--- Comment #3 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- What makes you think _Alignof depends on -std=c11 (other than for -pedantic diagnostics)? I don't see any point in requesting alignment of an object, as opposed to a type, unless you want a result that can sometimes be bigger than what you get from _Alignof applied to the type.
