--- Comment #1 from Ismail Pazarbasi <ismail.pazarbasi at gmail.com> ---
Clang handles this case correctly.

class_2 injected class name will be inherited by class_1 as well, but it will
be a private member in class_1 (and, hence, in class_0). In the declaration of
var_4, class_2 refers to this privately inherited injected class name. Class
scope will be looked up first, and a name will be found, but it will not be
accessible. 

Use fully qualified name for class_2 to refer to class name in global
namespace.

struct class_0 : private class_1 {
  struct ::class_2 var_4; // OK
};

The error message, however, could be improved. In this particular case, class_2
name is actually not a private member of class_2, but it's a private member in
class_1 because class_1 privately inherits names from class_2. Injected class
names are public members of classes.
