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.)
