/*
KolibriOS port for gcc 5.4
Started by Siemargl @Nov 2016
Borrowed code parts from other unzip ports
howto make:
go in unzip60 directory (below this file) and
>make -f kolibri\makefile.gcc
Contains:
version()
mapattr()
mapname()
checkdir()
close_outfile()
get_extattribs()
do_wild()
set_direc_attribs()
defer_dir_attribs()
todo
datetime restore for dirs. buf in unzip - crash when SET_DIR_ATTRIB
fixed partial
-d dir error (only in unicode). Use -ddir or -d dir/
russian filenames in arhives. Now works cp866 version, unicode need to fix @kos32.c:470 (GETPATH)
