I'm not sure that's wise.  I'd rather special-case DJGPP and similar
systems.  I don't see the problem with that from DJGPP's point of
view.

SunOS (or some other BSD-ish system(s)), I think, at least in some
circumstances.  I think there are comments about that somewhwre in the
g77 configuration stuff.

It would if a configure test running a program indicated it wasn't
needed but it really was when you come to use a different filesystem.

I'm quite surprised, but I'm glad if it works so well.  I certainly
failed with the only autoconfed (non-GNU) program I can remember
trying under DJGPP.  I'd expect various things to break because of
filenames, if nothing else.
