I think it is quite a lot of work to get all = of these right, and it should really be discussed upstream. So for now, I would advise to only turn on the flang option for amd64 by = default. -Dimitry --Apple-Mail=_73807854-0A8A-41CA-A301-8309F9FC216B Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.2 iF0EARECAB0WIQR6tGLSzjX8bUI5T82wXqMKLiCWowUCYZKpugAKCRCwXqMKLiCW o68qAKDP8WfByS2UovTvl8L2lHFYdYuBFwCgqi2aK0EdPp2/jZ8CuDTUGX2s+Bg= =xxGf -----END PGP SIGNATURE----- --Apple-Mail=_73807854-0A8A-41CA-A301-8309F9FC216B--
