+ 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. */

+ * Adopters may modify this file to suit their platform. Adopters are
+ * encouraged to submit platform specific modifications to the Khronos
+ * group so that they can be included in future versions of this file.
+ * Please submit changes by sending them to the public Khronos Bugzilla
+ * (http://khronos.org/bugzilla) by filing a bug against product
+ * "Khronos (general)" component "Registry".
+ *
+ * A predefined template which fills in some of the bug fields can be
+ * reached using http://tinyurl.com/khrplatform-h-bugreport, but you
+ * must create a Bugzilla login first.
+ *
+ *
+ * See the Implementer's Guidelines for information about where this file
+ * should be located on your system and for more details of its use:
+ * http://www.khronos.org/registry/implementers_guide.pdf
+ *
+ * This file should be included as
+ * #include <KHR/khrplatform.h>
+ * by Khronos client API header files that use its types and defines.
+ *
+ * The types in khrplatform.h should only be used to define API-specific types.
+ *
+ * Types defined in khrplatform.h:
+ * khronos_int8_t signed 8 bit
+ * khronos_uint8_t unsigned 8 bit
+ * khronos_int16_t signed 16 bit
+ * khronos_uint16_t unsigned 16 bit
+ * khronos_int32_t signed 32 bit
+ * khronos_uint32_t unsigned 32 bit
+ * khronos_int64_t signed 64 bit
+ * khronos_uint64_t unsigned 64 bit
+ * khronos_intptr_t signed same number of bits as a pointer
+ * khronos_uintptr_t unsigned same number of bits as a pointer
+ * khronos_ssize_t signed size
+ * khronos_usize_t unsigned size
+ * khronos_float_t signed 32 bit floating point
+ * khronos_time_ns_t unsigned 64 bit time in nanoseconds
+ * khronos_utime_nanoseconds_t unsigned time interval or absolute time in
+ * nanoseconds
+ * khronos_stime_nanoseconds_t signed time interval in nanoseconds
+ * khronos_boolean_enum_t enumerated boolean type. This should
+ * only be used as a base type when a client API's boolean type is
+ * an enum. Client APIs which use an integer or other type for
+ * booleans cannot use this as the base type for their boolean.
+ *
+ * Tokens defined in khrplatform.h:
+ *
+ * KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
+ *
+ * KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
+ * KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.
+ *
+ * Calling convention macros defined in this file:
+ * KHRONOS_APICALL
+ * KHRONOS_APIENTRY
+ * KHRONOS_APIATTRIBUTES
+ *
+ * These may be used in function prototypes as:
+ *
+ * KHRONOS_APICALL void KHRONOS_APIENTRY funcname(
+ * int arg1,
+ * int arg2) KHRONOS_APIATTRIBUTES;
