File "bitv.ml", line 561, characters 57-67:
Integer literal exceeds the range of representable integers of type int

[The actual failure is in ocamldep]

let of_int32_s i = match Sys.word_size with
  | 32 -> { length = 32;
            bits = [| (Int32.to_int i) land max_int;
                      let hi = Int32.shift_right_logical i 30 in
                      (Int32.to_int hi) land 3 |] }
  | 64 -> { length = 32; bits = [| (Int32.to_int i) land 0xffffffff |] }
  | _ -> assert false


Seems the fault is in the constant 0xffffffff which of course
isn't a valid int on my 32 bit machine. You could use

	(0xffff lsl 16) lor 0xffff

instead in the hope the compiler doesn't fold it,
but ultimately if the compiler is smart enough 
you really must use conditional compilation.
