|  4.4 Suffix rules 
To simplify a `Makefile', there is a special kind of rule syntax
known as a suffix rule.  This is a wildcard pattern that can
match targets.  Our first `Makefile' used some.  Here is one:
 
 |  | 
 .c.o:
	$(CC) $(CFLAGS) -c $< -o $@
 | 
 
Unless a more specific rule matches the target being sought, this rule
will match any target that ends in `.o'.  These files are said to
always be dependent on `.c'.  With some background material now
presented, let's take a look at these tools in use.
