------------------------------------------------------+---------------------
 boost/math/special_functions/next.hpp

 doesn't include

 boost/math/special_functions/trunc.hpp

 and hence I get linker errors when only including the former and using
 boost::math::float_advance:

 main.cpp
 --------


 #include <boost/math/special_functions/next.hpp>
 // including this prevents the linker error //#include
 <boost/math/special_functions/trunc.hpp>

 int main(int argc, char** argv)
 {
      double x = boost::math::float_advance(1.0,1);
      return 0;
 }
 reported by Jeffrey Hellrung and confirmed.

 Fix is to add #include trunc.hpp to next.hpp

 But this should have been detected?
