I have a completely fresh NetBSD tree as of Mar 24 01:25 UTC.  I just
tried to do a build with it and I get:

/paco/imp/N/sys/arch/hpcmips/vr/vrc4173bcu.c: In function `vrc4173bcu_print':
/paco/imp/N/sys/arch/hpcmips/vr/vrc4173bcu.c:432: `VRIPIFCF_ADDR_DEFAULT' undeclared (first use in this function)

Looks like we need:

To make this compile again.  Since this works on my build box, I've
gone ahead and committed it.  If this isn't right, please let me know.
