This breaks a -O3 bootstrap (-Werror turns the warning into an error). The code
looks like:
  VEC(tree,gc) *origtypes;
  ...
  if(...)
exprlist = NULL;
  else
exprlist = c_parser_expr_list (parser, true, false, origtypes);
  ...
  expr.value = build_function_call_vec (op_loc, expr.value, exprlist,
origtypes);

So g++ is right to warn (even if origtypes is probably unused in that case).
