// There were two related problems here, depending on the vintage. At

// typedef struct A { ... } A __attribute__ ((aligned (16)));
//
// would cause original_types to go into an infinite loop. At other
// times, the attributes applied to an explicit typedef would be lost
// (check_b2 would have a negative size).
// First check that the declaration is accepted and has an effect.
