Now, the question is "is what gcc4 is doing right?".  Since we started
   with a pointer to Elf_Addr, is the optimiser legal in saying that that
   pointer is always aligned so it an optimise the store in to an aligned
   store?  Or is it a bug with gcc4 and memcpy and assuming alignment?


i'm not a language lawyer (i don't even play on on tv) but from
history, the GCC folks definately would consider this a bug in
our code.  if this works for gcc3 and gcc4 please commit it.
