Good point. I'm afraid that as we're up to Win2k+ here
almost across the board, I've tended to stop checking 
platform-specific stuff as closely as I used to when 
we were supporting large amounts of Win9x. Sorry.

I've added a page to my own site outlining the different
techniques, and I'll add something to it warning about
Windows version dependencies.

I'm not in a position to test at the moment, but as far as I
recall the pywin32 code in general does do a check for whether
a function is available before it builds it in. Haven't checked.
