On at least one 64-bit platform (I think at least XCode 4.6.3 / gcc 4.2 on Mountain Lion) one
of the two is defined to be "long" and the other "long long".  Even though both of those are
64 bits, gcc "knows" that there are platforms where long is only 32 bits, and hence this could
be a problem when you recompile on different platform.

Thus the warnings, against future unportability.

Gcc doesn't "know" that we plan to change our macro definitions for that platform.
