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?
