[freetds] SQLBindParameter incorrectly binds as varchar

Is SQLBindParameter being misused here by openldap?

oc_id is an unsigned long and the call is made like:

SQLBindParameter( sth, (SQLUSMALLINT)(1),		
		0, 0, (SQLPOINTER)(&oc_id), 0,(SQLINTEGER*)NULL )

But rather than being bound as an integer, it's bound as a varchar and 
chokes when the query is executed.

I'm using freetds 0.62.4 (to sybase 12.0) and openldap-2.2.15. Also 
running redhat packages: unixODBC-2.2.8-,
