A -Wnone on what translation unit?

Example at hand is where `std::optional<int16_t> c{300000};` is warnings
clean because the template is in the system header file. Now, this is a
case where it probably really ought to warn, but doesn't. But it's also a
case where previously clean code is going to fail, but there are probably
cases where the warning is triggered by something the client can't control.
