My code doesn't modify either of these functions, so
I'm not causing the regression.

Also, I can't reproduce this error on the current head of 
Ingo's tree:
http://people.redhat.com/mingo/tip.git/readme.txt

I do `make allnoconfig; make all` without errors, apply
my patch, and do `make all` again without errors.
