Contents of the "atari" sub-archive for UnZip 5.3 and later:
Contents this file
README.old old notes on compiling UnZip, from author of Atari port
Makefile.old makefile for GNU C compiler and MiNT libraries
Makefile newer, Unix-based makefile (lots of unnecessary baggage :-( )
make_unz.mup script file for invoking makefile(s)?
atari.c Atari-specific routines
The maintainers of the Atari port have fallen behind in their duties; the
code *probably* compiles, but it has not been tested recently. Feel free
to send zip-bugs e-mail about this sorry state of affairs.
