Form 3:
  #define DEF_SAT_S_TRUNC_FMT_3(NT, WT, NT_MIN, NT_MAX) \
  NT __attribute__((noinline))                          \
  sat_s_trunc_##WT##_to_##NT##_fmt_3 (WT x)             \
  {                                                     \
    NT trunc = (NT)x;                                   \
    return (WT)NT_MIN < x && x <= (WT)NT_MAX            \
      ? trunc                                           \
      : x < 0 ? NT_MIN : NT_MAX;                        \
  }
