No, small amount of ifdef stuff would not work. FreeBSD 8.0 doesn't have
these socket options, you can't bring support for them defining their values.

Even if you manage to compile samba with support for these socket options,
it will fail at runtime, getting EINVAL error from the setsockopt() system
call.
