That won=E2=80=99t fix the issue, because base (as you can see from the =
passed compile command) is compiled with -Wsystem-headers, which issues =
warnings even in system headers.  This is increasingly unhelpful and =
must, for example, be turned off when compiling anything written in C++ =
because of warnings in libc++ headers.
