Milestone:  To Be Determined    |  Component:  multiprecision
  Version:  Boost 1.57.0        |   Severity:  Problem

--------------------------------+----------------------------
 Compiling the following code (g++ 4.8.3 with -fext-numeric-literals)
 gives

 fmatest.cpp:9:16: error: ‘fma’ is not a member of ‘boost::math’

 {{{
 #include <iostream>

 int main () {
   typedef boost::multiprecision::float128 real;
   real a = 10, b = 1/a, c = -1;
   std::cout << boost::math::fma(a, b, c) << " " << a * b + c << "\n";
