I believe that #include &lt;boost/serialization/shared_ptr.hpp&gt; should
support both boost::shared_ptr as well as std::shared_ptr.  Check
test_shared_ptr.  I believe this is illustrated here.

Note that this is an unusual case since boost shared_ptr serialization
is supported in the serialization library rather than the boost smart_ptr
library so the above advice is not universally applicable.
