linux下编程用 编译软件

				extern void abort(void);				extern void exit(int);								struct baz { int a, b, c; };								struct baz *c;								void bar(int b)				{				  if (c->a != 1 || c->b != 2 || c->c != 3 || b != 4)				    abort();				}								void foo(struct baz a, int b)				{				  c = &a;				  bar(b);				}								int main()				{				  struct baz a;				  a.a = 1;				  a.b = 2;				  a.c = 3;				  foo(a, 4);				  exit(0);				}
