        * libc/stdio/stdio.c (__swrite): declare "oldmode" only if it's
        used later (ifdef __SCLE)
        * libc/stdio/vfscanf.c (__svfscanf): declare "state" only if it's
        used later (ifdef MB_CAPABLE)
        * libc/string/memset.c (memset): removed unused variables "count"
        and "unaligned_addr"
        * libc/locale/locale.c (_setlocale_r): declare "lc_ctype" and
        "last_lc_ctype" only of they're used later (ifdef MB_CAPABLE)
        * libc/unix/getpwent.c (getpwnam): removed unused variables "uid"
        and "gid"

         * libc/stdlib/envlock.c: changed documented "__env_lock" and
         "__env_unlock" prototype from "void *" or "char *" to
         "struct _reent *" to match real function.  Also added include
