+Some tips from Cody:
+
+This entry relies on specific compiler warnings. With gcc it will look something

+lush.c:40: warning: "f" redefined

+```
+
+Now one can use `sed` to get the `warning:` line correct but there is more to it
+than that. For instance this is what it looks like with clang:
+
+```
+lush.c:40:9: warning: 'f' macro redefined [-Wmacro-redefined]
+#define f 001:
+        ^
+lush.c:1:9: note: previous definition is here

+        ^
+lush.c:42:9: warning: 'f' macro redefined [-Wmacro-redefined]
+#define f 100:
+        ^
+lush.c:40:9: note: previous definition is here
+#define f 001:
+        ^
+```
+
+As you might see the part under the `warning:` line is different.
+
+Can you help us?
