This means that if your 73 * ints cannot hold 32 bits, you will be in trouble. The reason an int was 74 * chosen over a long is that the is*() and to*() routines take ints (says 75 * ANSI C), but they use __ct_rune_t instead of int. 76 * 77 * NOTE: rune_t is not covered by ANSI nor other standards, and should not 78 * be instantiated outside of lib/libc/locale.

Also, wint_t must be no narrower than 80 * wchar_t, and should be able to hold all members of the largest 81 * character set plus one extra value (WEOF), and must be at least 16 bits. 82 * 83 * For compatibility with Solaris, we want to use long in ILP32, and int in 84 * LP64. This is due to historical Solaris legacy.
