I wonder whether there is a better way than adding
ifdef values whenever someone reports an issue.

I can't verify but perhaps we also need to check __FreeBSD__
__NetBSD__, __bsdi__, others ?

It would be nice if someone with such a system could
confirm whether CTRL-Z works or not and whether
adding extra ifdef cases fixes it.
