Someone else told you about forward declarations. IMO this is a
'smooth'  - well better solution anyway, although you should inline
the constructor if you really want the same functionality as you had. 

The public section of a class definition is your 'contract' with class
users (or clients), you shouldn't clutter it up with anything the
clients don't need to know - especially code. Kind of a philosphical
style thing. 

Cheers Terry...
