However, many compilers fail to integrate language linkage into the function's type, despite the normative requirement to do so in the C++ Standard. For instance, GCC 6.1.0, Clang 3.9, and Microsoft Visual Studio 2015 all consider the following code snippet to be ill-formed due to a redefinition of f() rather than a well-formed overload of f().
