In other words - you cannot even *test* a pointer unless you are *sure*
there is a valid address in it.  I don't think so.  Is NULL some kind
of special exception?  Before we waste anymore bandwidth with this topic,
does anybody actually know a specific architecture and C compiler combination
that would cause a problem on a pointer compare?
