These are very nice contributions, Freddy. I myself haven't been able to
use them yet, but having a framework for comparing the results of
different libraries is very helpful.
I noticed many differences between FreeTDS and Microsoft while replacing
Microsoft's db-lib during a Win64 port. You showed the unit tests match
Sybase pretty well, but many don't even work with Microsoft. I would like
to reduce and isolate those differences, but that's a work in progress. I
don't think we need to resolve them before the next release. For me it's
a 1.0 goal now.

Yes. I'm satisfied for now, although I do think "tsql -L" needs reworking
to be easier to use.

Important, but I'm not going to have time to work on it for the forseeable
future. I'm thinking of nominating it for a SoC project next year.

Still no progress. It's *very* important -- any result-set processing
error is important -- but it's also hard to isolate. We don't have a test
case, just a problem description.

For me, the bcp file-encoding and the db-lib result-set processing issue
are both important. But I don't have much time these days to work on
FreeTDS. If we can't make any real progress on them, perhaps it's better
to release what we have.
