_If_ I read Gerard correctly, this is not the problem. The problem
_appears_ to be that DEC created some additional VAX-only RTL and so
far Gerard has been able to survive by translating this additional
VAX-only RTL to more recent architectures.

_If_ I understand correctly, then it appears there is no native version
of this additional RTL (whatever it is) available on x86-64.

Gerard needs to give us exact information about this RTL and the
functionality it provides so we can suggest alternatives.
