We have both of those in our cluster and they find bugs.  And IRIX 6.5.19
supports IPv6.

So putting a change into the tree that doesn't compile on these machines
is kind of a bummer for us.  If there is a way to ifdef it out we can
change our build process to do so.

I personally could care less about IPv6, I believe that NAT solves the
address problem and the world will come to that realization and we'll
claw back all those class A blocks but whatever.   I just need a tcl
that works w/ IPv4 on those old platforms.
