For 4.2, largely, it is only the grammar that is working. Productions and semantics are mostly missing. Lexical analysis is mostly done, but not in the preprocessor, which still can't handle uint and double literals.

The grammar and token names are reorganized to match the specification, to allow easier comparison between the specification and the working grammar.
