Possibly a decent idea.

The only problem is the use of virtual functions. I don't know
specifically about DJGPP, but vtabs usually have a little bit of
overhead associated with them. Why not use function pointers,
initialised by the specific constructors? It's still not *quite* as fast
a specific call, but there might be a way around that, too.
