How bizarre.  I remember being shocked that it had built so quickly - I
actually assumed that it hadn't built correctly at first, but it had.  I
suppose it could have been because I was able to use objasm to assemble it,
and I'm assume that you're not using it.

Idle curiosity really: how long do native builds take nowadays?  It used to
be 45-50 minutes on a SrongARM Risc PC, IIRC?

It's a shame.  Looks like that work was lost then :-(
