That call is already llabs() in version 6.1, so it should be OK for 6.0
also.

But, thinking about it, the type of intgr_t is configuration-dependent.
To assume it is specifically either (long) or (long long) might cause the
equivalent
compiler complaint for someone else.
I think the problem is avoidable by changing this to
        intgr_t tmag = (a.v.int_val < 0) ? -a.v.int_val : a.v.int_val;

thanks,
