A fix for this is on 'develop' but did not get into Boost 1.57.

If you want to eliminate it locally, look for 
BOOST_HAS_PRAGMA_DETECT_MISMATCH in 
boost/libs/config/include/boost/config/compiler/visualc.hpp and change 
the line above it to read:

#if _MSC_VER >= 1600  // 160X == VC++ 10.0

After saving, rerun 'b2 headers' from the installation directory.
