** This file is included at the start of 'C' or 'C++' source file to define
** things for cross-platform/compiler interoperability. This used to deal with
** MSDOS/16-bit stuff, but this was all removed in Decemeber 2010. There are
** three things to consider: Windows, LINUX, mac OSX (BSD Unix) and 32 vs 64
** bit. At the time of writing (DEC 2010) there is a consensus on the following
** and their unsigned equivalents:
**
** type bits
** char 8
** short 16
** int 32
** long long 64
**
** long is a problem as it is always 64 bits on linux/unix and is always 32 bits
** on windows.
** On windows, we define _IS_WINDOWS_ and one of WIN32 or WIN64.
** On linux we define LINUX
** On Max OSX we define MACOSX
