I am on Fedora 25 which also uses gcc 6.3.1. The default standard for
6.3.1 is C++14. The output from configure should contain these lines:

  Default C++ compiler:      g++   
  C++98 compiler:            g++ -std=gnu++98 
  C++11 compiler:            g++ -std=gnu++11 
  C++14 compiler:            g++  
  C++17 compiler:              

Please check.
