With the patches I committed today, ECL can even compile such
structures. The only problem, but this is a completely unrelated one, is
that EQ of the externalized data is not always preserved when using
COMPILE-FILE (It is when using COMPILE because constants are never
written to the C file)

After some testing and feedback from people out there, I think the issue
of externalization of constants in ECL is mostly solved. In this sense,
I think this implementation is better than CMUCL's because we can dump
constants with circular references _and_ non-printable objects.
