Accepted, however I don't know of another way.  If any cunning artificers
out there have one I would be glad to here of it :-)

One possible workaround - does gcc support zero sized base classes at all,
on any platforms?  If not then I could just cripple is_empty for the gcc
case (this is seriously unpretty, but may be better than the warning if
empty base classes aren't supported anyway).
