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