I think you should report these to Sun.  

I'm really surprised you only see two errors.  The last time I tried
to get Boost libraries to work with a released Sun compiler (a couple
of months ago), I was able to make Sun pass around 50% of all boost
regression tests.  It's ability to handle standard C++ constructs was
so bad that I don't think there's any hope of getting it to work with
Boost.Python.

I've heard reports that their pre-release compiler implements a lot of
bug fixes needed to work with Boost.  Is that what you're using?  If
so, I still don't have access to this compiler so it's unlikely I'll
be able to come up with a workaround for its bugs.  If you come up
with something that makes it work, pleas submit a patch!
