Re: [tor-dev] Building TOR using Visual Studio

• Some people want to use paid versions of Visual Studio, and have

paid for a version earlier than VS2013, and don't want to pay for a newer one. I sympathize with this: I've been on paid upgrade treadmills myself, and it's always tempting to save money by skipping steps in the upgrade treadmill. I've even paid for commercial compilers in my misspent youth.

Are there no-cost, non-license-restricted compilers available for Windows that support C99?

I assume MinGW fits: http://www.mingw.org/

MinGW is also what is used to build Tor for the Windows version of the Tor Browser (run on GNU/Linux).
