Fixes Windows Visual Studio 2022 (17.8.2) warning C5240: 'maybe_unused' attribute is ignored in this syntactic position
When including the generated header files we see many 'maybe_unused' compiler warnings, e.g.:
boost/phoenix/core/detail/cpp03/preprocessed/argument_predefined_10.hpp(21): warning C5240: 'maybe_unused': attribute is ignored in this syntactic positionBe warned: I fixed these manually - maybe there is a generating mechanism involving 'BOOST_PHOENIX_ARGUMENT_N_INSTANCE' that I dont know of. But this works as intended in our code base.
