Using the attached batch file (below) to make Boost 1.55 beta 1 - I did NOT have success building Boost 1.55b1 with the release version of VS2013. I was however on a different PC able to build Boost with successfully with this batch file using VS2012. Others have reported successful builds using VS2013 – am I missing something new?
