But there is nothing in the specs that states that always all
conditions need to be evaluated or at least checked if they can be
evaluated reasonably.  To me, the new behaviour makes no sense -
neither logically not performance-wise.

I am aware that common sense and gcc behaviour is not always in the
same pot, but I consider this to be a change to the worse.

Can you point to some commit / bugzilla entry / posting that contains
an explanation or rationale for this change?

Best regards,

Wolfgang Denk
