I can add a bit of additional info:

- At the time I understood - also thanks to private exchanges with Mark, 
if I remember correctly - that the real, complete solution required 
quite a bit of work. At the same time, I managed to prepare the 
*minimal* implementation of tr1/aligned_storage that I was looking for 
(basically by following the hint in tr1 itself about unions and avoiding 
typedefs) and personally stopped really pushing small scale fixes for 
the short term.

- Then, at GCC Summit, when I reminded the open issue, Nathan vaguely 
told me that maybe he could work on the long standing issue in the near 
future: maybe he wants to add something... ;)

Ciao,
Paolo.
