First stage of adding support for 64-bit integral data types - this

causes "int64_t" and "u_int64_t" to be defined by the configure script,
and causes "missing/bittypes.h" to attempt to define "u_int64_t" in a
fashion that should, with any luck, work on MSVC++ and various flavors
of GNU C on Windows.
