IMHO, usage of any serialization API should never, ever introduce 
problems across different compilers. That's the whole point of 
serialization, I'd say :-)

Having used boost::serialization once, I would say your code will work 
without problems across different compilers if it works on one of them. 
(The serialization API knows nothing of the Implementation details of 
the STL collections, it does its work just with the std interfaces.)
