      dependencies are merged from: src/parser/parser.mli
         src/parser/parser.ml
      targets that depend on this node at this point:

+ menhir --infer --explain --dump --ocamlc 'ocamlfind ocamlc -warn-error A
-g -I .' parser.mly
File "parser.mly", line 3, characters 2-10:
Unbound module Ast

So the dep is showing up for the .cm* files, but not for the .ml, which is
required for menhir --infer.  Unfortunately, I don't quite grok the
scanner rules in OCaml.om, so I'm not sure how to track this down :-/
