h2. General
* translation unit - the unit which is translated to an object file, usually a preprocessed C file
* declaration - introduces a name for a object, function or type
* definition - defines an object (which needs to be allocated) or a function (code generation)
* type definition - defines a struct,union or enum type
* typedef - defines an alias for a type
* identifier - (general) name for an composite type, struct/union member, typedef, object,
function, enumerator or label
- (ordinary) name for a typedef, object, enumerator or function (which live in the same namespace)
* tag - name for a struct, union or enum type, sometimes referring to such a type
h2. Linkage of Declarations / Definitions
* External linkage: All decls/defs with external linkage in the program denote the same object/function.
This means, they are visible in all translation units.
* Internal linkage: All decls/defs within the translation unit denote the same object/function (static keyword).
* No linkage: The declaration denotes a unique entity (not applicable for external decs/defs).
