[BZ #391]

2004-09-20  Roland McGrath  <roland@frob.com>
	* elf/dl-load.c (__stack_prot): Only use PROT_GROWSUP/PROT_GROWSDOWN
	in initializer #if defined.

2004-09-18  Paul Eggert  <eggert@cs.ucla.edu>

	[BZ #391]
	* stdlib/getsubopt.c: Merge fixes from gnulib.
	(__strchrnul) [!_LIBC]: Define and include "strchrnul.c".
	(getsubopt): Use prototypes, not K&R style.
	Fix bug: memcmp(A,B,N) was being invoked on a memory block B
	whose size might be smaller than N.  Use strncmp to avoid the bug.
