 which has a special line in the kernel makefile:

 A few more lines makes sure `version.c` is always recompiled if any
 other part of the kernel is:
 
-	kernel: $(kernel_objects)
-		rm -f version.o
-		$(MAKE) version.o
-		$(LINK)
+    :::make
+    kernel: $(kernel_objects)
+        rm -f version.o
+        $(MAKE) version.o
+        $(LINK)
 
 Obviously, this is a bit simplified. But not much. I might make a post
 about my makefiles some day...
