  atari.c

  Atari-specific routines for use with Info-ZIP's UnZip 5.1 and later.

  Contains:  readdir()
             do_wild()           <-- generic enough to put in fileio.c?
             mapattr()
             mapname()
             checkdir()
             mkdir()
             close_outfile()
             stamp_file()        [optional feature]
             version()

  Due to the amazing MiNT library being very, very close to BSD unix's
  library, I'm using the unix.c as a base for this.  Note:  If you're not
  going to compile this with the MiNT libraries (for GNU C, Turbo C, Pure C,
  Lattice C, or Heat & Serve C), you're going to be in for some nasty work.
  Most of the modifications in this file were made by Chris Herborth
  (cherborth@semprini.waterloo-rdp.on.ca) and /should/ be marked with [cjh].
