Update.
1999-08-22  Ulrich Drepper  <drepper@cygnus.com>

	* iconv/gconv_int.h (GCONV_AVOID_NOCONV): New definition.
	(__gconv_find_transform): Update prototype.
	(__gconv_open): Likewise.
	* iconv/gconv_open.c: Take extra parameter and pass it to
	__gconv_find_transform.
	* iconv/gconv_db.c (__gconv_find_transform): Take extra parameter with
	flags.  If GCONV_AVOID_NOCONV flag is set don't return copying
	transformation.
	* iconv/iconv_open.c: Pass extra parameter to __gconv_open.
	* wcsmbs/wcsmbsload.c: Likewise.
	* intl/dcgettext.c (_nl_find_msg): Rewrite to use gconv instead of
	iconv for glibc.
	* intl/gettextP.h: Likewise.
	* intl/loadmsgcat.c: Likewise.

	* posix/regexbug1.c: New file.
	* posix/Makefile (tests): Add regexbug1.
