powerpc makes provision (in the ABI) to save the pic reg in nested functions -
so it might have a different/or no problem.

I don't think this is a regression - I think it's been there for(ever/long
time).

(or, just xfailing the testcase on

I guess xfailing is the thing to do for now - maybe give Mike a day or two in
case there's a really easy fix.

 (it's not as simple as just doing that subtraction, as there is no guarantee
that x uses or even saves the PIC reg as things stand) ... 

I am not familiar with how the non-local goto system works, so there's some
reading for me to do before even cooking up a test...
