* There are 2 different ways to indicate a symbol is undefined:
* 1) sctab.flag = UNDEFINED
* 2) or sctab.value = -1 (and if !UNDEFINED and !UNSIGNED_VALUE)

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