All this looks like a refinement of the auto-liink stuff which we've had for MSVC and Borland for years.
As John has already mentioned, this is a pure symbol visibility issue.
So it's OK. I would like to see this stuff checked into the release branch before I make these changes in the serialization library.
Just checked again, all patches are already merged to release. I merged Boost.Test myself ;-)) I still have to find some time to address the other libraries...
With the last change I made in the serialization library, the only missing symbols are void_upcast and void_downcast. the *.cpp files which defiine these functions to indeed define BOOST_SERIALIZATION_SOURCE so these symbols should be exported. I'm trying go figure out why this is not happening. Including define BOOST_SERIALIZATION_SOURCE in a different file can't be the solution - the fact that it seems to work can only be a hint as to what the problem is. Still thanks for the insight.
If you got gcc-4.x around, the easiest solution would be to apply the visibility patch and then compile with "<cxxflags>>-fvisibility=hidden". You should then get the same linker errors as mingw.
