Ulrich Drepper f1d5c60dde Update.
2000-06-15  Ulrich Drepper  <drepper@redhat.com>

	* iconv/gconv.h (__gconv_fct): Change type of fifth parameter to
	unsigned char **.
	(__gconv_init_fct): Remove two parameters.
	* iconv/gconv_int.h (__gconv_transliterate): Renamed from
	gconv_transliterate.  Remove two parameters.
	Change prototypes of builtin functions according to __gconv_fct change.
	* iconv/skeleton.c: Change type of fifth parameter.  make sure it is
	!= NULL only during error handling.  Stop in this case after the
	conversion.
	* iconv/gconv_trans.c: Replace with real implementation for
	__gconv_transliterate.
	* iconv/gconv_open.c: Adjust for renaming of __gconv_transliterate.
	* iconv/gconv.c: Change calls to downstream functions once again.
	Use NULL for the fifth parameter instead of pointer to output buffer.
