Per: https://svn.boost.org/trac/boost/ticket/2899 we have a problem that the default set of libraries build on Windows does not match autolink defaults, which causes confusion. In that issue, John say that the only sensible solution for Windows is to build all possible variants by default (IIRC, a total of 6). I would like other Windows developers to comment if that is sensible solution. In particular, is it best to build all possible variants that user might need, or build just the variants that autolink needs by default, so that user can build other later. Note that I can add arbitrary explanation messages into the build process -- both to warn the user that a scary pile of things will be built, and to warn the user that only couple of variants will be built. - Volodya
