  73  * rune_t is declared to be an ``int'' instead of the more natural
  74  * ``unsigned long'' or ``long''.  Two things are happening here.  It is not

  76  * it looks like 10646 will be a 31 bit standard.  This means that if your
  77  * ints cannot hold 32 bits, you will be in trouble.  The reason an int was
  78  * chosen over a long is that the is*() and to*() routines take ints (says
  79  * ANSI C), but they use __ct_rune_t instead of int.
  80  *
  81  * NOTE: rune_t is not covered by ANSI nor other standards, and should not
  82  * be instantiated outside of lib/libc/locale.  Use wchar_t.  wint_t and
  83  * rune_t must be the same type.  Also, wint_t should be able to hold all
  84  * members of the largest character set plus one extra value (WEOF), and
  85  * must be at least 16 bits.
