We explicitly document (under Non-bugs in trouble.texi) that we don't do this, and -funsigned-bitfields is also incompatible with C++14 and later. So stopping adding -funsigned-bitfields like that, and telling users of this port to pass that option explicitly if they want its effects in future, would seem the obvious thing to do. -- Joseph S.
