Fine with me as well. I took 2013 because I did not want to diverge too far
from your proposal;-)

It turned out that it was too difficult to retain the stuff for some
hypothetical future C++14 checks. I will commit the attached unless nobody
objects. This is simply the unconditional use of C++11. After this patch it
would be possible to get rid of parts of the included boost already.
