Well I don't think this is guarenteed sizeof(void (X::*)(void) == 
sizeof(void (Y::*)(void). But I'm basing my assumption the VC++ 
compilers implementation which is often a risky thing to do. VC++'s 
pointer to members vary in size based on the type, mainly plain 
inheritance, multiple inheritance and virtual base class involvement.
