 	* libposix/bootstrap (posix_list): remove unnecessary temp file
 
+2010-12-29  Eric Blake  <eblake@redhat.com>
+
+	mountlist: tweak previous commit
+	* lib/mountlist.c (me_remote): Guarantee trailing backslash.
+	Reported by Paul Eggert.
+
+	mountlist: fix local drive detection on cygwin
+	* lib/mountlist.c (ME_REMOTE) [__CYGWIN__]: Provide implementation
+	that works for cygwin.
+
+2010-12-29  Paul Eggert  <eggert@cs.ucla.edu>
+
+	ftoastr, snprintf: ftoastr + snprintf module
+	* lib/ftoastr.c: Use GNULIB_SNPRINTF, not GNULIB_SNPRINTF_POSIX,
+	since the snprintf module now should be good enough here.
+	* modules/snprintf (configure.ac): Add gl_MODULE_INDICATOR([snprintf]).
+	It seems odd to have both gl_STDIO_MODULE_INDICATOR([snprintf])
+	and gl_MODULE_INDICATOR([snprintf]), but the former enables
+	GNULIB_SNPRINTF only for the test directory, and the latter
+	doesn't arrange for gl_STDIO_H_DEFAULTS to be called, so neither
+	seems to suffice by itself.
+
+2010-12-28  Paul Eggert  <eggert@cs.ucla.edu>
+
+	alloca: one step towards thread-safety
+	* lib/alloca.c (find_stack_direction): New arg PTR, to avoid the
+	need for a static variable.  All callers changed.  This does not
+	make the alloca replacement thread-safe, but it's one step.
+
+	tests: minor indenting change
+	* tests/init.sh: Sync from coreutils housekeeping patch
+	<http://lists.gnu.org/archive/html/coreutils/2010-12/msg00116.html>
+	to keep lines within 80 columns.
+
+2010-12-28  Jim Meyering  <meyering@redhat.com>
+
+	regex: don't infloop on persistent failing calloc
+	* lib/regexec.c (build_trtable): Return failure indication upon
+	calloc failure.  Otherwise, re_search_internal could infloop on OOM.
+	In glibc, this was fixed for version 2.13:
+	http://sourceware.org/bugzilla/show_bug.cgi?id=12348

+
+	linkat: Make implementation robust against system behaviour variations.
+	* m4/link-follow.m4 (gl_FUNC_LINK_FOLLOWS_SYMLINK): Define
+	LINK_FOLLOWS_SYMLINKS to -1 if it needs a runtime test in the Solaris
+	way, and to -2 if it needs a generic runtime test.

+	solaris_optimized_link_follow): New functions.
+	* tests/test-linkat.c (EXPECT_LINK_HARDLINKS_SYMLINKS): New macro.
+	(check_same_link): Use it.

+
+	tests: port test-fdutimensat.c to Solaris 8
+	* tests/test-fdutimensat.c (do_fdutimens): Don't assume
+	fdutimensat works with a nonnegative fd and AT_SYMLINK_NOFOLLOW.
+	On Solaris 8, it fails with errno == ENOSYS, because there is no
+	futimens (so it can't use the fd), and there is no lutimens (so it
+	can't implement AT_SYMLINK_NOFOLLOW on symlinks).
+
+	vsnprintf: make more consistent with snprintf; doc fixes

+
+	doc: document Solaris printf bug with large float precisions
+	* doc/posix-functions/dprintf.texi (dprintf):
+	* doc/posix-functions/fprintf.texi (fprintf):
+	* doc/posix-functions/printf.texi (printf):

+	* doc/posix-functions/vprintf.texi (vprintf):
+	* doc/posix-functions/vsnprintf.texi (vsnprintf):
+	* doc/posix-functions/vsprintf.texi (vsprintf):
+	Mention that these functions mishandle large floating point
+	precisions on Solaris 10.  The same bug is also present in Solaris
+	8, and I assume earlier.  This causes "cd gnulib-tests; make
+	check" to fail on Solaris 8 (and I assume, later) when building
+	the latest coreutils, in test-vasprintf-posix's call to
+	my_asprintf (&result, "%.4000f %d", 1.0, 99).  I have not checked
+	the wide flavors (e.g., wprintf) so this patch just updates the
+	documentation for the narrow ones.
+
+	test-posixtm.c: add two tests
+	* tests/test-posixtm.c: Add two tests, to highlight the
+	bug in Solaris 10 (and earlier) localtime.  Gnulib doesn't work
+	around this bug; this is merely to document it.
+
+2010-12-22  Bruno Haible  <bruno@clisp.org>
+
+	getlogin_r: Work around portability problem on OSF/1.
+	* m4/getlogin_r.m4 (gl_FUNC_GETLOGIN_R): Detect the OSF/1 problem.
+	* lib/unistd.in.h (getlogin_r): Replace if REPLACE_GETLOGIN_R is set.
+	* lib/getlogin_r.c (getlogin_r): When getlogin_r exists, invoke it and
+	test for a truncated result.
