| ** 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 |
