    POSIX requires that uid_t be an arithmetic type, and does not
    specify whether it's signed or not.  Some POSIX-conforming systems
    have uid_t defined as type unsigned long.  Which raises some
    interesting questions when it's time to make NFS work, but that's
    another story...

    By the way, ULTRIX 4.0 seems to accept user IDs between 32000 and
    32767.  At least, chmod() returns without error when I give it
    32700 as a user ID and as a group ID.
