Its weird that this comes up since i build tested it for amd64 (native) and
i386 (cross om amd64) with success here on NetBSD 6.0_BETA2. I already patched
this on the 2nd:

cvs rdiff -u -r1.81 -r1.82 src/sys/arch/usermode/usermode/thunk.c

I added the stdarg.h reference just in case and i double checked and build
tools+build+release and it still compiles here. This is very odd!

I'll comment out the i386 and amd64 usermode kernel builds for now so not to
frustrate others but i have no idea why this happends... What is different for
the autobuild system that it fails where as it here crossbuilds fine with
build.sh?

With regards,
