  small changes for OS/400
  
  OS/400 version V5R3 is not supported by IBM anymore.
  In addition, the iSeries system I have here for development has been changed
  and the new system is not able to compile for an OS version lower than V6R1.
  
  Thus I made some updates to the libxml2 os400 scripts accordingly:
  
  - Oldest supported OS version is now V6R1.
  - Adjust ILE/RPG wrappers comments.
  - Update copyright year range.
  - Do not log compiler informational messages.
