I'm not sure if that should be the solution. At least gcc's libstdc++ assumes that `stdalign.h` is C++-compatbile (cf. https://github.com/gcc-mirror/gcc/blob/16e2427f50c208dfe07d07f18009969502c25dc8/libstdc%2B%2B-v3/include/c_global/cstdalign). Clang provides a compatible header: https://github.com/llvm/llvm-project/commit/8acb4044d83ecc9df81b1c9f327d5bd4325e1756. Gcc too of course: https://github.com/gcc-mirror/gcc/blob/16e2427f50c208dfe07d07f18009969502c25dc8/gcc/ginclude/stdalign.h. MSVC's STL on the other hand, doesn't include `<stdalign.h>` (https://github.com/microsoft/STL/blob/main/stl/inc/cstdalign). @hubert.reinterpretcast, are you aware of an environment which has non-friendly `stdalign.h`?
