1 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3 * NEWS: Version 2.61a.
5 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8 * NEWS: Document changes with echo and printf, and the lack
9 of limits on the total size of multi-line values of substituted
10 variables, and the AC_FUNC_FSEEKO fix.
12 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
14 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
15 Writing configure.ac.
16 (Autoconf Input Layout): Renamed from configure.ac Layout.
17 (Recreating a Configuration): Renamed from config.status Invocation.
18 (Obsolete Recreation): Renamed from Obsolete config.status Use.
19 (acconfig Header): Renamed from acconfig.h.
20 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
21 (Writing Testsuites): Renamed from Writing testsuite.at.
22 (Autom4te Cache): Renamed from autom4te.cache.
24 * BUGS: Remove mention of VPATH problem, since it's now documented
25 not to be a bug in the Autoconf build procedure itself, but rather
26 a problem with the proprietary `make' programs.
28 * doc/autoconf.texi (Build Directories): Add a cross reference
29 to VPATH and Make.
31 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
32 * doc/standards.texi: Sync from gnulib.
34 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
35 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
36 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
37 generated automatically.
39 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
41 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
42 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
43 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
45 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
47 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
48 `CEOF$ac_eof' special marker, the awk script cannot contain a
49 line matching `^CEOF', so this is not needed any more.
50 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
51 special marker in the test.
53 2006-12-06 Stepan Kasal <kasal@ucw.cz>
55 * tests/tools.at (autom4te preselections): Use `find -newer';
56 remove one of the sleeps.
58 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
59 more readable, using ...
60 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
62 * doc/autoconf.texi (autoheader Invocation): Do not double-
63 quote the parameter of `AH_BOTTOM' in the example.
65 2006-12-05 Stepan Kasal <kasal@ucw.cz>
67 * doc/autoconf.texi (Configuration Headers): Remove the
68 example with multiple input files.
69 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
70 multiple input files.
72 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
74 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
75 creating the awk substitution script, handle one input line at a
76 time, so that the maximum length of a substituted (multi-line)
77 value is not limited by the size of the sed pattern space.
78 The trade-off is a slightly repetitive sed script.
79 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
80 can only have up to 7 characters, due to Solaris 10 /bin/sed.
81 * tests/torture.at (Substitute a 2000-byte string): Increase the
82 test with several long lines, they should not be caught by sed
83 limits any more.
85 * tests/tools.at (autom4te preselections): New test, to flag
86 entries missing from autom4te.cfg.
87 Report by David Byron <dbyron@hheld.com>.
89 * tests/torture.at (Substitute a 2000-byte string): Actually use
90 AC_PROG_AWK, so the last change works as intended.
91 (Substitute and define special characters): Likewise.
92 (Substitute a newline): Likewise.
94 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
95 instead of `awk' consistently.
96 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
97 * tests/torture.at (Torturing config.status): Test both the
98 result of AC_PROG_AWK and plain awk.
99 (Substitute a 2000-byte string): Likewise.
100 (Substitute and define special characters): Likewise.
101 (Substitute a newline): Likewise.
103 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
105 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
106 can be assigned to a function pointer. Problem reported by
107 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
108 part of a patch by Ralf Wildenhues in that same bug report.
110 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
112 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
113 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
115 2006-12-01 Eric Blake <ebb9@byu.net>
117 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
118 cross-compiling from cygwin to mingw.
119 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
120 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
121 to lib/autoconf/c.m4.
123 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
125 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
126 string for more reliable failure. Wrap the entire test that
127 causes the broken Solaris printf to dump core, in a subshell,
128 so the segmentation fault message is reliably suppressed.
129 Fix shell expansion errors by using /usr/ucb/echo always;
130 avoid an error on systems without it by another subshell.
131 Avoid m4 expansion of `$1'. Set the zeroth argument of the
132 subshell-$as_echo to `as_echo', for better error message.
134 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
136 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
137 `BASH_SOURCE' contain a newline, set them to empty, as they may
138 not be unset.
140 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
142 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
143 years and is too hard to maintain now. The last straw was
144 reported by Jerker Baeck in
145 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
146 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
147 * doc/autoconf.texi (Particular Functions): Move
148 AC_FUNC_SETVBUF_REVERSED from here...
149 (Obsolete Macros): ... to here. Say that it does nothing now.
150 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
151 Turn into (almost) a no-op.
153 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
154 (AC_C_VOLATILE):
155 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
156 These macros are obsolescent and new applications shouldn't need them.
157 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
158 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
159 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
160 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
161 (AC_FUNC_VPRINTF): Likewise.
162 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
163 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
164 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
166 * doc/autoconf.texi (Setting Output Variables): Mention that
167 @VAR1@VAR2 has unspecified behavior. Problem reported by
168 Ralf Wildenhues.
169 * NEWS: Mention this.
171 * Makefile.am: Put only a single '#' into the copyright notice,
172 so that it's also present in the output file. Standardize wording
173 in makefile copyright notices to match GNU coding standards.
174 * bin/Makefile.am: Likewise.
175 * doc/Makefile.am: Likewise.
176 * lib/Makefile.am: Likewise.
177 * lib/freeze.mk: Likewise.
178 * lib/autoconf/Makefile.am: Likewise.
179 * lib/autoscan/Makefile.am: Likewise.
180 * lib/autotest/Makefile.am: Likewise.
181 * lib/m4sugar/Makefile.am: Likewise.
182 * man/Makefile.am: Likewise.
183 * tests/Makefile.am: Likewise.
184 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
185 one-line file.
187 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
189 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
190 in the sed script that mangles the awk script: delete up to the
191 first exclamation mark only.
192 * tests/torture.at (Substitute and define special characters):
193 Test '!' too.
195 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
197 Rewrite config files generation: avoid quadratic growth in
198 the number of substituted variables by using awk instead of sed
199 for the bulk of the substitutions.
200 * NEWS: Mention this.
201 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
202 forbidden in the output (and thus input) file.
203 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
204 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
205 generate just one large awk script for substitutions,
206 eliminating much of the earlier complexity, while adding some
207 new complexity. Only expand the substitution templates at
208 configure time, for smaller configure script size. If
209 _AC_SUBST_FILES are used, test 'awk' for working getline support
210 at config.status time. If absent, interpolate through the
211 shell. The awk script was written with much help
212 from Paolo Bonzini and Paul Eggert.
213 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
214 (_AC_SED_FRAG_NUM): Likewise.
215 (_AC_SUBST_CMDS): Renamed from...
216 (_AC_SED_CMDS): ...this.
217 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
218 * tests/torture.at (Substitute a 2000-byte string): Also
219 substitute a line with 1000 words, and a variable with several
220 long lines.
221 (Substitute and define special characters): Test awk special
222 characters, and put substitution input strings `@foo@' in the
223 output, to test that no recursion happens; test several other
224 combinations from Paolo Bonzini.
226 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
228 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
229 that replaced echo with AS_ECHO where this wasn't necessary.
230 Problem reportd by Ralf Wildenhues.
231 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
232 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
233 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
235 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
237 * lib/freeze.mk (GREP): Removed, no need to initialize this.
239 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
241 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
242 that traditional Awk lacks 3-arg "split". It has it.
243 Mention that FS must be a single character, and a few other
244 99-byte limits of traditional Awk.
245 Mention that if (i in a) doesn't work with traditional Awk.
247 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
249 * tests/autotest.at (BSx641-newline in command):
250 (BS-BS-newline in command, BSx640-newline in command):
251 (Newline-CODE-BS-newline in command):
252 (Single-quote-BS-newline in command):
253 (Single-quote-newline-BS-newline in command):
254 Use printf '%s\n' instead of echo, for portability to hosts
255 where echo interprets backslashes. This will break on hosts
256 that lack printf, but for now let's assume all such hosts
257 are dead (if not, we should get reports of test failures).
259 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
261 'echo' has some portability problems, when given a first argument
262 with a leading '-', or when given any argument containing '\'.
263 Avoid using 'echo' in these cases.
264 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
265 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
266 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
267 * lib/autotest/general.m4 (AT_INIT): Likewise.
268 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
269 argument might be unportable.
270 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
271 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
272 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
273 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
274 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
275 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
276 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
277 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
278 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
279 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
280 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
281 (AC_PROG_MAKE_SET): Likewise.
282 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
283 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
284 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
285 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
286 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
287 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
288 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
289 * bin/autoconf.as: Redo verbose flag implementation, as the old
290 scheme wouldn't work with AS_ECHO.
291 * lib/autotest/general.m4 (AT_INIT): Likewise.
292 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
293 Don't use ECHO_T, since ECHO_N is now reliable.
294 * lib/autotest/general.m4 (AT_INIT): Likewise.
295 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
296 rather than using a here-document to put the script into a file.
297 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
298 use AS_ECHO.
299 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
300 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
301 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
302 bug, but we might as well stop using ECHO_N and ECHO_C internally.
303 * lib/autotest/general.m4 (AT_SETUP): Likewise.
304 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
305 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
306 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
307 operand, as AS_ECHO requires. Avoid double file name expansion.
308 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
309 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
310 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
311 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
312 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
313 Double-quote strings that would otherwise contain M4 comments.
314 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
316 * configure.ac (AC_INIT): Bump to 2.61a.
317 * NEWS: Likewise.
319 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
321 Version 2.61.
323 * configure.ac (AC_INIT): Bump to 2.61.
324 * NEWS: Likewise.
326 * tests/autotest.at (Macro with backslash in a test title):
327 Comment out for now, as this tests neither fails nor passes
328 reliably. Problem reported by Ralf Wildenhues.
330 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
332 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
333 in previous change, which caused test failures.
335 2006-11-16 Stepan Kasal <kasal@ucw.cz>
337 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
338 code for --enable, --disable, --with, and --without to...
339 (_AC_INIT_PARSE_ENABLE): ... a new macro.
340 * doc/autoconf.texi (Package Options):
341 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
343 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>

402 first argument may also contain dots.
404 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
406 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
407 benefit of platforms like Solaris+GCC where it is common to have a
408 non-working g++ installation.
410 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

415 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
416 ./micro-suite.
418 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
420 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
421 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
422 Imported from a similar patch to gnulib by Bruno Haible.
424 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
426 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
427 * doc/autoconf.texi (C Compiler): Document them.
428 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
429 New macros, taken from gnulib.
431 2006-11-07 Paul Eggert <eggert@cs.ucla.edu>
433 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Detect bug in

435 Matthew Woehlke.
437 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
439 * tests/torture.at (Configuring subdirectories): Do not skip
440 Automake 1.10 nor future Automake 11.1 (sic).
442 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
443 and Stepan Kasal <kasal@ucw.cz>
445 Handle special characters in test case titles correctly.
446 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
447 properly.
448 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
449 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
450 argument. Extend to check titles printed by ./micro-suite and
451 ./micro-suite -l and the title in micro-suite.log.
452 (Backquote in a test title,
453 Single-quote in a test title,
454 Double-quote in a test title): Don't expect failure anymore.
455 (Backslash in a test title): Put a non-whitespace character after the
456 backslash so that Bourne shells might actually see it as an escape
457 sequence.
458 (Brackets in a test title,
459 Pound in a test title,
460 Comma in a test title,
461 Quoted Macro in a test title,

464 (Macro with backquote in a test title,
465 Macro with double-quote in a test title,
466 Macro with backslash in a test title): New tests expected to fail.
467 * tests/torture.at (#define header templates): M4-quote this title in
468 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
469 The visible effect was a stray [] in the testsuite output.
471 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
473 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
474 `trap ... 0' inside a function, for AIX sh.
476 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
478 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
479 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
480 5363) simply issues a warning when dividing by zero at compile
481 time. Problem reported by Elias Pipping.
483 2006-10-26 Eric Blake <ebb9@byu.net>
485 * THANKS: Update.
486 * doc/autoconf.texi (Evaluation Macros): Improve the example to
487 show effect on macros that expand with commas.
488 Reported by Joel E. Denny.
490 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
491 Also work with M4 1.4.8.
493 2006-10-25 Paul Eggert <eggert@cs.ucla.edu>

503 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
505 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm
506 needs operands on NetBSD 2.0.2. Problem reported by Bruno Haible.
508 2006-10-24 Stepan Kasal <kasal@ucw.cz>
510 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
512 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
514 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
515 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
516 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
517 reported by Nelson H. F. Beebe for Coreutils 6.4.
519 * tests/tools.at (autoconf --trace: user macros): Remove test
520 for tracing multiline macros, since m4 1.4.7a uses a different
521 way to number lines. Problem reported by Ralf Wildenhues.
523 2006-10-24 Stepan Kasal <kasal@ucw.cz>
525 * bin/autom4te.in (handle_m4): Do not redirect stdin to
526 /dev/null since the heuristics for interactive behaviour was
527 fixed in CVS m4.
529 * bin/autom4te.in: With --force, always refresh the output
530 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
532 * bin/autoconf.as: Fix the verbose message at the end.
534 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

545 * build-aux/texinfo.tex: automake 1.10
547 * NEWS: Remove AC_CACHE_CHECK_INT.
548 * doc/autoconf.texi (Caching Results): Likewise.
549 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
550 AC_CACHE_CHECK_INT, since it's no longer public.
551 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
552 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
554 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
556 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
558 2006-10-19 Eric Blake <ebb9@byu.net>

563 m4_mkstemp.

572 Standards.

580 2006-10-14 Stepan Kasal <kasal@ucw.cz>
582 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
583 looking for special shell characters.
584 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
585 macro defined by AS_VAR_PUSHDEF before passing it as a
586 parameter.
587 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
588 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

597 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
599 (Imported from Automake.)
600 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
601 which incorrectly sets the mode of an existing destination
602 directory. In some cases the unpatched install-sh could do the
603 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
604 system. We hope this is rare in practice, but it's clearly worth
605 fixing. Problem reported by Alex Unleashed in
606 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
607 Also, don't bother to check for -m bugs unless we're using -m;
608 suggested by Stepan Kasal.
610 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
612 Import this change from Automake:
614 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>

616 is enabled by default with gnu and gnits strictness.
617 Report from Bruno Haible.
619 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
620 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
621 gnu and gnits modes.
623 Import this change from Config:
625 2006-09-20 Ben Elliston <bje@gnu.org>
626 * build-aux/config.sub (score, score-*): New.
628 Import this change from Gnulib:
630 2006-09-16 Karl Berry <karl@gnu.org>
631 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
632 to avoid sectioning errors.
634 Import these changes from Texinfo:
636 2006-10-04 Karl Berry <karl@gnu.org>
637 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
638 (\quoteexpand): rename to \rquoteexpand.
639 (\codequoteleft): new def, to look for @set codequotebacktick.
640 (\lquoteexpand, \quoteexpand): new defs.
641 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
642 (\code): must use new \...Char values, since now ` is active.
644 2006-08-26 Karl Berry <karl@gnu.org>
645 * build-aux/texinfo.tex (\textdegree): New command.
647 2006-08-12 Karl Berry <karl@gnu.org>
648 * build-aux/texinfo.tex (error \box0): smaller font.

652 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
654 2006-10-13 Stepan Kasal <kasal@ucw.cz>
656 * doc/autoconf.texi (Autoheader Macros): Warn that the text
657 added to the template can get mangled.
659 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
661 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
662 include the default headers, and redefine obstack_chunk_alloc
663 and obstack_chunk_free. Fixes false failure with glibc.
665 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
667 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
668 for backward compatibility with Libtool 1.5.22. Problem reported
669 by Ralf Wildenhues.
671 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
673 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
674 AC_PROG_CC.
675 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
677 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
679 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
680 the NonStop platform.
681 * doc/autoconf.texi (Posix Variants): Likewise.
682 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
684 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
685 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
686 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
687 Use a better substitute, by inspecting the output of "ls"
688 rather than just using ":".
689 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
690 rather than AS_EXECUTABLE_P, since we needn't worry about
691 non-regular files here.
693 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
694 due to configuration hassles with this. See Tonya Underwood's report
695 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
696 * doc/autoconf.texi (Special Shell Variables): Likewise.
698 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
699 Stepan Kasal <kasal@ucw.cz>
701 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
702 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
704 2006-10-11 Stepan Kasal <kasal@ucw.cz>
706 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
707 initialization which is not inherited through the environment
708 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
709 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
711 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
713 * doc/autoconf.texi (Limitations of Usual Tools): Describe
714 problems with mkdir -p -m.
716 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
718 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
719 comment about ac_cpp_err; it was incorrect, and anyway
720 ac_cpp_err is being removed below.
721 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
722 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
723 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
724 nobody uses it.
725 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
726 with werror_flag and conftest.err and so forth. This is more
727 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
728 and anyway the user shouldn't normally want to see this gorp logged.
729 Problem reported by Ralf Wildenhues.
730 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
731 empty, not 'no', since the rest of the code uses 'test -z'.
733 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
735 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
736 Use a single call to AC_DO_TOKENS rather than multiple, for
737 efficiency.
738 (_AC_LINK_IFELSE): Test that resulting file is executable.
739 Problem reported by mwoehlke in
740 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
742 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
743 than creating a file to use with test -x; this is much faster.
745 2006-10-02 Bruno Haible <bruno@clisp.org>
747 * lib/autom4te.in (Automake-preselections): Add
748 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
750 2006-09-27 Stepan Kasal <kasal@ucw.cz>
752 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
753 standard error, `experr' should be used, not `expout'.
755 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
757 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
758 fseeko testing program twice; just use the earlier result.
759 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
760 Set cache var to 'unknown' (not 'no') if leaving the macro unset
761 still doesn't let the program compile.
762 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
763 failed.
765 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
766 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
767 include it, without including anything else.
768 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
769 expressions.
770 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
772 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
774 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
775 `error.h', and include it, for a `error_at_line' prototype.
776 Use a nonempty format string in the link test.
777 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
778 for a declaration of wait3.
780 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
782 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
783 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
784 can apply to constants too, and that it checks for macro defns.
785 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
786 and simply cast the identifier to void. This handles structure
787 values. Problem reported by Ralf Wildenhues.
788 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
790 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
792 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
793 structure, and function symbols.

798 member.

810 warnings (uninitialized value).
811 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
812 present.
813 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add

843 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
844 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
845 --error-output, to avoid warnings with M4 2.0.
847 2006-09-19 Stepan Kasal <kasal@ucw.cz>
849 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be
850 consistent with _AH_CHECK_FUNCS and _AH_CHECK_HEADERS.
851 * lib/autoconf/headers.m4 (AH_CHECK_HEADERS_DIRENT): Likewise.
853 2006-09-15 Stepan Kasal <kasal@ucw.cz>

858 2006-09-14 Stepan Kasal <kasal@ucw.cz>
860 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
861 mistaken comment: the path has to be relative; do not use
862 the path at runtime.
864 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
866 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the
867 argument to `--prefix' for sub-configure scripts.
868 Pass `--silent' to sub-configure scripts.

870 for both changes.
871 * doc/autoconf.texi (Setting Output Variables): Fix example to
872 not show `--silent' being passed to a `configure' re-run.
874 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
876 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
877 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
878 for the existence of the directory at configure-time. That's
879 too late, anyway. Problem reported by Stefan Seefeld.
881 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
882 7.1.4 /usr/bin/posix/sh described by Tim Rice in
883 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
885 2006-09-11 Stepan Kasal <kasal@ucw.cz>
887 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
888 works with GNU M4 1.4.3 again; make the normalized form
889 match the current m4 message; fix the description.
890 * test/tools.at (autom4te cache): Adapt to the change.
892 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
894 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
895 to catch glibc bug 2821
896 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
898 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
899 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
900 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
901 assume C89.
903 2006-09-08 Stepan Kasal <kasal@ucw.cz>
905 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the
906 preselections ...

918 top_srcdir are not necessarily relative. Problem reported
919 by Dries Kimpe.
921 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
923 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
924 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
925 accept files with extension `.f'. For consistency, also prefer
926 xlf over f77.
927 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
928 from last patch.
930 2006-09-05 Romain Lenglet <rlenglet@users.forge.objectweb.org>

943 before AC_PROG_FC, due to a bug in Autoconf.
945 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
947 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
948 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
949 except the first two arguments are reversed.
950 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
951 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
952 caches nor outputs a diagnostic. Suggested by Bruno Haible.

962 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
963 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
964 programs should use their Gnulib counterparts.
965 * doc/autoconf.texi (Particular Functions): Likewise.
966 (Macro Names, testsuite Invocation): Replace uses of these
967 obsolete macros with uses of non-obsolete macros.

991 simplify the code.
993 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
995 Fix Lex library problem reported to us by Julio Garvia.
996 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
997 for the default, which the user can override.
998 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
999 deal with LEXLIB.
1000 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
1001 didn't work if some values were cached but not others. Test for
1002 broken lex libraries like native ia64-hp-hpux11.22; see
1003 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1004 work around the problem by preferring an empty LEXLIB to -lfl or
1005 -ll. Let the user set LEXLIB='' to indicate no library needed.
1007 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
1008 * README: Likewise.
1009 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

1110 * doc/autoconf.texi (Particular Programs): Mention that
1111 @INSTALL@ and @MKDIR_P@ may vary for different output files.

1134 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
1135 * doc/autoconf.texi (Header Templates, Default Includes):

1150 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
1151 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
1152 this.
1154 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
1156 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1157 problems with arg script text that doesn't end in newline, and

1160 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
1162 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

1172 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1173 --help' should mention that `--version' outputs configuration
1174 settings. Report by Bruno Haible.
1176 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1178 Fix test suite failures reported by Pierre in

1194 less skeptical about "volatile", after discussion with
1195 Bruno Haible on bug-gnulib.
1196 (Limitations of Usual Tools): Warn about sed stripping
1197 leading white space from text. From Bruno Haible.
1199 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1201 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1202 compiler complains about it, even if things works after the
1203 complaint. Problem reported by Peter O'Gorman.
1205 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1206 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1207 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1209 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1211 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

1219 to match M4 1.4.5.
1221 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1223 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1224 under AC_C_VOLATILE.
1225 (Volatile Objects): Be a little less skeptical about what
1226 "volatile" means. Derived from thoughts by Ben Pfaff in
1227 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1229 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1231 * doc/autoconf.texi: Fix some typos.
1233 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1235 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1236 more globally, since the 2006-06-30 patch didn't suffice. Problem
1237 reported by Keith Marshall. Also, don't bother with builddir2,
1238 since it shouldn't be needed any more.
1240 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1242 * doc/autoconf.texi (Generic compiler characteristics):
1243 Document AC_COMPUTE_INT. Fix wrong statements on Default

1257 * NEWS: Document previous change.
1259 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1261 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1262 Require that long long int be at least 64 bits wide. C99 requires
1263 this and enough programs depend on it so we should check for it.
1264 Bruno Haible reports in
1265 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1266 that long long int is 32 bits wide with some nonstandard compilers.
1267 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1269 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1271 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1272 to a nonexistent file, so that we don't have to worry about
1273 a local site configuration that doesn't use /usr/local.
1274 Problem reported by Keith Marshall in
1275 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1277 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1279 * doc/autoconf.texi: Be more consistent about using @acronym with
1280 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1281 quite right (it talked about "OSF/Tru64", even though the
1282 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1283 and it even mentioned "OSF 4"!) and at this point there's little
1284 reason to talk about OSF any more, since it died in 1994.
1285 (Specific Compiler Characteristics): Simplify example of
1286 negative-size array.
1287 (File Descriptors): Reorder to make the text flow better.
1288 Remove joke about "appreciate the various levels"; I didn't get it.
1289 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1290 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1291 (File Descriptors, Limitations of Usual Tools):
1292 Tone down the advice against renaming or removing open files.
1293 (Limitations of Usual Tools): Add a new section, on 'rm'.
1295 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1297 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1298 -lXt in LIBS, idea from Karsten Hopp; this was due since
1299 this change:
1301 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1302 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1303 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1304 (which belong to Xt, not X itself). See Debian bug 327655.
1306 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1308 * configure.ac (AC_INIT): Bump to 2.60a.

1322 quadrigraph correctly in traces.
1324 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1325 Fix typos.
1327 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1328 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1329 not defined.
1330 * doc/autoconf.texi (Changed Directory Variables): New node,
1331 to document the whole `datarootdir' business a bit better.
1332 * NEWS: Update.
1333 * tests/torture.at (datarootdir workaround): Extend test.
1334 Prompted by report by Alexandre Julliard.
1336 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1338 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility

1340 fix reported by Larry Jones.
1342 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1344 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1345 about literal '${datarootdir}' if a definition is found in the
1346 output file.
1348 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1350 * NEWS: Use "M4" rather than "m4" when appropriate.
1351 Problem reported by Eric Blake.
1352 * doc/autoconf.texi: Likewise.
1353 Use @acronym around BSD, GCC, and GNU when appropriate.
1354 (Why GNU M4): Renamed from "Why GNU m4".
1355 (Redefined M4 Macros): Mention that Posix
1356 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1357 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1358 to int.
1360 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1362 * bin/autom4te.in (handle_output): Do not forbid the empty
1363 pattern.
1364 * tests/tools.at (autoconf: the empty token): New test.
1366 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1368 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1369 calls, so that we do not care whether they are LIFO or FIFO;
1370 in the m4_wrap, do not check which diversion is the topmost
1371 one, just check that the stack is balanced at the end.
1372 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1373 base diversion forever--pop the previous diversion before
1374 opening the new one; consequently, remove the m4_wrap call.
1375 * lib/autotest/general.m4 (AT_INIT): Likewise.
1376 * tests/m4sugar.at: Do not use
1377 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1379 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1380 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1382 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1383 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1384 Rework example of m4wrap token-pasting trouble so that it doesn't
1385 care whether it's LIFO or FIFO.
1386 Fix some "contrary to"s that are awkward in English.
1388 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1390 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1391 to `yes' instead of `int$1_t' if the type is found, for more
1392 consistent configure output (where $1 is the number of bits).
1393 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1394 Suggested by Bruno Haible.
1396 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1397 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1398 with system headers. Report by Bruno Haible.
1400 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1402 * config/config.guess, config/config.sub: Sync from upstream.
1404 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1405 in order to avoid picking up an older installed frozen m4sh.m4f.
1406 Besides an outdated shell startup, this could have been created
1407 by an earlier M4 version with incompatible frozen file format.
1409 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1411 * README: Recommend m4 1.4.4 instead of 1.4.3..
1412 * doc/autoconf.texi: Likewise.
1413 (Special Chars in Names): Say that $(.FOO) is portable, as
1414 suggested by Stepan Kasal.
1415 (Installation Directory Variables, Build Directories):
1416 (Automatic Remaking, Subdirectories, Fortran Compiler):
1417 (Making testsuite Scripts, Defining Directories):
1418 Quote variable usages better.
1419 (Making testsuite Scripts): Add clean-local rule to makefile
1420 snippet, by Eric Blake.
1421 (Installation Directory Variables): Fix table item font.
1422 Reword slightly to clarify. Generalize advice about
1423 not using special characters to include all file-related
1424 vars, not just VPATH.
1425 (Special Chars in Variables): Warn about special characters in
1426 $(srcdir) too.
1427 (Assignments): Clarify default-value example as suggested by
1428 Ralf Wildenhues in
1429 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1430 (Special Shell Variables): Note leading ./ or ../, as suggested
1431 by Eric Blake.
1432 (Limitations of Builtins): Under cd, warn about CDPATH.
1433 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1434 Ralf Wildenhues.
1436 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1438 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1439 `@var', for texi2html.
1440 (Systemology): Some more word wrapping, for DVI output.
1441 (autom4te Invocation): The short option for `--melt' is `-M',
1442 not `-m'.
1444 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1446 * doc/autoconf.texi: More formatting and English tweaks,
1447 many suggested by Ralf Wildenhues.
1448 Reword to avoid "@code{...}'s" and the like, since it's ugly
1449 with Emacs info mode. discontents -> woes.
1450 Put a few "will"s back. time stamp -> timestamp.
1451 side-effect -> side effect.
1453 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1455 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1456 Warn about $@ not persisting. Problem reported by Julien Danjou in
1457 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1458 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1459 Mention other special chars, too.
1461 2006-06-14 Eric Blake <ebb9@byu.net>
1463 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1465 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1467 * doc/autoconf.texi: Some systematic minor improvements, as
1468 follows. Use "makefile" when talking about makefiles
1469 generally (which might be named "makefile" or "Makefile" or even
1470 "foo.mk"), "Makefile" when talking about a specific makefile
1471 called "Makefile". This unclutters the text from weird quotes
1472 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1473 values" rather than "@var{foo}s" and similar constructs containing
1474 "}s". Use "Make rules" rather than "Makefile rules". Minor
1475 English-language improvements. Change the prefix "sub-" to "sub"
1476 and "re-" to "re".
1477 Put blank lines around examples more consistently.
1478 Avoid "rather" and "very" as intensifiers.
1479 Avoid "will" as an auxiliary.
1480 (Limitations of Make): Split this node into....
1481 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1482 (Leading _ in Macro Names, Backslash-Newline-Newline):
1483 (Backslash-Newline Comments, Long Lines in Makefiles):
1484 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1485 (obj/ and Make, make -k Status, VPATH and Make):
1486 (VPATH and Double-colon, $< in Explicit Rules):
1487 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1488 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1489 New nodes, resulting from splitup of Limitations of Make.
1490 All cross-references changed. Raise the top node from
1491 a section to a chapter, and all subnodes accordingly.
1492 Redo the introductory wording to match the new organization.
1493 (Installation Directory Variables): Use an example that is
1494 closer to what Autoconf actually does. Mention that VPATH's
1495 value should not contain metacharacters or white space.
1496 (Fortran Compiler): Fix a VPATH bug in an example.
1497 (Leading _ in Macro Names): Mention that this problem is no longer
1498 of practical concern.
1499 (VPATH and Make): Reword the advice to make it clearer
1500 that Autoconf and Automake support VPATH in non-GNU make, but
1501 many packages have bugs in this area.
1502 ($< in Explicit Rules): Refer to Build Directories rather
1503 than using a (non-VPATH-safe) example.
1504 (Automatic Rule Rewriting): Mention the sort of disaster that
1505 can ensue with Solaris-style rule rewriting with VPATH.
1507 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1509 * doc/install.texi (Compilers and Options): Weaken the
1510 suggestion to use GNU make for VPATH builds.
1512 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1513 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1515 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1516 in regular expression.
1518 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1520 * doc/autoconf.texi (Installation Directory Variables):
1521 Drop extra @samp from `@table @samp' item.
1522 (Limitations of Usual Tools): Comment fix.
1523 Do not nest @samp just to point to other table items.
1524 (Writing testsuite.at) <AT_CHECK>: The second argument to
1525 `@dvar' is already @samp'ed.
1526 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1527 do not use @var in the second argument.
1529 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1531 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1532 $as_shell.exe too. Problem reported by Andreas Buening in
1533 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1535 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1537 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1538 `unused variable' compiler warning, for `-Wall -Werror'.
1539 Reported by Jaap Haitsma in
1540 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1542 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1544 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1545 case the compiler dumps core. Problem reported for
1546 OpenServer 5.0.7 by Tim Rice in
1547 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1548 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1549 Likewise.
1551 2006-06-06 Tim Rice <tim@multitalents.net>.
1553 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1554 "ERROR" only shows up in "make check" output if there is an
1555 error.
1557 2006-06-06 Eric Blake <ebb9@byu.net>
1559 * tests/tools.at (automatically allowed tokens): Fix typo.
1561 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1563 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1565 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1566 typically overflows on x86 CPUs, even though the C standard
1567 requires otherwise.
1569 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1571 * configure.ac (AC_INIT): Bump to 2.59e.
1572 * NEWS: Update.
1574 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1576 Version 2.59d.
1578 * config/texinfo.tex: Sync from upstream.
1580 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1581 seen, invoke libtoolize with `--ltdl' argument.
1582 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1583 * NEWS: Update.
1584 Suggested by Eric Blake.
1586 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1588 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1589 reported by Ralf Wildenhues.
1590 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
1592 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1594 * THANKS: Update.
1596 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1598 * doc/autoconf.texi: Modernize some of the references to Solaris.
1600 2006-06-05 Stepan Kasal <kasal@ucw.cz>
1602 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
1603 message issued by AC_REQUIRE.
1604 * tests/m4sugar.at: Check m4_require's error message.
1605 * tests/base.at: Check AC_REQUIRE's error message.
1606 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1607 to...
1608 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1609 AT_CHECK_M4.
1610 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1611 `expout' as the last parameter.
1612 * tests/tools.at: Adapt to the above change.
1614 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1616 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1617 information about race-free implementations of mkdir.
1619 2006-06-04 Eric Blake <ebb9@byu.net>
1621 * bin/autoreconf.in (help): Document M4 environment variable.
1622 * bin/autoconf.as (Usage): Likewise.
1623 * bin/autom4te.in (help): Likewise.
1624 * doc/autoconf.texi (autom4te Invocation): Likewise.
1626 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1628 * NEWS: GNU make now recommended for VPATH builds.
1629 Mention that some macros are now documented to be obsolescent.
1630 * doc/autoconf.texi:
1631 Prefer "current" to "modern" to describe
1632 currently-used (albeit perhaps old-fashioned) hosts.
1633 Mention which ancient features no longer need to be worried about.
1634 setgid -> set-group-ID
1635 setuid -> set-user-ID (these are the Posix terms)
1636 Fix some misuses of "only".
1637 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1638 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1639 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1640 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1641 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
1642 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
1643 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
1644 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1645 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1646 Mention that these macros are obsolescent.
1647 (Installation Directory Variables): shall -> should
1648 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1649 Mention that it's now safe to use 3 and 4.
1650 (Limitations of Usual Tools): cp -r is now specified by Posix.
1651 Omit longwinded and obsolescent discussion of cp -f.
1652 Modernize discussion of expr, ls.
1653 (Limitations of Make): Modernize discussion of VPATH builds.
1654 Mention $? as a workaround in some cases.
1655 * doc/install.texi (Basic Installation):
1656 Mention "./configure; make; make install" first. Be more
1657 specific about why this file is generic. Remove unnecessary
1658 parens. Remove misleading "only". Remove obsolete advice
1659 about csh. Don't say "configure" takes awhile; say it
1660 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1661 and CC=c99 rather than CC=c89, as these are blessed by current
1662 Posix. Recommend GNU make if doing a VPATH build.
1664 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1666 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1667 examples involving shell prompts.
1669 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1670 and Paul Eggert <eggert@cs.ucla.edu>
1672 * doc/autoconf.texi (Here-Documents): Add details about the
1673 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1674 use "here-documents" instead of "here documents".
1676 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1678 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1680 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1682 * doc/autoconf.texi (File System Conventions): Warn about ":"
1683 anywhere in directory names.
1685 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1687 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1688 about quoting the case statement, just in case.
1689 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1690 was fixed in ksh93g; reported by Ralf Wildenhues.
1692 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1694 * doc/autoconf.texi (System Services): Do not document
1695 overriding EXEEXT via ac_cv_exeext=ext.
1696 (Particular Programs) <AC_PROG_MKDIR_P>:
1697 Document that ${MKDIR_P} understands --.
1698 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1699 comment.
1701 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1703 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
1704 argument with leading hyphen. Problem reported by Paul Eggert.
1706 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1708 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
1709 about quoting ac_try: quote all of it, if any of it seems suspicious.
1710 This means we don't have to worry about ${ or sed any more.
1711 Also, double-quote the case statement, to work around misuses via
1712 underquoting as reported by Ralf Wildenhues in
1713 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
1714 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
1715 undocumented and dangerous macro.
1716 Problem reported by Ralf Wildenhues in
1717 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
1719 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1721 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
1722 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
1723 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
1725 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1727 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
1728 since evidently some packages rely on the old, broken behavior.
1729 Problem reported by Ralf Wildenhues in
1730 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
1731 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
1732 pre-2006-05-26 definitions, but leave in the comments that
1733 these macros are dangerous and should not be used.
1734 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
1735 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
1736 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
1737 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
1738 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
1740 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1742 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
1743 the use of 'tr', since this is our only use of 'tr'.
1745 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1746 and Paul Eggert <eggert@cs.ucla.edu>
1748 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
1749 Don't assume 'grep' works on long lines, since AIX grep doesn't.
1751 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1753 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
1754 the output file in the `${datarootdir}' test.
1756 2005-05-28 Stepan Kasal <kasal@ucw.cz>
1757 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1759 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
1760 mention of `datarootdir' in the input file(s), but literal
1761 `${datarootdir}' in the output file, and we haven't warned yet,
1762 then warn as well: the user may have (erroneously) used
1763 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
1764 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
1765 * tests/torture.at (datarootdir workaround): Extend this test.
1766 * NEWS: Update.
1768 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1769 and Paul Eggert <eggert@cs.ucla.edu>
1771 * doc/autoconf.texi (autoheader Invocation): The first argument to
1772 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
1773 alternatives and clear up the language a bit.
1775 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
1777 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
1778 ac_config_guess, ac_config_sub, ac_configure.
1779 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1780 Fix typo that prevented an unnecessary space from being removed.
1781 Problems reported by Ralf Wildenhues in:
1782 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
1784 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1786 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
1787 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
1788 Don't use the term "thread-safe" to talk about mkdir race
1789 conditions, since the problem is more a process than a thread
1790 issue. Problem reported by Stepan Kasal in:
1791 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
1792 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
1793 the test for 'install' more closely. Look at MKDIR_P first.
1794 Look in the PATH, and at /opt/sfw/bin.
1795 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
1796 Don't bother to try mkdir -p, since we already check mkdir --version;
1797 just look at the version number. (There's no easy way to check
1798 for race-free implementations.)
1799 * tests/tools.at (autoconf: subdirectories): Adjust to above
1800 changes, since MKDIR_P now might end in "/mkdir -p".
1802 * doc/autoconf.texi (autoheader Invocation): Mention that the
1803 first arg of AC_DEFINE_UNQUOTED must be a literal.
1804 Problem reported by Ben Pfaff in
1805 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
1807 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
1808 * doc/autoconf.texi (Special Chars in Variables): New section.
1809 (Preset Output Variables): Warn about special chars in CPPFLAGS.
1810 (Installation Directory Variables): Quote $(datadir) better.
1811 (Limitations of Builtins): Describe some of eval's trickiness.
1813 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
1814 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
1815 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
1816 in front of every arg, not just trailing args. Quote apostrophes.
1817 (_AC_EVAL_ECHO): New macro.
1818 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
1819 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
1820 removed.
1821 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
1822 exposed by quoting of eval argument. Put the command on line line
1823 so it logs better.
1824 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
1825 (_AC_PATH_X, AC_PATH_X): Quote more safely.
1826 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
1827 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
1828 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
1829 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
1830 Use eval more safely.
1831 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
1832 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
1833 to be replaced.
1834 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
1835 lines, exposed by quoting of eval argument.
1837 2006-05-26 Stepan Kasal <kasal@ucw.cz>
1838 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1840 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
1841 initialization of `ac_cv_exeext', do not override it if it was
1842 already set, unless it was set to `no', for compatibility with
1843 Autoconf-2.13, and comment this.
1844 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
1845 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
1846 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
1847 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
1848 Document that this test may be overridden by setting
1849 `ac_cv_exeext'.
1851 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1853 Revert these two patches:
1855 2006-04-06 Eric Blake <ebb9@byu.net>
1856 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1857 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1858 2006-04-01.
1860 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1861 Clean up _AC_COMPILER_EXEEXT* macros.
1862 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1863 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1864 ac_file to the name of the default output file and call
1865 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1866 initial `rm' of the candidate files...
1867 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1868 the same list in subsequent `rm' calls, and for the temporary
1869 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1870 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1871 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1872 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1873 no longer needed) by libtool. Make it a cache check.
1874 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1875 copied here by mistake.
1876 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1877 _AC_COMPILER_EXEEXT.
1878 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1879 _AC_COMPILER_OBJEXT directly.
1880 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1882 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1884 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
1885 Fix description of how the buggy `sed' works.
1887 2006-05-25 Noah Misch <noah@cs.caltech.edu>
1889 Sync from Automake:
1891 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
1892 ENOLCK. Only mention `make -j' when applicable. Only raise
1893 fatal errors when `make -j' is involved. Improve error message.
1895 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1897 * doc/autoconf.texi (Here-Documents): We now know more about
1898 the variable expansion in here documents bug.
1899 Thanks to Tim Rice and Stepan Kasal.
1901 * doc/autoconf.texi (Making testsuite Scripts): Add an example
1902 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
1904 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1906 * tests/autotest.at (Multiline command from M4 expansion):
1907 No failure to be expected if the shell quotes newlines in
1908 commands in the `set -x' output. Report by Tim Rice.
1909 * THANKS: Update.
1911 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1913 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
1914 expansion in the here-documents used by config.status, as that
1915 runs afoul of the Korn shell version M-12/28/93d bug described in
1916 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
1917 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
1918 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
1920 2006-05-23 Jim Meyering <jim@meyering.net>
1922 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
1923 Fix typo introduced with 2006-04-02 change. It reversed the sense
1924 of the test.
1926 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1928 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
1929 ac_dB slightly, to save bytes in the script.
1930 Max out at 50 lines, rather than 96; this is more likely
1931 (though not guaranteed) to avoid obscure 'sed' failures.
1933 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1935 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
1936 `tr -d -' as bad option argument. Work around this by deleting
1937 an unrelated character.
1938 Report by Tim Rice <tim@multitalents.net>.
1940 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
1941 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1942 Stepan Kasal <kasal@ucw.cz>
1944 * doc/autoconf.texi (Particular Programs): Do not promise that
1945 we always prefer the GNU version of the program, and that we
1946 search according to PATH; both rules can have exceptions.
1947 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
1948 AC_PROG_SED. Move descriptions of limitations
1949 to the Limitations of Usual Tools section.
1950 (Limitations of Usual Tools) <sed>: Mention script length
1951 limitations with Solaris /usr/ucb/sed.
1952 <grep>: Fix wording for empty alternative. Mention that -c and
1953 -l should not be combined, and that -E and -F should not be
1954 combined.
1956 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1957 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1959 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
1960 limits in Solaris 8 /usr/ucb/sed by testing a long script.
1962 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1964 * doc/autoconf.texi (Defining Symbols): Literal parameter of
1965 AC_DEFINE is now passed to m4_pattern_allow.
1966 * NEWS: Mention that; likewise for AC_SUBST.
1967 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
1968 the parameter to m4_pattern_allow.
1969 * tests/tools.at: Add a check for that.
1971 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1973 * lib/autoconf/status.m4: Fix typos.
1975 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1977 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
1978 only the files that this macro generates.
1980 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1982 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
1983 the HP-UX sed limitation of 99 commands, labels do not count.
1984 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
1985 in the comment.
1986 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
1988 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1990 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1991 Import the following fix from coreutils:
1993 2006-01-13 Jim Meyering <jim@meyering.net>
1995 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
1996 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
1997 not double-quote uses of that variable, to accommodate the rare
1998 case in which getmntent is available in none of the libraries
1999 checked. This happens at least on FreeBSD 5.0.
2001 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2003 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2004 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2005 some other programs unwisely rely on these undocumented vars.
2006 But put in warning comments about them.
2007 Problem reported by Ralf Wildenhues in
2008 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2009 * NEWS: Document that these variables are intended to go away.
2011 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2013 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2014 and set the language to C++ (analogous to the equivalent Fortran
2015 tests).
2017 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2018 * doc/autoconf.texi (C++ Compiler): Document it.
2019 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2020 * NEWS: Update.
2022 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2024 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2025 that caused config.status to generate 100-command sed scripts; the
2026 portable limit is 99.
2028 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2030 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2031 variable `ac_d' instead of `d' to avoid infringing namespace.
2032 Report by Ralf Menzel.
2034 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2036 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2037 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2038 * tests/tools.at (autoconf: subdirectories): New test, taken from
2039 the corresponding problem report by Ralf Wildenhues in:
2040 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2042 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2043 Quote some uses of shell variables if they might suffer unexpected
2044 globbing. This doesn't fix all instances of quoting problems that
2045 I found, just the easy ones that look safe.
2046 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2047 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2048 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2049 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2050 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2051 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2052 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2053 Likewise.
2054 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2055 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2057 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2059 * bin/autoreconf.in ($help): Reword according to the manual.
2060 Suggested by Olly Betts.
2062 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2063 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2065 * bin/autoreconf.in: Pass the directory argument to
2066 `require_configure_ac'. Fix comment.
2067 * tests/torture.at (Configuring subdirectories): Expose this.
2068 Reported by Olly Betts.
2070 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2072 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2073 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2074 Automake as follows:
2076 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2077 `$configure_in' instead of `configure.in', to preserve
2078 directory component.
2080 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2082 * config/config.guess, config/config.sub, config/texinfo.tex,
2083 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2085 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2087 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2088 test for C99 conformance; (bool) 0.5 is an integer constant
2089 expression, but (bool) -0.5 is not. Problem reported by Fedor
2090 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2092 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2094 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2095 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2096 Warn about obsolete install-sh files. Remove stray sentence
2097 fragment and fix cross reference.
2098 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2099 install -d; this undoes the 2006-05-10 change.
2100 (MKDIR_P): Mark with AN_MAKEVAR.
2101 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2102 that we don't require $INSTALL to be thread-safe. Move comments
2103 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2104 of AC_PROG_INSTALL. Output a message saying that we're checking
2105 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2106 MKDIR_P instead of AC_SUBST.
2107 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2108 Special magic for MKDIR_P, too.
2109 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2110 a dnl.
2111 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2113 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2115 Sync from Automake, as follows:
2117 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2118 * config/install-sh: Initialize IFS, so field splitting isn't
2119 turned off later.
2120 * config/mkinstalldirs: Likewise.
2121 * config/missing: Remove superfluous quotes. Replace all uses of
2122 `[' by `test', for consistency, and for..
2123 * config/missing (sed_minuso, sed_output): New variables.
2124 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2125 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2126 Fixes `missing' to detect `--output' for help2man. Fixes
2127 PR automake/483. Report by Dennis J. Linse.
2128 (autom4te): Document in `missing --help'.
2130 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2132 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2133 * config/install-sh: Don't use 'path' to talk about file names,
2134 as per GNU coding standards. Close a race condition reported by Ralf
2135 Wildenhues and Stepan Kasal. There is still a race condition
2136 on hosts that predate Posix 1003.1-1992, but we can't help this.
2137 Don't mishandle weird characters like space on pre-Posix hosts.
2138 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2139 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2140 AC_PROG_MKDIR_P from AS_MKDIR_P.
2141 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2142 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2143 earlier editions are not (including Automake 1.8.3).
2144 Do not suggest mkinstalldirs for thread-safety.
2145 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2146 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2147 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2148 presence of special characters and race conditions.
2149 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2150 in Autoconf's name space.
2152 2006-05-10 Bruno Haible <bruno@clisp.org>
2153 and Paul Eggert <eggert@cs.ucla.edu>
2155 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2156 from Automake with minor changes.
2157 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2159 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2161 * config/install-sh: Update to Automake CVS version, as follows:
2162 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2163 * lib/install-sh: Simplify the expr implementation of dirname.
2164 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2165 * lib/install-sh: Handle --, and diagnose unknown options.
2167 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2169 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2170 `./autom4te' to create `./testsuite', since the `all' target
2171 will ensure its presence, but `installcheck' should not create
2172 the uninstalled wrappers.
2174 * tests/torture.at (Unusual Automake input files): Skip if we
2175 detect automake < 1.8.
2177 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2179 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2180 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2181 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2182 * NEWS: Update.
2184 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2186 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2187 munge (multiple) white space and other oddities.
2188 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2189 single quotes in variable assignment.
2190 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2191 and similar failures by adding multiple spaces, tabs, and other
2192 special characters.
2193 Report and different test suggested by Francesco Romani
2194 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2196 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2197 single quotes, we only need to search for single quotes; this
2198 both simplifies the search pattern, and makes us less
2199 susceptible to `echo' variations for arguments not containing
2200 single quotes.
2201 (_AC_ARG_VAR_VALIDATE): Likewise.
2203 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2205 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2206 `$*' and IFS concatenation issue with traditional shells and
2207 bash-2.04. Report by Seanster@Seanster.com.
2209 2006-05-03 Bruno Haible <bruno@clisp.org>
2211 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2212 precisely which Mac OS X versions have the od problem.
2214 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2216 * doc/autoconf.texi: Use @option systematically.
2218 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2219 and Bruno Haible <bruno@clisp.org>
2221 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2222 about 'od'.
2223 (Integer Overflow): Mention the special case of integer division
2224 overflow.
2226 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2228 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2229 traditional shells like the Solaris one that do not use the
2230 first IFS character for assembling `$*'.
2231 Prompted by a related report from autoconf_bug@nro.ca.
2233 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2234 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2236 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2237 Mention more problems with the -e option.
2239 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2241 * NEWS: Typo.
2242 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2244 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2245 in URLs to improve DVI formatted output (requires texinfo 4.6).
2246 (System Services, Systemology, Shellology): Likewise.
2247 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2248 output.
2250 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2251 continuous text.
2252 (Runtime): Fix macro argument names to match description:
2253 `action-if-found' -> `action-if-true' and similarly.
2254 (Obsolete Macros): Likewise.

2256 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2257 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2259 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2261 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2263 * ChangeLog: Typo.
2264 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2265 DVI output.
2267 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2269 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
2270 /bin/sh set unsorted output.
2271 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
2272 * tests/local.at: Likewise.
2274 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
2276 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2277 (Integer Overflow, Null Pointers, Buffer Overruns):
2278 (Floating Point Portability, Exiting Portably): New sections.
2279 (Writing Test Programs): Fix some langauge. Recommend exiting
2280 with status 1, not merely nonzero. Clarify exit declaration.
2281 (Run Time): Move C exit status stuff to new Exiting Portably section.
2282 (Systemology): Mention Posix and levenez. Update v7 reference.
2283 (Portable Shell): Mention the Posix shell.
2285 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2287 * bin/autoconf.as (me): Replace by as_me.
2289 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2291 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2292 since as_me isn't set yet.
2294 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2296 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2297 a few minor bugs in this area.
2299 * doc/autoconf.texi (Programming in M4sh): Comment out the
2300 documentation of AS_BASENAME, for now.
2301 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2302 (Limitations of Builtins) <basename>: Do not refer to
2303 AS_BASENAME.
2304 * bin/autoconf.as (me): Don't use AS_BASENAME.
2305 (dir): Remove the unused variable.
2306 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2307 AS_DETECT_REQUIRED. All uses changed.
2308 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
2309 All uses changed.
2310 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
2311 (AS_BASENAME): Use "basename --" to protect against leading "-".
2312 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
2313 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2314 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".

2317 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2318 (AS_DIRNAME): Use "dirname --".
2320 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2322 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2323 of "run time" and "run-time" changed to "runtime", for consistency.
2324 * lib/autoconf/fortran.m4: Likewise (in comment).
2325 * lib/autoconf/functions.m4: Likewise.
2326 * lib/autoconf/general.m4: Likewise.
2327 * lib/autoconf/headers.m4: Likewise.
2329 * doc/autoconf.texi (Run Time): Document the exit status situation
2330 with more accuracy and detail.
2332 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2334 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2335 Archive is not officially `GNU' any more. Update URL.
2336 (Defining Directories): Likewise
2337 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2339 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2341 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2342 newline from the `trap' code to finish `config.log'; the NetBSD
2343 /bin/sh resets the exit status after an empty command, as
2344 documented in doc/autoconf.texi.
2345 Reported by Dalibor Topic <robilad@kaffe.org>.
2347 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2349 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2350 Suggested by Bruno Haible.
2352 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2354 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2355 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2356 Instead, just list the shells that we know work.
2357 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2358 changed. Be more cautious about the _cv_ variable.
2359 * tests/tools.at (Syntax of the shell scripts): Check the
2360 _cv_ variable once, at first, to avoid an internal autoconf error
2361 when sh -n does not work.
2363 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2365 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2367 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2369 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2370 use ">&-" since we're only 99.999% sure that this is portable,
2371 and since the MinGW bug is fixed in a different way.
2372 * lib/autotest/general.m4 (AT_INIT): Likewise.
2374 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2376 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2377 before opening config.log, to avoid hitting a bug on MinGW.
2379 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2381 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2382 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2383 This works around a MinGW bug reported by Eric Paire.
2384 Make sure that all writes to the log file append to it,
2385 rather than possibly losing data.
2386 * lib/autotest/general.m4 (AT_INIT): Likewise.
2388 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2390 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2391 description.
2393 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2395 * NEWS: Update.
2397 * configure.ac (AC_INIT): Bump to 2.59d.
2399 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2401 Version 2.59c.
2403 * Makefile.maint (news-date-check): Do not require a leading `*'
2404 before the release date in NEWS.
2406 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2407 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2409 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2410 the instantiated file do not contain the string 'datarootdir'
2411 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2412 @mandir@, replace the reference '${datarootdir}' by the value.
2413 * tests/torture.at (datarootdir workaround): New test.
2414 * NEWS: Advertise this temporary fixup.
2415 Based on a patch by Bruno Haible, reported and analyzed by
2416 Paul Eggert and Noah Misch.
2418 2006-04-12 Eric Blake <ebb9@byu.net>
2420 * tests/autotest.at (Debugging a failed test): Fix comment.
2422 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2424 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2425 all the changes since 2006-04-07.
2427 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2429 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2430 succeeded, but `ln -s file dir' failed, take care to remove the
2431 leftover target before the next test, to prevent its spurious
2432 failure; also make sure `ln file dir' works before selecting it.
2433 Thanks to Keith Marshall for pointing this out.
2434 * THANKS: Update.
2436 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2437 assignments in `at_debug_args', so that we put them correctly
2438 in the `run' script.
2439 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2440 Reported by Eric Blake.
2442 2006-04-11 Eric Blake <ebb9@byu.net>
2444 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2445 top-level tests after micro-suite has been run. Used in...
2446 (Debugging a successful test, Debugging script and environment),
2447 (Debugging a failed test): ...these new tests. The first of these
2448 is fixed by...
2449 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2450 macro, split out from...
2451 (AT_INIT): ...here, so that using -d also generates a run script.
2452 Document that -d inhibits top-level logging.
2453 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2454 inhibits top-level logging; debug scripts are created.
2456 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2457 check.
2458 * tests/autotest.at (Empty test, Empty check): New test to check it.
2460 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2461 from gcc.
2463 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2465 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2466 the files if a problem appears. Make the empty *.at files
2467 read-only, too. Proposed by Ralf Wildenhues.
2469 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2471 * config/Makefile.am: Add comment to force updated Makefile.in.
2473 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2474 space only patch to this file, this patch causes the Makefile.in
2475 files that include freeze.mk to be updated, and thus have a
2476 newer time stamp again, which in turn makes a pristine CVS
2477 checkout have correct time stamps.
2479 * Makefile.maint (cvs-sv): New macro, to be used..
2480 (config.guess-url_prefix, config.sub-url_prefix)
2481 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2482 point to CVS text checkout of Gnulib files.
2483 (copyright-check): Bump current year.
2484 (announcement): Do not hard-wire `./announce-gen'.
2485 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2486 correctly.
2487 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2488 `chmod +x'.
2489 (wget_files): Update config.guess, config.sub, texinfo.tex by
2490 `wget-update', now that their URLs work again.
2492 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2494 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2495 Problem noted by Paul D. Smith.
2497 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2499 * doc/autoconf.texi: Remove unused words from word list.
2500 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2501 .x-sc_trailing_space: New files.
2503 * doc/standards.texi: Sync from gnulib.
2505 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2506 `LIBOBJDIR' as experimental.
2508 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2509 with a target directory; it's internally implemented as `cp'
2510 anyway, but since Autoconf advertises the possibility to use
2511 a target directory when LN_S is `ln -s', we need to find out.
2512 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2513 analyzed by Keith Marshall <keith.marshall@total.com>.
2515 * THANKS: Update.
2517 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2519 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2520 confdefs.h as-is. In general, if it has backslash-newline or the
2521 like, then it doesn't work either to sort or to remove empty
2522 lines.
2524 2006-04-09 Stepan Kasal <kasal@ucw.cz>
2526 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
2528 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
2530 * lib/autom4te.in (Automake-preselections): Preselect
2531 _AM_SUBST_NOTMAKE.
2533 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2535 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2536 apostrophe within a single-quoted string, as this is the usual
2537 tradition and is easier to read than '"'"'. Don't rely on the
2538 shell treating "$/" like '$/'. Use a more-consistent indenting
2539 style for the trap.
2541 2006-04-09 Eric Blake <ebb9@byu.net>
2543 * tests/autotest.at (Backquote command substitution),
2544 (Multiline backquote command substitution): Remove mistaken
2545 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2546 applied...
2547 (Parenthetical command substitution, Multiline parenthetical
2548 command substitution): here.
2550 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2552 Import macros from gnulib (often changing their name).
2554 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
2555 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
2556 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

2566 (Pointers): Add Gnulib URL.
2567 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
2568 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
2569 Gnulib section.
2570 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
2571 suggest a #define rather than a typedef for _Bool, and mention
2572 Gnulib rather than trying to substitute stdbool code.
2573 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
2574 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
2575 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
2576 AC_STRUCT_DIRENT_D_TYPE.
2577 (Particular Types): Mention stdint.h and inttypes.h as standard
2578 headers too.
2579 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
2580 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
2581 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
2582 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
2583 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
2584 (C Compiler): Move AC_C_LONG_DOUBLE to ...
2585 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
2586 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
2587 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
2588 (Coding Style). Don't mention m4_expand_once.
2589 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
2590 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
2591 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
2592 (AC_CHECK_FUNCS): Use it.
2593 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
2594 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
2595 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
2596 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
2597 (AC_HEADER_ASSERT): New macro.
2598 (AC_HEADER_STDBOOL): Don't assume "#error" works.
2599 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
2600 Catch a bug in an HP-UX C compiler.
2601 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
2602 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
2603 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):

2606 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
2607 New macros.
2609 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
2610 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
2612 2006-04-08 Stepan Kasal <kasal@ucw.cz>
2614 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
2615 of the warning introduced by the 2001-08-28 change.
2617 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
2618 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2620 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
2621 variables shall be overriden by the cache.
2622 * tests/torture.at (AC_ARG_VAR): Test also with a first value
2623 that contains braces.
2625 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2627 Revert the patch from 2006-04-01 and only improve
2628 _AS_DETECT_BETTER_SHELL:
2630 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2631 skip nonexistent directories.
2632 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2633 only shell candidates which exist.
2634 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2635 * lib/autotest/general.m4 (AT_INIT): No need to give three
2636 parameters to _AS_PATH_WALK.
2638 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2639 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2641 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2642 distinguish m4sugar macros.
2643 * tests/tools.at (autoupdating with aclocal and m4_include):
2644 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2645 test case by Noah Misch <noah@cs.caltech.edu>.
2647 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2649 Revert my change from 2006-03-17, in other words:
2650 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
2651 and DUALCASE=1.
2652 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
2653 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
2654 it is set.
2656 2006-04-07 Eric Blake <ebb9@byu.net>
2658 * doc/autoconf.texi (Programming in M4sh): Document that
2659 AS_MKDIR_P exits the script on failure.
2660 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2662 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2664 * config/elisp-comp, config/install-sh, config/mdate-sh,
2665 config/missing, config/mkinstalldirs: Sync from Automake.
2667 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
2668 from Automake.
2670 * doc/make-stds.texi: Sync from gnulib.
2672 2006-04-06 Eric Blake <ebb9@byu.net>
2674 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2675 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2676 2006-04-01.
2678 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
2679 Eric Blake <ebb9@byu.net>,
2680 Paul Eggert <eggert@cs.ucla.edu>,
2681 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2683 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2684 whether `set' quotes correctly: redirect stderr of the tested
2685 `set', and use a subshell, for Ultrix; use `sed' instead of
2686 `grep' for zsh `set' which may write binary output; match only
2687 at the beginning of a line, to avoid false positives.
2688 In order to avoid false positives by unrelated variables with
2689 multiline content, put the dump algorithm in a subshell and
2690 unset all variables containing newlines (except some which are
2691 special to the shell). Warn about cache variables that are
2692 unset.
2694 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2696 * config/config.guess, config/config.sub, config/texinfo.tex:
2697 Sync from upstream.
2699 * tests/mktests.sh: Reword comments.
2701 * tests/mktests.sh: Only skip internal macros starting with

2898 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2899 initial `rm' of the candidate files...
2900 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2901 the same list in subsequent `rm' calls, and for the temporary

2904 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2905 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2906 no longer needed) by libtool. Make it a cache check.
2907 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2908 copied here by mistake.
2909 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2910 _AC_COMPILER_EXEEXT.

2947 subordinate tools.
2948 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
2949 * doc/autoconf.texi (autoreconf Invocation): Document it.
2951 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

3616 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Initialize
3617 `tmp' to avoid file removal race.
3619 2005-11-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3621 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
3622 ac_clean_files and LIBOBJS.
3624 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3626 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
3627 Factor functionality to..
3628 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
3629 `AC_SUBST($1)' in the public version.
3630 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
3631 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
3632 ac_pt_* variables.
3634 2005-11-01 Stepan Kasal <kasal@ucw.cz>
3636 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
3637 filesystems.
3639 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3641 * NEWS: Move AH_HEADER mention to right place.
3643 2005-10-27 Stepan Kasal <kasal@ucw.cz>
3645 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
3646 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3648 2005-10-25 Stepan Kasal <kasal@ucw.cz>
3650 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
3651 conftst2.$ac_objext.
3652 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3654 2005-10-24 Stepan Kasal <kasal@ucw.cz>
3656 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
3657 conftest.o, to see whether the compiler really obeys; rm the object
3658 file before and after the test and register it with ac_clean_files.
3659 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3661 2005-10-21 Stepan Kasal <kasal@ucw.cz>
3663 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
3664 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
3665 code so that the most common case requires less forks.
3667 2005-10-20 Stepan Kasal <kasal@ucw.cz>
3669 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
3670 not portable; thanks to Paul Eggert and Alexandre.
3672 * NEWS: Fix an old typo.
3674 2005-10-20 Jim Meyering <jim@meyering.net>
3676 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
3677 the latter'', in two places.
3679 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
3681 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
3682 AC_LANG_PROGRAM, fixing a typo. Don't give details about
3683 the inner workings of AC_LANG_FUNC_LINK_TRY.
3684 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
3685 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
3686 by the function rather than ignoring it.
3687 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
3688 comparing its address. Intel's interprocedural optimization was
3689 outsmarting the old heuristic. Problem reported by
3690 Mikulas Patocka.
3692 2005-10-19 Stepan Kasal <kasal@ucw.cz>
3694 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
3696 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
3698 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

3701 2005-10-04 Stepan Kasal <kasal@ucw.cz>
3703 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
3704 before removing it (chmod -R u+rwx); there are three instances of this.
3706 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3707 Stepan Kasal <kasal@ucw.cz>
3709 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
3710 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
3711 make its content writable before removing it. Remove an errorneous
3712 comment from the end, where the logs of the failed tests are copied
3713 to the main log file.
3715 2005-09-27 Stepan Kasal <kasal@ucw.cz>
3717 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
3718 in case the computer is too quick. Double quote the configure.ac
3719 snippets.
3721 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
3722 problems if the testsuite were running too fast.
3724 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3726 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3727 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3728 (which belong to Xt, not X itself). See Debian bug 327655.
3729 * NEWS: Mention this.
3731 2005-09-07 Stepan Kasal <kasal@ucw.cz>
3733 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
3735 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
3737 * config/move-if-change: Don't output "$2 is unchanged";
3738 suggested by Ben Elliston. Handle weird characters correctly.
3740 2005-09-06 Stepan Kasal <kasal@ucw.cz>
3742 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
3743 calls, so that the final expansion of this macro is shorter.
3744 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
3745 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
3746 the cleanup there. Use AS_VAR_* macros, to be more general.
3747 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
3749 * lib/autoconf/general.m4: Use AS_IF where appropriate.
3751 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
3753 2005-09-01 Stepan Kasal <kasal@ucw.cz>
3755 * doc/autoconf.texi (Configuration Headers): Add an index entry
3756 for AH_HEADER.
3758 2005-08-26 Pavel Roskin <proski@gnu.org>
3760 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
3761 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
3762 running xmkmf.
3764 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
3766 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3767 The previous patch didn't work, so try a better one.
3769 2005-08-26 Stepan Kasal <kasal@ucw.cz>
3771 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
3772 in the example. Reported by Bruno Haible.
3773 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
3774 "if $undefined_var;" succeeds with my shell.
3776 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
3777 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
3778 but change the m4_divert_text to m4_divert_once.
3780 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
3782 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3783 Work around bug in Solaris /usr/xpg4/bin/awk.
3784 The bug is present in at least Solaris 8 through 10.
3786 2005-08-24 Stepan Kasal <kasal@ucw.cz>
3788 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
3789 some evil values and relying on the fact that $* concatenates the
3790 parameters by the first character from IFS.
3792 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3793 Stepan Kasal <kasal@ucw.cz>
3795 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
3796 first header appears, define AH_HEADER.
3797 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
3798 Update limitations about when to call AC_CONFIG_HEADERS.
3799 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
3800 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
3801 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
3802 ``Configuration Actions''; fix their index entries.
3804 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
3805 options correctly. Process N-M as M-N if M is smaller than N.
3806 Process ranges correctly so that N-N will run only N.
3807 Sort and uniquify the tests that will be run. If there is more
3808 than one test, reinsert the banners for the tests.
3809 * tests/autotest.at (Keywords): Unmark XFAIL.
3811 2005-08-23 Stepan Kasal <kasal@ucw.cz>
3813 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
3814 before passing the macro name to AH_TEMPLATE.
3816 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
3817 now opens log after option processing; in particular, --version
3818 and --help do not touch config.log.
3820 * Makefile.maint: Revert the change from 2005-08-12.
3822 2005-08-22 Stepan Kasal <kasal@ucw.cz>
3824 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
3825 common code to...
3826 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
3828 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3830 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
3831 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
3832 Language cleanup.
3834 * doc/autoconf.texi (Defining Symbols, Changed Results):
3835 Prepend to LIBS, not append, in examples.
3837 2005-08-16 Stepan Kasal <kasal@ucw.cz>
3839 When building in place, set srcdir="."; suggested by Tim Van Holder.
3841 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
3842 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
3843 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
3844 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
3845 does not mean "no --srcdir option".
3847 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3849 * tests/autoscan.at (autoscan): New file.
3850 * tests/suite.at: Use it.
3851 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
3852 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
3854 * tests/autotest.at (Keywords): Test keywords combinations.
3856 2005-08-12 Stepan Kasal <kasal@ucw.cz>
3858 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
3859 add "2>&1"; gzip 1.2.4 prints help on stderr.
3861 2005-07-27 Stepan Kasal <kasal@ucw.cz>
3863 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
3864 was pushdef'ed twice while popped only once. Push it only once.
3865 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
3867 2005-07-26 Stepan Kasal <kasal@ucw.cz>
3869 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

3874 * Makefile.maint: Update from Bison.
3876 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
3877 "<tab>" in comment, so that the point is understandable.
3879 2005-07-25 Stepan Kasal <kasal@ucw.cz>
3881 Rewrite substantial part of lib/autoconf/status.m4.
3882 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
3883 and CONFIG_COMMANDS are not processed in four separate loops.
3884 Instead, there is one main loop. This alows that the common code
3885 is expanded only once, thus config.status (and configure) is smaller.
3887 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
3888 the AC_LIST_FILES and cousins macros are no longer used.
3890 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
3891 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
3892 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
3893 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
3894 contain the initialization, nor the for loop, nor the associated
3895 commands; all these go to ...
3896 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
3897 _AC_OUTPUT_CONFIG_STATUS.
3898 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
3899 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
3900 (_AC_OUTPUT_FILE): The creation of the sed script ...
3901 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
3902 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
3903 _AC_OUTPUT_MAIN_LOOP.
3904 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
3905 _AC_CONFIG_COMMANDS): Use ...
3906 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
3907 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
3908 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
3909 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
3910 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
3911 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
3912 ... new macros.
3913 (_AC_CONFIG_UNIQUE): Update.
3914 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
3915 Replaced by this ...
3916 (_AC_LIST_TAGS): ... new common macro.
3917 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
3918 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
3919 (_AC_LIST_TAG_COMMANDS): ... new common macro.
3920 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
3921 this didn't belong to the `config commands' section.
3922 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
3923 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
3924 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
3925 to the `config commands' section either.
3926 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
3927 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
3929 ... and many changes to the comments nearby.
3931 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
3932 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
3933 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
3934 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
3935 (#define header templates): The comment at the top of the generated
3936 header now includes the name(s) of the source file(s).
3938 Several unrelated small changes:
3940 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
3941 parameter to AC_DIAGNOSE.
3942 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
3943 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
3944 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
3945 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
3946 with AU::AC_OUTPUT.
3947 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
3948 in AC_OUTPUT doesn't double-quote it either.
3949 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
3950 parameters.
3952 2005-07-10 Stepan Kasal <kasal@ucw.cz>
3954 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
3955 versions of Portland Group compiler produce single- and double-quoted
3956 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
3957 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
3959 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3961 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3962 This is a corrected version of yesterday's patch.
3964 2005-07-07 Stepan Kasal <kasal@ucw.cz>
3966 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
3967 path, too; insert a "===" to emphasize the line.
3969 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
3970 ac_cv_build_alias to ac_build_alias.
3971 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
3973 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
3974 change eliminates it. Problem reported by Alexandre Duret-Lutz.
3975 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
3976 (AC_ARG_VAR): ... here.
3977 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
3978 target_alias.
3980 Keep a list of all precious variables and process them with one simple
3981 for loop, instead of expanding all commands, or, OTOH, complicated
3982 processing of output of "set".
3983 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
3984 variable names in new macro...
3985 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
3986 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
3987 a loop to assign all ac_env_* and ac_cv_env_* variables.
3988 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
3989 to INIT_PREPARE.
3990 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
3991 its value to shell variable ac_precious_vars and call
3992 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
3993 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
3994 _AC_ARG_VAR_VALIDATE.
3996 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
3997 and the AC_SUBSTs ...
3998 (AC_INIT): ... here.
4000 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
4001 the ac_subst_files section in config.log.
4003 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.

4012 Fix problems reported by Nicolas Joly.
4013 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
4014 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4015 They are generated by the Tru64 v5.1B shell.
4017 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4019 Fix my changes from 2005-07-01; reported by Noah Misch.
4020 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
4021 description, the macro now accepts only a single tag.
4022 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
4024 Fix cases when the varsions of Autoconf and Autotest don't match.
4025 Reported by Noah Misch.
4026 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
4027 at_top_builddir, for compatibility with older autotest.
4028 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
4029 is not set, use at_top_builddir, for compatibility with older
4030 versions of autoconf.
4032 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4034 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
4035 Problem reported by Patrick Welche.
4037 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4039 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4040 sed substitution command, so that we allow | in program prefixes
4041 and program suffixes. (& is a problem anyway; we're not fixing
4042 that here.)
4043 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4044 configure_input, top_builddir, srcdir, etc.
4045 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4046 PATH_SEPARATOR in AUTOTEST_PATH.
4048 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
4050 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
4051 for loop over config.site files using `set', to allow
4052 directory names containing IFS characters.
4054 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
4056 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
4057 directories with weird names. Apparently some people like living
4058 on the edge. However, improve the test that "pwd" actually does
4059 report a name for the working directory.
4060 * NEWS: Remove the claim that we test for funny chars in dir names.
4062 2005-07-01 Stepan Kasal <kasal@ucw.cz>
4064 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
4065 replaced ...

4076 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
4078 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
4079 document to output the default config_* lists to config.status.
4080 Don't recognize option --file, if the functionality is not there.
4081 Likewise for --header; moreover, recognize --he and --h as shortcuts
4082 for --help in that case.
4084 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4085 matches the order of execution. No code changed.

4107 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4108 (AC_SUBST): Call it.
4109 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4110 the directory specific variables; but don't call it for configure_input.
4112 2005-06-28 Derek Price <derek@ximbiot.com>
4114 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4115 addition.
4117 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4119 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4120 directory have inherent problems with special characters like spaces,
4121 due to limitations in Make syntax. Problem reported by Alexandre
4122 Duret-Lutz.
4123 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
4124 Also, fix Tru64 porting problem with shell patterns,

4136 from Justace Clutter.
4137 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4138 variable into diagnostic. Make the diagnostic an error, not a warning,
4139 because we really don't support spaces and suchlike in dir names.
4140 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4141 Don't worry about backslashes in srcdir; it can't happen now.
4142 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
4143 Simplify ac_optarg handling.
4144 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

4154 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
4155 that '\|' is not allowed in BREs; recommend using newline separated
4156 list of patterns instead of multiple -e options.
4158 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
4160 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

4166 2005-06-21 Stepan Kasal <kasal@ucw.cz>
4168 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4169 b, t, r, w commands require single space, while : cannot have any.
4170 (Special Shell Variables): Fix sed code this in the example.
4171 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4172 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4174 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4175 expand to the empty list. Don't use two pairs of m4_changequote,
4176 it's not necessary.
4178 2005-06-20 Derek Price <derek@ximbiot.com>
4180 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
4182 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
4184 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4185 * doc/autoconf.texi:
4186 Don't mention Solaris versions so much, if a
4187 problem is common to all extant versions of Solaris. Say "SunOS
4188 4" instead of "SunOS" for SunOS 4.
4189 (awk): Mention more of the limitations of traditional Awk.
4190 (cat): Don't talk about cat -v.
4192 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
4194 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
4195 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

4197 to be compatible with glibc strverscmp.
4198 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4200 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4201 on Mac OS X 10.4 reported by Peter O'Gorman in:
4202 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
4203 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
4204 Use shell builtins rather than 'expr', to work around expr bug.
4206 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4208 * doc/autoconf.texi: "filesystem" -> "file system".
4209 "behaviour" -> "behavior".

4211 * lib/autoconf/general.m4: Omit blank after ":" sed command,
4212 as per POSIX.
4213 * lib/m4sugar/m4sh.m4: Likewise.
4214 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
4215 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
4217 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4218 (.x.1): Ignore the time stamp in the .TH line when deciding whether
4219 to update the man page. That way, we don't have to check in new
4220 man pages every month.
4222 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
4223 quotes and backslashes. Patch from Derek Price.

4227 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &
4228 AS_TR_SH.
4230 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
4232 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4233 -u, since it outputs chatter if the input files are the same.
4234 Problem reported by Ralf Menzel.
4236 2005-06-08 Derek Price <derek@ximbiot.com>
4238 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4239 renaming them since they are about to be redefined anyhow.
4241 2005-06-08 Derek Price <derek@ximbiot.com>
4243 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4244 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4245 Move m4_undefine to alphabetical order.
4247 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4249 * README: Recommend GNU M4 1.4.3 or later.
4250 * doc/autoconf.texi (Introduction): Likewise.
4251 Reword to avoid some formatting glitches.
4252 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4253 Clarify explanation of HP compiler bug.
4254 Redo example output tp match current CVS snapshot.
4255 Use @example.org in email addresses when the examples
4256 might get inadvertently cut-and-pasted into user code.
4257 Remove example of autom4te usage that doesn't seem to work now.
4258 Use modern AC_INIT (except when the example is meant to be
4259 shown with Autoconf 2.13).
4260 Update ksh info for Solaris 9 and later.
4261 KB -> kB.
4262 Modernize description of Automake versions a bit.
4263 Don't claim a future version of Autoconf is near.
4264 * doc/install.texi: Reword to avoid some formatting glitches.
4266 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4269 follows its own advice about quoting better.
4270 Reword to avoid some formatting glitches.
4271 * doc/installt.exi: Reword to avoid some formatting glitches.
4273 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4274 Tru64 ksh pattern matching bug. Reported against Libtool by
4275 Albert Chin <libtool@mlists.thewrittenword.com> and
4276 Nicolas Joly <njoly@pasteur.fr>.
4278 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4280 m4_cdr of one-member list was [[]] (one-member list containing an
4281 empty string) instead of [] (an empty list. Callers were skewed to
4282 match this misbehaviour. As a consequence of this:
4283 - m4_foreach([x], [], [foo]) expanded to `foo', while
4284 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4285 This bug has been fixed:
4287 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4288 expand to an empty string; print error msg if called without
4289 an argument list.
4290 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4291 misbehaviour; handle [] and [[]] correctly.
4293 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4295 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

4297 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4299 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4301 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4302 swallow records with more than 99 fields.
4303 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4304 parse the long line.
4306 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4308 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4309 swallow literals longer than 399. Reported by Ralf Wildenhues.
4310 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4311 to workaround this limitation.
4313 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4315 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4316 to gfortran, and make these the first two compiler names
4317 checked (following the general autoconf preference for gcc).
4319 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4321 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4322 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4323 (testsuite): Make sure autotest.m4f is up-to-date before using it.
4325 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
4327 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4328 expression of unbounded size when processing the --list
4329 option. This runs afoul of a limit of 399 bytes per regular
4330 expression on AIX. Problem reported by Ralf Wildenhues.
4332 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

4335 * doc/autoconf.texi (Particular Headers): Reword example
4336 for multiline stdbool replacement.
4337 (Setting Output Variables): Reword text a bit. Don't
4338 give all the details about |#_!!_#|.
4339 Reword description of line replacement.
4341 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4343 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4344 now contain newlines, and substituted files must be referenced on
4345 a line alone; the sed scripts to substitute them are now very
4346 different.
4347 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4348 commands can be put in a sed script portably.
4349 * doc/autoconf.texi (Setting Output Variables): Document above
4350 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4351 use of multiline substitution.

4361 * tests/local.at: Don't attempt to check for negated character
4362 classes in shell scripts. The test was too brittle.
4364 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4366 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4367 * doc/autoconf.texi (Limitations of Builtins): Document this
4368 limitation.
4370 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4372 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4373 common code; used in many places in the tree.

4375 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
4377 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
4379 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
4380 messages when ac_unique_file is not found.
4381 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4382 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4383 commands, for consistency with AC_MSG_ERROR and such.
4385 * bin/autoconf.as: Make more use of "shift 2" in option processing.

4395 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4397 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4398 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4399 (ac_top_builddir): ... this ...
4400 (ac_top_build_prefix): ... to this; the old name is also kept, for
4401 backward compatibility.
4402 (ac_top_builddir_sub): New variable, without the trailing slash,
4403 always nonempty.
4404 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4405 * doc/autoconf.texi (Configuration Actions): Rename
4406 ac_top_builddir to ac_top_build_prefix.
4407 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
4408 at_top_builddir to at_top_build_prefix.

4416 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4418 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4419 argument to m4_foreach. I guess it was necessary in the past,
4420 but I think it's a no-op now.
4422 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4424 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4425 ``cat <<_ACEOF'' commands to one.
4426 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4427 * lib/autoconf/status.m4: On various places, use expr instead of
4428 ``echo|sed.''
4429 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4430 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4431 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4432 a range.
4433 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
4434 the wrong patterns between ``case'' and ``esac.'' The previous
4435 code had false positives.
4437 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4439 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
4440 as on 2005-05-02.
4441 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
4442 Mention LIBOBJDIR.

4504 quoting rules. Problems noted by Stepan Kasal.
4505 Also, throughout this document, be more careful about white space.
4506 "blank", "white space", and "space" all have different meanings
4507 and we should be careful to say what we mean.

4524 2005-05-02 Gary V. Vaughan <gary@gnu.org>
4526 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
4527 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
4528 set by latest automake.
4530 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
4532 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
4533 outputs 0 on GNU/Linux these days.
4535 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
4537 * doc/autoconf.texi (Autoconf Language): Add more description
4538 about quoting heuristics.
4539 (Limitations of Builtins): Describe "set -" problems.
4541 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4543 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
4544 not newline.
4546 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
4547 by AC_DEFINE; it was a mistake.
4548 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
4550 2005-04-25 Stepan Kasal <kasal@ucw.cz>
4552 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
4554 2005-04-22 Stepan Kasal <kasal@ucw.cz>
4556 * doc/autoconf.texi (External Software): Quadrigraphs are not
4557 processed correctly in AS_HELP_STRING; avoid this in the examples.
4558 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4559 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
4560 comment and reduce m4_default([foo], []) to [foo].
4561 (m4_strip): Update the explanation.
4563 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4565 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
4566 Remove core.conftest.* too; it's generated by Tru64 5.1.
4567 Problem reported by Jennis Pruett.
4568 * lib/autoconf/functions.m4
4569 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4570 Don't bother to remove core files; AC_RUN_IFELSE should do that
4571 for you.
4573 2005-04-19 Stepan Kasal <kasal@ucw.cz>
4575 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

4615 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4617 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
4618 Merge `-z option' as well for the benefit of Solaris link flags. Pass
4619 whole-archive (-zallextract, -zdefaultextract) options in the hope of
4620 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
4621 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
4623 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
4625 * NEWS: The configure command now warns you if you attempt to use
4626 a directory whose name contains a special character like space,
4627 newline, or "\".
4628 * doc/autoconf.texi (Installation Directory Variables): Allow
4629 "," in file names. Do not use \@; it's not a portable regexp.
4630 * bin/Makefile.am (edit): Likewise.
4631 * lib/Makefile.am (edit): Likewise.
4632 * tests/Makefile.am (edit): Likewise.
4633 * tests/semantics.at: Likewise.
4634 * tests/torture.at: Likewise.
4635 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
4636 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
4637 * doc/autoconf.texi (File System Conventions): Warn about
4638 unportable file names.
4639 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4640 (AC_INIT): Use it.
4641 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4642 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4643 ac_pwd, and quote srcdir.
4644 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4646 * doc/autoconf.texi: Fix some systematic formatting problems.
4647 ".)" needs a following @: if not at the end of a sentence, and
4648 similarly for "!)". "etc." should be preceded by a comma.
4649 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4651 2005-03-22 Bruno Haible <bruno@clisp.org>
4653 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4654 argument is often called 'build-aux'.
4656 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4658 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4659 macro AC_TRY_LINK is obsolete.
4660 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4661 `AC_CONFIG_FILES'.
4663 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4665 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4666 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4667 from a Common Lisp's `cl'.
4668 (AC_PROG_CXX): Behave according to the documentation: don't
4669 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4670 make the variable CCC precious; use `cl.exe', not `cl'.
4672 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4673 Alexandre Duret-Lutz <adl@gnu.org>
4675 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4676 /dev/null, as "configure" shouldn't read stdin, and this insulates
4677 us from problems (e.g., when testing for "cl"). Also, do this
4678 redirection before invoking "hostname" or "uname", and keep the
4679 original input stream available via...
4680 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4681 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4682 bother with "</dev/null" since it's now done at the top of
4683 'configure'.
4684 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4685 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4686 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.

4689 * tests/base.at (Input/Output): New test.
4691 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4693 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4694 newline if neither \c nor -n work, as that would output two
4695 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4697 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4699 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4700 This causes that any required macros inside will get before the if.
4701 * doc/autoconf.texi (autom4te.cache): A typo.
4703 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
4705 Undo previous change, except keep the change to
4706 lib/autoconf/programs.m4 that replaced grep with shell
4707 pattern-matching. This is because net-snmp configure reads stdin.
4708 Reported by Noah Misch.
4710 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
4712 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
4713 from /dev/null, as "configure" shouldn't read stdin, and this
4714 insulates us from problems (e.g., when testing for "cl").
4715 Suggested by Alexandre Duret-Lutz. Also, do this redirection
4716 before invoking "hostname" or "uname".
4717 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4718 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
4719 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
4720 "</dev/null" since it's now done at the top of 'configure'.
4721 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4722 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4723 Also, replace grep with shell pattern-matching, to save a process.
4725 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
4727 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4728 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
4729 avoid thinking that Allegro Common Lisp's "cl" command is a C++
4730 compiler.
4732 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
4734 * doc/autoconf.texi (Limitations of Usual Tools): Document that
4735 grep -q isn't portable. Improve grep -s explanation.
4736 Problem reported by Dan Manthey.
4738 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
4740 * doc/autoconf.texi (Special Shell Variables): Clarify
4741 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
4743 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4745 * doc/autoconf.texi: Use @acronym for DJGPP.
4746 Fix some @code's that should have been @env's, and vice versa.
4747 Sort environment variable names.
4748 Mention that shells no longer inherit IFS.
4749 Don't recommend PATH_SEPARATOR=';' so strongly.
4750 Mention that $RANDOM might expand to the empty string.
4751 "symlink" and "soft link" -> "symbolic link".
4752 Improve mktemp description (reported by Bruno Haible).
4754 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
4756 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
4757 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
4758 Likewise.
4759 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
4760 Likewise.
4762 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
4764 * NEWS: Mention AT_COPYRIGHT.
4766 * tests/local.at (AT_CMP): Use diff directly on input files rather
4767 than copying them.
4769 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
4770 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
4772 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4773 and Paul Eggert <eggert@cs.ucla.edu>
4775 * tests/autotest.at (Empty test suite): New test.
4776 * tests/torture.at (Substitute and define special characters)
4777 (Substitute a 2000-byte string, Define to a 2000-byte string)
4778 (Substitute a newline, Define a newline): New tests.
4780 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4782 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
4783 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
4784 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
4785 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
4786 (Standard regular expressions): New test.
4787 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
4788 excess test name quoting.
4789 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
4790 CPPFLAGS to `configure' instead of setting it in `configure'.
4792 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
4793 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
4794 on some platforms.
4796 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
4797 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
4799 * tests/local.at (AT_CMP): New macro.
4800 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
4801 (AC_SAVE_STATE): Move environment grep...
4802 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
4803 (AT_CONFIG_CMP): New macro.
4804 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
4805 * tests/c.at (Extensions): Do not exit early.
4806 * tests/atlocal.in: Inherit $GREP.
4808 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
4809 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
4811 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
4812 (AC_COPYRIGHT): Factor header comment portion out and move into...
4813 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
4814 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
4815 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
4816 --version output.
4817 * tests/local.at: Add Autoconf test suite copyright notice.

4820 2005-02-04 Bruno Haible <bruno@clisp.org>
4821 and Paul Eggert <eggert@cs.ucla.edu>
4823 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
4825 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
4827 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
4828 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
4830 Try not to generated lines of unlimited length, as POSIX places a
4831 2047-byte limit on line length of portable text files.
4832 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
4833 Use newline as a separator, not space.
4834 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
4835 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
4836 space.
4838 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4840 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
4841 as_func_*. Add test to check whether positional parameters
4842 are restored after function return.
4844 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
4846 * doc/autoconf.texi (Special Shell Variables): Mention _,
4847 BIN_SH, DUALCASE. Say that variables other than "status" are safe
4848 if they contain a lower-case letter. The DUALCASE problem was
4849 reported by Ralf Wildenhues.
4851 * bin/autoconf.as: Don't exit with status 0 after write failure
4852 with --help or --version.
4853 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
4854 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
4856 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4858 * doc/autoconf.texi (Limitations of Usual Tools):
4859 Unicos 9 sed limitations.
4860 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
4861 to get the option-enhanced interface on older Crays. Try ftn for
4862 Fortran 95 (newer Crays).
4864 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
4866 * man/Makefile.am (.x.1): Go back to the simple solution, but take
4867 care to echo the commands, so the user knows what's going on.
4868 Modified from a suggestion by Stepan Kasal.
4870 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
4871 with a cross reference. Derived from a suggestion by Bruce Korb.
4873 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
4875 * doc/autoconf.texi (config.status Invocation): Warn about
4876 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
4877 * doc/install.texi (Defining Variables): Likewise.
4878 Based on a proposed patch by Ralf Wildenhues.
4880 * man/Makefile.am (.x.1): Make sure the required generated files
4881 are up to date. Problem and original solution proposed by Stepan Kasal.
4882 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
4883 implicit-man-prerequisites): New rules, used by the above.
4885 * doc/make-stds.texi, doc/standards.texi: Sync from gnulib.
4886 * config/config.guess, config/config.sub, config/install-sh: Likewise.
4887 * config/missing, config/texinfo.tex: Likewise.
4889 2005-01-29 Stepan Kasal <kasal@ucw.cz>
4891 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
4892 Update the long comment explaining it.
4894 m4_require no longer writes an ``is required by'' line to the
4895 execution stack. It contains only one bit of non-redundant
4896 information: that the macro was required, not called. And even
4897 this bit is useless in most situations: have you ever met a macro
4898 which both calls and requires the same macro?
4900 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
4901 (_m4_defun_pro_outer): ... only via this macro, for the outermost
4902 macro.
4903 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
4904 (m4_expansion_stack_pop): Remove the misplaced comment.
4905 (m4_require): Don't put the ``is required by'' line to the
4906 execution stack; slightly improve the out-of-a-defun error message.
4907 (_m4_divert_grow): New macro, counter for the temporary diversions.
4908 (_m4_require_call): Use it.
4909 * tests/m4sugar.at (m4_require): Expect output without the
4910 ``is required by'' messages.
4912 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4914 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
4915 rather than x for expr.
4917 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
4918 this is safe.
4919 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
4920 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
4921 * lib/autotest/general.m4 (AT_INIT): Likewise.
4922 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Likewise.
4923 * tests/mktests.sh: Likewise.
4925 2005-01-27 Akim Demaille <akim@epita.fr>
4927 Have autoheader honor --force.
4929 * doc/make-stds.texi, doc/standards.texi: Update from masters.
4930 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
4931 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
4932 from masters, so that FileUtils.pm's update_file provide --force
4933 support.
4934 * bin/autoheader.in: Pass $force to update_file so that
4935 config.h.in is always recreated when --force.
4937 2005-01-24 Stepan Kasal <kasal@ucw.cz>
4939 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
4941 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
4943 * doc/autoconf.texi (Limitations of Builtins): Clarify that
4944 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
4946 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
4948 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
4949 Warn about newline stripping in `` and $(). Update Solaris
4950 version to 9.
4951 (Limitations of Builtins): Use expr "X...", not expr "x...", as
4952 X insulates us from future changes to Posix.
4953 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
4954 stripping.
4956 2005-01-19 Stepan Kasal <kasal@ucw.cz>
4958 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

5320 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5321 "char c = '\200';" rather than "char c = 0x80;" as the

5425 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
5426 Problem reported by Stepan Kasal.
5428 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
5430 Fix problems reported by Andreas Buening in:
5431 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
5432 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
5433 in test makefile.
5434 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
5435 readable; it's not true in OS/2-emx.
5437 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
5439 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
5440 "/usr/include", clear ac_x_includes instead of leaving it as "no"
5441 (trivial change). Problem and patch reported by Andrew Church in:
5442 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
5444 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
5446 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
5447 three args in examples. Problem reported by Frederik Fouvry in:
5448 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
5449 Also, fix some minor spacing and punctuation bugs.
5451 2004-09-02 Akim Demaille <akim@epita.fr>
5453 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
5454 "case" to restore ordering.
5455 Reported by Stepan Kasal.
5457 2004-08-26 Akim Demaille <akim@epita.fr>

5471 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
5472 texinfo.tex for now (done by hand now).
5473 * Makefile.maint (wget_files, cvs_files):
5474 Remove ansi2knr.c; nobody uses it.
5475 (ansi2knr.c-url_prefix): Remove.
5476 (cvs-update): Fix test for failure. I don't know why it ever
5477 worked...
5479 * doc/autoconf.texi: Update URLs, some of which went stale.
5480 Use @uref rather than @href.
5482 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
5483 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
5485 * config/config.guess, config/config.sub, config/elisp-comp,
5486 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
5487 doc/fdl.texi, doc/standards.texi: Sync with master copy.
5489 * NEWS, TODO, configure.ac, bin/autoscan.in,
5490 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
5491 doc/install.texi, lib/Autom4te/Configure_ac.pm,

5495 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
5496 tests/tools.at, tests/torture.at:
5497 Use "file name" rather than "filename" or "path",
5498 to be consistent with the terminology of the GNU coding standards.
5500 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
5502 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
5503 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
5504 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
5505 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
5507 More fixes to support spaces in the name of the build directory.
5508 This isn't a complete fix but it's an improvement.
5510 * bin/autoconf.as (autom4te_options): New var.
5511 Use it instead of appending to AUTOM4TE, so that we can allow
5512 spaces in the build directory's absolute name.
5513 * bin/autoheader.in ($autoconf): Allow spaces in file names.
5514 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
5515 AT_CHECK_NOESCAPE): Likewise.
5516 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
5517 main program): Likewise.
5519 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
5521 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
5522 From Ralf Corsepius in:
5523 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
5525 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
5527 * doc/autoconf.texi (Function Portability): Document isinf and
5528 and isnan. From a suggestion by Kevin Ryde.
5530 * lib/Autom4te/General.pm (END): Return correct exit status even
5531 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5533 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5535 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5536 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5537 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5539 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5541 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5542 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5543 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5544 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5545 * lib/autom4te.in (Automake-preselections): Preselect
5546 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5548 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5550 * lib/autom4te.in (Automake-preselections): Preselect
5551 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5552 trace them.
5554 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
5556 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
5557 Tru64.
5558 * doc/autoconf.texi (Shellology): Mention BIN_SH.
5559 Document problem with "`""`" in pdksh POSIX mode.
5561 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5563 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5564 with pdksh, too. Problem reported by Patrick Welche via
5565 Gary V. Vaughan.
5566 * doc/autoconf.texi (Shellology): Note that set -o posix is
5567 useful for pkdsh, too.
5569 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5571 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5572 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5573 Don't fail if ENV or BASH_ENV is readonly.
5574 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5575 etc. are read only. Problem reported by Ludovic Courtes.
5577 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5579 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5580 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5581 (trivial change)
5583 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5585 * doc/autoconf.texi (File System Conventions): Warn about
5586 names like "aux". Problem reported by Eric Blake.
5588 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5589 by zero instead of array size, so that we can use any arithmetic
5590 constant expression (instead of requiring an integer constant
5591 expression). This allows us to test expressions like DBL_MAX <
5592 LDBL_MAX, which didn't conform to the C standard using the old
5593 method.
5594 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5595 now that we can do floating-point tests at compile time.
5597 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5599 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5600 and LDBL_EPSILON, as the resulting expression isn't an
5601 integer constant expression and violates the C standard.
5602 Problem reported by Nelson H. F. Beebe. Also, check
5603 for "L" suffix, and check that long double doesn't have
5604 worse range or precision than double, that mixed-mode
5605 arithmetic doesn't generate a diagnostic, that double
5606 constants fit in long double.
5608 2004-06-03 Kevin Ryde <user42@zip.com.au>
5610 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5611 malloc(0) and realloc(NULL,size).
5613 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5614 Bob Proulx.
5616 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5618 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5619 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5620 by Jim Meyering.
5622 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5624 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5625 can be rewritten using if-then-else. Suggested by Bruno Haible.
5627 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5629 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5630 Problem reported by Stepan Kasal.
5632 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5634 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5635 change). Patch reported by Ralf Wildenhues in
5636 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5638 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5639 function F exists if the compiler and linker let you compile an
5640 expression like (F != 0). Recent versions of GCC optimize away
5641 the reference to F in that case, since every function address must
5642 be nonzero, so the link succeeds even if F does not exist.
5643 Problem reported by Manu in
5644 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5646 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5647 "Unix". Many uses changed.
5648 (Limitations of Builtins): Explain better why the ! command isn't
5649 portable.
5651 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
5653 * lib/autom4te.in (Automake-preselections): Preselect
5654 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5656 2004-05-19 Kevin Ryde <user42@zip.com.au>
5658 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5659 referencing AC_FUNC_STRERROR_R.
5661 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5662 note pessimistic assumption when cross compiling.
5664 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5666 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5667 (until 2004) invoked subcommands with sh -e, contra POSIX.
5668 Reported by Kevin Ryde.
5670 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5672 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5673 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5674 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5675 `test -f " /usr/bin/grep"', which _always_ failed.
5676 (AC_PROG_SED): Ditto bogus PATH fix.
5677 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5678 requires that grep correctly supports _multiple_ `-e' options, rather
5679 than stating only that grep should accept `-e'.
5681 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5683 Port to C99, which requires that 'exit' be declared.
5685 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5686 to ensure that stdlib.h is included.
5687 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5688 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5689 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5690 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5691 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5692 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5693 when using 'exit' in a test; C99 requires that 'exit' be declared.
5695 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5697 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5698 now prefers 'grep' implementations that accept -e.
5699 (Limitations of Usual Tools): Describe problems of traditional
5700 egrep and fgrep with long input lines, and of traditional grep
5701 with -e.
5702 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
5703 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
5704 All callers changed. Append /usr/xpg4/bin to the PATH, for
5705 Solaris.
5706 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
5707 the user with complaints about multiple -e options.
5708 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
5709 Define it with AC_PROG_GREP.
5710 * configure.ac (AC_PROG_GREP): Add.
5711 * lib/freeze.mk (GREP): New macro.
5713 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
5715 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
5716 a possible candidate only after all others fail, rather than
5717 consulting it first. This improves backward compatibility by
5718 better reflecting the way shell selection occurred in previous
5719 versions of Autoconf, and should help to avoid triggering latent
5720 problems in other packages, such as the one in Automake where zsh
5721 is not handled robustly:
5722 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
5723 Although it is not Autoconf's responsibility to work around
5724 problems in Automake, it nevertheless makes sense to avoid
5725 introducing unnecessary incompatibilites.
5727 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
5728 Gary V. Vaughan <gary@gnu.org>
5730 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
5731 how deeply nested we are when a suitable tool is found, set the
5732 ac_path_TOOL_found flag.
5733 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
5734 nested we are in this macro. Break out of all 3 nested loops if
5735 ac_path_TOOL_found is set.
5737 2004-04-21 Gary V. Vaughan <gary@gnu.org>
5739 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
5740 of the _AS_PATH_WALK loop too if GNU flavor is found.
5742 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
5744 * doc/autoconf.texi (Limitations of Make): Update documentation
5745 for `$<'. New entry `Long lines', based on a report from Simon
5746 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
5747 paragraph about DJGPP, based on a mail from Richard Dawe.
5749 2004-04-20 Paul Eggert <eggert@twinsun.com>
5751 * tests/c.at (C keywords): Don't assume that GCC supports
5752 "restrict" and "inline", as sufficiently-old GCC versions do not
5753 (also, GCC configured to be in pedantic C89 mode does not).
5754 Problem reported by Sumit Pandya in:
5755 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
5757 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
5758 consider -g to work if it generates warnings when plain compiles
5759 don't. Problem reported by Braden McDaniel in:
5760 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
5762 * doc/autoconf.texi (Slashes): New section, to document a problem
5763 reported by Jim Meyering in:
5764 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
5766 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
5767 linker output files before linking, to work around IRIX 6 linker bug.
5768 Problem reported by Rainer Orth in:
5769 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
5771 2004-04-20 Gary V. Vaughan <gary@gnu.org>
5773 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
5774 best tool so far counter rely on the tool path variable name to
5775 avoid checks for one tool being affected by the results of running
5776 the length check on a previous tool.
5778 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
5779 match expression argument, as different greps have different
5780 regular expression flavours.
5781 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
5782 literals.
5783 (AC_PROG_EGREP): Pass 'EGREP$'.
5784 (AC_PROG_GREP): Pass 'GREP$'.
5786 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
5788 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
5789 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
5791 2004-03-29 Paul Eggert <eggert@twinsun.com>
5793 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
5794 Types, Specific Compiler Characteristics, System Services,
5795 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
5796 etc. consistently instead of 'long', 'short', 'unsigned' etc.
5797 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
5798 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
5799 Likewise.
5800 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
5801 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
5802 AC_TYPE_OFF_T): Likewise.
5803 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
5804 Likewise.
5806 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
5807 pacify libtool 1.5.2. Fix quoting problems in sed command.
5809 2004-03-28 Paul Eggert <eggert@twinsun.com>
5811 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
5812 now defines HAVE_DECL_TZNAME if it is declared, when
5813 HAVE_STRUCT_TM_TM_ZONE is not defined.
5814 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
5815 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
5816 for HAVE_TZNAME.
5818 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
5820 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
5821 superfluous backslashing of quotes (") in sed expressions;
5822 thanks to Paul Eggert.
5824 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
5826 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
5827 Fortran compiler is ifort, also added pghpf; thanks to Nelson
5828 H. F. Beebe for the bug report.
5830 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
5832 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
5833 quoted -cmdline argument in Portland Group compiler (bug
5834 reported by Jeffrey J. Barteet).
5836 2004-03-25 Kevin Ryde <user42@zip.com.au>
5838 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
5839 (Run Time): ... here, where it's now mentioned.
5841 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
5843 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
5844 inherits from language Autoconf-without-aclocal-m4.
5845 (Customizing autom4te): Adjust example; the cache must now be
5846 disabled for language Autoconf-without-aclocal-m4.
5848 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
5849 Nathanael Nerode <neroden@twcny.rr.com>
5851 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
5852 AC_CHECK_TOOLS): Warn if a cross-tool is found without
5853 a prefix.
5854 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
5855 AC_CHECK_TARGET_TOOLS): New macros.
5856 * doc/autoconf.texi (Generic Programs): Document
5857 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
5858 AC_CHECK_TARGET_TOOLS, and warn for future changes
5859 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
5860 AC_CHECK_TOOLS.
5861 (Specifying Names): Document the reason for these future
5862 behavioral changes.
5863 * tests/mktests.sh: Do not generate tests for the
5864 new macros.
5865 * NEWS: Document these changes.
5867 * doc/autoconf.texi: Avoid macros with unbraced arguments,
5868 they make TeX hang up.
5870 2004-03-15 Paul Eggert <eggert@bogus.example.com>
5872 * NEWS: New macro AC_CHECK_ALIGNOF.
5873 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
5874 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
5875 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
5876 vowel.
5877 (AC_CHECK_ALIGNOF): New macro.
5878 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
5879 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
5880 those for sizeof.
5882 2004-03-03 Paul Eggert <eggert@twinsun.com>
5884 * bin/Makefile.am (edit): Don't use $< in a context where
5885 POSIX doesn't require support for it. Use $@.in instead.
5886 Problem reported by Anthony N. Frasso in
5887 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
5888 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
5890 2004-02-23 Gary V. Vaughan <gary@gnu.org>
5892 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
5893 from the next generation of Libtool.
5894 * lib/autom4te.in (Autoreconf-preselections): Ditto.
5896 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5898 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
5899 is not always thread-safe. Report from Nathanael Nerode.
5901 2004-02-18 Paul Eggert <eggert@twinsun.com>
5903 Fix a dependencies problem, stemming from a Autoconf 2.59 build
5904 problem on QNX reported by Stephen Rasku in
5905 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
5907 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
5908 $(m4sh_m4f_dependencies); this removes a FIXME.
5909 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
5910 (MAINTAINERCLEANFILES): Split into pieces,
5911 one per related section. Add $(srcdir)/wrapper.in.
5913 2004-02-09 Paul Eggert <eggert@twinsun.com>
5915 * doc/autoconf.texi (Setting Output Variables): Emphasize that
5916 AC_SUBST provides no portable way to escape literal newlines.
5918 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
5919 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
5920 Darwin uses -lcrt2.o and there's little point to cataloging all
5921 the system variants. Partial fix reported by Andreas Waechter in:
5922 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
5923 for bug reported by Nelson H. F. Beebe in:

5926 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
5928 * doc/autoconf.texi (AU_DEFUN): Fix English,
5929 suggested by Paul Eggert.
5930 * lib/autoconf/autoupdate.m4: Correct reference to
5931 acobsolete.m4, suggested by Alexandre Duret-Lutz.
5933 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
5935 * bin/autoupdate.in: Define __file__ so that warnings
5936 refer to the correct file.
5937 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
5938 the behavior of the third argument.
5939 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
5940 correctly the behavior of the third argument. Document
5941 what the three macros that AU_DEFUN defines do. Fix
5942 warning message when the third argument includes $0
5943 (reported by Alexandre Duret-Lutz).
5945 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5946 Eric Sunshine <sunshine@sunshineco.com>
5947 Paul Eggert <eggert@twinsun.com>
5949 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
5950 (AS_INIT): Output shell initialization there. Removed optional
5951 parameter. Expand _AS_SHELL_FN_SPY.
5952 (AS_INIT_WITH_SHELL_FN): Removed.
5953 (_AS_SHELL_FN_SPY): New macro.
5954 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
5955 macros.
5956 (AS_SHELL_SANITIZE): Remove loop to find better shell
5957 and documentation for the parameter.
5958 (_AS_DETECT_BETTER_SHELL): Move it here.
5959 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
5960 (_AS_RUN): Move it here, support testing with eval.
5961 (AS_REQUIRE_SHELL_FN): Require shell functions when
5962 it is used.
5963 (_AS_LINENO_WORKS): Put around braces, we do not
5964 trigger the bash bug anymore.
5965 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
5966 use AS_INIT_WITH_SHELL_FN.
5967 * bin/autoconf.in, tests/wrapper.in: Regenerated.
5969 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5971 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
5972 * doc/autoconf.texi: Don't say that the third parameter
5973 is broken.
5974 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
5975 (AU_DEFUN): Honor the third parameter, create autoupdate
5976 macros with AU_DEFINE.
5977 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
5978 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
5979 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
5980 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
5981 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,
5982 AC_ARG_ARRAY, AC_CYGWIN, AC_EMXOS2, AC_MINGW32,
5983 AC_XENIX_DIR): Likewise.
5984 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS,
5985 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
5986 * lib/autoconf/status.m4: Remove FIXME.
5987 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
5988 that the macro is not present anymore in the updated
5989 configure.ac.
5990 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
5991 of autoupdate.
5993 2004-01-28 Paul Eggert <eggert@twinsun.com>
5995 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
5996 copyright years.
5997 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
5998 2003 (except 1997) to the list of copyright years. This undoes
5999 the 2003-05-22 change, which removed the older years from the list.
6000 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
6002 2004-01-27 Gary V. Vaughan <gary@gnu.org>
6003 Albert Chin-A-Young <china@thewrittenword.com>
6005 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
6006 grep or ggrep program in PATH that accepts as long lines as
6007 possible.
6008 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
6009 AC_PROG_GREP.
6010 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
6011 egrep and fgrep respectively if $GREP -E/-F don't work.
6012 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
6013 _AC_PROG_GREP, and AC_PROG_SED.
6014 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
6015 longest input length accepted by a command.
6016 (AC_PROG_SED): Use it.
6017 * doc/autoconf.texi (Particular Programs): Document the changes.
6018 * NEWS: Updated.
6020 2004-01-27 Paul Eggert <eggert@twinsun.com>
6022 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
6023 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
6024 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
6025 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
6027 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
6028 bin/autoconf.in, config/Makefile.in, config/config.guess,
6029 config/config.sub, config/install-sh, config/mdate-sh,

6040 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
6041 tests/actypes.at: Regenerate and/or sync with original
6042 sources.
6044 2004-01-26 Paul Eggert <eggert@twinsun.com>
6046 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6047 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6048 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6049 not <inttypes.h>. Problem reported by Tim Mooney in
6050 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6051 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6052 Likewise.
6054 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6055 otherwise "make check" fails because it forbids cmp (I guess
6056 because cmp treats files as binary on DOS-like systems).
6058 * tests/mktests.sh: Update copyright date to 2004, since some tests
6059 have changed in 2004.
6061 2004-01-23 Gary V. Vaughan <gary@gnu.org>
6063 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
6064 non-truncating sed or gsed program in PATH.
6065 * tests/acprograms.at: Add it.
6066 * doc/autoconf.texi (Particular Programs): Document it.
6067 * NEWS: Updated.
6069 2004-01-15 Paul Eggert <eggert@twinsun.com>
6071 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6072 -std1 disables some useful extensions on Tru64. Problem reported
6073 by N. Lichtmaier in
6074 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6076 2004-01-14 Paul Eggert <eggert@twinsun.com>
6078 * doc/autoconf.texi (Programming in M4sh): Document that
6079 AS_MKDIR_P succeeds if the destination is a symbolic link
6080 to an existing directory.
6081 (Limitations of Usual Tools): Note that mkdir -p might not
6082 succeed on symlinks to directories.
6084 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6086 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6087 * bin/autoheader.in: Grammar fix in message.
6088 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
6089 Test for dir before calling mkdir -p. (trivial changes)
6091 2004-01-13 Eric Blake <ebb9@byu.net>
6093 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
6094 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6096 2004-01-10 Jim Meyering <jim@meyering.net>
6098 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6100 2004-01-09 Paul Eggert <eggert@twinsun.com>
6102 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6103 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6104 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6105 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6106 AC_COMPILE_IFELSE, since we now assume our caller invokes
6107 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6108 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6109 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6110 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6112 2004-01-07 Paul Eggert <eggert@twinsun.com>
6114 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6115 `"'...'"`, as it's confusing (and I suspect it may not work on
6116 some platforms). The code was incorrect anyway, as it assumed
6117 that \$ evaluated to itself in that context. Reported by
6118 Alexandre Duret-Lutz.
6120 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6122 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
6123 and _LT_AC_TAGCONFIG.
6125 2004-01-06 Paul Eggert <eggert@twinsun.com>
6127 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6128 example, and add more examples. Reported by Eric Sunshine.
6130 2004-01-05 Paul Eggert <eggert@twinsun.com>
6132 * doc/autoconf.texi (Limitations of Usual Tools):
6133 Remove warning against "rm -fr" introduced yesterday; it
6134 was a false alarm.
6136 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6137 autoscan, autoupdate, ifnames): Don't use chmod -w.
6138 * lib/Makefile.am (autom4te.cfg): Likewise.
6139 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6140 "chmod -w".
6142 2004-01-04 Paul Eggert <eggert@twinsun.com>
6143 Paolo Bonzini <bonzini@gnu.org>
6145 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
6146 by doing lineno substitution only on lines containing "$LINENO".
6148 2004-01-04 Paul Eggert <eggert@twinsun.com>
6150 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6151 Use "rm -f" to remove conftest.sed, not plain "rm".
6152 Bug reported by David Relson in
6153 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6155 * Makefile.am (autom4te-update):
6156 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6157 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6158 * doc/autoconf.texi (Guidelines): Likewise.
6159 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

6164 * tests/Makefile.am (clean-local): Likewise.
6165 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
6166 srcdir): Likewise.
6167 * doc/autoconf.texi (Limitations of Usual Tools):
6168 Warn against "rm -fr".
6170 2004-01-03 Paul Eggert <eggert@twinsun.com>
6172 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6173 -c -o might not work. From a suggestion by Kevin Ryde.
6174 (C Compiler, Generating Sources, Limitations
6175 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6176 Don't put '-o' after non-options, as POSIX doesn't allow this.
6177 Mention that cc's name might be gcc or c89 or whatever.
6179 2004-01-04 Kevin Ryde <user42@zip.com.au>
6181 * doc/autoconf.texi: Add various further index entries.
6183 2003-12-29 Paul Eggert <eggert@twinsun.com>
6185 * bin/autoreconf.in (autoreconf_current_directory):
6186 Fix typo: mkdir without umask arg.
6188 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6190 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6191 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6192 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6193 explanation clearer.
6195 2003-12-24 Andreas Schwab <schwab@suse.de>
6197 * doc/autoconf.texi (Default Includes): Fix misspelling of
6198 AC_INCLUDES_DEFAULT.
6200 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
6202 * configure.ac: Test if sh -n works.
6203 * configure: Regenerate.
6204 * tests/atlocal.in: Store the result here.
6205 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
6206 tools.at, looking in atlocal's ac_cv_sh_n_works instead
6207 of explicitly testing.
6208 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
6209 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
6210 * tests/tools.at (Syntax of the shell scripts): Simplify
6211 using AT_CHECK_SHELL_SYNTAX.
6212 (Syntax of the Perl scripts): Remove definition of
6213 AT_CHECK_PERL_SYNTAX.
6215 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
6217 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
6218 stderr to /dev/null.
6219 * bin/autoconf.in: Regenerate.
6220 * bin/wrapper.in: Regenerate.
6222 2003-11-26 Paolo Bonzini <bonzini@gnu.org>
6224 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
6225 Extracted from AS_SHELL_SANITIZE.
6226 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
6227 macros.
6228 (AS_SHELL_SANITIZE): Move reinvocation code from
6229 _AS_LINENO_WORKS, use it to find out if shell
6230 functions work.
6231 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
6232 does not work.
6233 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
6234 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

6245 (&sizes): New.
6246 Use them.

6248 them on the fly.
6250 2003-11-24 Akim Demaille <akim@epita.fr>
6252 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

6280 parameter of AU_DEFUN.
6281 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.

6285 the expanded body, consistently with other macros such as AC_USG.
6287 2003-11-17 Paul Eggert <eggert@twinsun.com>
6289 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
6290 into the initial confdefs.h, to work around a bug in NextStep 3.3
6291 patch 3 reported by Eric Sunshine.
6293 2003-11-15 Kevin Ryde <user42@zip.com.au>
6295 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
6296 than $target since the latter is not usual, add guidelines on when to
6297 use or not use the system type.
6299 2003-11-12 Derek Price <derek@ximbiot.com>
6301 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
6302 typo misrepaired by an auto-spellcheck.
6304 2003-11-12 Akim Demaille <akim@epita.fr>

6307 --force-missing unless it actually supports it.
6308 From Debian #219336.
6310 2003-11-12 Akim Demaille <akim@epita.fr>

6454 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
6456 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
6457 cross test.
6459 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
6461 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
6462 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

6473 Issue a more-informative diagnostic.
6474 Problems reported by Eric Sunshine.
6476 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
6478 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
6479 -mGLOB_options_string stuff for Intel ifc, which can cause

6489 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
6490 that future autopoint/aclocal/automake/autoreconf will be able

6499 -lcrt[01].o.
6501 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
6503 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6504 cache variable instead of $G77 to decide whether to include -O2,
6505 since $G77 is specific to Fortran 77.
6507 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6509 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
6510 free" flag. Re-order flags tested into rough order of popularity.
6512 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6514 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
6515 arguments so that it can be used with syntax identical to
6516 AC_PROG_F77, and so that we can more easily decide to
6517 remove/deprecate the DIALECT optional argument in the future if it
6518 proves troublesome.
6519 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
6520 non-freeform-supporting compilers. Document freeform flags.
6522 2003-10-03 Akim Demaille <akim@epita.fr>
6524 * configure.ac: Look for emacs, not macs.

6527 2003-10-03 Akim Demaille <akim@epita.fr>
6529 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
6530 * bin/autoreconf.in (autoreconf_current_directory): Create the

6532 Suggested by Alexandre Duret-Lutz.
6534 2003-10-03 Akim Demaille <akim@epita.fr>
6536 * configure.ac: Quotation and formatting changes.

6558 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
6559 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
6561 2003-09-30 Akim Demaille <akim@epita.fr>
6563 * config/announce-gen (&print_news_deltas): Extracted from...
6564 (&print_changelog_deltas): here.
6565 (&news_file): Rename as...
6566 (@news_file): this.

6583 Problem reported by Lars J. Aas in
6584 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
6585 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
6586 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
6587 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
6589 2003-09-26 Akim Demaille <akim@epita.fr>
6591 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6592 directory for AC_CONFIG_COMMANDS' first argument exists.
6593 This makes valid the invocation of _AC_SRCPATH that follows.
6594 Reported by Eric Sunshine.
6595 * doc/autoconf.texi (Configuration Commands): Adjust.
6597 2003-09-26 Akim Demaille <akim@epita.fr>
6599 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6600 Reported by Ralf Corsepius.
6602 2003-09-26 Akim Demaille <akim@epita.fr>
6604 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6605 arguments.
6606 Actually, use AU_ALIAS.
6607 From Bruno Haible.

6616 2003-09-26 Akim Demaille <akim@epita.fr>
6618 The test suite are sometimes assigning timings incorrectly.
6619 Reported by Henk Krus.
6620 Diagnosed by Nicolas Joly.
6622 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6623 AT_help_all.
6624 Instead of making AT_help a sequence of assignments to grow
6625 $at_help_all, just make AT_help_all be the growing contents of
6626 $at_help_all, and make a single assignment in...
6627 (AT_INIT): here.
6628 (at_times_skip): Flip the meaning and rename as...
6629 (at_times_p): this.
6630 (AT_INIT): When summarizing the test that ran, remove
6631 $at_times_file after use, and check it is present before trying to
6632 use it.
6634 2003-09-25 Akim Demaille <akim@epita.fr>
6636 Version 2.57d.
6638 * bin/Makefile.am (edit): Handle '@configure_input@'.
6639 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
6640 (ifnames): chmod -w.
6641 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6642 executables, not bin/ executables! Otherwise all the magic needed
6643 to find non installed files is turned off. This caused a failure
6644 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6645 as found in its environment (sent by tests/autoreconf): pointing
6646 to bin/autom4te that could not find its files.
6647 * tests/mktests.sh: Force the replacement of generated files, for
6648 the sake of "mv" program that are interactive when overwriting a
6649 -w file.
6650 * config/install-sh: Upgrade from CVS Automake.
6652 2003-09-23 Paul Eggert <eggert@twinsun.com>
6654 * doc/autoconf.texi (Limitations of Builtins): Document test -h
6655 versus test -L issues.
6657 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
6658 Paul Eggert <eggert@twinsun.com>
6660 Trivial change to support GCC's configuration procedure.
6661 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
6662 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
6663 about inconsistency if the preprocessor is set to give errors for
6664 any warning.
6665 * doc/autoconf.texi (C Compiler Characteristics): Document this.
6667 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
6669 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
6670 and XFile.pm from Automake.

6683 2003-09-12 Akim Demaille <akim@epita.fr>
6685 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
6686 not asm/types.h.
6688 2003-09-11 Akim Demaille <akim@epita.fr>
6690 * doc/autoconf.texi (Header Portability): linux/random.h.
6691 From Peter Hendrickson.
6693 2003-09-10 Akim Demaille <akim@epita.fr>
6695 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
6696 willing to edit the output files.
6698 2003-09-10 Akim Demaille <akim@epita.fr>
6700 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
6701 and AC_FC_FREEFORM.
6702 * tests/mktests.sh: Skip AC_FC_SRCEXT.
6703 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
6705 2003-09-09 Akim Demaille <akim@epita.fr>

6718 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
6719 Improve the accuracy of the wording about obsolescence.
6720 From a suggestion by Ian Lance Taylor in
6721 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
6723 2003-09-05 Paul Eggert <eggert@twinsun.com>
6725 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
6726 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
6728 2003-09-04 Akim Demaille <akim@epita.fr>
6730 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
6731 AC_FUNC_WAIT3.
6733 2003-09-04 Akim Demaille <akim@epita.fr>
6735 * bin/autom4te.in: Use &fatal where more appropriate than &error.
6736 (freeze): When exiting, use $exit_code.

6743 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
6745 Add support for newer Fortran dialects. The F77 interface is
6746 unchanged, and continues to support Fortran 77. New FC macros
6747 correspond to all the old F77 macros, with output variables FC,
6748 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
6749 available dialect, but older dialects can be specified. There are
6750 new macros AC_FC_SRCEXT to set the source extension, and
6751 AC_FC_FREEFORM to accept free-form source files.
6753 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
6754 New macros.
6755 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

6771 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
6772 Rewrite in terms of the above.
6773 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
6774 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

6780 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
6781 Document problems with timestamp resolution that 'make', 'cp -p', and
6782 'touch -r' have.
6784 2003-08-27 Akim Demaille <akim@epita.fr>
6786 * tests/m4sugar.at (cross_warning): Make sure to enable the
6787 output, so that we can track spurious m4sugar output.
6788 * tests/local.at: Require 2.57.
6789 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
6790 are defaulted by AT_CHECK anyway.
6791 Use AT_CHECK_AUTOM4TE.
6792 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
6793 missing dnl.
6795 2003-08-27 Akim Demaille <akim@epita.fr>
6797 * bin/autoheader.in: Issue the "Using auxiliary..." message only
6798 when -Wobsolete is set.
6799 Set it on by default.
6800 Suggested by Klee Dienes.
6802 2003-08-27 Akim Demaille <akim@epita.fr>
6804 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
6805 documentation.
6806 From Guido Draheim.
6808 2003-08-26 Akim Demaille <akim@epita.fr>
6810 * doc/autoconf.texi (Output): Make clear that one can run code
6811 after AC_OUTPUT.
6813 2003-08-25 Akim Demaille <akim@epita.fr>
6815 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
6816 CVS Bison.
6818 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
6820 * bin/autoreconf.in (parse_args): Do not pass --no-force to

6830 * configure.ac: Bump to 2.57c.
6832 2003-08-22 Akim Demaille <akim@epita.fr>
6834 Version 2.57b.
6836 * Makefile.cfg (local-checks-to-skip): New.
6837 * Makefile.maint (local-check): Rename as...
6838 (local-checks-available): this.
6839 (local-check): New.
6841 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
6842 * configure.ac: Require Automake 1.7.6.
6844 2003-08-22 Akim Demaille <akim@epita.fr>
6846 Output stack traces in warnings.
6848 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
6849 Replace the former...
6850 (m4_warn): Pass the call stack to _m4_warn.
6851 * bin/autom4te.in: Adjust to output the call stack.
6852 * tests/m4sugar.at (m4@&t@_warn): Adjust.
6854 2003-08-22 Akim Demaille <akim@epita.fr>
6856 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
6857 * bin/autom4te.in: Adjust.
6859 2003-08-21 Akim Demaille <akim@epita.fr>
6861 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
6862 (&verbose): Remove.
6863 (&getopt): Adjust the note and verb channels, depending upon
6864 --verbose.
6865 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
6866 * bin/autoupdate.in: Adjust.
6867 Use &verb, not &verbose.
6869 2003-08-21 Akim Demaille <akim@epita.fr>
6871 * bin/autoheader.in (&parse_args): Use &parse_warnings and
6872 &parse_WARNINGS.
6873 ($help): Use Autom4te::ChannelDefs::usage.
6874 * bin/autoscan.in: Use Autom4te::ChannelDefs.
6875 * lib/Autom4te/General.pm: Don't export error: you don't own it.
6877 2003-08-21 Akim Demaille <akim@epita.fr>
6879 First stab at preserving warnings between calls to autom4te,
6880 including when the cache is used.
6882 There are still several issues: (i) there are too many runs of m4
6883 (one for include, one for warnings, and some more), (ii) warnings
6884 spreading on several lines are not handled gracefully, (iii) the
6885 code meant to have the call stack display for errors does not work
6886 (its handling should move from m4 to autom4te).
6888 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
6889 Use them.
6890 (@preselect): Add m4_warn.
6891 ($exit_status): Remove, use $exit_code.
6892 ($help): Use Autom4te::ChannelDefs::usage.
6893 (&handle_m4): No longer define the m4_warnings.
6894 At each run, extract and report the warnings.
6895 Always cache the result, including if the exit status is on
6896 failure, since if nothing changes, we should result in the same
6897 failure, hence we can use the cache.
6898 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
6899 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
6900 Remove.
6901 (m4_warn): Redefine as a do-nothing: it is its invocation that
6902 matters, as warnings are now reported via traces.
6903 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
6904 the contents of m4_warn: make it _call_ m4_warn, so that tracing
6905 the latter reveals calls to the former.
6907 Adjust the tests.
6909 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
6911 2003-08-21 Akim Demaille <akim@epita.fr>
6913 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
6914 Use them.
6916 2003-08-21 Akim Demaille <akim@epita.fr>
6918 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
6919 forward order.
6920 * lib/Autom4te/ChannelDefs.pm: Doc typos.
6921 (&parse_warnings): Accept a list of warning requests.
6922 (&usage): Return a string, not a side effect.
6923 (cross): New warning category.
6925 2003-08-21 Akim Demaille <akim@epita.fr>
6927 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
6928 (&require_configure_ac): Accept an optional directory argument.
6929 ($configure_ac): Remove.
6930 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
6931 (&catfile): Remove.
6932 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
6933 * bin/autoscan.in: Adjust.
6935 2003-08-20 Akim Demaille <akim@epita.fr>
6937 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
6938 Reported by Alexandre Duret-Lutz.
6940 2003-08-20 Akim Demaille <akim@epita.fr>
6942 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
6943 * bin/autom4te: Adjust.
6944 In particular, be Autoconf tools are really silent when properly
6945 working, bind the verbosity of the 'note' channel to $verbose.
6946 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
6947 (&xsystem, &contents): Remove, since they are exported by...
6948 * lib/Autom4te/FileUtils.pm: this.
6949 More perldoc.
6950 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
6951 * lib/Autom4te/FileUtils.pm: here.
6953 2003-08-20 Akim Demaille <akim@epita.fr>
6955 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
6956 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
6957 from CVS Automake.
6959 2003-08-20 Akim Demaille <akim@epita.fr>
6961 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
6962 (autom4te-update): New.
6963 * Makefile.cfg (update): Bind autom4te-update.
6965 2003-08-19 Derek Price <derek@ximbiot.com>
6967 * lib/autotest/general.m4: Comment various HELP_* diversions.
6968 (PARSE_ARGS_BEGIN): New section for option parsing related
6969 initialization.

6975 * config/announce-gen, Makefile.cfg: New.
6976 * Makefile.am: Adjust.
6977 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
6979 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
6981 * lib/autom4te.in (Automake-preselections): Preselect
6982 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
6983 and m4_sinclude.
6985 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
6987 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
6988 (Autoconf-without-aclocal-m4): ... this new language.
6989 * doc/autoconf.texi (autom4te Invocation): Mention
6990 Autoconf-without-aclocal-m4.

6994 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
6995 RUN-IF-PASS optional arguments.

7004 STDOUT & STDERR arguments.
7006 2003-08-14 Derek Price <derek@ximbiot.com>
7008 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
7009 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7010 shorter column three. Add DESCRIPTION to log file content.
7012 2003-08-13 Derek Price <derek@ximbiot.com>
7014 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
7015 output.
7017 2003-08-12 Derek Price <derek@ximbiot.com>
7019 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
7020 (AT_CHECK_NOESCAPE): Move core functionality to...
7021 (_AT_CHECK): ...this new macro.
7023 2003-08-07 Derek Price <derek@ximbiot.com>
7025 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
7026 (AT_CHECK_NOESCAPE): ...to this new macro.
7028 2003-07-31 Paul Eggert <eggert@twinsun.com>
7030 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
7031 in Bash 2.01. Problem reported by Brian Gough in
7032 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
7034 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
7036 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
7037 -lcrt1.o, for OS X. (trivial change)
7039 2003-07-07 Paul Eggert <eggert@twinsun.com>
7041 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
7042 inside '#ifndef __cplusplus'. Problem reported by
7043 Bob Friesenhahn.
7045 2003-07-06 Bill Clarke <llib@computer.org>
7047 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7048 'long', not 'int', for benefit of Sun's recent C++ compilers
7049 (trivial change). See:
7050 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
7051 (This really should be 'intptr_t', not 'long', but that would
7052 take more work.)
7054 2003-06-25 Akim Demaille <akim@epita.fr>
7056 * lib/Makefile.am (autom4te.cfg): Make it read only.
7057 Depend on Makefile since it contains substitutions.
7058 From Paolo Bonzini.
7059 * lib/autom4te.in (args): Add local.at? for Autotest args.
7060 This change was made on autom4te.cfg which is generated.
7061 Reported by Raja R. Harinath.
7063 2003-06-25 Akim Demaille <akim@epita.fr>
7065 * doc/autoconf.texi (Header Portability): sys/mount.h.
7066 From Gareth McCaughan.
7068 2003-06-23 Akim Demaille <akim@epita.fr>
7070 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7071 not all of them. This fixes 1. the fact that when testing
7072 Autoconf there are many many config.log, 2. the incorrect use of
7073 top_srcdir to find config.log.
7074 Don't mix the detailed output of failed test with the summary of
7075 failures. Rather, append detailed log afterwards.
7077 2003-06-23 Akim Demaille <akim@epita.fr>
7079 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7080 always run: output config.log on $at_group_log.
7082 2003-06-23 Akim Demaille <akim@epita.fr>
7084 * tests/torture.at (#define header templates): Don't use quotes in
7085 C++ comments as it puzzles Emacs' sh font-lock-mode.
7087 2003-06-23 Akim Demaille <akim@epita.fr>
7089 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
7090 * lib/autom4te.cfg (args): Add local.at? for Autotest args.

7094 * tests/local.at: here.
7095 * tests/Makefile.am: Adjust.
7096 * doc/autoconf.texi (testsuite Scripts): Adjust.
7098 2003-06-21 Kevin Ryde <user42@zip.com.au>
7100 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
7101 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
7102 ensuring we add -std1 for full-ANSI.
7104 * doc/autoconf.texi (hdrindex): New macro.
7105 Add index entries for portability of various standard header files.
7107 2003-06-20 Akim Demaille <akim@epita.fr>
7109 * configure.ac: Bump to 2.57b.
7111 2003-06-20 Akim Demaille <akim@epita.fr>
7113 Version 2.57a.
7115 2003-06-20 Akim Demaille <akim@epita.fr>
7117 * bin/autom4te.in: Don't rely on $HOME being defined.
7118 Reported by Marc Espie as PR/233.
7120 2003-06-20 Akim Demaille <akim@epita.fr>
7122 * lib/autotest/general.m4: Use at_times_file only if used.
7123 From Nicolas Joly.
7125 2003-06-20 Akim Demaille <akim@epita.fr>
7127 * config/config.guess, config/config.sub, config/elisp-comp,
7128 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
7129 Update from masters.
7131 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
7133 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
7134 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7135 (TEST_SCRIPT): New diversion.
7136 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7137 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7138 (AT_INIT): Support for expected failures.
7140 2003-06-02 Akim Demaille <akim@epita.fr>
7142 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7143 changes.
7144 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7145 Autoconf nor Automake.
7146 (&contents): New, from Automake.
7147 PODify.
7149 2003-05-28 Paul Eggert <eggert@twinsun.com>
7151 * NEWS, doc/autoconf.texi (Particular Functions),
7152 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7153 is the inverse of localtime.
7155 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7157 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7158 (handle_exec_errors): New function. Work around $! being
7159 altered by WEXITSTATUS.
7160 (xqx, xsystem): Use handle_exec_errors.
7162 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7164 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7165 Do not call `_exit()', simply modify `$?'.
7166 (xsystem): Reset $! before running system, and check it afterward.
7167 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7168 63 for version mismatches.
7170 2003-05-23 Akim Demaille <akim@epita.fr>
7172 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7173 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7174 the middle of a line).
7175 * lib/m4sugar/m4sugar.m4: Likewise.
7176 Remove useless spaces in comments.
7178 2003-05-23 Akim Demaille <akim@epita.fr>
7180 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7181 exit 63, so that we (or Automake's "missing") can tell the
7182 difference with a plain failure.
7183 * doc/autoconf.texi (Notices): Adjust.
7185 2003-05-23 Akim Demaille <akim@epita.fr>
7187 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7188 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7189 White spaces cleanup.
7191 2003-05-22 Jim Meyering <jim@meyering.net>
7192 Paul Eggert <eggert@twinsun.com>
7194 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7195 Remove `#include <stdlib.h>' from the list; we should never
7196 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7197 resulting namespace pollution would cause other tests to fail.
7198 Configure scripts run with some older versions of g++ and HP's
7199 aCC would fail due to such an #include. Problems reported by
7200 Matthew Mueller in <http://bugs.debian.org/120704> and by
7201 Keith Bostic in
7202 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7203 In the test, use the test declaration before including <stdlib.h>,
7204 as that's closer to how it'll be used.
7206 2003-05-23 Akim Demaille <akim@epita.fr>
7208 * doc/autoconf.texi (Header Portability): ucred.h.
7209 From Ian Redfern.
7211 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7213 Overhaul Autotest's logging: generate separate log files
7214 in testsuite.dir/NNN/testsuite.log, and append them to
7215 testsuite.log instead of re-running the test verbosely.
7217 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7218 file descriptor, write 0 to at_status_file instead of setting
7219 at_status=0, initialize some new variables (at_status_file,
7220 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7221 to rerun the tests, instead append the at_group_log to the
7222 at_suite_log when a test fails.
7223 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7224 with the AS_MESSAGE_LOG_FD redirected to stdout.
7225 (AT_CLEANUP): save the output status in $at_status_file
7226 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7227 its original place.
7228 (AT_CHECK): since tests are run with a redirected stdout,
7229 and used to be re-run in verbose mode, turn some $at_verbose
7230 into echo, and don't redirect the output of testing stdout
7231 and stderr.
7233 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7234 the name of the debugging directory and information about
7235 its contents.
7237 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7239 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
7240 parameter.

7352 and truncate.
7354 2003-05-06 Akim Demaille <akim@epita.fr>
7356 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7357 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7358 by aclocal.m4 is changed it might require the importing of another
7359 m4 extension file, i.e., aclocal must be run.
7361 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7362 (&parse_args): Use --force with aclocal if required and supported.
7363 (&autoreconf_current_directory): Use &run_aclocal.

7370 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7371 argument instead of a file name, so that the request file remains
7372 open during the whole autom4te run.
7373 ($icache_file): New.
7374 (&freeze): Lock the $icache_file.
7376 2003-04-29 Derek Price <derek@ximbiot.com>
7378 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7379 seperator with m4_append_uniq(). It doesn't work.
7380 (AT_CLEANUP): Add `;' to end of at_help_all.
7381 (AT_INIT): Allow --keywords to be specified more than once. When
7382 grepping $at_help_all for keywords, use the field and keyword
7383 seperators to ensure a complete keyword match. Alter at_prev handling
7384 to support the new --keywords behavior.
7386 2003-04-27 Karl Berry <karl@freefriends.org>
7388 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7389 align better with others. I also made some of the individual
7390 entries on one line, for brevity and to make it easier for me to
7391 sort my dir-example file in the Texinfo distribution :).
7393 2003-04-12 Jim Meyering <jim@meyering.net>

7458 header causes problems.
7460 2003-03-28 Akim Demaille <akim@epita.fr>
7462 * tests/torture.at (Configuring subdirectories): Require aclocal
7463 1.4, otherwise the test fails, as it does support configure.ac.

7468 * doc/autoconf.texi (C Compiler): `#line' portability.

7474 layout in order to allow scripting around test groups.
7476 2003-03-27 Derek Price <derek@ximbiot.com>
7478 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
7479 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
7480 use new diversions in preparation for accepting new arguments and

7488 (AC_HELP_STRING): AU_DEFUN to...
7489 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
7490 * tests/m4sh.at (AS_HELP_STRING): New test.
7492 * tests/acgeneral.at: Regenerated.
7494 2003-03-26 Derek Price <derek@ximbiot.com>
7496 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
7497 sense. Verbosify the diversion definitions comment.

7501 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to

7533 * doc/autoconf.texi (Limitations of Make): Remove the section
7534 about `$<' in inference rules, it was a bogus interpretation of
7535 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
7536 Tru64 make in the "target lookup" section.
7537 (Automake): Automake 1.5+ no longer requires special tools to be
7538 present on the developer's host.

7554 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
7555 to cope with DOS-style absolute paths, when constructing
7556 ${ac_make}.
7558 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
7559 When constructing paths with IFS=:, quote the path. If we're
7560 constructing a DOS-style absolute path, we don't want to split it
7561 on the colon.
7563 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
7564 in description.
7566 2003-02-25 Pavel Roskin <proski@gnu.org>

7574 2002-09-01 patch by replacing "test -n" with "test -z".
7575 This fixes a bug found by Jeff Painter and reported by Tom Epperly in

7578 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
7579 to fix a mismatch between example and discussion.
7581 2003-02-24 Kevin Ryde <user42@zip.com.au>
7583 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
7584 format starting with "-".
7586 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7588 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
7589 is not portable inside Makefile.
7591 2003-02-20 Akim Demaille <akim@epita.fr>
7593 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
7594 compiler says yeah, but preproc says nope, compiler is right.
7595 Conversely, prompt the reader to send a bug report to the
7596 maintainers of the package, not of Autoconf.
7598 2003-02-20 Klee Dienes <kdienes@apple.com>
7600 * bin/autoreconf.in (autoreconf_current_directory): Properly
7601 handle an empty aclocal.m4.

7605 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Quote
7606 $ac_prefix_program.
7607 From Larry Jones.
7609 2002-12-23 Paul Eggert <eggert@twinsun.com>
7611 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7612 innocuous variant befor including <limits.h> or <assert.h>. This
7613 works around a bug reported by Albert Chin: HP-UX 11i
7614 (and earlier versions) have a <limits.h> that declares
7615 gettimeofday and many other functions.
7617 2002-12-03 Paul Eggert <eggert@twinsun.com>
7619 Version 2.57.
7621 * NEWS, configure.ac: Update version.
7623 * doc/fdl.texi: Upgrade to FDL version 1.2.
7625 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7626 nontrivially in main's body, so that f's external declaration is
7627 not optimized away in AIX. This should fix the bug reported by
7628 Martin Frydl in
7629 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7631 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7632 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7633 defined, to support freestanding compilers. This should fix the
7634 bug reported by Momchil Velkov in
7635 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7637 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
7638 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
7639 obsolete AC_CHECK_TYPE. The missing empty arg was reported
7640 by Simon Josefsson in

7643 * Makefile.maint (www-gnu): New macro.
7644 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
7645 the location has moved.
7647 2002-12-02 Martin Frydl <martin@systinet.com>
7649 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
7650 \(.*\) match is too long and there is something more to be checked.
7651 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
7653 2002-11-15 Akim Demaille <akim@epita.fr>
7655 Version 2.56.
7657 * config/install-sh: chmod +x.
7658 From Paul Eggert.
7659 * config/move-if-change: Indenting changes.
7660 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
7661 * configure.ac (AM_INIT_AUTOMAKE): here.
7662 Require 1.7.1.
7664 2002-11-14 Akim Demaille <akim@epita.fr>
7666 Version 2.55.
7668 * config/config.guess, config/config.sub, config/install-sh:
7669 Update from masters.
7671 2002-11-14 Akim Demaille <akim@epita.fr>
7673 * Makefile.maint: Sync with Bison, i.e.:
7674 (po-check): Scan .l and .y files instead of the
7675 .c and the .h files that they generate. This fixes the bug
7676 reported by Tim Van Holder in:
7677 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7678 Look for N_ as well as for _. Try to avoid matching #define for
7679 N_ and _.
7680 From Paul Eggert.
7682 2002-11-14 Akim Demaille <akim@epita.fr>
7684 * doc/autoconf.texi (C Compiler): Compiling several files at once.
7685 From Paul Eggert and Albert Chin-A-Young.
7687 2002-11-14 Akim Demaille <akim@epita.fr>
7689 * doc/autoconf.texi (C Compiler): Solitary backslashes.
7690 From Paul Eggert and Albert Chin-A-Young.
7692 2002-11-14 Kevin Ryde <user42@zip.com.au>
7694 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
7695 than assigning in main, to avoid HP cc +O3 optimizing it away.
7697 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
7699 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
7700 option. Process --recheck after parsing all options. Pass -q
7701 option to configure on --recheck.
7702 (AC_OUTPUT): Pass -q from configure to config.status.
7703 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
7704 arguments to record.
7705 * doc/autoconf.texi (config.status Invocation): Document
7706 config.status -q option.
7708 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
7710 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
7711 Makefile.in if Makefile.am exists.
7712 (output): Strip `.am' from Makefiles. Don't
7713 output AC_CONFIG_FILES if no Makefiles were found.
7715 2002-11-07 Akim Demaille <akim@epita.fr>
7717 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
7718 (local_updates): New.
7719 * Makefile.maint: Update, from CVS Bison.
7720 (local_updates): New.
7722 2002-11-06 Akim Demaille <akim@epita.fr>
7724 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
7725 declaration in extern "C" too.
7726 Reported by Roberto Bagnara.
7728 2002-11-06 Akim Demaille <akim@epita.fr>
7730 * tests/torture.at (Configuring subdirectories): Don't use grep
7731 -w.
7732 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
7733 Reported by Ezra Peisach.
7735 2002-11-05 Akim Demaille <akim@epita.fr>
7737 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
7738 Remove.
7739 We _have_ to stop using the old compatibility scheme that tried to
7740 avoid useless backslashes because Libtool 1.4.3 contains a
7741 AC_DEFINE([error_t], [int],
7742 [Define to a type to use for \`error_t' if it is not
7743 otherwise available.])
7744 We _have_ to quote the single quote and backslashes with \. The
7745 old compatibility scheme saw that ` was backslashed, and therefore
7746 did not quote the single quote. Hence before this patch, Autoconf
7747 was not compatible with Libtool.
7749 2002-11-04 Paul Eggert <eggert@twinsun.com>
7751 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
7752 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
7753 LC_NAME, LC_PAPER, LC_TELEPHONE.
7754 * doc/autoconf.texi (Special Shell Variables): Mention those vars.
7756 2002-11-04 Akim Demaille <akim@epita.fr>
7758 Version 2.54c.
7760 * Makefile.maint (update, cvs-update, po-update, do-po-update):
7761 New.
7762 * config/texinfo.tex: Update.
7764 2002-11-03 Akim Demaille <akim@epita.fr>
7766 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
7767 from...
7768 (&autoreconf): here.
7769 ($help, $make, &parse_args, &autoreconf_current_directory):

7845 * tests/torture.at (Deep Package): New test.

8079 2002-10-22 Akim Demaille <akim@epita.fr>
8081 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

8085 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
8086 strings.
8088 2002-10-22 Akim Demaille <akim@epita.fr>
8090 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

8137 longer required can still cause errors.
8138 Reported by Alexandre Duret-Lutz.
8140 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
8141 to frozen files in @ARGV, as @ARGV must remain being a list of

8144 (&freeze): Use &error.
8145 (&up_to_date): If a file that was included according to the cache
8146 is no longer there, then the output is out dated.

8148 --force is given.
8149 * tests/tools.at (autom4te cache): New.
8151 2002-10-16 Akim Demaille <akim@epita.fr>

8158 that error messages can be easily located, and use GNU Make
8159 format, so that Emacs' compile mode understands us.
8160 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8161 if some file was changed instead of `print'.
8162 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

8196 file name to enable parallel executions.
8197 From Sam Varshavchik.
8199 2002-10-08 Akim Demaille <akim@epita.fr>
8201 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8202 aclocal invocation, as Gettext macros might not be visible to
8203 aclocal.
8204 Instead of blindly running autopoint, scan configure.ac (not the
8205 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8206 Reported by Paul D. Smith.
8208 2002-10-08 Paul Eggert <eggert@twinsun.com>
8210 Work around problems found when POSIXLY_CORRECT=1 is set.
8211 None of this seems to have anything to do with POSIX, really,
8212 but it's how Perl getopt works.
8213 * bin/autom4te.in (parse_args): Configure GetOpt with
8214 "permute", too.
8215 * doc/autoconf.texi (Invoking autom4te):
8216 --warning -> --warnings.

8238 * tests/torture.at (Configuring subdirectories): Be robust to
8239 users who use config.site to require for a cache: in this case,
8240 the two last configure runs, using two different sets of
8241 arguments, trigger a legitimate error.
8243 2002-09-28 Akim Demaille <akim@epita.fr>

8259 (tm_zone): Move their rules to...
8260 * lib/autoconf/types.m4: here, using AN_ macros.
8261 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
8262 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
8263 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
8264 * lib/autoconf/programs.m4: here.
8265 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)

8267 Use it.
8269 2002-09-28 Akim Demaille <akim@epita.fr>
8271 * lib/autoconf/autoscan.m4: New file.
8272 * lib/autoconf/autoconf.m4: Include it.

8274 that were listed in the original autoscan.list.
8275 * lib/autoconf/headers.m4: Similarly with headers.
8276 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
8277 (.m4.m4f): Don't pass --prepend-include, since that's done by
8278 tests/autom4te itself.
8279 * lib/autoscan/Makefile.am: Include freeze.mk.
8280 (autoscan.list): New target --this file is no longer a source.
8281 (autoscan.pre): New file.
8283 2002-09-28 Akim Demaille <akim@epita.fr>
8285 * bin/autoscan.in (@kinds): Make them singular.
8286 Adjust all uses.
8287 (&init_tables): When --debug, report the list of rules to ease
8288 tracking changes in autoscan.list.
8289 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8291 2002-09-28 Akim Demaille <akim@epita.fr>
8293 * lib/autoscan/functions, lib/autoscan/headers,
8294 * lib/autoscan/identifiers, lib/autoscan/makevars,
8295 * lib/autoscan/programs: Merge into...
8296 * lib/autoscan/autoscan.list: this.
8297 * bin/autoscan.in (&init_tables): Adjust.
8299 2002-09-28 Akim Demaille <akim@epita.fr>
8301 * lib/autoscan/functions, lib/autoscan/headers,
8302 * lib/autoscan/identifiers, lib/autoscan/makevars,
8303 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
8304 `functions' line is now prefixed with `function:'.
8305 * bin/autoscan.in (&init_tables): Adjust.
8307 2002-09-28 Akim Demaille <akim@epita.fr>
8309 From now on, autoscan files must always map a macro name to a
8310 word: there is no `default' macro for autoscan.
8312 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8313 all.
8314 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8315 explicit.
8317 2002-09-28 Akim Demaille <akim@epita.fr>
8319 * bin/autoscan.in (%c_keywords): Remove.
8320 (&used): Keep only track of the words we might be interested in.
8321 (&output_kind): It is no longer needed to look for non active
8322 checks.
8324 2002-09-27 Akim Demaille <akim@epita.fr>
8326 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

8331 2002-09-27 Akim Demaille <akim@epita.fr>
8333 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
8334 from /tmp.
8335 Thanks to Bill Moseley and Paul Eggert.
8336 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
8337 the tmpdir must be created.
8338 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
8339 dir be in the build tree, instead of $TMPDIR.
8341 2002-09-27 Akim Demaille <akim@epita.fr>
8343 * bin/autoscan.in: Improve the comments.
8344 (&parse_args): Drop obsolete undocumented options.
8345 (&output_kind): Output warnings.
8346 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

8352 Reported by Ralf Corsepius.
8353 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8355 2002-09-26 Akim Demaille <akim@epita.fr>
8357 Single suffix rules and seperated dependencies are not portable.
8359 * doc/autoconf.texi (Installation Directory Variables): Update.
8360 (Limitations of Make): Some about `Single Suffix Rules and
8361 Separated Dependencies'.
8362 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8363 (ifnames, autoscan, autom4te): Un-factor into several rules.
8365 2002-09-25 Paul Eggert <eggert@twinsun.com>
8367 * BUGS (Interoperability bugs): New section. Mention libtool
8368 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
8370 2002-09-24 Paul Eggert <eggert@twinsun.com>
8372 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
8373 make handles suffix-rules differently from GNU make.
8375 * bin/Makefile.am (SUFFIXES, .in): Remove.
8376 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
8377 Move the body of the old .in rule here.
8379 2002-09-16 Akim Demaille <akim@epita.fr>
8381 i960 compilers create `b.out' files by default.
8382 Reported by Ralf Corsepius.
8384 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
8385 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
8387 2002-09-13 Paul Eggert <eggert@twinsun.com>
8389 * doc/autoconf.texi (Particular Headers): Remove obsolete
8390 reference to `struct timezone' in the description of
8391 AC_HEADER_TIME.
8393 2002-09-13 Akim Demaille <akim@epita.fr>
8395 Version 2.54.
8397 * config/config.sub, config/config.guess: Update.
8398 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
8399 * Makefile.am: Adjust.
8401 2002-09-13 Akim Demaille <akim@epita.fr>
8403 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
8404 reading config.log when the compiler is rejected.
8405 Suggested by Guido Draheim.
8407 2002-09-13 Akim Demaille <akim@epita.fr>
8409 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8410 (chdir_init) might hang when stat'ing mounted directories.
8411 Reported by Vance Shipley.
8413 2002-09-12 Akim Demaille <akim@epita.fr>
8415 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8416 the lists.
8418 2002-09-12 Akim Demaille <akim@epita.fr>
8420 * doc/autoconf.texi (Defining Symbols): Present two different
8421 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
8422 difference between 1 argument calls, and 2-3 argument calls.
8424 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
8426 * doc/autoconf.texi: Review grammar and punctuation.
8428 2002-09-11 Paul Eggert <eggert@twinsun.com>
8430 * doc/autoconf.texi: Fix minor formatting, spelling, and
8431 grammatical typos.
8432 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8433 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8434 is obsolescent.
8436 2002-09-11 Akim Demaille <akim@epita.fr>
8438 * doc/autoconf.texi (Questions): Rename as...
8439 (FAQ): this.
8440 (Defining Directories): New.
8442 2002-09-09 Akim Demaille <akim@epita.fr>
8444 * doc/autoconf.texi (Making testsuite Scripts): Update.
8445 Suggested by Nishio Futoshi.
8447 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8449 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8450 plain `@' is wanted.
8452 2002-09-09 Akim Demaille <akim@epita.fr>
8454 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8455 `duplicates', since the algorithm was too naive and could keep
8456 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8457 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8458 Reported by Ralf Corsepius.
8459 * tests/torture.at (Configuring subdirectories): Exercise these
8460 cases.
8462 2002-09-09 Akim Demaille <akim@epita.fr>
8464 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
8465 looking for a replacement file.
8466 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8467 directory is relative.
8468 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8469 directory definition.
8470 Reported by Andreas Schwab and Jim Meyering.
8472 2002-09-06 Akim Demaille <akim@epita.fr>
8474 * doc/autoconf.texi (Setting Output Variables): Clarify what
8475 precious variables are.
8476 Suggested by Pontus Skoeld.
8478 2002-09-05 Akim Demaille <akim@epita.fr>
8480 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8481 (ifnames, autoscan, autom4te): Since we don't only depend on
8482 configure.ac variables (such as VERSION etc.), but also on prefix
8483 and so forth, depend on Makefile, not configure.ac.
8484 Reported by Alexandre Duret-Lutz.
8485 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8487 2002-09-05 Kevin Ryde <user42@zip.com.au>
8489 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8490 doesn't seem to be confined to ia64, just say "some versions".
8492 2002-09-04 Akim Demaille <akim@epita.fr>
8494 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8495 Automake 1.6c.
8496 * Makefile.am (maintainer-clean-local): Remove.
8497 (MAINTAINERCLEANFILES): Remove COPYING.
8499 2002-09-03 Paul Eggert <eggert@twinsun.com>
8501 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8502 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8503 Brinkmann.
8505 2002-09-03 Akim Demaille <akim@epita.fr>
8507 * configure.ac: Bump to 2.53d.
8508 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8509 as of today, on Automake's team suggestion.
8511 2002-09-03 Akim Demaille <akim@epita.fr>
8513 Version 2.53c.
8515 2002-09-02 Akim Demaille <akim@epita.fr>
8517 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8518 SITE_MACRO_DIR.
8519 * configure.ac: Disable SITE_MACRO_DIR.
8521 2002-09-02 Jim Meyering <meyering@lucent.com>
8523 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8524 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8525 Also, tweak grammar: s/make sure to/be sure to/.
8527 2002-09-02 Paul Eggert <eggert@twinsun.com>
8529 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8530 directory names are generally preferable to physical names.
8532 2002-09-02 Akim Demaille <akim@epita.fr>
8534 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8535 Reported by Raja R. Harinath.
8536 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8537 * bin/autoupdate.in: Use error instead of die.
8539 2002-09-01 Paul Eggert <eggert@twinsun.com>
8541 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8542 ordinary shell concatenation rather than echo+tr+sed command that
8543 runs afoul of a long-line-related sed bug in Solaris 8.
8545 * bin/autoheader.in (parse_args): --warning -> --warnings.
8547 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8548 stdout, as traditional "ls" does.
8549 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8550 _AC_COMPILER_EXEEXT_O): Likewise.
8551 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8553 * bin/autoconf.as: Add --prepend-include option. This patch was
8554 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8555 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8557 * bin/autoconf.in, configure: Regenerate.
8559 * doc/autoconf.texi (Special Shell Variables): Mention
8560 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8562 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8563 MAILPATH and set PS1, PS2, PS4 to default values, to work
8564 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8565 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8566 the Autoconf documentation specifies; fall back to "unset" only if
8567 this fails. Use a shell for-loop for this rather than an m4 loop,
8568 to shorten the output script.
8570 2002-08-30 Paul Eggert <eggert@twinsun.com>
8572 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8573 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8574 for the CDPATH problem. Document PWD.
8575 (Limitations of Builtins): Document the problem that "cd $foo" and
8576 "ls $foo" may refer to different directories in shells conforming
8577 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8578 example, since the old example is now out of date.
8580 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8581 FOO" and "ls FOO" talk about different directories; this catches
8582 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8583 spaghetti.
8585 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8586 of rolling our own unset.
8587 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8588 in practice we needn't worry about CDPATH if unset doesn't work.
8590 * Makefile.in, aclocal.m4, bin/Makefile.in,
8591 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8592 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8593 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8594 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8595 tests/Makefile.in: Regenerate with Automake 1.6.3.
8597 * config/config.guess, config/config.sub, config/mkinstalldirs:
8598 Update.
8600 * configure: Regenerate with self.
8602 2002-08-30 Kevin Ryde <user42@zip.com.au>
8604 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8605 default output.
8607 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8609 * bin/autom4te.in (Request::load): Correctly test for "do" read
8610 failure.
8612 2002-08-29 Akim Demaille <akim@epita.fr>
8614 * lib/Autom4te/General.pm (&xqx): New.
8615 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8616 hand, which is not portable.
8617 (&error): New.
8618 * bin/autom4te.in: Use them.
8619 Use &error instead of die.
8620 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8621 Adjust.
8623 2002-08-17 Paul Eggert <eggert@twinsun.com>
8625 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8626 default list of compilers to try, since it was long ago superseded
8627 by the ksh fc builtin. Suggested by Steven G. Johnson.
8629 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8631 * doc/autoconf.texi (Invoking autom4te): End the option table,
8632 fixing a bug introduced by the previous patch.
8633 (Limitations of Make): Add a 'target lookup' subentry in the
8634 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8636 2002-07-29 Mark D. Roth <roth@feep.net>
8638 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8639 options and use $AUTOM4TE_PATH.
8640 * doc/autoconf.texi: Remove documentation of autom4te
8641 --include-envvar and --site-macro-subdir options and document
8642 use of $AUTOM4TE_PATH.
8643 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8644 arguments from each language section.
8646 2002-07-29 Paul Eggert <eggert@twinsun.com>
8648 * doc/install.texi: Include copyright symbol in copyright notice.
8650 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8651 Replace with:
8652 (AM_MAKEINFOFLAGS): New macro.
8653 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8654 * Makefile.am (INSTALL): Use the new macros.
8655 Use -o rather than --output, since "missing" does not grok --output.
8657 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8659 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8660 comments do not always work. Never trust the exit status of
8661 `make -k'.
8663 2002-07-24 Kevin Ryde <user42@zip.com.au>
8665 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8666 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8668 2002-07-23 Paul Eggert <eggert@twinsun.com>
8670 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8671 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8672 apparently treats PATH="nonexistent" as if it contained ".".
8673 Bug reported by Stefan `Sec' Zehl.
8675 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8677 * doc/autoconf.texi (Limitations of Make): Mention the special
8678 handling of the obj/ directory by BSD make.
8680 2002-07-20 Kevin Ryde <user42@zip.com.au>
8682 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
8683 backslashes.
8685 2002-07-19 Akim Demaille <akim@epita.fr>
8687 * doc/autoconf.texi (Function Portability): `exit'.
8688 (Programming in M4sh): Ethymology of M4sh.
8690 2002-07-19 Akim Demaille <akim@epita.fr>
8692 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
8694 2002-07-18 Akim Demaille <akim@epita.fr>
8696 Version 2.53b.
8698 2002-07-18 Akim Demaille <akim@epita.fr>
8700 * config/config.guess, config/config.sub: Update.
8702 2002-07-18 Akim Demaille <akim@epita.fr>
8704 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
8705 Automake's parts.
8707 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
8708 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
8709 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
8711 2002-07-18 Akim Demaille <akim@epita.fr>,
8712 Alexandre Duret-Lutz <duret_g@epita.fr>
8714 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
8715 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
8717 2002-07-17 Russ Allbery <rra@stanford.edu>
8719 * doc/autoconf.texi (Initializing configure): Clarify the
8720 description of the tarname default.
8722 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
8724 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
8725 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
8726 latter was not run.
8728 2002-07-17 Akim Demaille <akim@epita.fr>
8730 * lib/Autom4te/General.pm (find_file): Browse the directories in
8731 the order they are given.
8733 2002-07-17 Akim Demaille <akim@epita.fr>
8735 * tests/wrapsh.as, tests/wrappl.as: Merge into...
8736 * tests/wrapper.as: this.
8737 * tests/Makefile.am, configure.ac: Adjust.
8739 2002-07-17 Mark D. Roth <roth@feep.net>
8741 * configure.ac: Add --enable-site-macro-dir option.
8742 * bin/Makefile.am: Expand @SITE_MACRO_DIR@.
8743 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
8744 --site-macro-subdir options.
8745 * bin/autoconf.in: Add --prepend-include option.
8746 * bin/autoheader.in: Add --prepend-include option.
8747 * bin/autoreconf.in: Add --prepend-include option.
8748 * bin/autoscan.in: Add --prepend-include option.
8749 * bin/autoupdate.in: Add --prepend-include option.
8750 * doc/autoconf.texi: Document use of $AC_MACRO_PATH and site
8751 macro directory, remove note that include path directories are
8752 used in reverse order, and document --prepend-include option.

8799 2002-06-27 Paul Eggert <eggert@twinsun.com>
8801 * config/install-sh: Quote $src. Prefer || to test's -o option,
8802 as per "Limitations of Builtins".
8803 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
8804 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.

8834 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>

8837 of the cache should not depend on the name under which autom4te
8838 was installed.
8840 2002-06-07 Akim Demaille <akim@epita.fr>

8846 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
8848 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
8849 _AC_LANG_PROGRAM_C_F77_HOOKS.
8851 2002-06-07 Akim Demaille <akim@epita.fr>

8856 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
8857 AC_FUNC_FNMATCH_GNU.
8859 2002-06-07 Akim Demaille <akim@epita.fr>
8861 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
8862 Rosetta Stone for Unix.
8864 2002-06-07 Akim Demaille <akim@epita.fr>
8866 * bin/autom4te.in (warn_forbidden): When rejecting a token,
8867 suggest m4_pattern_allow.
8868 Suggested by Adam J. Richter.
8870 2002-06-07 Akim Demaille <akim@epita.fr>
8872 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize

8875 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

8929 version of Autoconf that is discussed.
8931 2002-05-22 Paul Eggert <eggert@twinsun.com>
8933 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
8934 from the default list of compilers to try. Suggested by
8935 Kate Hedstrom.
8936 * NEWS: Document the above.
8937 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
8939 2002-05-17 Paul Eggert <eggert@twinsun.com>
8941 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
8942 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
8943 This improves on an earlier suggestion by H. Peter Anvin.
8945 2002-05-16 Paul Eggert <eggert@twinsun.com>
8947 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
8948 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
8949 Both macros now accept an optional source-dir arg.
8950 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
8952 * NEWS: Document this.
8953 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
8955 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
8956 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
8957 not for GNU extensions; this undoes part of the 2000-11-03 change,
8958 reverting to 2.13-compatible behavior.
8959 Add new optional argument DIR.
8960 (AC_FUNC_FNMATCH_GNU): New macro.
8962 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
8964 2002-05-08 Paul Eggert <eggert@twinsun.com>
8966 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
8967 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
8968 and it causes a 'test' syntax error if it fails.
8969 Bug reported by Stephen Gildea.
8971 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8972 If prototypes are supported, use them to check this at compile-time,
8973 instead of trying to check it at run-time. If we must do a run-time
8974 check, assume that setvbuf is standard when cross-compiling, as
8975 nonstandard setvbuf occurs only on ancient and unlikely hosts.
8976 Bug reported by Paul D. Smith.
8978 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
8979 argument specifying location of getloadavg.c. This removes a
8980 FIXME. This idea was taken from Jim Meyering's implementation in
8981 textutils.
8982 * doc/autoconf.texi (Particular Functions): Document this.
8983 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
8984 that's what the code does; this fixes a bug reported by
8985 Paul D. Smith.
8987 2002-05-03 Akim Demaille <akim@epita.fr>
8989 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
8990 autopoint instead of gettextize.
8991 ($uses_alocal): Rename as...
8992 ($uses_aclocal): this.
8993 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8994 Suggested by Bruno Haible.
8996 2002-05-03 Akim Demaille <akim@epita.fr>
8998 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9000 2002-04-29 Paul Eggert <eggert@twinsun.com>
9002 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9003 files to be 1 second older; just set them to be the same time.
9004 Also, sleep 1 second after the first aclocal, to work around
9005 problems with sub-second time stamps on the input files.
9007 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9009 * doc/autoconf.texi: Mention "set -e -x" lossage
9010 under node "Limitations of Builtins".
9012 2002-04-29 Akim Demaille <akim@epita.fr>
9014 * doc/install.texi: Better wording for setting variables when
9015 running configure.
9016 From Christian Cornelssen.
9018 2002-04-29 Akim Demaille <akim@epita.fr>
9020 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9021 of lack of $LINENO support, then the test will compare the $LINENO
9022 in testsuite vs. the lineno in the test file. This is wrong, of
9023 course.
9024 Be sure to protect it.
9025 Reported by Patrick Welche.
9027 2002-04-25 Akim Demaille <akim@epita.fr>
9029 * doc/autoconf.texi (Obsolete Macros): Typo.
9030 Reported by Vladimir Volovich.
9032 2002-04-25 Akim Demaille <akim@epita.fr>
9034 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9035 than some of the input files, hence, on the second run of aclocal,
9036 if some of its input are younger, make them older.
9037 Suggested by Paul Eggert.
9039 2002-04-25 Akim Demaille <akim@epita.fr>
9041 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9042 Thanks to Paul Eggert.
9044 2002-04-25 Akim Demaille <akim@epita.fr>
9046 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9047 and ac_subst_vars be sh variables containing the list of
9048 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9049 DEFAULT diversion.
9050 (_AC_INIT_PREPARE): Use them to log them.
9051 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9052 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9053 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9054 _AC_SUBST_FILES and _AC_SUBST_VARS.
9055 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9057 2002-04-24 Akim Demaille <akim@epita.fr>
9059 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9060 autoheader, so that automake does not complain about a missing
9061 config.h.in that was to be created.
9063 2002-04-23 Akim Demaille <akim@epita.fr>
9065 * bin/autoheader.in (parse_args): --warning takes an argument.
9066 Fixes PR/220.
9068 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
9070 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

9115 Minor spelling and grammar fixes.
9117 * doc/autoconf.texi: Follow the outline suggested in the GNU
9118 Sample Texts sections of the Texinfo 4.2 manual. Most
9119 importantly, this makes sure that the copyright notices appear in
9120 all output formats. You probably need Texinfo 4.2 to generate
9121 the manual now.

9147 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
9149 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

9176 * lib/autotest/general.m4 (AT_INIT): Likewise.
9177 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

9181 Use this M4sh to generate Autoconf's shell scripts.
9183 * tests/wrapsh.as: New, precursor of wrapsh.in.

9226 Don't use the KILL diversion, as it kills spurious output, which
9227 results in failures being hidden.

9238 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
9239 expanded if $# <= 2.

9242 aclocal.
9244 2002-04-03 Akim Demaille <akim@epita.fr>
9246 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
9247 (_AC_COMPILER_EXEEXT_REJECT): New.
9248 Also recognize *.bb and *.bbg as compilation byproducts.
9249 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
9250 (_AC_COMPILER_OBJEXT): Use them.
9251 Fixes Debian #138666.
9253 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9255 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
9257 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
9258 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9259 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
9260 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
9261 (AC_C_CONST): Same.
9262 (AC_C_INLINE): Same.
9263 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
9264 * doc/autoconf.texi, NEWS: Document.
9265 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
9266 AC_C_CROSS.
9268 2002-04-02 Akim Demaille <akim@epita.fr>
9270 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
9271 _AS_MKDIR_P_PREPARE.
9273 2002-03-28 Kevin Ryde <user42@zip.com.au>
9275 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9276 to avoid versions of HP C which don't allow that.
9278 2002-03-27 Paul Eggert <eggert@twinsun.com>
9280 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9281 (AS_SHELL_SANITIZE): Invoke it.
9282 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
9284 2002-03-26 Akim Demaille <akim@epita.fr>
9286 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
9288 2002-03-26 Akim Demaille <akim@epita.fr>
9290 * doc/autoconf.texi (Introduction): The GNATS base moved.
9292 2002-03-25 Paul Eggert <eggert@twinsun.com>
9294 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9295 as POSIX requires, as it doesn't work with Zsh.
9296 * doc/autoconf.texi (Assignments): Document the problem.
9298 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9300 * doc/autoconf.texi (Limitations of Make): Mention more issue
9301 about VPATH, overriding of macros in sub-makes, and handling of
9302 SHELL.
9304 2002-03-21 Paul Eggert <eggert@twinsun.com>
9306 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9307 problem with here-document buffer boundaries.
9309 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9310 when reinvoking the shell, to work around problems with installers
9311 who put strange things like "cd" commands in their environments.
9313 2002-03-19 Akim Demaille <akim@epita.fr>
9315 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9316 From Aaron Ucko.
9318 2002-03-19 Akim Demaille <akim@epita.fr>
9320 * bin/autoscan.in (scan_file): Specify the location in `&used'
9321 invocations.
9322 From Nicolas Joly.
9324 2002-03-19 Akim Demaille <akim@epita.fr>
9326 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
9327 From Nishio Futoshi.
9329 2002-03-19 Akim Demaille <akim@epita.fr>
9331 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9333 2002-03-18 Paul Eggert <eggert@twinsun.com>
9335 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9336 (Limitations of Usual Tools): Add mkdir section.
9338 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9339 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9340 back on AS_DIRNAME to compute prefixes otherwise; this is
9341 roughly what mkinstalldirs does. That way, we need not have
9342 our own filename disassembler. The old disassembler did not
9343 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9345 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9346 Create at_test_all by a series of assignments,
9347 not by a single assignment of a long string. The latter causes ksh
9348 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9349 presumably because of a buffer overrun.
9351 2002-03-14 Paul Eggert <eggert@twinsun.com>
9353 * lib/autotest/general.m4 (at_times_skip):
9354 Renamed from at_times. Now a boolean.
9355 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9356 says 'times: not found'.
9358 2002-03-14 Akim Demaille <akim@epita.fr>
9360 * bin/autoreconf.in (&study_gettextize): New.
9361 (&autoreconf): Handle newest gettextize.
9362 Rerun aclocal if needed.
9363 Suggested by Andreas Schwab.
9365 2002-03-13 Akim Demaille <akim@epita.fr>
9367 * doc/autoconf.texi (Special Shell Variables): More about IFS.
9369 2002-03-13 Akim Demaille <akim@epita.fr>
9371 * doc/autoconf.texi (Header Portability): New.
9372 Add information about stdint.h and inttypes.h from Paul Eggert.
9374 2002-03-13 Akim Demaille <akim@epita.fr>
9376 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9377 -p'.
9378 From Bob Proulx.
9380 2002-03-12 Akim Demaille <akim@epita.fr>
9382 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9383 m4_require.
9385 2002-03-11 Andreas Schwab <schwab@suse.de>
9387 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9388 does not do it if --with-lispdir is given.
9390 2002-03-08 Akim Demaille <akim@epita.fr>
9392 Version 2.53.
9394 2002-03-08 Akim Demaille <akim@epita.fr>
9396 * doc/autoconf.texi (Subdirectories): Clarify that the
9397 subdirectory should exist.
9399 2002-03-08 Akim Demaille <akim@epita.fr>
9401 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9403 2002-03-08 Akim Demaille <akim@epita.fr>
9405 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9406 aliases the actual variables, and modifications of the former
9407 affect the latter.
9409 2002-03-08 Akim Demaille <akim@epita.fr>
9411 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9412 because of C-c: have m4 output in tmp files, then mv them.
9414 2002-03-08 Akim Demaille <akim@epita.fr>
9416 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
9417 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
9418 * bin/ifnames.in: Copyright update.
9420 2002-03-08 Akim Demaille <akim@epita.fr>
9422 * doc/autoconf.texi (Invoking autom4te): New.
9424 2002-03-05 Akim Demaille <akim@epita.fr>
9426 * doc/autoconf.texi (Specifying Names): Clarification suggested by
9427 Kevin Ryde.
9429 2002-03-05 Akim Demaille <akim@epita.fr>
9431 Version 2.52i.
9433 2002-03-04 Akim Demaille <akim@epita.fr>
9435 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
9436 * lib/autoconf/general.m4 (AC_INIT): More informative error
9437 message for LIBOBJ.
9439 2002-03-04 Akim Demaille <akim@epita.fr>
9441 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
9442 parallel builds.
9444 2002-03-04 Akim Demaille <akim@epita.fr>
9446 * doc/autoconf.texi (Transforming Names): Equality between target
9447 and host is irrelevant.
9448 (Specifying Names, Canonicalizing): Remove all references to the
9449 backward compatibility hooks. Rather, collect them all into...
9450 (Hosts and Cross-Compilation): this new section.
9451 * doc/install.texi (System Type): Ditto.
9452 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9453 that `--host' implies cross-compilation.
9455 2002-03-04 Akim Demaille <akim@epita.fr>
9457 * doc/autoconf.texi (Evaluation Macros): New.
9458 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9459 useless.
9460 (_m4_foreach): Define the variant with immediate evaluation so
9461 that it contains exactly the items, not an expression which
9462 evaluation is the current item.
9463 (m4_re_string, m4_re_word): Don't over quote them.
9465 2002-03-04 Akim Demaille <akim@epita.fr>
9467 Instead of having stacking `shift's evaluated at the end, let
9468 `foreach' loops immediately evaluate them.
9470 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9471 $*. This is the n-th time I change my mind, but hopefully this is
9472 the last...
9473 (m4_lquote): New.
9474 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9475 efficient.
9476 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9477 it was only a hack for m4_text_wrap.
9478 (m4_car2): Remove, replaced by...
9479 (m4_cdr): New.
9480 (_m4_foreach): Adjust.
9481 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9482 m4_bpatsubst for clarification.
9484 2002-03-04 Akim Demaille <akim@epita.fr>
9486 * doc/autoconf.texi (Changequote is Evil): New.
9488 2002-03-03 Kevin Ryde <user42@zip.com.au>
9490 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
9491 on old systems like SunOS.
9493 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
9495 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9496 lib/autoconf/functions.m4, lib/autoconf/general.m4,

9504 message to be sent.
9506 2002-02-28 Kevin Ryde <user42@zip.com.au>

9510 2002-02-25 Akim Demaille <akim@epita.fr>
9512 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
9513 From Akinori Musha.
9515 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
9517 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
9518 translate \r\n to \n.
9520 2002-02-07 Akim Demaille <akim@epita.fr>
9522 Version 2.52h.
9524 2002-02-07 Akim Demaille <akim@epita.fr>
9526 Fix Autoconf PR/209.
9527 Also reported by Frank Denis.
9529 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
9531 2002-02-07 Akim Demaille <akim@epita.fr>
9533 Fix Autoconf PR/207:
9534 AC_PREFIX_PROGRAM fails with dashed program names
9536 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
9537 variable when looking for the prefix program.
9538 Now it also works for shell variables.
9540 2002-02-07 Akim Demaille <akim@epita.fr>
9542 * doc/autoconf.texi (Limitations of Builtins): More about
9543 case/esac.
9545 2002-02-06 Akim Demaille <akim@epita.fr>
9547 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
9548 case/esac, some shells don't support it.
9549 Reported by Zack Weinberg.
9550 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
9552 2002-02-06 Akim Demaille <akim@epita.fr>
9554 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
9555 sure not to introduce newlines in at_groups.
9556 * lib/autotest/Makefile.am (autotest.m4f): Typo.
9558 2002-02-06 Akim Demaille <akim@epita.fr>
9560 * tests/torture.at (Configuring subdirectories): Skip if aclocal
9561 is not available.
9563 2002-02-05 Paul Eggert <eggert@twinsun.com>
9565 * doc/autoconf.texi (Specific Compiler Characteristics):
9566 Describe HP-UX cc bug workaround more accurately.
9567 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
9568 not unsigned long.
9569 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
9570 cross-compilers, too. This undoes some of the most recent change
9571 to this file.
9573 2002-02-05 Akim Demaille <akim@epita.fr>
9575 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
9576 to make sure they are up to date when `check' is run.
9578 2002-02-05 Akim Demaille <akim@epita.fr>
9580 * doc/autoconf.texi (Making testsuite Scripts): Document
9581 package.m4.
9583 2002-02-05 Akim Demaille <akim@epita.fr>
9585 * lib/freeze.mk: New.
9587 2002-02-05 Akim Demaille <akim@epita.fr>
9589 Implement `autom4te --freeze'.
9591 * bin/autom4te.in (&freeze): New.
9592 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9593 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9595 2002-02-05 Akim Demaille <akim@epita.fr>
9597 * bin/autom4te.in (&parse_args): Implement `frozen files are
9598 optional are the sum of the previous files on the command line'.
9599 Also, pass `--reload-state=' on them, so...
9600 (handle_m4): don't.
9601 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9602 (M4sh): Rely on M4sugar.
9603 (Autotest, M4sh, M4sugar): Use frozen files.
9605 2002-01-31 Akim Demaille <akim@epita.fr>
9607 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
9608 * doc/autoconf.texi (Initializing configure): Adjust.
9610 2002-01-30 Akim Demaille <akim@epita.fr>
9612 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
9613 alphanumeric to `-' instead of `_'.
9615 2002-01-30 Akim Demaille <akim@epita.fr>
9617 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
9618 for plain code, the other for cross-compilation code. The latter
9619 is now run with GCC only.
9620 * doc/autoconf.texi (Compilers and Preprocessors): New.
9622 2002-01-30 Akim Demaille <akim@epita.fr>
9624 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
9625 values.
9626 * doc/autoconf.texi (Initializing configure): Explain how to
9627 change AC_INIT default values.
9629 2002-01-29 Akim Demaille <akim@epita.fr>
9631 * tests/torture.at (Configuring subdirectories): Use configure.in,
9632 so that aclocal 1.4 works.
9633 Reported by Alexandre Duret-Lutz and Larry Schmitt.
9635 2002-01-28 Akim Demaille <akim@epita.fr>
9637 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9638 needs an argument.
9640 2002-01-28 Akim Demaille <akim@epita.fr>
9642 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9643 AUTOTEST_PATH *after* it was set.
9644 Don't put `.' in the PATH: the user should be precise and `./' if
9645 needed. In addition, given that the test suite does some `cd', if
9646 `.' is in the path, the `tested programs' sections will report
9647 programs found in the test suite's directory, while during the
9648 tests (performed in their own directory), these programs are no
9649 longer visible. In other words, the results is confusing and
9650 useless.
9651 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
9653 2002-01-24 Akim Demaille <akim@epita.fr>
9655 Version 2.52g.
9657 2002-01-24 Akim Demaille <akim@epita.fr>

9660 * doc/autoconf.texi: Finally add Akim as an author.
9662 2002-01-24 Akim Demaille <akim@epita.fr>
9664 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
9665 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
9666 Bourne. Use /bin/sh.
9667 From Andreas Buening.
9669 2002-01-24 Akim Demaille <akim@epita.fr>
9671 * config/config.guess, config/config.sub, config/texinfo.tex:

9680 * config/strip.m4: Remove, to ease sync'ing with any version of
9681 Automake.
9683 2002-01-24 Akim Demaille <akim@epita.fr>
9685 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
9686 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
9687 Reported by Geir Ove Myhr.
9689 2002-01-21 Akim Demaille <akim@epita.fr>
9691 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
9693 2002-01-21 Akim Demaille <akim@epita.fr>
9695 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
9696 message on invalid options.
9697 * bin/autom4te.in (parse_args): Don't use
9698 Autoconf::General::getopt with non valid options.
9700 2002-01-17 Jim Meyering <meyering@lucent.com>
9702 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
9703 $ac_cv_exeext so we don't use an old, invalid, cached value.
9705 2002-01-11 Akim Demaille <akim@epita.fr>
9707 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
9708 Meyering.
9709 * doc/autoconf.texi (Function Portability): Document the strnlen
9710 limitation.

9712 * lib/autoscan/functions: Adjust.
9714 2002-01-06 Akim Demaille <akim@epita.fr>
9716 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
9717 package.m4, since is really depends upon configure.ac, not
9718 configure.
9719 * doc/autoconf.texi (testsuite Scripts): Adjust.
9720 * tests/Makefile.am (package.m4): New.
9721 EXTRA_DIST it since its a source.
9723 2002-01-06 Akim Demaille <akim@epita.fr>
9725 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
9726 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
9727 and PACKAGE_BUGREPORT from here...
9728 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
9729 arguments.
9730 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
9731 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
9732 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
9733 * tests/tools.at (autoheader): Adjust.
9734 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
9736 2002-01-06 Akim Demaille <akim@epita.fr>
9738 * bin/autoscan.in (scan_file): Use `&used'.
9740 2002-01-03 Akim Demaille <akim@epita.fr>
9742 * doc/autoconf.texi (Output): Improved wording regarding use of
9743 AC_OUTPUT.
9744 From Olly Betts.
9746 2001-12-18 Kevin Ryde <user42@zip.com.au>
9748 * doc/autoconf.texi (Function Portability): Add notes on sscanf
9749 sometimes needing writable input.
9751 2001-12-17 Jim Meyering <meyering@lucent.com>
9753 * doc/autoconf.texi (New Macros): Tweak wording.
9755 2001-12-14 Akim Demaille <akim@epita.fr>
9757 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
9758 trailing files, don't apply `-rf' to files which might not be
9759 created by configure (core, core.*, and *.core), but just `rm -f'.
9760 Suggested by Jonathan Kamens.
9762 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
9764 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
9766 2001-12-14 Akim Demaille <akim@epita.fr>
9768 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
9770 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
9772 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
9773 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
9774 abs_srcdir, top_srcpath to abs_top_srcdir.
9775 (_AC_OUTPUT_FILES): Adjust.
9776 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
9777 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
9778 * tests/wrappl.in, tests/wrapsh.in: Adjust.
9780 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
9782 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
9783 C/Fortran linking on HP/UX, by extracting the Fortran library
9784 search path from the LPATH line in the $F77 -v output.
9786 2001-12-12 Kevin Ryde <user42@zip.com.au>
9788 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
9789 forbidden file descriptors table.
9791 2001-11-26 Akim Demaille <akim@epita.fr>
9793 * bin/autoscan.in (%c_keywords): Build it at top level.
9794 Map to 1 in order to simplify its uses.
9796 2001-11-26 Akim Demaille <akim@epita.fr>
9798 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
9799 Remove $filepath, useless.
9800 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
9801 variables, they are really part of the tokens.
9802 Split the input line on spaces and then look for tokens.
9803 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
9804 because of `lex$U.$(OBJEXT)'.
9805 (&scan_files): Use "@list" instead of join.
9806 * doc/Makefile.am (CLEANFILES): Add *.fns.
9808 2001-11-26 Akim Demaille <akim@epita.fr>
9810 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
9811 Remove, replaced by...
9812 * tests/wrappl.in: Be common for all the Perl executables.
9813 In particular autoscan and autoheader want -I.
9814 * configure.ac: Adjust.
9815 * lib/autoscan/headers: errno.h is portable.
9817 2001-11-26 Akim Demaille <akim@epita.fr>
9819 * bin/autoscan.in (used): New.
9820 Use it.
9822 2001-11-26 Akim Demaille <akim@epita.fr>
9824 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
9825 directives.
9826 (&scan_sh_file): Remove a duplicate pattern.
9827 (&check_configure_ac): Use long options.
9828 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
9830 2001-11-26 Akim Demaille <akim@epita.fr>
9832 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
9833 Before, having a line containing the opening of a multi line
9834 comment made the whole line be ignored.
9836 2001-11-26 Akim Demaille <akim@epita.fr>
9838 * doc/autoconf.texi (Using an Autotest Test Suite): New.
9839 (testsuite Scripts): Be one of its subsection.
9840 (Autotest Logs): New.
9842 2001-11-26 Akim Demaille <akim@epita.fr>
9844 Test groups are now run two directories deeper.
9846 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
9847 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
9848 at_top_builddir.
9849 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
9850 top_srcdir, builddir and top_builddir.
9851 Use `at_*dir' relatively to the directory containing the
9852 suite, use `*dir' when relatively to the current group dir.
9854 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
9856 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
9857 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
9858 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
9859 spelling errors.
9861 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9863 * doc/autoconf.texi (Using System Type): Add an example of `case
9864 $host' usage so people quit using `case $target' everywhere.
9866 2001-11-22 Akim Demaille <akim@epita.fr>
9868 * doc/autoconf.texi (Installation Directory Variables): Englishoes
9869 spotted by Jim Meyering.
9871 2001-11-16 Paul Eggert <eggert@twinsun.com>
9873 This patch implements a `long double' suggestion by Oliver Kiddle.
9875 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
9876 static, to catch errors if the value isn't known at compile-time
9877 and the compiler supports dynamic arrays. Change its name from
9878 `_array_' to `test_array' to avoid potential name clashes.
9879 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
9880 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
9881 better than double. Catch a bug in GCC 2.95.2 x86.
9882 * doc/autoconf.texi (C Compiler): Document the above.
9883 * NEWS: Likewise.
9885 2001-11-13 Akim Demaille <akim@epita.fr>
9887 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
9888 hand.
9889 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
9891 2001-11-13 Akim Demaille <akim@epita.fr>
9893 * lib/autotest/general.m4 (AT_INIT): After having run the test
9894 group, go back to the initial directory, not to at_suite_dir.
9896 2001-11-13 Akim Demaille <akim@epita.fr>
9898 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
9899 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
9900 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
9901 option.
9902 (AT_CHECK_CONFIGURE): Use absolute paths.
9903 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
9904 The problem is still the old one: there is no means in M4 (that I
9905 know about) to create a defining macro, because there is no means
9906 to create `$1' etc., therefore, the defining macro ``swallows''
9907 all the arguments meant to the defined macro.
9909 2001-11-13 Akim Demaille <akim@epita.fr>
9911 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
9912 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
9913 configure.ac.
9914 * tests/aclocal.m4: Remove, as it is no longer used.
9916 2001-11-13 Akim Demaille <akim@epita.fr>
9918 * lib/autotest/general.m4: Change `tests?' into `groups?' in
9919 variable names when referring to a single test group, or to
9920 `suite' when referring to the whole test suite.
9921 `at_last_test' is removed: m4 compute at_format itself.
9922 (at_stdout, at_stder1, at_stderr): New variables.
9923 (AT_CHECK): Use them.
9925 2001-11-13 Akim Demaille <akim@epita.fr>
9927 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
9928 in PATH.
9929 Create `testsuite.dir/003/run' instead of `testsuite.003'.
9930 Do it as soon as a test fails, don't wait till the end of the test
9931 suite.
9932 Don't remove $as_me.[0-9]*, since these files no longer exist.
9934 2001-11-13 Akim Demaille <akim@epita.fr>
9936 * tests/tools.at: Use absolute paths, since we are no longer run
9937 in place.
9939 2001-11-13 Akim Demaille <akim@epita.fr>
9941 Now that tests are running in their own private dir, there is no
9942 need to list the files to remove at the end of tests groups.
9944 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
9945 (AT_data_files, at_data_files): Remove.
9946 (AT_CLEANUP, AT_DATA): Simplify.
9947 (AT_INIT): Adjust.
9948 Remove the group dir if !debug && !failed.
9949 * tests/atspecific.m4: Adjust.
9951 2001-11-13 Akim Demaille <akim@epita.fr>
9953 Start a new layout for Autotest: `testsuite' creates
9954 `testsuite.dir' in which the at-check-line etc. files are to be
9955 found, and `testsuite.dir/003' where the test group 3 is run.
9957 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
9958 at_check_line_file, at_format, at_test_normalized, at_group_dir
9959 are new variables.
9960 Create the directories.
9961 Use absolute paths for at- files.
9962 (AT_CHECK): Adjust.
9964 2001-11-11 Michael Matz <matz@kde.org>
9966 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
9967 (m4_car2): New.
9968 (m4_car): Properly quote arguments.
9970 2001-11-13 Akim Demaille <akim@epita.fr>
9972 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
9973 with stricter rules on LIBOBJS.
9975 2001-11-12 Paul Eggert <eggert@twinsun.com>
9977 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
9978 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
9979 __PROTOTYPES too.
9981 2001-11-12 Akim Demaille <akim@epita.fr>
9983 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
9985 2001-11-12 Akim Demaille <akim@epita.fr>
9987 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9988 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
9989 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9990 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
9991 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
9992 specify to what the macro should be defined (typically to 1).
9994 2001-11-12 Akim Demaille <akim@epita.fr>
9996 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
9997 From Jim Meyering.
9999 2001-11-12 Akim Demaille <akim@epita.fr>
10001 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10002 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10003 definition used by Automake where LEX is +/- "${missing} lex" and
10004 `missing' itself contains variables.
10006 2001-11-12 Akim Demaille <akim@epita.fr>
10008 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10009 Now that M4sh pushes BODY, the comments were output at the end of
10010 the test suites.
10012 2001-11-08 Akim Demaille <akim@epita.fr>
10014 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10015 that we can trace macros from aclocal.m4.
10016 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10017 obsoleted, and redirect to the former anyway.
10018 Reported by Ralf Corsepius.
10020 2001-11-08 Akim Demaille <akim@epita.fr>
10022 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10023 processed only if present.
10024 * tests/torture.at (Configuring subdirectories): Use autoreconf
10025 instead of successive calls to autoconf.
10026 Add a nonexistent subdirectory to exercise the patch above.
10027 Reported by Ralf Corsepius.
10029 2001-11-08 Kevin Ryde <user42@zip.com.au>
10031 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10032 doesn't accept .S files.
10034 2001-11-07 Akim Demaille <akim@epita.fr>
10036 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
10037 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
10038 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10039 * bin/autom4te.in (warn_forbidden): New.
10040 (handle_output): Use it.
10041 Read m4_pattern_forbid with messages.
10043 2001-11-05 Akim Demaille <akim@epita.fr>
10045 * bin/autom4te.in (--normalize): Remove.
10046 * lib/autom4te.in: Adjust.
10048 2001-11-05 Akim Demaille <akim@epita.fr>
10050 * tests/Makefile.am (testsuite): Rename this target as...
10051 ($(TESTSUITE)): this.
10052 From Nicolas Joly.
10054 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10056 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10057 the --prefix option, also remove it's argument.
10059 2001-11-05 Akim Demaille <akim@epita.fr>
10061 * doc/autoconf.texi (testsuite Invocation): Update.
10062 (Writing testsuite.at): Update.
10064 2001-11-03 Akim Demaille <akim@epita.fr>
10066 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10068 2001-11-03 Akim Demaille <akim@epita.fr>
10070 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10071 (&file_name_is_absolute): New, wrappers around routines from
10072 File::Spec.
10073 Use and export them.
10074 (&find_configure_ac): Optionally take a directory where to look at.
10075 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10076 the arguments.
10077 Default @ARGV to `.', not find_configure_ac.
10078 (&autoreconf): Argument is a directory.
10079 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10080 * doc/autoconf.texi (autoreconf Invocation): Update.
10082 2001-11-03 Akim Demaille <akim@epita.fr>
10084 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10085 (@export_forward_subs): New.
10086 Add basename, dirname, and fileparse.
10087 (@EXPORT): Adjust.
10088 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10089 Don't look for aclocal flags if we already know aclocal is not
10090 used.
10091 Move aclocal.m4t only if it exists.
10092 Reported by Ezra Peisach.
10094 2001-11-03 Akim Demaille <akim@epita.fr>
10096 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10097 passed on command line, defaulting to ./configure.ac if present.
10098 (&maybe_autoreconf, File::Find): Remove, unused.
10099 (&autoreconf): If autoconf is not used, don't try to trace.
10101 2001-11-02 Akim Demaille <akim@epita.fr>
10103 * configure.ac: Bump to 2.52g.
10105 2001-11-02 Akim Demaille <akim@epita.fr>
10107 Version 2.52f.
10109 2001-11-02 Akim Demaille <akim@epita.fr>
10111 * config/config.guess, config/config.sub, doc/standards.texi:
10112 * config/lispdir.m4: Update from masters.
10113 * configure.ac: Bump to 2.52f.
10115 2001-11-02 Akim Demaille <akim@epita.fr>
10117 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10118 Don't run aclocal when aclocal.m4 is not from aclocal.
10119 From Ezra Peisach.
10120 Don't run libtoolize and gettextize if --install is not given.
10122 2001-11-01 Paul Eggert <eggert@twinsun.com>
10124 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10125 be invoked before _AS_LINENO_PREPARE.
10126 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10127 than character ranges.
10129 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10130 invoking AS_BASENAME. Set the locale variables to 'C' if
10131 possible, as POSIX requires this to get the traditional
10132 behavior.
10133 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10135 2001-10-31 Paul Eggert <eggert@twinsun.com>
10137 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10138 with {}, as that triggers a bug in Bash 2.05.
10140 (_AS_LINENO_PREPARE): Use Sed rather than
10141 Awk. Fix the sed prepass to work even if there are multiple
10142 instances of $LINENO on the same line. Do not substitute for
10143 other variables like $LINENOT. Do not check file dates; such a
10144 check is unreliable on sufficiently fast machines, and removing
10145 the check makes the code simpler and more reliable. Check for
10146 output and chmod failures.
10148 * doc/autoconf.texi (Special Shell Variables): Document
10149 the above.
10151 2001-10-31 Akim Demaille <akim@epita.fr>
10153 * tests/Makefile.am (atconfig): Remove this target, Automake
10154 handles it now.
10156 2001-10-31 Akim Demaille <akim@epita.fr>
10158 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10159 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10160 provided, while it is optional.
10161 * configure.ac: Adjust.
10163 2001-10-26 Paul Eggert <eggert@twinsun.com>
10165 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10166 lib/Autom4te/Struct.pm:
10167 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10168 with 5.005_02.
10170 * doc/autoconf.texi (Special Shell Variables): Document some
10171 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10173 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10174 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10175 eval $LINENO is not portable in practice.
10177 2001-10-24 Akim Demaille <akim@epita.fr>
10179 * lib/Autom4te/General.pm (backname): New.
10181 2001-10-24 Akim Demaille <akim@epita.fr>
10183 * m4/: Remove, merged into...
10184 * config/: here.
10186 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10188 * doc/autoconf.texi (Shellology): Mention the problems with bash
10189 2.05's use of ANSI quoting in its `set' builtin.
10191 2001-10-22 Paul Eggert <eggert@twinsun.com>
10193 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10194 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10195 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10196 POSIX decided to standardize on the int flavor of strerror_r.
10197 Always do char* test, as there's no reason not to.
10198 Assign to a char* var, to catch strerror_r that returns int*.
10200 * doc/autoconf.texi (Particular Functions):
10201 Document the above changes. Also, document the fact that
10202 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10204 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10206 2001-10-20 Akim Demaille <akim@epita.fr>
10208 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
10209 the executable was missing from the log.
10211 2001-10-20 Akim Demaille <akim@epita.fr>
10213 * lib/Autom4te/General.pm (&update_file): If destination is
10214 unchanged, remove the source.
10215 (&up_to_date_p): Don't be verbose, be debug.
10216 * bin/autoreconf.in: No longer support --m4dir.
10217 (&autoreconf): Display the full path of the configure.ac we are
10218 studying.
10219 Trace it only once.
10220 Be sure to honor --force with gettextize.
10221 Always run aclocal.
10222 * doc/autoconf.texi: Adjust.
10224 2001-10-20 Akim Demaille <akim@epita.fr>

10508 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

10674 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
10675 Suggested by Jim Meyering.
10677 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10679 * lib/autoconf/programs.m4: Use extensions listed in
10680 $ac_executable_extensions when looking for programs.
10682 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10684 * lib/autoconf/general.m4: Fix a small Englisho.
10685 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
10686 setting up ac_dir_suffix and ac_top_builddir.
10687 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
10689 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10691 * doc/autoconf.texi (File System Conventions): Clarify the use of
10692 PATH_SEPARATOR.
10693 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
10694 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
10695 be used instead of ':'.
10696 * lib/autotest/general.m4: Replace occurrences of ':' in
10697 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
10699 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10701 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
10702 arguments. Fixed a typo.
10704 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10706 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
10707 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
10709 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10711 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
10712 * bin/autoupdate.in: Ditto.
10713 * bin/autoheader.in: Reworded a few comments.
10714 * bin/autoconf.in: Reworded help text for a few options.
10715 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10716 * bin/autoscan.in, bin/autoupdate.in: Ditto.
10718 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10720 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
10721 already have $file). Set output files to binary mode (helps avoid
10722 CR issues on DOSish systems).
10724 2001-09-19 Akim Demaille <akim@epita.fr>
10726 * lib/autotest/general.m4: Englishoes.
10727 From Tim Van Holder and Alexey Mahotkin.
10729 2001-09-18 Paul Eggert <eggert@twinsun.com>
10731 * doc/autoconf.texi (Common Shell Constructs): New node,
10732 documenting AS_DIRNAME.
10733 (Limitations of Usual Tools): Refer to it when discussing dirname.
10734 Also, update discussion of POSIX standard to reflect latest draft.
10736 * lib/autoconf/c.m4:
10737 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
10739 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10740 Do not pass a first argument with leading '-'
10741 to expr, by parenthesizing initial integers that might be negative.
10743 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
10744 now merely checks whether it is an error to pass an argument
10745 to getpgrp.
10747 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
10748 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
10749 whether it is a (compile-time) error to pass an argument to
10750 getpgrp. This simpler test supports the revised documentation,
10751 and is all that AC_FUNC_GETPGRP's users really need.
10753 2001-09-18 Akim Demaille <akim@epita.fr>
10755 * doc/autoconf.texi (Limitations of Make) <$<>: New.
10757 2001-09-18 Akim Demaille <akim@epita.fr>
10759 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
10760 `{}'.
10761 * lib/autotest/general.m4 (AT_INIT): Adjust.
10763 2001-09-18 Paul Wagland <paul@wagland.net>
10765 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
10766 correctly.
10767 Add test for AS_BASENAME.
10768 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
10769 added test. It now correctly handles /1/2/3/, returning '3' not ''.
10770 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
10771 * tests/base.at: Fixed the expected responses. The old ones were
10772 one line out...
10773 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
10774 the documentation claims it should (and how it behaved in 2.13).
10776 2001-09-18 Akim Demaille <akim@epita.fr>
10778 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
10779 the AC_CONFIG_COMMANDS invocation.
10780 This also solves the name clash problems.
10781 Don't set the package's ID.
10782 * lib/m4sugar/Makefile.am (version.m4): Revamp.
10783 No longer to be shipped.
10784 (version.in): Remove.
10785 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
10786 * lib/autoconf/status.m4: Adjust.
10787 Use `m4_PACKAGE_STRING'.
10788 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
10789 the only optional argument is the name of the test suite.
10790 Expect `package.m4' to define the package signature.
10791 * lib/autom4te.in (Autotest): Add `package.m4?'.
10792 * tests/Makefile.am (package.m4): New.
10793 * tests/suite.at: ifnames is a victim.
10795 2001-09-18 Akim Demaille <akim@epita.fr>
10797 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
10798 AC_LIBSOURCE, AC_CONFIG_FILES.
10799 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
10800 program version string doesn't match the package's.
10801 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
10802 after `(cached)'.
10804 2001-09-17 Paul Eggert <eggert@twinsun.com>
10806 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10807 Allow expression to return any value that can fit into unsigned long
10808 (not int, as before). Check for output errors.
10810 2001-09-17 Bruno Haible <haible@ilog.fr>
10812 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10813 Always include <stdio.h> and <stdlib.h>. Evaluate
10814 the expression in an extra function before these includes. Call
10815 fprintf "%d" only after ensuring the argument is of type 'int'.
10816 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
10818 2001-09-17 Paul Eggert <eggert@twinsun.com>
10820 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
10821 or CFLAGS=-O5. In that case, the linker has a relaxed view of
10822 fatal errors, and AC_CHECK_LIB causes it to include libraries even
10823 when they don't exist.
10825 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
10826 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
10827 need it.
10829 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
10830 version with the version used by fileutils 4.1, except use
10831 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
10832 we don't need it.
10834 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
10836 2001-09-13 Akim Demaille <akim@epita.fr>
10838 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
10839 _first_.
10840 Reported by Gerrit P. Haase.
10842 2001-09-13 Akim Demaille <akim@epita.fr>
10844 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
10845 m4_defn'ing is valid.

10851 Use it.

10860 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
10861 Likewise.

10864 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
10865 AT_tests_all for consistency.
10866 Set at_victims.
10867 (AT_VICTIMS): Similar to AT_KEYWORDS.
10868 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
10870 2001-09-13 Akim Demaille <akim@epita.fr>
10872 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
10874 2001-09-13 Akim Demaille <akim@epita.fr>
10876 * lib/autotest/general.m4 (AT_INIT): Create and remove
10877 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
10878 test suites can cohabit.
10880 2001-09-13 Akim Demaille <akim@epita.fr>
10882 * tests/mktests.sh: Don't output banners for empty test files.
10884 2001-09-13 Akim Demaille <akim@epita.fr>
10886 Test suites can be run independently of configure.

10932 2001-09-10 Akim Demaille <akim@epita.fr>
10934 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

10967 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
10968 in addition, it introduces useless differences in logs.

10988 2001-09-05 Akim Demaille <akim@epita.fr>

10991 the maintainer is dumb enough to do that...
10993 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
10994 excellence in M4 quotation: consider `__file__' is active.

11027 New, extracted from main.
11028 Use IO::File wherever possible.
11029 (input.m4): Be constant, use -I instead of hard coding $tmp.

11031 Don't invoke `_au_disable', since ac was not loaded, but just
11032 `unm4.m4'.
11034 2001-08-31 Akim Demaille <akim@epita.fr>
11036 Version 2.52d.

11059 2001-08-31 Akim Demaille <akim@epita.fr>
11061 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11062 (testsuite Scripts): There is no such thing as `atconfig.in'.

11065 2001-08-31 Akim Demaille <akim@epita.fr>
11067 * lib/Autom4te/General.pm (&find_file): Browse the includes in the

11078 autom4te_perllibdir.
11080 2001-08-31 Akim Demaille <akim@epita.fr>
11082 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11083 debug scripts, in particular passing explicitly listed tests to
11084 run is stupid.
11086 2001-08-31 Akim Demaille <akim@epita.fr>
11088 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11089 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11090 Use directly autom4te, not autoconf.

11115 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
11116 (autoheader): Pass --force since the test suite goes too fast for
11117 the time stamps.

11130 * lib/Autom4te/General.pm (&find_file, &update_file): New.
11131 * bin/autoupdate.in, bin/autoheader.in: Adjust.
11132 Drop AC_MACRODIR dead for real.
11133 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11134 `autoheader: `config.hin' is created'.
11135 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11137 2001-08-31 Akim Demaille <akim@epita.fr>
11139 * bin/autoheader.in: Rewrite in Perl.
11140 * tests/autoheader: Adjust.
11142 2001-08-31 Akim Demaille <akim@epita.fr>
11144 * bin/autoconf.in (--include, -I): New option.
11145 Map --localdir, --autoconf-dir onto it.
11146 Forward autom4te's options instead of interpreting them.
11147 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11148 There is no such envvar since the inception of autom4te.cfg.
11149 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11150 * bin/autoupdate.in: Adjust, and perform more control.
11151 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
11152 * tests/autoconf: Dittowise.
11154 2001-08-31 Akim Demaille <akim@epita.fr>
11156 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
11157 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11158 optionally `FILE'.
11159 Use -e, not -f, since /dev/null for instance is OK.
11160 (&parse_args): Adjust.
11161 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11163 2001-08-31 Akim Demaille <akim@epita.fr>
11165 * configure.ac: Also find tested executables in bin.
11166 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11167 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11168 installed peer executables, only PATH is allowed to resolve it.
11169 Pass `autoconf_dir' via options, not via invisible envvars.
11170 * lib/Autom4te/General.pm (&find_peer): Remove.
11171 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11172 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11173 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11174 find the executables for it.
11175 * tests/Makefile.am: Major cleanup. Too lazy to document...
11176 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11177 We only need PERL.
11178 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11179 indeed related to running the test suite, while passing
11180 --autoconf-dir and others is related to running non installed
11181 Autoconf executables. So don't do that, leave it to...
11182 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11183 * tests/autoscan: New.
11184 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11185 refer to library files: rely on --language.
11187 2001-08-29 Akim Demaille <akim@epita.fr>
11189 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
11190 s/--set/--language/.
11192 2001-08-29 Akim Demaille <akim@epita.fr>
11194 * doc/autoconf.texi: Strip the @nodes.
11195 Suggested by Paul Eggert.
11196 (Initializing configure): Typo.
11198 2001-08-29 Akim Demaille <akim@epita.fr>
11200 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11201 Suggested by Paul Eggert.
11203 2001-08-29 Akim Demaille <akim@epita.fr>
11205 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11206 download in a tmp dir.
11208 2001-08-29 Akim Demaille <akim@epita.fr>
11210 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
11211 case insensitive OSes out there :(
11212 From Tim Van Holder.
11214 2001-08-29 Akim Demaille <akim@epita.fr>
11216 * lib/autom4te.in: New.
11217 * lib/Makefile.am (edit, autom4te.cfg): New.
11218 * bin/autom4te.in (BEGIN): Simplify.
11219 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
11220 (&load_configuration): New. Use it.
11221 (&parse_args): Support --mode, --set, and --melt.
11222 * bin/autoconf.in: Simplify and adjust.
11223 * tests/Makefile.am (AUTOMAKE): Use --set.
11224 * tests/atlocal.in: Adjust.
11225 * BUGS: distcheck and check are weak.
11227 2001-08-29 Akim Demaille <akim@epita.fr>
11229 * lib/autotest/general.m4: Use
11230 foo=`(command) 2>/dev/null`
11231 not
11232 foo=`command` 2>/dev/null
11233 (at-devnull): Rename as...
11234 (AT-devnull): this.
11235 (--clean): Remove AT-* files too.
11236 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
11237 Reported by Nicolas Joly.
11239 2001-08-28 Akim Demaille <akim@epita.fr>
11241 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
11242 quotes inside single quotes.
11243 Reported by Nicolas Joly.
11245 2001-08-28 Kevin Ryde <user42@zip.com.au>
11247 * doc/autoconf.texi (Function Portability): Mention C right shifts.
11249 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
11251 * lib/autotest/general.m4: Reword some messages.
11252 (AT_INIT): Check for the `times' builtin before using it.
11253 Support test ranges as arguments to the testsuite.
11254 Have -e imply -d as the help text suggested.
11256 2001-08-27 Akim Demaille <akim@epita.fr>
11258 * Makefile.maint: Formatting changes.
11259 (do-po-update, po-update, cvs-update, update): New targets.

11262 2001-08-27 Akim Demaille <akim@epita.fr>
11264 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

11271 * lib/autotest/general.m4 (AT_INIT): Log the command line.
11272 Support `VAR=VAL' as arguments.
11273 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
11274 may be set via the command line.
11276 2001-08-27 Akim Demaille <akim@epita.fr>
11278 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
11279 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
11280 first the build dirs, then the src dirs.

11283 2001-08-27 Akim Demaille <akim@epita.fr>
11285 * lib/autotest/general.m4 (AT_INIT): Output the definition of
11286 at_data_files earlier.
11287 (--clean, -c): New option.
11288 * tests/Makefile.am: Use this option.
11290 2001-08-27 Akim Demaille <akim@epita.fr>
11292 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
11293 `ac_top_builddir' to mimic Automake's vocabulary, which much more
11294 readable.
11295 Adjust callers.
11296 * doc/autoconf.texi (Configuration Actions): Document the vars
11297 available in commands.
11298 Emphasize the risks of collisions in init-cmds.

11302 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
11303 (Initializing configure): this new node.
11305 2001-08-27 Akim Demaille <akim@epita.fr>

11328 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
11329 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
11330 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
11331 -> ac_dir).
11332 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
11333 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
11335 2001-08-27 Akim Demaille <akim@epita.fr>

11360 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
11361 (AMTAR): Help automake define it.
11362 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
11363 needed, 1.5 can have a macro and a target with the same name.
11364 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
11365 * m4/strip.m4: New.

11378 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
11379 Adjust callers.
11380 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
11381 the name of the directory they're in, instead of the filename,
11382 since version.m4 is now in m4sugar, but m4_acversion must not be
11383 classified as an Autoconf macro.
11384 ($input_m4): Don't qualify the path to m4sugar.
11385 Rather, pass autoconf_dir to m4.
11386 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
11387 * tests/suite.at: Require 2.52c.
11389 2001-08-27 Akim Demaille <akim@epita.fr>

11401 of config.log on traps.
11402 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
11403 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
11404 for config.status'.
11405 Open the log as soon as possible.
11406 Use the same log introduction as configure's.
11408 2001-08-22 Paul Eggert <eggert@twinsun.com>
11410 * doc/autoconf.texi (Indices): New node.
11411 Move indices out of the top level menu and into this submenu.
11413 2001-08-22 Akim Demaille <akim@epita.fr>
11415 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11416 AC_TRY_COMMAND.
11417 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.
11419 2001-08-22 Akim Demaille <akim@epita.fr>
11421 * lib/autoconf/general.m4 (AC_SHELL_PATH_WALK, AC_CHECK_PROG)

11426 (AC_PROG_RANLIB, AC_PROG_YACC, AC_PROG_LEX, _AC_DECL_YYTEXT)
11427 (AC_PROG_INSTALL, AC_PROG_LN_S, AC_RSH): Move to...
11428 * lib/autoconf/programs.m4: here.
11429 (_AC_DECL_YYTEXT): Rename as...
11430 (_AC_PROG_LEX_YYTEXT_DECL): this.

11458 * configure.ac (AT_CONFIG): Fix the path.
11459 * m4/atconfig.m4 (AT_CONFIG): Don't use EOF but ATEOF so that 2.52
11460 can be used.

11464 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
11465 program with AC_LANG_PROGRAM before feeding it to
11466 AC_COMPILE_IFELSE. Cleanup grep usage.
11468 2001-08-20 Akim Demaille <akim@epita.fr>
11470 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
11471 * NEWS, README, README-alpha, TODO, tests/README: This package is
11472 `Autoconf', not `autoconf' (the executable).
11474 2001-08-20 Akim Demaille <akim@epita.fr>
11476 Info readers seem to need `Index' in the index node title :(
11478 * doc/autoconf.texi: Reverse the 2001-08-15 change which
11479 simplified index node names.
11481 2001-08-20 Akim Demaille <akim@epita.fr>
11483 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
11484 arguments are not literals.
11485 * doc/autoconf.texi (Input) <AC_INIT>: Arguments must be literals.
11486 Specify the output variables, and macros defined.
11488 2001-08-20 Akim Demaille <akim@epita.fr>
11490 * doc/autoconf.texi (Examining Declarations) <AC_TRY_CPP>:
11491 (Examining Syntax) <AC_TRY_COMPILE>
11492 (Examining Libraries) <AC_TRY_LINK>
11493 (Test Programs) <AC_TRY_RUN>: These macros double quote some of
11494 their arguments.
11495 Reported by Werner Lemberg.
11497 2001-08-20 Akim Demaille <akim@epita.fr>

11514 * lib/autoconf/general.m4 (_AC_OUTPUT_COMMANDS): Say what you do.
11515 * m4/atconfig.m4 (AT_CONFIG): $1 is now the directory where the
11516 test suite lives.
11517 Create `atconfig' automagically.

11523 2001-08-20 Akim Demaille <akim@epita.fr>
11525 Huh!?!?! There are still some user EOF tags used, which prevents
11526 their use in AC_CONFIG_COMMANDS for instance...
11528 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
11529 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
11530 `_CSEOF', or `_ATEOF', as appropriate.
11531 * lib/m4sugar/Makefile.am, lib/autoconf/Makefile.am,
11532 * lib/autotest/Makefile.am (check-local): Enforce this constraint.

11542 Autotest invokes M4sh's initialization.

11592 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

11610 * doc/autoconf.texi: Work around Texinfo buglets.

11665 (cvs-dist): depends upon it.
11667 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
11669 * tests/Makefile.am: Use a clean-local rule to remove
11670 autom4te.cache (it's a directory, not a file.
11671 * Makefile.am: Ditto (but maintainer-clean-local).
11673 2001-08-15 Akim Demaille <akim@epita.fr>
11675 * bin/autom4te.in (@m4_warning): New.
11676 (&handle_m4): Use it.
11677 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
11678 warnings are issued at each run.
11679 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
11680 is in the src tree.
11682 2001-08-15 Akim Demaille <akim@epita.fr>

11685 don't waste time running `autoupdate --version' works.
11686 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
11688 2001-08-13 Akim Demaille <akim@epita.fr>

11747 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11749 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
11750 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
11751 * doc/autoconf.texi (C Compiler Characteristics): Update
11752 documentation for AC_C_BIGENDIAN.
11754 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11756 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
11757 magic values from an object file when cross-compiling.
11758 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
11760 2001-08-10 Akim Demaille <akim@epita.fr>
11762 * bin/autom4te.in (&handle_output): Don't use `grep' with side
11763 effects.
11764 Suggested by Russ Allbery.
11766 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
11768 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
11769 current $prefix to the sub-configures.
11771 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
11773 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
11774 extension (needed on BeOS). Reported by Guido van Rossum.
11776 2001-08-09 Akim Demaille <akim@epita.fr>
11778 * bin/autom4te.in ($icache): Load it only if older than autom4te.
11780 2001-08-07 Akim Demaille <akim@epita.fr>
11782 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
11783 removed.
11784 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
11785 No need to remove the files before and after the each test, before
11786 each test and at the end of the suite is enough.
11787 Display only the children `times', not the shell's.
11788 If the test failed or was skipped, at-times is not available.
11790 2001-08-07 Akim Demaille <akim@epita.fr>
11792 Always produce testsuite.log, including when there are no
11793 failures. This helps getting information on skipped tests, and
11794 duration of the tests. Err, implement the latter btw.
11796 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
11797 Dump information on the first run of each test.
11798 (AT_CLEANUP): Create `at-times' containing the duration of the
11799 test group.
11801 2001-08-07 Akim Demaille <akim@epita.fr>
11803 The use of `dumpstat' revealed that `len' was used although it
11804 should not. m4_text_wrap was using it, but in the Autoconf world
11805 where it is legal. Hence (i) test M4sh in its own world, not
11806 Autoconf's, and (ii), ahem, fix the bug :)
11808 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
11809 does not like `' instead of [].
11810 (AT_INIT): Forbid `^_?AT_'.
11811 And don't output such tokens.
11812 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
11813 `script.as', and `autom4te.cache'.
11814 Remove `empty' and `macro' which are no longer used.
11815 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
11816 * tests/m4sugar.at: Use it.
11817 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
11819 2001-08-07 Akim Demaille <akim@epita.fr>
11821 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
11823 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
11825 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
11827 2001-08-04 Akim Demaille <akim@epita.fr>
11829 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
11830 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
11831 AC_TRY_LINK.
11832 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
11833 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
11834 (AC_F77_MAIN): Likewise.
11836 2001-08-04 Akim Demaille <akim@epita.fr>
11838 Don't rely on M4sugar outputting the patterns in files, since we
11839 might process the output _without_ running m4, hence without these
11840 files.
11842 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
11843 * bin/autom4te.in (@Request::includes): Remove, unused.
11844 (@Request::source): Rename as...
11845 (@Request::input): this.
11846 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
11847 (&handle_output): Fetch the patterns from the traces.
11848 `$forbidden' and `$allowed' are constant: use m//o.
11849 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
11850 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
11852 2001-08-04 Akim Demaille <akim@epita.fr>
11854 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
11855 autoconf', i.e., in addition to caching traces, cache the output.
11857 * bin/autom4te.in (Request::cache): Rename as...
11858 (Request::id): this.
11859 ($cache, $icache, $tcache, $ocache): New.
11860 (&handle_m4): Save M4 output in the cache instead of $tmp.
11861 (&handle_output): Adjust.
11862 (&up_to_date_p): Check that the output cache is up to date too.
11863 (top level): Run `&handle_m4' iff force or the cache is invalid.
11864 Run `&handle_output' if the output cache is more recent.
11866 2001-08-04 Akim Demaille <akim@epita.fr>
11868 * bin/autom4te.in ($force): New.
11869 (&parse_args, &print_usage): -f, --force is a new option.
11870 (&handle_output): CPP directives might have spaces after `#'.
11871 (&parse_args): The first file only can be frozen.
11873 2001-08-04 Akim Demaille <akim@epita.fr>
11875 Don't let autom4te compute the `include' traces several times:
11876 first check that the trace cache file is up to date, and then
11877 compare its timestamp with that of the output.
11879 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
11880 the preamble. Don't require 5.005 as Autom4te::General does it,
11881 and better yet (use `use', not `require'!).
11882 * lib/Autom4te/Struct.pm: Rename the last occurrences of
11883 Class::Struct as Autom4te::Struct.
11884 * lib/Autom4te/General.pm (File::stat): Use it.
11885 (&mtime): New, export it.
11886 * bin/autom4te.in: Use it.
11887 Declare `$req' is invalid if it is outdated.
11888 Don't declare it valid before saving it if something went wrong.
11890 2001-08-04 Akim Demaille <akim@epita.fr>
11892 Autom4te shall not encode Autoconf data, and preselecting traces
11893 must be proposed to the users.
11895 * bin/autom4te.in (@required_trace): Remove.
11896 (@preselect): New.
11897 (&parse_args, &print_usage): -p, --preselect is a new option.
11898 (&up_to_date_p): Adjust.
11899 * bin/autoconf.in: Preselect some Autoconf macros.
11901 2001-08-04 Akim Demaille <akim@epita.fr>
11903 * tests/tools.at (autoconf --trace: user macros): Check traces on
11904 macros invoked without arguments, and macros invoked with multiple
11905 lines arguments.
11907 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
11909 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
11910 arguments.
11912 2001-08-03 Akim Demaille <akim@epita.fr>
11914 * bin/autoconf.in ($@): Work around the usual sh bug.
11915 From Nicolas Joly.
11917 2001-08-03 Akim Demaille <akim@epita.fr>
11919 Clean up the handling of the M4 builtins tracing exception.
11921 * bin/autom4te.in (Request::request): Don't complete M4 builtins
11922 trace requests.

11924 (@m4_builtin): this.
11925 (%m4_builtin_alternate_name): New.
11926 (&parse_args): Complete the trace requests with alternate names.
11927 (&handle_traces): Hence no longer do it here.
11928 (&trace_requests): Remove, unused.
11930 2001-08-03 Akim Demaille <akim@epita.fr>
11932 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
11933 m4_if, and m4_wrap.
11935 2001-08-03 Akim Demaille <akim@epita.fr>
11937 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
11938 (m4_divert_pop): Dump the whole diversion stack when a diversion
11939 mismatch happens.
11940 * bin/autom4te.in (&handle_output): Remember of the first
11941 occurrence of a possibly undefined macro, not the last.
11942 Complain about the possibly undefined macros in the same order as
11943 the appear in the output.
11944 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
11945 * tests/tools.at (autoconf: forbidden tokens, basic)
11946 (autoconf: forbidden tokens, exceptions): No longer sort
11947 autoconf's stderr, as it is now deterministic.
11948 Check that `dnl' is caught.
11950 2001-08-01 Akim Demaille <akim@epita.fr>
11952 * configure.ac: Bump to 2.52c.

11967 `die'.
11968 (&END): New.
11969 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
11970 `END', as `Autom4te::General::END' will be triggered.
11971 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
11972 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

12364 compiler, not the preprocessor.
12365 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): No longer use

12371 2001-07-03 Akim Demaille <akim@epita.fr>

12400 * aclang.m4 (AC_F77_DUMMY_MAIN): New macro to detect whether a
12401 dummy alternate main is required even if the user provides her own
12402 'main'.
12403 (AC_F77_MAIN): New macro to detect whether it is possible to
12404 provide an alternate 'main' function name, using the 'main' from
12405 the Fortran libraries.
12406 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
12407 cross-language link tests can be performed successfully.
12408 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
12409 after $LIBS, for consistency; this should be the general rule since
12410 the user may want to link to Fortran libraries that require $FLIBS.
12411 * doc/autoconf.texi: Document AC_F77_DUMMY_MAIN and AC_F77_MAIN.
12413 2001-06-29 Pavel Roskin <proski@gnu.org>
12415 * atgeneral.m4 (AT_CHECK): Add a newline to the end of
12416 at-stdout and at-stderr instead of removing the newline
12417 from the echo output, which is not guaranteed to work.
12419 2001-06-28 Jens Petersen <petersen@redhat.com>
12421 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to

12453 explicit macros is mapped to the default macro.
12454 (&print_unique): Remove, inlined in...
12455 (&output_kind): here.
12456 (File::Basename): Use it.

12465 Suggested by Mo DeJong.
12467 2001-06-24 Akim Demaille <akim@epita.fr>

12478 2001-06-23 Akim Demaille <akim@epita.fr>
12480 * tests/torture.at (AC_ARG_VAR): Make it a single test instead of
12481 three as failures are unlikely, and speed matters.
