Nope!  You did NOT rebuild gcc. You installed a new version of gcc, as
gcc is slotted an an update to the portage tree has occurred since
your last install of gcc, and you did not specify to rebuild your
installed version of gcc with emerge =gcc(version)

Clearly I think this is the latter case of rtfm.  And by read the fine
manual, I mean read the emerge output you sent to me.

gcc-config is very streamlined in this sense, it comes by default in
Gentoo (as far as I know), and I've used plenty of machines without
it, and it's very annoying to me to say the least.  It even told you
to do this.  Did you want it to change you USE flags for you too?
