Well, for the start, you should note that what Microsoft calls 'COFF'
is not the same as what that word meant before they came in to spoil
it. Another case of "embrace and extend", that is. That's one reason
why the GNU BFD library needs a separate backend for 'pe_coff'.

DJ Delorie, the guy who ported GCC to DOS, has one for the variant of
COFF used by that port (DJGPP) on his Web pages:

That's probably not the 100% official story on COFF, either, of
course, but it may be as close as it gets, short of hunting down a
copy of the paper version of the original SVR3 definition, or that
book mentioned by our esteemed moderator.
