You may well find that that table is empty, in which case you can just drop it before installing Moodle.
Basically, this is a table used by the ADODB database connection library we are using, and the name is stupidly hard-coded into the library, so we can't change it to use the database prefix. However, we have to create it. And currenly, in the Moodle install system, there is no way of saying "create this table but only if it does not exist yet".
Well, it's just stats. I am sure it is pretty safe to drop it if it's there 
Its lack of prefix makes it a pain in databases using multiple prefixes.
