Right. As I've said in earlier threads, we're mostly just making the
YYLTYPE representation closer to that of the default, which has the
following fields:  first_line, first_column, last_line and
last_column. I just want two fields. I think we've already paid most
of the price that this imposes, by using the @n feature in the first
place. Certainly, I couldn't isolate any additional overhead.
