Ok, I've finally bootstrapped myself up with a working OpenLDAP 
installation with unixODBC 2.2.0 and all the rest.  Created a set of 
sybase sql files while I was at it.  Have to contribute them...

It's an old bug. ODBC allows one to bind (either SQLBindParameter or 
SQLBindCol) between when a query is prepared and when it is executed.

Since we don't actually know anything about the query until execution time 
we can't assign the proper values into the right structures (they don't 
exist).  What use to happen is a temporary linked list _sql_bind_info was 
kept and then applied during SQLExecute(). Somewhere along the line this 
got removed and now it's bitten us.

I'll see what I can do to put it back in place.
