 * The rune type is declared to be an ``int'' instead of the more natural
 * ``unsigned long'' or ``long''.  Two things are happening here.  It is not
 * unsigned so that EOF (-1) can be naturally assigned to it and used.  Also,
 * it looks like 10646 will be a 31 bit standard.  This means that if your
 * ints cannot hold 32 bits, you will be in trouble.  The reason an int was
 * chosen over a long is that the is*() and to*() routines take ints (says
 * ANSI C), but they use _BSD_CT_RUNE_T_ instead of int.  By changing it
 * here, you lose a bit of ANSI conformance, but your programs will still
 * work.

 * the bad reason that (broken) programs might not like clock_t or
 * CLOCKS_PER_SEC being ``double'' (``unsigned long'' is not large enough
 * to hold the required 24 hours worth of ticks if the frequency is
 * 1000000ul, and ``unsigned long long'' would be nonstandard).
