Example error messages by gstat:
Wrong ODS version, expected 8, encountered 32779?
InterBase 4.x tries to open Firebird 2.x database

Wrong ODS version, expected 8, encountered 13?
InterBase 4.x tries to open IntrBase 2009 database

Wrong ODS version, expected 15, encountered 32779
InterBase XE/XE3 tries to open Firebird 2.x database

Wrong ODS version, expected 11, encountered 15
Firebird 2.x tries to open InterBase XE/XE3 database


Example error messages from server (client):
unsupported on-disk stucture for file ...; found 32779, support 10
Firebird 1.0/1.5 or InterBase 6.0 tries to open Firebird 2.x database.

Firebird 2.x, to make ODS distinguesable from InterBase 7.x and higher
adds higher bit (x8000) to the ODS.
In hex ODS 32779 will be 800B, that means Firebird's ODS 11.
