Oh, I see you were suggesting that the polarity be reversed. Well,
although the #ifndef is a bit ugly, the utility is useless without
Kerberos, so I think I'd rather stick with "enabled by default".
Also, there is KPROGS in head/kerberos5/Makefile, which is a list
of programs that depend on kerberos. gssd isn't in the list, but
maybe it should be? (And that list is used to "dekerberise" them
by setting -DWITHOUT_KERBEROS.)
So, unless others feel strongly about it, I think I'd rather stick
with using WITHOUT_KEREBEROS.
