(getwc): Define as macro.
(getwchar): Ditto.
(putwc): Ditto.
(putwchar): Ditto.
* libc/include/sys/reent.h (struct __sFILE): Add _mbstate member.
(struct __sFILE64): Ditto.
* libc/stdio/Makefile.am (ELIX_4_SOURCES): Add fgetwc.c, fgetws.c,
fputwc.c, fputws.c, fwide.c, getwc.c, getwchar.c, putwc.c, putwchar.c
