Let's not limit this to C++14 mode; most DRs apply to earlier
standards as well.


curiously opening it up leads to some test failures related to
determining the exception specifier for implicit ctors and dtors.  Not
had time to investigate that yet ...


If C++98 mode is problematic, we can limit this to C++11 and up.
