Hi Robert,

The EXPORT macros were initially inside a namespace,
interesting that it compiled and linked with gcc.  

After fixing this I still have the same problem with
Microsofts compiler.  It complains about the same thing as
I state below.  Is there some include file that I may be
missing?  I can send you some code if that helps.

Also where is the best place to call these macros?  At the
moment they are at the top in the appropriate .cpp files.

Thanks,
-K
