Comment (by johnmaddock):

 The simplest solution is to define
 BOOST_MATH_NO_LONG_DOUBLE_MATH_FUNCTIONS which will disable all long
 double support.  That define would go in boost/math/tools/config.hpp near
 the top.

 The problem with a "double double" type is that not only is it not IEEE
 conforming, but it's basically impossible to reason about it's behavior in
 any kind of sensible way.  As none of us have any access to a system that
 uses such a type we've never tried to support it: if you wanted to try and
 patch Boost to support that type I have some ideas where to start, but it
 wouldn't be a small job I suspect :-(
