I think the main issue would be with hardened, where mmx is already a probl= em=20 on some packages, but I think this can be solved. =46or any package where enabling mmx create stability problem, it's likely = the=20 support should be removed altogether anyway, as the flag is enabled for the= =20 majority of users already (the same goes for the other flags). =2D-=20 Diego "Flameeyes" Petten=F2 - http://farragut.flameeyes.is-a-geek.org/ Gentoo/Alt lead, Gentoo/FreeBSD, Video, AMD64, Sound, PAM, KDE --nextPart1449194.VIZyMam6Sx Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.4 (GNU/Linux) iD8DBQBErPK1e2h1+2mHVWMRAt2dAKDm6EuOit1H0x1h+2lmRXvte5DL6gCg54WX M7cB7WV3Ns7C0IPf2LJ7dRA= =5hYO -----END PGP SIGNATURE----- --nextPart1449194.VIZyMam6Sx-- -- gentoo-dev@gentoo.org mailing list
