Hi Barend,

Is it possible to know what/where was the patch for this ? I'm trying to move to TTMath instead of double because I'm having precision problems. 
But I cannot get it to compile because of abs.

I get errors such as:

boost/geometry/algorithms/detail/overlay/assign_parents.hpp:80: error: cannot convert ?ttmath::Big<1ul, 32ul>? to ?int? for argument ?1? to ?int abs(int)?
boost/geometry/strategies/cartesian/cart_intersect.hpp:350: error: cannot convert ?ttmath::Big<1ul, 32ul>? to ?int? for argument ?1? to ?int abs(int)?

Thanks,
-v
