I did ask about this in the previous e-mail.  I thought non-primitive
types were, by default, versioned, i.e. if no BOOST_CLASS_VERSION is
specified, they have a version of 0.  Is this not the case?

Anyway, the code I posted still gives odd results if I set
BOOST_CLASS_VERSION(Test_c, 0).  Anything but 0 works, but zero gives
the effects described previously, a 3 on the way back in, which is your
archive version, not the class version.

Again, specifying no version works for text archives (haven't checked
binary) but not for XML.

Thanks
