The patch as it is focused on bringing in the core support for c++11
attributes.  Supporting some attributes in particular is left as a
follow-up to come up later.  An exception to this is that the patch also
supports alignas expressions, but that is just because it was needed to
complete the support of the attributes syntax.

I haven't looked at the details yet, but I think you are correct.

I think it works with the version of the patch that I just committed.
Or maybe I don't understand what you mean by "doesn't work".

Thanks for caring.
