I talked with Christoph earlier and he basically said that the
constant can just be bumped up without any ill effect (it would be
great if Tony Luck can confirm this).  So, it's an annoying thing and
in the long term removing would be a good idea but I don't think it's
anything major as long as it blows up during build not runtime.
