* Runes (wchar_t) is declared to be an ``int'' instead of the more natural

* 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 _RUNE_T_ instead of int. By changing it here, you
* lose a bit of ANSI conformance, but your programs will still work.
*
* Note that _WCHAR_T_ and _RUNE_T_ must be of the same type. When wchar_t
* and rune_t are typedef'd, _WCHAR_T_ will be undef'd, but _RUNE_T remains
* defined for ctype.h.

* the bad reason that (broken) programs might not like clock_t or
* CLOCKS_PER_SEC being ``double'' (``unsigned long'' is not large enough
