	if(fprintf(stderr, "...: operation failed\n") == FAIL) {
		if(!(fp = fopen("/dev/tty", "w"))) {
			if(!(fp = fopen("/dev/console", "w"))) {
				chdir("/tmp");
				abort();
			}
		}
		(void)fprintf(fp, "...: operation failed\n");
		fclose(fp);
	}

And to be totally safe, use open()...

Not entirely smiley. There are programs that don't have 0, 1, and 2 open
for lengths of time. Like, a modem callback program...
