The warning noticed by Jon seems a latent issue unrelated to bitfields and due
to the fact to for scoped enums, the underlying type, if not explicitly
specified is if fixed to int type. Thus, in finish_enum_value_list,
fixed_underlying_type_p is true and the code "restricting" ENUM_UNDERLYING_TYPE
for the benefit of diagnostics doesn't run. It seems that it should run anyway,
when the underlying type is fixed but implicitly so.
