Looks like a possible build issue with non-GCC host compilers (but nobody
complained since 2008 when it was introduced). Should be easy to refactor
with a local type though, just not as nicely encapsulated in 'alignof'.

--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So this might not be a clang extension after all. see
https://github.com/llvm/llvm-project/issues/83658 (and DE-137 discussion in the
meeting minutes: https://www.open-std.org/JTC1/sc22/wg14/www/docs/n3167.pdf ).
