   In practice, we might want to write the rule in a somewhat more 
complicated manner to handle unanticipated situations.  We would do
this:                        
                        
     .PHONY : clean                        
     clean :                        
             -rm edit $(objects)                        
                        
This prevents `make' from getting confused by an actual file called 
`clean' and causes it to continue in spite of errors from `rm'.  (See 
*note Phony Targets::, and *note Errors in Recipes: Errors.)                        

在实践中，我们也许想要写一个有点复杂的规则去处理未预料的各种情况。我们应当这样作：

      .PHONY :  clean

      clean     :  

                    -rm  edit  $(objects)

这可以防止 make 发现一个名字为clean 的文件的时候产生歧义。可以让它不至于产生错误而可以继续运行。 (*note Phony Targets::,  *note Errors in Recipes: Errors.)
