	* sysdeps/generic/strrchr.c: Deansideclized.

	* elf/Makefile (ldd): Depend on Makefile.
	Find ld.so in $(slibdir) instead of $(libdir).

	* sysdeps/i386/strrchr.S: Use `testl $3, %esi' instead of `testb $3,
	%esi'; gas misassembles the latter into `testb $3, %dh'.

	* mach/Machrules (%.udeps rule): Do $(make-target-directory) first.

Tue May 14 16:38:44 1996  David Mosberger-Tang <davidm@AZStarNet.com>

	* sunrpc/getrpcent.c (interpret): Declare args.  Rewrite parsing using
	strpbrk.

Tue May 14 20:18:38 1996  Ulrich Drepper  <drepper@cygnus.com>

	* time/Makefile (routines): Add strptime.
	* time/time.h: Add prototype for strptime.
	* time/strptime.c: New file.  Implementation according to XPG4.
