It doesn't exist in OpenBSD (and likely most BSD's), either. Certainly not
with OpenBSD 4.0.

In my personal compat library, alternatives for which I'll alias ENOTSUP are
EOPNOTSUPP (BSD), or EINVAL (everywhere).

ENOTSUP is specified by SUSv3, though. So it's not a bad idea to use it, it
just hasn't caught on widely.
