Comment (by ramey):

 note that the current code in trunk and release looks like:

 {{{
     void load_override(version_type & t, int version){
         library_version_type lvt = this->get_library_version();
         if(boost::archive::library_version_type(7) < lvt){
             this->detail_common_iarchive::load_override(t, version);
         }
         else
         if(boost::archive::library_version_type(6) < lvt){
             uint_least8_t x=0;
             * this->This() >> x;
             t = boost::archive::version_type(x);
         }
         else
         if(boost::archive::library_version_type(5) < lvt){
             uint_least16_t x=0;
             * this->This() >> x;
             t = boost::archive::version_type(x);
         }
         else
         if(boost::archive::library_version_type(2) < lvt){
             // upto 255 versions
             unsigned char x=0;
             * this->This() >> x;
             t = version_type(x);
         }
         else{
             unsigned int x=0;
             * this->This() >> x;
             t = boost::archive::version_type(x);
         }
     }
 }}}

 Doesn't this do the job for you?
