        * objc-act.c (objc_add_dynamic_declaration_for_property): Do not
        search for the @property declation only in the current context,
        but also in inherited properties.  Do not mark the original
        PROPERTY_DECL in the @interface or @protocol with
        PROPERTY_DYNAMIC.
        (check_methods): To check if a method is associated with a
        @dynamic property, search for the property in IMPL_PROPERTY_DECL.
        (check_accessible_methods): Same change.
        * objc-act.h: Updated comment.
