I don't think we should use enums at all in the protocol
specification.  It should be unsigned int and the change should be
made separately.  Is this hunk here because portable-rpcgen has
problems with enum being declared there?

If we leave it here and just remove the 'enum' keyword, then we need
to also adjust

I see you Cc'd Eric, so I'd leave him some space to object, but unless
that happens, the patch looks fine to me without this particular hunk.
