In C, REFPROPERTYKEY becomes PROPERTYKEY*, in C++ it's PROPERTYKEY &,
so IsEqualPropertyKey will need a different macro. The psdk doesn't
define this properly for the C case, but since I need it in C code I
need it defined, unless you want me to do IsEqualPropertyKey(*key1,
*key2), but even that wouldn't work because of the IsEqualIID..

Cheers,
Maarten.
