Please don't remove old test (the way how the function is called needs 
to be changed but the arguments can be preserved).

This comment is not really needed, please remove it.

I'm not sure if it's still the case but we were avoiding LONGLONG 
constants for compatibility reasons. That's why the tests were using 
(ULONGLONG)0x... << 32 | 0x... to compute the values.

Thanks,
