C5240: 'maybe_unused': attribute is ignored in this syntactic position #120
Description
When including the generated header files we see many 'maybe_unused' compiler warnings in Windows Visual Studio 2022 (17.8.2), e.g.:
boost/phoenix/core/detail/cpp03/preprocessed/argument_predefined_10.hpp(21): warning C5240: 'maybe_unused': attribute is ignored in this syntactic position
Could be fixed by pull request #119
