[Caml-list] Warnings while compiling a static OCaml program

[David MENTRE <dmentre@linux-france.org>]

Hello,

I obtain following warnings when I compile my OCaml program in static,
native code:

I've googled and look into glibc and gcc info pages but found
nothing. Could somebody more informed explain to me where those warnings
are coming from and how I might solve the possible issue?

Many thanks in advance for any help,
Yours,
