Or write it as (!field || !(typeof(field))~field) which more closely resembles what the macro name expresses.Better still, or maybe: field == 0 || field == (typeof field)~0
Which doesn't work when sizeof(field) > sizeof(int). Needs another cast. field == 0 || field == (typeof field)~(typeof field)0 David
