[Bug c++/42490] New: using-directive in namespace doesn't work properly

[gcc-bugzilla at contacts dot eelis dot net]

Consider:

  namespace B { struct C {}; }
  namespace A { namespace C { } using namespace B; }
  struct A::C c;

GCC complains:

  error: 'C' in namespace 'A' does not name a type

Not knowing much about the subtleties of name lookup myself, I'm relying on the
following two sources for the code's well-formed-ness:

* Comeau 4.3.10.1 /does/ accept the code.
* The opinion of a particularly well-read regular (litb) on Freenode's C++ IRC
channel.
