WTF is with the new GCC coming out with 752 new compiler optimizations but then changing the syntax after the just changed it 1 version ago? I was working on a Mac the other day and this made my head almost explode as two different versions of the program I was using were compiled with the GCC that came with Snow Leopard and the GCC that came with whatever the hell the last OS X was called.
I'm not going to look up the version numbers. If you care, you are a nerd.
