More warnings with GCC-4.2.0

Hi All,
Finally managed to bypass the GCC-4.2.0 errors on asmsyms.h
(I am using the CVS tree and porting to an ARM platform, it is not
compilable directly)

I still have warnings
/usr/local/work/l4Ka/l4arm/pistachio/kernel/include/api/v4/thread.h:59:
warning: large integer implicitly truncated to unsigned type

and this is associated with
 static threadid_t anylocalthread()
    {
        threadid_t tid;
        tid.local.zero = 0;
        tid.local.id = (word_t) (-1UL);   >>>> WARNING
        return tid;
    }

Is there any clean solution to this warning?
