Comment (by Diego Barrios Romero <eldruin@…>):

 This also affects boost 1.62 which cannot be compiled with VS2015
 (MSVC14). I attached a patch with an ugly workaround.

 It adds a static instance of the param_not_found structure. A reference to
 this "singleton" object will be returned if necessary.
 As the structure itself is empty, wrong code could not do much with it.
 Furthermore, I imagine the whole param_not_found is just a construct to
 get the whole named-parameter system to work and the actual object
 returned will never be used in this case.

 I would be happy if someone reports a nicer solution.
 I would also be happy to submit this as a PR in github if you want.
