This rule is redundant: Make knows how to compile .c files into .o files
without your telling it.  It also knows that every .o file depends on the
corresponding .c file.  The only piece of knowledge you need to convey to
Make is that the .o files depend on the headers.  Here's how you do that:

$(OBJS): $(HEADS)

That's it!  Do NOT put any commands under this line, because this isn't a
rule, it's just a dependency description.
