  Modified:    sys/sys   cdefs.h
  Log:
  Add __unused to the list of __dead, __dead2, __pure, __pure2 etc.
  
  gcc-2.7 has __attribute__((unused)) as a postfix operator on function
  arguments to prevent -Wunused from complaining about them.  gcc < 2.7
  doesn't have anything like this (and doesn't care about it either).
  
  eg:
  int foo(bar, baz)
    int bar __unused;	/* needed because of function pointer typing */
    char *baz __unused;
  {
    return (1);
  }
