[Bug c++/24986] g++ is confused when function is defined inside and outside some namespace and called with '::' prefix

I don't have chapter and verse to justify this, but icc and gcc agree
that they should reject this code
--------------
namespace N {
  class C {};
  void foo(C) {};
}
using namespace N;

void foo(long) {};

void bar() { C c; ::foo(c); };
---------------------
while they both accept the code with ::foo(long) removed:
---------------------
namespace N {
  class C {};
  void foo(C) {};
}
using namespace N;

void bar() { C c; ::foo(c); };
---------------------

One may certainly be tempted to find this confusing.
