No, I was just making a point. It's a silly app, CFunge, a "fast"
Befunge98 interpreter written in C99/POSIX. The point was that he
brags about POSIX yet uses things like mmap() which aren't in older
POSIX standards, hence DJGPP is out by default. Basically, he uses
mmap() for simplicity and efficiency, I think. He's definitely NOT
interested in DJGPP, though, so even if I was able to patch it, he
won't integrate changes. (There are other B98 interpreters, including
original / official "fbbi", which DJGPP happily accepts. I just
thought having one more couldn't hurt, heh.)
