  31  * HISTORY
  32  * 02-Feb-86  Glenn Marcy (gm0w) at Carnegie-Mellon University
  33  *      Added check to allow multiple or recursive inclusion of this
  34  *      file.  Added bool enum from machine/types.h for regular users
  35  *      that want a real boolean type.
  36  *
  37  * 29-Dec-85  Glenn Marcy (gm0w) at Carnegie-Mellon University
  38  *      Also change spacing of MAX and MIN to coincide with that of
  39  *      sys/param.h.
  40  *
  41  * 19-Nov-85  Glenn Marcy (gm0w) at Carnegie-Mellon University
  42  *      Changed the number of tabs between TRUE, FALSE and their
  43  *      respective values to match those in sys/types.h.
  44  *
  45  * 17-Dec-84  Glenn Marcy (gm0w) at Carnegie-Mellon University
  46  *      Only define TRUE and FALSE if not defined.  Added caseE macro
  47  *      for using enumerated types in switch statements.
  48  *
  49  * 23-Apr-81  Mike Accetta (mja) at Carnegie-Mellon University
  50  *      Added "sizeofS" and "sizeofA" macros which expand to the size
  51  *      of a string constant and array respectively.
  52  *
