Has the conclusion w.r.t. to TDmode alignment been reached? Looking
into the thread at [1], I don't think that we have authoritative
answer on this issue. I think that to avoid possible ABI
incompatibilities with future gcc versions, this should be finalized
before 4.3.1 is released.

I agree. If we don't already have a P1 issue, please open one. We can always decide to downgrade it, but we shoudn't forget.

Thanks,
