gcc (GCC) 4.0.1 (Debian 4.0.1-2) g++ (GCC) 4.0.1 (Debian 4.0.1-2) GNU Make 3.80 automake (GNU automake) 1.4-p6
This is your problem, the new versions of GCC wont compile the current Kernel sources in Debian. You can
1. Change the top level MAKEFILE in the source directory to point at the previous GCC versions 2. Temporarily change the symlinks in /usr/bin for gcc/g++ etc to point at the old version.
I'm a bit of a noob and couldn't get 1. to work so used 2. quite successfully.
