Using built-in specs.
Target: x86_64-unknown-linux-gnu
Configured with: ../gcc-4.0.0-20050410/configure --enable-languages=c,c++
--prefix=/dept/rnd/vendor/gcc-4.0.0-20050410-amd64 --enable-threads

> cat bug.C 
namespace A { struct Foo {}; }
namespace B {
struct Foo : public A::Foo
{
  public:
    struct Bar {
        friend struct Foo;
      protected:
        int v;
    };
    Bar bar;
    int foo () { return bar.v; }
};
}

I believe that friend struct Foo should refer to B::Foo
but it seems to instead refer to A::Foo.  This code compiles
correctly on gcc-3.4.1.

I don't remember the rules for friend but I do that 4.0.0 has become closer to what the standard says.

The unqualified name Foo is looked up within the class hierarchy, and finds 
the name of the base class.
