Implementation note in that case: bit-precise integer types aren't allowed
as underlying types for enums, so the code in
c-parser.cc:c_parser_enum_specifier checking underlying types:
else if (TREE_CODE (specs->type) != INTEGER_TYPE
&& TREE_CODE (specs->type) != BOOLEAN_TYPE)
{
error_at (enum_loc, "invalid %<enum%> underlying type");
would then need to check that the type isn't a bit-precise type.
