No, I don't think so.  The representation has "always" (i.e., for as
long as I can remember) been that the global namespace was represented
as NULL_TREE, while other namespaces are represented by NAMESPACE_DECL.
  (One could argue that's a silly non-uniformity, but that's how it's
always been.)

If we're setting TYPE_CONTEXT to global_namespace, I think that's a C++
front end bug.  Which type is getting set up like that?
