NandTest. Wrong conversions

[heretic13]

case 'l': length = strtol(optarg, NULL, 0);

Function description:
long int strtol (const char* str, char** endptr, int base);

Signed conversion function for unsigned numbers. Really?

Try the key "-l 0x 0xFFE00000". This does not work!!!

[heretic13]

case 'o': offset = atol(optarg);

Function description:
long int atol ( const char * str );

Signed conversion function for unsigned numbers. Really?
