I did a bit of googling and found some references claiming that Win64
will never assign system handles that are outside the range
representable as a signed long; and further stating there are standard
macros HandleToLong and LongToHandle to perform those conversions.
So I'd be comfortable with the original coding as long as we used those
macros instead of random casting. Dunno if you think that'd be cleaner
than what you did. (It's also a fair question whether those macros
are available on Win32.)
