I'm running WinXP here. If your code uses SDL, then I might be able to 
compile it myself.

What's RNG? Is that some sort of even distribution routine? I've been 
able to make evenly-distributed random point arrays in the past by 
testing each spot with a circle routine. It can be slow to compute 
sometimes, but it's always nice to have such a point array handy.
