+Subject: [PATCH] avoid race condition
+
+It's possible that the cxx-generate-packed-data.cc is compiled
+while the t/test-full.pb.h is being generated. This will result
+the following error.
+
+  DEBUG:	./t/test-full.pb.h:4:0: error: unterminated #ifndef
+  ./t/test-full.pb.h:4:0: error: unterminated #ifndef
+
+Add a dependency to avoid such problem.
