I always wondered about that. In fact, I asked why we don't define it here
a year or so ago. POSIX says in gethostname()
Host names are limited to 255 bytes.
(at least in my recent draft).
So doesn't it make sense for us to define this macro? All users of
MAXHOSTNAMELEN rely on the standard POSIX interface, so even if the Hurd
itself is not limited by this, those programs might rightly rely on this
limit and still claim POSIX compatibility. In fact, it seems if we want to
be POSIX compatible, we must not return hostnames longer than that limit, or?
