To overcome this problem you can execute either
ocamlbuild -cflag -inline -cflag 2 target.native
or
ocamlbuild -cflags -inline,2 target.native

This is a reported bug [1]; in your case, a workaround is to write the
following "myocamlbuild.ml" file:
open Ocamlbuild_plugin
let () =
dispatch begin function
| After_rules ->
tag_file "target.ml" ["myoption"];
flag ["ocaml"; "compile"; "native"; "myoption"] (A"-S");
| _ -> ()
end
Hope this helps,
