If that's the case, I'm having trouble seeing why it's worth our time to havethat unchecked "4.9" into the code. If the only time the "4.9" matters is whenwe bump the min GCC release, we can simply reverify all the version-dependentdiagnostics when that happens. That way, we don't need to put the "4.9" intothe source code now, which is a good thing because the "4.9" is probably wrongand it's confusing even if it's right.
