 I've narrowed the problem down to the -msse2 that is in the version
 of Makefile.inc1 that I have.  I notice that this flag was removed
 in Makefile.inc1 v1.499.2.18.  Some manual experimenting with the
 CFLAGS implied by that Makefile suggests that the problem goes away
 with the newer Makefile.inc1.
 
 I will upgrade world and retry.
