This subthread is C-specific.  I am redirecting followups to comp.lang.c.

It *was* considered, but rejected.  I suspect the response was "Insufficient
utility; Does not address a major deficiency; No established current practice"
or something like that.

No problem.  Campaign to have it added to gcc; hint to your other vendors that
you like the feature.  If it's current practice when the next time around, it
has a much better chance of making it into C-2000.

The feature doesn't break any existing code.  At worst, it requires a warning
diagnostic when the compiler is run in strictly pedantic ANSI mode.  The fact
that ANSI doesn't support it is not an excuse for not providing it.
