For personal use, I compiled a very raw but complete list of every interrupt
called by every function for an older version of DJGPP. DJGPP version 3.4.1
calls about 170 DOS, BIOS, etc. interrupts.  I'll just list the ones that
call 71xx functions below my signature.  If you need to know which ones call
specific functions, just ask in this newsgroup or the other newsgroup you
post DR-DOS announcements too.  Have you contacted Henrik Haftmann or Jason
Hood about 64-bit support in DOSLFN?
