  The thing about returning a value from a void function should 
probably still be allowed under -traditional, since it's just the flip
side of the coin compared to not returning a value from a non-void
function.  K&R C permitted this practice, and the return value of the
function would generally correspond to whatever was calculated by the
last expression evaluated before the function returned.  So before 
completely killing the option it might be relevant to consider what
would happen in an old K&R C program that had something like :

void foo (void)
{
   ...
  return value;
}

int bar (void)
{
   ...
  foo ();
  return;
}
