Compilation error on the latest mtd code

When compiling the latest mtd code with the kernel linuxppc_2_4_devel checked out from bk://ppc.bkbits.net, I encountered the following error. This kind of error seems to be caused by some special control character in a text file. So I used 'dos2unix' to convert all header files. But it didn't solve the error. Any hints? Thank you very much.
