libstdc++6-devel-gcc10-10.2.1+git1030 on openSUSE Tumbleweed does not know std::cosl(). Is it really in the standard? --Tvogel (talk) 04:27, 1 March 2021 (PST)

-f and -l variants are present in the C++ standard library and namespace std since C++11 (which references to C99). See also P0175R1 which in contains editorial changes only intendedly (unintended changes are reverted via LWG3051). libstdc++'s <cmath> is buggy, while libc++'s and MSVC STL's provide -f and -l variants in namespace std. --Fruderica (talk) 05:50, 1 March 2021 (PST)

Thank you! I filed a request here GCC Bugzilla – Bug 99338. --Tvogel (talk) 01:19, 2 March 2021 (PST)
