2001-03-19  Rodney Brown  <RodneyBrown@mynd.com>

	Remove `might be used uninitialized' warnings.
	* call.c (convert_like_real): Unconditionally initialize `savew' and
	`savee' in `BASE_CONV' case.
	(joust): Initialize `w' and `l'.
	* init.c (build_java_class_ref): Initialize `name', minor reformatting.
