Might be a gcc 2.96 weirdness.

                           ^^ This const indicates that the object
                        the method is called on will not be modified
                        (and thereby indicates that the method can be
                        called via a const reference to the object).
                        You can use the mutable modifier for member
                        variables like reference counts and caches
                        which may be modified in a const method.
      ^^^ This const indicates the return value is const
