You have to start thinking in the terms of what you are trying to model here.

Public inheritance should only ever be used to model an "isa" relationship, e.g. a dog is a animal, a square is a shape, etc.

Have a look at Scott Meyer's book Effective C++ for an excellent essay on what the various aspects of OO design should only ever be interpreted as.

Edit: I forgot to say that while the answers so far provided are technically correct I don't think any of them address the issues of what you are trying to model and that is the crux of your problem!
