Bug or Bogus?

[Thomas Weise <tw4 at irz301 dot inf dot tu-dresden dot de>]

I'm wondering if the following snipped of code is just wrong:

class foo
{
  public:
   static int f();
   // bar is just a friend of static member foo::f(), what has been
   // already declared
   class bar {
     friend int foo::f();
   };
};
 
int main()
{
   return 0;
}
