Appearantly we forgot to officially deprecate MPX in GCC 7 changes.html.
The following adds the missing note.
Ok?
Thanks,
Richard.

I don't recall deprecating MPX. I do recall deprecating Cilk+.
There's certainly folks at Intel fixing MPX related issues for GCC.

Ok, maybe I misremember.

Sure. But bootstrap with MPX is broken since forever and I don't see
anybody using the feature -- plus it's maintainance burden is quite
higher than Cilk+.
Well. Let's keep it in mind then for GCC 8 deprecation.
Disclaimer: I was asked if we can remove it right now because of its
impact on cgraph code.
Richard.
