// The DEFINE_CLSID() and DEFINE_IID() macros defined below allow COM GUIDs to
// be declared and defined in such a way that clients can obtain the GUIDs using
// either the __uuidof() extension or the old-style CLSID_Foo / IID_IFoo names.
// If using the latter approach, the client can also choose whether to get the
// GUID definitions by defining the INITGUID preprocessor constant or by linking
// to a GUID library.  This works in either C or C++.
