All, 

While cross-building NetBSD-vax under FreeBSD, the below error occurs.
I tracked this back to the mod bringing src/sys/miscfs/kernfs/kernfs_vnops.c
to version 1.102 on May 7 by cl@netbsd.org.  This mod introduces the
particular lines to the file.

It should be noted that the error does not occur building the alpha, amd64, 
hp300, sparc, sparc64 or sgimips ports.
