>Description:

	sscanf(), and maybe scanf ..., fails on 64-bit operation.

	On Solaris, IRIX and Linux systems, the code below outputs:

	% hextodec -r 963870220966261
	0x00036CA286215975

	% hextodec 0x00036CA286215975
	963870220966261

	% hextodec 0x2804C6B886215975
	2883648157250574709


	Under FreeBSD
 	% hextodec -r 963870220966261
	0x2804C6B886215975

	% hextodec 0x00036CA286215975
	2883648157250574709

	% hextodec 0x2804C6B886215975	# this seems correct
	2883648157250574709


>How-To-Repeat:

	main(argc, argv)
	{
	int rev, i = 1;
		if (!strcmp(argv[i], "-r"))	{
			rev = 1;
			i++;
		} else	rev = 0;
	{
        int64_t h;
                rev ? sscanf(argv[i], "%lld", &h) : sscanf(argv[i], "%llx", &h);
                printf(rev ? "0x%016llX\n": "%lld\n", h);
        }
	}
