I think my last post acknowledged this situation.  There is code
in the trunk which traps with BOOST_STATIC_WARNING
attempts to serialize these types through a pointer but currently
it's disabled. I'm going to look at this more carefully.

This is one of a few circumstances where it would be convienent
to temporarily override serialization traits with a wrapper.
Unfortunately, no one has figured out how to do that yet.
