--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.  in Objective-C (like Java though different from Java since there is
no implicit inheriting from the Object), all classes inherit from an Object
class.  This Object class contains a few things including but not limited to
the class field.
