I think this is just out of date.
Indeed. I had a patch to fix this in my local tree since January, which
I have now finally pushed.

Hi Jason,
Today, the bootstrap requirement is C++11 (see configure.ac [1]).
Most of the people in this thread seemed to agree around mid-September
with changing the bootstrap requirements from C++11 to C++14.
What was the final decision (if any) ?
Can the bootstrap requirement be increased to C++14 ?
