- use of AString instead of std::string (no more need of #include <string>")
- makefile.linux_gcc_2.95_no_need_for_libstdc added to build 7za for the
p7zip*_bin.tar.bz2 package.
7za provided by p7zip*_bin.tar.bz2 is build on Debian 3.0 with gcc 2.95.4
and should now find the locale on all kinds of Linux (Debian, Fedora, Mandrake, ...).

(on some MacOSX, CC is a link to gcc instead of g++)
- new flag "-utf16" to enable "utf16" conversion [Bug #1075229].
- new logic to automatically enable or disable "utf16" conversion :
no locale, locale=="C" or locale=="POSIX" implies utf16=off
else utf16=on
uses "-utf16" or "-no-utf16" to change this behaviour.
[Bug #1075229]
- 7z (compiled with -O2) works now on Sparc Solaris.
Version 4.12
============

with filename "file", "FILE", "File" ...
- p7zip now displays the locale (ex : en_US.UTF-8) in the banner.
- new flag "-no-utf16" to avoid lossly conversion in filenames.
CAUTION : use this flag when you do not plan to export your archive.

=> p7zip now work on big endian CPU.
- 7z for Unix is not maintain anymore (because as the source of unrar plugin for 7z
is not available, 7z is unless on Unix).
Version 0.91
============
- add support for FreeBSD 5.2.1
In Windows/Time.h add "#include <time.h>"
and prototype change for FileTimeToUnixTime()
- bug 990684 Corrected : support of filesystem
that support case sensitive filenames.
Example, since version 0.91 :
"7z a glibc -r glibc-2.3.2"
does not terminate with error :
Duplicate filename:
glibc-2.3.2\sysdeps\m88k\m88100\add_n.S

and include_windows/initguid.h
- some changes in 7zip/Crypto/aesopt.h because of endian.h
Version 0.81
============
- add a copy of the help of 7-zip (see html directory)
- "7z a -r tmp.7z directory" works as expected.
no more need for commands like : 7z a -r tmp.7z "directory/*"
- 7z restores the date of each files (but not directories)
- 7z supports UNICODE filenames (version 0.80 supports only ASCII/Latin1 filenames)
- support of gcc 2.95
