  53  * The rune type below is declared to be an ``int'' instead of the more natural
  54  * ``unsigned long'' or ``long''.  Two things are happening here.  It is not
  55  * unsigned so that EOF (-1) can be naturally assigned to it and used.  Also,
  56  * it looks like 10646 will be a 31 bit standard.  This means that if your
  57  * ints cannot hold 32 bits, you will be in trouble.  The reason an int was
  58  * chosen over a long is that the is*() and to*() routines take ints (says
  59  * ANSI C), but they use __darwin_ct_rune_t instead of int.  By changing it
  60  * here, you lose a bit of ANSI conformance, but your programs will still
  61  * work.
  62  *
  63  * NOTE: rune_t is not covered by ANSI nor other standards, and should not
  64  * be instantiated outside of lib/libc/locale.  Use wchar_t.  wchar_t and
  65  * rune_t must be the same type.  Also wint_t must be no narrower than
  66  * wchar_t, and should also be able to hold all members of the largest
  67  * character set plus one extra value (WEOF). wint_t must be at least 16 bits.
