            Bug ID: 60860
           Summary: Friend function declaration incorrectly hides function
                    in outer namespace
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dibeas at ieee dot org

The following valid code fails to compile:

void f( int );
namespace N {
    struct A
    {
       friend void f(int);
       friend void f(double);
    };
    void g() {
        f(0);
    }
}

The problem goes away if any of the two friend declarations is commented out.
