Read chapters 10, 17, and 18 of the DJGPP Frequently Asked Questions
list, available from SimTel as v2/faq210b.zip or online at
http://www.delorie.com/djgpp/v2faq/.  Specifically, chapter 17.8 tells
you what to do with those Borland-style pseudoregisters.

FYI, that code is written for Borland-style real mode compilers, and
will probably require extensive modifications to work with DJGPP!
