For whom it concerns:

Hello!

Today i`ve tried to compile a linux-2.6.26-rc5-mm2 kernel obtained with the 
Ketchup tool.
 
It got halfway interupted with the following error messages:

CC [M] fs/xfs/support/debug.o

make[1]: *** [fs/quota.o] Error 1
make: *** [fs] Error 2

I have made 5 attempts to recompile the source with the same result.

Here is the output of the ver_linux script as i understand it may be helpfull:
