and i stand by that ;)

which is why glib provides in gatomic.h:
  gint     g_atomic_int_get                      (volatile gint     *atomic);
  void     g_atomic_int_set                      (volatile gint     *atomic,
                                                  gint               newval);
  gpointer g_atomic_pointer_get                  (volatile gpointer *atomic);
  void     g_atomic_pointer_set                  (volatile gpointer *atomic,
                                                  gpointer           newval);
these provide portable atomic access to int and gpointer.
