When I encountered this error message, I found I was making function
calls across object files without using the FAR keyword.  If you're
able to make function calls within the same object file, but not
across different object files, then you probably have the same
problem.  You should should declare the function as FAR in both its
definition object file and in the object file where it is being used.

If you need more help with multiple-segment small-model applications,
try the Petzold book; I've found it an indispensable reference for
such problems.

By the way, I found the MSC manual was no help on this problem; i.e.
the manual says:

L2003    intersegment self-relative fixup
         An intersegment self-relative fixup is not allowed.

Maybe people at Microsoft find these kinds of error messages helpful,
but I sure don't :-).

Hope this helps...
