Title:
  Gettext function f_ calls Obj.magic on a format string

Status in marionnet:
  New
Status in ocamlbricks:
  New

Bug description:
  Hello,

  In Debian, Marionnet is currently broken. A bug has been submitted:

    https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=860405

  This is due to the f_ function of Gettext_builder calling Obj.magic on
  a format string:

    http://bazaar.launchpad.net/~marionnet-
  drivers/ocamlbricks/trunk/view/head:/GETTEXT/gettext_builder.ml#L61

  Since ocaml 4.02.0, format strings are no longer strings internally,
  but a more complex datatype based on GADTs. Therefore, f_ now triggers
  a segmentation fault.

  To convert a string to a format string, one has to use
  Scanf.format_from_string.
