For this project, I'm trying to support all versions of windows, even 
those old beasties 95, 98, and ME.

(The project is a library for reporting anonymous statistics about user 
behavior. Failing to support the older operating systems would create a 
bias in the reporting that I'd rather avoid.)

And, if at all possible, I'd rather just compile a single binary, even 
if it means jumping through some weird hoops in writing my code. Is 
there any feasible solution?
