I posted this to comp.lang.c++ and am not getting any responses...
Maybe comp.std.c++ should be answering my question???

The main problem is that my compiler is not using a function pointer
as expected. (according to base pointers and derived obects...)

This was done with g++ and sgi's Delta C++ compiler(DCC)

I am hesitant to make a fuss over it because I am not sure that it
should compile... :)
