obrien b8425680b5 Make _BSD_TIME_T_ (time_t) an int' rather than long'. This will help
flag errors where programmers assume time_t is a long, which it is not on
64-bit platforms.

* The rune type above 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.
*
* NOTE: rune_t is not covered by ANSI nor other standards, and should not
* be instantiated outside of lib/libc/locale. Use wchar_t. wchar_t and
* rune_t must be the same type. Also wint_t must be no narrower than
* wchar_t, and should also be able to hold all members of the largest
* character set plus one extra value (WEOF). wint_t must be at least 16 bits.
