Have a look to the FAQ:

http://pauillac.inria.fr/caml/FAQ/pgl-eng.html#avertissements

paragraph entitled ``Sequence warnings''.

Different ways of getting rid of the warning are discussed, including
the most demanding one (and, to my knowledge, the best one): ``understand why
(the warning) is emitted by the compiler''.

Best regards,
