        * c-parser.c (c_parser_objc_at_property_declaration): Recognize
        RID_ASSIGN, RID_COPY, RID_RETAIN, RID_READWRITE and RID_NONATOMIC.
        Do not use objc_set_property_attr, but use local variables
        instead.  Detect repeated usage of setter, getter and ivar
        attributes.  Improved error processing when a setter name does not
        end in ':'.  Do not check for CPP_CLOSE_PAREN after we determined
        that the token is a keyword.  Updated call to
        objc_add_property_declaration.

        Code rewritten to be much more robust in recovering from syntax
        errors.  Added comments.

        (c_parser_external_declaration): Updated calls to

        * parser.c (cp_parser_objc_property_decl): Renamed to
        cp_parser_objc_struct_declaration.  Return the parsed trees
        instead of calling objc_add_property_variable directly.  Detect
        missing or invalid declspecs.  Implemented attributes.  Do not eat
        the ';' at the end.  Exit loop whenever a non-comma is parsed, not
        just EOF.
        (cp_parser_objc_at_property): Renamed to
        cp_parser_objc_at_property_declaration.  Updated calls to
        objc_add_property_variable, now objc_add_property_declaration, and
        to cp_parser_objc_property_decl, now
        cp_parser_objc_struct_declaration.  Rewritten all code to be more
        robust in dealing with syntax errors, and almost identical to the
        one in c_parser_objc_at_property_declaration.
        (cp_parser_objc_property_attrlist): Removed.

        property declaration is found outside an interface or
        implementation context.
