I looked at this once a while back, I replaced:

        continuation->ctx.uc_mcontext.sc_ar_bsp -
                __libc_ia64_register_backing_store_base;

with

        uint64_t i;

        __uc_get_ar_bsp(continuation->ctx.uc_mcontext, &i);
        i - __libc_ia64_register_backing_store_base;

I may have run into other issues after this because it doesn't look like
I ever did a complete guile build for IA64 HP-UX.
