See http://stackoverflow.com/questions/34449254/how-is-argument-dependent-lookup-looking-here

I found that code that has worked OK on previous versions of Boost (and does not have this 
issues with 1.59) is getting unexpected ambiguities in 1.60.  Using boost::totally_ordered 
et al. (even as a private base) appears to be polluting the namespace in which the client 
class appears.

Something like this:

     class C : boost::totally_ordered<C> { ⋯ } ;

     using std::make_shared;

     â‹®
         auto p= make_shared<C>(args);

this complains that it finds boost::make_shared via argument-dependent lookup, as well as 
the expected std::make_shared.
