(__SWID): Define. * libc/include/wchar.h: Add declarations for new wide char functions. (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 and ungetwc.c. (CHEWOUT_FILES): Add fgetwc.def, fgetws.def, fputwc.def, fputws.def, fwide.def, getwc.def, getwchar.def, putwc.def, putwchar.def and ungetwc.def. Add header dependency rules for the new files. * libc/stdio/Makefile.in: Regenerate. * libc/stdio/fgetwc.c: New file, implementing fgetwc and _fgetwc_r. * libc/stdio/fgetws.c: New file, implementing fgetws and _fgetws_r. * libc/stdio/findfp.c (std): Initialize FILE's _mbstate member. (__sfmoreglue): Ditto. * libc/stdio/fputs.c (_fputs_r): Set stream orientation. * libc/stdio/fputwc.c: New file, implementing fputwc and _fputwc_r. * libc/stdio/fputws.c: New file, implementing fputws and _fputws_r. * libc/stdio/fread.c (_fread_r): Set stream orientation. * libc/stdio/freopen.c (_freopen_r): Reset stream orientation. Reset _mbstate. * libc/stdio/fseek.c (_fseek_r): Reset _mbstate. * libc/stdio/fwide.c: New file, implementing fwide and _fwide_r. * libc/stdio/fwrite.c (_fwrite_r): Set stream orientation. * libc/stdio/getwc.c: New file, implementing getwc and _getwc_r. * 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. * libc/stdio/ungetc.c (_ungetc_r): Set stream orientation. * libc/stdio/ungetwc.c: New file, implementing ungetwc and _ungetwc_r. * libc/stdio/vfscanf.c (__SVFSCANF_R): Set stream orientation. * libc/stdio/wbuf.c (__swbuf_r): Ditto.
