typedef int f;

struct A {

    friend void f(A &);

    operator int();

    void g(A a) {

        f(a);

    }

};



The declaration of void f(A &) introduces it into the global namespace by
3.3/4:"friend declarations (11.4) may introduce a (possibly not visible)
name into an enclosing namespace", where it conflicts with typedef int f.
It is ill-formed by 3.3/4 again, because the symbol 'f' designates two
different entities, neither of them designates a class and one of them does
not designate a function.
