Thank you for the detailed explanation, Enrico. The warning does not both me anymore because of your explanation. However, if it doesn't make any difference at all, I will do what you said to prevent the warning (see the attached patch). If it does change something, then I should leave it alone. Should I commit the attached patch? Scott
