- add --with-cdecimal flag to tests, monkeypatches cdecimal in - fix mssql/pyodbc.py to not use private '_int' accessor in decimal conversion routines - pyodbc version 2.1.8 is needed for cdecimal in any case as previous versions also called '_int', 2.1.8 adds the same string logic as our own dialect, so that logic is skipped for modern pyodbc version - make the imports for "Decimal" consistent across the whole lib. not sure yet how we should be importing "Decimal" or what the best way forward is that would allow a clean user-invoked swap of cdecimal; for now, added docs suggesting a global monkeypatch - the two decimal libs are not compatible with each other so any chance of mixing produces serious issues. adding adapters to DBAPIs tedious and adds in-python overhead. suggestions welcome on how we should be doing Decimal/cdecimal.
