Show me.  I maintain that the standard does not proscribe this.

The entire description is 

  3.4.1 implementation-defined behavior
  unspecified behavior where each implementation documents how
  the choice is made.

and 

  J.3 Implementation-defined behavior
  A conforming implementation is required to document its choice
  of behavior in each of the areas listed in this subclause.

GCC's choice of behaviour is to not cater to smart-asses who are
trying weasel-word their way around 6.5.6/8.
