--- Comment #13 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
And intersection of all the standards is quite hard to define.
So, adding -std=3Dintersection_of_all_c_standards is just not a good idea, =
any
time same construct changes meaning between different standard you need to
decide what to do.
This is something that should be solved with warnings or external tools and=
 on
the warning side we already have various warnings.=
