DJGPP is a 32-bit compiler and so only works on a 386 upwards.
Using -O1, -O2, -O3 optimises the program to various levels. -m486
and -mpentium can be used for higher systems.

DJGPP uses inline ASM in the AT&T format. There's a primer at
www.delorie.com/djgpp and while you're there you should download and read
the latest faq. Both of these questions are covered in more detail in the
faq.
