You are using the GCC inline assembly facility without reading about it 
first.  It is *very* different in syntax from what you are obviously used 
to with other DOS-based compilers.  Please read section 17.1 of the DJGPP 
FAQ list (available as v2/faq202b.zip from the same place you get DJGPP), 
it explains some basic issues and points you to sources of more detailed 
information.
