helloworld 驱动程序编译的问题？

一个简单的驱动程序例子，怎么编译都不行，请指教。源代码和makefile 如下:
我的机器: winxp +vmware

/*                                                                                                           

  *   $Id:   hello.c,v   1.5   2004/10/26   03:32:21   corbet   Exp   $   

  */                                                                                                         

#include   <linux/init.h> 

#include   <linux/module.h> 

MODULE_LICENSE( "Dual   BSD/GPL "); 



static   int   hello_init(void) 

{ 

printk(KERN_ALERT   "Hello,   world\n "); 

return   0; 

} 



static   void   hello_exit(void) 

{ 

printk(KERN_ALERT   "Goodbye,   cruel   world\n "); 

} 



module_init(hello_init); 

module_exit(hello_exit); 

makefile:

ifeq ($(KERNELRELEASE),)

KDIR ?= /lib/modules/$(shell uname -r)/build 

PWD  := $(shell pwd) 

modules:

	$(MAKE) -C $(KDIR) M=$(PWD) modules

modules_install:

	$(MAKE) -C $(KDIR) M=$(PWD) modules_install 

clean: 

	rm -rf *.ko *.o *.mod.c 

.PHONY:modules modules_install clean

else

	obj-m := hello.o 

endif

出错信息如下：
