I reopen the bug so we don't forget about this for 4.0.2.

Stephen, to clarify: we know that this is indeed a bug, and this is why it 
*was* fixed for 4.1. The fact is that the 4.0 serie is already out so we 
usually just consider regression fixes for it (that is, patches which fix 
problems appeared in 4.0 which were not present before). Since the code you 
provided never worked on any version of GCC, we assume it could wait another 
iteration up to 4.1. Anyway, Mark already approved it for 4.0.2 as an exception 
to the rule, so the fix will be present in that version.
