Comment (by faltet):

 Confirmed that arctanh works correctly now on Windows and MSVC9:

 Python 2.6 (r26:66721, Oct  2 2008, 11:35:03) [MSC v.1500 32 bit (Intel)]
 on win
 Type "help", "copyright", "credits" or "license" for more information.
 >>> import numpy
 >>> numpy.__version__
 >>> numpy.arctanh(1.)
 >>> numpy.arctanh(-1.)

 May I suggest that you explicitly put the revision where you fixed things?
 Something like r6115 would do.  Also, it would be nice if in the commits,
 you can refer to the ticket that the commit is addressed to (if any).
 This proves to be specially useful when, in the future, somebody is
 revising the ticket and wants to check the affected revisions or vice
