Description: This PR, based on a patch by Serhiy Storchaka, fixes the issues with signed zeros identified in http://bugs.python.org/issue29602: given a class class A(object) implementing __complex__, complex(A()) ignored the sign of a negative zero in the imaginary part given a subclass class C(complex), construction of a C instance from a complex instance also ignored the sign of a negative zero in the imaginary part.
