| 56 | * Runes (wchar_t) is declared to be an ``int'' instead of the more natural | |
| 57 | * ``unsigned long'' or ``long''. Two things are happening here. It is not | |
| 58 | * unsigned so that EOF (-1) can be naturally assigned to it and used. Also, | |
| 59 | * it looks like 10646 will be a 31 bit standard. This means that if your | |
| 60 | * ints cannot hold 32 bits, you will be in trouble. The reason an int was | |
| 61 | * chosen over a long is that the is*() and to*() routines take ints (says | |
| 62 | * ANSI C), but they use _RUNE_T_ instead of int. By changing it here, you | |
| 63 | * lose a bit of ANSI conformance, but your programs will still work. | |
| 64 | * | |
| 65 | * Note that _WCHAR_T_ and _RUNE_T_ must be of the same type. When wchar_t | |
| 66 | * and rune_t are typedef'd, _WCHAR_T_ will be undef'd, but _RUNE_T remains | |
| 67 | * defined for ctype.h. | |
