-   which needs to be used - otherwise type t in io_page.ml
-   is different from the allocated bigarray and equality won't
-   hold.
-   Only since 4.02 there is a <caml/version.h>, thus we cannot
-   include it in order to detect the version of the OCaml runtime.
-   Instead, we use definitions which were introduced by 4.02 - and
-   cross fingers that they'll stay there in the future.
-   Once <4.02 support is removed, we should get rid of this hack.
