Mmm (on i386 and with 3.07+2) :

 $ cat hello.ml
 Printf.printf "Hello World!\n"
 $ ocamlc hello.ml -o hello.byte
 $ ls -l hello.byte
 36025 hello.byte
 $ ocamlc hello.ml -custom -o hello.custom
 $ ls -l hello.custom
 181718 hello.custom
 $ ocamlopt hello.ml -o hello.native
 $ ls -l hello.native
 149877 hello.native

That said :

 $ cat hello
 #!/usr/bin/ocamlrun /usr/bin/ocaml
 Printf.printf "Hello World!\n";;
 $ ls -l hello
 68 hello
