Much thanks to all....

My impressions of this email thread [subject you your corrections], 
are 1] Compiling from DJGPP to a UNIX/Linux executable is difficult 
and only for the expert user, [which I am not] and 2] there is no IDE 
for DJGPP with a GUI, that will let one write, compile and debug 
code, other than RHIDE.

This leads to a separate question.... What are the functions and 
features in DJGPP which are not compatible with Unix/Linux?

Again, thank you very much.
