[Boost-build] Boost serialization API changes

Subject: [Boost-build] Boost serialization API changes
From: Ven Tadipatri (ven.tadipatri_at_[hidden])

We upgraded from Boost 1.38 to Boost 1.45, and our serialization code 
does not appear to work with the new API, specifically the 
BOOST_CLASS_EXPORT.
The specific class used is called ByteDataObjectA, and the issue has to 
do with virtual inheritance, since the compile errors go away if this 
code is placed in the header: (however it still fails at runtime with a 
"pure virtual function" called error

namespace boost{
template<>
  struct is_virtual_base_of<ns:ParentClass, 
testing::dataobjects::ByteDataObjectA>: public mpl::true_ {};
}

namespace boost{
template<>
  struct is_virtual_base_of<ns:GrandParentClass, 
testing::dataobjects::ByteDataObjectA>: public mpl::true_ {};
}

Does anyone have any idea what's going on? Here is how the 
BOOST_CLASS_EXPORT(ByteDataObjectA) macro is resolved in the two 
versions of boost.

Thanks,
Ven

//boost 1.45

namespace boost {
namespace serialization {
template<>
struct guid_defined< ByteDataObjectA > : boost::mpl::true_ {}; \
template<>
inline const char * guid< ByteDataObjectA >(){
     return "ByteDataObjectA";
}
} /* serialization */
}
namespace boost {
     namespace archive {
     namespace detail {
     namespace extra_detail {
     template<>
     struct init_guid< ByteDataObjectA > {
         static guid_initializer< ByteDataObjectA > const & g;
     };
     guid_initializer< ByteDataObjectA > const & init_guid< 
ByteDataObjectA >::g =
         ::boost::serialization::singleton<
             guid_initializer< ByteDataObjectA >
 >::get_mutable_instance().export_guid();
     }}}}

//boost 1.38.0

namespace boost {
     namespace archive {
     namespace detail {
     template<>
     struct init_guid< ByteDataObjectA > {
         static ::boost::archive::detail::guid_initializer< 
ByteDataObjectA > const
& guid_initializer;
     };
     }}}
     ::boost::archive::detail::guid_initializer< ByteDataObjectA > const &
         ::boost::archive::detail::init_guid< ByteDataObjectA 
 >::guid_initializer =
            ::boost::serialization::singleton<
                ::boost::archive::detail::guid_initializer< 
ByteDataObjectA >
 >::get_mutable_instance().export_guid("ByteDataObjectA");
