sage -testall passes, but the test for hash(P) in
multi_polynomial_libsingular.pyx needs to be changed for 32-bit
machines since I don't have access to one.

sage: PolynomialRing(ZZ, 'x')
Univariate Polynomial Ring in x over Integer Ring
sage: PolynomialR

I agree with this (but the documentation should be very clear). It's
the same in Magma:
> Type(PolynomialRing(RationalField()));
RngUPol

Here is the culprit:
sage: type(PolynomialRing(ZZ, 1, 'x'))
while
sage: type(PolynomialRing(ZZ, 'x'))
I've created a ticket: http://www.sagetrac.org/sage_trac/ticket/764
