I see some of these as well - no appearant harm AFAICT.

These _may_ be compatible with Firebird now, but the developer has stated
that no effort will be made to keep IBX compatible with Firebird. If you
intend to use Fb (or IB and Fb), you should consider alternative
middleware. I don't know FIBplus, but IBO is ceratinly a good
choice. There's also a 3rd party dbexpress driver (beta?).
