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?

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].
