Yo Hal!

Thanks, a good list.  I recognize most of those are having been around a
long time (daemon(), strlcat(), etc..  The only one that worries me is
the llabs() one, but I'll work on them all after FreeBSD builds.  AKAIK,
FreeBSD is the only one to error out now.

I have a FreeBSD VM up now, but I am hopelessly clueless.  Progress will
be very slow...  Network not even up yet.
