You cannot use all those nifty libraries on Unix, because they aren't
binary-compatible with any OS other than DOS.  You will have to port them 
to Unix on the source level, and if you do that, you can just compile 
your program with GCC on Unix.

The compiler in DJGPP is GCC, period.  It is configured to produce 32-bit 
code on Intel x86 architecture, but other than that, it doesn't do 
anything that GCC on Unix doesn't.
