Hi, 1) the macro BOOST_HAS_CONCEPTS from (https://www.boost.org/doc/libs/1_81_0/libs/config/doc/html/boost_config/boos...) not work: https://godbolt.org/z/3G8vTrjcf

This macro indicates support for C++0x concepts that were not accepted, not the C++20 concepts. I don't thing we have a macro for C++20 concepts.
