 100   LIST OF DEFINES
 101   ===============
 102
 103   BYTEORDER     [byteorder]     Should either be set to BIG_ENDIAN or LITTLE_ENDIAN
 104                                                          depending on the processor.
 105
 106   DRAG_DROP                 Set if Drag-n-Drop operations are supported. If
 107                                                          defined, the hint for drag and drop is displayed

 109
 110   PRIO                      Set if priority can be set with the -PRIO switch
 111                                                          (UNIX_SYSTEM enables this automatically).
 112
 113   MSWIN                     Set this for MSWin systems. Includes "windows.h" etc.
 114
 115   WILDCARDS                 Set this if the program has to expand wildcards
 116                                                          itself on your system.
 117
 118   DIRECTORY_SEPARATOR           Should either be '\\' or '/'.
 119                                                          (UNIX_SYSTEM automatically gives you '/').
 120
 121   WAIT_KEY                                      Set this on systems where we as default want to
 122                                                          wait for a keypress before quiting.
 123
 124   UNIX_SYSTEM                           Set this for UNIX-systems that are posix and
 125                                                          (at least to some extent) bsd compliant to enable
 126                                                          stuff like config-file support, priority settings etc.
 127
 128   PAUSE_25_LINES                        Wait for keypress after 25 lines of output when
 129                                                          listing important information.
