My copy of it does now. 

build.sh seems to be trundling through things, so all I have to do now is find 
my stash of blank CDRs. I finally have my StarMax 3000/180 going, and I want 
to run a real OS on it.

I'm afraid that I don't have the time or energy to enter into the debate on 
whether or not alloca is suitable for use. I have far too many machines that 
need NetBSD installed on them.

Cheers,
Lloyd
