Hi Jean-Daniel,

We already have __has_feature(generic_selections).

Prefixing C features with c_ is unprecedented (and it would of course
be a bad idea to rename the existing C features/extensions) so I think
that for the sake of consistency the C1X static assert feature should
just be called "static_assert".

Also, C1X static assertions are supported as an extension in all
languages so the feature should not be predicated on the C1X language
option.

Thanks,
