Hi,
I just finished to try this procedure (with some more step added) to
cross-compile the kernel on my PC, but it does not work.
I did all the step up to the distclean, then I modify the Makefile
(according to Matt Porter instructions), I copied the
mvme2600.config.nfsroot as .config and did make oldconfig.
Everything up to here went fine, without any error or warning.
Then I did make dep and make clean (always using the Matt Porter
instruction) and the make zImage, at the end the error was this:

powerpc-linux-gcc -D__KERNEL__ -I/home/ppc/linux/include -Wall
-Wstrict-prototypes -O2 -fomit-frame-pointer -D__powerpc__ -fsigned-char
-msoft-float -pipe -fno-builtin -ffixed-r2 -Wno-uninitialized -mmultiple
-mstring -mcpu=603e -D__powerpc__ -msoft-float -pipe -fno-builtin -Wall
-mmultiple -mstring -I../boot -I/home/ppc/linux -D__KERNEL__ -O2
-fomit-frame-pointer -mrelocatable -ffixed-r13 -D__BOOT__ -DDEBUG  -c -o
zlib.o zlib.c
zlib.c:83: string.h: No such file or directory
zlib.c: In function `inflate_blocks':
zlib.c:878: warning: implicit declaration of function `memcpy'
make[1]: *** [zlib.o] Error 1
make[1]: Leaving directory `/home/ppc/linux/arch/ppc/prepboot'
make: *** [zImage] Error 2

I'm a little bit worried about the -mcpu=603e switch but I don't think
this can be relate to the error. 
I looked inside the kernel tree and there are many of these file inside:

/home/ppc/linux/include/asm-alpha/string.h
/home/ppc/linux/include/asm-arm/string.h
/home/ppc/linux/include/asm-i386/string.h
/home/ppc/linux/include/asm-m68k/string.h
/home/ppc/linux/include/asm-mips/string.h
/home/ppc/linux/include/asm-ppc/string.h
/home/ppc/linux/include/asm-sparc/string.h
/home/ppc/linux/include/asm-sparc64/string.h
/home/ppc/linux/include/linux/string.h


The code where the (1st) error come is:
         /* functions */

#include <string.h>
#define zmemcpy memcpy
#define zmemzero(dest, len)     memset(dest, 0, len)

and it seems absolutely normal to me.

The cross compiler was build installing egcs 1.1.2 and the glibc-2.1
over a Redhat 5.2, and then using the Matt Porter instruction (with the
exception of a newer version of binutils, because that one was not
accepted in the egcs upgrade).

If you have any idea about how to solve this I'll be happy.
Thanks to everybody
