+ * 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. wchar_t and
+ * rune_t must be the same type. Also, wint_t must be no narrower than
+ * wchar_t, and should be able to hold all members of the largest
+ * character set plus one extra value (WEOF), and must be at least 16 bits.
