// In the following we configure various targets, in particular those
// which can't use our "configure" tool and hence don't use config.h.
//
// Some #defines that occur here frequently:
// SCUMM_LITTLE_ENDIAN
//    - Define this on a little endian target
// SCUMM_BIG_ENDIAN
//    - Define this on a big endian target
// SCUMM_NEED_ALIGNMENT
//    - Define this if your system has problems reading e.g. an int32 from an odd address
// SCUMMVM_USE_LONG_INT
//    - Define this if your port needs to use 'long' for the int32 datatype
//      (i.e. an integer with exactly 32 bits).
// SCUMMVM_DONT_DEFINE_TYPES
//    - Define this if you need to provide your own typedefs, e.g. because your
//      system headers conflict with our typenames, or because you have odd
//      type requirements.
// SMALL_SCREEN_DEVICE
//    - ...
// ...

// We define all types in config.h, so we don't want to typedef those types
// here again!
