/* Modified 29/05/01 : Moved #include <sys/types.h> above #include
      for Amiga port : <sys/stat.h> so that the types used in sys/types.h are
                       typedef'd beforehand

                       Added include "confdefs.h" since we are not using the
                       CONFIGURE script

                       Removed default SHAREDIR, since we can't really assume
                       a default directory on the Amiga
