Subject: Stop using the now deprecated and useless std::binary_function
X-Git-Tag: auth-4.6.1~2^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F11235%2Fhead;p=thirdparty%2Fpdns.git

Stop using the now deprecated and useless std::binary_function

It is no longer needed since the types can now be automatically
deduced, has been deprecated in C++11 and removed in C++17.

(cherry picked from commit 7587bcbea8a9cb3058cb2e6d7f6a2597494b6713)
