[PATCH v4 0/4] MR377: ci: Compile with -Werror.

[Giovanni Mascellani (＠giomasce)]

Manually disable some warnings that are currently emitted. Eventually
the warnings should be solved and -Werror should remain alone.

--
  v4: demos: Do not trigger -Wmissing-prototypes for wmain().
      vkd3d: Use CONST_VTABLE.
