Error compiling kernel 2.4.26 + openMosix patches in x86_64

Hi all:

Mi name is Carlos and i am new in this list and openMosix.

I'm currently building an openMosix cluster using 8 machines with dual Intel 
Xeon EM86T (x86_64 architecture) dual core.
I installed centos 3.7 x86_64 (kernel 2.4.21) and I downloaded kernel 2.4.26 
sources and oM patches for that kernel.

Apply patches (no problem here), do "make menuconfig" and "make dep"  and then 
compilation fails with this error:

gcc -D__KERNEL__ -I/usr/src/linux-2.4.26/include -Wall -Wstrict-prototypes 
-Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer 
-mno-red-zone -mcmodel=kernel -pipe -fno-reorder-blocks -finline-limit=2000

Gcc version is 3.2.3 20030502 (Red Hat Linux 3.2.3-54)

Can someone help me?

Thanks a lot
