Last year I'd be stunned. But I spend so much time getting svn,
swig, and things to work on Windows these days, I'm used to it.

I'm afraid it may be too expensive to turn buffering off
completely, if my experience with Windows performance in general
(and the stock terminal emulator in specific) is any indication.
So, it's probably best to change stdout only in #ifndef WIN32.

That's just a thought; I'll defer to people with more Windows
