It's used like this:

#ifdef jit_init
static jit_state                        _jit = jit_init ();
#else
static jit_state                        _jit;
#endif

which becomes

#ifdef jit_init
  *_jitp = jit_init ();
#else
  memset (*_jitp, 0, sizeof (*_jitp));
#endif

(do this before calling jit_set_pc).
