Please see http://lists.boost.org/Archives/boost/2007/11/130828.php and 
http://lists.boost.org/Archives/boost/2007/11/130831.php.

My machine is tied up at present: can you double check that moving 
codecvt_null.cpp to boost_wserialization breaks dll building of 
Serialization with msvc? (I'm 99% sure it will do if the header is included 
by any of the sources).

Then try Robert's suggestion of changing the export declaration to 
BOOST_WARCHIVE_DECL and see if it works as expected: you'll probably need to 
run the serialization regression tests with both msvc and mingw to be sure, 
which may take a while :-(

HTH, John.
