If You thought Interix, then You can get installation CD image of it
from M$, burn it to CD and install from CD.
GCC can be used as compiler, but as I remember it is was rather old
version. Anyway I uninstalled it and after that had to reinstall it to
remove some remaining files, as I was not able to delete then from
Windows directly. So I'm sldo think that one should stay away from it.
There is also Cygwin support mentioned in ConceptGCC homepage..., but I
haven't tested it and perhaps I'm not going to do it in near future.

It may be easier to build for example Linux to DJGPP cross-compiler
(long time ago I also suceeded to do so called cross-native build for
DJGPP under Linux, but it was for now ancient GCC version).
As far as I understand from ConceptGCC webpage, its alpha versions seem
to be fork of corresponding GCC versions. If it is so, then the same way
how to build GCC could possibly also be usable for ConceptGCC. As I
wrote earlier, I had problems building GCC-3.4 development versions for
DJGPP. So I could expect the same problems also for ConceptGCC.
