Hey Robert,

first off, thanks for the work on the serialization library, it looks 
really good so far.

sorry for not including this info in my original post.

> what compiler are you running?

Microsoft Visual Studio .NET 2003
boost succesfully built using boost.jam

> which version of boost are you running?

1_33_0

> do the tests/examples run on your system?

yes.

> what do the warnings say?

warning C4541: 'dynamic_cast' used on polymorphic type 
'boost::archive::detail::basic_oarchive' with /GR-; unpredictable 
behavior may result

(see full warning below.)

this is compiling the following code:

std::stringstream ss;
boost::archive::binary_oarchive oa(ss);  //also tried with text_oarchive
std::vector<int> myvec;
myvec.push_back(12);
const std::vector<int>& ref = myvec;    //seem to require a reference.
oa << ref;

> I would think what you've done below should work.

thanks for the realitycheck,

   Lucas
