--- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> ---
One more comment here. I do cooperate with our openSUSE maintainer of Chromium
package and they have quite some of these warnings when building with GCC. I
told him he can strengthen behavior with -fstrict-enums option. Once we did
that the package crashes during build.
