Yes, and I agree with Ingo on this, you can require flex and bison to
build this code, I have no problem with that.

It's the "you must build with this specific version that is not possible
for your distro otherwise the build will break" side affect of this that
I do have a problem with :)

Why can't we turn off "build error on warning" for just these generated
files?

thanks,
