Description
Some ratpoints tests fail on cygwin, e.g.:
sage -t "devel/sage/sage/libs/ratpoints.pyx" ********************************************************************** File "/home/wstein/sage-4.4.3/devel/sage/sage/libs/ratpoints.pyx", line 57: sage: for x,y,z in ratpoints([1..6], 200): print -Integer(1)*y**Integer(2) + Integer(1)*z**Integer(6) + Integer(2)*x*z**Integer(5) + Integer(3)*x**Integer(2)*z**Integer(4) + Integer(4)*x**Integer(3)*z**Integer(3) + Integer(5)*x**Integer(4)*z**Integer(2) + Integer(6)*x**Integer(5)*z Expected: 0 0 0 0 0 0 0 Got: 0 0 0
What happens when the same is done manually:
sage: from sage.libs.ratpoints import ratpoints sage: sage: for x,y,z in ratpoints([1..6], 200): ....: print -1*y^2 + 1*z^6 + 2*x*z^5 + 3*x^2*z^4 + 4*x^3*z^3 + 5*x^4*z^2 + 6*x^5*z ....: 0 0 0
So the problem is simply that less points are found. Sounds pretty serious...

But the same thing happens by hand. Why are all these tests passing on Cygwin?

This now passes, and when I do it by hand I do indeed get seven zeros. JP, if you can confirm this, then we can close this ticket as no longer valid.
