The documentation says the lib is not intended for users of boost, but only to aid implementing boost itself. I asked the question some time ago (long before 1.32) and the consensus was that it was in fact public and the documentation was wrong/outdated, but even with this release it didn't change. What's the deal? Did I miss anything?
OK I changed the wording of the help file to read as follows: " Boost library implementations access configuration macros via #include <boost/config.hpp>. Boost library users are never required to #include <boost/config.hpp> directly, unless they are using the Boost informational or helper macros which are designed for use by Boost users as well as for our own internal use. However, note that while all the Boost configuration macros are documented here, the feature test and defect test macros are designed for internal use by Boost libraries. If you write code that depends upon these you should be aware that they are subject to the needs of Boost library developers, and while we will try to avoid gratuitous changes, subtle breaking changes are not entirely unknown. " Is that clear enough? John.
