Another attempted fix for MySQL's declaration of the DelDep variables
that cursors have to be fetched into.  The corrections have been checked
against the PostgreSQL template code for variable declarations.  Once I
get it working in MySQL, I'll consider removing the PostgreSQL template
entirely and copy it from MySQL if it's needed for Sybase ASE and Microsoft
SQL Server.  I don't remember if it is or it isn't at the moment, and I'm
kind of busy dealing with MySQL right now.
