GNU Emacs, master branch, latest commits, e.g. 0275c54ca80124f8a6e3a9823844b9ee131443cc, fails to build. The full build error for attempting to install Emacs with Guix ("guix install emacs-next-tree-sitter --with-branch=emacs-next-tree-sitter=master") is attached. FreeBSD also has this issue. They seem to work it around by disabling NATIVECOMP. So, it seems to related to native compilation. https://cgit.freebsd.org/ports/commit/?id=73560fbfd1950eec2da204856d5698905e299273 Garuda Linux also seems to have this issue. https://builds.garudalinux.org/repos/chaotic-aur/logs/emacs-pgtk-native-comp-git.log
