Hello Michael...

Please don't do this ( unless you know EXACTLY what you are doing)...
it is against the elementary norms of pogramming.

[I gather that the C++ standards committee came very close to defining
the structure of a vtbl, so portable code could mess with them. I
suspect you'll find that no matter which compiler you use, the vtbls are
all about the same. -John]
