  * UAE - The Un*x Amiga Emulator

  * stuff right & other collected kludges.
  *
  * If you think about modifying this, think twice. Some systems rely on
  * the exact order of the #include statements. That's also the reason
  * why everything gets included unconditionally regardless of whether
  * it's actually needed by the .c file.
