Currently warnings only show when explicitly building. Does creating an xcspec and/or xcplugin improve this?

Does creating an xcspec and/or xcplugin improve this?

Actually, yes. Because xcspec provides a way to override 'standard' clang. But is has some issues, not sure about current clang version, but previous one (3.3) cannot compile for Arch64, which means iOS platform.
