That's why there's a bug report. > Otherwise please give a short comment to this bug report explaining why this > can not or should not be fixed. Of course it should be fixed, that's why there's a bug report and it hasn't been closed. But we have lots of bugs and finite resources. > Especially if giving C++14 as default ... As I said above, it's not actually clear if this is required by C++11 and C++14. The function sqrtl is not mentioned at all in the C++14 standard. It's definitely required by C++17, but that isn't enabled by default.
