* pwd/fgetpwent.c: Don't include ../nss/nss_files/files-parse.c to
	define parse_line function.
	(parse_line): #define to _nss_files_parse_pwent and
	add extern decl for that.

	* nss/nss_files/files-XXX.c (internal_getent): Return
	NSS_STATUS_TRYAGAIN for ERANGE error.

	* sysdeps/i386/strtok.S (LreturnNULL): Save current state ptr instead
	of null, so next round returns null again instead of bombing.  Fix
	from drepper.

	* nss/nss_files/files-parse.c (LINE_PARSER): Take new first arg EOLSET.
	Remove ; after `ENTDATA_DECL (data)'.
	Truncate line at strpbrk (line, EOLSET "\n").

	* elf/dl-load.c (_dl_map_object): Use any object with matching l_name
	as well as any matching with l_libname.  Fix DT_SONAME lookup to use
	string table properly.

	* elf/rtld.c (dl_main): Set _dl_rtld_map.l_name from _dl_argv[0] when
	invoked directly, and l_libname from that if PT_INTERP missing.
	Set l_name from l_libname only if not set from argv.

	* time/europe, time/northamerica: Updated from ADO 96i.

	* stdio-common/tst-ungetc.c: Include unistd.h.
