+* Remove dead code.
+
+  STRIP_DEAD_CODE = -Wl,-static -fvtable-gc -fdata-sections -ffunction-sections -Wl,--gc-sections -Wl,-s
+
+  -Wl,-static
+                Link against static libraries. Required for dead-code
+                elimination.
+
+  -fvtable-gc
+                C++ virtual method table instrumented with garbage collection
+                information for the linker.
+
+  -fdata-sections
+                Keeps data in separate data sections, so they can be discarded
+                if unused.
+
+  -ffunction-sections
+                Keeps funcitons in separate data sections, so they can be
+                discarded if unused.
+
+  -Wl,--gc-sections
+                Tell the linker to garbage collect and discard unused
+                sections.
+
+  -s
+                Strip the debug information, so as to make the code as small
+                as possible. (I presume that you'd want to do this in a
+                dead-code removal build.)
