Makefile中自动生成依赖关系？

[shelf]

我看过一些文档，说自动生成依赖关系（目标文件和头文件），可以采用如下模式规则：
%.d: %.c

$(CC) -M $(CPPFLAGS) $< > $@.$$$$; \

sed 's,\($*\)\.o[ :]*,\1.o $@ : ,g' < $@.$$$$ > $@; \

rm -f $@.$$$$

sources = foo.c bar.c

sinclude $(sources:.c=.d)

我不知道是否将这加入到MAKEFILE中，我尝试加进去，但是没有任何反应
请问要自动生成头文件的依赖关系，MAKEFILE中到底如何写？
请教！！

把俺N年前写的makefile弄出来了：
Make.rules:

注意
make文件中的第一个目标项是make的默认目标

我按照这个模式写的为什么不能自动产生依赖关系呢？
能给个更详尽的解释吗？
