  Well, crud.  One thing I suppose I could look into is using a few
other tricks to reduce compile time, especially re-compile time.  One
of which involves the obvious of replacing superfluous #includes with
class and struct declarations and adding the #includes back into the
implementation file.  Another trick advocated by Lakos in _C++ for
Large Scale Projects_ involves hiding the private section in a hidden
struct in the implementation file; the class declaration just has
pointer to the hidden structure.  This means that any dependent types
in the private section that required a #include can now use forward
declarations.  (If that's possible.  If they're really typedefs, then
you're still stuck with including the header. The same goes for any
dependent base class headers.)

Cheers!
