#2017: On 32 bit, uintp and uint32 do not have the same hash

 Priority:  normal      |   Milestone:  Unscheduled
Component:  numpy.core  |     Version:  1.6.1

 >>> np.uintp
 numpy.uint32
 >>> np.dtype(np.uintp) == np.dtype(np.uint32)
 True
 >>> hash(np.dtype(np.uintp)) == hash(np.dtype(np.uint32))
 False

 This creates a problem for using dtypes as dict keys. Also, it seems that
 this bug is not present on 64 bit, where uintp and uint64 have the same
 hash.
