Hey all,

gcc6 uses std=gnu++14 as default (compared to std=gnu++98 up to gcc5.3)
[0]. This causes a lot of warnings during building gnuradio due to the
deprecated auto_ptr (unique_ptr is the way to go now) and gr-zeromq
fails building completely.

Probably the used c++ standard should be set in cmake?

I know that this is currently not a real bug. At the moment this is only
a problem on Arch Linux (repos updated last month on gcc6). Fyi, here is
the gcc development plan [1].
