#define GLUT_DISABLE_ATEXIT_HACK

Disable GLUT ataxit workaround on windows.

Win32 has an annoying issue where there are multiple C run-time libraries (CRTs). If the executable is linked with a different CRT from the GLUT DLL, the GLUT DLL will not share the same CRT static data seen by the executable. In particular, atexit callbacks registered in the executable will not be called if GLUT calls its (different) exit routine). GLUT is typically built with the "/MD" option (the CRT with multithreading DLL support), but the Visual C++ linker default is "/ML" (the single threaded CRT).

One workaround to this issue is requiring users to always link with the same CRT as GLUT is compiled with. That requires users supply a non-standard option. GLUT 3.7 has its own built-in workaround where the executable's "exit" function pointer is covertly passed to GLUT. GLUT then calls the executable's exit function pointer to ensure that any "atexit" calls registered by the application are called if GLUT needs to exit.

To avoid the atexit workaround, define GLUT_DISABLE_ATEXIT_HACK.
