* config.nt: Configure 64-bit integers for older compilers.
* config.nt: Prepare to configure 64-bit integers for older compilers.
However, temporarily disable this change unless the temporary
symbol WIDE_EMACS_INT is defined.
(EMACS_INT, BITS_PER_EMACS_INT, pI): Define these if __int64 and
"%I64d" work but long long and "%lld" do not.

(EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
on 32-bit hosts that have 64-bit int, so that they can access
large files.
However, temporarily disable this change unless the temporary
symbol WIDE_EMACS_INT is defined.
* lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
