ODBC Driver int8 Patch

Hi,

It was suggested that I post this patch here as no notice was taken of it
when posted to interfaces!

This fixes problems with int8 columns which are reported by the driver as
SQL_BIGINT rather than SQL_CHAR as per the ODBC v2 spec. Specifically, I
have had problems with MS ADO - any queries that contain an int8 column in
the resultset will *always* return an empty recordset.

Regards,

Dave.
