26 | ** This file is included at the start of 'C' or 'C++' source file to define | |
27 | ** things for cross-platform/compiler interoperability. This used to deal with | |
28 | ** MSDOS/16-bit stuff, but this was all removed in Decemeber 2010. There are | |
29 | ** three things to consider: Windows, LINUX, mac OSX (BSD Unix) and 32 vs 64 | |
30 | ** bit. At the time of writing (DEC 2010) there is a consensus on the following | |
31 | ** and their unsigned equivalents: | |
32 | ** | |
33 | ** type bits | |
34 | ** char 8 | |
35 | ** short 16 | |
36 | ** int 32 | |
37 | ** long long 64 | |
38 | ** | |
39 | ** long is a problem as it is always 64 bits on linux/unix and is always 32 bits | |
40 | ** on windows. | |
41 | ** On windows, we define _IS_WINDOWS_ and one of WIN32 or WIN64. | |
42 | ** On linux we define LINUX | |
43 | ** On Max OSX we define MACOSX | |
