Because that's ugly ;)

Seriously, though, I'm working with some more novice programmers, and I want 
to make this as easy as possible for them.  So I'd like to be able to say 
"just put everything in this function and don't worry about it."  I think 
the extra layer of main like Regan suggested is what I'll do.

They'd never make it all the way back to WinMain; they get caught by dmain 
and printed to the console.  It's a consequence of dmain being meant for 
console apps.
