I had asked a question about this a while ago, and never got it working
till just now.  I kept getting the warning about releasing a pointer to an
undefined class.  I realized that it was because I was returning a
shared_ptr by value from a function.  Even though the function was not
called it warned about not being able to destruct the return.  BTW, MSVC 6
sp3.  Another item to add to the list of things to check for in a forward
declaration situation.
