2.4.20 scsi module build error?

I'm running on a Red Hat 8.0 system. I downloaded 2.4.20 kernel sources from www.kernel.org and proceeded to build the kernel.

While "making modules", I get this error:

make[2]: Entering directory `/usr/src/linux-2.4.20/drivers/scsi'

Thanks for info on what's going on.

Best regards,
