+
+ fts, getcwd, glob: audit for dirfd returning -1
+ * lib/fts.c (opendir): Remove #define; no longer used.
+ (opendirat): New arg PDIR_FD. All callers changed.
+ (fts_build, _opendir2): Use new opendirat to avoid the need for
+ dirfd, or for checking whether dirfd returns a negative value.
+ Don't use opendir; always use openat followed by fdopendir.
+ * lib/getcwd.c (__getcwd): Don't reset fd; fdopendir no longer clobbers
+ it.
+ * lib/glob.c (link_exists_p): Add comment explaining why dirfd never
+ returns -1 here.
+ * modules/fts (Depends-on): Remove dirfd.
+ * modules/getcwd (Depends-on): Likewise.

+ float: fix broken MirBSD header
+ * m4/float_h.m4 (gl_FLOAT_H): MirBSD copied OpenBSD's bug.
+ * doc/posix-headers/float.texi (float.h): Document it.

+
+ fts: use O_NOFOLLOW to avoid race condition when opening a directory
+ * lib/fts.c (opendirat): New arg extra_flags.
+ (__opendir2): Use it to avoid following symlinks when opening
+ a directory, if symlinks are not supposed to be followed. See
+ <http://lists.gnu.org/archive/html/bug-gnulib/2010-09/msg00213.html>.
+
+ 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>.

+
+ regex: Pass the system regex if its only problem is 32-bit regoff_t.
+ * NEWS: Document change.
+ * m4/regex.m4: Disable test for regoff_t size.
+

+
+ fts: don't operate on an invalid file descriptor after failed dup
+ * lib/fts.c (fts_build): Don't call set_cloexec_flag on a
+ negative file descriptor.

+
+ 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.

+ langinfo: Fix last commit.
+ * m4/langinfo_h.m4 (gl_LANGINFO_H): Initialize
+ HAVE_LANGINFO_T_FMT_AMPM, HAVE_LANGINFO_YESEXPR.
+ Reported by Tom G. Christensen <tgc@jupiterrise.com>.

+
+ relocatable-prog-wrapper: Fix compilation failure due to O_EXEC.
+ * lib/progreloc.c (O_EXEC): Define fallback.
