[Bug c++/16468] New: using-declaration of namespace name

["boris at kolpackov dot net" <gcc-bugzilla at gcc dot gnu dot org>]

$ cat >test.cxx
namespace n
{
  namespace m
  {
  }
}

using n::m;

$ g++ --version
g++ (GCC) 3.4.0

$ g++ -c test.cxx
test.cxx:8: error: namespace `n::m' not allowed in using-declaration

I have searched through the standard and did not find any restrictions on the
type of name in using-declaration.
