Detailed Description

DefinedTracker - This struct is used while parsing expressions to keep track of whether !defined(X) has been seen.

With this simple scheme, we handle the basic forms: !defined(X) and !defined X but we also trivially handle (silly) stuff like: !!!defined(X) and +!defined(X) and !+!+!defined(X) and !(defined(X)).
