#1637: Dtypes should not use '=' in hashing
-----------------------------------+----------------------------------------
 Reporter:  pv                     |       Owner:  somebody
     Type:  defect                 |      Status:  new     
 Priority:  normal                 |   Milestone:  1.5.1   
Component:  numpy.core             |     Version:  1.5.0   
 Keywords:  byte order dtype hash  |  
-----------------------------------+----------------------------------------
 Dtypes with byteorder=='<' and byteorder=='=' should hash equal (on big-
 endian systems). This does not seem the case now:
 http://projects.scipy.org/scipy/ticket/1300

 Normally, it's not possible to create dtype objects with the native
 variant of '<' and '>' as byte order, as that is converted to '=' in
 PyArray_DescrConverter.

 However, they might appear from pickling, 3rd party extensions etc., so
 doing the right thing would be useful.
