We are testing 4.9 in the autobuilders. I rebuilt the pre-built
toolchains a few days ago. We had two gcc 4.8 toolchains, which I moved
to 4.9 toolchains. I always try to make sure we have a few "old"
toolchains, and at least one "bleeding edge" one, just to test more
configurations.

Also, we still have much older external toolchains: remember the recent
ICU breakage caused by ICU requiring gcc 4.8 ? If such breakage
occurred, it's because we do have toolchains with gcc's older than 4.8.

Best regards,

Thomas
