I'm very reluctant to mess with the manifest stuff.  I was told
personally by Martyn Lovell of Microsoft that it was necessary and he
helped me to get it right in our Boost.Python build.  I don't really
understand the manifest stuff at a deep level, so the fact that you
found -D_CRT_NOFORCE_MANIFEST suppresses the problem you're seeing
doesn't lead me to the conclusion that it's really a "fix."
