tds version = 7.1 causes dbbind to find for me

OpenVMS IA64 V8.4.  FREETDS-1_00_15.  SQL Server 2014 - 12.0.4213.0.

When tds version = 7.0, everything is good.  But when I set to 7.1 or later, dbbind fails with (TDS Msg 20033, Level 7, "User attempted a dbbind with mismatched column and variable types").

My sequence code is approximately this:

    char tt[128] = {0};
    strcpy (command_string, "SELECT SERVERPROPERTY ('productversion')");
    EXECUTE_CHECK_ERC (dbcmd (dbproc, command_string), "dbcmd", (char*)command_string);
    EXECUTE_CHECK_ERC (dbsqlsend (dbproc), "dbsqlsend", (char*)command_string);
    EXECUTE_CHECK_ERC (dbsqlok (dbproc), "dbsqlok", (char*)command_string);

    while ((erc = dbresults (dbproc)) != NO_MORE_RESULTS)
    {
        CHECK_ERC ("dbresults", command_string);
        EXECUTE_CHECK_ERC (dbbind (dbproc, 1, NTBSTRINGBIND, sizeof(tt), (BYTE *) &tt), "dbbind", command_string);
    }

Is tds version 7.1 something that should be expected to work?
