What is DataEase?  Does it come as an object file library?  If so,
your problem is much more serious than what you seem to think: linking
DJGPP with object files produced by other compilers usually doesn't
work.  See section 17.5 of the DJGPP FAQ for more details.

To get functions that use Pascal calling convention, use the `stdcall'
attribute, it's described in the GCC docs.  As for `far', simply
define it away; section 17.7 of the FAQ shows how.

But the fact that DataEase wants `far' probably means that it uses
either real-mode code or 16-bit protected-mode code.  Both are
incompatible with DJGPP.
