I've just filed one so the issue is known: 
https://svn.boost.org/trac/boost/ticket/11193

No that ship has sailed I'm afraid.

Embarrassingly I didn't realise that page existed - I'll try and find 
out what needs to be done to get a patch on there - although in some 
ways Github may replace this?

I guess check for boost-1.59 in boost/version.hpp - of that's a way off 
yet :(

Here's the patch on Github: 
https://github.com/boostorg/multiprecision/commit/c36e15bd292d3a6aa97091f4eec80e9f2f1b58d8

HTH, John.
