+
+ fdopendir: preserve argument fd before returning
+ * lib/fdopendir.c: Adjust comments to say POSIX, not Solaris.
+ (fdopendir_with_dup, fd_clone_opendir): New static functions.
+ (fdopendir): Use them, arranging for FD to be open to the same
+ directory that it was when it started. (It might be temporarily
+ closed while fdopendir is running, so this not thread- or
+ signal-safe.) Be careful to do the right thing even when file
+ descriptors are scarce and dup fails with errno == EMFILE. See
+ <http://lists.gnu.org/archive/html/bug-gnulib/2010-09/msg00208.html>.

+
+ savedir: add streamsavedir, deprecate fdsavedir
+ * NEWS: Mention deprecation of fdsavedir.
+ * lib/savedir.c (streamsavedir): New extern function, whose name
+ ends in "savedir" to be consistent with the others. This differs
+ from savedirstream in that it doesn't close its argument. The
+ next version of GNU tar will use this instead of fdsavedir, to
+ avoid some race conditions and conserve file descriptors.
+ (savedirstream): Reimplement as a wrapper around streamsavedir.
+ (fdsavedir): Add a comment deprecating this function. As far as
+ I know, only GNU tar used it, and GNU tar doesn't need it any more.
+ * lib/savedir.h (streamsavedir): New decl.
+ (fdsavedir): Add a comment deprecating this.

+
+ fcntl-h: define O_CLOEXEC and O_EXEC if not defined; use new defines
+ * NEWS: Document recent changes to fcntl-h.
+ * doc/posix-headers/fcntl.texi (fcntl.h): Document that
+ O_CLOEXEC is now defined to 0 if it is not defined, like other flags.
+ Also, O_EXEC is now defined to be O_RDONLY if O_EXEC is not defined.
+ Similarly for O_SEARCH; this last was already true, but not documented.
+ * lib/fcntl.in.h (O_CLOEXEC): Define to 0 if not defined.
+ * lib/dup-safer-flag.c (O_CLOEXEC): Remove now-useless #define.
+ * lib/dup3.c, lib/pipe2.c, tests/test-dup-safer.c, tests/test-fcntl.c:
+ Likewise.
+ * lib/popen-safer.c (open_noinherit): Check whether O_CLOEXEC

+ * lib/langinfo.in.h (T_FMT_AMPM, GNULIB_defined_T_FMT_AMPM): Define if
+ HAVE_LANGINFO_T_FMT_AMPM is 0.
+ (YESEXPR, NOEXPR, GNULIB_defined_YESEXPR): Define if
+ HAVE_LANGINFO_YESEXPR is 0.
+ * lib/nl_langinfo.c (rpl_nl_langinfo): Handle also T_FMT_AMPM, YESEXPR,

+
+ init.sh: penalize a set-x-impaired shell; don't disqualify it
+ * tests/init.sh: Too many shells corrupt application stderr when
+ you set -x, so we can't afford to disqualify them, since at least
+ on Irix-6.5, that would disqualify all bourne shells.
+ Instead, use a two-pass approach.
+ On the first pass, try to find a shell that meets the stricter
+ condition that set -x does not corrupt stderr.
+ If no shell meets the stricter condition, retest each candidate
+ shell, but without that extra condition. Finally, when
+ VERBOSE=yes is requested and set -x might cause trouble, simply
+ issue a warning and refrain from enabling debug output.

+ empty variable. Speed up awk script.
