Follow-up Comment #3, bug #49091 (project octave):

I checked and __have_feature__ reports that I am using the std library
version.  So, that kind of sucks.  The std library is less accurate than
direct computation on Windows machines.

Do we want to change the library or the test?  We could certainly add to the

      return std::acosh (x);
      return log (x + sqrt (x + 1.0) * sqrt (x - 1.0));

The second option is to increase the tolerance of the test.
