Hi,

as the subject says, the array_* comparison functions currently do not operate 
on structured/record arrays. Pull request 
https://github.com/numpy/numpy/pull/146
implements these comparisons.

There are two commits, differing in their interpretation whether two 
arrays with different field names, but identical data, are equivalent; i.e.

        res = array_equiv(array((1,2), dtype=[('i','i4'),('v','f8')]),
                          array((1,2), dtype=[('n','i4'),('f','f8')]))

is True in the current HEAD, but False in its parent.
Feedback and additional comments are invited. 

Cheers,
						Derek
