Are you sure this can't be worked around using varargs macros?
#define CREATABLE_CLASS(name, ...) \
extern class OBJECT* create_##name( __VA_ARGS__ ); \
=== For declaring an object
#define CREATABLE_CLASS(name) \
extern class OBJECT* create_##name( int argc, const char* argv[] ); \
class name : virtual public OBJECT
=== So main.cpp doesn't need the headers for every class
#undef CREATABLE_CLASS
#define CREATABLE_CLASS(name) \
extern class T_OBJ* create_##name( int argc, const char* argv[] );
#include "objects.def"
Bad idea, I think. You now have two separate bits of code that are
generating the prototypes for this set of functions. [snip]
