    OK, fine, let's do that. It's no less efficient, since the compiler
    will likely generate the same code either way. Put a note above the
    changed code that we did it for the Redhat folks.

    That said, we should make "put tcptrace sources into a CVS tree on
    masaka" a high priority item.
