  LIST OF DEFINES
  ===============

  BYTEORDER	[byteorder]     Should either be set to BIG_ENDIAN or LITTLE_ENDIAN depending on the processor.
  INLINE    [prefix]        Defines the prefix for inline functions, normally _inline.
                             Skip this define if your compiler doesn't support inline functions.
  DRAG_DROP                 Set if Drag-n-Drop operations are supported. If defined, the hint for drag and drop
                             is displayed in the help menu.
  PRIO                      Set if priority can be set with the -PRIO switch.
  MSWIN                     Set this for windows systems. Includes "windows.h" etc.
  WILDCARDS                 Set this if the program has to expand wildcards itself on your system.
  NO_ZERO_CALLOC            Set this to work around a bug when allocation 0 bytes memory with some compilers.
	DIRECTORY_SEPARATOR				Should either be '\\' or '/'.
	WAIT_KEY									Set this on systems where we as default want to wait for a keypress before quiting.
