Could you upload it somewhere?  Sounds interesting...

Do they have to be separate executables?  If not, you can try the tasks
library which comes with libgrx.  If so, DOS's monotasking (unitasking?)
will make the project a rather difficult one, and it is not, AFAIK, planned
to be added to DJGPP2 (although it might be nice to figure out a way to
implement it, figure out a way to share libraries, and combine the
two--probably incredibly difficult, though).

And you're using C++!?  My experience has been that even stripped, optimized
C++ executables using only -liostream are still at least 100K with DJGPP but
only about 30K with TC++.  YMMV, of course.

>Another question : What is the number of last version of GNU for PC ?
DJGPP 1.12 includes GCC 2.6.0.

One more general suggestion--is Linux an option for you?  If so, most of this
will become a non-issue.  At any rate, good luck!
