In alpha/alpha.c we have:

alpha_build_builtin_va_list (void)
{
  tree base, ofs, space, record, type_decl;

  if (TARGET_ABI_OPEN_VMS || TARGET_ABI_UNICOSMK)
    return ptr_type_node;

  record = (*lang_hooks.types.make_type) (RECORD_TYPE);
  type_decl = build_decl (TYPE_DECL, get_identifier ("__va_list_tag"), record);
  TREE_CHAIN (record) = type_decl;
  TYPE_NAME (record) = type_decl;

  /* C++? SET_IS_AGGR_TYPE (record, 1); */

  ...

So, actually there is no way we can SET_CLASS_TYPE_P (t, 1) on the created
RECORD_TYPE. IOW, we should somehow be able to reach cp/lex.c/make_class_type
() function from target .c file.
