This only affects Wayland and DirectFB, as a Unix system generally has X11 support. Other platforms also have different sizes for the C union in question, but are likely the only target for that platform, etc. Apps that might run on Wayland or DirectFB will need to be compiled against new headers from an official 2.0.6 release, or be prepared to force the x11 target, or not use SDL_GetWindowWMInfo(). Fixes Bugzilla #3428.
