[Bug c++/15821] New: Duplicate namespace alias within namespace rejected

[stephan dot bergmann at sun dot com]

The code

  namespace a {}
  namespace b {
    namespace c = a;
    namespace c = a;
  }

fails for 3.4.0 ("declaration of 'namespace c = a;' conflicts with previous
declaration 'namespace c = a;'"), but works for 3.3.3.  The simpler code

  namespace a {}
  namespace c = a;
  namespace c = a;

works for both 3.4.0 and 3.3.3.
