1999-04-30  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* string/bits/string2.h (memset): Revert to previous version if
	unaligned writes are not available.

1999-04-30  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/i386/i486/bits/string.h (__memset_gc): Help generating
	better code in presence of the asm.

	* stdlib/fmtmsg.c (keywords): Increase array size for faster
	indexing.

	* locale/localeinfo.h (_nl_category_names): Increase array element
	size for faster indexing.
