Prob to compile Kernel on mpc860.

[Christophe.LINDHEIMER at fr.thalesgroup.com]

Hi .

prob 1 :
I am trying to compile the linuxppc_2_4_devel_2.4_20-2002_12_04 from Denx.
As I need debug, I replace -O2 by -g in the Makefile.
The kernel doesn't link anymore :[

prob 2 :
Using linux2.4.22 from kernel.org.
I apply the patch for powerpc
the kernel doesn't compile.
Prob with stdarg.h that doesn't exist ( in sched.c )
