+Subject: [PATCH] build: extend "extern C" block in header files
+Upstream: https://github.com/cddlib/cddlib/pull/46
+
+I am getting compile errors in sympol when I try to remove
+their extern "C" hack:
+
+	extern "C" {
+	#include <cddlib/cdd.h>
+	}
+
+Turns out this is because cdd's own extern C are not broad enough.
