--- Comment #8 from Rich Felker <bugdal at aerifal dot cx> --- There's already the GNU C __alignof__ which is free to do whatever GCC prefers, so I fail to see the usefulness of making _Alignof do something nonstandard (and IMO, utterly illogical) that might conflict with future standards. I would prefer that __Alignof(expr) produce either an error, or __Alignof(__typeof__(expr)).
