This is a port of GNU Gzip 1.3.5 to MSDOS/DJGPP.
DJGPP specific changes.
=======================
This port is based on the previous ports gzip13X[bds].zip which are based on
Eli Zaretskii's port of GNU Gzip 1.2.4a (aka gzp124a[bds].zip). This means,
that all the djgpp specific funtionality introduced with those ports will
also be available in this new port.
This is a recompilation of all new features introduced with gzp124a
and also available in this port:
- Gzip now fully supports long file names on those platforms where DJGPP
can access them. This means, for example, that compressing `foo.tar' on
Windows 9X will produce `foo.tar.gz', not `foo.tgz'.
For backward compatibility, Gzip knows about butchered DOS-style
extensions of compressed files even when long file names are supported.
For example, if you have `foo.tgz' and you type "gunzip foo.tar", Gzip
will find the file even on Windows 9X. Short variants of compressed
extensions are checked *after* the long ones, so Gzip will try to find
`foo.tar.gz' before `foo.tgz'.
Long file name support is checked for each file submitted to Gzip, so
it will treat each one of them in accordance with the properties of the
file system where that file resides. In other words, you can compress
files that reside on DOS and Windows file systems within a single Gzip
command.
- Gzip will no longer appear to hang when its input comes from the console
device. Previous ports would hang when the user typed "gzip -f [Enter]".
This port allows you to either interrupt the program with Ctrl-C (if you
typed that command by mistake), or type in the input and end it with a ^Z
(if you really mean to compress the text you type from the keyboard).
This is done by avoiding to switch the console device to binary mode,
so any console reads are now done in text mode.
- The default compressed file extension is now `.gz', not `z'. This is so
that compressed file names on Windows 9X would have the usual `.gz'
extension, but it also means that `foo.cc' will now be compressed into
`foo.cgz' when long file names are not supported. Use the -N option to
`gunzip' to restore the original name, if the original file name had
more than one character in the extension.
- When restoring original file names, `gunzip' now converts all characters
that are not allowed in DOS/Windows file names to similar but valid
characters, and changes the file name if it is reserved by a DOS device
driver (like `aux.text' or `prn.tar') by prepending an underscore to it.
- In previous ports, uncompressing files with certain names on Windows 9X
when numeric tails are disabled would trigger false warnings about file
name truncation. This is now fixed.
- Truncation of long file names on plain DOS is somewhat smarter now:
`gunzip' treats several additional characters (like `-' and `_') as
part delimiters.
- Shell scripts `zmore', `zdiff', `zgrep' and others now work on DOS and
Windows, and are distributed with the binary distribution, as are all
the man pages supplied with the official GNU sources.
- The binaries gunzip.exe and zcat.exe will be installed as symlinks of
gzip.exe.
All the changes done to the original distribution are documented in the
diffs file and located together with all the files needed to configure
the package (config.bat, config.sed, config.site, etc.) in the /djgpp subdir.
There exist a mekefile called makefile.dj located in the /msdos subdir.
This is part of the original FSF gzip-1.2.4 source distribution. I have never
inspected nor used this file, so do not use it or do not ask question if you
decide to use it. This port as well as all the other gzip13X[bsd].zip ports
use the usual configuration files located in the /djgpp directory to create
the configure script, Makefile and config.h.
If you want to recompile the package, run the command:
make
Install the products running the command:
make install
There is no testsuite in this package so test the binary by using it.
As usual I have configured and produced the binaries using stock djdev203.
If you are a WinXP user you will have to reconfigure and recompile from scratch
running the commands:
rm djgpp\config.cache
make distclean
djgpp\config
make
make install
These command sequence will produce and install the binaries, info docs and
unformated man pages in the djgpp installation tree defined by /den/env/DJDIR
The port consists of the usual three packages that can be downloaded from

Send gzip specific bug reports to <bug-gzip AT gnu DOT org>.
Send suggestions and bug reports concerning the DJGPP port
to comp.os.msdos.djgpp or <djgpp AT delorie DOT com>.
If you are not sure if the failure is really a gzip failure
or a djgpp specific failure, report it here and *not* to
<bug-gzip AT gnu DOT org>.
Enjoy.
