     73  * Runes (wchar_t) is declared to be an ``int'' instead of the more natural
     74  * ``unsigned long'' or ``long''.  Two things are happening here.  It is not
     75  * unsigned so that EOF (-1) can be naturally assigned to it and used.  Also,
     76  * it looks like 10646 will be a 31 bit standard.  This means that if your
     77  * ints cannot hold 32 bits, you will be in trouble.  The reason an int was
     78  * chosen over a long is that the is*() and to*() routines take ints (says
     79  * ANSI C), but they use _RUNE_T_ instead of int.  By changing it here, you
     80  * lose a bit of ANSI conformance, but your programs will still work.
     81  *
     82  * Note that _WCHAR_T_ and _RUNE_T_ must be of the same type.  When wchar_t
     83  * and rune_t are typedef'd, _WCHAR_T_ will be undef'd, but _RUNE_T remains
     84  * defined for ctype.h.
