Did anyone get a chance to review the patches that I sent earlier?
Is there a prospect for getting these patches included?

I am using Boost.Build in a large high performance computing effort and would
really benefit from having these changes included--the CMake evangelists that
I work with are becoming quite loud and I'd like to avoid that path if
