Has Matt done an assignment?  I note he has committed several things to 
the gnu tools tree.

I'll look at this one, I suspect it might mean picking through the 
entrials that are the gcc/arm back-end to find all the places it might 
affect ;-{

* (asm sources) Ensure these preserve 8-byte stack alignment if not tail 

* (gcc) packed enums (should be trivial to implement in the compiler, but 
I've heard rumours it might break openssh).
