This is the coherent with the behaviour I have on my mcahine. The file m1.ml has
no side-effects (it merely declares a function) hence does nothing when
executed. (It is not related to flushing the buffers.)

In the man page for ocaml, the [script-file] argument is not given as plural,
nor does the explanation about this argument:
       If a script-file is given, phrases are read silently from the file,
       errors printed on standard error.  ocaml(1) exits after  the  execution
       of the last phrase.

Hence, you can only give one .ml file. To execute several files, you need to
compile. (Which, as noted by thomas, can be quite fast for bytecode
compilation.)

$ ocamlbuild m2.byte
$ ./m2.byte
