There may be.    I took Robert's git branch and tried to re-base it.   
But, I'm a git neophyte and didn't know what I was doing.   I tried to  
eliminate the most obvious cases where is trunk was out-of-date, but  
obviously missed some.

Thanks for checking.  I don't want to stomp on your work, but I don't  
know what you mean by cleaning up arraytypes?

I am hoping to get the datetime changes merged to trunk by the end of  
the month.   There are a couple of potential issues that may slow that  
down because of the change to the PyArray_Descr structure (we need to  
add a metadata object at the end).

We may need to bump up the version number of NumPy to encourage C- 
extensions to re-compile, but I think it will work without that.
