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