57 1.4 cgd * Runes (wchar_t) is declared to be an ``int'' instead of the more natural
58 1.4 cgd * ``unsigned long'' or ``long''. Two things are happening here. It is not
59 1.4 cgd * unsigned so that EOF (-1) can be naturally assigned to it and used. Also,
60 1.4 cgd * it looks like 10646 will be a 31 bit standard. This means that if your
61 1.4 cgd * ints cannot hold 32 bits, you will be in trouble. The reason an int was
62 1.4 cgd * chosen over a long is that the is*() and to*() routines take ints (says
63 1.4 cgd * ANSI C), but they use _RUNE_T_ instead of int. By changing it here, you
64 1.4 cgd * lose a bit of ANSI conformance, but your programs will still work.
65 1.4 cgd *
66 1.4 cgd * Note that _WCHAR_T_ and _RUNE_T_ must be of the same type. When wchar_t
67 1.4 cgd * and rune_t are typedef'd, _WCHAR_T_ will be undef'd, but _RUNE_T remains
68 1.4 cgd * defined for ctype.h.
