        * libc/stdio/getwchar.c: New file, implementing getwchar and
        _getwchar_r.
        * libc/stdio/local.h (ORIENT): New macro.
        * libc/stdio/puts.c (_puts_r): Set stream orientation.
        * libc/stdio/putwc.c: New file, implementing putwc and _putwc_r.
        * libc/stdio/putwchar.c: New file, implementing putwchar and
        _putwchar_r.
        * libc/stdio/refill.c (__srefill_r): Set stream orientation.
        * libc/stdio/stdio.tex: Add documentation for new functions.
