I only have the X11 and Win32 video patched. The Win32 patch also adds support for WGL_ARB_pixel_format, as it was required for getting a multisample capable pixel format. No additional GL header files are required to compile on either platform (though you need an up-to-date glx.h for X11). Requesting a multisample pixel format is made possible using SDL_GL_SetAttribute with the two new SDL_GLattr's I've added (SDL_GL_SAMPLE_BUFFERS and SDL_GL_SAMPLES). I've been using SDL in my projects for quite a while now, so I am happy to contribute back to the project. Now you can have and control FSAA in your SDL/GL apps at the application level!
