OK, I've committed the patch.  I found that it collided with this one 
from Jakub:

http://gcc.gnu.org/ml/gcc-patches/2007-08/msg01641.html

but made the obvious correction, and verified that it still builds and 
that CSiBE results on MIPS do not regress from my previous version. 
I've attached the final version of the patch.
