-if the user passes the <code>-fsized-deallocation</code> flag. The user must
-supply definitions of the sized deallocation functions, either by providing them
-explicitly or by using a C++ standard library that does. <code>libstdc++</code>
-added these functions in version 5.0, and <code>libc++</code> added them in
