We don't remove unused static function variables.  Take the following code:
static int iii;
void f(int i)
{
  i = 0;
  if(i)
  {
   static int ii;
   const char *c = __FUNCTION__;
   iii = 0;
  }
}

There should be no ii or reference to __FUNCTION__.  We do remove the refence to iii though.

Fixed by:
	* cfgexpand.c (expand_one_stack_var): Do not expand variables when we
	do unit-at-a-time.


Thanks Honza.
