The new, cleaner, version of the atomic operations. The dummy code is what you should start working with to port atomic ops.

The linux code appears to be complete and *should* be the base of all Unix and GCC based versions. The macosx and win32 versions
are currently just copies of the dummy code. I will begin working on the windows version as soon as this check in is done. I
need someone to work on the Mac OS X version.

I'm afraid that this check in will break QNX (Sorry!)
