Here is a test case:


#define ON

#ifdef ON
#define PP ::
#else
#define PP
#endif

struct A {};
struct B : A {};

template<class T>
A* creator()
{
    return new T;
}

namespace KJS
{
    struct C : A
    {
        friend A* PP creator<C>();

        A* getAPtr()
        {
            return PP creator<C>();
        }

    private:
        C(){}
    };

}

int main()
{
    return 0;
}


and the results:

only compiles when :: is ON/OFF

gcc 3.4.4: OFF
gcc 4.0.2: OFF
msvc 8.0 : ON
