+ regex: don't assume uint64_t or uint32_t
+ * lib/regcomp.c (init_word_char): Don't assume that the types
+ uint64_t and uint32_t exist. The C standard doesn't guarantee
+ them, and on some 32-bit compilers there is no uint64_t.
+ Problem reported by Gianluigi Tiesi in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2012-03/msg00154.html>.

+ mktime: sync from glibc
+ * config/srclist.txt: Uncomment mktime.c.
+ * lib/mktime.c: Sync from glibc master. This incorporates 3 changes.
+ First, indent with tabs, since glibc uses tabs and doesn't want to
+ change and we'd rather be identical to glibc. Also, two small
+ coding changes:
+ (isdst_differ): Use &&, not &, as && is the usual style.
+ (__mktime_internal): Rename local var from abs_diff to approx_abs_diff
+ for clarity.

+
+2012-05-23 Akim Demaille <akim@lrde.epita.fr>
+
+ announce-gen: Improve diagnostics.
+ * build-aux/announce-gen: When parsing command line options,

+
+ poll/select: prevent busy-waiting. SwitchToThread() only gives away
+ the rest of the current time slice to another thread in the current
+ process. So if the thread that feeds the file decscriptor we're
+ polling is not in the current process, we get busy-waiting.
+ * lib/poll.c: Use SleepEx(1, TRUE) instead of SwitchToThread().
+ Patch from Theodore Leblond.
+ * lib/select.c: Split polling out of the loop that sets the output
+ fd_sets. Check for zero result and loop if the wait timeout is
+ infinite.

+ Don't assume the buffer length is less than 2**32.
+ * lib/sha512.c (sha512_process_block): Likewise.
+ Here, the bug is present only in the rare case where the host does
+ not support uint64_t or where size_t is wider than 64 bits.
+ Use u64size to work around the problems.
+ * lib/u64.h (u64size): New macro.

+ * m4/fsusage.m4 (STAT_STATFS2_FRSIZE): Always define
+ when the member is available so it can be used as a fallback.

+ bootstrap: suppress stderr chatter
+ * build-aux/bootstrap (insert_sorted_if_absent, main program):
+ Omit unnecessary chatter to stderr. The main program chatter
+ was there only inadvertantly.
+
+ bootstrap: .gitignore files created by autopoint, libtool
+ I ran into this problem when bootstrapping the latest diffutils.
+ After './bootstrap', 'git status' reported lots of untracked files
+ m4/codeset.m4, m4/gettext.m4, etc. These files were created by
+ autopoint and do not need to be version-controlled.
+ * build-aux/bootstrap: Put into .gitignore the files that
+ autopoint and libtool create, by keeping track of files that exist
+ after but not before these programs are run.
+ (version_controlled_file): Move up. 2nd arg is now full file
+ name, not base name; this is more convenient. Put CVS at the end,
+ as it's now somewhat deprecated.

+
+ bootstrap: take advantage of POSIX shell features
+
+ The 'bootstrap' script offered by Gnulib script already uses POSIX
+ shell features (like $((...)) arithmetic expansions) that are not
+ supported by legacy Bourne shells like Solaris 10 /bin/sh. This
+ means that bootstrap must already be run using a proper POSIX shell,
+ which will thus provide more features, like ${var#pattern} parameter
+ expansion or inversion of a command exit status with '!'. We can
+ thus use these features to improve the clarity and the performances
+ of the bootstrap script.
+
+ Suggested by Eric Blake.
+
+ * build-aux/bootstrap: Prefer xpg4 parameter expansions over use
+ of sed/expr plus command substitutions, to save some forks. While
+ we are at it, prefer the POSIX $(...) form of command substitution,
+ rather than the legacy form `...` (since the former is visually
+ clearer and interacts better with quoting), and prefer the idiom:
+ "if ! CMD; then ACTION ..."
+ over the idiom:
+ "if CMD; then :; else ACTION ..."
+ which was required by legacy Bourne shells not supporting '!'.

+ fsusage: check for GNU/Linux statvfs problem dynamically
+ * lib/fsusage.c [STAT_STATVFS && __linux__ && (__GLIBC__||__UCLIBC__)]:
+ Define STAT_STATFS2_BSIZE too, since in this case the code now
+ checks dynamically whether statvfs is reliable, falling back on
+ Linux-style statfs otherwise.
+ (statvfs_works): New function, for dynamically testing statvfs.
+ (get_fs_usage) [STAT_STATVFS]: Use it.
+ * m4/fsusage.m4 (gl_FILE_SYSTEM_USAGE): Remove static check for
+ statvfs on GNU/Linux hosts, since it's now done dynamically.
