Look at the grammar from the back of K&R. It requires TYPE tokens when you
have definitions. However,
the lexer will produce an ID token unless you look it up in a table. So
this is feedback from the 'typedef'
to the lexer. So we at least need feedback to the lexer from the parse. I
know we need feedback from cpp
to the lexer. I will think of it.
