64 * rune_t is declared to be an ``int'' instead of the more natural
65 * ``unsigned long'' or ``long''. Two things are happening here. It is not
66 * unsigned so that EOF (-1) can be naturally assigned to it and used. Also,
67 * it looks like 10646 will be a 31 bit standard. This means that if your
68 * ints cannot hold 32 bits, you will be in trouble. The reason an int was
69 * chosen over a long is that the is*() and to*() routines take ints (says
70 * ANSI C), but they use __ct_rune_t instead of int.
71 *
72 * NOTE: rune_t is not covered by ANSI nor other standards, and should not
73 * be instantiated outside of lib/libc/locale. Use wchar_t. wchar_t and
74 * rune_t must be the same type. Also, wint_t must be no narrower than
75 * wchar_t, and should be able to hold all members of the largest
76 * character set plus one extra value (WEOF), and must be at least 16 bits.
