        * libc/include/stdio.h[_REENT_SMALL]: Do not allow macros
        for clearerr, feof, or fileno.
        * libc/include/sys/reent.h[_REENT_SMALL](struct _reent): Change
        the dummy std stream scheme to use pointers to const external
        fake files, one for each standard stream.
        * libc/stdio/local.h (CHECK_INIT): Change to take a file pointer
        argument.  For _REENT_SMALL, reset the file pointer if it
        matches one of the fake std stream pointers.
        * libc/stdio/clearerr.c: Fix CHECK_INIT macro to add file pointer
        argument.
