   Ah! I did not think about it that way. That works.
   I'm not overly enthusisatic about using vararg macros though. The
problem is it's hard to make them work across compilers (not that Wine's
code is extremely protable to start with but we try still).

   Oh well, we'll duplicate the definitions. It's not that bad.

   Thanks a lot for your help!
