Free-vars
A utility to collect free variables over a C AST.
This returns a set of all identifiers used as variables within the AST,
excluding those variables which have first been declared, i.e. in a
statement declaration or as a function parameter.
It only considers variables of regular data object, not other types of
named language constructs, such as typedef type names.
