  72  * In order to predefine machine-dependent constants,
  73  * several strings are defined here:
  74  *
  75  * MACHINE      defines the target cpu (by name)
  76  * SYSTEM       defines the target operating system
  77  * COMPILER     defines the target compiler
  78  *
  79  *      The above may be #defined as "" if they are not wanted.
  80  *      They should not be #defined as NULL.
  81  *
  82  * LINE_PREFIX  defines the # output line prefix, if not "line"
  83  *              This should be defined as "" if cpp is to replace
  84  *              the "standard" C pre-processor.
  85  *
  86  * FILE_LOCAL   marks functions which are referenced only in the
  87  *              file they reside.  Some C compilers allow these
  88  *              to be marked "static" even though they are referenced
  89  *              by "extern" statements elsewhere.
  90  *
  91  * OK_DOLLAR    Should be set TRUE if $ is a valid alphabetic character
  92  *              in identifiers (default), or zero if $ is invalid.
  93  *              Default is TRUE.
  94  *
  95  * OK_CONCAT    Should be set TRUE if # may be used to concatenate
  96  *              tokens in macros (per the Ansi Draft Standard) or
  97  *              FALSE for old-style # processing (needed if cpp is
  98  *              to process assembler source code).
  99  *
 100  * OK_DATE      Predefines the compilation date if set TRUE.
 101  *              Not permitted by the Nov. 12, 1984 Draft Standard.
 102  *
 103  * S_CHAR etc.  Define the sizeof the basic TARGET machine word types.
 104  *              By default, sizes are set to the values for the HOST
 105  *              computer.  If this is inappropriate, see the code in
 106  *              cpp3.c for details on what to change.  Also, if you
 107  *              have a machine where sizeof (signed int) differs from
 108  *              sizeof (unsigned int), you will have to edit code and
 109  *              tables in cpp3.c (and extend the -S option definition.)
 110  *
 111  * CPP_LIBRARY  May be defined if you have a site-specific include directory
 112  *              which is to be searched *before* the operating-system
 113  *              specific directories.
