Well, I had never tried 4.9.3, and I'd been using 4.6 without problems
for some time, so keeping 4.6 seemed like the safe way to go.  I still
don't understand what broke 4.6.

I built a few binary gcc packages on different Gentoo installs using
quickpkg.  The first couple didn't work, but I eventually found a
machine whose gcc binaries will run on my broken box.  I've now got a
binary install of gcc-4.9.3 that seems to be working.  It's been
building gcc 4.9.3 for about 15 minutes now (building it with 4.6
would fail within 15-20 seconds).

Tinderbox's owner pulled the plug on it a couple years ago. AFAIR, it
didn't have anything to do with the website reort.
