We already have some support for checking the compiler version. I
wonder if the plugins could add themselves to the version name in
there somehow..

But I don't think it's a big deal, and I won't worry about it. I do
hope we can deprecate the plugins some day, it has always made me very
nervous to have random code at that level.
