--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
It is a little more complex than this.

It is enabled by both -Wall and -Wextra.

For all languages it is enabled by -Wextra.

For Fortran and C/C++ (and objc/objc++) it is enabled by -Wall .

The -Wall is a language specific flag which causes confusion really. But that
is recorded as PR 117009.

The LTO issue of -Wall not enabling -Wuninitialize is recorded as PR 90844 (but
that is still -Wall really)
