In tds_connect, we can set TDSSOCKET::tds_ctx->err_handler to a special
no-op handler.  Restore the client's handler  after success or just before
attempting with 4.2.

Well, not a problem, really. It might be interesting to see the
differences.  We don't make any claim or attempt at binary compatibility. 
If you want to use FreeTDS, you use FreeTDS's sybdb.h.  Anything else is a
crapshoot.
