     83  * Runes (wchar_t) is declared to be an ``int'' instead of the more natural
     84  * ``unsigned long'' or ``long''.  Two things are happening here.  It is not
     85  * unsigned so that EOF (-1) can be naturally assigned to it and used.  Also,
     86  * it looks like 10646 will be a 31 bit standard.  This means that if your
     87  * ints cannot hold 32 bits, you will be in trouble.  The reason an int was
     88  * chosen over a long is that the is*() and to*() routines take ints (says
     89  * ANSI C), but they use _RUNE_T_ instead of int.  By changing it here, you
     90  * lose a bit of ANSI conformance, but your programs will still work.
     91  *
     92  * Note that _WCHAR_T_ and _RUNE_T_ must be of the same type.  When wchar_t
     93  * and rune_t are typedef'd, _WCHAR_T_ will be undef'd, but _RUNE_T remains
     94  * defined for ctype.h.
