  9. *    By default the #define for  the DEFINE_GUID macro in compobj.h on the Mac *
  10. *    defines a macro that turns this:                                              *
  11.     DEFINE_OLEGUID(IID_IEnumUnknown, 0x00000100, 0, 0);
  12.     
  13.     into the following declaration
  14.     
  15.     extern "C" const GUID IID_IEnumUnknown;
  16.     
  17.     to actually define the GUID (create the data) you need to #define INITGUID
  18.     before you include compobj.h which will cause initguid.h to be included 
  19.     which will then redefine the DEFINE_OLEGUID macro to generate
  20.     
  21.     extern "C" const GUID IID_IEnumUnknown = { 0x00000100, 0, 0, 0xC0, 0, 0, 0, 0, 0, 0, 0x46 };
  22.     
  23.     If this kind of gross nested macro abuse is considered bad programing style
  24.     I like to remind you that it's done by Microsoft, which is the most successful
  25.     software company in the world so it must be Okay!
