Kernel Compiling

[Michael J. E. Swift]

Hi,
     I'm trying to enable video4linux and firewire support
on my machine here, but when i go to build the kernel, it
crashes.  The following is the last few lines (where it
broke), so if anyone could give me some pointers, I would
appreciate it.  I'm working with 2.4.20-8d from the install cd.
