[sword-devel] Building on ppc64

The standard way to get signed/unsigned integer types with a specified
width is to

    #include <stdint.h> // in C99 and C++03

or

    #include <cstdint> // in C++11 and later

and then use the defined int#_t, uint#_t types (or *int_fast#_t,
*int_least#_t, *intptr_t, *intmax_t depending on your needs).

I don't see a reason to define our versions of signed/unsigned integer
types unless they're missing on the target platform. Usually the
standard headers do stuff like this better than we can anyway.

Blessings,
Jaak
