   tjump@spgs.com contributes:
   If users are building glut code on MS Windows, then they should
   make sure they include windows.h early, let's not get into a
   header definitions war since MS has proven it's capability to
   change header dependencies w/o publishing they have done so.

   So, let's not include windows.h here, as it's not really required and
   MS own gl/gl.h *should* include it if the dependency is there. */

/* 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. */
