>Description:
I've activated the support for Packet Filter in my kernel configuration file (see below) and it breaks the kernel compilation, returning the following error :

Stop.

>How-To-Repeat:
Enabling Packet Filter support in the configuration file with the latest kernel of NetBSD 3.0.

You can download the configuration file from this URL :
        http://thetemplar.free.fr/MOIMOI

>Fix:
 The only way I know, at the moment, is to desactivate the support of Packet Filter in the latest NetBSD 3.0 kernel if I use the configuration given before.
