Supposing that's the direction followed, it would be appropriate to have information on the web site about best practices for suppressing all or most warnings from Boost headers in user environments. Thus, you could describe the PCH approach on such a page for the benefit of Windows developers and another could describe the approach needed for other compilers/platforms. That information should be prominently featured for easy discovery.

There may well be no other way to reach agreement.
