Last I knew, there were dozens of platforms besides Linux and Windows
<wink>. Like I said, no relationship is defined here. C99 standardizes a
uintptr_t typedef for an unsigned integer type with "enough bits" so that
(void*)(uintptr_t)p == p
for any legit pointer p of type void*, but only standarizes its name, not
its existence (a conforming implementation isn't required to supply a
typedef with this name). Such a type *is* required to compile Python,
though, and pyport.h defines our own Py_uintptr_t (as a synonym for the
platform uintptr_t if it exists, else to the smallest integer type it can
find that looks big enough, else a compile-time #error).

Try to spell out exactly what it is you think this index should be capable
of representing; e.g., what's your most extreme use case?
