Description
If you try to open shape files that have duplicate column names, you'll get an error. Autodesk Mapguide Studio gives me a "Read Schema Failed" message. Autodesk's Map 2008 (which supposedly used FDO for importing shape files) says it's "Invalid Data". ESRI's ArcView opens it them just fine, as did prior versions of Autocad that did not use the FDO provider.

I have attached a patch which renames the columns as part of the read process if duplicate column names are detected. The column names are truncated and a numeric value is appended to the column name. If no duplicates are detected, the column names remain unchanged.
