It's a known issue. (The technical issue is that Coot uses STL strings which can return a const char*, whereas mmdb uses pstr which is typedef'ed to a const char*. From gcc 4.3 these are no longer equivalent for some reason.). For now it is just a warning, so you can ignore it. We're looking into a proper fix.
