 Hi,

 I would appreciate some reference to the standards in
 boost/serialization/singleton.hpp. Specifically why this is supposed to
 work on "working compilers":

     BOOST_DLLEXPORT static T & instance;
     // include this to provoke instantiation at pre-execution time
     static void use(T const &) {}
     static T & get_instance(){
         static T t;
         // refer to instance, causing it to be instantiated (and
         // initialized at startup on working compilers)
         use(instance);
         return t;
     }

 Thanks!
