Okay, that's fair and fine. However, any explanation for the linker errors that seem to occur only with unicode versions? Can anyone else try out the demo.cpp example (http://www.boost.org/libs/serialization/example/demo.cpp) with a unicode build, and just change the boost::archive::text_oarchive and boost::archive::text_iarchive to use boost::archive::text_woarchive and boost::archive::text_wiarchive, as well as using wide strings and wide streams? I want to see if anyone else has this issue with 1.33.1? Any chance this might be fixed in 1.34.0?

Note that the library is in two parts. libboost_serialization.. contains code used for all types of archives while libboost_wserialization contains code used only for wide character archives. So applications using wide character archives should link against BOTH libraries.
