With boost 1.83.0 unit tests still build fine, but from 1.84.0 and later building fails. For example:

azmq> /build/source/test/cpp20/socket/main.cpp:32:18: error: 'BOOST_CURRENT_FUNCTION' was not declared in this scope; did you mean 'BOOST_CURRENT_LOCATION'?
azmq>    32 |     sb.bind(subj(BOOST_CURRENT_FUNCTION));
azmq>       |                  ^~~~~~~~~~~~~~~~~~~~~~
azmq>       |                  BOOST_CURRENT_LOCATION

GCC's suggestion is in this case wrong and instead one probably needs to #include <boost/current_function.hpp>. The file and macro is available since boost 1.65.0. Maybe it was transitively included in previous boost releases, but is not anymore so.
