What operating system? Obviously not Linux...

Good point. I've fixed those.

That's also going to fail in the same way if EAGAIN isn't defined. I've
split the checks onto two lines which should work in all cases.

That sounds like a Cell-specific case all right. Would something like this:

#undef EAGAIN

in setup.h solve the problem?
