Dreaded "Server SYBASE not found!" question

I'm not sure if this is a unixODBC question or a freetds question, but
starting here.  I can connect to the server just fine with tsql, but
have problems with isql.  It appears as if neither the
connection->ip_addr nor the are connection->server_name filled in in
tds_connect() in freetds' login.c

There's an outstanding todo in login.c to open the log file prior to
tds_set_server() where "SYBASE" is being set in to
connection->server_name, but it's not at all clear why the server
name/IP aren't being set correctly since the server info is clearly
being found in freetds.conf.  My combined osql/TDSDUMP dump is below.

I only recently added the Servername to my odbc.ini, directing the
freetds.conf lookup.  The result is the same both with and without the
Servername (osql finds the correct info either way, but it doesn't seem
to get passed in to freetds)

Any assistance would be appreciated.
