I'll check the off-by-one fix in tomorrow, as I'm off to bed now. 

As for the &'s, I wonder if it's a w32api reference issue? The compiler
complains if they are present for me.

I have the latest-and-greatest w32api headers on my system - what do you
have?

Thanks for finding the off-by-one... blush.
