I don't know why compilation failed... I'll try.
Also I noted there is no documentation for Sybase servers.

Thanks, I was wondering about the failues as well, since it was just simple documentation. Apologies for the lack of Sybase, but I have never worked with Sybase, just MS SQL Server. I answer a lot of questions on this topic on Stack Overflow and noticed there was a ton of confusion around TDS versions and SQL Server (most of the questions involved it in one form or another) so I decided a PR might help. If you take a look at a few of my answers, you can see the pattern: http://stackoverflow.com/users/1394697/flipperpa?tab=answers

Thanks for all of your amazing work on FreeTDS.

I think would be enough to change "SQL Server" to "Microsoft SQL Server" and put a line like

"If you have a Sybase server use version 5.0 otherwide if you have Microsoft SQL Server you can follow following section."

well.. or something better than this.

I've updated the text to include the sentence about Sybase. I hope this helps!

Merged. I removed the "Microsoft Microsoft SQL Server" and the "Microsoft" where "SQL Server" was referring to any SQL Server (Sybase or Microsoft).
I also split some too long line so on next diff they will be smaller.
