Huh?

enum libcall_type
{
  LCT_NORMAL = 0,
  LCT_CONST = 1,
  LCT_PURE = 2,
  LCT_CONST_MAKE_BLOCK = 3,
  LCT_PURE_MAKE_BLOCK = 4,
  LCT_NORETURN = 5,
  LCT_THROW = 6,
  LCT_RETURNS_TWICE = 7
};

enum format_lengths
{
  FMT_LEN_none,
  FMT_LEN_hh,
  FMT_LEN_h,
  FMT_LEN_l,
  FMT_LEN_ll,
  FMT_LEN_L,
  FMT_LEN_z,
  FMT_LEN_t,
  FMT_LEN_j,
  FMT_LEN_H,
  FMT_LEN_D,
  FMT_LEN_DD,
  FMT_LEN_MAX
};
