Update.
2001-08-09 Ulrich Drepper <drepper@redhat.com> * libio/wfileops.c (_IO_wfile_seekoff): Don't even try to handle seeking with backup buffer present. Correct determining of internal buffer position. Reset also wide buffers if we reset the internal buffers. * libio/iofwide.c (_IO_fwide): Always determine file offset for wide streams. * libio/ioseekoff.c: Catch one unimplemented case. * libio/ftello.c: Don't abort if the wide stream has backup buffer. * libio/ftello64.c: Likewise. * libio/iofgetpos.c: Likewise. * libio/iofgetpos64.c: Likewise. * libio/ftell.c: Likewise. * libio/Makefile (tests): Add tst-ungetwc2. * libio/tst-ungetwc2.c: New file.
