   18:  *      Machine type definition
   19:  *
   20:  *      Describes differences between platforms, such as hardware
   21:  *      and OS. Where the source code must be differentiated
   22:  *      according to platform, macros and other definitions given
   23:  *      here should be used.
   24:  *
   25:  *      Where possible, classifications should be based on general
   26:  *      attributes rather than the machine type. Thus, the endian,
   27:  *      for instance, should be described as BIGENDIAN rather than
   28:  *      using a classification based on the machine type.
   29:  *
   30:  *      * Machine type definition is not used solely by the machine
   31:  *      C language source file, so non-macro definitions are not
   32:  *      permitted.
