+ getcwd: support coreutils better
+ Like strtod, getcwd incorrectly referred to HAVE_RAW_DECL_GETCWD,

+ * lib/getcwd.c (__getcwd): Do not depend on HAVE_RAW_DECL_GETCWD.
+ * m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX):

+ * m4/getcwd.m4 (gl_FUNC_GETCWD):
+ Don't define HAVE_MINIMALLY_WORKING_GETCWD if the code doesn't
+ compile, as might happen if there's a macro but no function.
+
+ strtod: support coreutils better
+ * lib/strtod.c (underlying_strtod): Just invoke the underlying strtod.
+ HAVE_RAW_DECL_STRTOD might not be correct in coreutils, which

+ GNU Emacs's <config.h> includes <stdlib.h> (which is not a great

+ Problem reported by Mats Erik Andersson in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2013-02/msg00051.html>.
+ * m4/pty.m4 (gl_FUNC_OPENPTY): Define HAVE_OPENPTY when the

+
+ extensions: port better to MINIX 3, HP-UX, autoheader 2.62
+ Some of these changes are merged in from git Autoconf.
+ * m4/extensions.m4 (AC_USE_SYSTEM_EXTENSIONS):
+ When deciding whether to define _XOPEN_SOURCE, inspect the
+ preprocessor macro __hpux instead of the more-heavyweight
+ operation of requiring AC_CANONICAL_HOST. Define _NETBSD_HOST on
+ MINIX, for MINIX 3. Use USE_SYSTEM_EXTENSIONS, not __EXTENSIONS__,
+ as the key for __EXTENSIONS__.
+
+ unistd: avoid namespace pollution on non-glibc systems
+ * lib/unistd.in.h: #define __need_getopt before including <getopt.h>.
+ This avoids namespace pollution on non-glibc systems, by causing
+ gnulib unistd.h to behave more like glibc unistd.h. I also hope
+ that this fixes a bug on FreeBSD, reported by Mats Erik Andersson in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2013-02/msg00027.html>.

+
+ unistd: port to recent mingw
+ * lib/unistd.in.h: Remove special invocation convention for mingw,

+
+ 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
+ was already included as _SSIZE_T_DEFINED_ might also be defined

+ net_if-tests: port to older Solaris
+ Problem reported by Tom G. Christensen in

+ Problem reported by Tom G. Christensen in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2013-01/msg00086.html>.

+
+ locale: port to Solaris 2.6 and 7 + GNU gettext
+ * lib/locale.in.h: Just include_next <locale.h> when
+ being invoked recursively. This prevents problems on Solaris 2.6 and 7
+ when combining the localename module with GNU gettext 0.18.2.
+ Problem reported by Tom G. Christensen in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2013-01/msg00084.html>.

+ Problem reported by Tom G. Christensen in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2013-01/msg00059.html>.

+ * lib/getopt.in.h (__need_system_stdlib_h):
+ * lib/pthread.in.h (__need_system_stdlib_h):
+ * lib/unistd.in.h (__need_system_stdlib_h) [!__GLIBC__]:
+ Define when including <stdlib.h>, to avoid problems at least for
+ the pthread case on Solaris 2.6 and 7. These .h files can get by
+ with the system stdlib.h.

+
+ doc: update main copyright year
+ * doc/gnulib.texi: Update copyright date.

+ doc: improve ISO 8601 discussion
+ * doc/parse-datetime.texi (Combined date and time of day items):
+ Specify more carefully what formats are supported and what is
+ done with excess precision.
+
+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;
+ they're more trouble than they're worth. Suggested by Karl Berry
+ in <http://bugs.gnu.org/13360>.
+
+ regex: conform to strict C
+ * lib/regcomp.c (parse_bracket_exp): Add cast to conform to strict C.
+ From Aharon Robbins.
+
+ gnulib-tool: fix incompatibility with autopoint 0.18.2
+ * gnulib-tool: Don't indent AM_GNU_GETTEXT_VERSION line.

+2013-01-04 Paul Eggert <eggert@cs.ucla.edu>
+
+ 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
+ * lib/unicodeio.c: Do not include ignore-value.h.
+ (fwrite_success_callback): Use plain fwrite, not ignore_value + fwrite.
+ * modules/unicodeio (Depends-on): Depend on stdio, not ignore-value.
+
+ fprintftime: depend on stdio, not ignore-value
+ * lib/strftime.c [FPRINTFTIME]: Do not include ignore-value.h.
+ (cpy) [FPRINTFTIME]: Use plain fwrite, not ignore_value of fwrite,
+ since the stdio module arranges to silence that warning now.
+ * modules/fprintftime (Depends-on): Depend on stdio, not ignore-value.
+
+2012-10-04 Simon Josefsson <simon@josefsson.org>
+
+ stdint-tests: Fix expanded-before-required-warning.
+ * modules/stdint-tests (Depends-on): Use AC_REQUIRE.
+
+2013-01-03 Paul Eggert <eggert@cs.ucla.edu>
+
+ fwrite: silence __wur only for older glibc versions
+ * lib/stdio.in.h (fwrite): Limit workaround to glibc 2.4 through 2.15.
+ This will help us remove this workaround some time in the far future.
+
+2013-01-03 Eric Blake <eblake@redhat.com>
+
+ fwrite: silence __wur without using inline
+ * lib/stdio.in.h (fwrite): Limit warn_unused_result workaround to

+ * modules/stdio (Depends-on): Drop extern-inline.

+
+ 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.
+ Reported by Aharon Robbins in
+ <http://sourceware.org/ml/libc-alpha/2012-12/msg00456.html>.

+2012-12-31 Eric Blake <eblake@redhat.com>
+
+ sigprocmask-tests: skip test if pid is unexpectedly large
+ * tests/test-sigprocmask.c (main): Add range check.
+
+ git-version-gen: avoid test -z portability glitch
+ * build-aux/git-version-gen: Prefer portable test spelling, since
+ git-version-gen is run on more than just developer machines.
+
+2012-12-31 Peter Rosin <peda@lysator.liu.se> (tiny change)
+
+ git-version-gen: add --fallback option to use if git is not present
+ * build-aux/git-version-gen: Add support for the new option --fallback,
+ which comes into play when there is no $tarball_version_file and
+ git is not working.
+ (scriptversion): Update.
+
+ maint.mk: handle missing git with more grace
+ * top/maint.mk (no-submodule-changes, public-submodule-commit):
+ Quietly proceed if git is not present.

+ * modules/regex (Depends-on): Remove localcharset.
+
+ regex: revert single-byte change
+ * lib/regexec.c (check_node_accept_bytes): Revert previous change
