--- Comment #15 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Hi Paul, could you please submit the patch to the gcc-patches mailing list for
formal review, CCing the libstd...@gcc.gnu.org list?

Please either complete a copyright assignment to the FSF or use DCO sign-off as
per https://gcc.gnu.org/dco.html so that we can use your patch in GCC.

Thanks!
