Ugh. The mere existence of a function called "tds_fix_connect" is
symptomatic of a problem, if you ask me. Every time I look at this, I
think: We need to separate reading freetds.conf from connecting to the
server. Before we start connecting to the server, we should *know* the
options we're going to use. All the juggling of default, environment, and
freetds.conf should be done in advance.

Eventually, as you know, I'd like to replace our config-file parser with my
nvp library. In the meantime, you probably have the best knowledge of how
to fix the "2c" problem.

That looks promising.
