Under my Linux, it is /usr/share/magic. It works.

They are files holding syntax trees generated by camlp4. E.g.:
      camlp4o myfile.ml -o foobar.ml

The file "foobar.ml" is an ast_impl file. It is binary but compilable:
      ocamlc -c foobar.ml

The compiler loads the binary tree, the syntactic analysis is skipped
and the possible error messages show the initial file (myfile.ml).

With your magic file:
      file foobar.ml
      foobar.ml: Objective Caml 'ast_impl' file (Version 008).
