Update.

	* iconv/gconv_db.c: Don't define lock as static.  Rename to
	__gconv_lock and export from the file.
	* iconv/gconv_int.h: Declare __gconv_lock.
	* libio/iofclose.c [_LIBC] (_IO_new_fclose): Lock gconv lock
	before __gconv_release_step calls.
	Patch by Shunichi Sagawa <s-sagawa@jp.fujitsu.com>.

	* iconv/gconv_simple.c (internal_ucs4_loop): Fix typo in last change.
