Using DBLIB With Azure

So I am testing TinyTDS with Azure and I am close. I have 0.83.dev installed with OpenSSL and can connect with tsql. 

$ tsql -S azure -U tinytds@abc -P password -D tinytdstest

But I am having an issue with figuring out a way to use a database setting. I know that Azure does not have a notion of "USE ..." or has a way to specify a default database with the user account, so I was let with reverse engineering how tsql accomplishes a connection using the -D option and I am left stumped as to how I can get TDSCONNECTION's database string in there. FYI, TinyTDS only uses sybdb.h and sqlfront.h, so some things that tsql is doing is not a public API. Perhaps there is something that can be done for this? 

I had hoped that putting a database in my freetds.conf would help. For instance.

[azure]
  host = abc.database.windows.net
  port = 1433
  tds version = 8.0
  database = tinytdstest

Since I assumed that this would populate the struct for me. It may just be doing that, but because of login.c (around line 430) never has db_selected to false for high TDS versions? Maybe this is not the right spot too since it ultimately does a "USE " too. I guess the question is, how does tsql work and how can I help make DBLIB work too?
