1997-02-11 05:27  Ulrich Drepper  <drepper@cygnus.com>

	* locale/weight.h (collate_rules): It's an u_int32_t array.
	(get_weight): Compute initial SLOT value correctly.

1997-02-10 17:45  Ulrich Drepper  <drepper@cygnus.com>

	* string/argz-ctsep.c: Initialize *LEN when successful.

	* libio/vsnprintf.c: If MAXLEN is 0 return 0.
	* stdio/vsnprintf.c: Likewise.
	Reported by Philip Blundell <pjb27@cam.ac.uk>.

1997-02-06 13:49  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* rellns-sh: No need to check for existance of first parameter.
