>Description:
Compile this:

struct A {
  enum X { Y };
};

enum A::X z = A::Y;

GDB will print out the type of z as "enum X".

Compile this:
namespace NS
{
  struct B { int q; };
  B qq;
  int f() { return 0; }
};

struct A {
  enum X { Y };
};

enum A::X z = A::Y;

Now GDB will print out the type of z as 'enum A::X'.  If your headers happen to trigger this, it causes a failure in classes.exp.

This has to do with handling of processing_has_namespace_info.  I think we need to approach whether to trust scope information differently.  I don't have time to debug it further right now.
