73 * unsigned so that EOF (-1) can be naturally assigned to it and used. Also,
74 * it looks like 10646 will be a 31 bit standard. This means that if your
75 * ints cannot hold 32 bits, you will be in trouble. The reason an int was
76 * chosen over a long is that the is*() and to*() routines take ints (says
77 * ANSI C), but they use _BSD_CT_RUNE_T_ instead of int. By changing it
78 * here, you lose a bit of ANSI conformance, but your programs will still

87 * the bad reason that (broken) programs might not like clock_t or
88 * CLOCKS_PER_SEC being ``double'' (``unsigned long'' is not large enough
89 * to hold the required 24 hours worth of ticks if the frequency is
