If anything worries me it's forward compatibility should Microsoft
change the function signature. Backwards compatibility can always
be guaranteed by using GetProcAddress(). Again, I would be very
surprised but IF it could be quite fatal.
Anyway, we don't know for sure if it's faster or if it fixes the DST
problem of FindFirstFile(). I'll write some code to try it out.
