[Bug c++/37804] New: Nested type leaks to global scope

["therealfroggey at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

GCC versions used:
gcc version 4.1.2
gcc version 4.4.0 20081011 (experimental) (GCC) svn revision 141055
Command line used: g++ -Wall -Wextra bug.cc

The following code should fail to compile as Internal_B is a private class
within class A.
Both tested version of gcc successfully compile it with no warnings.

------------

template <typename T>
class A
{
private:
  class Internal_A
  {
    friend class Internal_B;
  };
  class Internal_B { };
  Internal_A a;
};

A<int> a;

Internal_B some_function();
