Good to know. Miguel, it seems that _UNICODE needs to be defined for  
the WIN32 case (if the unicode wxWidgets library is used).

No, not really. Even Dr. Google is not that helpful, only in http://forum.amule.org/index.php?topic=14588.0 
  is a reference to this error. At least we find here:

"The problem is with a macro which replaces function names. You can  
try to include <wx/msw/winundef.h> in the file causing the error, this  
sometimes helps. (This will undefine the macro)"

So, you could try that. If that doesn't work, you should again ask the  
wxWidgets mailing list.

Best Regards,
Werner
