     The iinnssqquuee() and rreemmqquuee() functions manipulate queues built from doubly
     linked lists.  Each element in the queue must in the form of ``struct
     qelem''. The function iinnssqquuee() inserts _e_l_e_m in a queue immediately after
     _p_r_e_d; rreemmqquuee() removes an entry _e_l_e_m from a queue.
