need add code for cpu cores detection

[ai386]

SYSTEM_INFO sysinfo; GetSystemInfo(&sysinfo); int cores = sysinfo.dwNumberOfProcessors;

and

        case 'l':
            this->SetLimit(atoi(optarg)*cores);
            break;

and

if (l < 1 || l > (100*cores))
{
    fprintf(stderr,"Error: Limit must be in the range 1-100.\n");
    this->m_error += 1;
}
