Follow-up Comment #1, bug #38142 (project octave):
I'm not sure build failures with C++11 are a bug.
As an annoying thing that we've discussed on the mailing list, C++11
apparently gets rid of the std::pow(double,int) specialisation that gives you
e.g. pow(1.5,2) exactly, without round-off error.
The tests that fail here seem to be related to std::pow, and I think
pow(1.5,2) should not have round-off error. Are other library implementors
besides GNU doing this?
