--- Comment #9 from Dilawar Singh <dilawar.s.rajput at gmail dot com> --- The snippet I sent you (in url filed) is a part of large project which compiles fine on Ubuntu-server (gcc4.7.x, I am not sure about x). I will confirm it later once I login onto server again. Once I change `isnan` to `std::isnan` in my project, it compiles fine with my g++-4.8.1.
