[Mondrian] Infobright Distinct Count

I ran the test suite in its current suite through InfoBright and attached the log. 

Excuse my mornic understanding, but if I run the test suite as is, doesn't it run with the current IB dialect and prove nothing? :)

Thanks. Looking forward to those results. Attach a patch to the jira case
when you have one.

If I remember rightly, in the previous version there was an outright error,
not just a warning.

In previous versions of Infobright the concern was not correctness. If the
feature was not handled by the Infobright engine it would fall through to
MySQL and performance would be abyssmal.

It looks like every version of Infobright has significant improvements. Keep
a close eye on that log4j.category.mondrian.sql output and let me know if
you see anything else that is odd.
