Does anybody have an idea why the following code fails in the 2.6.21.7 Fedora 8 XEN kernel but not in 2.6.18.8-xen ?

The code is:

#include <linux/autoconf.h>
#include <linux/version.h>

int main() {
if (LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,0)) {
return 0;
} else {
return 1;
}
}

int main() {

} else {

}
}
emre@xenroot:/d/nvidia/nvidia-source-100.14.19-x86_64-xen$
Due to this, the whole nvidia driver compilation is failing even though it works on 2.6.18.8-xen dom0 kernel.
Any ideas on what's missing in the 2.6.21.7 sources?
Thanks a lot,
