| * This header file sets several defines based on the compiler, processor |
| * architecture, and operating system being used. These defines should be used |
| * throughout the code to facilitate porting to new platforms. It is likely that |
| * this file is auto-generated by an autoconf-like tool at some point, as some |
| * things cannot be determined by pre-defined environment alone. |
