This is where I'm going with fwcontrol

[Dieter]

I looked at the changes NetBSD made to fwcontrol.c
with the idea of tweaking FreeBSD's version so it would
compile on both OSes.  Below is a patch that might be enough.
They made more changes than this.  Some are clearly not essential
(whitespace, putting the usage message into alphabetical order, ...),
some I'm not sure about so I left them out for now.  The full set
of changes they did can be viewed by diffing FreeBSD cvs 1.23
with NetBSD cvs 1.7.  It still compiles fine on FreeBSD 7.0 amd64,
(and the getprogname() thing works) I haven't tried NetBSD yet.
