Agree.

I just didn't know 'alignas()' (a.k.a. '_Alignas()'), so I used 
attributes and only changed the syntax.  But yes, we should use that C11 
feature.  Given that we already used 'noreturn' and not '_Noreturn' (see 
exit(3) and its family), I'll use 'alignas()'.

I'll send a v2 with those changes.

Thanks,

Alex
