Update.

2000-06-19  Ulrich Drepper  <drepper@redhat.com>

	* iconv/gconv.h (__gconv_trans_fct): Add new parameter.
	General namespace cleanup.
	(struct __gconv_trans_data): Add next field.
	(struct __gconv_step_data): Make __trans a pointer.
	* iconv/gconv_conf.c: Split out code to find gconv directories from
	__gconv_read_conf in new functions.
	* iconv/gconv_int.h: Define new data structure and declare new
	functions for handling of gconv directory list.
	* iconv/gconv_open.c: Allow more than one error handling step being
	used.  Call function to load error handling module if it is none
	of the builtin transformations.
	* iconv/gconv_close.c: Add code to free transliteration data.
	* iconv/gconv_trans.c: Add functions to load and unload modules
	implementing transliteration etc.
	* iconv/skeleton.c: Call all context functions now that more than
	one module is allowed.
	* iconv/loop.c (STANDARD_ERR_HANDLING): New macro.
	* iconv/gconv_simple.c: Use STANDARD_ERR_HANDLING macro for places
	where the full error handling using transliteration is needed.
	* iconvdata/8bit-gap.c: Likewise.
	* iconvdata/8bit-generic.c: Likewise.
	* iconvdata/ansi_x3.110.c: Likewise.

	* iconvdata/unicode.c: Likewise.
	* iconvdata/utf-16.c: Likewise.
	* libio/iofwide.c: Reset __trans member of __gconv_trans_data
	structure correctly after last change.
	* wcsmbs/btowc.c: Likewise.
	* wcsmbs/mbrtowc.c: Likewise.
