[boost] [serialization] export.hpp (or type_info_implementation.hpp) is NOT self-contained and causes compile error

The following code should compile: 

#include <boost/serialization/export.hpp> 

class A { }; 
BOOST_CLASS_EXPORT( A ); 

instead I got: 
error C2027: use of undefined type
'boost::serialization::extended_type_info_impl<T>' 1> with 1> [ 1> T=A 1> ] 

Which file needs to be included to make this compile?

Regards,
