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.
