I've mailed a proposed workaround to Xin Li, but for now, if you compile world and kernel with gcc, use NO_WERROR=3D and WERROR=3D in your make.conf. Especially the kernel still needs a bunch of fixes to make it work with gcc again. It's a pity the gcc tinderboxes have been taken offline. Maybe this can be added to the FreeBSD Jenkins instance now? -Dimitry --Apple-Mail=_337D66B4-7CFC-4787-9528-CD16300F939A Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP using GPGMail -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.26 iEYEARECAAYFAlRiYcwACgkQsF6jCi4glqPX0wCg7hs/5Hv0DjrvPQY/ZthO34TK XdQAn3HSQ2m1VaerVXk6m+zT5Uz/LF2c =mt8U -----END PGP SIGNATURE----- --Apple-Mail=_337D66B4-7CFC-4787-9528-CD16300F939A--
