How can RSTan be installed so that it uses mingw_64 tool chain instead of the mingw_32?
RStan's installation does not depend on the bitness of mingw. At runtime, it uses whatever compiler is available. If you have a 64 bit machine, it should be using the 64 bit compiler, unless you have it set to cross compile.
