+/* Comment from glut.h of classic GLUT:
+
+ 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.
+
+ Note that the __glut*WithExit routines should NEVER be called directly.
+ To avoid the atexit workaround, #define GLUT_DISABLE_ATEXIT_HACK. */
