Try to add a system call but compilation error occured

[ahm_irf]

Hi,

I have tried to add a system call in Fedora Linux 6. I have attached a file where the steps are written
its URL is http://nd.edu/~ablaich/system_call_i...n_a_blaich.txt

During compilation of the kernel I got the following error.

Can any body help me or suggest me any solution.
