[Caml-list] -custom switch useless??

[Stefano Zacchiroli <zack@cs.unibo.it>]

  I'm building an ocaml package from sources and seems to me that
-custom switch on ocamlc compiler has no effect.
I'm building ocaml findlib and from the Makefile:

ocamlfind: findlib.cma $(OCAMLFIND_OBJECTS)
 $(OCAMLC) -custom -g -o ocamlfind findlib.cma unix.cma \
            $(OCAMLFIND_OBJECTS)

with -custom switch ocamlfind is linked with the interpreter and the
resulting file is a regular ELF executable that contains both the
interpreter and the bytecode.

Well, if I remove the -custom switch nothing changes!  I obtain the same
file and not a #!/usr/bin/ocamlrun executable as I expected, the two
files are identical (diff tested).

If I try the same with a stupid hello_world.ml test:

  let main () = print_string "Hello, world!\n";;
  main ();;

all work as expected (ocamlrun executable without -custom, linked
version with -custom).

Why this difference?

TIA, cheers.
