        * db-oracle/make9.sh: add makefile for building with Oracle 9 client
        libraries
        * sql/table.lisp: Add logic for dealing with Oracle 10g vs. previous
        Oracle versions with the PURGE option required for drop table. This needs
        to be converted to a generic function and moved to db-oracle/oracle-sql.lisp
