I originally built suidperl, but the last time I rebuilt it I just
left it out.
Curious thought...could NetBSD use the fdesc fs to have more secure
setuid scripts like SVR4 does?
Ala, kernel runs setuid script. If the /dev/fd is available it puts
the opens script on fd 3 (or whatever is available), and then passes in
/dev/fd/3 as the argument to the script. If /dev/fd isn't available it
does it the old way.

I fixed this. I don't remember what I did exactly (I just moved my modem
to a different com dev and I can't login back to home), but I think
it involved just adding the proper typecast (if you look at what its doing
it's correct, the problem is older versus newer types/protos and Classic
versus ANSI C).
I also ended up just manually editing all the AF_LOCAL's to AF_PLOCAL or
something like that.
