-Wformat-truncation looks for places where the return code of snprintf() is unchecked and the provided buffer might be too short. This is based on a heuristic that can change between compiler versions. It has been seen to get this wrong in ddt_object_name(), leading to DDT_NAMELEN being increased somewhat arbitrarily. There's no good reason to have this warning enabled, so here we disable it everywhere. Truncation may be undesirable, but snprintf() is guaranteed to emit a trailing null, so at worst we get a short string, not a buffer overrun.
