Not only that, the version in ioctl.h has several problems.

1) ioctl(fd, code, 1) and ioctl(fd, code, (void *)1) may have
   different ABI. eg on a 64bit platform.

2) Some architectures use different calling conventions for
   varargs functions (eg passing everything on the stack, instead
   of using registers).
