odbc install error on Windows

I'm trying to install 8.3.1 (binaries) on Win2003 using windows
installer (msi).
I'm runnning silent install with:

ADDLOCAL=server,psql,pgadmin,psqlodbc,nls

and I'm getting error message saying, that "psqlodbc is not included in
the package".

When I exclude odbc:

ADDLOCAL=server,psql,pgadmin,nls

install works fine.

Is it true that odbc was excluded from 8.3.1 Windows distribution
package?
Should I change my scripts to run separate odbc install?

I didn't have this problem with 8.2: odbc was in cluded along with
everything else.

Thanks in advance,
Igor
