Does this "match" with that it works for non-template classes? I.e.

struct foo2 {
        float bar __attribute__((aligned(__alignof__(double))));
};

just works.  Remember that "double" is not a dependent type - I would
certainly understand that using a dependent type would not work (or
would be harder to do).  But not allowing non-dependent types in template
classes doesn't look difficult (from a users point of view), are they?

Thanks for trying to explain,

Richard.
