--- Comment #19 from Jonathan Wakely <redi at gcc dot gnu.org> --- I've backported stdbit.h and stdckdint.h to the gcc-14 branch, so this case should work with GCC 14.4 * Clang + libstdc++ 14: fails To fix GCC + libc++ will require the changes to gcc/ginclude/stdckdint.h that Jakub suggested in comment 15.
