* library versions:
* boost 1.39 -> 5
* boost 1.43 -> 7
* boost 1.47 -> 9
*
*
* 1) in boost 1.43 and inferior, class_id_type is always a 16bit value, with no check on the library version
* --> this means all archives with version v <= 7 are written with a 16bit class_id_type
* 2) in boost 1.44 this load_override has disappeared (and thus boost 1.44 is not backward compatible at all !!)
* 3) recent boosts reintroduced load_override with a test on the version :
* - v > 7 : this->detail_common_iarchive::load_override(t, version)
* - v > 6 : 16bit
* - other : 32bit
* --> which is obviously incorrect, see point 1
*
* the fix here decodes class_id_type on 16bit for all v <= 7, which seems to be the correct behaviour ...
