60 60 * Notes:
61 61 * The sctab.value field is defined to be a long.
62 62 * There are some values that are "unsigned long"; these values
63 63 * can be stored in a "long" field but when output, must be printed
64 64 * as an unsigned value. Thus, these values must have UNSIGNED_VALUE bit
65 65 * set in sctab.flag field.
66 66 *
67 67 * There are 2 different ways to indicate a symbol is undefined:
68 68 * 1) sctab.flag = UNDEFINED
69 69 * 2) or sctab.value = -1 (and if !UNDEFINED and !UNSIGNED_VALUE)
70 70 *
71 71 * There are a group of symbols (e.g CHAR_MIN, INT_MAX, INT_MIN, LONG_BIT ...)
72 72 * which we may set to -1 if they are not pre-defined in a system header file.
73 73 * This is used to indicate that these symbols are "undefined".
74 74 * We are assuming that these symbols cannot reasonably have a value of -1
75 75 * if they were defined in a system header file.
76 76 * (Unless of course -1 can be used to indicate "undefined" for that symbol)
