Sorry if I missed this in an earlier discussion, but I couldn't find anything in the list archives. When I build a bytecode-only app, I get warnings like this from dh_ocaml (actually from ocaml-md5sums): W: approx doesn't resolve dependency on unit Foo one for each module Foo in the program. The dependencies on other libs seem to be correct, but it would be nice to silence the warnings somehow. Eric
