There should be no problem with this from the compiler point of view;
which doesn't mean that it isn't difficult. Since both win32 and linux
support dynamical loading of libraries, it should be possile to do this
in a platform independent way.

It should be fixed now. at least the test programs we got from you, and our
own, seem to work correctly. Get the latest version from CVS to test.
