77 * rune_t is declared to be an ``int'' instead of the more natural
78 * ``unsigned long'' or ``long''.  Two things are happening here.  It is not
79 * unsigned so that EOF (-1) can be naturally assigned to it and used.  Also,
80 * it looks like 10646 will be a 31 bit standard.  This means that if your
81 * ints cannot hold 32 bits, you will be in trouble.  The reason an int was
82 * chosen over a long is that the is*() and to*() routines take ints (says
83 * ANSI C), but they use __ct_rune_t instead of int.
84 *
85 * NOTE: rune_t is not covered by ANSI nor other standards, and should not
86 * be instantiated outside of lib/libc/locale.  Use wchar_t.  wint_t and
87 * rune_t must be the same type.  Also, wint_t should be able to hold all
88 * members of the largest character set plus one extra value (WEOF), and
89 * must be at least 16 bits.
