Yeah, possibly.  The inet_net_pton.c case is surely because it was that
way in the BIND code we borrowed; perhaps the others are the same story.
I don't object to changing them, since we don't seem to be actively
adopting any new upstream versions; but again I can't get too excited.

I think you got that one backwards.

Perhaps a comment would be in order here?  Specifically something
about providing Assert() so that it can be used in both backend
and frontend code?
