#10750: bad interaction between ublas, float128 and std::complex
------------------------------+---------------------
 Reporter:  vbeffara@…        |      Owner:  guwi17
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  uBLAS
  Version:  Boost 1.57.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+---------------------
 The following code fails to compile:

 {{{
 #include <boost/multiprecision/float128.hpp>
 #include <boost/numeric/ublas/lu.hpp>

 using boost::multiprecision::float128;

 int main () {
         boost::numeric::ublas::matrix <std::complex<float128>> A(1,1);
         lu_factorize(A);
 }
 }}}

 (on OSX 10.10 using g++-4.9 -fext-numeric-literals -lquadmath), I am
 getting a huge complaint about missing `operator<` at
 `numeric/ublas/detail/matrix_assign.hpp:33:35`. Things work perfectly with
 a matrix of float128, or a matrix of std::complex<double>. And other
 operations work with std::complex<float128>.

 Is std::complex<float128> supposed to work?
