Generic red-black trees

Ooh, I didn't even think about 16-bit ints. Thanks for the info on msvc. I did finally discover that empty macro arguments is part of the C99 standard -- no surprise that msvc doesn't fully support it yet, but nice to know that there's a work-around!

I don't have this on any web site right now. fail2ban is screwed up on my machine atm, so I closed all my firewall holes until I get it fixed, otherwise, I would make it available from here. Locally, I need to squash a few commits and amend comments and I can post something somewhere.

As far as GPL w/ link-time exception, I am a believer in that if the business/ethical circumstances warrant it. I have plans for C++11 (w/metaprogramming) game engine toolkit project (if I ever kick it off at all) that will be GPL w/ link-time exception as it's the only way it will get any appreciable commercial support.
