Does derivation from structs rather than classes default
to public rather than private, as it is for classes?

How about if the struct contains a private part?

struct A {
	int x;
};

struct B : A {
};

struct C {
private:
	int x;
};

struct D : C {
};

main()
{
	A * p = new B;	// Is this legal?
	C * q = new D;	// Is this legal?
}

Obviously if this were explicitly public derivation then the 
initializers would be legal, but does the type of derivation default
to public for structs?
