Regardless of whether we consider gcc's behaviour to be correct or not, I do 
agree we need a fix for this in 2.5 final. That should also be backported to 
release24-maint for the 2.4.4 release, and maybe release23-maint, as Barry 
recently started talking about cutting a 2.3.6. 

Can I nominate Tim, with his terrifying knowledge of C compiler esoterica, as 
the person to pick the best fix? 

Thanks,
Anthony
