这算那门子错误？

smego

编译时出现了这样的错误，
make CFLAGS="-D__KERNEL__ -I/usr/src/linux-2.4.24/include -Wall -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -O2 -fomit-frame-pointer -pipe -mpreferred-stack-boundary=2 -march=i386 " -C  kernel

打开这个文件看看，第一个错误发生在这里，
    210 static FASTCALL(void reschedule_idle(struct task_struct * p));
    211
    212 static void reschedule_idle(struct task_struct * p)
    213 {
    214 #ifdef CONFIG_SMP
    215   int this_cpu = smp_processor_id();
    216   struct task_struct *tsk, *target_tsk;
    217   int cpu, best_cpu, i, max_prio;
    218   cycles_t oldest_idle;
    219

按来说 这样没有什么问题呀 并没有重复定义，前一次只是声明而已。

我用的是debian下的gcc-3.4编译，大家看这是什么问题？是我的gcc不够新？

呵呵，估计是gcc太新了，而不是不够新

另外你的编译参数真多，尝试去掉一些限制看看，比如-Wstrict-prototypes

static和FASTCALL中间好像缺void，括号里面的void应该去掉
static void FASTCALL(reschedule_idle(struct task_struct * p));
