I've applied the patch (as you've surely noticed, Vladimir).

However, I am beginning to think that it is best to fix sqrfree_yun such 
that no external workarounds are necessary.

It's a little bit tricky: The sign seems to get lost in the content part 
of the input polynomial. (Remember that it may itself be a polynomial in 
other variables.) And the unit part is not deterministic for 
multivariate polynomials. I'm working on a patch.
