Compilation problem

[PUCCETTI Armand <armand.puccetti@cea.fr>]

When compiling XEN 3.0.3 (KERNELS = linux-2.6-xen0 linux-2.6-xenU) with 
Linux kernel 2.6.16.29 or 2.6.26.35
and with gcc 4.1, I stumble over the following compilation error:

make[3]: entrant dans le répertoire « 
.../xen-3.0.3_0-src/linux-2.6.16.35-xen0 »
CHK include/linux/version.h
CC [M] net/ipv4/netfilter/ip_conntrack_proto_tcp.o
In file included from net/ipv4/netfilter/ip_conntrack_proto_tcp.c:33:

named ‘tso_segs’

make[5]: *** [net/ipv4/netfilter] Erreur 2
make[4]: *** [net/ipv4] Erreur 2
make[3]: *** [net] Erreur 2

Compilation command is:

$ make dist CC=gcc-4.1 verbose=y debug=y perfc=y debugger=y
and with extra CFLAGS option -fno-stack-protector.

It appears to be the same error with kernel 2.6.17.10.

Any advice?

thx
