+ * makefile and forcibly updated every time make is run. Including it
+ * here causes automake to track it as a dependency, which will cause
+ * version.o to be rebuilt too.
+ *
+ * The space between # and include causes mkfiles.pl's dependency
+ * scanner (for all other makefile types) to ignore this include,
+ * which is correct because only the automake makefile passes
+ * -DINCLUDE_EMPTY_H to enable it.
