Preprocessing with /lib/cpp is possible:

-------------------------------------------------- main.ml
#include "main-part1.ml"
#include "main-part2.ml"

-------------------------------------------------- main-part1.ml
let v1 = 1

-------------------------------------------------- main-part2.ml
let v2 = v1 + 1;;
print_endline ("v2 = " ^ string_of_int v2);;



$ ocamlc -pp /lib/cpp main.ml
$ ./a.out 
v2 = 2
