I just looked at this, and I get 198 serialization lib test failures in 
C++03 mode currently :(

The issue is that your tests are using Boost.Math, specifically 
float_distance, and this is now C++11 and later.  It's used fairly 
ubiquitously in your tests as well.

Given that we've signaled this change for over a year now, how do we 
handle this?

Best, John.
