I am seeing a bootstrap failure on AIX (powerpc-ibm-aix4.3.3.0).
I last bootstrapped earlier this week and Aldy bootstrapped with his
Altivec changes, so he doesn't believe that is the cause. We don't know
exactly which recent changes could have caused this. I tried reverting
the df.c/h changes and that did not have any effect.
