Description
In file boost/functional/hash/hash.hpp line 438
I compiled in Visual Studio 2015 with /std:c++latest option. Compiler reports that the unary_function is not a member of "std".
Here is the cpp doc about std::unary_function, std::unary_function is deprecated in C++11 and removed in C++17

Sorry, I forgot to close this ticket. It's fixed in master, so it should be in Boost 1.64.0.

I am hitting this on 1.63.0 too. Even a unofficial patch to work around the problem would help a lot.

The appropriate commit is here:
https://github.com/boostorg/functional/commit/281e11b2923249869cce3131a415118bb9e2f1e1
But you could probably just delete all references to the problem classes. I think there's also a Visual Studio option you can use.
This issue is still in Boost 1.63.0. Any ETA for a fix?
Thx! Jean
