Most of us don't develop on Windows, so changing warning levels on Windows won't really affect what developers see on their own machines, and thus probably doesn't have much value. It might be a good idea to try to clean up some/many cases of shadowed variables, though. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
