Cygwin has /dev/zero, and it fails anyway. I suspect there's some
subtle functionality in /dev/zero that I didn't emulate right. If we
add /dev/zero to djgpp, it needs to be tested well, and it needs to
work *right* or it will cause subtle problems.

It means I don't know. I just saw separate conditionals for those
cases.
