Follow-up Comment #6, patch #9549 (project octave):

@Marco: Yes, I understand that reasoning as well.  Pure mathematics doesn't
have a signed zero, it is an artifact of the implementation on computers. 
Given that we are trying to match pure math, it seems like we should have
expint (-0) == expint (0) == Inf as Matlab does.  In that case, we can close
this report.
