Cross-compiling with Cygwin:
- please notice that you need at least SDL developer files installed with your AmigaOS 4 SDK
- type ./configure --host=ppc-amigaos (you may need to use --with-sdl-prefix option if SDL configuration fails)
- edit config.mak file when needed (optimization settings etc)
- type 'make' and cross your fingers

Compiling with AmigaOS 4 native SDK:
