Ulrich Drepper 9ce5071a3d Update.
1998-04-21 19:05  Ulrich Drepper  <drepper@cygnus.com>

	* iconv/gconv.h (struct gconv_step): Add element stateful.
	* iconv/gconv_builtin.c (__gconv_builtin_trans): Initialize stateful
	to zero for all internal conversions.
	* iconv/skeleton.c: Initialize stateful depending on whether or not
	RESET_STATE is defined to one or zero respectively.
	* stdlib/mblen.c: Use stateful element of currently selected
	converter for result if S is NULL.
	* stdlib/mbtowc.c: Likewise.
	* stdlib/wctomb.c: Likewise.
