Did you try something as simple as reading the FAQ list?  You can get it 
as faq200b.zip from the same place you get DJGPP.  Start with section 
10.1 which answers exactly the question you've asked.  You can also 
search the large indices at the end of the FAQ for items which seem to be 
appropriate for your question.
