Hello Everyone.

After having no luck in binary upgrading my qube2 to the new current and 
having no experiences in debugging a kernel or how to do this over a 
serial port (sorry), I just reinstalled 3.99.17 with the restore cd and 
got me the src tar balls.

I know that 3.99.17 isn't stable, but I knew it wouldn't crash in the 
first 12h of compiling. I thought this would give me enough time to 
build the toolchain and a new kernel and then reboot with this kernel to 
build the userland. That was my theory.
I had no trouble building the toolchain, but compiling the kernle always 
fails (I tried it with the GENERIC and the INSTALL config). It alway 
fails at this point:

------------------------------------------------------

I have no clue if I have made a mistake or what is wrong. Can somebody 
give me a hint what I can try to make it compile?

Thanks a lot for all the support :)
