2000-07-20  Ulrich Drepper  <drepper@redhat.com>

	* libio/Makefile (tests): Add tst_wprintf2.
	(tst_wprintf2-ARGS): Define.
	* libio/tst_wprintf2.c: New file.
	Based on a test case by Yoshito Kawada <KAWADA@jp.ibm.com>.

	* libio/wfiledoalloc.c: Only allocate external buffer if this
	hasn't happened yet.

	* libio/wfileops.c (_IO_wdo_write): Overflow only if there is really
	something in the buffer.  gconv call can write up to end of the
	buffer, not only _IO_write_end.
	(_IO_wfile_overflow): Allocate also external buffer.

	* stdio-common/vfprintf.c (process_string_arg): Handle multibyte
	strings with precision in vfwprintf correctly.
	* stdio-common/vfprintf.c: Fix completely broken handling of
	unbuffered wide character streams.
	Reported by Yoshito Kawada <KAWADA@jp.ibm.com>.
