>Description:
>>From the example in section 7.3.3 12 of the 1997 draft,
gcc complains about the "using C::f" declaration.
>How-To-Repeat:
from http://anubis.dkuug.dk/jtc1/sc22/open/n2356/dcl.html:
namespace B {
        void f(int);
        void f(double);
}
namespace C {
        void f(int);
        void f(double);
        void f(char);
}
void h()
{
        using B::f;   // B::f(int) and B::f(double)
        using C::f;   // C::f(int), C::f(double), and C::f(char)
        f('h');       // calls C::f(char)
        f(1);         // error: ambiguous: B::f(int) or C::f(int) ?
        void f(int);  // error:
                      // f(int) conflicts with C::f(int) and B::f(int)
}
