Judging by that link you sent me, shouldn't it be:

typedef struct tagVMRGUID
{
#if defined(__cplusplus)
    ::GUID *pGUID, GUID;
#else
    GUID *pGUID, GUID;
#endif
} VMRGUID;

Or am i reading that link wrong?

Main problem is of course the msvc compiler doesn't have that problem, 
but if that ifdef works perhaps it's possible to have it like that.
