/**
 * g_atexit:
 * @func: the function to call on normal program termination.
 * 
 * Specifies a function to be called at normal program termination.
 *
 * Since GLib 2.8.2, on Windows g_atexit() actually is a preprocessor
 * macro that maps to a call to the atexit() function in the C
 * library. This means that in case the code that calls g_atexit(),
 * i.e. atexit(), is in a DLL, the function will be called when the
 * DLL is detached from the program. This typically makes more sense
 * than that the function is called when the GLib DLL is detached,
 * which happened earlier when g_atexit() was a function in the GLib
 * DLL.
 *
 * The behaviour of atexit() in the context of dynamically loaded
 * modules is not formally specified and varies wildly.
 *
 * On POSIX systems, calling g_atexit() (or atexit()) in a dynamically
 * loaded module which is unloaded before the program terminates might
 * well cause a crash at program exit.
 *
 * Some POSIX systems implement atexit() like Windows, and have each
 * dynamically loaded module maintain an own atexit chain that is
 * called when the module is unloaded.
 *
 * On other POSIX systems, before a dynamically loaded module is
 * unloaded, the registered atexit functions (if any) residing in that
 * module are called, regardless where the code that registered them
 * resided. This is presumably the most robust approach.
 *
 * As can be seen from the above, for portability it's best to avoid
 * calling g_atexit() (or atexit()) except in the main executable of a
 * program.

 * For example, if LANGUAGE=de:en_US, then the returned list is
 * "de", "en_US", "en", "C".
 *
 * This function consults the environment variables <envar>LANGUAGE</envar>, 
 * <envar>LC_ALL</envar>, <envar>LC_MESSAGES</envar> and <envar>LANG</envar> 
 * to find the list of locales specified by the user.
