The fix has been committed.

Good catch!

Thanks.

Pardon me, but I was mistaken here. BEFORE_DEPEND are not a problem, it 
was just that the output on console was confusing.

This is enough. I'll commit right away.

.ORDER: ${_MACHINE_FWD}/include/machine ${_FWDHDRS} ${_LHDRS} 
${BEFORE_DEPEND} \
         genassym.o

Only fixes the BEFORE_DEPEND stuff, but not genassym.o.

genassym.o: $S/machine/$P/$M/genassym.c forwarding-headers

Fixes the latter. I'll try some more things later on, but this appears 
to work. I'll see what the minimum required is (maybe just the 
additional dependency on the forwarding-headers target for genassym.o is 
enough), and then commit that if no objections arise.

It seems the BEFORE_DEPEND stuff is done too soon. Perhaps the .ORDER in 
kern.fwd.mk should read something like this:

.ORDER: ${_MACHINE_FWD}/include/machine ${_FWDHDRS} assym.s ${_LHDRS}

Would that be possible?

Alas, it doesn't. The exact error is:

Is this perhaps done before the fwd phase, or part of it?

I hope kern.fwd.mk rev 1.6 fixes your problem.

Cheers.

It appears a `make buildkernel` is not safe for more than one parallel 
make. The fast scrolling output didn't make things very clear, but I 
highly suspect there is no proper .ORDER -ing of the mkdep phase. Where 
it normally is busy for a couple of seconds doing that, it now rushes 
right along. I'm not enough of a Makefile guru to fix that though, I fear.
