Status:	O

To put my own two cents in, I have ported a *large* set of DOS programs to
DJGPP, and been very happy with the results. I moved them from Microsoft
Quick C with minimal difficulty.

One notable problem, of course, was porting a large quantity of existing
graphics code intended for Microsoft C. I created a .h file full of macros
and whatnot to translate the calls rather than putting a layer of
expensive function calls in between. However, I had the benefit of a beta
version of a graphics library (is the author out there? I can't find your
email address!!! foolish on my part not to keep a copy of course) taht
supports 16-color modes and user-defined clipping regions in C rather than
only C++. Without that, I would have had a great deal of difficulty accom-
plishing the port. I think 16-color modes and clipping boxes are sensible
additions that should be made in the next version of the standard GR
library.
