I believe you'll have hard time proving that my interpretation is
INcorrect according to the *current* standard (C++98, C++03), and
under obvious reading.  

Since, I'm not suggesting a change to the current standsard to match
my interpretation -- since it already does -- and the only change I'll
be proposing is to make C++0x match C99 rules, if you're going to oppose my
proposed changes, then you are going to oppose a change that allows
TBAA in the form currently implemented in GCC.  
I'm not sure, that really is what you wanted.
