Milestone:  To Be Determined               |  Component:  random

 Compiling libs/random/test/test_non_central_chi_squared_distribution.cpp
 on Solaris 11.2 with Oracle Solaris Studio12.4 using -library=stlport4, we
 see the following error:
 "../boost/random/non_central_chi_squared_distribution.hpp", line 149:
 Error: The function "sqrt" must have a prototype.

 In file boost/random/non_central_chi_squared_distribution.hpp, the
 following change resolves the issue.
 diff ./non_central_chi_squared_distribution.hpp
 ./non_central_chi_squared_distribution.hpp_new

 <             RealType term1 = _z + sqrt(_param.lambda());
 ---
 >             RealType term1 = _z + std::sqrt(_param.lambda());
