  58  * In order to predefine machine-dependent constants,
  59  * several strings are defined here:
  60  *
  61  * MACHINE      defines the target cpu (by name)
  62  * SYSTEM       defines the target operating system
  63  * COMPILER     defines the target compiler
  64  *
  65  *      The above may be #defined as "" if they are not wanted.
  66  *      They should not be #defined as NULL.
  67  *
  68  * LINE_PREFIX  defines the # output line prefix, if not "line"
  69  *              This should be defined as "" if cpp is to replace
  70  *              the "standard" C pre-processor.
  71  *
  72  * FILE_LOCAL   marks functions which are referenced only in the
  73  *              file they reside.  Some C compilers allow these
  74  *              to be marked "static" even though they are referenced
  75  *              by "extern" statements elsewhere.
  76  *
  77  * OK_DATE      Predefines the compilation date if set TRUE.
  78  *              Not permitted by the Nov. 12, 1984 Draft Standard.
  79  *
  80  * S_CHAR etc.  Define the sizeof the basic TARGET machine word types.
  81  *              By default, sizes are set to the values for the HOST
  82  *              computer.  If this is inappropriate, see the code in
  83  *              cpp3.c for details on what to change.  Also, if you
  84  *              have a machine where sizeof (signed int) differs from
  85  *              sizeof (unsigned int), you will have to edit code and
  86  *              tables in cpp3.c (and extend the -S option definition.)
  87  *
  88  * CPP_LIBRARY  May be defined if you have a site-specific include directory
  89  *              which is to be searched *before* the operating-system
  90  *              specific directories.
