+	parse-datetime: fix generated paths for coverage files
+	* modules/parse-datetime: Adjust the paths for parse-datetime.y
+	within parse-datetime.c, so that gcc generates appropriate .gcno
+	files, allowing lcov to proceed without error.  Previously it
+	would error trying to find "lib/lib/parse-datetime.y".
