DR 2289 clarified that since structured bindings have no C compatibility

The duplicate_decls hunk is the gist of the patch, but that alone would
not be enough to detect the 'A' case: cp_parser_decomposition_declaration
uses
13968 tree decl2 = start_decl (declarator, &decl_specs, SD_INITIALIZED,
13969 NULL_TREE, NULL_TREE, &elt_pushed_scope);
to create the 'A' VAR_DECL but in this start_decl's grokdeclarator we
don't do fit_decomposition_lang_decl because the declarator kind is not
cdk_decomp
Why isn't it? I see
cp_declarator *declarator = make_declarator (cdk_decomp);
a few lines up.
