 Replying to [comment:8 vbraun]:

 I did exactly this. It compiled without a problem. However, there was a
 doctest failure when I ran {{{make ptest}}}:
 {{{

 Interestingly, this is precisely the same error (including the same
 output) as in #9310. Note that I now have two independent builds of
 sage-4.6.2.alpha3 on my machine, one in which this test passes and the
 other in which it fails.

 Anyhow, I think this doctest failure is unrelated. Your fix works
 perfectly, so I am willing to give it a positive review provided that you
 agree that the above failure is unrelated.
