You can declare pointers of forward-declared classes and pass them around.

Why do you always post twice (or four times to be exact) ?
Sry, just realized microsoft site is messed and not working(using
google now).
Why don't you do what Igor or I told you in the other thread
("error C2027: use of undefined type 'A'") ?
I did what you said and it gave me:
a.h(10) : error C2065: 'g_main' : undeclared identifier
a.h(10) : error C2227: left of '->SomeDriver' must point to class/
struct/union/generic type
type is ''unknown-type''
main.h(18) : error C2040: 'g_main' : 'main *' differs in levels of
indirection from ''unknown-type''
