The version where I reverted the change is 1.6.

There is apparently a code problem somehow, since we know that AIX/PPC 
at least orders things differently on those 2 tests.

I have looked at the new code and can't see any obvious reason for 
ordering differences.

Maybe we need to try to stress test the comparison routines a bit to 
make sure they really are deterministic.

We will deal with that one in due course.
