I just got bit by this. For the record, I don't think it's Boost.Config's business to be defining std::move, std::forward, etc.
It's not like this is a first. // BOOST_NO_STDC_NAMESPACE orkaround --------------------------------------// // Because std::size_t usage is so common, even in boost headers which do not // otherwise use the C library, the <cstddef> workaround is included here so // that ugly workaround code need not appear in many other boost headers. // NOTE WELL: This is a workaround for non-conforming compilers; <cstddef> // must still be #included in the usual places so that <cstddef> inclusion // works as expected with standard conforming compilers.
