I don't know how to use _XOPEN_VERSION or _POSIX_VERSION to check for

I suppose we could also define _NETBSD_SOURCE manually, which is
basically what we do on GNU/Linux. G++ predefines _GNU_SOURCE so that
glibc gives us all declarations, but I want to move away from that and
stop polluting the global namespace with every GNU extension.
Maybe defining _NETBSD_SOURCE for versions older than 7.x is the right
