FYI: 64 bit platforms issue

Info on type sizes on 64 bit platforms.

-------------

Depends on platform. Most Unix/Linux (incl. Solaris) define a
programming paradigm called "ILP32/ILP64" where:

int == 32 bits
long == 32 or 64 bits, depending on platform
long long == 64 bits
pointer == 32 or 64 bits, depending on platform

Windows, unfortunately, has its own standard called "LLP64" where

int == 32 bits
long == 32 bits
long long == 64 bits
pointer == 32 or 64 bits, depending on platform
