That's great. I'm up against a mysql upgrade that doesn't want to go through without the new gcc, so I'm going for it now. I have 4 desktops on a non-hardened profile and 1 server on a hardened profile. I'd love to put the desktops on a hardened profile with this new gcc. Can I switch from non-hardened to hardened? - Grant
