Well, I think of the unittests as testing baseline functionality.  They
don't ask FreeTDS to do anything it can't, and they should always succeed
unless we break something.  

On that basis, I think t0022.c should test for the TDS version and execute
only if it's < 7.0.  Else it should write a warning to stderr indicating
that output parameters are unsupported for such-and-such a version at the
present time, but return success (since the unsupportedness is anticipated).


The nice-guy approach would be to check dbtds() in dbretname() and issue a
client-side error message if the TDS version is out of range.  Wouldn't you
say?
