This code was written for some other compiler, probably Borland. Also, as
someone else said, SCREEN_HEIGHT and SCREEN_WIDTH are misdefined. `far' does
not work for DJGPP; you will have to use farptr functions or the Fat DS hack
instead. Read FAQ sections 18.4 and 18.6, and the libc docs for `_far*' and
`movedata'.
