I think it doesn't have to be necessarily using defaulting to -Werror=,
-Werror= involves diagnostic_classify_diagnostic etc.
It could very well be also just testing if the corresponding warning
option isn't explicitly (OPTION_SET_P) disabled and isn't explicitly
-Wno-error=OPTION and c99 or later and conditionally based on that
use error (which would print the [-W...] part though) or warning.
The former would be in system headers too, the latter wouldn't.
We need to decide what exact options we want to turn those errors (and/or
warnings) off or on, -Wno-implicit-int, -w, -Wno-error,
-Wno-error=implicit-int, ...
