Could you submit the patch, in patch format, on the bugtracker (
http://caml.inria.fr/mantis/view_all_bug_page.php ) or github (
https://github.com/ocaml/ocaml ), so that it can be kept track of? Or is
this not a proposal for inclusion in the codebase, because you are waiting
for an actual release of msvc?
