Comment:

 I found many other projects with this error. As far as I can tell,
 `aligned_alloc` is for C code (C11 and later) while `std::aligned_alloc`
 is for C++ code (C++17 and later). This file being compiled here is C++
 code so perhaps it should be using `std::aligned_alloc` instead of
 `aligned_alloc`. The port succeeded building on macOS 10.15 and later;
 maybe later versions of clang are more relaxed about this distinction or
 maybe the default C language mode is newer in newer version of clang.
