/autoconf.texi (autoheader Invocation): The first argument to
1751 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
1752 alternatives and clear up the language a bit.
1754 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
1756 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
1757 ac_config_guess, ac_config_sub, ac_configure.
1758 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1759 Fix typo that prevented an unnecessary space from being removed.
1760 Problems reported by Ralf Wildenhues in:
1761 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
1763 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1765 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
1766 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
1767 Don't use the term "thread-safe" to talk about mkdir race
1768 conditions, since the problem is more a process than a thread
1769 issue. Problem reported by Stepan Kasal in:
1770 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
1771 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
1772 the test for 'install' more closely. Look at MKDIR_P first.
1773 Look in the PATH, and at /opt/sfw/bin.
1774 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
1775 Don't bother to try mkdir -p, since we already check mkdir --version;
1776 just look at the version number. (There's no easy way to check
1777 for race-free implementations.)
1778 * tests/tools.at (autoconf: subdirectories): Adjust to above
1779 changes, since MKDIR_P now might end in "/mkdir -p".
1781 * doc/autoconf.texi (autoheader Invocation): Mention that the
1782 first arg of AC_DEFINE_UNQUOTED must be a literal.
1783 Problem reported by Ben Pfaff in
1784 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
1786 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
1787 * doc/autoconf.texi (Special Chars in Variables): New section.
1788 (Preset Output Variables): Warn about special chars in CPPFLAGS.
1789 (Installation Directory Variables): Quote $(datadir) better.
1790 (Limitations of Builtins): Describe some of eval's trickiness.
1792 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
1793 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
1794 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
1795 in front of every arg, not just trailing args. Quote apostrophes.
1796 (_AC_EVAL_ECHO): New macro.
1797 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
1798 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
1799 removed.
1800 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
1801 exposed by quoting of eval argument. Put the command on line line
1802 so it logs better.
1803 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
1804 (_AC_PATH_X, AC_PATH_X): Quote more safely.
1805 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
1806 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
1807 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
1808 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
1809 Use eval more safely.
1810 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
1811 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
1812 to be replaced.
1813 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
1814 lines, exposed by quoting of eval argument.
1816 2006-05-26 Stepan Kasal <kasal@ucw.cz>
1817 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1819 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
1820 initialization of `ac_cv_exeext', do not override it if it was
1821 already set, unless it was set to `no', for compatibility with
1822 Autoconf-2.13, and comment this.
1823 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
1824 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
1825 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
1826 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
1827 Document that this test may be overridden by setting
1828 `ac_cv_exeext'.
1830 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1832 Revert these two patches:
1834 2006-04-06 Eric Blake <ebb9@byu.net>
1835 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1836 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1837 2006-04-01.
1839 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1840 Clean up _AC_COMPILER_EXEEXT* macros.
1841 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1842 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1843 ac_file to the name of the default output file and call
1844 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1845 initial `rm' of the candidate files...
1846 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1847 the same list in subsequent `rm' calls, and for the temporary
1848 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1849 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1850 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1851 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1852 no longer needed) by libtool. Make it a cache check.
1853 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1854 copied here by mistake.
1855 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1856 _AC_COMPILER_EXEEXT.
1857 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1858 _AC_COMPILER_OBJEXT directly.
1859 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1861 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1863 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
1864 Fix description of how the buggy `sed' works.
1866 2006-05-25 Noah Misch <noah@cs.caltech.edu>
1868 Sync from Automake:
1870 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
1871 ENOLCK. Only mention `make -j' when applicable. Only raise
1872 fatal errors when `make -j' is involved. Improve error message.
1874 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1876 * doc/autoconf.texi (Here-Documents): We now know more about
1877 the variable expansion in here documents bug.
1878 Thanks to Tim Rice and Stepan Kasal.
1880 * doc/autoconf.texi (Making testsuite Scripts): Add an example
1881 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
1883 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1885 * tests/autotest.at (Multiline command from M4 expansion):
1886 No failure to be expected if the shell quotes newlines in
1887 commands in the `set -x' output. Report by Tim Rice.
1888 * THANKS: Update.
1890 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1892 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
1893 expansion in the here-documents used by config.status, as that
1894 runs afoul of the Korn shell version M-12/28/93d bug described in
1895 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
1896 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
1897 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
1899 2006-05-23 Jim Meyering <jim@meyering.net>
1901 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
1902 Fix typo introduced with 2006-04-02 change. It reversed the sense
1903 of the test.
1905 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1907 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
1908 ac_dB slightly, to save bytes in the script.
1909 Max out at 50 lines, rather than 96; this is more likely
1910 (though not guaranteed) to avoid obscure 'sed' failures.
1912 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1914 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
1915 `tr -d -' as bad option argument. Work around this by deleting
1916 an unrelated character.
1917 Report by Tim Rice <tim@multitalents.net>.
1919 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
1920 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1921 Stepan Kasal <kasal@ucw.cz>
1923 * doc/autoconf.texi (Particular Programs): Do not promise that
1924 we always prefer the GNU version of the program, and that we
1925 search according to PATH; both rules can have exceptions.
1926 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
1927 AC_PROG_SED. Move descriptions of limitations
1928 to the Limitations of Usual Tools section.
1929 (Limitations of Usual Tools) <sed>: Mention script length
1930 limitations with Solaris /usr/ucb/sed.
1931 <grep>: Fix wording for empty alternative. Mention that -c and
1932 -l should not be combined, and that -E and -F should not be
1933 combined.
1935 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1936 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1938 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
1939 limits in Solaris 8 /usr/ucb/sed by testing a long script.
1941 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1943 * doc/autoconf.texi (Defining Symbols): Literal parameter of
1944 AC_DEFINE is now passed to m4_pattern_allow.
1945 * NEWS: Mention that; likewise for AC_SUBST.
1946 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
1947 the parameter to m4_pattern_allow.
1948 * tests/tools.at: Add a check for that.
1950 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1952 * lib/autoconf/status.m4: Fix typos.
1954 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1956 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
1957 only the files that this macro generates.
1959 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1961 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
1962 the HP-UX sed limitation of 99 commands, labels do not count.
1963 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
1964 in the comment.
1965 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
1967 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1969 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1970 Import the following fix from coreutils:
1972 2006-01-13 Jim Meyering <jim@meyering.net>
1974 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
1975 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
1976 not double-quote uses of that variable, to accommodate the rare
1977 case in which getmntent is available in none of the libraries
1978 checked. This happens at least on FreeBSD 5.0.
1980 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
1982 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
1983 ac_config_guess, ac_config_sub, and ac_configure, since evidently
1984 some other programs unwisely rely on these undocumented vars.
1985 But put in warning comments about them.
1986 Problem reported by Ralf Wildenhues in
1987 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
1988 * NEWS: Document that these variables are intended to go away.
1990 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1992 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
1993 and set the language to C++ (analogous to the equivalent Fortran
1994 tests).
1996 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
1997 * doc/autoconf.texi (C++ Compiler): Document it.
1998 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
1999 * NEWS: Update.
2001 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2003 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2004 that caused config.status to generate 100-command sed scripts; the
2005 portable limit is 99.
2007 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2009 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2010 variable `ac_d' instead of `d' to avoid infringing namespace.
2011 Report by Ralf Menzel.
2013 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2015 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2016 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2017 * tests/tools.at (autoconf: subdirectories): New test, taken from
2018 the corresponding problem report by Ralf Wildenhues in:
2019 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2021 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2022 Quote some uses of shell variables if they might suffer unexpected
2023 globbing. This doesn't fix all instances of quoting problems that
2024 I found, just the easy ones that look safe.
2025 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2026 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2027 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2028 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2029 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2030 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2031 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2032 Likewise.
2033 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2034 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2036 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2038 * bin/autoreconf.in ($help): Reword according to the manual.
2039 Suggested by Olly Betts.
2041 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2042 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2044 * bin/autoreconf.in: Pass the directory argument to
2045 `require_configure_ac'. Fix comment.
2046 * tests/torture.at (Configuring subdirectories): Expose this.
2047 Reported by Olly Betts.
2049 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2051 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2052 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2053 Automake as follows:
2055 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2056 `$configure_in' instead of `configure.in', to preserve
2057 directory component.
2059 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2061 * config/config.guess, config/config.sub, config/texinfo.tex,
2062 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2064 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2066 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2067 test for C99 conformance; (bool) 0.5 is an integer constant
2068 expression, but (bool) -0.5 is not. Problem reported by Fedor
2069 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2071 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2073 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2074 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2075 Warn about obsolete install-sh files. Remove stray sentence
2076 fragment and fix cross reference.
2077 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2078 install -d; this undoes the 2006-05-10 change.
2079 (MKDIR_P): Mark with AN_MAKEVAR.
2080 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2081 that we don't require $INSTALL to be thread-safe. Move comments
2082 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2083 of AC_PROG_INSTALL. Output a message saying that we're checking
2084 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2085 MKDIR_P instead of AC_SUBST.
2086 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2087 Special magic for MKDIR_P, too.
2088 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2089 a dnl.
2090 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2092 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2094 Sync from Automake, as follows:
2096 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2097 * config/install-sh: Initialize IFS, so field splitting isn't
2098 turned off later.
2099 * config/mkinstalldirs: Likewise.
2100 * config/missing: Remove superfluous quotes. Replace all uses of
2101 `[' by `test', for consistency, and for..
2102 * config/missing (sed_minuso, sed_output): New variables.
2103 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2104 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2105 Fixes `missing' to detect `--output' for help2man. Fixes
2106 PR automake/483. Report by Dennis J. Linse.
2107 (autom4te): Document in `missing --help'.
2109 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2111 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2112 * config/install-sh: Don't use 'path' to talk about file names,
2113 as per GNU coding standards. Close a race condition reported by Ralf
2114 Wildenhues and Stepan Kasal. There is still a race condition
2115 on hosts that predate Posix 1003.1-1992, but we can't help this.
2116 Don't mishandle weird characters like space on pre-Posix hosts.
2117 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2118 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2119 AC_PROG_MKDIR_P from AS_MKDIR_P.
2120 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2121 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2122 earlier editions are not (including Automake 1.8.3).
2123 Do not suggest mkinstalldirs for thread-safety.
2124 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2125 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2126 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2127 presence of special characters and race conditions.
2128 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2129 in Autoconf's name space.
2131 2006-05-10 Bruno Haible <bruno@clisp.org>
2132 and Paul Eggert <eggert@cs.ucla.edu>
2134 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2135 from Automake with minor changes.
2136 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2138 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2140 * config/install-sh: Update to Automake CVS version, as follows:
2141 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2142 * lib/install-sh: Simplify the expr implementation of dirname.
2143 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2144 * lib/install-sh: Handle --, and diagnose unknown options.
2146 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2148 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2149 `./autom4te' to create `./testsuite', since the `all' target
2150 will ensure its presence, but `installcheck' should not create
2151 the uninstalled wrappers.
2153 * tests/torture.at (Unusual Automake input files): Skip if we
2154 detect automake < 1.8.
2156 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2158 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2159 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2160 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2161 * NEWS: Update.
2163 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2165 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2166 munge (multiple) white space and other oddities.
2167 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2168 single quotes in variable assignment.
2169 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2170 and similar failures by adding multiple spaces, tabs, and other
2171 special characters.
2172 Report and different test suggested by Francesco Romani
2173 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2175 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2176 single quotes, we only need to search for single quotes; this
2177 both simplifies the search pattern, and makes us less
2178 susceptible to `echo' variations for arguments not containing
2179 single quotes.
2180 (_AC_ARG_VAR_VALIDATE): Likewise.
2182 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2184 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2185 `$*' and IFS concatenation issue with traditional shells and
2186 bash-2.04. Report by Seanster@Seanster.com.
2188 2006-05-03 Bruno Haible <bruno@clisp.org>
2190 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2191 precisely which Mac OS X versions have the od problem.
2193 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2195 * doc/autoconf.texi: Use @option systematically.
2197 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2198 and Bruno Haible <bruno@clisp.org>
2200 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2201 about 'od'.
2202 (Integer Overflow): Mention the special case of integer division
2203 overflow.
2205 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2207 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2208 traditional shells like the Solaris one that do not use the
2209 first IFS character for assembling `$*'.
2210 Prompted by a related report from autoconf_bug@nro.ca.
2212 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2213 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2215 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2216 Mention more problems with the -e option.
2218 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2220 * NEWS: Typo.
2221 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2223 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2224 in URLs to improve DVI formatted output (requires texinfo 4.6).
2225 (System Services, Systemology, Shellology): Likewise.
2226 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2227 output.
2229 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2230 continuous text.
2231 (Runtime): Fix macro argument names to match description:
2232 `action-if-found' -> `action-if-true' and similarly.
2233 (Obsolete Macros): Likewise.
2234 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2235 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2236 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2238 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2240 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2242 * ChangeLog: Typo.
2243 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2244 DVI output.
2246 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2248 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
2249 /bin/sh set unsorted output.
2250 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
2251 * tests/local.at: Likewise.
2253 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
2255 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2256 (Integer Overflow, Null Pointers, Buffer Overruns):
2257 (Floating Point Portability, Exiting Portably): New sections.
2258 (Writing Test Programs): Fix some langauge. Recommend exiting
2259 with status 1, not merely nonzero. Clarify exit declaration.
2260 (Run Time): Move C exit status stuff to new Exiting Portably section.
2261 (Systemology): Mention Posix and levenez. Update v7 reference.
2262 (Portable Shell): Mention the Posix shell.
2264 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2266 * bin/autoconf.as (me): Replace by as_me.
2268 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2270 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2271 since as_me isn't set yet.
2273 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2275 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2276 a few minor bugs in this area.
2278 * doc/autoconf.texi (Programming in M4sh): Comment out the
2279 documentation of AS_BASENAME, for now.
2280 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2281 (Limitations of Builtins) <basename>: Do not refer to
2282 AS_BASENAME.
2283 * bin/autoconf.as (me): Don't use AS_BASENAME.
2284 (dir): Remove the unused variable.
2285 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2286 AS_DETECT_REQUIRED. All uses changed.
2287 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
2288 All uses changed.
2289 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
2290 (AS_BASENAME): Use "basename --" to protect against leading "-".
2291 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
2292 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2293 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2294 (_AS_DIRNAME_PREPARE): Likewise.
2295 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
2296 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2297 (AS_DIRNAME): Use "dirname --".
2299 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2301 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2302 of "run time" and "run-time" changed to "runtime", for consistency.
2303 * lib/autoconf/fortran.m4: Likewise (in comment).
2304 * lib/autoconf/functions.m4: Likewise.
2305 * lib/autoconf/general.m4: Likewise.
2306 * lib/autoconf/headers.m4: Likewise.
2308 * doc/autoconf.texi (Run Time): Document the exit status situation
2309 with more accuracy and detail.
2311 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2313 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2314 Archive is not officially `GNU' any more. Update URL.
2315 (Defining Directories): Likewise
2316 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2318 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2320 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2321 newline from the `trap' code to finish `config.log'; the NetBSD
2322 /bin/sh resets the exit status after an empty command, as
2323 documented in doc/autoconf.texi.
2324 Reported by Dalibor Topic <robilad@kaffe.org>.
2326 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2328 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2329 Suggested by Bruno Haible.
2331 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2333 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2334 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2335 Instead, just list the shells that we know work.
2336 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2337 changed. Be more cautious about the _cv_ variable.
2338 * tests/tools.at (Syntax of the shell scripts): Check the
2339 _cv_ variable once, at first, to avoid an internal autoconf error
2340 when sh -n does not work.
2342 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2344 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2346 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2348 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2349 use ">&-" since we're only 99.999% sure that this is portable,
2350 and since the MinGW bug is fixed in a different way.
2351 * lib/autotest/general.m4 (AT_INIT): Likewise.
2353 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2355 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2356 before opening config.log, to avoid hitting a bug on MinGW.
2358 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2360 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2361 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2362 This works around a MinGW bug reported by Eric Paire.
2363 Make sure that all writes to the log file append to it,
2364 rather than possibly losing data.
2365 * lib/autotest/general.m4 (AT_INIT): Likewise.
2367 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2369 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2370 description.
2372 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2374 * NEWS: Update.
2376 * configure.ac (AC_INIT): Bump to 2.59d.
2378 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2380 Version 2.59c.
2382 * Makefile.maint (news-date-check): Do not require a leading `*'
2383 before the release date in NEWS.
2385 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2386 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2388 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2389 the instantiated file do not contain the string 'datarootdir'
2390 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2391 @mandir@, replace the reference '${datarootdir}' by the value.
2392 * tests/torture.at (datarootdir workaround): New test.
2393 * NEWS: Advertise this temporary fixup.
2394 Based on a patch by Bruno Haible, reported and analyzed by
2395 Paul Eggert and Noah Misch.
2397 2006-04-12 Eric Blake <ebb9@byu.net>
2399 * tests/autotest.at (Debugging a failed test): Fix comment.
2401 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2403 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2404 all the changes since 2006-04-07.
2406 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2408 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2409 succeeded, but `ln -s file dir' failed, take care to remove the
2410 leftover target before the next test, to prevent its spurious
2411 failure; also make sure `ln file dir' works before selecting it.
2412 Thanks to Keith Marshall for pointing this out.
2413 * THANKS: Update.
2415 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2416 assignments in `at_debug_args', so that we put them correctly
2417 in the `run' script.
2418 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2419 Reported by Eric Blake.
2421 2006-04-11 Eric Blake <ebb9@byu.net>
2423 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2424 top-level tests after micro-suite has been run. Used in...
2425 (Debugging a successful test, Debugging script and environment),
2426 (Debugging a failed test): ...these new tests. The first of these
2427 is fixed by...
2428 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2429 macro, split out from...
2430 (AT_INIT): ...here, so that using -d also generates a run script.
2431 Document that -d inhibits top-level logging.
2432 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2433 inhibits top-level logging; debug scripts are created.
2435 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2436 check.
2437 * tests/autotest.at (Empty test, Empty check): New test to check it.
2439 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2440 from gcc.
2442 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2444 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2445 the files if a problem appears. Make the empty *.at files
2446 read-only, too. Proposed by Ralf Wildenhues.
2448 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2450 * config/Makefile.am: Add comment to force updated Makefile.in.
2452 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2453 space only patch to this file, this patch causes the Makefile.in
2454 files that include freeze.mk to be updated, and thus have a
2455 newer time stamp again, which in turn makes a pristine CVS
2456 checkout have correct time stamps.
2458 * Makefile.maint (cvs-sv): New macro, to be used..
2459 (config.guess-url_prefix, config.sub-url_prefix)
2460 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2461 point to CVS text checkout of Gnulib files.
2462 (copyright-check): Bump current year.
2463 (announcement): Do not hard-wire `./announce-gen'.
2464 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2465 correctly.
2466 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2467 `chmod +x'.
2468 (wget_files): Update config.guess, config.sub, texinfo.tex by
2469 `wget-update', now that their URLs work again.
2471 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2473 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2474 Problem noted by Paul D. Smith.
2476 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2478 * doc/autoconf.texi: Remove unused words from word list.
2479 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2480 .x-sc_trailing_space: New files.
2482 * doc/standards.texi: Sync from gnulib.
2484 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2485 `LIBOBJDIR' as experimental.
2487 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2488 with a target directory; it's internally implemented as `cp'
2489 anyway, but since Autoconf advertises the possibility to use
2490 a target directory when LN_S is `ln -s', we need to find out.
2491 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2492 analyzed by Keith Marshall <keith.marshall@total.com>.
2494 * THANKS: Update.
2496 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2498 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2499 confdefs.h as-is. In general, if it has backslash-newline or the
2500 like, then it doesn't work either to sort or to remove empty
2501 lines.
2503 2006-04-09 Stepan Kasal <kasal@ucw.cz>
2505 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
2507 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
2509 * lib/autom4te.in (Automake-preselections): Preselect
2510 _AM_SUBST_NOTMAKE.
2512 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2514 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2515 apostrophe within a single-quoted string, as this is the usual
2516 tradition and is easier to read than '"'"'. Don't rely on the
2517 shell treating "$/" like '$/'. Use a more-consistent indenting
2518 style for the trap.
2520 2006-04-09 Eric Blake <ebb9@byu.net>
2522 * tests/autotest.at (Backquote command substitution),
2523 (Multiline backquote command substitution): Remove mistaken
2524 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2525 applied...
2526 (Parenthetical command substitution, Multiline parenthetical
2527 command substitution): here.
2529 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2531 Import macros from gnulib (often changing their name).
2533 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
2534 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
2535 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

2538 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
2539 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
2540 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
2541 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
2542 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
2543 The manual mentions Gnulib more prominently.
2544 * doc/autoconf.texi (Gnulib): New node.
2545 (Pointers): Add Gnulib URL.
2546 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
2547 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
2548 Gnulib section.
2549 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
2550 suggest a #define rather than a typedef for _Bool, and mention
2551 Gnulib rather than trying to substitute stdbool code.
2552 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
2553 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
2554 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
2555 AC_STRUCT_DIRENT_D_TYPE.
2556 (Particular Types): Mention stdint.h and inttypes.h as standard
2557 headers too.
2558 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
2559 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
2560 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
2561 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
2562 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
2563 (C Compiler): Move AC_C_LONG_DOUBLE to ...
2564 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
2565 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
2566 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
2567 (Coding Style). Don't mention m4_expand_once.
2568 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
2569 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
2570 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
2571 (AC_CHECK_FUNCS): Use it.
2572 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
2573 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
2574 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
2575 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
2576 (AC_HEADER_ASSERT): New macro.
2577 (AC_HEADER_STDBOOL): Don't assume "#error" works.
2578 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
2579 Catch a bug in an HP-UX C compiler.
2580 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
2581 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
2582 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
2583 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):
2584 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
2585 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
2586 New macros.
2588 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
2589 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
2591 2006-04-08 Stepan Kasal <kasal@ucw.cz>
2593 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
2594 of the warning introduced by the 2001-08-28 change.
2596 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
2597 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2599 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
2600 variables shall be overriden by the cache.
2601 * tests/torture.at (AC_ARG_VAR): Test also with a first value
2602 that contains braces.
2604 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2606 Revert the patch from 2006-04-01 and only improve
2607 _AS_DETECT_BETTER_SHELL:
2609 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2610 skip nonexistent directories.
2611 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2612 only shell candidates which exist.
2613 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2614 * lib/autotest/general.m4 (AT_INIT): No need to give three
2615 parameters to _AS_PATH_WALK.
2617 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2618 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2620 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2621 distinguish m4sugar macros.
2622 * tests/tools.at (autoupdating with aclocal and m4_include):
2623 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2624 test case by Noah Misch <noah@cs.caltech.edu>.
2626 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2628 Revert my change from 2006-03-17, in other words:
2629 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
2630 and DUALCASE=1.
2631 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
2632 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
2633 it is set.
2635 2006-04-07 Eric Blake <ebb9@byu.net>
2637 * doc/autoconf.texi (Programming in M4sh): Document that
2638 AS_MKDIR_P exits the script on failure.
2639 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2641 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2643 * config/elisp-comp, config/install-sh, config/mdate-sh,
2644 config/missing, config/mkinstalldirs: Sync from Automake.
2646 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
2647 from Automake.
2649 * doc/make-stds.texi: Sync from gnulib.
2651 2006-04-06 Eric Blake <ebb9@byu.net>
2653 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2654 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2655 2006-04-01.
2657 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
2658 Eric Blake <ebb9@byu.net>,
2659 Paul Eggert <eggert@cs.ucla.edu>,
2660 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2662 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2663 whether `set' quotes correctly: redirect stderr of the tested
2664 `set', and use a subshell, for Ultrix; use `sed' instead of
2665 `grep' for zsh `set' which may write binary output; match only
2666 at the beginning of a line, to avoid false positives.
2667 In order to avoid false positives by unrelated variables with
2668 multiline content, put the dump algorithm in a subshell and
2669 unset all variables containing newlines (except some which are
2670 special to the shell). Warn about cache variables that are
2671 unset.
2673 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2675 * config/config.guess, config/config.sub, config/texinfo.tex:
2676 Sync from upstream.
2678 * tests/mktests.sh: Reword comments.
2680 * tests/mktests.sh: Only skip internal macros starting with
2681 `_AC_' or `__AC_'. Noted by Stepan Kasal.
2682 Update exclusion lists for the test suite to this end:
2683 (AC_ARG_VAR): Do test this now.
2684 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
2685 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
2686 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
2687 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
2689 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
2690 shell issue with double-quoted command substitutions of native
2691 commands.
2692 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
2693 Marshall.
2695 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
2696 no file matches the glob, discard the warning, set `nullglob'.
2697 (syntax-check): Likewise.
2698 (sc_cast_of_x_alloc_return_value): Likewise.
2699 (sc_cast_of_alloca_return_value, sc_error_exit_success)

2874 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2875 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2876 ac_file to the name of the default output file and call
2877 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2878 initial `rm' of the candidate files...
2879 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2880 the same list in subsequent `rm' calls, and for the temporary

2882 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2883 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2884 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2885 no longer needed) by libtool. Make it a cache check.
2886 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2887 copied here by mistake.
2888 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2889 _AC_COMPILER_EXEEXT.

2926 subordinate tools.
2927 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
2928 * doc/autoconf.texi (autoreconf Invocation): Document it.

2964 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
2965 switch all of them on and of when necessary. Fixes the bug when
2966 m4sugar macros (e.g., m4_define) were expanded after the first

3018 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
3020 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3618 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3620 * NEWS: Move AH_HEADER mention to right place.
3622 2005-10-27 Stepan Kasal <kasal@ucw.cz>
3624 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
3625 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3627 2005-10-25 Stepan Kasal <kasal@ucw.cz>
3629 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
3630 conftst2.$ac_objext.
3631 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3633 2005-10-24 Stepan Kasal <kasal@ucw.cz>
3635 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
3636 conftest.o, to see whether the compiler really obeys; rm the object
3637 file before and after the test and register it with ac_clean_files.
3638 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3640 2005-10-21 Stepan Kasal <kasal@ucw.cz>
3642 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
3643 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
3644 code so that the most common case requires less forks.
3646 2005-10-20 Stepan Kasal <kasal@ucw.cz>
3648 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
3649 not portable; thanks to Paul Eggert and Alexandre.
3651 * NEWS: Fix an old typo.
3653 2005-10-20 Jim Meyering <jim@meyering.net>
3655 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
3656 the latter'', in two places.
3658 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
3660 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
3661 AC_LANG_PROGRAM, fixing a typo. Don't give details about
3662 the inner workings of AC_LANG_FUNC_LINK_TRY.
3663 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
3664 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
3665 by the function rather than ignoring it.
3666 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
3667 comparing its address. Intel's interprocedural optimization was
3668 outsmarting the old heuristic. Problem reported by
3669 Mikulas Patocka.
3671 2005-10-19 Stepan Kasal <kasal@ucw.cz>
3673 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
3675 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
3677 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
3678 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
3680 2005-10-04 Stepan Kasal <kasal@ucw.cz>
3682 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
3683 before removing it (chmod -R u+rwx); there are three instances of this.
3685 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3686 Stepan Kasal <kasal@ucw.cz>
3688 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
3689 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
3690 make its content writable before removing it. Remove an errorneous
3691 comment from the end, where the logs of the failed tests are copied
3692 to the main log file.
3694 2005-09-27 Stepan Kasal <kasal@ucw.cz>
3696 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
3697 in case the computer is too quick. Double quote the configure.ac
3698 snippets.
3700 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
3701 problems if the testsuite were running too fast.
3703 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3705 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3706 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3707 (which belong to Xt, not X itself). See Debian bug 327655.
3708 * NEWS: Mention this.
3710 2005-09-07 Stepan Kasal <kasal@ucw.cz>
3712 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
3714 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
3716 * config/move-if-change: Don't output "$2 is unchanged";
3717 suggested by Ben Elliston. Handle weird characters correctly.
3719 2005-09-06 Stepan Kasal <kasal@ucw.cz>
3721 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
3722 calls, so that the final expansion of this macro is shorter.
3723 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
3724 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
3725 the cleanup there. Use AS_VAR_* macros, to be more general.
3726 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
3728 * lib/autoconf/general.m4: Use AS_IF where appropriate.
3730 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
3732 2005-09-01 Stepan Kasal <kasal@ucw.cz>
3734 * doc/autoconf.texi (Configuration Headers): Add an index entry
3735 for AH_HEADER.
3737 2005-08-26 Pavel Roskin <proski@gnu.org>
3739 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
3740 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
3741 running xmkmf.
3743 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
3745 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3746 The previous patch didn't work, so try a better one.
3748 2005-08-26 Stepan Kasal <kasal@ucw.cz>
3750 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
3751 in the example. Reported by Bruno Haible.
3752 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
3753 "if $undefined_var;" succeeds with my shell.
3755 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
3756 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
3757 but change the m4_divert_text to m4_divert_once.
3759 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
3761 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3762 Work around bug in Solaris /usr/xpg4/bin/awk.
3763 The bug is present in at least Solaris 8 through 10.
3765 2005-08-24 Stepan Kasal <kasal@ucw.cz>
3767 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
3768 some evil values and relying on the fact that $* concatenates the
3769 parameters by the first character from IFS.
3771 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3772 Stepan Kasal <kasal@ucw.cz>
3774 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
3775 first header appears, define AH_HEADER.
3776 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
3777 Update limitations about when to call AC_CONFIG_HEADERS.
3778 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
3779 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
3780 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
3781 ``Configuration Actions''; fix their index entries.
3783 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
3784 options correctly. Process N-M as M-N if M is smaller than N.
3785 Process ranges correctly so that N-N will run only N.
3786 Sort and uniquify the tests that will be run. If there is more
3787 than one test, reinsert the banners for the tests.
3788 * tests/autotest.at (Keywords): Unmark XFAIL.
3790 2005-08-23 Stepan Kasal <kasal@ucw.cz>
3792 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
3793 before passing the macro name to AH_TEMPLATE.
3795 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
3796 now opens log after option processing; in particular, --version
3797 and --help do not touch config.log.
3799 * Makefile.maint: Revert the change from 2005-08-12.
3801 2005-08-22 Stepan Kasal <kasal@ucw.cz>
3803 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
3804 common code to...
3805 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
3807 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3809 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
3810 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
3811 Language cleanup.
3813 * doc/autoconf.texi (Defining Symbols, Changed Results):
3814 Prepend to LIBS, not append, in examples.
3816 2005-08-16 Stepan Kasal <kasal@ucw.cz>
3818 When building in place, set srcdir="."; suggested by Tim Van Holder.
3820 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
3821 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
3822 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
3823 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
3824 does not mean "no --srcdir option".
3826 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3828 * tests/autoscan.at (autoscan): New file.
3829 * tests/suite.at: Use it.
3830 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
3831 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
3833 * tests/autotest.at (Keywords): Test keywords combinations.
3835 2005-08-12 Stepan Kasal <kasal@ucw.cz>
3837 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
3838 add "2>&1"; gzip 1.2.4 prints help on stderr.
3840 2005-07-27 Stepan Kasal <kasal@ucw.cz>
3842 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
3843 was pushdef'ed twice while popped only once. Push it only once.
3844 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
3846 2005-07-26 Stepan Kasal <kasal@ucw.cz>
3848 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
3849 prefixed by mere "===", not "configure: === ".
3851 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
3853 * Makefile.maint: Update from Bison.
3855 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
3856 "<tab>" in comment, so that the point is understandable.
3858 2005-07-25 Stepan Kasal <kasal@ucw.cz>
3860 Rewrite substantial part of lib/autoconf/status.m4.
3861 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
3862 and CONFIG_COMMANDS are not processed in four separate loops.
3863 Instead, there is one main loop. This alows that the common code
3864 is expanded only once, thus config.status (and configure) is smaller.
3866 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
3867 the AC_LIST_FILES and cousins macros are no longer used.
3869 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
3870 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
3871 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
3872 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
3873 contain the initialization, nor the for loop, nor the associated
3874 commands; all these go to ...
3875 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
3876 _AC_OUTPUT_CONFIG_STATUS.
3877 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
3878 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
3879 (_AC_OUTPUT_FILE): The creation of the sed script ...
3880 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
3881 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
3882 _AC_OUTPUT_MAIN_LOOP.
3883 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
3884 _AC_CONFIG_COMMANDS): Use ...
3885 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
3886 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
3887 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
3888 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
3889 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
3890 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
3891 ... new macros.
3892 (_AC_CONFIG_UNIQUE): Update.
3893 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
3894 Replaced by this ...
3895 (_AC_LIST_TAGS): ... new common macro.
3896 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
3897 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
3898 (_AC_LIST_TAG_COMMANDS): ... new common macro.
3899 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
3900 this didn't belong to the `config commands' section.
3901 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
3902 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
3903 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
3904 to the `config commands' section either.
3905 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
3906 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
3908 ... and many changes to the comments nearby.
3910 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
3911 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
3912 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
3913 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
3914 (#define header templates): The comment at the top of the generated
3915 header now includes the name(s) of the source file(s).
3917 Several unrelated small changes:
3919 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
3920 parameter to AC_DIAGNOSE.
3921 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
3922 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
3923 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
3924 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
3925 with AU::AC_OUTPUT.
3926 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
3927 in AC_OUTPUT doesn't double-quote it either.
3928 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
3929 parameters.
3931 2005-07-10 Stepan Kasal <kasal@ucw.cz>
3933 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
3934 versions of Portland Group compiler produce single- and double-quoted
3935 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
3936 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
3938 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3940 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3941 This is a corrected version of yesterday's patch.
3943 2005-07-07 Stepan Kasal <kasal@ucw.cz>
3945 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
3946 path, too; insert a "===" to emphasize the line.
3948 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
3949 ac_cv_build_alias to ac_build_alias.
3950 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
3952 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
3953 change eliminates it. Problem reported by Alexandre Duret-Lutz.
3954 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
3955 (AC_ARG_VAR): ... here.
3956 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
3957 target_alias.
3959 Keep a list of all precious variables and process them with one simple
3960 for loop, instead of expanding all commands, or, OTOH, complicated
3961 processing of output of "set".
3962 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
3963 variable names in new macro...
3964 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
3965 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
3966 a loop to assign all ac_env_* and ac_cv_env_* variables.
3967 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
3968 to INIT_PREPARE.
3969 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
3970 its value to shell variable ac_precious_vars and call
3971 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
3972 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
3973 _AC_ARG_VAR_VALIDATE.
3975 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
3976 and the AC_SUBSTs ...
3977 (AC_INIT): ... here.
3979 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
3980 the ac_subst_files section in config.log.
3982 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
3984 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

3989 * tests/c.at (C keywords): Test AC_C_TYPEOF.
3991 Fix problems reported by Nicolas Joly.
3992 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
3993 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3994 They are generated by the Tru64 v5.1B shell.
3996 2005-07-05 Stepan Kasal <kasal@ucw.cz>
3998 Fix my changes from 2005-07-01; reported by Noah Misch.
3999 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
4000 description, the macro now accepts only a single tag.
4001 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
4003 Fix cases when the varsions of Autoconf and Autotest don't match.
4004 Reported by Noah Misch.
4005 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
4006 at_top_builddir, for compatibility with older autotest.
4007 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
4008 is not set, use at_top_builddir, for compatibility with older
4009 versions of autoconf.
4011 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4013 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
4014 Problem reported by Patrick Welche.
4016 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4018 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4019 sed substitution command, so that we allow | in program prefixes
4020 and program suffixes. (& is a problem anyway; we're not fixing
4021 that here.)
4022 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4023 configure_input, top_builddir, srcdir, etc.
4024 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4025 PATH_SEPARATOR in AUTOTEST_PATH.
4027 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
4029 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
4030 for loop over config.site files using `set', to allow
4031 directory names containing IFS characters.
4033 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
4035 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
4036 directories with weird names. Apparently some people like living
4037 on the edge. However, improve the test that "pwd" actually does
4038 report a name for the working directory.
4039 * NEWS: Remove the claim that we test for funny chars in dir names.
4041 2005-07-01 Stepan Kasal <kasal@ucw.cz>
4043 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
4044 replaced ...

4053 about #include <config.h>.
4054 (Generic Functions): Mention the Gnulib project.
4055 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
4057 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
4058 document to output the default config_* lists to config.status.
4059 Don't recognize option --file, if the functionality is not there.
4060 Likewise for --header; moreover, recognize --he and --h as shortcuts
4061 for --help in that case.
4063 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4064 matches the order of execution. No code changed.
4066 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4086 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4087 (AC_SUBST): Call it.
4088 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4089 the directory specific variables; but don't call it for configure_input.
4091 2005-06-28 Derek Price <derek@ximbiot.com>
4093 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4094 addition.
4096 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4098 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4099 directory have inherent problems with special characters like spaces,
4100 due to limitations in Make syntax. Problem reported by Alexandre
4101 Duret-Lutz.
4102 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
4103 Also, fix Tru64 porting problem with shell patterns,

4115 from Justace Clutter.
4116 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4117 variable into diagnostic. Make the diagnostic an error, not a warning,
4118 because we really don't support spaces and suchlike in dir names.
4119 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4120 Don't worry about backslashes in srcdir; it can't happen now.
4121 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
4122 Simplify ac_optarg handling.

4133 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
4134 that '\|' is not allowed in BREs; recommend using newline separated
4135 list of patterns instead of multiple -e options.

4147 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4148 b, t, r, w commands require single space, while : cannot have any.
4149 (Special Shell Variables): Fix sed code this in the example.
4150 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4151 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4153 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4154 expand to the empty list. Don't use two pairs of m4_changequote,
4155 it's not necessary.
4157 2005-06-20 Derek Price <derek@ximbiot.com>
4159 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
4161 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
4163 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4164 * doc/autoconf.texi:
4165 Don't mention Solaris versions so much, if a
4166 problem is common to all extant versions of Solaris. Say "SunOS
4167 4" instead of "SunOS" for SunOS 4.
4168 (awk): Mention more of the limitations of traditional Awk.
4169 (cat): Don't talk about cat -v.
4171 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
4173 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
4174 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
4175 but the implementation is entirely different and is designed
4176 to be compatible with glibc strverscmp.
4177 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4179 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4180 on Mac OS X 10.4 reported by Peter O'Gorman in:

4182 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
4183 Use shell builtins rather than 'expr', to work around expr bug.
4185 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4187 * doc/autoconf.texi: "filesystem" -> "file system".
4188 "behaviour" -> "behavior".
4189 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
4190 * lib/autoconf/general.m4: Omit blank after ":" sed command,
4191 as per POSIX.
4192 * lib/m4sugar/m4sh.m4: Likewise.
4193 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
4194 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
4196 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4197 (.x.1): Ignore the time stamp in the .TH line when deciding whether
4198 to update the man page. That way, we don't have to check in new
4199 man pages every month.
4201 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
4202 quotes and backslashes. Patch from Derek Price.

4207 AS_TR_SH.
4209 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
4211 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4212 -u, since it outputs chatter if the input files are the same.
4213 Problem reported by Ralf Menzel.
4215 2005-06-08 Derek Price <derek@ximbiot.com>
4217 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4218 renaming them since they are about to be redefined anyhow.
4220 2005-06-08 Derek Price <derek@ximbiot.com>
4222 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4223 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4224 Move m4_undefine to alphabetical order.
4226 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4228 * README: Recommend GNU M4 1.4.3 or later.
4229 * doc/autoconf.texi (Introduction): Likewise.
4230 Reword to avoid some formatting glitches.
4231 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4232 Clarify explanation of HP compiler bug.
4233 Redo example output tp match current CVS snapshot.
4234 Use @example.org in email addresses when the examples
4235 might get inadvertently cut-and-pasted into user code.
4236 Remove example of autom4te usage that doesn't seem to work now.
4237 Use modern AC_INIT (except when the example is meant to be
4238 shown with Autoconf 2.13).
4239 Update ksh info for Solaris 9 and later.
4240 KB -> kB.
4241 Modernize description of Automake versions a bit.
4242 Don't claim a future version of Autoconf is near.
4243 * doc/install.texi: Reword to avoid some formatting glitches.
4245 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4247 * doc/autoconf.texi: Add [] to examples, so that the manual
4248 follows its own advice about quoting better.
4249 Reword to avoid some formatting glitches.
4250 * doc/installt.exi: Reword to avoid some formatting glitches.
4252 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4253 Tru64 ksh pattern matching bug. Reported against Libtool by
4254 Albert Chin <libtool@mlists.thewrittenword.com> and
4255 Nicolas Joly <njoly@pasteur.fr>.
4257 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4259 m4_cdr of one-member list was [[]] (one-member list containing an
4260 empty string) instead of [] (an empty list. Callers were skewed to
4261 match this misbehaviour. As a consequence of this:
4262 - m4_foreach([x], [], [foo]) expanded to `foo', while
4263 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4264 This bug has been fixed:
4266 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4267 expand to an empty string; print error msg if called without
4268 an argument list.
4269 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4270 misbehaviour; handle [] and [[]] correctly.
4272 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4274 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

4276 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4278 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4280 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4281 swallow records with more than 99 fields.
4282 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4283 parse the long line.
4285 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4287 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4288 swallow literals longer than 399. Reported by Ralf Wildenhues.
4289 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4290 to workaround this limitation.
4292 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4294 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4295 to gfortran, and make these the first two compiler names
4296 checked (following the general autoconf preference for gcc).
4298 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4300 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4301 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4302 (testsuite): Make sure autotest.m4f is up-to-date before using it.
4304 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
4306 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4307 expression of unbounded size when processing the --list
4308 option. This runs afoul of a limit of 399 bytes per regular
4309 expression on AIX. Problem reported by Ralf Wildenhues.
4311 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
4313 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
4314 * doc/autoconf.texi (Particular Headers): Reword example
4315 for multiline stdbool replacement.
4316 (Setting Output Variables): Reword text a bit. Don't
4317 give all the details about |#_!!_#|.
4318 Reword description of line replacement.
4320 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4322 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4323 now contain newlines, and substituted files must be referenced on
4324 a line alone; the sed scripts to substitute them are now very
4325 different.
4326 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4327 commands can be put in a sed script portably.
4328 * doc/autoconf.texi (Setting Output Variables): Document above
4329 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4330 use of multiline substitution.

4340 * tests/local.at: Don't attempt to check for negated character
4341 classes in shell scripts. The test was too brittle.
4343 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4345 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4346 * doc/autoconf.texi (Limitations of Builtins): Document this
4347 limitation.
4349 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4351 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4352 common code; used in many places in the tree.

4354 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
4356 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
4358 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
4359 messages when ac_unique_file is not found.
4360 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4361 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4362 commands, for consistency with AC_MSG_ERROR and such.
4364 * bin/autoconf.as: Make more use of "shift 2" in option processing.
4366 * bin/Makefile.am: Merge the two rules for creating scripts.

4374 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4376 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4377 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4378 (ac_top_builddir): ... this ...
4379 (ac_top_build_prefix): ... to this; the old name is also kept, for
4380 backward compatibility.
4381 (ac_top_builddir_sub): New variable, without the trailing slash,
4382 always nonempty.
4383 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4384 * doc/autoconf.texi (Configuration Actions): Rename
4385 ac_top_builddir to ac_top_build_prefix.
4386 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
4387 at_top_builddir to at_top_build_prefix.

4395 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4397 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4398 argument to m4_foreach. I guess it was necessary in the past,
4399 but I think it's a no-op now.
4401 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4403 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4404 ``cat <<_ACEOF'' commands to one.
4405 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4406 * lib/autoconf/status.m4: On various places, use expr instead of
4407 ``echo|sed.''
4408 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4409 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4410 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4411 a range.
4412 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for

4414 code had false positives.
4416 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4418 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
4419 as on 2005-05-02.
4420 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:

4482 * doc/autoconf.texi (Autoconf Language): Be more precise about
4483 quoting rules. Problems noted by Stepan Kasal.
4484 Also, throughout this document, be more careful about white space.
4485 "blank", "white space", and "space" all have different meanings
4486 and we should be careful to say what we mean.
4488 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
4490 Fix C++ related problems reported by Werner Lemberg.
4491 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

4514 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
4516 * doc/autoconf.texi (Autoconf Language): Add more description
4517 about quoting heuristics.
4518 (Limitations of Builtins): Describe "set -" problems.
4520 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4522 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
4523 not newline.
4525 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
4526 by AC_DEFINE; it was a mistake.
4527 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
4529 2005-04-25 Stepan Kasal <kasal@ucw.cz>
4531 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
4533 2005-04-22 Stepan Kasal <kasal@ucw.cz>
4535 * doc/autoconf.texi (External Software): Quadrigraphs are not
4536 processed correctly in AS_HELP_STRING; avoid this in the examples.
4537 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4538 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
4539 comment and reduce m4_default([foo], []) to [foo].
4540 (m4_strip): Update the explanation.
4542 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4544 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
4545 Remove core.conftest.* too; it's generated by Tru64 5.1.
4546 Problem reported by Jennis Pruett.
4547 * lib/autoconf/functions.m4
4548 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4549 Don't bother to remove core files; AC_RUN_IFELSE should do that
4550 for you.
4552 2005-04-19 Stepan Kasal <kasal@ucw.cz>
4554 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

4571 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
4573 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
4574 as well as configure.in. Problem reported by Gregorio Guidi.
4576 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
4578 * doc/autoconf.texi (Particular Functions): Use gnulib's current

4592 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
4594 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4596 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
4597 Merge `-z option' as well for the benefit of Solaris link flags. Pass
4598 whole-archive (-zallextract, -zdefaultextract) options in the hope of
4599 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
4600 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
4602 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
4604 * NEWS: The configure command now warns you if you attempt to use
4605 a directory whose name contains a special character like space,
4606 newline, or "\".
4607 * doc/autoconf.texi (Installation Directory Variables): Allow
4608 "," in file names. Do not use \@; it's not a portable regexp.
4609 * bin/Makefile.am (edit): Likewise.
4610 * lib/Makefile.am (edit): Likewise.
4611 * tests/Makefile.am (edit): Likewise.
4612 * tests/semantics.at: Likewise.

4617 unportable file names.
4618 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4619 (AC_INIT): Use it.
4620 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4621 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4622 ac_pwd, and quote srcdir.
4623 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4625 * doc/autoconf.texi: Fix some systematic formatting problems.
4626 ".)" needs a following @: if not at the end of a sentence, and
4627 similarly for "!)". "etc." should be preceded by a comma.
4628 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4630 2005-03-22 Bruno Haible <bruno@clisp.org>
4632 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4633 argument is often called 'build-aux'.
4635 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4637 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4638 macro AC_TRY_LINK is obsolete.
4639 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4640 `AC_CONFIG_FILES'.
4642 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4644 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4645 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4646 from a Common Lisp's `cl'.
4647 (AC_PROG_CXX): Behave according to the documentation: don't
4648 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4649 make the variable CCC precious; use `cl.exe', not `cl'.
4651 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4652 Alexandre Duret-Lutz <adl@gnu.org>
4654 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4655 /dev/null, as "configure" shouldn't read stdin, and this insulates
4656 us from problems (e.g., when testing for "cl"). Also, do this
4657 redirection before invoking "hostname" or "uname", and keep the
4658 original input stream available via...
4659 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4660 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4661 bother with "</dev/null" since it's now done at the top of
4662 'configure'.
4663 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4664 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

4668 * tests/base.at (Input/Output): New test.
4670 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4672 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4673 newline if neither \c nor -n work, as that would output two
4674 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4676 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4678 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4679 This causes that any required macros inside will get before the if.
4680 * doc/autoconf.texi (autom4te.cache): A typo.
4682 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
4684 Undo previous change, except keep the change to
4685 lib/autoconf/programs.m4 that replaced grep with shell
4686 pattern-matching. This is because net-snmp configure reads stdin.
4687 Reported by Noah Misch.
4689 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
4691 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
4692 from /dev/null, as "configure" shouldn't read stdin, and this
4693 insulates us from problems (e.g., when testing for "cl").
4694 Suggested by Alexandre Duret-Lutz. Also, do this redirection
4695 before invoking "hostname" or "uname".
4696 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4697 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
4698 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
4699 "</dev/null" since it's now done at the top of 'configure'.
4700 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4701 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4702 Also, replace grep with shell pattern-matching, to save a process.
4704 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
4706 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4707 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
4708 avoid thinking that Allegro Common Lisp's "cl" command is a C++
4709 compiler.
4711 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
4713 * doc/autoconf.texi (Limitations of Usual Tools): Document that
4714 grep -q isn't portable. Improve grep -s explanation.
4715 Problem reported by Dan Manthey.
4717 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
4719 * doc/autoconf.texi (Special Shell Variables): Clarify
4720 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
4722 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4724 * doc/autoconf.texi: Use @acronym for DJGPP.
4725 Fix some @code's that should have been @env's, and vice versa.
4726 Sort environment variable names.
4727 Mention that shells no longer inherit IFS.
4728 Don't recommend PATH_SEPARATOR=';' so strongly.
4729 Mention that $RANDOM might expand to the empty string.
4730 "symlink" and "soft link" -> "symbolic link".
4731 Improve mktemp description (reported by Bruno Haible).
4733 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
4735 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
4736 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
4737 Likewise.
4738 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
4739 Likewise.
4741 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
4743 * NEWS: Mention AT_COPYRIGHT.
4745 * tests/local.at (AT_CMP): Use diff directly on input files rather
4746 than copying them.
4748 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
4749 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
4751 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4752 and Paul Eggert <eggert@cs.ucla.edu>
4754 * tests/autotest.at (Empty test suite): New test.

4756 (Substitute a 2000-byte string, Define to a 2000-byte string)
4757 (Substitute a newline, Define a newline): New tests.
4759 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4761 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
4762 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
4763 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
4764 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
4765 (Standard regular expressions): New test.
4766 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
4767 excess test name quoting.
4768 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
4769 CPPFLAGS to `configure' instead of setting it in `configure'.
4771 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
4772 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
4773 on some platforms.
4775 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
4776 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
4778 * tests/local.at (AT_CMP): New macro.
4779 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.

4783 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
4784 * tests/c.at (Extensions): Do not exit early.

4804 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
4806 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
4807 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
4809 Try not to generated lines of unlimited length, as POSIX places a
4810 2047-byte limit on line length of portable text files.
4811 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
4812 Use newline as a separator, not space.
4813 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
4814 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
4815 space.
4817 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4819 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
4820 as_func_*. Add test to check whether positional parameters
4821 are restored after function return.
4823 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
4825 * doc/autoconf.texi (Special Shell Variables): Mention _,
4826 BIN_SH, DUALCASE. Say that variables other than "status" are safe
4827 if they contain a lower-case letter. The DUALCASE problem was
4828 reported by Ralf Wildenhues.
4830 * bin/autoconf.as: Don't exit with status 0 after write failure
4831 with --help or --version.
4832 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
4833 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.

4837 * doc/autoconf.texi (Limitations of Usual Tools):
4838 Unicos 9 sed limitations.
4839 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
4840 to get the option-enhanced interface on older Crays. Try ftn for
4841 Fortran 95 (newer Crays).
4843 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
4845 * man/Makefile.am (.x.1): Go back to the simple solution, but take
4846 care to echo the commands, so the user knows what's going on.
4847 Modified from a suggestion by Stepan Kasal.
4849 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
4850 with a cross reference. Derived from a suggestion by Bruce Korb.
4852 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
4854 * doc/autoconf.texi (config.status Invocation): Warn about
4855 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
4856 * doc/install.texi (Defining Variables): Likewise.
4857 Based on a proposed patch by Ralf Wildenhues.
4859 * man/Makefile.am (.x.1): Make sure the required generated files
4860 are up to date. Problem and original solution proposed by Stepan Kasal.
4861 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
4862 implicit-man-prerequisites): New rules, used by the above.

4868 2005-01-29 Stepan Kasal <kasal@ucw.cz>
4870 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
4871 Update the long comment explaining it.
4873 m4_require no longer writes an ``is required by'' line to the
4874 execution stack. It contains only one bit of non-redundant
4875 information: that the macro was required, not called. And even
4876 this bit is useless in most situations: have you ever met a macro
4877 which both calls and requires the same macro?
4879 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
4880 (_m4_defun_pro_outer): ... only via this macro, for the outermost
4881 macro.
4882 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
4883 (m4_expansion_stack_pop): Remove the misplaced comment.
4884 (m4_require): Don't put the ``is required by'' line to the
4885 execution stack; slightly improve the out-of-a-defun error message.
4886 (_m4_divert_grow): New macro, counter for the temporary diversions.
4887 (_m4_require_call): Use it.
4888 * tests/m4sugar.at (m4_require): Expect output without the
4889 ``is required by'' messages.
4891 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4893 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
4894 rather than x for expr.
4896 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
4897 this is safe.
4898 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
4899 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

4909 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
4910 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
4911 from masters, so that FileUtils.pm's update_file provide --force
4912 support.
4913 * bin/autoheader.in: Pass $force to update_file so that
4914 config.h.in is always recreated when --force.
4916 2005-01-24 Stepan Kasal <kasal@ucw.cz>
4918 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
4920 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
4922 * doc/autoconf.texi (Limitations of Builtins): Clarify that
4923 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
4925 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
4927 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
4928 Warn about newline stripping in `` and $(). Update Solaris
4929 version to 9.
4930 (Limitations of Builtins): Use expr "X...", not expr "x...", as
4931 X insulates us from future changes to Posix.
4932 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
4933 stripping.
4935 2005-01-19 Stepan Kasal <kasal@ucw.cz>
4937 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
4938 you cannot use AC_DEFINE to define macros containing `[' or `]'.

4953 ulongval to be static, to avoid unwanted GCC warning. Problem
4954 reported by Michael Jennings via Daniel Reed; see
4955 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
4957 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
4959 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

5299 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5300 "char c = '\200';" rather than "char c = 0x80;" as the

5425 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
5426 three args in examples. Problem reported by Frederik Fouvry in:
5427 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
5428 Also, fix some minor spacing and punctuation bugs.
5430 2004-09-02 Akim Demaille <akim@epita.fr>
5432 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
5433 "case" to restore ordering.
5434 Reported by Stepan Kasal.
5436 2004-08-26 Akim Demaille <akim@epita.fr>

5448 * README: Add advice about m4 1.4.2.
5450 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
5451 texinfo.tex for now (done by hand now).
5452 * Makefile.maint (wget_files, cvs_files):
5453 Remove ansi2knr.c; nobody uses it.
5454 (ansi2knr.c-url_prefix): Remove.
5455 (cvs-update): Fix test for failure. I don't know why it ever
5456 worked...
5458 * doc/autoconf.texi: Update URLs, some of which went stale.
5459 Use @uref rather than @href.
5461 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
5462 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
5464 * config/config.guess, config/config.sub, config/elisp-comp,
5465 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
5466 doc/fdl.texi, doc/standards.texi: Sync with master copy.
5468 * NEWS, TODO, configure.ac, bin/autoscan.in,
5469 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
5470 doc/install.texi, lib/Autom4te/Configure_ac.pm,

5474 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
5475 tests/tools.at, tests/torture.at:
5476 Use "file name" rather than "filename" or "path",
5477 to be consistent with the terminology of the GNU coding standards.
5479 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
5481 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
5482 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
5483 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
5484 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
5486 More fixes to support spaces in the name of the build directory.
5487 This isn't a complete fix but it's an improvement.
5489 * bin/autoconf.as (autom4te_options): New var.
5490 Use it instead of appending to AUTOM4TE, so that we can allow
5491 spaces in the build directory's absolute name.
5492 * bin/autoheader.in ($autoconf): Allow spaces in file names.
5493 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
5494 AT_CHECK_NOESCAPE): Likewise.
5495 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
5496 main program): Likewise.
5498 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
5500 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
5501 From Ralf Corsepius in:
5502 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
5504 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
5506 * doc/autoconf.texi (Function Portability): Document isinf and
5507 and isnan. From a suggestion by Kevin Ryde.
5509 * lib/Autom4te/General.pm (END): Return correct exit status even
5510 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5512 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5514 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5515 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5516 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5518 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5520 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5521 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5522 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5523 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5524 * lib/autom4te.in (Automake-preselections): Preselect
5525 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5527 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5529 * lib/autom4te.in (Automake-preselections): Preselect
5530 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5531 trace them.
5533 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
5535 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
5536 Tru64.
5537 * doc/autoconf.texi (Shellology): Mention BIN_SH.
5538 Document problem with "`""`" in pdksh POSIX mode.
5540 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5542 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5543 with pdksh, too. Problem reported by Patrick Welche via
5544 Gary V. Vaughan.
5545 * doc/autoconf.texi (Shellology): Note that set -o posix is
5546 useful for pkdsh, too.
5548 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5550 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5551 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5552 Don't fail if ENV or BASH_ENV is readonly.
5553 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5554 etc. are read only. Problem reported by Ludovic Courtes.
5556 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5558 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5559 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5560 (trivial change)
5562 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5564 * doc/autoconf.texi (File System Conventions): Warn about
5565 names like "aux". Problem reported by Eric Blake.
5567 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5568 by zero instead of array size, so that we can use any arithmetic
5569 constant expression (instead of requiring an integer constant
5570 expression). This allows us to test expressions like DBL_MAX <
5571 LDBL_MAX, which didn't conform to the C standard using the old
5572 method.
5573 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5574 now that we can do floating-point tests at compile time.
5576 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5578 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5579 and LDBL_EPSILON, as the resulting expression isn't an
5580 integer constant expression and violates the C standard.
5581 Problem reported by Nelson H. F. Beebe. Also, check
5582 for "L" suffix, and check that long double doesn't have
5583 worse range or precision than double, that mixed-mode
5584 arithmetic doesn't generate a diagnostic, that double
5585 constants fit in long double.
5587 2004-06-03 Kevin Ryde <user42@zip.com.au>
5589 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5590 malloc(0) and realloc(NULL,size).
5592 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5593 Bob Proulx.
5595 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5597 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5598 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5599 by Jim Meyering.
5601 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5603 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5604 can be rewritten using if-then-else. Suggested by Bruno Haible.
5606 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5608 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5609 Problem reported by Stepan Kasal.
5611 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5613 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5614 change). Patch reported by Ralf Wildenhues in
5615 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5617 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5618 function F exists if the compiler and linker let you compile an
5619 expression like (F != 0). Recent versions of GCC optimize away
5620 the reference to F in that case, since every function address must
5621 be nonzero, so the link succeeds even if F does not exist.
5622 Problem reported by Manu in
5623 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5625 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5626 "Unix". Many uses changed.
5627 (Limitations of Builtins): Explain better why the ! command isn't
5628 portable.
5630 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
5632 * lib/autom4te.in (Automake-preselections): Preselect
5633 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5635 2004-05-19 Kevin Ryde <user42@zip.com.au>
5637 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5638 referencing AC_FUNC_STRERROR_R.
5640 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5641 note pessimistic assumption when cross compiling.
5643 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5645 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5646 (until 2004) invoked subcommands with sh -e, contra POSIX.
5647 Reported by Kevin Ryde.
5649 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5651 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5652 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5653 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5654 `test -f " /usr/bin/grep"', which _always_ failed.
5655 (AC_PROG_SED): Ditto bogus PATH fix.
5656 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5657 requires that grep correctly supports _multiple_ `-e' options, rather
5658 than stating only that grep should accept `-e'.
5660 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5662 Port to C99, which requires that 'exit' be declared.
5664 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5665 to ensure that stdlib.h is included.
5666 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5667 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5668 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5669 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5670 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5671 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5672 when using 'exit' in a test; C99 requires that 'exit' be declared.
5674 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5676 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5677 now prefers 'grep' implementations that accept -e.
5678 (Limitations of Usual Tools): Describe problems of traditional
5679 egrep and fgrep with long input lines, and of traditional grep
5680 with -e.
5681 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
5682 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
5683 All callers changed. Append /usr/xpg4/bin to the PATH, for
5684 Solaris.
5685 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
5686 the user with complaints about multiple -e options.
5687 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
5688 Define it with AC_PROG_GREP.
5689 * configure.ac (AC_PROG_GREP): Add.
5690 * lib/freeze.mk (GREP): New macro.
5692 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
5694 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
5695 a possible candidate only after all others fail, rather than
5696 consulting it first. This improves backward compatibility by
5697 better reflecting the way shell selection occurred in previous
5698 versions of Autoconf, and should help to avoid triggering latent
5699 problems in other packages, such as the one in Automake where zsh
5700 is not handled robustly:
5701 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
5702 Although it is not Autoconf's responsibility to work around
5703 problems in Automake, it nevertheless makes sense to avoid
5704 introducing unnecessary incompatibilites.
5706 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
5707 Gary V. Vaughan <gary@gnu.org>
5709 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
5710 how deeply nested we are when a suitable tool is found, set the
5711 ac_path_TOOL_found flag.
5712 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
5713 nested we are in this macro. Break out of all 3 nested loops if
5714 ac_path_TOOL_found is set.
5716 2004-04-21 Gary V. Vaughan <gary@gnu.org>
5718 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
5719 of the _AS_PATH_WALK loop too if GNU flavor is found.
5721 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
5723 * doc/autoconf.texi (Limitations of Make): Update documentation
5724 for `$<'. New entry `Long lines', based on a report from Simon
5725 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
5726 paragraph about DJGPP, based on a mail from Richard Dawe.
5728 2004-04-20 Paul Eggert <eggert@twinsun.com>
5730 * tests/c.at (C keywords): Don't assume that GCC supports
5731 "restrict" and "inline", as sufficiently-old GCC versions do not
5732 (also, GCC configured to be in pedantic C89 mode does not).
5733 Problem reported by Sumit Pandya in:
5734 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
5736 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
5737 consider -g to work if it generates warnings when plain compiles
5738 don't. Problem reported by Braden McDaniel in:
5739 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
5741 * doc/autoconf.texi (Slashes): New section, to document a problem
5742 reported by Jim Meyering in:
5743 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
5745 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
5746 linker output files before linking, to work around IRIX 6 linker bug.
5747 Problem reported by Rainer Orth in:
5748 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
5750 2004-04-20 Gary V. Vaughan <gary@gnu.org>
5752 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
5753 best tool so far counter rely on the tool path variable name to
5754 avoid checks for one tool being affected by the results of running
5755 the length check on a previous tool.
5757 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
5758 match expression argument, as different greps have different
5759 regular expression flavours.
5760 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
5761 literals.
5762 (AC_PROG_EGREP): Pass 'EGREP$'.
5763 (AC_PROG_GREP): Pass 'GREP$'.
5765 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
5767 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
5768 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
5770 2004-03-29 Paul Eggert <eggert@twinsun.com>
5772 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
5773 Types, Specific Compiler Characteristics, System Services,
5774 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
5775 etc. consistently instead of 'long', 'short', 'unsigned' etc.
5776 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
5777 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
5778 Likewise.
5779 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
5780 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
5781 AC_TYPE_OFF_T): Likewise.
5782 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
5783 Likewise.
5785 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
5786 pacify libtool 1.5.2. Fix quoting problems in sed command.
5788 2004-03-28 Paul Eggert <eggert@twinsun.com>
5790 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
5791 now defines HAVE_DECL_TZNAME if it is declared, when
5792 HAVE_STRUCT_TM_TM_ZONE is not defined.
5793 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
5794 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
5795 for HAVE_TZNAME.
5797 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
5799 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
5800 superfluous backslashing of quotes (") in sed expressions;
5801 thanks to Paul Eggert.
5803 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
5805 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
5806 Fortran compiler is ifort, also added pghpf; thanks to Nelson
5807 H. F. Beebe for the bug report.
5809 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
5811 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
5812 quoted -cmdline argument in Portland Group compiler (bug
5813 reported by Jeffrey J. Barteet).
5815 2004-03-25 Kevin Ryde <user42@zip.com.au>
5817 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
5818 (Run Time): ... here, where it's now mentioned.
5820 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
5822 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
5823 inherits from language Autoconf-without-aclocal-m4.
5824 (Customizing autom4te): Adjust example; the cache must now be
5825 disabled for language Autoconf-without-aclocal-m4.
5827 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
5828 Nathanael Nerode <neroden@twcny.rr.com>
5830 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
5831 AC_CHECK_TOOLS): Warn if a cross-tool is found without
5832 a prefix.
5833 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
5834 AC_CHECK_TARGET_TOOLS): New macros.
5835 * doc/autoconf.texi (Generic Programs): Document
5836 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
5837 AC_CHECK_TARGET_TOOLS, and warn for future changes
5838 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
5839 AC_CHECK_TOOLS.
5840 (Specifying Names): Document the reason for these future
5841 behavioral changes.
5842 * tests/mktests.sh: Do not generate tests for the
5843 new macros.
5844 * NEWS: Document these changes.
5846 * doc/autoconf.texi: Avoid macros with unbraced arguments,
5847 they make TeX hang up.
5849 2004-03-15 Paul Eggert <eggert@bogus.example.com>
5851 * NEWS: New macro AC_CHECK_ALIGNOF.
5852 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
5853 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
5854 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
5855 vowel.
5856 (AC_CHECK_ALIGNOF): New macro.
5857 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
5858 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
5859 those for sizeof.
5861 2004-03-03 Paul Eggert <eggert@twinsun.com>
5863 * bin/Makefile.am (edit): Don't use $< in a context where
5864 POSIX doesn't require support for it. Use $@.in instead.
5865 Problem reported by Anthony N. Frasso in
5866 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

5872 from the next generation of Libtool.
5873 * lib/autom4te.in (Autoreconf-preselections): Ditto.
5875 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5877 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
5878 is not always thread-safe. Report from Nathanael Nerode.
5880 2004-02-18 Paul Eggert <eggert@twinsun.com>
5882 Fix a dependencies problem, stemming from a Autoconf 2.59 build
5883 problem on QNX reported by Stephen Rasku in
5884 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
5886 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
5887 $(m4sh_m4f_dependencies); this removes a FIXME.
5888 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
5889 (MAINTAINERCLEANFILES): Split into pieces,
5890 one per related section. Add $(srcdir)/wrapper.in.

5895 AC_SUBST provides no portable way to escape literal newlines.
5897 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
5898 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
5899 Darwin uses -lcrt2.o and there's little point to cataloging all
5900 the system variants. Partial fix reported by Andreas Waechter in:
5901 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
5902 for bug reported by Nelson H. F. Beebe in:

5905 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
5907 * doc/autoconf.texi (AU_DEFUN): Fix English,
5908 suggested by Paul Eggert.
5909 * lib/autoconf/autoupdate.m4: Correct reference to
5910 acobsolete.m4, suggested by Alexandre Duret-Lutz.
5912 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
5914 * bin/autoupdate.in: Define __file__ so that warnings
5915 refer to the correct file.
5916 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
5917 the behavior of the third argument.
5918 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
5919 correctly the behavior of the third argument. Document
5920 what the three macros that AU_DEFUN defines do. Fix
5921 warning message when the third argument includes $0
5922 (reported by Alexandre Duret-Lutz).
5924 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5925 Eric Sunshine <sunshine@sunshineco.com>
5926 Paul Eggert <eggert@twinsun.com>
5928 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
5929 (AS_INIT): Output shell initialization there. Removed optional
5930 parameter. Expand _AS_SHELL_FN_SPY.
5931 (AS_INIT_WITH_SHELL_FN): Removed.
5932 (_AS_SHELL_FN_SPY): New macro.
5933 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
5934 macros.
5935 (AS_SHELL_SANITIZE): Remove loop to find better shell
5936 and documentation for the parameter.
5937 (_AS_DETECT_BETTER_SHELL): Move it here.
5938 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
5939 (_AS_RUN): Move it here, support testing with eval.
5940 (AS_REQUIRE_SHELL_FN): Require shell functions when
5941 it is used.
5942 (_AS_LINENO_WORKS): Put around braces, we do not
5943 trigger the bash bug anymore.
5944 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
5945 use AS_INIT_WITH_SHELL_FN.
5946 * bin/autoconf.in, tests/wrapper.in: Regenerated.
5948 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5950 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
5951 * doc/autoconf.texi: Don't say that the third parameter
5952 is broken.
5953 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
5954 (AU_DEFUN): Honor the third parameter, create autoupdate
5955 macros with AU_DEFINE.
5956 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
5957 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
5958 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
5959 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
5960 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

5965 * lib/autoconf/status.m4: Remove FIXME.
5966 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
5967 that the macro is not present anymore in the updated
5968 configure.ac.
5969 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
5970 of autoupdate.
5972 2004-01-28 Paul Eggert <eggert@twinsun.com>
5974 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
5975 copyright years.
5976 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
5977 2003 (except 1997) to the list of copyright years. This undoes
5978 the 2003-05-22 change, which removed the older years from the list.
5979 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
5981 2004-01-27 Gary V. Vaughan <gary@gnu.org>
5982 Albert Chin-A-Young <china@thewrittenword.com>
5984 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
5985 grep or ggrep program in PATH that accepts as long lines as
5986 possible.
5987 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
5988 AC_PROG_GREP.
5989 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
5990 egrep and fgrep respectively if $GREP -E/-F don't work.
5991 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
5992 _AC_PROG_GREP, and AC_PROG_SED.
5993 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
5994 longest input length accepted by a command.
5995 (AC_PROG_SED): Use it.
5996 * doc/autoconf.texi (Particular Programs): Document the changes.
5997 * NEWS: Updated.
5999 2004-01-27 Paul Eggert <eggert@twinsun.com>
6001 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

6003 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
6004 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
6006 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
6007 bin/autoconf.in, config/Makefile.in, config/config.guess,
6008 config/config.sub, config/install-sh, config/mdate-sh,

6019 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
6020 tests/actypes.at: Regenerate and/or sync with original
6021 sources.
6023 2004-01-26 Paul Eggert <eggert@twinsun.com>
6025 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6026 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6027 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6028 not <inttypes.h>. Problem reported by Tim Mooney in
6029 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6030 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6031 Likewise.
6033 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6034 otherwise "make check" fails because it forbids cmp (I guess
6035 because cmp treats files as binary on DOS-like systems).
6037 * tests/mktests.sh: Update copyright date to 2004, since some tests
6038 have changed in 2004.
6040 2004-01-23 Gary V. Vaughan <gary@gnu.org>
6042 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
6043 non-truncating sed or gsed program in PATH.
6044 * tests/acprograms.at: Add it.
6045 * doc/autoconf.texi (Particular Programs): Document it.
6046 * NEWS: Updated.
6048 2004-01-15 Paul Eggert <eggert@twinsun.com>
6050 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6051 -std1 disables some useful extensions on Tru64. Problem reported
6052 by N. Lichtmaier in
6053 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6055 2004-01-14 Paul Eggert <eggert@twinsun.com>
6057 * doc/autoconf.texi (Programming in M4sh): Document that
6058 AS_MKDIR_P succeeds if the destination is a symbolic link
6059 to an existing directory.
6060 (Limitations of Usual Tools): Note that mkdir -p might not
6061 succeed on symlinks to directories.
6063 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6065 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6066 * bin/autoheader.in: Grammar fix in message.
6067 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
6068 Test for dir before calling mkdir -p. (trivial changes)
6070 2004-01-13 Eric Blake <ebb9@byu.net>
6072 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
6073 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6075 2004-01-10 Jim Meyering <jim@meyering.net>
6077 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6079 2004-01-09 Paul Eggert <eggert@twinsun.com>
6081 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6082 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6083 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6084 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6085 AC_COMPILE_IFELSE, since we now assume our caller invokes
6086 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6087 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6088 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6089 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6091 2004-01-07 Paul Eggert <eggert@twinsun.com>
6093 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6094 `"'...'"`, as it's confusing (and I suspect it may not work on
6095 some platforms). The code was incorrect anyway, as it assumed
6096 that \$ evaluated to itself in that context. Reported by
6097 Alexandre Duret-Lutz.
6099 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6101 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
6102 and _LT_AC_TAGCONFIG.
6104 2004-01-06 Paul Eggert <eggert@twinsun.com>
6106 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6107 example, and add more examples. Reported by Eric Sunshine.
6109 2004-01-05 Paul Eggert <eggert@twinsun.com>
6111 * doc/autoconf.texi (Limitations of Usual Tools):
6112 Remove warning against "rm -fr" introduced yesterday; it
6113 was a false alarm.
6115 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6116 autoscan, autoupdate, ifnames): Don't use chmod -w.
6117 * lib/Makefile.am (autom4te.cfg): Likewise.
6118 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6119 "chmod -w".
6121 2004-01-04 Paul Eggert <eggert@twinsun.com>
6122 Paolo Bonzini <bonzini@gnu.org>
6124 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
6125 by doing lineno substitution only on lines containing "$LINENO".
6127 2004-01-04 Paul Eggert <eggert@twinsun.com>
6129 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6130 Use "rm -f" to remove conftest.sed, not plain "rm".
6131 Bug reported by David Relson in
6132 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6134 * Makefile.am (autom4te-update):
6135 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6136 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6137 * doc/autoconf.texi (Guidelines): Likewise.
6138 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

6143 * tests/Makefile.am (clean-local): Likewise.
6144 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
6145 srcdir): Likewise.
6146 * doc/autoconf.texi (Limitations of Usual Tools):
6147 Warn against "rm -fr".
6149 2004-01-03 Paul Eggert <eggert@twinsun.com>
6151 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6152 -c -o might not work. From a suggestion by Kevin Ryde.
6153 (C Compiler, Generating Sources, Limitations
6154 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6155 Don't put '-o' after non-options, as POSIX doesn't allow this.
6156 Mention that cc's name might be gcc or c89 or whatever.
6158 2004-01-04 Kevin Ryde <user42@zip.com.au>
6160 * doc/autoconf.texi: Add various further index entries.
6162 2003-12-29 Paul Eggert <eggert@twinsun.com>
6164 * bin/autoreconf.in (autoreconf_current_directory):
6165 Fix typo: mkdir without umask arg.
6167 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6169 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6170 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6171 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6172 explanation clearer.
6174 2003-12-24 Andreas Schwab <schwab@suse.de>
6176 * doc/autoconf.texi (Default Includes): Fix misspelling of
6177 AC_INCLUDES_DEFAULT.
6179 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
6181 * configure.ac: Test if sh -n works.
6182 * configure: Regenerate.
6183 * tests/atlocal.in: Store the result here.
6184 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
6185 tools.at, looking in atlocal's ac_cv_sh_n_works instead
6186 of explicitly testing.
6187 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
6188 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
6189 * tests/tools.at (Syntax of the shell scripts): Simplify
6190 using AT_CHECK_SHELL_SYNTAX.
6191 (Syntax of the Perl scripts): Remove definition of
6192 AT_CHECK_PERL_SYNTAX.
6194 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
6196 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
6197 stderr to /dev/null.
6198 * bin/autoconf.in: Regenerate.
6199 * bin/wrapper.in: Regenerate.

6203 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
6204 Extracted from AS_SHELL_SANITIZE.
6205 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
6206 macros.
6207 (AS_SHELL_SANITIZE): Move reinvocation code from
6208 _AS_LINENO_WORKS, use it to find out if shell
6209 functions work.
6210 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
6211 does not work.
6212 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
6213 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN
6214 was called.

6223 * config/announce-gen (&print_locations, &print_signatures)
6224 (&sizes): New.
6225 Use them.

6227 them on the fly.
6229 2003-11-24 Akim Demaille <akim@epita.fr>
6231 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

6259 parameter of AU_DEFUN.
6260 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.

6264 the expanded body, consistently with other macros such as AC_USG.
6266 2003-11-17 Paul Eggert <eggert@twinsun.com>
6268 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
6269 into the initial confdefs.h, to work around a bug in NextStep 3.3
6270 patch 3 reported by Eric Sunshine.
6272 2003-11-15 Kevin Ryde <user42@zip.com.au>
6274 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
6275 than $target since the latter is not usual, add guidelines on when to
6276 use or not use the system type.
6278 2003-11-12 Derek Price <derek@ximbiot.com>
6280 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
6281 typo misrepaired by an auto-spellcheck.
6283 2003-11-12 Akim Demaille <akim@epita.fr>
6285 * bin/autoreconf.in (&parse_args): Don't call automake with
6286 --force-missing unless it actually supports it.
6287 From Debian #219336.
6289 2003-11-12 Akim Demaille <akim@epita.fr>
6291 * configure.ac: Bump to 2.59a.

6300 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE
6301 so that ac_abs_builddir, ac_abs_top_builddir, ac_abs_srcdir,

6309 2003-11-05 Kevin Ryde <user42@zip.com.au>

6453 Problems reported by Eric Sunshine.
6455 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
6457 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
6458 -mGLOB_options_string stuff for Intel ifc, which can cause

6482 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6483 cache variable instead of $G77 to decide whether to include -O2,
6484 since $G77 is specific to Fortran 77.

6488 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
6489 free" flag. Re-order flags tested into rough order of popularity.
6491 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6493 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
6494 arguments so that it can be used with syntax identical to
6495 AC_PROG_F77, and so that we can more easily decide to
6496 remove/deprecate the DIALECT optional argument in the future if it
6497 proves troublesome.
6498 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
6499 non-freeform-supporting compilers. Document freeform flags.
6501 2003-10-03 Akim Demaille <akim@epita.fr>

6513 2003-10-03 Akim Demaille <akim@epita.fr>
6515 * configure.ac: Quotation and formatting changes.

6563 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
6564 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
6565 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
6566 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
6568 2003-09-26 Akim Demaille <akim@epita.fr>
6570 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6571 directory for AC_CONFIG_COMMANDS' first argument exists.
6572 This makes valid the invocation of _AC_SRCPATH that follows.
6573 Reported by Eric Sunshine.
6574 * doc/autoconf.texi (Configuration Commands): Adjust.
6576 2003-09-26 Akim Demaille <akim@epita.fr>
6578 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6579 Reported by Ralf Corsepius.

6583 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6584 arguments.
6585 Actually, use AU_ALIAS.
6586 From Bruno Haible.

6595 2003-09-26 Akim Demaille <akim@epita.fr>
6597 The test suite are sometimes assigning timings incorrectly.
6598 Reported by Henk Krus.
6599 Diagnosed by Nicolas Joly.
6601 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6602 AT_help_all.
6603 Instead of making AT_help a sequence of assignments to grow
6604 $at_help_all, just make AT_help_all be the growing contents of
6605 $at_help_all, and make a single assignment in...
6606 (AT_INIT): here.
6607 (at_times_skip): Flip the meaning and rename as...
6608 (at_times_p): this.
6609 (AT_INIT): When summarizing the test that ran, remove
6610 $at_times_file after use, and check it is present before trying to
6611 use it.
6613 2003-09-25 Akim Demaille <akim@epita.fr>
6615 Version 2.57d.
6617 * bin/Makefile.am (edit): Handle '@configure_input@'.

6619 (ifnames): chmod -w.
6620 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6621 executables, not bin/ executables! Otherwise all the magic needed
6622 to find non installed files is turned off. This caused a failure
6623 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6624 as found in its environment (sent by tests/autoreconf): pointing
6625 to bin/autom4te that could not find its files.
6626 * tests/mktests.sh: Force the replacement of generated files, for
6627 the sake of "mv" program that are interactive when overwriting a
6628 -w file.
6629 * config/install-sh: Upgrade from CVS Automake.
6631 2003-09-23 Paul Eggert <eggert@twinsun.com>

6634 versus test -L issues.
6636 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
6637 Paul Eggert <eggert@twinsun.com>
6639 Trivial change to support GCC's configuration procedure.
6640 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
6641 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
6642 about inconsistency if the preprocessor is set to give errors for
6643 any warning.
6644 * doc/autoconf.texi (C Compiler Characteristics): Document this.
6646 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
6648 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
6649 and XFile.pm from Automake.

6662 2003-09-12 Akim Demaille <akim@epita.fr>
6664 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
6665 not asm/types.h.
6667 2003-09-11 Akim Demaille <akim@epita.fr>
6669 * doc/autoconf.texi (Header Portability): linux/random.h.
6670 From Peter Hendrickson.
6672 2003-09-10 Akim Demaille <akim@epita.fr>
6674 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
6675 willing to edit the output files.
6677 2003-09-10 Akim Demaille <akim@epita.fr>
6679 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
6680 and AC_FC_FREEFORM.
6681 * tests/mktests.sh: Skip AC_FC_SRCEXT.
6682 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
6684 2003-09-09 Akim Demaille <akim@epita.fr>

6697 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
6698 Improve the accuracy of the wording about obsolescence.
6699 From a suggestion by Ian Lance Taylor in
6700 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
6702 2003-09-05 Paul Eggert <eggert@twinsun.com>
6704 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
6705 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
6707 2003-09-04 Akim Demaille <akim@epita.fr>
6709 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
6710 AC_FUNC_WAIT3.
6712 2003-09-04 Akim Demaille <akim@epita.fr>
6714 * bin/autom4te.in: Use &fatal where more appropriate than &error.
6715 (freeze): When exiting, use $exit_code.
6716 * lib/autoconf/fortran.m4: Comment changes.
6718 2003-09-04 Akim Demaille <akim@epita.fr>
6720 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
6722 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
6724 Add support for newer Fortran dialects. The F77 interface is
6725 unchanged, and continues to support Fortran 77. New FC macros
6726 correspond to all the old F77 macros, with output variables FC,
6727 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
6728 available dialect, but older dialects can be specified. There are
6729 new macros AC_FC_SRCEXT to set the source extension, and
6730 AC_FC_FREEFORM to accept free-form source files.
6732 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
6733 New macros.
6734 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
6735 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
6736 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),

6746 AC_FC_SRCEXT, AC_FC_FREEFORM):
6747 New macros.
6748 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
6749 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
6750 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
6751 Rewrite in terms of the above.
6752 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
6753 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

6755 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
6757 2003-09-02 Paul Eggert <eggert@twinsun.com>
6759 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
6760 Document problems with timestamp resolution that 'make', 'cp -p', and
6761 'touch -r' have.
6763 2003-08-27 Akim Demaille <akim@epita.fr>
6765 * tests/m4sugar.at (cross_warning): Make sure to enable the
6766 output, so that we can track spurious m4sugar output.
6767 * tests/local.at: Require 2.57.
6768 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
6769 are defaulted by AT_CHECK anyway.
6770 Use AT_CHECK_AUTOM4TE.
6771 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
6772 missing dnl.
6774 2003-08-27 Akim Demaille <akim@epita.fr>
6776 * bin/autoheader.in: Issue the "Using auxiliary..." message only
6777 when -Wobsolete is set.
6778 Set it on by default.
6779 Suggested by Klee Dienes.

6790 after AC_OUTPUT.
6792 2003-08-25 Akim Demaille <akim@epita.fr>
6794 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
6795 CVS Bison.
6797 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
6799 * bin/autoreconf.in (parse_args): Do not pass --no-force to

6811 2003-08-22 Akim Demaille <akim@epita.fr>
6813 Version 2.57b.
6815 * Makefile.cfg (local-checks-to-skip): New.
6816 * Makefile.maint (local-check): Rename as...
6817 (local-checks-available): this.
6818 (local-check): New.
6820 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
6821 * configure.ac: Require Automake 1.7.6.
6823 2003-08-22 Akim Demaille <akim@epita.fr>
6825 Output stack traces in warnings.
6827 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
6828 Replace the former...
6829 (m4_warn): Pass the call stack to _m4_warn.
6830 * bin/autom4te.in: Adjust to output the call stack.
6831 * tests/m4sugar.at (m4@&t@_warn): Adjust.
6833 2003-08-22 Akim Demaille <akim@epita.fr>
6835 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
6836 * bin/autom4te.in: Adjust.
6838 2003-08-21 Akim Demaille <akim@epita.fr>
6840 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
6841 (&verbose): Remove.
6842 (&getopt): Adjust the note and verb channels, depending upon
6843 --verbose.
6844 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
6845 * bin/autoupdate.in: Adjust.
6846 Use &verb, not &verbose.
6848 2003-08-21 Akim Demaille <akim@epita.fr>
6850 * bin/autoheader.in (&parse_args): Use &parse_warnings and
6851 &parse_WARNINGS.
6852 ($help): Use Autom4te::ChannelDefs::usage.
6853 * bin/autoscan.in: Use Autom4te::ChannelDefs.
6854 * lib/Autom4te/General.pm: Don't export error: you don't own it.
6856 2003-08-21 Akim Demaille <akim@epita.fr>
6858 First stab at preserving warnings between calls to autom4te,
6859 including when the cache is used.
6861 There are still several issues: (i) there are too many runs of m4
6862 (one for include, one for warnings, and some more), (ii) warnings
6863 spreading on several lines are not handled gracefully, (iii) the
6864 code meant to have the call stack display for errors does not work
6865 (its handling should move from m4 to autom4te).
6867 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
6868 Use them.
6869 (@preselect): Add m4_warn.
6870 ($exit_status): Remove, use $exit_code.
6871 ($help): Use Autom4te::ChannelDefs::usage.
6872 (&handle_m4): No longer define the m4_warnings.
6873 At each run, extract and report the warnings.
6874 Always cache the result, including if the exit status is on
6875 failure, since if nothing changes, we should result in the same
6876 failure, hence we can use the cache.
6877 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
6878 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
6879 Remove.
6880 (m4_warn): Redefine as a do-nothing: it is its invocation that
6881 matters, as warnings are now reported via traces.
6882 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
6883 the contents of m4_warn: make it _call_ m4_warn, so that tracing
6884 the latter reveals calls to the former.
6886 Adjust the tests.
6888 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
6890 2003-08-21 Akim Demaille <akim@epita.fr>
6892 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
6893 Use them.
6895 2003-08-21 Akim Demaille <akim@epita.fr>
6897 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
6898 forward order.
6899 * lib/Autom4te/ChannelDefs.pm: Doc typos.
6900 (&parse_warnings): Accept a list of warning requests.
6901 (&usage): Return a string, not a side effect.
6902 (cross): New warning category.
6904 2003-08-21 Akim Demaille <akim@epita.fr>
6906 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
6907 (&require_configure_ac): Accept an optional directory argument.
6908 ($configure_ac): Remove.
6909 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
6910 (&catfile): Remove.
6911 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
6912 * bin/autoscan.in: Adjust.
6914 2003-08-20 Akim Demaille <akim@epita.fr>
6916 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
6917 Reported by Alexandre Duret-Lutz.
6919 2003-08-20 Akim Demaille <akim@epita.fr>
6921 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
6922 * bin/autom4te: Adjust.
6923 In particular, be Autoconf tools are really silent when properly
6924 working, bind the verbosity of the 'note' channel to $verbose.
6925 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
6926 (&xsystem, &contents): Remove, since they are exported by...
6927 * lib/Autom4te/FileUtils.pm: this.
6928 More perldoc.
6929 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
6930 * lib/Autom4te/FileUtils.pm: here.
6932 2003-08-20 Akim Demaille <akim@epita.fr>
6934 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
6935 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
6936 from CVS Automake.
6938 2003-08-20 Akim Demaille <akim@epita.fr>
6940 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
6941 (autom4te-update): New.
6942 * Makefile.cfg (update): Bind autom4te-update.
6944 2003-08-19 Derek Price <derek@ximbiot.com>
6946 * lib/autotest/general.m4: Comment various HELP_* diversions.
6947 (PARSE_ARGS_BEGIN): New section for option parsing related

6956 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
6958 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
6960 * lib/autom4te.in (Automake-preselections): Preselect
6961 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
6962 and m4_sinclude.
6964 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
6966 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
6967 (Autoconf-without-aclocal-m4): ... this new language.
6968 * doc/autoconf.texi (autom4te Invocation): Mention
6969 Autoconf-without-aclocal-m4.

6974 RUN-IF-PASS optional arguments.

6985 2003-08-14 Derek Price <derek@ximbiot.com>
6987 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
6988 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
6989 shorter column three. Add DESCRIPTION to log file content.
6991 2003-08-13 Derek Price <derek@ximbiot.com>
6993 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
6994 output.
6996 2003-08-12 Derek Price <derek@ximbiot.com>
6998 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
6999 (AT_CHECK_NOESCAPE): Move core functionality to...
7000 (_AT_CHECK): ...this new macro.
7002 2003-08-07 Derek Price <derek@ximbiot.com>
7004 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
7005 (AT_CHECK_NOESCAPE): ...to this new macro.
7007 2003-07-31 Paul Eggert <eggert@twinsun.com>
7009 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
7010 in Bash 2.01. Problem reported by Brian Gough in
7011 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
7013 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
7015 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
7016 -lcrt1.o, for OS X. (trivial change)
7018 2003-07-07 Paul Eggert <eggert@twinsun.com>
7020 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
7021 inside '#ifndef __cplusplus'. Problem reported by
7022 Bob Friesenhahn.
7024 2003-07-06 Bill Clarke <llib@computer.org>
7026 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7027 'long', not 'int', for benefit of Sun's recent C++ compilers
7028 (trivial change). See:
7029 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
7030 (This really should be 'intptr_t', not 'long', but that would
7031 take more work.)
7033 2003-06-25 Akim Demaille <akim@epita.fr>
7035 * lib/Makefile.am (autom4te.cfg): Make it read only.
7036 Depend on Makefile since it contains substitutions.
7037 From Paolo Bonzini.
7038 * lib/autom4te.in (args): Add local.at? for Autotest args.
7039 This change was made on autom4te.cfg which is generated.
7040 Reported by Raja R. Harinath.
7042 2003-06-25 Akim Demaille <akim@epita.fr>
7044 * doc/autoconf.texi (Header Portability): sys/mount.h.
7045 From Gareth McCaughan.
7047 2003-06-23 Akim Demaille <akim@epita.fr>
7049 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7050 not all of them. This fixes 1. the fact that when testing
7051 Autoconf there are many many config.log, 2. the incorrect use of
7052 top_srcdir to find config.log.
7053 Don't mix the detailed output of failed test with the summary of
7054 failures. Rather, append detailed log afterwards.
7056 2003-06-23 Akim Demaille <akim@epita.fr>
7058 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7059 always run: output config.log on $at_group_log.
7061 2003-06-23 Akim Demaille <akim@epita.fr>
7063 * tests/torture.at (#define header templates): Don't use quotes in
7064 C++ comments as it puzzles Emacs' sh font-lock-mode.
7066 2003-06-23 Akim Demaille <akim@epita.fr>
7068 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.

7077 2003-06-21 Kevin Ryde <user42@zip.com.au>
7079 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
7080 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
7081 ensuring we add -std1 for full-ANSI.
7083 * doc/autoconf.texi (hdrindex): New macro.
7084 Add index entries for portability of various standard header files.
7086 2003-06-20 Akim Demaille <akim@epita.fr>

7113 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7114 (TEST_SCRIPT): New diversion.
7115 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7116 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7117 (AT_INIT): Support for expected failures.
7119 2003-06-02 Akim Demaille <akim@epita.fr>
7121 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7122 changes.
7123 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7124 Autoconf nor Automake.
7125 (&contents): New, from Automake.
7126 PODify.
7128 2003-05-28 Paul Eggert <eggert@twinsun.com>
7130 * NEWS, doc/autoconf.texi (Particular Functions),
7131 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7132 is the inverse of localtime.
7134 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7136 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7137 (handle_exec_errors): New function. Work around $! being
7138 altered by WEXITSTATUS.
7139 (xqx, xsystem): Use handle_exec_errors.
7141 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7143 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7144 Do not call `_exit()', simply modify `$?'.
7145 (xsystem): Reset $! before running system, and check it afterward.
7146 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7147 63 for version mismatches.
7149 2003-05-23 Akim Demaille <akim@epita.fr>
7151 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7152 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7153 the middle of a line).
7154 * lib/m4sugar/m4sugar.m4: Likewise.
7155 Remove useless spaces in comments.
7157 2003-05-23 Akim Demaille <akim@epita.fr>
7159 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7160 exit 63, so that we (or Automake's "missing") can tell the
7161 difference with a plain failure.
7162 * doc/autoconf.texi (Notices): Adjust.
7164 2003-05-23 Akim Demaille <akim@epita.fr>
7166 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7167 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7168 White spaces cleanup.
7170 2003-05-22 Jim Meyering <jim@meyering.net>
7171 Paul Eggert <eggert@twinsun.com>
7173 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7174 Remove `#include <stdlib.h>' from the list; we should never
7175 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7176 resulting namespace pollution would cause other tests to fail.
7177 Configure scripts run with some older versions of g++ and HP's
7178 aCC would fail due to such an #include. Problems reported by
7179 Matthew Mueller in <http://bugs.debian.org/120704> and by
7180 Keith Bostic in
7181 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7182 In the test, use the test declaration before including <stdlib.h>,
7183 as that's closer to how it'll be used.
7185 2003-05-23 Akim Demaille <akim@epita.fr>
7187 * doc/autoconf.texi (Header Portability): ucred.h.
7188 From Ian Redfern.
7190 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7192 Overhaul Autotest's logging: generate separate log files
7193 in testsuite.dir/NNN/testsuite.log, and append them to
7194 testsuite.log instead of re-running the test verbosely.
7196 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7197 file descriptor, write 0 to at_status_file instead of setting
7198 at_status=0, initialize some new variables (at_status_file,
7199 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7200 to rerun the tests, instead append the at_group_log to the
7201 at_suite_log when a test fails.
7202 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7203 with the AS_MESSAGE_LOG_FD redirected to stdout.
7204 (AT_CLEANUP): save the output status in $at_status_file
7205 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7206 its original place.
7207 (AT_CHECK): since tests are run with a redirected stdout,
7208 and used to be re-run in verbose mode, turn some $at_verbose
7209 into echo, and don't redirect the output of testing stdout
7210 and stderr.
7212 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7213 the name of the debugging directory and information about
7214 its contents.
7216 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7218 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd

7303 user name space clashes.
7304 Reported by Bruno Haible.
7306 2003-05-16 Akim Demaille <akim@epita.fr>

7331 and truncate.
7333 2003-05-06 Akim Demaille <akim@epita.fr>
7335 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7336 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7337 by aclocal.m4 is changed it might require the importing of another
7338 m4 extension file, i.e., aclocal must be run.
7340 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7341 (&parse_args): Use --force with aclocal if required and supported.
7342 (&autoreconf_current_directory): Use &run_aclocal.
7344 2003-05-06 Akim Demaille <akim@epita.fr>
7346 Lock autom4te's cache.
7348 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
7349 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7350 argument instead of a file name, so that the request file remains
7351 open during the whole autom4te run.
7352 ($icache_file): New.
7353 (&freeze): Lock the $icache_file.
7355 2003-04-29 Derek Price <derek@ximbiot.com>
7357 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7358 seperator with m4_append_uniq(). It doesn't work.
7359 (AT_CLEANUP): Add `;' to end of at_help_all.
7360 (AT_INIT): Allow --keywords to be specified more than once. When
7361 grepping $at_help_all for keywords, use the field and keyword
7362 seperators to ensure a complete keyword match. Alter at_prev handling
7363 to support the new --keywords behavior.
7365 2003-04-27 Karl Berry <karl@freefriends.org>
7367 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7368 align better with others. I also made some of the individual
7369 entries on one line, for brevity and to make it easier for me to
7370 sort my dir-example file in the Texinfo distribution :).
7372 2003-04-12 Jim Meyering <jim@meyering.net>

7387 * GNUmakefile (SHELL): Don't assume sh is in /bin/.
7388 From Ilya Zakharevich.
7390 2003-04-08 Akim Demaille <akim@epita.fr>
7392 * doc/autoconf.texi (Particular Headers): Some about sys/socket.h,
7393 net/if.h, stdlib.h.

7412 * doc/Makefile.am (CLEANFILES): Adjust.
7413 (TEXI2DVI): Make it --batch.
7415 2003-03-31 Derek Price <derek@ximbiot.com>
7417 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
7418 which removed the main loop.
7419 Thanks to Akim Demaille.
7421 2003-03-29 Akim Demaille <akim@epita.fr>

7437 header causes problems.
7439 2003-03-28 Akim Demaille <akim@epita.fr>
7441 * tests/torture.at (Configuring subdirectories): Require aclocal
7442 1.4, otherwise the test fails, as it does support configure.ac.
7443 This fixes the "test 40 failed" bug reports.
7445 2003-03-28 Akim Demaille <akim@epita.fr>
7447 * doc/autoconf.texi (C Compiler): `#line' portability.
7448 From Paul Eggert and Nelson H. F. Beebe.
7450 2003-03-27 Derek Price <derek@ximbiot.com>
7452 * lib/autotest/general.m4: Eliminate main loop and reorganize test
7453 layout in order to allow scripting around test groups.
7455 2003-03-27 Derek Price <derek@ximbiot.com>
7457 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
7458 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
7459 use new diversions in preparation for accepting new arguments and

7465 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
7466 obsolete AC_HELP_STRING.
7467 (AC_HELP_STRING): AU_DEFUN to...
7468 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
7469 * tests/m4sh.at (AS_HELP_STRING): New test.
7471 * tests/acgeneral.at: Regenerated.
7473 2003-03-26 Derek Price <derek@ximbiot.com>
7475 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
7476 sense. Verbosify the diversion definitions comment.
7478 2003-03-26 Derek Price <derek@ximbiot.com>
7480 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to
7481 AS_PREPARE.

7515 Tru64 make in the "target lookup" section.
7516 (Automake): Automake 1.5+ no longer requires special tools to be
7517 present on the developer's host.

7525 * bin/autom4te.in (BEGIN): Likewise.
7526 * bin/autoreconf.in (BEGIN): Likewise.
7527 * bin/autoscan.in (BEGIN): Likewise.
7528 * bin/autoupdate.in (BEGIN): Likewise.

7533 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
7534 to cope with DOS-style absolute paths, when constructing
7535 ${ac_make}.
7537 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
7538 When constructing paths with IFS=:, quote the path. If we're
7539 constructing a DOS-style absolute path, we don't want to split it
7540 on the colon.
7542 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
7543 in description.
7545 2003-02-25 Pavel Roskin <proski@gnu.org>

7553 2002-09-01 patch by replacing "test -n" with "test -z".
7554 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
7555 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
7557 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
7558 to fix a mismatch between example and discussion.
7560 2003-02-24 Kevin Ryde <user42@zip.com.au>
7562 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
7563 format starting with "-".
7565 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7567 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
7568 is not portable inside Makefile.
7570 2003-02-20 Akim Demaille <akim@epita.fr>
7572 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
7573 compiler says yeah, but preproc says nope, compiler is right.
7574 Conversely, prompt the reader to send a bug report to the
7575 maintainers of the package, not of Autoconf.
7577 2003-02-20 Klee Dienes <kdienes@apple.com>
7579 * bin/autoreconf.in (autoreconf_current_directory): Properly
7580 handle an empty aclocal.m4.

7586 From Larry Jones.
7588 2002-12-23 Paul Eggert <eggert@twinsun.com>
7590 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7591 innocuous variant befor including <limits.h> or <assert.h>. This
7592 works around a bug reported by Albert Chin: HP-UX 11i
7593 (and earlier versions) have a <limits.h> that declares
7594 gettimeofday and many other functions.
7596 2002-12-03 Paul Eggert <eggert@twinsun.com>
7598 Version 2.57.
7600 * NEWS, configure.ac: Update version.
7602 * doc/fdl.texi: Upgrade to FDL version 1.2.
7604 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7605 nontrivially in main's body, so that f's external declaration is
7606 not optimized away in AIX. This should fix the bug reported by
7607 Martin Frydl in
7608 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7610 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7611 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7612 defined, to support freestanding compilers. This should fix the
7613 bug reported by Momchil Velkov in
7614 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7616 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
7617 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
7618 obsolete AC_CHECK_TYPE. The missing empty arg was reported
7619 by Simon Josefsson in

7622 * Makefile.maint (www-gnu): New macro.
7623 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
7624 the location has moved.
7626 2002-12-02 Martin Frydl <martin@systinet.com>
7628 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
7629 \(.*\) match is too long and there is something more to be checked.
7630 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
7632 2002-11-15 Akim Demaille <akim@epita.fr>
7634 Version 2.56.
7636 * config/install-sh: chmod +x.
7637 From Paul Eggert.
7638 * config/move-if-change: Indenting changes.
7639 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
7640 * configure.ac (AM_INIT_AUTOMAKE): here.
7641 Require 1.7.1.
7643 2002-11-14 Akim Demaille <akim@epita.fr>
7645 Version 2.55.
7647 * config/config.guess, config/config.sub, config/install-sh:
7648 Update from masters.
7650 2002-11-14 Akim Demaille <akim@epita.fr>
7652 * Makefile.maint: Sync with Bison, i.e.:
7653 (po-check): Scan .l and .y files instead of the
7654 .c and the .h files that they generate. This fixes the bug
7655 reported by Tim Van Holder in:
7656 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7657 Look for N_ as well as for _. Try to avoid matching #define for
7658 N_ and _.
7659 From Paul Eggert.
7661 2002-11-14 Akim Demaille <akim@epita.fr>
7663 * doc/autoconf.texi (C Compiler): Compiling several files at once.
7664 From Paul Eggert and Albert Chin-A-Young.
7666 2002-11-14 Akim Demaille <akim@epita.fr>
7668 * doc/autoconf.texi (C Compiler): Solitary backslashes.
7669 From Paul Eggert and Albert Chin-A-Young.
7671 2002-11-14 Kevin Ryde <user42@zip.com.au>
7673 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
7674 than assigning in main, to avoid HP cc +O3 optimizing it away.
7676 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
7678 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
7679 option. Process --recheck after parsing all options. Pass -q
7680 option to configure on --recheck.
7681 (AC_OUTPUT): Pass -q from configure to config.status.
7682 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
7683 arguments to record.
7684 * doc/autoconf.texi (config.status Invocation): Document
7685 config.status -q option.
7687 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
7689 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
7690 Makefile.in if Makefile.am exists.
7691 (output): Strip `.am' from Makefiles. Don't
7692 output AC_CONFIG_FILES if no Makefiles were found.
7694 2002-11-07 Akim Demaille <akim@epita.fr>
7696 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
7697 (local_updates): New.
7698 * Makefile.maint: Update, from CVS Bison.
7699 (local_updates): New.
7701 2002-11-06 Akim Demaille <akim@epita.fr>
7703 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
7704 declaration in extern "C" too.
7705 Reported by Roberto Bagnara.
7707 2002-11-06 Akim Demaille <akim@epita.fr>
7709 * tests/torture.at (Configuring subdirectories): Don't use grep
7710 -w.
7711 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
7712 Reported by Ezra Peisach.
7714 2002-11-05 Akim Demaille <akim@epita.fr>
7716 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
7717 Remove.
7718 We _have_ to stop using the old compatibility scheme that tried to
7719 avoid useless backslashes because Libtool 1.4.3 contains a
7720 AC_DEFINE([error_t], [int],
7721 [Define to a type to use for \`error_t' if it is not
7722 otherwise available.])
7723 We _have_ to quote the single quote and backslashes with \. The
7724 old compatibility scheme saw that ` was backslashed, and therefore
7725 did not quote the single quote. Hence before this patch, Autoconf
7726 was not compatible with Libtool.
7728 2002-11-04 Paul Eggert <eggert@twinsun.com>
7730 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
7731 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
7732 LC_NAME, LC_PAPER, LC_TELEPHONE.
7733 * doc/autoconf.texi (Special Shell Variables): Mention those vars.
7735 2002-11-04 Akim Demaille <akim@epita.fr>
7737 Version 2.54c.
7739 * Makefile.maint (update, cvs-update, po-update, do-po-update):
7740 New.
7741 * config/texinfo.tex: Update.
7743 2002-11-03 Akim Demaille <akim@epita.fr>
7745 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
7746 from...
7747 (&autoreconf): here.
7748 ($help, $make, &parse_args, &autoreconf_current_directory):
7749 Support -m/--make.
7750 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7752 2002-10-31 Bruno Haible <bruno@clisp.org>
7754 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.
7755 Change name of cache variable to ac_cv_func_malloc_0_nonnull.

7758 to ac_cv_func_realloc_0_nonnull.
7759 (AC_FUNC_REALLOC): Change description of HAVE_REALLOC macro.
7761 2002-10-31 Akim Demaille <akim@epita.fr>
7763 The test suite was no longer checking for trailing envvars and files.
7765 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
7766 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
7768 2002-10-31 Akim Demaille <akim@epita.fr>
7770 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display

7824 * tests/torture.at (Deep Package): New test.

8058 2002-10-22 Akim Demaille <akim@epita.fr>
8060 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

8064 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
8065 strings.
8067 2002-10-22 Akim Demaille <akim@epita.fr>
8069 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

8116 longer required can still cause errors.
8117 Reported by Alexandre Duret-Lutz.
8119 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
8120 to frozen files in @ARGV, as @ARGV must remain being a list of

8122 (&files_to_options): New function.
8123 (&freeze): Use &error.
8124 (&up_to_date): If a file that was included according to the cache
8125 is no longer there, then the output is out dated.
8126 (&main): Don't even check whether a file is up to date is anyway
8127 --force is given.
8128 * tests/tools.at (autom4te cache): New.
8130 2002-10-16 Akim Demaille <akim@epita.fr>

8135 Factor some code.
8136 (&autoreconf): Report the directories we enter *and leave*, so
8137 that error messages can be easily located, and use GNU Make
8138 format, so that Emacs' compile mode understands us.
8139 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8140 if some file was changed instead of `print'.
8141 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

8175 file name to enable parallel executions.
8176 From Sam Varshavchik.
8178 2002-10-08 Akim Demaille <akim@epita.fr>
8180 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8181 aclocal invocation, as Gettext macros might not be visible to
8182 aclocal.
8183 Instead of blindly running autopoint, scan configure.ac (not the
8184 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8185 Reported by Paul D. Smith.
8187 2002-10-08 Paul Eggert <eggert@twinsun.com>
8189 Work around problems found when POSIXLY_CORRECT=1 is set.
8190 None of this seems to have anything to do with POSIX, really,
8191 but it's how Perl getopt works.
8192 * bin/autom4te.in (parse_args): Configure GetOpt with
8193 "permute", too.
8194 * doc/autoconf.texi (Invoking autom4te):
8195 --warning -> --warnings.

8217 * tests/torture.at (Configuring subdirectories): Be robust to
8218 users who use config.site to require for a cache: in this case,
8219 the two last configure runs, using two different sets of
8220 arguments, trigger a legitimate error.
8222 2002-09-28 Akim Demaille <akim@epita.fr>
8224 * tests/m4sh.at (Functions Support, Functions and return Support):
8225 New.

8238 (tm_zone): Move their rules to...
8239 * lib/autoconf/types.m4: here, using AN_ macros.
8240 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
8241 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
8242 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
8243 * lib/autoconf/programs.m4: here.

8255 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
8256 (.m4.m4f): Don't pass --prepend-include, since that's done by
8257 tests/autom4te itself.

8259 (autoscan.list): New target --this file is no longer a source.
8260 (autoscan.pre): New file.
8262 2002-09-28 Akim Demaille <akim@epita.fr>
8264 * bin/autoscan.in (@kinds): Make them singular.
8265 Adjust all uses.
8266 (&init_tables): When --debug, report the list of rules to ease
8267 tracking changes in autoscan.list.
8268 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8270 2002-09-28 Akim Demaille <akim@epita.fr>
8272 * lib/autoscan/functions, lib/autoscan/headers,
8273 * lib/autoscan/identifiers, lib/autoscan/makevars,

8276 * bin/autoscan.in (&init_tables): Adjust.
8278 2002-09-28 Akim Demaille <akim@epita.fr>
8280 * lib/autoscan/functions, lib/autoscan/headers,
8281 * lib/autoscan/identifiers, lib/autoscan/makevars,
8282 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
8283 `functions' line is now prefixed with `function:'.
8284 * bin/autoscan.in (&init_tables): Adjust.
8286 2002-09-28 Akim Demaille <akim@epita.fr>
8288 From now on, autoscan files must always map a macro name to a
8289 word: there is no `default' macro for autoscan.
8291 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8292 all.
8293 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8294 explicit.
8296 2002-09-28 Akim Demaille <akim@epita.fr>
8298 * bin/autoscan.in (%c_keywords): Remove.
8299 (&used): Keep only track of the words we might be interested in.
8300 (&output_kind): It is no longer needed to look for non active
8301 checks.
8303 2002-09-27 Akim Demaille <akim@epita.fr>
8305 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

8310 2002-09-27 Akim Demaille <akim@epita.fr>

8313 from /tmp.
8314 Thanks to Bill Moseley and Paul Eggert.
8315 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
8316 the tmpdir must be created.
8317 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
8318 dir be in the build tree, instead of $TMPDIR.
8320 2002-09-27 Akim Demaille <akim@epita.fr>
8322 * bin/autoscan.in: Improve the comments.
8323 (&parse_args): Drop obsolete undocumented options.
8324 (&output_kind): Output warnings.
8325 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

8331 Reported by Ralf Corsepius.
8332 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8334 2002-09-26 Akim Demaille <akim@epita.fr>
8336 Single suffix rules and seperated dependencies are not portable.
8338 * doc/autoconf.texi (Installation Directory Variables): Update.
8339 (Limitations of Make): Some about `Single Suffix Rules and
8340 Separated Dependencies'.
8341 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8342 (ifnames, autoscan, autom4te): Un-factor into several rules.
8344 2002-09-25 Paul Eggert <eggert@twinsun.com>
8346 * BUGS (Interoperability bugs): New section. Mention libtool
8347 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
8349 2002-09-24 Paul Eggert <eggert@twinsun.com>
8351 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
8352 make handles suffix-rules differently from GNU make.
8354 * bin/Makefile.am (SUFFIXES, .in): Remove.
8355 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
8356 Move the body of the old .in rule here.
8358 2002-09-16 Akim Demaille <akim@epita.fr>
8360 i960 compilers create `b.out' files by default.
8361 Reported by Ralf Corsepius.
8363 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
8364 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
8366 2002-09-13 Paul Eggert <eggert@twinsun.com>
8368 * doc/autoconf.texi (Particular Headers): Remove obsolete
8369 reference to `struct timezone' in the description of
8370 AC_HEADER_TIME.
8372 2002-09-13 Akim Demaille <akim@epita.fr>
8374 Version 2.54.
8376 * config/config.sub, config/config.guess: Update.
8377 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
8378 * Makefile.am: Adjust.
8380 2002-09-13 Akim Demaille <akim@epita.fr>
8382 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
8383 reading config.log when the compiler is rejected.
8384 Suggested by Guido Draheim.
8386 2002-09-13 Akim Demaille <akim@epita.fr>
8388 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8389 (chdir_init) might hang when stat'ing mounted directories.
8390 Reported by Vance Shipley.
8392 2002-09-12 Akim Demaille <akim@epita.fr>
8394 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8395 the lists.
8397 2002-09-12 Akim Demaille <akim@epita.fr>
8399 * doc/autoconf.texi (Defining Symbols): Present two different
8400 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
8401 difference between 1 argument calls, and 2-3 argument calls.
8403 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
8405 * doc/autoconf.texi: Review grammar and punctuation.
8407 2002-09-11 Paul Eggert <eggert@twinsun.com>
8409 * doc/autoconf.texi: Fix minor formatting, spelling, and
8410 grammatical typos.
8411 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8412 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8413 is obsolescent.
8415 2002-09-11 Akim Demaille <akim@epita.fr>
8417 * doc/autoconf.texi (Questions): Rename as...
8418 (FAQ): this.
8419 (Defining Directories): New.
8421 2002-09-09 Akim Demaille <akim@epita.fr>
8423 * doc/autoconf.texi (Making testsuite Scripts): Update.
8424 Suggested by Nishio Futoshi.
8426 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8428 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8429 plain `@' is wanted.
8431 2002-09-09 Akim Demaille <akim@epita.fr>
8433 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8434 `duplicates', since the algorithm was too naive and could keep
8435 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8436 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8437 Reported by Ralf Corsepius.
8438 * tests/torture.at (Configuring subdirectories): Exercise these
8439 cases.
8441 2002-09-09 Akim Demaille <akim@epita.fr>
8443 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
8444 looking for a replacement file.
8445 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8446 directory is relative.
8447 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8448 directory definition.
8449 Reported by Andreas Schwab and Jim Meyering.
8451 2002-09-06 Akim Demaille <akim@epita.fr>
8453 * doc/autoconf.texi (Setting Output Variables): Clarify what
8454 precious variables are.
8455 Suggested by Pontus Skoeld.
8457 2002-09-05 Akim Demaille <akim@epita.fr>
8459 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8460 (ifnames, autoscan, autom4te): Since we don't only depend on
8461 configure.ac variables (such as VERSION etc.), but also on prefix
8462 and so forth, depend on Makefile, not configure.ac.
8463 Reported by Alexandre Duret-Lutz.
8464 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8466 2002-09-05 Kevin Ryde <user42@zip.com.au>
8468 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8469 doesn't seem to be confined to ia64, just say "some versions".
8471 2002-09-04 Akim Demaille <akim@epita.fr>
8473 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8474 Automake 1.6c.
8475 * Makefile.am (maintainer-clean-local): Remove.
8476 (MAINTAINERCLEANFILES): Remove COPYING.
8478 2002-09-03 Paul Eggert <eggert@twinsun.com>
8480 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8481 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8482 Brinkmann.
8484 2002-09-03 Akim Demaille <akim@epita.fr>
8486 * configure.ac: Bump to 2.53d.
8487 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8488 as of today, on Automake's team suggestion.
8490 2002-09-03 Akim Demaille <akim@epita.fr>
8492 Version 2.53c.
8494 2002-09-02 Akim Demaille <akim@epita.fr>
8496 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8497 SITE_MACRO_DIR.
8498 * configure.ac: Disable SITE_MACRO_DIR.
8500 2002-09-02 Jim Meyering <meyering@lucent.com>
8502 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8503 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8504 Also, tweak grammar: s/make sure to/be sure to/.
8506 2002-09-02 Paul Eggert <eggert@twinsun.com>
8508 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8509 directory names are generally preferable to physical names.
8511 2002-09-02 Akim Demaille <akim@epita.fr>
8513 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8514 Reported by Raja R. Harinath.
8515 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8516 * bin/autoupdate.in: Use error instead of die.
8518 2002-09-01 Paul Eggert <eggert@twinsun.com>
8520 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8521 ordinary shell concatenation rather than echo+tr+sed command that
8522 runs afoul of a long-line-related sed bug in Solaris 8.
8524 * bin/autoheader.in (parse_args): --warning -> --warnings.
8526 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8527 stdout, as traditional "ls" does.
8528 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8529 _AC_COMPILER_EXEEXT_O): Likewise.
8530 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8532 * bin/autoconf.as: Add --prepend-include option. This patch was
8533 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8534 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8536 * bin/autoconf.in, configure: Regenerate.
8538 * doc/autoconf.texi (Special Shell Variables): Mention
8539 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8541 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8542 MAILPATH and set PS1, PS2, PS4 to default values, to work
8543 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8544 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8545 the Autoconf documentation specifies; fall back to "unset" only if
8546 this fails. Use a shell for-loop for this rather than an m4 loop,
8547 to shorten the output script.
8549 2002-08-30 Paul Eggert <eggert@twinsun.com>
8551 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8552 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8553 for the CDPATH problem. Document PWD.
8554 (Limitations of Builtins): Document the problem that "cd $foo" and
8555 "ls $foo" may refer to different directories in shells conforming
8556 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8557 example, since the old example is now out of date.
8559 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8560 FOO" and "ls FOO" talk about different directories; this catches
8561 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8562 spaghetti.
8564 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8565 of rolling our own unset.
8566 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8567 in practice we needn't worry about CDPATH if unset doesn't work.
8569 * Makefile.in, aclocal.m4, bin/Makefile.in,
8570 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8571 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8572 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8573 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8574 tests/Makefile.in: Regenerate with Automake 1.6.3.
8576 * config/config.guess, config/config.sub, config/mkinstalldirs:
8577 Update.
8579 * configure: Regenerate with self.
8581 2002-08-30 Kevin Ryde <user42@zip.com.au>
8583 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8584 default output.
8586 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8588 * bin/autom4te.in (Request::load): Correctly test for "do" read
8589 failure.
8591 2002-08-29 Akim Demaille <akim@epita.fr>
8593 * lib/Autom4te/General.pm (&xqx): New.
8594 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8595 hand, which is not portable.
8596 (&error): New.
8597 * bin/autom4te.in: Use them.
8598 Use &error instead of die.
8599 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8600 Adjust.
8602 2002-08-17 Paul Eggert <eggert@twinsun.com>
8604 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8605 default list of compilers to try, since it was long ago superseded
8606 by the ksh fc builtin. Suggested by Steven G. Johnson.
8608 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8610 * doc/autoconf.texi (Invoking autom4te): End the option table,
8611 fixing a bug introduced by the previous patch.
8612 (Limitations of Make): Add a 'target lookup' subentry in the
8613 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8615 2002-07-29 Mark D. Roth <roth@feep.net>
8617 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8618 options and use $AUTOM4TE_PATH.
8619 * doc/autoconf.texi: Remove documentation of autom4te
8620 --include-envvar and --site-macro-subdir options and document
8621 use of $AUTOM4TE_PATH.
8622 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8623 arguments from each language section.
8625 2002-07-29 Paul Eggert <eggert@twinsun.com>
8627 * doc/install.texi: Include copyright symbol in copyright notice.
8629 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8630 Replace with:
8631 (AM_MAKEINFOFLAGS): New macro.
8632 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8633 * Makefile.am (INSTALL): Use the new macros.
8634 Use -o rather than --output, since "missing" does not grok --output.
8636 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8638 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8639 comments do not always work. Never trust the exit status of
8640 `make -k'.
8642 2002-07-24 Kevin Ryde <user42@zip.com.au>
8644 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8645 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8647 2002-07-23 Paul Eggert <eggert@twinsun.com>
8649 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8650 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8651 apparently treats PATH="nonexistent" as if it contained ".".
8652 Bug reported by Stefan `Sec' Zehl.
8654 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8656 * doc/autoconf.texi (Limitations of Make): Mention the special
8657 handling of the obj/ directory by BSD make.
8659 2002-07-20 Kevin Ryde <user42@zip.com.au>
8661 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
8662 backslashes.
8664 2002-07-19 Akim Demaille <akim@epita.fr>
8666 * doc/autoconf.texi (Function Portability): `exit'.
8667 (Programming in M4sh): Ethymology of M4sh.
8669 2002-07-19 Akim Demaille <akim@epita.fr>
8671 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
8673 2002-07-18 Akim Demaille <akim@epita.fr>
8675 Version 2.53b.
8677 2002-07-18 Akim Demaille <akim@epita.fr>
8679 * config/config.guess, config/config.sub: Update.
8681 2002-07-18 Akim Demaille <akim@epita.fr>
8683 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
8684 Automake's parts.
8686 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
8687 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
8688 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
8690 2002-07-18 Akim Demaille <akim@epita.fr>,
8691 Alexandre Duret-Lutz <duret_g@epita.fr>
8693 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
8694 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
8696 2002-07-17 Russ Allbery <rra@stanford.edu>

8699 description of the tarname default.
8701 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
8703 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
8704 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
8705 latter was not run.
8707 2002-07-17 Akim Demaille <akim@epita.fr>
8709 * lib/Autom4te/General.pm (find_file): Browse the directories in
8710 the order they are given.
8712 2002-07-17 Akim Demaille <akim@epita.fr>
8714 * tests/wrapsh.as, tests/wrappl.as: Merge into...
8715 * tests/wrapper.as: this.
8716 * tests/Makefile.am, configure.ac: Adjust.
8718 2002-07-17 Mark D. Roth <roth@feep.net>
8720 * configure.ac: Add --enable-site-macro-dir option.
8721 * bin/Makefile.am: Expand @SITE_MACRO_DIR@.
8722 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
8723 --site-macro-subdir options.
8724 * bin/autoconf.in: Add --prepend-include option.
8725 * bin/autoheader.in: Add --prepend-include option.
8726 * bin/autoreconf.in: Add --prepend-include option.
8727 * bin/autoscan.in: Add --prepend-include option.
8728 * bin/autoupdate.in: Add --prepend-include option.
8729 * doc/autoconf.texi: Document use of $AC_MACRO_PATH and site
8730 macro directory, remove note that include path directories are
8731 used in reverse order, and document --prepend-include option.
8732 * lib/autom4te.in: Use --prepend-include instead of --include.
8733 * tests/wrapsh.in: Use --prepend-include instead of --include.
8735 2002-07-17 Akim Demaille <akim@epita.fr>
8737 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): `_' is allowed in
8738 tarnames.
8739 * doc/autoconf.texi (Initializing configure): Adjust.
8741 2002-07-17 Akim Demaille <akim@epita.fr>
8743 * lib/autoconf/functions.m4 (AC_FUNC_REALLOC, _AC_FUNC_REALLOC)
8744 (_AC_FUNC_MALLOC): New.

8778 2002-06-27 Paul Eggert <eggert@twinsun.com>
8780 * config/install-sh: Quote $src. Prefer || to test's -o option,
8781 as per "Limitations of Builtins".
8782 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
8783 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
8785 * tests/mktests.sh: Use grep instead of fgrep, as per
8786 "Limitations of Builtins".

8813 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>

8816 of the cache should not depend on the name under which autom4te
8817 was installed.
8819 2002-06-07 Akim Demaille <akim@epita.fr>

8825 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
8827 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
8828 _AC_LANG_PROGRAM_C_F77_HOOKS.

8843 2002-06-07 Akim Demaille <akim@epita.fr>
8845 * bin/autom4te.in (warn_forbidden): When rejecting a token,

8847 Suggested by Adam J. Richter.
8849 2002-06-07 Akim Demaille <akim@epita.fr>

8854 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

8912 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
8913 from the default list of compilers to try. Suggested by
8914 Kate Hedstrom.
8915 * NEWS: Document the above.
8916 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
8918 2002-05-17 Paul Eggert <eggert@twinsun.com>
8920 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
8921 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
8922 This improves on an earlier suggestion by H. Peter Anvin.
8924 2002-05-16 Paul Eggert <eggert@twinsun.com>
8926 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
8927 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
8928 Both macros now accept an optional source-dir arg.
8929 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
8931 * NEWS: Document this.
8932 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
8934 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
8935 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
8936 not for GNU extensions; this undoes part of the 2000-11-03 change,
8937 reverting to 2.13-compatible behavior.
8938 Add new optional argument DIR.
8939 (AC_FUNC_FNMATCH_GNU): New macro.
8941 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
8943 2002-05-08 Paul Eggert <eggert@twinsun.com>
8945 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
8946 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
8947 and it causes a 'test' syntax error if it fails.
8948 Bug reported by Stephen Gildea.
8950 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8951 If prototypes are supported, use them to check this at compile-time,
8952 instead of trying to check it at run-time. If we must do a run-time
8953 check, assume that setvbuf is standard when cross-compiling, as
8954 nonstandard setvbuf occurs only on ancient and unlikely hosts.
8955 Bug reported by Paul D. Smith.
8957 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
8958 argument specifying location of getloadavg.c. This removes a
8959 FIXME. This idea was taken from Jim Meyering's implementation in
8960 textutils.
8961 * doc/autoconf.texi (Particular Functions): Document this.
8962 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
8963 that's what the code does; this fixes a bug reported by
8964 Paul D. Smith.
8966 2002-05-03 Akim Demaille <akim@epita.fr>
8968 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
8969 autopoint instead of gettextize.
8970 ($uses_alocal): Rename as...
8971 ($uses_aclocal): this.
8972 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8973 Suggested by Bruno Haible.
8975 2002-05-03 Akim Demaille <akim@epita.fr>
8977 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
8979 2002-04-29 Paul Eggert <eggert@twinsun.com>
8981 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
8982 files to be 1 second older; just set them to be the same time.
8983 Also, sleep 1 second after the first aclocal, to work around
8984 problems with sub-second time stamps on the input files.
8986 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
8988 * doc/autoconf.texi: Mention "set -e -x" lossage
8989 under node "Limitations of Builtins".
8991 2002-04-29 Akim Demaille <akim@epita.fr>
8993 * doc/install.texi: Better wording for setting variables when
8994 running configure.
8995 From Christian Cornelssen.
8997 2002-04-29 Akim Demaille <akim@epita.fr>
8999 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9000 of lack of $LINENO support, then the test will compare the $LINENO
9001 in testsuite vs. the lineno in the test file. This is wrong, of
9002 course.
9003 Be sure to protect it.
9004 Reported by Patrick Welche.
9006 2002-04-25 Akim Demaille <akim@epita.fr>
9008 * doc/autoconf.texi (Obsolete Macros): Typo.
9009 Reported by Vladimir Volovich.
9011 2002-04-25 Akim Demaille <akim@epita.fr>
9013 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9014 than some of the input files, hence, on the second run of aclocal,
9015 if some of its input are younger, make them older.
9016 Suggested by Paul Eggert.
9018 2002-04-25 Akim Demaille <akim@epita.fr>
9020 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9021 Thanks to Paul Eggert.
9023 2002-04-25 Akim Demaille <akim@epita.fr>
9025 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9026 and ac_subst_vars be sh variables containing the list of
9027 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9028 DEFAULT diversion.
9029 (_AC_INIT_PREPARE): Use them to log them.
9030 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9031 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9032 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9033 _AC_SUBST_FILES and _AC_SUBST_VARS.
9034 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9036 2002-04-24 Akim Demaille <akim@epita.fr>
9038 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9039 autoheader, so that automake does not complain about a missing
9040 config.h.in that was to be created.
9042 2002-04-23 Akim Demaille <akim@epita.fr>
9044 * bin/autoheader.in (parse_args): --warning takes an argument.
9045 Fixes PR/220.

9096 * doc/autoconf.texi: Follow the outline suggested in the GNU
9097 Sample Texts sections of the Texinfo 4.2 manual. Most
9098 importantly, this makes sure that the copyright notices appear in
9099 all output formats. You probably need Texinfo 4.2 to generate
9100 the manual now.

9156 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

9205 Don't use the KILL diversion, as it kills spurious output, which
9206 results in failures being hidden.

9240 (AC_C_CONST): Same.
9241 (AC_C_INLINE): Same.
9242 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
9243 * doc/autoconf.texi, NEWS: Document.
9244 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
9245 AC_C_CROSS.
9247 2002-04-02 Akim Demaille <akim@epita.fr>
9249 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
9250 _AS_MKDIR_P_PREPARE.
9252 2002-03-28 Kevin Ryde <user42@zip.com.au>
9254 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9255 to avoid versions of HP C which don't allow that.
9257 2002-03-27 Paul Eggert <eggert@twinsun.com>
9259 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9260 (AS_SHELL_SANITIZE): Invoke it.
9261 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
9263 2002-03-26 Akim Demaille <akim@epita.fr>
9265 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
9267 2002-03-26 Akim Demaille <akim@epita.fr>
9269 * doc/autoconf.texi (Introduction): The GNATS base moved.
9271 2002-03-25 Paul Eggert <eggert@twinsun.com>
9273 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9274 as POSIX requires, as it doesn't work with Zsh.
9275 * doc/autoconf.texi (Assignments): Document the problem.
9277 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9279 * doc/autoconf.texi (Limitations of Make): Mention more issue
9280 about VPATH, overriding of macros in sub-makes, and handling of
9281 SHELL.
9283 2002-03-21 Paul Eggert <eggert@twinsun.com>
9285 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9286 problem with here-document buffer boundaries.
9288 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9289 when reinvoking the shell, to work around problems with installers
9290 who put strange things like "cd" commands in their environments.
9292 2002-03-19 Akim Demaille <akim@epita.fr>
9294 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9295 From Aaron Ucko.
9297 2002-03-19 Akim Demaille <akim@epita.fr>
9299 * bin/autoscan.in (scan_file): Specify the location in `&used'
9300 invocations.
9301 From Nicolas Joly.
9303 2002-03-19 Akim Demaille <akim@epita.fr>
9305 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
9306 From Nishio Futoshi.
9308 2002-03-19 Akim Demaille <akim@epita.fr>
9310 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9312 2002-03-18 Paul Eggert <eggert@twinsun.com>
9314 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9315 (Limitations of Usual Tools): Add mkdir section.
9317 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9318 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9319 back on AS_DIRNAME to compute prefixes otherwise; this is
9320 roughly what mkinstalldirs does. That way, we need not have
9321 our own filename disassembler. The old disassembler did not
9322 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9324 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9325 Create at_test_all by a series of assignments,
9326 not by a single assignment of a long string. The latter causes ksh
9327 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9328 presumably because of a buffer overrun.
9330 2002-03-14 Paul Eggert <eggert@twinsun.com>
9332 * lib/autotest/general.m4 (at_times_skip):
9333 Renamed from at_times. Now a boolean.
9334 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9335 says 'times: not found'.
9337 2002-03-14 Akim Demaille <akim@epita.fr>
9339 * bin/autoreconf.in (&study_gettextize): New.
9340 (&autoreconf): Handle newest gettextize.
9341 Rerun aclocal if needed.
9342 Suggested by Andreas Schwab.
9344 2002-03-13 Akim Demaille <akim@epita.fr>
9346 * doc/autoconf.texi (Special Shell Variables): More about IFS.
9348 2002-03-13 Akim Demaille <akim@epita.fr>
9350 * doc/autoconf.texi (Header Portability): New.
9351 Add information about stdint.h and inttypes.h from Paul Eggert.
9353 2002-03-13 Akim Demaille <akim@epita.fr>
9355 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9356 -p'.
9357 From Bob Proulx.
9359 2002-03-12 Akim Demaille <akim@epita.fr>
9361 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9362 m4_require.
9364 2002-03-11 Andreas Schwab <schwab@suse.de>
9366 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9367 does not do it if --with-lispdir is given.
9369 2002-03-08 Akim Demaille <akim@epita.fr>
9371 Version 2.53.
9373 2002-03-08 Akim Demaille <akim@epita.fr>
9375 * doc/autoconf.texi (Subdirectories): Clarify that the
9376 subdirectory should exist.
9378 2002-03-08 Akim Demaille <akim@epita.fr>
9380 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9382 2002-03-08 Akim Demaille <akim@epita.fr>
9384 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9385 aliases the actual variables, and modifications of the former
9386 affect the latter.
9388 2002-03-08 Akim Demaille <akim@epita.fr>
9390 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9391 because of C-c: have m4 output in tmp files, then mv them.
9393 2002-03-08 Akim Demaille <akim@epita.fr>
9395 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
9396 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
9397 * bin/ifnames.in: Copyright update.
9399 2002-03-08 Akim Demaille <akim@epita.fr>
9401 * doc/autoconf.texi (Invoking autom4te): New.
9403 2002-03-05 Akim Demaille <akim@epita.fr>
9405 * doc/autoconf.texi (Specifying Names): Clarification suggested by
9406 Kevin Ryde.
9408 2002-03-05 Akim Demaille <akim@epita.fr>
9410 Version 2.52i.
9412 2002-03-04 Akim Demaille <akim@epita.fr>
9414 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
9415 * lib/autoconf/general.m4 (AC_INIT): More informative error
9416 message for LIBOBJ.
9418 2002-03-04 Akim Demaille <akim@epita.fr>
9420 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
9421 parallel builds.
9423 2002-03-04 Akim Demaille <akim@epita.fr>
9425 * doc/autoconf.texi (Transforming Names): Equality between target
9426 and host is irrelevant.
9427 (Specifying Names, Canonicalizing): Remove all references to the
9428 backward compatibility hooks. Rather, collect them all into...
9429 (Hosts and Cross-Compilation): this new section.
9430 * doc/install.texi (System Type): Ditto.
9431 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9432 that `--host' implies cross-compilation.
9434 2002-03-04 Akim Demaille <akim@epita.fr>
9436 * doc/autoconf.texi (Evaluation Macros): New.
9437 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9438 useless.
9439 (_m4_foreach): Define the variant with immediate evaluation so
9440 that it contains exactly the items, not an expression which
9441 evaluation is the current item.
9442 (m4_re_string, m4_re_word): Don't over quote them.
9444 2002-03-04 Akim Demaille <akim@epita.fr>
9446 Instead of having stacking `shift's evaluated at the end, let
9447 `foreach' loops immediately evaluate them.
9449 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9450 $*. This is the n-th time I change my mind, but hopefully this is
9451 the last...
9452 (m4_lquote): New.
9453 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9454 efficient.
9455 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9456 it was only a hack for m4_text_wrap.
9457 (m4_car2): Remove, replaced by...
9458 (m4_cdr): New.
9459 (_m4_foreach): Adjust.
9460 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9461 m4_bpatsubst for clarification.
9463 2002-03-04 Akim Demaille <akim@epita.fr>
9465 * doc/autoconf.texi (Changequote is Evil): New.
9467 2002-03-03 Kevin Ryde <user42@zip.com.au>
9469 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
9470 on old systems like SunOS.
9472 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
9474 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9475 lib/autoconf/functions.m4, lib/autoconf/general.m4,

9489 2002-02-25 Akim Demaille <akim@epita.fr>
9491 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
9492 From Akinori Musha.
9494 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
9496 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
9497 translate \r\n to \n.
9499 2002-02-07 Akim Demaille <akim@epita.fr>
9501 Version 2.52h.
9503 2002-02-07 Akim Demaille <akim@epita.fr>
9505 Fix Autoconf PR/209.
9506 Also reported by Frank Denis.
9508 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
9510 2002-02-07 Akim Demaille <akim@epita.fr>
9512 Fix Autoconf PR/207:
9513 AC_PREFIX_PROGRAM fails with dashed program names
9515 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
9516 variable when looking for the prefix program.
9517 Now it also works for shell variables.
9519 2002-02-07 Akim Demaille <akim@epita.fr>
9521 * doc/autoconf.texi (Limitations of Builtins): More about
9522 case/esac.
9524 2002-02-06 Akim Demaille <akim@epita.fr>
9526 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
9527 case/esac, some shells don't support it.
9528 Reported by Zack Weinberg.
9529 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
9531 2002-02-06 Akim Demaille <akim@epita.fr>
9533 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
9534 sure not to introduce newlines in at_groups.
9535 * lib/autotest/Makefile.am (autotest.m4f): Typo.
9537 2002-02-06 Akim Demaille <akim@epita.fr>
9539 * tests/torture.at (Configuring subdirectories): Skip if aclocal
9540 is not available.
9542 2002-02-05 Paul Eggert <eggert@twinsun.com>
9544 * doc/autoconf.texi (Specific Compiler Characteristics):
9545 Describe HP-UX cc bug workaround more accurately.
9546 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
9547 not unsigned long.
9548 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
9549 cross-compilers, too. This undoes some of the most recent change
9550 to this file.
9552 2002-02-05 Akim Demaille <akim@epita.fr>
9554 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
9555 to make sure they are up to date when `check' is run.
9557 2002-02-05 Akim Demaille <akim@epita.fr>
9559 * doc/autoconf.texi (Making testsuite Scripts): Document
9560 package.m4.
9562 2002-02-05 Akim Demaille <akim@epita.fr>
9564 * lib/freeze.mk: New.
9566 2002-02-05 Akim Demaille <akim@epita.fr>
9568 Implement `autom4te --freeze'.
9570 * bin/autom4te.in (&freeze): New.
9571 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9572 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9574 2002-02-05 Akim Demaille <akim@epita.fr>
9576 * bin/autom4te.in (&parse_args): Implement `frozen files are
9577 optional are the sum of the previous files on the command line'.
9578 Also, pass `--reload-state=' on them, so...
9579 (handle_m4): don't.
9580 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9581 (M4sh): Rely on M4sugar.
9582 (Autotest, M4sh, M4sugar): Use frozen files.
9584 2002-01-31 Akim Demaille <akim@epita.fr>
9586 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
9587 * doc/autoconf.texi (Initializing configure): Adjust.
9589 2002-01-30 Akim Demaille <akim@epita.fr>
9591 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
9592 alphanumeric to `-' instead of `_'.
9594 2002-01-30 Akim Demaille <akim@epita.fr>
9596 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
9597 for plain code, the other for cross-compilation code. The latter
9598 is now run with GCC only.
9599 * doc/autoconf.texi (Compilers and Preprocessors): New.
9601 2002-01-30 Akim Demaille <akim@epita.fr>
9603 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
9604 values.
9605 * doc/autoconf.texi (Initializing configure): Explain how to
9606 change AC_INIT default values.
9608 2002-01-29 Akim Demaille <akim@epita.fr>
9610 * tests/torture.at (Configuring subdirectories): Use configure.in,
9611 so that aclocal 1.4 works.
9612 Reported by Alexandre Duret-Lutz and Larry Schmitt.
9614 2002-01-28 Akim Demaille <akim@epita.fr>
9616 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9617 needs an argument.
9619 2002-01-28 Akim Demaille <akim@epita.fr>
9621 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9622 AUTOTEST_PATH *after* it was set.
9623 Don't put `.' in the PATH: the user should be precise and `./' if
9624 needed. In addition, given that the test suite does some `cd', if
9625 `.' is in the path, the `tested programs' sections will report
9626 programs found in the test suite's directory, while during the
9627 tests (performed in their own directory), these programs are no
9628 longer visible. In other words, the results is confusing and
9629 useless.
9630 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
9632 2002-01-24 Akim Demaille <akim@epita.fr>
9634 Version 2.52g.
9636 2002-01-24 Akim Demaille <akim@epita.fr>

9639 * doc/autoconf.texi: Finally add Akim as an author.
9641 2002-01-24 Akim Demaille <akim@epita.fr>
9643 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
9644 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
9645 Bourne. Use /bin/sh.
9646 From Andreas Buening.
9648 2002-01-24 Akim Demaille <akim@epita.fr>
9650 * config/config.guess, config/config.sub, config/texinfo.tex:

9659 * config/strip.m4: Remove, to ease sync'ing with any version of
9660 Automake.
9662 2002-01-24 Akim Demaille <akim@epita.fr>
9664 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
9665 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
9666 Reported by Geir Ove Myhr.
9668 2002-01-21 Akim Demaille <akim@epita.fr>
9670 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
9672 2002-01-21 Akim Demaille <akim@epita.fr>
9674 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
9675 message on invalid options.
9676 * bin/autom4te.in (parse_args): Don't use
9677 Autoconf::General::getopt with non valid options.
9679 2002-01-17 Jim Meyering <meyering@lucent.com>
9681 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
9682 $ac_cv_exeext so we don't use an old, invalid, cached value.
9684 2002-01-11 Akim Demaille <akim@epita.fr>
9686 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
9687 Meyering.
9688 * doc/autoconf.texi (Function Portability): Document the strnlen
9689 limitation.

9691 * lib/autoscan/functions: Adjust.
9693 2002-01-06 Akim Demaille <akim@epita.fr>
9695 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
9696 package.m4, since is really depends upon configure.ac, not
9697 configure.
9698 * doc/autoconf.texi (testsuite Scripts): Adjust.
9699 * tests/Makefile.am (package.m4): New.
9700 EXTRA_DIST it since its a source.
9702 2002-01-06 Akim Demaille <akim@epita.fr>
9704 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
9705 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
9706 and PACKAGE_BUGREPORT from here...
9707 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
9708 arguments.
9709 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
9710 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
9711 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
9712 * tests/tools.at (autoheader): Adjust.
9713 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
9715 2002-01-06 Akim Demaille <akim@epita.fr>
9717 * bin/autoscan.in (scan_file): Use `&used'.
9719 2002-01-03 Akim Demaille <akim@epita.fr>
9721 * doc/autoconf.texi (Output): Improved wording regarding use of
9722 AC_OUTPUT.
9723 From Olly Betts.
9725 2001-12-18 Kevin Ryde <user42@zip.com.au>
9727 * doc/autoconf.texi (Function Portability): Add notes on sscanf
9728 sometimes needing writable input.
9730 2001-12-17 Jim Meyering <meyering@lucent.com>
9732 * doc/autoconf.texi (New Macros): Tweak wording.
9734 2001-12-14 Akim Demaille <akim@epita.fr>
9736 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
9737 trailing files, don't apply `-rf' to files which might not be
9738 created by configure (core, core.*, and *.core), but just `rm -f'.
9739 Suggested by Jonathan Kamens.
9741 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
9743 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
9745 2001-12-14 Akim Demaille <akim@epita.fr>
9747 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
9749 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
9751 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
9752 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
9753 abs_srcdir, top_srcpath to abs_top_srcdir.
9754 (_AC_OUTPUT_FILES): Adjust.
9755 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
9756 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
9757 * tests/wrappl.in, tests/wrapsh.in: Adjust.
9759 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
9761 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
9762 C/Fortran linking on HP/UX, by extracting the Fortran library
9763 search path from the LPATH line in the $F77 -v output.
9765 2001-12-12 Kevin Ryde <user42@zip.com.au>
9767 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
9768 forbidden file descriptors table.
9770 2001-11-26 Akim Demaille <akim@epita.fr>
9772 * bin/autoscan.in (%c_keywords): Build it at top level.
9773 Map to 1 in order to simplify its uses.
9775 2001-11-26 Akim Demaille <akim@epita.fr>
9777 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
9778 Remove $filepath, useless.
9779 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
9780 variables, they are really part of the tokens.
9781 Split the input line on spaces and then look for tokens.
9782 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
9783 because of `lex$U.$(OBJEXT)'.
9784 (&scan_files): Use "@list" instead of join.
9785 * doc/Makefile.am (CLEANFILES): Add *.fns.
9787 2001-11-26 Akim Demaille <akim@epita.fr>
9789 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
9790 Remove, replaced by...
9791 * tests/wrappl.in: Be common for all the Perl executables.
9792 In particular autoscan and autoheader want -I.
9793 * configure.ac: Adjust.
9794 * lib/autoscan/headers: errno.h is portable.
9796 2001-11-26 Akim Demaille <akim@epita.fr>
9798 * bin/autoscan.in (used): New.
9799 Use it.
9801 2001-11-26 Akim Demaille <akim@epita.fr>
9803 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
9804 directives.
9805 (&scan_sh_file): Remove a duplicate pattern.
9806 (&check_configure_ac): Use long options.
9807 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
9809 2001-11-26 Akim Demaille <akim@epita.fr>
9811 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
9812 Before, having a line containing the opening of a multi line
9813 comment made the whole line be ignored.
9815 2001-11-26 Akim Demaille <akim@epita.fr>
9817 * doc/autoconf.texi (Using an Autotest Test Suite): New.
9818 (testsuite Scripts): Be one of its subsection.
9819 (Autotest Logs): New.
9821 2001-11-26 Akim Demaille <akim@epita.fr>
9823 Test groups are now run two directories deeper.
9825 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
9826 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
9827 at_top_builddir.
9828 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
9829 top_srcdir, builddir and top_builddir.
9830 Use `at_*dir' relatively to the directory containing the
9831 suite, use `*dir' when relatively to the current group dir.
9833 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
9835 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
9836 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
9837 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
9838 spelling errors.
9840 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9842 * doc/autoconf.texi (Using System Type): Add an example of `case
9843 $host' usage so people quit using `case $target' everywhere.
9845 2001-11-22 Akim Demaille <akim@epita.fr>
9847 * doc/autoconf.texi (Installation Directory Variables): Englishoes
9848 spotted by Jim Meyering.
9850 2001-11-16 Paul Eggert <eggert@twinsun.com>
9852 This patch implements a `long double' suggestion by Oliver Kiddle.
9854 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
9855 static, to catch errors if the value isn't known at compile-time
9856 and the compiler supports dynamic arrays. Change its name from
9857 `_array_' to `test_array' to avoid potential name clashes.
9858 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
9859 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
9860 better than double. Catch a bug in GCC 2.95.2 x86.
9861 * doc/autoconf.texi (C Compiler): Document the above.
9862 * NEWS: Likewise.
9864 2001-11-13 Akim Demaille <akim@epita.fr>
9866 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
9867 hand.
9868 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
9870 2001-11-13 Akim Demaille <akim@epita.fr>
9872 * lib/autotest/general.m4 (AT_INIT): After having run the test
9873 group, go back to the initial directory, not to at_suite_dir.
9875 2001-11-13 Akim Demaille <akim@epita.fr>
9877 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
9878 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
9879 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
9880 option.
9881 (AT_CHECK_CONFIGURE): Use absolute paths.
9882 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
9883 The problem is still the old one: there is no means in M4 (that I
9884 know about) to create a defining macro, because there is no means
9885 to create `$1' etc., therefore, the defining macro ``swallows''
9886 all the arguments meant to the defined macro.
9888 2001-11-13 Akim Demaille <akim@epita.fr>
9890 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
9891 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
9892 configure.ac.
9893 * tests/aclocal.m4: Remove, as it is no longer used.
9895 2001-11-13 Akim Demaille <akim@epita.fr>
9897 * lib/autotest/general.m4: Change `tests?' into `groups?' in
9898 variable names when referring to a single test group, or to
9899 `suite' when referring to the whole test suite.
9900 `at_last_test' is removed: m4 compute at_format itself.
9901 (at_stdout, at_stder1, at_stderr): New variables.
9902 (AT_CHECK): Use them.
9904 2001-11-13 Akim Demaille <akim@epita.fr>
9906 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
9907 in PATH.
9908 Create `testsuite.dir/003/run' instead of `testsuite.003'.
9909 Do it as soon as a test fails, don't wait till the end of the test
9910 suite.
9911 Don't remove $as_me.[0-9]*, since these files no longer exist.
9913 2001-11-13 Akim Demaille <akim@epita.fr>
9915 * tests/tools.at: Use absolute paths, since we are no longer run
9916 in place.
9918 2001-11-13 Akim Demaille <akim@epita.fr>
9920 Now that tests are running in their own private dir, there is no
9921 need to list the files to remove at the end of tests groups.
9923 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
9924 (AT_data_files, at_data_files): Remove.
9925 (AT_CLEANUP, AT_DATA): Simplify.
9926 (AT_INIT): Adjust.
9927 Remove the group dir if !debug && !failed.
9928 * tests/atspecific.m4: Adjust.
9930 2001-11-13 Akim Demaille <akim@epita.fr>
9932 Start a new layout for Autotest: `testsuite' creates
9933 `testsuite.dir' in which the at-check-line etc. files are to be
9934 found, and `testsuite.dir/003' where the test group 3 is run.
9936 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
9937 at_check_line_file, at_format, at_test_normalized, at_group_dir
9938 are new variables.
9939 Create the directories.
9940 Use absolute paths for at- files.
9941 (AT_CHECK): Adjust.
9943 2001-11-11 Michael Matz <matz@kde.org>
9945 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
9946 (m4_car2): New.
9947 (m4_car): Properly quote arguments.
9949 2001-11-13 Akim Demaille <akim@epita.fr>
9951 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
9952 with stricter rules on LIBOBJS.
9954 2001-11-12 Paul Eggert <eggert@twinsun.com>
9956 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
9957 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
9958 __PROTOTYPES too.
9960 2001-11-12 Akim Demaille <akim@epita.fr>
9962 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
9964 2001-11-12 Akim Demaille <akim@epita.fr>
9966 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9967 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
9968 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9969 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
9970 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
9971 specify to what the macro should be defined (typically to 1).
9973 2001-11-12 Akim Demaille <akim@epita.fr>
9975 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
9976 From Jim Meyering.
9978 2001-11-12 Akim Demaille <akim@epita.fr>
9980 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
9981 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
9982 definition used by Automake where LEX is +/- "${missing} lex" and
9983 `missing' itself contains variables.
9985 2001-11-12 Akim Demaille <akim@epita.fr>
9987 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
9988 Now that M4sh pushes BODY, the comments were output at the end of
9989 the test suites.
9991 2001-11-08 Akim Demaille <akim@epita.fr>
9993 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
9994 that we can trace macros from aclocal.m4.
9995 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
9996 obsoleted, and redirect to the former anyway.
9997 Reported by Ralf Corsepius.
9999 2001-11-08 Akim Demaille <akim@epita.fr>
10001 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10002 processed only if present.
10003 * tests/torture.at (Configuring subdirectories): Use autoreconf
10004 instead of successive calls to autoconf.
10005 Add a nonexistent subdirectory to exercise the patch above.
10006 Reported by Ralf Corsepius.
10008 2001-11-08 Kevin Ryde <user42@zip.com.au>
10010 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10011 doesn't accept .S files.
10013 2001-11-07 Akim Demaille <akim@epita.fr>
10015 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
10016 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
10017 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10018 * bin/autom4te.in (warn_forbidden): New.
10019 (handle_output): Use it.
10020 Read m4_pattern_forbid with messages.
10022 2001-11-05 Akim Demaille <akim@epita.fr>
10024 * bin/autom4te.in (--normalize): Remove.
10025 * lib/autom4te.in: Adjust.
10027 2001-11-05 Akim Demaille <akim@epita.fr>
10029 * tests/Makefile.am (testsuite): Rename this target as...
10030 ($(TESTSUITE)): this.
10031 From Nicolas Joly.
10033 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10035 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10036 the --prefix option, also remove it's argument.
10038 2001-11-05 Akim Demaille <akim@epita.fr>
10040 * doc/autoconf.texi (testsuite Invocation): Update.
10041 (Writing testsuite.at): Update.
10043 2001-11-03 Akim Demaille <akim@epita.fr>
10045 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10047 2001-11-03 Akim Demaille <akim@epita.fr>
10049 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10050 (&file_name_is_absolute): New, wrappers around routines from
10051 File::Spec.
10052 Use and export them.
10053 (&find_configure_ac): Optionally take a directory where to look at.
10054 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10055 the arguments.
10056 Default @ARGV to `.', not find_configure_ac.
10057 (&autoreconf): Argument is a directory.
10058 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10059 * doc/autoconf.texi (autoreconf Invocation): Update.
10061 2001-11-03 Akim Demaille <akim@epita.fr>
10063 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10064 (@export_forward_subs): New.
10065 Add basename, dirname, and fileparse.
10066 (@EXPORT): Adjust.
10067 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10068 Don't look for aclocal flags if we already know aclocal is not
10069 used.
10070 Move aclocal.m4t only if it exists.
10071 Reported by Ezra Peisach.
10073 2001-11-03 Akim Demaille <akim@epita.fr>
10075 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10076 passed on command line, defaulting to ./configure.ac if present.
10077 (&maybe_autoreconf, File::Find): Remove, unused.
10078 (&autoreconf): If autoconf is not used, don't try to trace.
10080 2001-11-02 Akim Demaille <akim@epita.fr>
10082 * configure.ac: Bump to 2.52g.
10084 2001-11-02 Akim Demaille <akim@epita.fr>
10086 Version 2.52f.
10088 2001-11-02 Akim Demaille <akim@epita.fr>
10090 * config/config.guess, config/config.sub, doc/standards.texi:
10091 * config/lispdir.m4: Update from masters.
10092 * configure.ac: Bump to 2.52f.
10094 2001-11-02 Akim Demaille <akim@epita.fr>
10096 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10097 Don't run aclocal when aclocal.m4 is not from aclocal.
10098 From Ezra Peisach.
10099 Don't run libtoolize and gettextize if --install is not given.
10101 2001-11-01 Paul Eggert <eggert@twinsun.com>
10103 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10104 be invoked before _AS_LINENO_PREPARE.
10105 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10106 than character ranges.
10108 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10109 invoking AS_BASENAME. Set the locale variables to 'C' if
10110 possible, as POSIX requires this to get the traditional
10111 behavior.
10112 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10114 2001-10-31 Paul Eggert <eggert@twinsun.com>
10116 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10117 with {}, as that triggers a bug in Bash 2.05.
10119 (_AS_LINENO_PREPARE): Use Sed rather than
10120 Awk. Fix the sed prepass to work even if there are multiple
10121 instances of $LINENO on the same line. Do not substitute for
10122 other variables like $LINENOT. Do not check file dates; such a
10123 check is unreliable on sufficiently fast machines, and removing
10124 the check makes the code simpler and more reliable. Check for
10125 output and chmod failures.
10127 * doc/autoconf.texi (Special Shell Variables): Document
10128 the above.
10130 2001-10-31 Akim Demaille <akim@epita.fr>
10132 * tests/Makefile.am (atconfig): Remove this target, Automake
10133 handles it now.
10135 2001-10-31 Akim Demaille <akim@epita.fr>
10137 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10138 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10139 provided, while it is optional.
10140 * configure.ac: Adjust.
10142 2001-10-26 Paul Eggert <eggert@twinsun.com>
10144 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10145 lib/Autom4te/Struct.pm:
10146 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10147 with 5.005_02.
10149 * doc/autoconf.texi (Special Shell Variables): Document some
10150 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10152 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10153 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10154 eval $LINENO is not portable in practice.
10156 2001-10-24 Akim Demaille <akim@epita.fr>
10158 * lib/Autom4te/General.pm (backname): New.
10160 2001-10-24 Akim Demaille <akim@epita.fr>
10162 * m4/: Remove, merged into...
10163 * config/: here.
10165 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10167 * doc/autoconf.texi (Shellology): Mention the problems with bash
10168 2.05's use of ANSI quoting in its `set' builtin.
10170 2001-10-22 Paul Eggert <eggert@twinsun.com>
10172 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10173 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10174 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10175 POSIX decided to standardize on the int flavor of strerror_r.
10176 Always do char* test, as there's no reason not to.
10177 Assign to a char* var, to catch strerror_r that returns int*.
10179 * doc/autoconf.texi (Particular Functions):
10180 Document the above changes. Also, document the fact that
10181 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10183 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10185 2001-10-20 Akim Demaille <akim@epita.fr>
10187 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
10188 the executable was missing from the log.
10190 2001-10-20 Akim Demaille <akim@epita.fr>
10192 * lib/Autom4te/General.pm (&update_file): If destination is
10193 unchanged, remove the source.
10194 (&up_to_date_p): Don't be verbose, be debug.
10195 * bin/autoreconf.in: No longer support --m4dir.
10196 (&autoreconf): Display the full path of the configure.ac we are
10197 studying.
10198 Trace it only once.
10199 Be sure to honor --force with gettextize.
10200 Always run aclocal.
10201 * doc/autoconf.texi: Adjust.
10203 2001-10-20 Akim Demaille <akim@epita.fr>
10205 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10206 Remove, dead.
10207 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10208 `intl' is already present, as it refuses unless --force.
10209 (&parse_args): Use -I, --include instead of the old Autoconf
10210 options.
10211 ($localdir, $autoconf_dir): Remove.
10212 (@include): New.
10213 (&maybe_autoreconf): New, to preserve $_ for File::Find.
10215 2001-10-19 Jens Petersen <petersen@redhat.com>
10217 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
10218 * doc/autoconf.texi (Particular Programs): Likewise.
10220 2001-10-19 Akim Demaille <akim@epita.fr>
10222 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
10223 file in @configure_input@.
10224 Don't mention `automatically' in addition to `generated'.

10245 (AS_BASENAME_EXPR): New macro.
10246 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10247 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10248 and fall back on 'sed' only if the other two fail. This makes
10249 AS_BASENAME act more like AS_DIRNAME.
10250 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10251 contains white space.
10252 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):

10398 ourselves with CONFIG_SHELL.
10400 2001-10-05 Paul Eggert <eggert@twinsun.com>
10402 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

10487 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

10532 enough.

10673 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
10674 be used instead of ':'.
10675 * lib/autotest/general.m4: Replace occurrences of ':' in
10676 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
10678 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10680 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
10681 arguments. Fixed a typo.
10683 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10685 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
10686 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
10688 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10690 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
10691 * bin/autoupdate.in: Ditto.
10692 * bin/autoheader.in: Reworded a few comments.
10693 * bin/autoconf.in: Reworded help text for a few options.
10694 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10695 * bin/autoscan.in, bin/autoupdate.in: Ditto.
10697 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10699 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
10700 already have $file). Set output files to binary mode (helps avoid
10701 CR issues on DOSish systems).
10703 2001-09-19 Akim Demaille <akim@epita.fr>
10705 * lib/autotest/general.m4: Englishoes.
10706 From Tim Van Holder and Alexey Mahotkin.
10708 2001-09-18 Paul Eggert <eggert@twinsun.com>
10710 * doc/autoconf.texi (Common Shell Constructs): New node,
10711 documenting AS_DIRNAME.
10712 (Limitations of Usual Tools): Refer to it when discussing dirname.
10713 Also, update discussion of POSIX standard to reflect latest draft.
10715 * lib/autoconf/c.m4:
10716 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
10718 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10719 Do not pass a first argument with leading '-'
10720 to expr, by parenthesizing initial integers that might be negative.
10722 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
10723 now merely checks whether it is an error to pass an argument
10724 to getpgrp.
10726 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
10727 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
10728 whether it is a (compile-time) error to pass an argument to
10729 getpgrp. This simpler test supports the revised documentation,
10730 and is all that AC_FUNC_GETPGRP's users really need.
10732 2001-09-18 Akim Demaille <akim@epita.fr>
10734 * doc/autoconf.texi (Limitations of Make) <$<>: New.
10736 2001-09-18 Akim Demaille <akim@epita.fr>
10738 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
10739 `{}'.
10740 * lib/autotest/general.m4 (AT_INIT): Adjust.
10742 2001-09-18 Paul Wagland <paul@wagland.net>
10744 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
10745 correctly.
10746 Add test for AS_BASENAME.
10747 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
10748 added test. It now correctly handles /1/2/3/, returning '3' not ''.
10749 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
10750 * tests/base.at: Fixed the expected responses. The old ones were
10751 one line out...
10752 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
10753 the documentation claims it should (and how it behaved in 2.13).
10755 2001-09-18 Akim Demaille <akim@epita.fr>
10757 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
10758 the AC_CONFIG_COMMANDS invocation.
10759 This also solves the name clash problems.
10760 Don't set the package's ID.
10761 * lib/m4sugar/Makefile.am (version.m4): Revamp.
10762 No longer to be shipped.
10763 (version.in): Remove.
10764 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
10765 * lib/autoconf/status.m4: Adjust.
10766 Use `m4_PACKAGE_STRING'.
10767 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
10768 the only optional argument is the name of the test suite.
10769 Expect `package.m4' to define the package signature.
10770 * lib/autom4te.in (Autotest): Add `package.m4?'.
10771 * tests/Makefile.am (package.m4): New.
10772 * tests/suite.at: ifnames is a victim.
10774 2001-09-18 Akim Demaille <akim@epita.fr>
10776 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
10777 AC_LIBSOURCE, AC_CONFIG_FILES.
10778 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
10779 program version string doesn't match the package's.
10780 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
10781 after `(cached)'.
10783 2001-09-17 Paul Eggert <eggert@twinsun.com>
10785 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10786 Allow expression to return any value that can fit into unsigned long
10787 (not int, as before). Check for output errors.
10789 2001-09-17 Bruno Haible <haible@ilog.fr>
10791 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10792 Always include <stdio.h> and <stdlib.h>. Evaluate
10793 the expression in an extra function before these includes. Call
10794 fprintf "%d" only after ensuring the argument is of type 'int'.
10795 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
10797 2001-09-17 Paul Eggert <eggert@twinsun.com>
10799 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
10800 or CFLAGS=-O5. In that case, the linker has a relaxed view of
10801 fatal errors, and AC_CHECK_LIB causes it to include libraries even
10802 when they don't exist.
10804 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
10805 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
10806 need it.
10808 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
10809 version with the version used by fileutils 4.1, except use
10810 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
10811 we don't need it.
10813 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
10815 2001-09-13 Akim Demaille <akim@epita.fr>
10817 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
10818 _first_.
10819 Reported by Gerrit P. Haase.
10821 2001-09-13 Akim Demaille <akim@epita.fr>
10823 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

10830 Use it.

10839 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
10840 Likewise.

10843 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
10844 AT_tests_all for consistency.
10845 Set at_victims.
10846 (AT_VICTIMS): Similar to AT_KEYWORDS.
10847 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
10849 2001-09-13 Akim Demaille <akim@epita.fr>
10851 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
10853 2001-09-13 Akim Demaille <akim@epita.fr>
10855 * lib/autotest/general.m4 (AT_INIT): Create and remove
10856 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
10857 test suites can cohabit.
10859 2001-09-13 Akim Demaille <akim@epita.fr>
10861 * tests/mktests.sh: Don't output banners for empty test files.
10863 2001-09-13 Akim Demaille <akim@epita.fr>
10865 Test suites can be run independently of configure.

10913 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

10944 Move toward possibly stand-alone test suites.
10946 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
10947 in addition, it introduces useless differences in logs.

10967 2001-09-05 Akim Demaille <akim@epita.fr>

10970 the maintainer is dumb enough to do that...
10972 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
10973 excellence in M4 quotation: consider `__file__' is active.

11006 New, extracted from main.
11007 Use IO::File wherever possible.
11008 (input.m4): Be constant, use -I instead of hard coding $tmp.

11010 Don't invoke `_au_disable', since ac was not loaded, but just
11011 `unm4.m4'.
11013 2001-08-31 Akim Demaille <akim@epita.fr>

11046 * lib/Autom4te/General.pm (&find_file): Browse the includes in the

11057 autom4te_perllibdir.
11059 2001-08-31 Akim Demaille <akim@epita.fr>
11061 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

11067 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11068 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11069 Use directly autom4te, not autoconf.

11096 the time stamps.

11125 Forward autom4te's options instead of interpreting them.
11126 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11127 There is no such envvar since the inception of autom4te.cfg.
11128 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11129 * bin/autoupdate.in: Adjust, and perform more control.
11130 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
11131 * tests/autoconf: Dittowise.
11133 2001-08-31 Akim Demaille <akim@epita.fr>
11135 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
11136 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11137 optionally `FILE'.
11138 Use -e, not -f, since /dev/null for instance is OK.
11139 (&parse_args): Adjust.
11140 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11142 2001-08-31 Akim Demaille <akim@epita.fr>
11144 * configure.ac: Also find tested executables in bin.
11145 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11146 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11147 installed peer executables, only PATH is allowed to resolve it.
11148 Pass `autoconf_dir' via options, not via invisible envvars.
11149 * lib/Autom4te/General.pm (&find_peer): Remove.
11150 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11151 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11152 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11153 find the executables for it.
11154 * tests/Makefile.am: Major cleanup. Too lazy to document...
11155 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11156 We only need PERL.
11157 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11158 indeed related to running the test suite, while passing
11159 --autoconf-dir and others is related to running non installed
11160 Autoconf executables. So don't do that, leave it to...
11161 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11162 * tests/autoscan: New.
11163 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11164 refer to library files: rely on --language.
11166 2001-08-29 Akim Demaille <akim@epita.fr>
11168 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
11169 s/--set/--language/.
11171 2001-08-29 Akim Demaille <akim@epita.fr>
11173 * doc/autoconf.texi: Strip the @nodes.
11174 Suggested by Paul Eggert.
11175 (Initializing configure): Typo.
11177 2001-08-29 Akim Demaille <akim@epita.fr>
11179 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11180 Suggested by Paul Eggert.
11182 2001-08-29 Akim Demaille <akim@epita.fr>
11184 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11185 download in a tmp dir.
11187 2001-08-29 Akim Demaille <akim@epita.fr>
11189 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
11190 case insensitive OSes out there :(

11200 (&parse_args): Support --mode, --set, and --melt.
11201 * bin/autoconf.in: Simplify and adjust.
11202 * tests/Makefile.am (AUTOMAKE): Use --set.
11203 * tests/atlocal.in: Adjust.
11204 * BUGS: distcheck and check are weak.
11206 2001-08-29 Akim Demaille <akim@epita.fr>
11208 * lib/autotest/general.m4: Use
11209 foo=`(command) 2>/dev/null`
11210 not
11211 foo=`command` 2>/dev/null
11212 (at-devnull): Rename as...
11213 (AT-devnull): this.
11214 (--clean): Remove AT-* files too.
11215 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.

11232 Support test ranges as arguments to the testsuite.
11233 Have -e imply -d as the help text suggested.
11235 2001-08-27 Akim Demaille <akim@epita.fr>
11237 * Makefile.maint: Formatting changes.
11238 (do-po-update, po-update, cvs-update, update): New targets.

11250 * lib/autotest/general.m4 (AT_INIT): Log the command line.
11251 Support `VAR=VAL' as arguments.

11253 may be set via the command line.
11255 2001-08-27 Akim Demaille <akim@epita.fr>
11257 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
11258 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
11259 first the build dirs, then the src dirs.

11265 at_data_files earlier.
11266 (--clean, -c): New option.
11267 * tests/Makefile.am: Use this option.
11269 2001-08-27 Akim Demaille <akim@epita.fr>
11271 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
11272 `ac_top_builddir' to mimic Automake's vocabulary, which much more
11273 readable.
11274 Adjust callers.
11275 * doc/autoconf.texi (Configuration Actions): Document the vars
11276 available in commands.
11277 Emphasize the risks of collisions in init-cmds.

11282 (Initializing configure): this new node.
11284 2001-08-27 Akim Demaille <akim@epita.fr>

11308 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.

11310 -> ac_dir).
11311 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
11312 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.

11340 (AMTAR): Help automake define it.

11342 needed, 1.5 can have a macro and a target with the same name.
11343 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
11344 * m4/strip.m4: New.

11357 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
11358 Adjust callers.
11359 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
11360 the name of the directory they're in, instead of the filename,
11361 since version.m4 is now in m4sugar, but m4_acversion must not be
11362 classified as an Autoconf macro.
11363 ($input_m4): Don't qualify the path to m4sugar.
11364 Rather, pass autoconf_dir to m4.
11365 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

11368 2001-08-27 Akim Demaille <akim@epita.fr>

11380 of config.log on traps.

11382 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
11383 for config.status'.
11384 Open the log as soon as possible.
11385 Use the same log introduction as configure's.
11387 2001-08-22 Paul Eggert <eggert@twinsun.com>
11389 * doc/autoconf.texi (Indices): New node.

11447 2001-08-20 Akim Demaille <akim@epita.fr>
11449 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
11450 * NEWS, README, README-alpha, TODO, tests/README: This package is
11451 `Autoconf', not `autoconf' (the executable).
11453 2001-08-20 Akim Demaille <akim@epita.fr>
11455 Info readers seem to need `Index' in the index node title :(
11457 * doc/autoconf.texi: Reverse the 2001-08-15 change which
11458 simplified index node names.
11460 2001-08-20 Akim Demaille <akim@epita.fr>
11462 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
11463 arguments are not literals.

11465 Specify the output variables, and macros defined.
11467 2001-08-20 Akim Demaille <akim@epita.fr>

11470 (Examining Syntax) <AC_TRY_COMPILE>

11502 2001-08-20 Akim Demaille <akim@epita.fr>
11504 Huh!?!?! There are still some user EOF tags used, which prevents
11505 their use in AC_CONFIG_COMMANDS for instance...
11507 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
11508 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
11509 `_CSEOF', or `_ATEOF', as appropriate.

11571 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

11644 (cvs-dist): depends upon it.
11646 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
11648 * tests/Makefile.am: Use a clean-local rule to remove
11649 autom4te.cache (it's a directory, not a file.
11650 * Makefile.am: Ditto (but maintainer-clean-local).
11652 2001-08-15 Akim Demaille <akim@epita.fr>
11654 * bin/autom4te.in (@m4_warning): New.
11655 (&handle_m4): Use it.
11656 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
11657 warnings are issued at each run.
11658 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
11659 is in the src tree.
11661 2001-08-15 Akim Demaille <akim@epita.fr>
11663 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
11664 don't waste time running `autoupdate --version' works.
11665 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
11667 2001-08-13 Akim Demaille <akim@epita.fr>

11735 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
11736 magic values from an object file when cross-compiling.
11737 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
11739 2001-08-10 Akim Demaille <akim@epita.fr>
11741 * bin/autom4te.in (&handle_output): Don't use `grep' with side
11742 effects.
11743 Suggested by Russ Allbery.
11745 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
11747 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
11748 current $prefix to the sub-configures.
11750 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
11752 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
11753 extension (needed on BeOS). Reported by Guido van Rossum.
11755 2001-08-09 Akim Demaille <akim@epita.fr>
11757 * bin/autom4te.in ($icache): Load it only if older than autom4te.
11759 2001-08-07 Akim Demaille <akim@epita.fr>
11761 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
11762 removed.
11763 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
11764 No need to remove the files before and after the each test, before
11765 each test and at the end of the suite is enough.
11766 Display only the children `times', not the shell's.
11767 If the test failed or was skipped, at-times is not available.
11769 2001-08-07 Akim Demaille <akim@epita.fr>
11771 Always produce testsuite.log, including when there are no
11772 failures. This helps getting information on skipped tests, and
11773 duration of the tests. Err, implement the latter btw.
11775 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
11776 Dump information on the first run of each test.
11777 (AT_CLEANUP): Create `at-times' containing the duration of the
11778 test group.
11780 2001-08-07 Akim Demaille <akim@epita.fr>
11782 The use of `dumpstat' revealed that `len' was used although it
11783 should not. m4_text_wrap was using it, but in the Autoconf world
11784 where it is legal. Hence (i) test M4sh in its own world, not
11785 Autoconf's, and (ii), ahem, fix the bug :)
11787 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
11788 does not like `' instead of [].
11789 (AT_INIT): Forbid `^_?AT_'.
11790 And don't output such tokens.
11791 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
11792 `script.as', and `autom4te.cache'.
11793 Remove `empty' and `macro' which are no longer used.
11794 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
11795 * tests/m4sugar.at: Use it.
11796 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
11798 2001-08-07 Akim Demaille <akim@epita.fr>
11800 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
11802 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
11804 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
11806 2001-08-04 Akim Demaille <akim@epita.fr>
11808 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
11809 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
11810 AC_TRY_LINK.
11811 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
11812 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
11813 (AC_F77_MAIN): Likewise.
11815 2001-08-04 Akim Demaille <akim@epita.fr>
11817 Don't rely on M4sugar outputting the patterns in files, since we
11818 might process the output _without_ running m4, hence without these
11819 files.
11821 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
11822 * bin/autom4te.in (@Request::includes): Remove, unused.
11823 (@Request::source): Rename as...
11824 (@Request::input): this.
11825 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
11826 (&handle_output): Fetch the patterns from the traces.
11827 `$forbidden' and `$allowed' are constant: use m//o.
11828 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
11829 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
11831 2001-08-04 Akim Demaille <akim@epita.fr>
11833 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
11834 autoconf', i.e., in addition to caching traces, cache the output.
11836 * bin/autom4te.in (Request::cache): Rename as...
11837 (Request::id): this.
11838 ($cache, $icache, $tcache, $ocache): New.
11839 (&handle_m4): Save M4 output in the cache instead of $tmp.
11840 (&handle_output): Adjust.
11841 (&up_to_date_p): Check that the output cache is up to date too.
11842 (top level): Run `&handle_m4' iff force or the cache is invalid.
11843 Run `&handle_output' if the output cache is more recent.
11845 2001-08-04 Akim Demaille <akim@epita.fr>
11847 * bin/autom4te.in ($force): New.
11848 (&parse_args, &print_usage): -f, --force is a new option.
11849 (&handle_output): CPP directives might have spaces after `#'.
11850 (&parse_args): The first file only can be frozen.
11852 2001-08-04 Akim Demaille <akim@epita.fr>
11854 Don't let autom4te compute the `include' traces several times:
11855 first check that the trace cache file is up to date, and then
11856 compare its timestamp with that of the output.
11858 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
11859 the preamble. Don't require 5.005 as Autom4te::General does it,
11860 and better yet (use `use', not `require'!).
11861 * lib/Autom4te/Struct.pm: Rename the last occurrences of
11862 Class::Struct as Autom4te::Struct.
11863 * lib/Autom4te/General.pm (File::stat): Use it.
11864 (&mtime): New, export it.
11865 * bin/autom4te.in: Use it.
11866 Declare `$req' is invalid if it is outdated.
11867 Don't declare it valid before saving it if something went wrong.
11869 2001-08-04 Akim Demaille <akim@epita.fr>
11871 Autom4te shall not encode Autoconf data, and preselecting traces
11872 must be proposed to the users.
11874 * bin/autom4te.in (@required_trace): Remove.
11875 (@preselect): New.
11876 (&parse_args, &print_usage): -p, --preselect is a new option.
11877 (&up_to_date_p): Adjust.
11878 * bin/autoconf.in: Preselect some Autoconf macros.
11880 2001-08-04 Akim Demaille <akim@epita.fr>
11882 * tests/tools.at (autoconf --trace: user macros): Check traces on
11883 macros invoked without arguments, and macros invoked with multiple
11884 lines arguments.
11886 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
11888 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
11889 arguments.
11891 2001-08-03 Akim Demaille <akim@epita.fr>
11893 * bin/autoconf.in ($@): Work around the usual sh bug.
11894 From Nicolas Joly.
11896 2001-08-03 Akim Demaille <akim@epita.fr>
11898 Clean up the handling of the M4 builtins tracing exception.
11900 * bin/autom4te.in (Request::request): Don't complete M4 builtins
11901 trace requests.

11903 (@m4_builtin): this.
11904 (%m4_builtin_alternate_name): New.
11905 (&parse_args): Complete the trace requests with alternate names.
11906 (&handle_traces): Hence no longer do it here.
11907 (&trace_requests): Remove, unused.
11909 2001-08-03 Akim Demaille <akim@epita.fr>
11911 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
11912 m4_if, and m4_wrap.
11914 2001-08-03 Akim Demaille <akim@epita.fr>
11916 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
11917 (m4_divert_pop): Dump the whole diversion stack when a diversion
11918 mismatch happens.
11919 * bin/autom4te.in (&handle_output): Remember of the first
11920 occurrence of a possibly undefined macro, not the last.
11921 Complain about the possibly undefined macros in the same order as
11922 the appear in the output.
11923 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
11924 * tests/tools.at (autoconf: forbidden tokens, basic)
11925 (autoconf: forbidden tokens, exceptions): No longer sort
11926 autoconf's stderr, as it is now deterministic.
11927 Check that `dnl' is caught.
11929 2001-08-01 Akim Demaille <akim@epita.fr>
11931 * configure.ac: Bump to 2.52c.

11945 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
11946 `die'.
11947 (&END): New.
11948 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
11949 `END', as `Autom4te::General::END' will be triggered.
11950 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
11951 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

12343 compiler, not the preprocessor.

12386 cross-language link tests can be performed successfully.
12387 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
12388 after $LIBS, for consistency; this should be the general rule since

12390 * doc/autoconf.texi: Document AC_F77_DUMMY_MAIN and AC_F77_MAIN.
12392 2001-06-29 Pavel Roskin <proski@gnu.org>

12395 at-stdout and at-stderr instead of removing the newline
12396 from the echo output, which is not guaranteed to work.
12398 2001-06-28 Jens Petersen <petersen@redhat.com>
12400 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to

12460 three as failures are unlikely, and speed matters.
12462 2001-06-23 Akim Demaille <akim@epita.fr>
12464 * doc/autoconf.texi (Redefined M4 Macros): New.
12466 2001-06-23 Akim Demaille <akim@epita.fr>
12468 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): Consider
12469 inttypes.h is missing if it conflicts with sys/types.h, as on IRIX

12474 * acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS): Defer parsing of
