	* io/lockf.c (lockf): Clear fl before using.
	Patch by sr@adb.fr.

	* libio/strops.c: Correctly handle _IO_write_end.

	* nss/libnss_files.map: Add __nss_netgroup_parseline.
	* nss/nss_files/files-netgroup.c (_nss_netgroup_parseline): Don't
	panic if setnetgrent wasn't called before, return error.
	Patch by Thorsten Kukuk <kukuk@uni-paderborn.de>.

	* time/mktime.c: Define localtime_r function as my_mktime_localtime_r
	if locally defined.
	* time/strftime.c: Define localtime_r function as my_ftime_localtime_r
	if locally defined.
	Define tm_diff function as ftime_tm_diff if locally defined.
	Reported by Richard Stallman <rms@gnu.ai.mit.edu>.
