Resourceful Code Reuse: Should have depend: example dependent on sources (page 19)

I didn’t know about the -MM switch in the c compiler - that’s really useful!

In the Makefile example, on line 15, it should have the depend target have prerequisites $(SRCS) so that if the dependencies in the code changes, the depend file is rebuilt and make can see the new dependencies. That could be really confusing for someone if they didn’t have that in place.

depend: $(SRCS)
        $(CC) -MM $(SRCS) > depend

The clean target should probably remove the depend file as well.
