// There were two related problems here, depending on the vintage.  At
2
// one time:
3
//
4
//    typedef struct A { ... } A __attribute__ ((aligned (16)));
5
//
6
// would cause original_types to go into an infinite loop.  At other
7
// times, the attributes applied to an explicit typedef would be lost
8
// (check_b3 would have a negative size).

10
// First check that the declaration is accepted and has an effect.
