Update.

1998-12-21  Ulrich Drepper  <drepper@cygnus.com>

	* inet/gethstbynm_r.c: Remove NEED__RES definition since we do this
	anyway for digits_dots.c.
	* nss/getXXbyYY.c: Initialize _res before using digits_dots.c
	functions.
	* nss/getXXbyYY_r.c: Likewise.

1998-12-19  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de> 
 
	* sunrpc/key_call.c (getkeyserv_handle): Use __fcntl instead of 
	fcntl.
 
1998-12-20  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de> 
 
	* locale/weight.h (get_weight): Extract string elements as 
	unsigned values.
