-//                optimized standard library doesn't actually use *any* symbols
-//                from this library. Everything is inlined and optimized away.

-//                To get around this for now, we define a dummy symbol which
-//                will never get inlined so the stdlib can call it. The stdlib's
-//                reference to this symbol will cause this library's object file
-//                to get linked in to libstd successfully (the linker won't
