What's next?
(Value & 0xFFFF) -> warning because ANDing an ULONG64 is regarded as 
"silencing a warning" -> fix: 
__really_truncate_this_unsigned_int64_to_ushort_and_discard_lost_bits(Value); 
?

For me casting *is* already doing it "explicitly". And if someone 
doesn't know that casting is the same as truncating, he shouldn't do C 
coding.

I agree with Aleksey: turn this feature off, its a bit too much.
