With this morning's (Sep 25 10:18 GMT) code, I get:

cd /usr/src/sys/arch/i386/conf && /usr/src/tools/obj.i386/tools.NetBSD-1.6H-i386/bin/nbconfig  -b /usr/src/obj.i386/sys/arch/i386/compile/GENERIC -s /usr/src/sys GENERIC

    (nil))

Stop.
nbmake: stopped in /usr/obj/.i386/sys/arch/i386/compile/GENERIC

during a ./build.sh -R /release/i386  The build.sh before it was fine (apart
from the usual lack of groff directory while building the tools as this was
the first 1.6H build) and compiling a custom kernel was fine (doesn't have
pcn (AMD PCnet-PCI) enabled).

Bits of interest in mk.conf:
COPTS+=-pipe
UPDATE=1
DESTDIR=/destdir/${MACHINE}
RELEASEDIR=/release/${MACHINE}

Thoughts? (You must all be building GENERIC kernels with no problem..)

Cheers,
