	* sysdeps/posix/getcwd.c [__GNU_LIBRARY__]: Include unistd.h.

	* io/fts.h (FTSENT): Define fts_compar member with prototype.

	* hurd/hurd.h: Use prototype in getcttyid decl.

	* stdlib/l64a.c: Fix typo in last change.

	* stdlib/drand48-iter.c: Test limits.h macros instead of sizeof
	for determining size of types.
	* stdlib/srand48_r.c: Likewise.

	* misc/utmp.h: Declare login, logout, logwtmp.
	* misc/logout.c: Declare argument as pointer to const.
	* misc/login.c: Likewise.
	* misc/logwtmp.c: Likewise.
	Include time.h, string.h.

	* misc/efgcvt_r.c: Include stdlib.h.

	* io/mknod.c: Include sys/types.h.

	* gmon/sys/gmon.h: Declare monstartup, _mcleanup.

	* csu/gmon-start.c (_start, etext): Declare with prototypes.
