Two things are happening here. It is not 114 * unsigned so that EOF (-1) can be naturally assigned to it and used. Also, 115 * it looks like 10646 will be a 31 bit standard. This means that if your 116 * ints cannot hold 32 bits, you will be in trouble. The reason an int was 117 * chosen over a long is that the is*() and to*() routines take ints (says 118 * ANSI C), but they use __ct_rune_t instead of int. By changing it here, you 119 * lose a bit of ANSI conformance, but your programs will still work. 120 * 121 * NOTE: rune_t is not covered by ANSI nor other standards, and should not 122 * be instantiated outside of lib/libc/locale. Use wchar_t. wchar_t and 123 * rune_t must be the same type. Also wint_t must be no narrower than 124 * wchar_t, and should also be able to hold all members of the largest 125 * character set plus one extra value (WEOF). wint_t must be at least 16 bits. 126 */ 127typedef __int32_t __ct_rune_t; 128typedef __int32_t __rune_t; 129typedef __int32_t __wchar_t; 130typedef __int32_t __wint_t; 131 132/* 133 * mbstate_t is an opaque object to keep conversion state, during multibyte 134 * stream conversions.
