	* 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.
