(* FIXME: Ocaml is not running this setup code unless we use 'val' in the
interface, which causes the emission of a stub for each function;
using 'external' in the module allows direct calls into
ocaml_executionengine.c. This is hardly fatal, but it is unnecessary
overhead on top of the two stubs that are already invoked for each
call into LLVM. *)
