Fix for issue #45 on Google Code

https://code.google.com/p/pypyodbc/issues/detail?id=45

I'm not entirely sure why this fixes my issue but it does. I don't  have anything setup to test the other DBs, so I wasn't able to do that to make sure it doesn't screw something else up.

But this does run on both Ubuntu 14.04 under Python 3.4.2 and unixODBC and the db2 iSeriesAccess driver, as well as Python 3.4.0 and Windows' ODBC connection.
