struct user.u_ar0 is defined to contain a pointer offset on all architectures in which it is defined (all architectures which define an a.out format except SPARC.) However, it has a pointer type in the headers, which is pointless -- <asm/user.h> is not exported to userspace, and it just makes the code messy. Redefine the field as "unsigned long" (which is the same size as a pointer on all Linux architectures) and change the setting code to user offsetof() instead of hand-coded arithmetic.
