Please, *please*, PLEASE read the DJGPP FAQ list!  The above question is 
answered there in so many words, in section 17.1.  This issue is too 
large and complex to answer here, so please read the docs, including the 
GCC Info files which explain how to use the inline assembly.

This is also explained in the FAQ, section 10.6.

The latest version of the DJGPP FAQ list is available as faq102.zip from 
the same place you get DJGPP.
