Yes, it's in BaseTyps.h:

  #if defined(__cplusplus) && !defined(CINTERFACE)
  //#define interface               struct FAR
  #define __STRUCT__ struct
  #define interface __STRUCT__
  [...]
  #else

  #define interface               struct
  [...]

So there should be no need to do special magic for IUnknown, and it
looks like even the __declspec(novtable) and __declspec(uuid(x))
attributes are supported with -fms-extensions. :)
