[tor-dev] Building TOR using Visual Studio

[Владимир Мартьянов]

As far as I know only Visual Studio 2013 has C99 support. Upgrade to VS2013
costs about 300$ for commercial versions, a lot of code was written in
earlier versions...
By the way, I fixed only about 10 lines of code and finally I managed to
build the TOR using VS2008, so i think it's not so hard to make the code
suitable for VS2008. How can I show you my changes? Make a diff in git and
attach to the message?
