libstdc++: Only define __any_input_iterator for C++20 Currently this new concept will get defined for -std=c++17 -fconcepts but as it uses std::input_iterator, which is new in C++20, that won't work. Guard it with __cpp_lib_concepts as well as __cpp_concepts. libstdc++-v3/ChangeLog: * include/bits/stl_iterator_base_types.h (__any_input_iterator): Only define when __cpp_lib_concepts is defined.
