The reason an int was 70 * chosen over a long is that the is*() and to*() routines take ints (says 71 * ANSI C), but they use _RUNE_T_ instead of int. By changing it here, you 72 * lose a bit of ANSI conformance, but your programs will still work. 73 * 74 * Note that _WCHAR_T_ and _RUNE_T_ must be of the same type.
