  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.
