This is a known bug and is already fixed in the newest versions in the
CVS.

The MSVC workspaces are quite old. So they miss out a few files. As
these files aren't compiled their functions aren't availbe at linking.

So you'd just need to add the missing files to the correct projects
(IIRC only SSG is affected).
