On netbsd -current 2.0C sparc64 built a few hours ago, ipnat and ipfilter 
are completely broken.

# /etc/rc.d/ipnat reload
0 entries flushed from NAT list
2:ioctl(add/insert nat rule): Invalid argument
2:ioctl(add/insert nat rule): Invalid argument
2:ioctl(add/insert nat rule): Invalid argument
3:ioctl(add/insert nat rule): Invalid argument

ipfilter can't parse it's config file due to syntax errors.

Any help would be greatly appreciated.
