    This sounds like an appropriate place to mention some of the benefits
of the Topspeed C compiler vs. Microsoft or Turbo C.  The topspeed compiler
allows you to specify just about anything having to do with calling
conventions on the fly - segment names, parameter passing in registers,
stack frame layout, inline function expansion, and register preservation.
And you can recompile the run-time libraries to use whatever calling
conventions you like.  So, you can generally use most 3rd party libraries, 
regardless of what compiler they were generated with, if you know its
calling conventions.  You just add some compiler directives to the header
files.
