yea!

If this is something mere mortals can reproduce?   If so, I'd enjoy 
trying it out.

I regularly boot netbsd/vax for 11/7xx using the simh simulator.  It's 
easy to set up.  Once it
works I copy my image to a scsi disk and boot on a real live 11/730.

My assumption (perhaps incorrect) is that once pcc is up to speed it 
might well generate better
code for the vax than gcc does, with less cpu and memory.
