I agree this is a correct change, interesting that it was missed before.  You'd 
expect some ICE issues from that mistake.  Perhaps there were and I didn't 
realize the cause; the PDP11 test run is not yet fully clean.

I've hacked together a primitive newlib based "bare metal" execution test setup 
that uses SIMH, but it's not a particularly clean setup.  And it hasn't been 
posted, I hope to be able to do that at some point.

Thanks for the fix.
