[Cython] "relaxed_strides" test broken with NumPy 1.8

[Stefan Behnel]

Hi,

I enabled the NumPy build for our Py3.3 test runs and while I was at it, I
got it to use the latest NumPy release 1.8. This made one of the tests fail:

"""
    Traceback (most recent call last):
      File ".../doctest.py", line 1313, in __run
        compileflags, 1), test.globs)
      File "<doctest relaxed_strides.__test__.test_one_sized (line
29)[3]>", line 1, in <module>
        test_one_sized(a)[0]
      File "relaxed_strides.pyx", line 38, in

According to the comments in the test file and the corresponding NumPy pull
request, this seems to be somewhat expected.

https://github.com/numpy/numpy/pull/3162

Does someone know enough about this to figure out what to do?
