i'm not able compile new kernel

[Jiri "Kasi" Kastner <indy.j@worldonline.cz>]

I downloaded kernel source from ftp://ftp.linux.sgi.com/.../v2.3/ 
make menuconfig,
make dep,
this is OK, but when I try make zImage I always get this error output:

I would like to compile new kernel on indy (hardhat 5.1). Can anybody write to
me what is wrong? My indy is MIPS4600 (IP22), XL-8 bit graphics, vino, IndyCam,
soundcard.

Thanks
Jiri.
