+ tests/nap.h: use an adaptive delay to avoid ctime update issues
+ The recent change in nap.h (5191133e) decreased the probability of lost
+ races to about a third, however such problems could still be observed
+ in virtual machines and openSUSE's OBS.
+ Before, nap() detected the needed time once empirically and then used
+ that delay (together with a small correction multiplier) in further
+ calls. This problem has been reported and discussed several times,
+ including guesses about possible kernel issues:
+ https://lists.gnu.org/archive/html/bug-gnulib/2013-04/msg00071.html
+ http://lists.gnu.org/archive/html/coreutils/2012-03/msg00088.html

+ https://lists.gnu.org/archive/html/bug-gnulib/2009-11/msg00007.html
+ Now, nap() avoids the race alltogether by verifying on a reference
+ file whether a timestamp difference has happened.
+ * tests/nap.h (nap_fd): Define file descriptor variable for the
+ witness file.
+ (nap_works): Change return value to bool. Change passing
+ the old file's status by value instead of by reference as this function
+ does no longer update that timestamp; rename the function argument from
+ st to old_st. Remove the local variables cdiff and mdiff because that
+ function now returns true/false instead of the precise delay.
+ (guess_delay): Remove function.
+ (clear_tmp_file): Add new function to close and unlink the witness file.
+ (nap): Instead of re-using the delay which has been calculated during
+ the first call, avoid the race by actually verifying that a timestamp
+ difference can be observed on the current file system. Use an adaptive
+ approach for the delay to minimize execution time. Assert that the
+ maximum delay is <= ~2 seconds, more precisely sum(2^n) from 0 to 30
+ = 2^31 - 1 = 2.1s.
+ Use atexit to call clear_tmp_file when the process terminates.

+ Some of these changes are merged in from git Autoconf.

+
+ unistd: avoid namespace pollution on non-glibc systems
+ * lib/unistd.in.h: #define __need_getopt before including <getopt.h>.

+
+ getcwd: break fdopendir + save_cwd recursive loop (Bug#13516)
+ Reported for OS X 10.8.2 by Assaf Gordon in
+ <http://bugs.gnu.org/13516>.
+ * lib/getcwd.c (HAVE_OPENAT_SUPPORT): Do not define if
+ !HAVE_OPENAT && !HAVE_FDOPENDIR.
+ * m4/getcwd-abort-bug.m4: Reformat to match test-getcwd.c
+ so that they can be kept in sync more easily. Avoid PATH_MAX
+ test on the Hurd. Sync from test-getcwd.c for errno tests after
+ mkdir or chdir failure.
+ * tests/test-getcwd.c (HAVE_OPENAT_SUPPORT): New macro, from
+ lib/getcwd.c.
+ (test_abort_bug): Do not test for the deep directory bug unless we
+ have openat support. Avoid PATH_MAX test on the Hurd.
+
+ regex-tests, regex: fix bug: memset undeclared
+ * tests/test-regex.c: Don't include regex.h twice. Include
+ string.h, to declare memset. Christensen's report also mentioned
+ this issue.
+ * m4/regex.m4 (gl_REGEX): Keep test program more in sync with
+ test-regex.c, to avoid future problems like this. Remove
+ AC_INCLUDES_DEFAULT. Include <string.h>. Don't include <regex.h>
+ twice.
+
+ regex-tests: fix link errors on older Solaris
+ These need to link with @LIBINTL@ to get libintl_gettext.
+ Problem reported by Tom G. Christensen in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2013-02/msg00003.html>.
+ * modules/regex-tests (test_regex_LDADD): New macro.
+
+2013-01-31 Paul Eggert <eggert@cs.ucla.edu>
+
+ regex-tests: new module
+ * modules/regex-tests, tests/test-regex.c: New files.
+
+ regex: fix off-by-one error in configure test
+ * m4/regex.m4 (gl_REGEX): Test should return 21, not 20.
+
+2013-01-31 Eric Blake <eblake@redhat.com>
+
+ regex: avoid infinite configure test
+ * m4/regex.m4 (gl_REGEX): Add an alarm escape hatch.
+
+2013-01-31 Reuben Thomas <rrt@sc3d.org>
+
+ openpty: fix bug where HAVE_OPENPTY wasn't defined
+ See the thread starting at:
+ http://lists.gnu.org/archive/html/bug-gnulib/2013-01/msg00185.html
+ * m4/pty.m4 (gl_FUNC_OPENPTY): Define HAVE_OPENPTY when the
+ openpty function exists, not merely when we intend to replace it.
+
+2013-01-30 Paul Eggert <eggert@cs.ucla.edu>
+
+ sys_time: port to Solaris 2.6
+ There is a circularity problem on Solaris 2.6, where <time.h> includes
+ <sys/time.h> for struct timespec. The include nesting is gnulib
+ <time.h>, system <time.h>, gnulib <sys/time.h>, system
+ <sys/time.h>, gnulib <sys/types.h>, system <sys/types.h>, gnulib
+ <sys/select.h>, gnulib <signal.h>, system <sys/signal.h>, system
+ <sys/siginfo.h>; the last, innermost file needs struct
+ timestruc_t, which is defined in <sys/time.h>, which has not been
+ fully parsed. Problem reported by Tom G. Christensen in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2013-01/msg00113.html>.
+ * lib/sys_select.in.h: Treat Solaris 2.6's problem with
+ <sys/time.h> and <sys/types.h> like OSF/1's similar problem.
+ * lib/sys_time.in.h: Redo to resemble sys_select.in.h, which
+ uses split double-inclusion guards.
+
+2013-01-29 Paul Eggert <eggert@cs.ucla.edu>
+
+ regex: test for buffer overrun
+ * m4/regex.m4 (gl_REGEX): Add test case, by Andreas Schwab,
+ for the just-fixed regex bug.
+
+2013-01-29 Andreas Schwab <schwab@suse.de>
+
+ regex: fix buffer overrun in regexp matcher [BZ #15078]
+ * lib/regexec.c (extend_buffers): Add parameter min_len.
+ (check_matching): Pass minimum needed length.
+ (clean_state_log_if_needed): Likewise.
+ (get_subexp): Likewise.
+
+2013-01-28 Pádraig Brady <P@draigBrady.com>
+
+ mountlist: don't consider "devtmpfs" as dummy
+ * lib/mountlist.c (ME_DUMMY_0): Remove "devtmpfs"
+ as there is storage associcated with it.
+
+2013-01-27 Paul Eggert <eggert@cs.ucla.edu>
+
+ futimens-tests, utimens-tests: Depend on gettext.
+ This works around a problem introduced in my 2013-01-12 patch,
+ which added @LIBINTL@ to these modules.
+ * modules/futimens-tests (Depends-on):
+ * modules/utimens-tests (Depends-on): Add gettext.

+
+2013-01-20 Bernhard Voelker <mail@bernhard-voelker.de>
+
+ bootstrap: remove the need for a sorted .gitignore file
+ * build-aux/bootstrap (insert_sorted_if_absent): Adjust and
+ rename to insert_if_absent(), so that we don't need or generate
+ a sorted .gitignore file. We do require a .gitignore with no
+ existing duplicate entries and enforce that.
+ (sort_patterns): Remove this function as we now use the simpler
+ technigue of inserting blacklist entries at the top of the file,
+ assuming gnulib won't be inserting !whitelist entries.
+
+2013-01-23 Paul Eggert <eggert@cs.ucla.edu>
+
+ readlinkat: don't depend on gl_FUNC_OPENAT
+ * m4/readlinkat.m4 (gl_FUNC_READLINKAT): Don't require gl_FUNC_OPENAT.
+ Perhaps a similar change needs to be made for linkat.m4, mkfifoat.m4,
+ renameat.m4, symlinkat.m4; but one thing at a time.
+
+ statat: new module, split out from fstatat
+ GNU Emacs needs the POSIX-specified fstatat, but not the
+ gnulib-specified statat and lstat. Split the latter two into a
+ new module 'statat'.
+ * lib/openat.h: Depend on GNULIB_STATAT, not GNULIB_FSTATAT.
+ * lib/openat.h, lib/statat.c (STATAT_INLINE):
+ Rename from FSTATAT_INLINE. All uses changed.
+ * modules/fstatat (Files): Remove lib/statat.c.
+ (gl_MODULE_INDICATOR([fstatat])): Remove.
+ (lib_SOURCES): Remove.
+ (Maintainer): Add self.
+ * modules/statat, modules/statat-tests, tests/test-statat.c: New files.
+ * tests/test-fstatat.c (BASE): Don't define if already defined.
+ (do_stat, do_lstat) [!TEST_STATAT]: Test fstatat instead.

+2013-01-21 Paul Eggert <eggert@cs.ucla.edu>
+
+ stpncpy: port to OS X 10.8
+ * lib/stpncpy.c (__stpncpy): Parenthesize name when defining function.

+
+2013-01-16 Paul Eggert <eggert@cs.ucla.edu>
+
+ unistd: port to recent mingw
+ * lib/unistd.in.h: Remove special invocation convention for mingw,

+ <http://lists.gnu.org/archive/html/bug-gnulib/2013-01/msg00100.html>.
+
+ largefile: port better to Mac OS X 10.5
+ This patch is backported from Autoconf git.
+ * m4/largefile.m4 (AC_SYS_LARGEFILE): Use AC_DEFINE, not
+ AH_VERBATIM, to define _DARWIN_USE_64_BIT_INODE, to avoid problems
+ with ino_t size being different for configuration time versus
+ build/run time. Problem reported by PHO in
+ <http://lists.gnu.org/archive/html/bug-autoconf/2013-01/msg00040.html>.
+
+2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
+
+ doc: clarify -Werror
+ * doc/warnings.texi (warnings): -Werror is not always a bad idea;

+ and mention --enable-gcc-warnings as one possible use.
+
+2013-01-15 Andoni Morales Alastruey <ylatuya@gmail.com> (tiny change)
+
+ stdint: fix build with Android's Bionic fox x86
+ * lib/stdint.in.h: fix check to test if included-fixed/sys/types.h

+
+ locale: port to Solaris 2.6 and 7 + GNU gettext
+ * lib/locale.in.h: Just include_next <locale.h> when

+ * lib/pthread.in.h (__need_system_stdlib_h):
+ * lib/unistd.in.h (__need_system_stdlib_h) [!__GLIBC__]:

+
+2013-01-05 Paul Eggert <eggert@cs.ucla.edu>
+
+ doc: avoid small caps
+ * doc/parse-datetime.texi, doc/regex.texi: Don't use small caps;

+
+ regex: conform to strict C
+ * lib/regcomp.c (parse_bracket_exp): Add cast to conform to strict C.
+ From Aharon Robbins.

+
+ fprintftime: bring back and reword fwrite comment
+ * lib/strftime.c (cpy) [FPRINTFTIME]: Re-add reworded comment.
+
+ stdio: remove now-unnecessary stdio.c
+ Since stdio.in.h no longer uses inline functions, we no longer
+ need to compile the extern versions.
+ * lib/stdio.c: Remove.
+ * modules/stdio (Files): Remove lib/stdio.c.
+ (lib_SOURCES): Remove.
+
+ unicodeio: depend on stdio, not ignore-value

+
+2013-01-03 Eric Blake <eblake@redhat.com>

+
+ update-copyright: avoid copyright notice date corruption
+ Given a sequence of copyright year numbers in which the final
+ one was a two-digit number that happened to be a substring of
+ a preceding four-digit year number, we would mistakenly update
+ the substring (from two- to four-digit) rather than the two-digit
+ number at the end, which, combined with the addition of the current
+ 4-digit year number would yield two 5-digit year numbers, e.g.,
+ here, it would convert the first "99" to "1999, 2013" rather than
+ the final one:
+ 1991, 99
+ 11999, 20131, 1999
+ * build-aux/update-copyright: Tighten a regexp.
+ * tests/test-update-copyright.sh: Add a test case to trigger the bug.

+
+ regex: omit needless signed-pointer casts
+ * lib/regcomp.c (build_charclass, build_charclass_op):
+ Use char *, not unsigned char *, for class name and extra.
+ The char values are always nonnegative so there's no need to
+ insist on unsigned char * here, and using char * removes the need
+ for casts. Reported by Aharon Robbins in
+ <http://sourceware.org/ml/libc-alpha/2012-12/msg00456.html>.
+
+ regex: support Gawk, which never uses alloca
+ * lib/regex_internal.h [!_LIBC && !HAVE_ALLOCA]:
+ Do not include in this case. Gawk doesn't supply a substitute
+ alloca.h and doesn't need one.
+
+ regex: port __libc_lock_define usage to C89
+ * lib/regex_internal.h (__libc_lock_define) [!_LIBC]: Remove.
+ (struct re_dfa_t): Use #ifdef instead. '__libc_lock_define (, lock)'
+ does not conform to C89, as it has an empty macro argument.

+ gettext: avoid obsolete macro AM_PROG_MKDIR_P
+ It is obsolete and is planned to be removed from Automake 1.14; see
+ <http://lists.gnu.org/archive/html/automake/2012-12/msg00029.html>.
+ * build-aux/po/Makefile.in.in (install-data, install-data-yes)

+ argp: port new 'inline' approach to Sun C 5.12 + Solaris 10
+ On this platform, we are not optimizing but we are using
+ the substitute for extern inlines, so compile as if

+ AC_PROG_MKDIR_P: port workaround to pre-2.62 Autoconf
+ * m4/gnulib-common.m4 (AC_PROG_MKDIR_P, AC_C_RESTRICT):
+ Use m4_ifndef([AC_AUTOCONF_VERSION], ...), not
+ m4_if(m4_version_compare(m4_defn([AC_AUTOCONF_VERSION]),[2.62]),[-1],
+ ...), as the latter is fatal with older Autoconfs.
+ Problem reported and fix suggested by Eric Blake in thread starting at
+ <http://lists.gnu.org/archive/html/bug-gnulib/2012-12/msg00097.html>.
+
+2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
+
+ AC_PROG_MKDIR_P: don't workaround if not buggy
+ * m4/gnulib-common.m4 (AC_PROG_MKDIR_P):
+ Define only for Autoconf versions before 2.62.
+ (AC_C_RESTRICT): Use documented AC_AUTOCONF_VERSION, not
+ undocumented m4_PACKAGE_VERSION, for consistency with the
+ abovementioned change to AC_PROG_MKDIR_P. This should suffice
+ since we're checking for 2.62 or later, and AC_AUTOCONF_VERSION
+ was introduced in 2.62.

+ x-to-1: honor $PERL
+ * build-aux/x-to-1.in: Run $HELP2MAN via $PERL so that the user gets
+ a chance to use his preferred version of Perl. This is typically
+ required by Darwin users whose default /usr/bin/perl does not have all
+ the libraries required by help2man, and who need to use their MacPorts
+ installation of Perl instead.

+ (main): Don't use cvsutils to get the list of unknown files,
+ just add all the existing files and directories.
