[SciPy-dev] dtype name coverage

Hi,

I was going through some old numstar code, trying to get it to work with
scipy core, and I was initially frustrated by the lack of "UInt8" in
scipy, because it's the only name for this dtype shared between numarray
and Numeric. To investigate the situation further, I wrote a little
script (attached), which I think should be used to add a few more names
to the scipy namespace in the name of backwards compatibility with
numstar.  Here's the output on my machine:

                      scipy       Numeric      numarray
        UInt8             -             +             +
 UnsignedInt8             +             +             -
        uint8             +             -             +

       UInt16             -             +             +
UnsignedInt16             +             +             -
       uint16             +             -             +

       UInt32             -             +             +
UnsignedInt32             -             +             -
