            Bug ID: 57376
           Summary: Bogus error due to failure of unqualified namespace
                    lookup
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ppluzhnikov at google dot com

Reproduced with current trunk @r199204.

g++ -c t.cc
t.cc:17:25: error: ‘F2’ is neither function nor member function; cannot be
declared friend
     friend Foo *Foo::F2(Woo *);     // error
                         ^
t.cc:17:22: error: expected ‘;’ at end of member declaration
     friend Foo *Foo::F2(Woo *);     // error
                      ^
t.cc:17:29: error: expected ‘)’ before ‘*’ token
     friend Foo *Foo::F2(Woo *);     // error
                             ^

Source appears to be completely kosher and is accepted by Clang and EDG.
Test case:

/// --- cut ---
namespace B
{
  class Woo;
}

struct Foo
{
  Foo* F1(B::Woo *);
  Foo* F2(B::Woo *);
};

namespace B
{
  class Boo:Foo
  {
    friend Foo *Foo::F1(B::Woo *);  // ok
    friend Foo *Foo::F2(Woo *);     // error
  };
}
/// --- cut ---
