        * objc-act.c (lookup_property): When checking categories, also
        check the protocols attached to each.
        (objc_add_property_declaration): Determine the
        PROPERTY_SETTER_NAME and PROPERTY_GETTER_NAME here.  Tidied up
        error message.  Search for an existing property declaration with
        the same name which would be inherited from the class hiearchy,
        and produce an error if it has incompatible attributes.
        (check_methods): Changed second parameter.  If the method is a
        getter or setter for a property, do not warn if it is inherited as
        opposed to implemented directly in the class.
        (check_protocol): Updated calls to check_methods.
        (finish_class): Do not determine the PROPERTY_SETTER_NAME and

        that a property does not have a DECL_INITIAL.  Validate the
        property assign semantics and emit appropriate errors and

        for the @synthesize.  Always use PROPERTY_IVAR_NAME as it is
        instead of trying to guess what it should be.  Removed use of

        instead of aborting, if the setter prototype does not have the
        expected argument.
        (objc_add_synthesize_declaration_for_property): New.
        (objc_add_synthesize_declaration): Removed ATTRIBUTE_UNUSED from

        (finish_class): Added explicit switch cases for
        CLASS_INTERFACE_TYPE, CATEGORY_INTERFACE_TYPE and
        PROTOCOL_INTERFACE_TYPE.  Added a default switch case which is
        gcc_unreachable.  Rewritten the processing of properties, in
        particular to not synthesize prototypes for getters and setters if
        they already exist and to install the getter and setter names into
        PROPERTY_GETTER_NAME and PROPERTY_SETTER_NAME.  Do not generate
        warnings about setter, getter and ivar property attributes.
        (objc_lookup_ivar): Removed support for properties.
        (objc_gimplify_property_ref): New.

        Be smarter in demangling method names so that at least for methods
        with no arguments we are able to almost always demangle '_' correctly.
