Problem on building the kernel 2.2.18 with MTD sc520 processor

[data]

Hi,

I would like to put the embedded linux into the sc520cdp processor
board. I follow the document The Linux MTD, JIFFS HOWTO to build the
kernel 2.2.18 with the patch MTD 2.2.18. During the compiling process, I
have encountered                  the following problem. Have anybody
come across similar problem before? If you do, could you please give me
a hand?
The followings are the installation log for the kernel when compiling
the driver MTD stuffs and I hope you can help me to sort out the
problem.

Thanks and regards,

Jimmy Chun
