Recall that in DJGPP you are in protected mode, where return addresses 
are interpreted differently (as offsets from the CS segment base, not as 
seg:off pointers).  That's why the converted code GPFaults.

Invoke Int 19h.  I don't remember whether you need to emit a literal 
instruction "INT 19h" or call via __dpmi_int, but one of these ways 
should work.  (The other one is deliberately blocked by CWSDPMI, for
some obscure reason.)
