Actually, it would not *really* be an ABI change, since all such
platforms pass those arguments in registers, and so they would
be zero-extended to 64-bits wide anyhow.
But, the real issue is that POSIX does not have an inet_makeaddr(),
and so defining _POSIX_SOURCE and then using inet_makeaddr() in your
program is incorrect.
