The mentioned package fails to build with gcc12 as:

One of the reason is the extensive usage of 'using namespace std', which maps
'enum class std::byte' into the global namespace, which then conflicts with

/usr/i686-w64-mingw32/sys-root/mingw/include/rpcndr.h:397:170: error: reference
to 'byte' is ambiguous
