Subject: C++ PATCH to change default dialect to C++14

Authentication-results: sourceware.org; auth=none

I've been threatening to do this for a couple of months, and now that

the regressions are under control I think it's time. This patch changes

the default C++ dialect to C++14.

Tested x86_64-pc-linux-gnu, applying to trunk.
