Re: [Caml-list] printing the AST of a caml function

I'm not sure this is the cleanest way (i'd rather use something like
-nostdlib), but your two last "lexing.cmx" and "format.cmx" are
actually the same as the standard library modules. You can just remove
them both from your build script, and it will then works.
