The main difference between GCC 6 and the previous version for C++ is:

  The default mode for C++ is now -std=gnu++14 instead of -std=gnu++98.

(from, as incompatible changes
have been introduced in the new C++ standard.

This seems to be the cause of the failure here. One simple solution,
IMHO, is to switch back to -std=gnu++98. This is what the attached
patch does. I was not sure where to put -std=gnu++98, but with what
I did, it applies only to GCC, not to clang. So, I suppose that this
is what is expected. On my machine, ceph builds without any error
with this patch, but I have not tested the behavior when installed
(I don't see why there would be any new problem).

I don't think it would be worth to try to make this version C++14
compliant while there is a new version upstream (see the package in
experimental, for instance).
