Alternatively, you can instruct ocamlrpcgen to directly translate RPC
int's to int/int32/int64. E.g. "ocalmrpcgen -int unboxed", or
you demand the types in the .x file, e.g. use "_unboxed int".

See the manual for details: 
http://projects.camlcity.org/projects/dl/ocamlnet-3.0.3/doc/html-main/Rpc_intro.html,
section "Mapping integer types".
