Because of the mutual dependency in the definitions of classes A and B, you
can't *define* the functions func1 and func2 within their respective class
definitions.  They can still be inline, if that's important.  Just move the
function definitions after both of the necessary classes are defined.

class A {
public:
	class B func1();
};

class B {
public:
	class A func2();
};

inline B A::func1() { ... }
inline A B::func2() { ... }
