I don't think that the build system will add compiler flags for this sort o= f=20 thing in 4.x, so I believe what you want to do is safe. If you are doing buildworld for the Pentium then remove any arch/cpu specif= ic=20 optimisations and you should be right. =2D --=20 Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C =2D----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFAwESw5ZPcIHs/zowRAgKMAJ9kiiYoY+IyAIhdxO9Ji8/Z/r0IgwCfWpCW eFGnGrq3pEegJ0vn7GJmaDU=3D =3DEA2X =2D----END PGP SIGNATURE-----
