char * OSDetection ()
{
  ...
  sprintf (szOperatingSystem, "%sversion %d.%d %s (Build %d)",
           szOperatingSystem,
           osvi.dwMajorVersion,
           osvi.dwMinorVersion,
           osvi.szCSDVersion,
           osvi.dwBuildNumber & 0xFFFF);
  ...
  sprintf (szOperatingSystem, "%s%s(Build %d)",
           szOperatingSystem, osvi.szCSDVersion,
           osvi.dwBuildNumber & 0xFFFF);
  ...
}
