PyTables test suite raises a DeprecationWaring when this combination is made in a NpyIter_AdvancedNew call and NumPy 1.8 is used. Here it is an example:

$ python tables/tests/test_all.py
[clip]
test_multiprocess (tables.tests.test_basics.BloscSubprocess) ... /home/faltet/software/PyTables-Francesc/tables/conditions.py:456: DeprecationWarning: using `oa_ndim == 0` when `op_axes` is NULL is deprecated. Use `oa_ndim == -1` or the MultiNew iterator for NumPy <1.8 compatibility
  return func(*args)

The information here: numpy/numpy#3104 seems relevant.

@mwiebe could you confirm that the fix above makes sense? In particular, the PyTables tests passes completely without the if lines in the fix, but I thought it would not hurt either.
