Aka
(if (if (< #x7FFF (abs (- sequence1 sequence2)))
;; Overflowed
(< sequence1 sequence2)
(> sequence1 sequence2))
1 -1))))
Or even
(if (funcall (if (< #x7FFF (abs (- sequence1 sequence2))) #'< #'>)
sequence1 sequence2)
1 -1))))

Thanks, Stefan. I've made the function return the difference of
sequence numbers instead, which should be cleaner.
