My DJGPP programs have all compiled very nicely, OOTB. DJGPP is quite
complete ;)

The overlap is nearly 100% - there are a lot people porting all kinds of
stuff to DJGPP - very nice :)
The reason I want to keep using DJGPP is that it is a fine compiler, as I'm
sure CygWin is too (because it's nearly the same compiler) and that most of
the time, all I need is a DOS binary (which suits my purposes better than
Windoze binaries, console or otherwise).
Point is: I know and like DJGPP, and use it extensively. There are some
things DOS can't do that Windows can (multitasking) so I will need CygWin
for some stuff, but I'll be using DJGPP for most of my work (and porting to
CygWin when Windoze binaries are desired).

That's kinda what I had planned, though the Bash shell seems to do the job
nicely as is..

Yes, this seems to work rather nicely.

Thanx for the responses!

Greetz!
