60 * Notes:
61 * The sctab.value field is defined to be a long.
62 * There are some values that are "unsigned long"; these values
63 * can be stored in a "long" field but when output, must be printed
64 * as an unsigned value. Thus, these values must have UNSIGNED_VALUE bit
65 * set in sctab.flag field.

68 * 1) sctab.flag = UNDEFINED
69 * 2) or sctab.value = -1 (and if !UNDEFINED and !UNSIGNED_VALUE)

71 * There are a group of symbols (e.g CHAR_MIN, INT_MAX, INT_MIN, LONG_BIT ...)
72 * which we may set to -1 if they are not pre-defined in a system header file.
73 * This is used to indicate that these symbols are "undefined".
74 * We are assuming that these symbols cannot reasonably have a value of -1
75 * if they were defined in a system header file.
