Or if not recompile, indicate the TDS protocol in freetds.conf or
TDSVER.

Your local SQL Server is by Microsoft and accepts TDS 5.0 connections?

1433 is the default port.  Your named instance may be on another port.

That command bypasses freetds.conf, so your TDS protocol version (7.0 or
8.0) has to be either compiled in or set in TDSVER.

An instance name is just dataserver entry in freetds.conf: a tcp/ip
address (or DNS name), a port, and a protocol version.  

In the next release (or the current snapshot), you'll be able to name
your instance in freetds.conf.  The current UG describes how.  But the
server doesn't use the instance name at connection time!  What's really
happening is that the server runs a kind of mini-DNS: we issue a query
to iirc 1434 asking for the port assigned to a given name, then we
connect to the port.  If we know the port in advance, we can skip the
interrogation.

No.  If the instance is named in freetds.conf and you don't bypass it
with tsql, it will of course use the information.  But there's no new
tsql parameter to override it; you just indicate the addrees & port
instead.
