/*
* UAE - The Un*x Amiga Emulator
*
* Try to include the right system headers and get other system-specific
* 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.
