Following up on my pdo_dblib thread, I'd like to be able to detect which
version of FreeTDS is installed. So I can know when the dbnextrow()
workaround should be used instead of dbcanquery(). As far as I can tell,
the version only gets exposed through dbversion(), which is a string I'd
have to parse.

Thanks,
Adam
