Well, the real bug is that I created all those operator=() wrong - the 
correct way is to return a reference to the class. Declaring operator=() may 
be required for abstract classes too since noone stops you from having 
abstract classes with data members. A derived class then must call 
operator=() of the abstract base class in it's own operator=().
Just changing the return value to Component& (not const &) should remove the 
compile errors for good.
I'll do this for every operator=() very soon anyway so a little bit of 
waiting will remove the work for you. ;-)
