	* pid_output.c: (pid_output_lock) Eliminate static function, and just
	  use the #ifdef to decide which version of the function to include.
	  This eliminates a compilation problem with gcc4.  And fix the
	  non-fcntl version so that it actually compiles.  Exit with
	  status 1 instead of -1 on error.
