Here is a patch to the libstdc++ docs re constexpr additions. They reflect the latest macro assignments AFAICT.

Constexpr interator reqs are implemented in 9.1, the rest for 10.1.

Ok?

Should I bother adding the Constexpr interator requirements to the gcc-9 branch docs?

Yes please, it would be good to have that part in the gcc-9 docs. No
need to regen the HTML on the branch at this time though.

Thanks

Ok,

I committed the attached for gcc-9.
