Re: [boost] [1.35] Serialization shared_ptr_132headers cause compilation error with g++ 4.1.0

Any existing header order dependency would be news to me and I would be 
interested in seeing it fixed.

Given that you've expended the effort to find the problem in a specific 
case, do you have any suggestion about what change should be made?
