Yes.  The strictly-speaking condition is perhaps strong.  OCaml has been 
reasonably backwards-compatible for minor versions wrt syntax.  But it 
would potentially force a sync with major revisions.

The patch is very simple, let's hope it is accepted (and, if not, 
continue to ask).

Taken into account.  The Boolean variable OCAMLDEP_MODULES_ENABLED 
determines whether the new or old method is used.  This should be set to 
false in MetaPRL because of the custom ocamldep (I haven't committed 
this change to MetaPRL yet).
