	* iconv/gconv_int.h: New file.  Internal header.
	* iconv/Makefile (distribute): Add gconv_int.h.
	* iconv/gconv.h: Remove definition which are now in gconv_int.h.
	* iconv/gconv_builtin.c: Adopt for gconv_int.h introduction.
	* iconv/gconv_close.c: Likewise.
	* iconv/gconv_conf.c: Likewise.
	* iconv/gconv_db.c: Likewise.
	* iconv/gconv_dl.c: Likewise.
	* iconv/gconv_int.h: Likewise.
	* iconv/gconv_open.c: Likewise.
	* iconv/iconv.c: Likewise.
	* iconv/iconv_close.c: Likewise.
	* iconv/iconv_open.c: Likewise.
	* iconv/iconv_prog.c: Likewise.

1998-04-03  Ulrich Drepper  <drepper@cygnus.com>

	* iconvdata/ksc5601.c: Correct Perl scripts and make them omit the
	missing braces.
