Correct me if I'm wrong, but you used COFF because "It was the best at
the time (better than a.out), and ELF didn't exist yet".

For some reason, it seems much more popular to target DOS/DJGPP from
GNU/Linux than vice versa. Heck, some GNU/Linux distros (and other
*nix) don't even include GCC (ack!). Very very very annoying.

However, there is a really *old* Binutils 2.9 (before
".intel_syntax"!) for DOS that targets ELF. It's probably easier to
just use something like YASM, though (which targets COFF and ELF, etc.
and can handle NASM or AT&T syntax).
