<string.h> defines strerror and other identifiers in the global
namespace, and may optionally define them in the std namespace, while
<cstring> defines them in the std namespace and may optionally define
them in the global namespace.

(I dislike this, but that's the way the language specifies it.)

Also, the <*.h> C headers are deprecated as of C++17.
