So is storing a Win32 HWND or a BeOS BWindow* as a void* in the
baseclass, but it's still platform dependent data (albeit in "hidden"
form) in XP code. What's wrong with putting this in the platform specific
classes?

Oh, but it does. If the class can't use the data because it doesn't know
what it is, why should that data be in that class in the first place? You
can't really *get* to that data, much less *set* it, without violating
some very basic design principles, and in that case that void* is
probably the lesser of the problems.
