Part of the orginal patch was not applied.  It was only applied to the trunk as
it was also part of Roger's patch.

What target milestone is this bug? If it is meant to be 4.2.0, shouldn't the
missing section of the original patch be applied to gcc 4.2 branch?

Is this slated to be fixed before 4.2.0 comes out?  Also, I think this can be
marked as confirmed.

Andrew, can you identify whatever portion of this patch has not yet been
applied to 4.2?

This portion which was part of my original submitial (though Roger found it
when he was fixing a different issue):
2006-11-10  Roger Sayle  <roger@eyesopen.com>

        * expmed.c (make_tree): Use the correct type, i.e. the inner
        type, when constructing the individual elements of a CONST_VECTOR.

Let me attach this portion of the patch.
