My mail bounced, too.

     You might have made a typo, so I just wanted to be sure that you
knew the correct order for the parameters.

  long    rectread(Screencoord x1, Screencoord y1,
                   Screencoord x2, Screencoord y2, Colorindex parray[]);
  long    lrectread(Screencoord x1, Screencoord y1,
                    Screencoord x2, Screencoord y2, unsigned long parray[]);

  void    rectwrite(Screencoord x1, Screencoord y1,
                    Screencoord x2, Screencoord y2, Colorindex parray[]);
  void    lrectwrite(Screencoord x1, Screencoord y1,
                     Screencoord x2, Screencoord y2, unsigned long parray[]);

You've got (x1,x2,y1,y2) not (x1,y1,x2,y2).  While this is different from,
say, ortho2(), viewport(), and scrmask(),  it is the same as rect().
