        * objc-act.c (objc_add_synthesize_declaration_for_property):
        Iterate over IMPL_PROPERTY_DECL, not CLASS_PROPERTY_DECL, when
        checking for an existing @synthesize or @dynamic declaration.
        Search for an inherited @property declaration if none is found in
        the local interface.  If the required instance variable does not
        exist, return instead of trying to continue to prevent a compiler
        crash later.  Check that the instance variable is not already
        being used by another @synthesize.
        (objc_add_dynamic_declaration_for_property): Iterate over
        IMPL_PROPERTY_DECL, not CLASS_PROPERTY_DECL, when checking for an
        existing @synthesize or @dynamic declaration.
        (objc_synthesize_getter): Search for the getter declaration in
        protocols and superclasses as well.
        (objc_synthesize_setter): Search for the setter declaration in
        protocols and superclasses as well.
