I'm running Boost 1.57.0 using serialization, variant, and boost::blank 
with that variant.

I found that when compiled, serialization complains that blank does not 
contain a serialize method, which is true.

I made a copy of blank.hpp, called it blank.h,  and added

     template< class Archive >
     void serialize(Archive& ar, const unsigned int version) {}

to the body of struct blank.  That made the compiler happy, but is it a 
fix in general?
