I have blogged about the problem and solution [http://www.npcglib.org/~stathis/blog/2016/02/21/windows-task-building-boost-against-static-icu-with-msvc/ here]. To cut a long story short, sicuXX.lib files should be detected when static linking and also if the runtimes are static, instead of , the feature should be used. I have written a rough patch for my own use, which does that, but it may not be entirely clean for upstream. It is [http://www.npcglib.org/~stathis/downloads/boost_1.60.0.patch here] though in case you decide to fix it properly. It would be nice until (and if at all) this is fixed the documentation or at build time this limitation was made clear. Currently the user is left to believe he has a statically linked Boost against ICU. I will try to improve my patch in the next iteration, but I'm still learning Boost.Build. thanks.
