DJGPP doesn't use/need DOS/4G. It has it's own extender in the stub. I'm not
exactly sure how to do all the stuff you are looking at doing, but I seem to
remember some stuff about that on the list a few weeks ago. Check the
archives, either on dejanews, or www.delorie.com/djgpp/ and search the
archives. Also, to quote Eli Zaretski, check 18.7 in the FAQ.
