Update.
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>.
