Problem reported by Mark Krenz <https://bugs.gnu.org/48085>.
* lib/mktime.c (__mktime_internal): Be more generous about
accepting arguments with the wrong value of tm_isdst, by falling
back to a one-hour DST difference if we find no nearby DST that is
unusual. This fixes a problem where "1986-04-28 00:00 EDT" was
rejected when TZ="America/Indianapolis" because the nearest DST
timestamp occurred in 1970, a temporal distance too great for the
old heuristic. This also also narrows the search a bit, which
is a minor performance win.
* m4/mktime.m4 (gl_FUNC_MKTIME_WORKS):
Check for putenv failures and for Bug#48085.
* tests/test-parse-datetime.c (main):
Test for setenv failures and for Bug#48085.

Reported by Reuben Thomas <rrt@sc3d.org> in
<https://lists.gnu.org/archive/html/bug-gnulib/2021-04/msg00104.html>.
This is done by defining the Gnulib module indicator variables per
gnulib-tool invocation. So that a generated .h file is no longer
influenced by the set of modules used in other gnulib-tool invocations.
* gnulib-tool (func_compute_include_guard_prefix): Set
module_indicator_prefix.
(func_emit_lib_Makefile_am, func_emit_tests_Makefile_am): Use it to
modify $(GNULIB_*) variable references in the Automake snippets.
(func_emit_initmacro_start): Push macro definitions for GL_MACRO_PREFIX
and GL_MODULE_INDICATOR_PREFIX.
(func_emit_initmacro_end): Pop these macro definitions.
* pygnulib/GLConfig.py (GLConfig.getIncludeGuardPrefix): New method.
* pygnulib/GLEmiter.py (GLEmiter.initmacro_start): Push macro
definitions for GL_MACRO_PREFIX and GL_MODULE_INDICATOR_PREFIX.
(GLEmiter.initmacro_end): Pop these macro definitions.
(GLEmiter.lib_Makefile_am, GLEmiter.tests_Makefile_am): Use the module
indicator prefix to modify $(GNULIB_*) variable references in the
Automake snippets.
* m4/gnulib-common.m4 (gl_MODULE_INDICATOR_INIT_VARIABLE,
gl_MODULE_INDICATOR_SET_VARIABLE): Use the value of
GL_MODULE_INDICATOR_PREFIX.
* m4/arpa_inet_h.m4: Use new idiom for header files that contain
references to Gnulib module indicator variables:
- Define the main macro through AC_DEFUN_ONCE.
- Define a macro gl_*_H_REQUIRE_DEFAULTS that initializes the Gnulib
module indicator variables (each prefixed with
GL_MODULE_INDICATOR_PREFIX).
- Invoke this macro in the gl_*_MODULE_INDICATOR macro.

On mingw (at least, when cross-compiling with Fedora 18's
mingw32-headers-2.0.999-0.15.trunk.20121110.fc18.noarch build),
compilation of test-regex fails:
test-regex.c: In function 'main':
test-regex.c:42:11: error: 'SIGALRM' undeclared (first use in this function)
test-regex.c:42:11: note: each undeclared identifier is reported only
once for each function it appears in
test-regex.c:43:3: warning: implicit declaration of function 'alarm'
It turns out that recent mingw64 added an export of alarm() and
SIGALRM, but guarded their declarations behind __USE_MINGW_ALARM
(default off, and with alarm() only in the non-standard <io.h>);
so the m4 tests were setting HAVE_ALARM to 1 based on link success
but then failing to compile.
* doc/posix-functions/alarm.texi (alarm): Document that alarm
exists but still doesn't work in newer mingw.
* m4/frexp.m4 (gl_FUNC_FREXP_WORKS): Check for alarm declaration,
not existence. Ensure SIGALRM is not trapped.

99% of this change was performed by running the following commands:
git ls-files | grep '\.m4$' | xargs perl -pi \
-e 's/(AC_\w+\()([^[()]+?)([,)])/$1\[$2]$3/g;' \
-e 's/(AC_\w+\((?:\[[^,]+?\], ){1})([^,[()]+?)([,)])/$1\[$2]$3/g;' \

perl -pi -e 's/\[\.\.\.\]/.../' m4/onceonly.m4
The remainder were to add Copyright dates, increment serial numbers,
undo some changes in comments, exclude m4/intl.m4, and add quotes
around the "1" in ",1" where the unusual spacing prohibited the
above regexps from doing the job. For more details, see

module sys_time.
* lib/gethrxtime.c: Include <sys/time.h>, since we can no longer
assume timespec.h defines struct timeval.
* lib/settime.c: Likewise.
* lib/utimens.c: Likewise.
* lib/gettime.c (gettime): Remove test against HAVE_GETTIMEOFDAY,
since we now assume the gettimeofday module.
* lib/tempname.c (__gen_tempname): Likewise.
* lib/gettimeofday.h: Remove.
* lib/gettimeofday.c: Include <sys/time.h> instead of "gettimeofday.h".
Don't include <sys/types.h> and <stdlib.h>; shouldn't be needed.
Include <time.h>, for 'time()'.
(localtime_buffer_addr): Also use this workaround if
TZSET_CLOBBERS_LOCALTIME. Set to a dummy static variable by default,
to simplify the uses. All uses changed.
(localtime, gmtime, tzset, gettimeofday): Reformat slightly so
that #undef is inside {}, and 'const' follows type name consistently.
(tzset): Define replacement only if TZSET_CLOBBERS_LOCALTIME.
(gettimeofday): Do not use the maximum possible value for
tv->tv_usec, since that might break usages other than ls.c.
Instead, we'll leave ls.c alone. This undoes today's patch
by Bruno. Add a compile-time warning for 1s-clock resolution;
we've never observed the problem but might as well keep the
canary.
* lib/nanosleep.c: Include timespec.h first, for interface check.
* lib/nanosleep.c: Include <sys/time.h> unconditionally, since we
now assume the sys_time module.
* lib/tempname.c: Likewise.
* lib/timespec.h: Likewise.
* lib/nanosleep.c: Don't worry about TIME_WITH_SYS_TIME; no longer
needed.
* lib/strftime.c: Likewise.
* lib/timespec.h: Likewise.
* lib/posixtm.c: Include posixtm.h first, for interface check.
Don't worry about TM_IN_SYS_TIME; that's wayyy obsolete.
* lib/posixtm.h: Include stdbool.h and time.h, for proper interface.
* lib/strftime.c: Don't include <sys/types.h>; shouldn't be needed.
* lib/sys_time_.h: New file.
* lib/timespec.h (struct timespec): Use long int, not long.
* m4/gettimeofday.m4 (gl_FUNC_GETTIMEOFDAY):
(gl_FUNC_GETTIMEOFDAY_CLOBBER, gl_PREREQ_GETTIMEOFDAY):
Remove obsolescent call to AC_HEADER_TIME.
* m4/mktime.m4 (AC_FUNC_MKTIME): Likewise.
* m4/nanosleep.m4 (gl_FUNC_NANOSLEEP): Likewise.
* m4/strftime.m4 (gl_FUNC_STRFTIME): Likewise.
* m4/timespec.m4 (gl_TIMESPEC, gl_CHECK_TYPE_STRUCT_TIMESPEC):
Likewise.
* m4/tzset.m4 (gl_FUNC_TZSET_CLOBBER): Likewise.
* m4/utimbuf.m4 (gl_CHECK_TYPE_STRUCT_UTIMBUF): Likewise.
* m4/gettimeofday.m4 (gl_FUNC_GETTIMEOFDAY): Move sys/time.h tests
into the sys_time module. Check for gettimeofday just once.
Prefix our variables with gl_, not with ac_ or jm_. Tighten test
for gettimeofday signature to just check the signature. Merely
compile it, since linking doesn't test signature. Improve test for
whether gettimeofday.o is actually needed.
(gl_FUNC_GETTIMEOFDAY_CLOBBER): Renamed from
AC_FUNC_GETTIMEOFDAY_CLOBBER. All uses changed. Use
AC_RUN_IFELSE rather than AC_TRY_RUN. If clobbering, set
and define GETTIMEOFDAY_CLOBBERS_LOCALTIME.
(gl_GETTIMEOFDAY_REPLACE_LOCALTIME): Don't define
GETTIMEOFDAY_CLOBBERS_LOCALTIME; that's gl_FUNC_GETTIMEOFDAY_CLOBBER's
job. Don't define tzset; that's gl_FUNC_TZSET_CLOBBER's job.
* m4/mktime.m4 (AC_FUNC_MKTIME): Just include <time.h> rather
than worrying about sys/time.h.
* m4/nanosleep.m4 (gl_FUNC_NANOSLEEP):
Don't bother worrying about TIME_WITH_SYS_TIME.
* m4/stat-time.m4 (gl_STAT_TIME): Likewise.
* m4/posixtm.m4 (gl_POSIXTM): Remove obsolescent call to AC_STRUCT_TM.
* m4/sys_time_h.m4: New file.
* m4/tzset.m4 (gl_FUNC_TZSET_CLOBBER): Require gl_HEADER_SYS_TIME_H.
Don't include sys/time.h. Return from main rather than exiting.
Define TZSET_CLOBBERS_LOCALTIME, for consistency with other names;
all uses changed.
* modules/gethrxtime (Depends-on): Add sys_time.
* modules/gettime (Depends-on): Likewise.
* modules/gettimeofday (Depends-on): Likewise.
* modules/nanosleep (Depends-on): Likewise.
* modules/settime (Depends-on): Likewise.
* modules/tempname (Depends-on): Likewise.
* modules/utimens (Depends-on): Likewise.
* modules/gettimeofday (Files): Remove lib/gettimeofday.h.
(Include:) Change back to <sys/time.h>.
(Maintainer:) Add self.
* modules/sys_time: New file.
* modules/tempname (Depends-on): Add gettimeofday.
* tests/test-gettimeofday.c: Include <sys/time.h>
rather than gettimeofday.h.

Include <limits.h>, and use its INT_MAX to rewrite the
j loop so that it does not overflow 'int'. Problem reported by
Ralf Wildenhues in
<http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
Play it safe by shifting left by 1 rather than multiplying by 2,
as GCC is less likely to optimize this away when the value
is signed (when it assumes overflow leads to undefined behavior).
Also, don't assume time_t uses two's complement.

2821 is fixed.
* lib/mktime.c (guess_time_tm): Fix bug where mktime
returned the maximum time_t value rather than (time_t) -1.
Problem originally reported by William Bardwell
<http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
* m4/mktime.m4 (AC_FUNC_MKTIME): Sync from Autoconf.
Check for unistd.h too, since Autoconf doesn't assume POSIX.
Also:
2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
Add year_2050_test to catch glibc bug 2821
<http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
Prefer #ifdef to #if.
2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
Return from 'main' instead of calling 'exit'.

* .cppi-disable: Add regcomp.c, regex_internal.c, regex_internal.h,
stat-time.h.
* argmatch.h: Include verify.h
(ARGMATCH_VERIFY): Use verify rather than rolling our own.
(ARGMATCH_ASSERT): Remove; unused.
* canonicalize.c: Assume STDC_HEADERS.
* exclude.c: Include "strcase.h".
* regex_internal.h [!defined _LIBC]: Likewise.
* getusershell.c: Include stdio--.h rather than stdio.h
and stdio-safer.h.
(getusershell): Call fopen, not fopen_safer.
* save-cwd.c: Include fcntl--.h rather than fcntl.h.
Do not include unistd-safer.h.
(save_cwd): Don't call fd_safer; no longer needed
now that we include fcntl--.h.
* modules/argmatch (Depends-on): Add verify.
* modules/getloadavg (Depends-on): Depend on fcntl-safer, not
unistd-safer.
* modules/save-cwd (Depends-on): Likewise.
* backupfile.m4, calloc.m4, chown.m4, cloexec.m4, dup2.m4:
* fileblocks.m4, free.m4, ftruncate.m4, getcwd.m4, getpagesize.m4:
* getugroups.m4, group-member.m4, idcache.m4, link-follow.m4:
* mkstemp.m4, mktime.m4, mountlist.m4, nanosleep.m4, pathmax.m4:
* physmem.m4, posixver.m4, putenv.m4, safe-read.m4, same.m4:
* save-cwd.m4, stdio-safer.m4, unistd-safer.m4, unlinkdir.m4:
* userspec.m4, xgetcwd.m4, xreadlink.m4:
Don't bother checking for string.h, stdlib.h, unistd.h.
* fts.m4 (gl_FUNC_FTS_CORE): Don't require
AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK; that's now the lstat
module's job.
* jm-macros.m4 (gl_MACROS): Likewise.
* prereq.m4 (gl_PREREQ): Add gl_FUNC_LSTAT.
* backupfile.c: Use ARGMATCH_VERIFY, just in case.
* posixtm.c (posixtime) [lint]: Initialize *all* of tm0, not just
the .tm_year member, since otherwise gcc-4.0 would now warn about
tm_zone, tm_gmtoff, tm_isdst, tm_yday, tm_wday.
* quotearg.c (quotearg_n_options): Change code to be suboptimal, in
order to avoid an unsuppressible warning from gcc on 64-bit systems.
* lstat.m4 (gl_FUNC_LSTAT):
Use AC_LIBSOURCES to require lstat.c and lstat.h.
Remove obsolete comment.
* xreadlink.m4: Use AC_LIBSOURCES and AC_LIBOBJ.
