--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> --- https://gcc.gnu.org/onlinedocs/gcc/Alignment.html should discuss the relationship between GCC's __alignof__ and C11's _Alignof. Are they identical? Should _Alignof be preferred when using C11? It could also mention _Alignas, and the macros (keywords in C++11 and later) alignof and alignas.
