   Instead of outlining a wildly complicated piece of code could you please   
   explain what problem you are trying to solve because IME complex solutions are   
   usually unnecessary and doubly so if they will not compile.   
      
   The other issue in that where two classes are so intimately related it makes   
   sense to declare and define them in the same header file. Neither of your base   
   classes can be defined in ignorance of the other so placing them in separate   
   header files makes no    
   sense.
