ocamlbuild runs ocamldep -module on your file so you can experiment by yourself.

In "module X = Module" ocamldep infer a dependency on Module that's all.

Since ocamldep can makes false positive (open A ;; open B ;;)
ocamlbuild do nasty things to get rid of that.

The drawback, is that sometimes ocamlbuild ignore silently some dependencies.
In that case run it with -verbose 1 and look at the _log file.

You will see:

Warning: Failed to build the module B requested by ocamldep

If you do think that's wrong to ignore it, then force it's construction:

ocamlbuild b.cmo

You will see why ocamlbuild ignores it.

Hope it helps,

Cheers,
