Log message:
	  Fix failures on MS-Windows when Make's standard handles are invalid.
	  This can happen when Make is invoked from a GUI application.
	
	  * w32/subproc/sub_proc.c (process_init_fd): Don't dereference
	  pproc if it is a NULL pointer.
	  (process_begin, process_cleanup): Don't try to close pipe handles
	  whose value is INVALID_HANDLE_VALUE.
	  (process_easy): Initialize hIn, hOut, and hErr to
	  INVALID_HANDLE_VALUE.  If DuplicateHandle fails with
	  ERROR_INVALID_HANDLE, duplicate a handle for the null device
	  instead of STD_INPUT_HANDLE, STD_OUTPUT_HANDLE or
	  STD_ERROR_HANDLE.  Don't try to close pipe handles whose value is
	  INVALID_HANDLE_VALUE.
	
	  * function.c (windows32_openpipe): Initialize hIn and hErr to
	  INVALID_HANDLE_VALUE.  If DuplicateHandle fails with
	  ERROR_INVALID_HANDLE, duplicate a handle for the null device
	  instead of STD_INPUT_HANDLE or STD_ERROR_HANDLE.  Fix indentation.
	  Don't try to close handles whose value is INVALID_HANDLE_VALUE.
