After a second look at the macros, they really do different stuff in < 3.1 and 
for 3.1 for e.g: the medium release has imedium object in the vtables for < 
3.1 while for 3.1 and above it directly calls release and the imedium object 
is not there any more.


#define VBOX_MEDIUM_RELEASE(arg) \
    (arg)->vtbl->imedium.nsisupports.Release((nsISupports *)(arg))

#else  /* VBOX_API_VERSION >= 3001 */

#define VBOX_MEDIUM_RELEASE(arg) \
    (arg)->vtbl->nsisupports.Release((nsISupports *)(arg))

#endif /* VBOX_API_VERSION >= 3001 */

but still, will try to split the patch without breaking 3.1
