+Subject: [PATCH] sdksyms.sh: Make sdksyms.sh work with gcc5.
+
+gcc5's cpp inserts patterns like this:
+
+extern
+      __attribute__((visibility("default")))
+                int WaitForSomething(int *
+    );
+
+This patch make sdksyms.sh work with this. Note my awk skills are weak, so
+there likely is a better way to deal with this.
