            * match.cc (build_associate_name): Fix whitespace issues.
            (select_type_set_tmp): If the selector is of unknown type, go
            the SELECT TYPE selector to see if this is a function and, if
            the result is available, use its typespec.
            * parse.cc (parse_associate): Again, use the function result if
            the type of the selector result is unknown.
            * trans-stmt.cc (trans_associate_var): The expression has to be
            of type class, for class_target to be true. Convert and fix
            class functions. Pass the fixed expression.
