* version 1.2.4
By default, do not restore file name and timestamp from those saved
inside the .gz file (behave as 'compress'). Added the --name option
to force name and timestamp restoration.
Accept - as synonym for stdin.
Use manlinks=so or ln to support either hard links or .so in man pages
Accept foo.gz~ in zdiff.
Added support for Windows NT
Handle ENAMETOOLONG for strict Posix systems
Use --recursive instead of --recurse to comply with Webster and
the GNU stdandard.
Allow installation of shell scripts with a g prefix: make G=g install
Install by default zcat as gzcat if gzcat already exists in path.
Let zmore behave as more when invoked without parameters (give help)
Let gzip --list reject files not in gzip format even with --force.
Don't complain about non gzip files for options -rt or -rl.

Force lower case file names only for FAT file systems (not HPFS)
Rewrite one expression in inflate.c to avoid cc bug on Solaris x86.
In the msdos makefiles, get match.asm from the msdos subdirectory.
Catch SIGTERM and SIGHUP only if they are not ignored.
getopt.c: on Amiga, "#if !defined(const)" does not compile.
Use register parameters on Amiga.
Do not force names to lower case on Amiga.
Fix support of Atari TOS (Makefile.st and tailor.h)
In unlzw.c, do not suggest using zcat if zcat already used.
In INSTALL, suggest using bsdinst for HPUX.
Document Turbo C++ 1.0 bug in INSTALL.
Improved the documentation relative to the --no-name option.
Avoid signed/unsigned warnings in several files.
Added pointer to jka-compr19.el in README.
Added pointer to OS/2 executables in README.
Added --block-compress in tar -z example (gzip.1 and gzip.texi).
Don't keep rcsid in executable (avoid compilation warnings).
Check also the correctness of the first byte of an .Z file.
Return non zero status for an invalid option.
Remove "NEWFILES" from os2/gzip.def for Borland C++ on OS/2.
Remove "time stamp restored" message (just obey the -N request).
Thu Jun 24 10:27:57 1993 Jean-loup Gailly (jloup@chorus.fr)
* version 1.2.3
Don't display the output name when decompressing except with --verbose.
Remove usage of alloca in getopt.c and all makefiles.
Use ASCPP instead of CPP to avoid breaking AC_HEADER_CHECK on RiscOS.
Added the zfile shell script in subdirectory sample.
Moved the list of compiler bugs from README to INSTALL.
Added vms/Readme.vms.
Fix DIST_BUFSIZE check in unlzh.c for 16 bit machines.
Fix REGSIGTYP macro in configure.in.
Use 'define' instead of == in vms/gzip.hlp.
Avoid warnings in unlzh.c
Allow separate installation of binaries and man pages.
Simplified handling of file names with spaces in zgrep and znew.
Fix dependencies and remove rule for trees.c in amiga/Makefile.sasc
Add missing quote in gzexe.
Thu Jun 17 13:47:05 1993 Jean-loup Gailly (jloup@chorus.fr)
* version 1.2.2
Fix a compilation error in gzip.c on Sun with cc (worked with gcc).
Wed Jun 16 11:20:27 1993 Jean-loup Gailly (jloup@chorus.fr)
* version 1.2.1

This is the file README for the gzip distribution, version 1.2.2.
This is the file README for the gzip distribution, version 1.2.4.
gzip (GNU zip) is a compression utility designed to be a replacement
for 'compress'. Its main advantages over compress are much better
@ -32,34 +32,12 @@ INSTALL for installation instructions. Some answers to frequently
asked questions are given in the file INSTALL, please read it. (In
particular, please don't ask me once more for an /etc/magic entry.)
WARNINGS about broken optimizers:
- on the NeXT, "cc -finline-functions" is broken. gzip produces
valid .gz files but they are much too large because the string
matching code misses most matches. Use "cc -O" instead.
- on the Mips R4000, gcc -O (version 2.3.1) generates bad code, use cc
or just gcc -g instead.
- gcc 2.3.3 and 2.4.3 on the SGI Indigo IRIX 4.0.5 also produce bad code.
Use instead: make CC='cc -O2' or gcc without -O.
- On Solaris 2.1 for x86, the January 1993 "OEM" compiler release
generates bad code. This is fixed in the June 1993 "FCS" release.
- on Sparc with SunOS 4.1.1 and the SC1.0 compiler, the optimizer
works up to -O3 but -O4 does not work.
- MSC 5.1 with -Ox and -DDYN_ALLOC generates bad code in inflate.c.
The default is static allocation (no DYN_ALLOC) and -Ox works on inflate.c.
But -Ox does not work on util.c, so you must use -Oait -Gs.
- On dnix 5.3 2.2 cc version 2.37c is buggy. Version 2.38d works.
- On an Alliant running Concentrix, cc (even without optimization) generates
incorrect code. You have to use gcc.
For all machines, Use "make check" to check that gzip was compiled correctly.
WARNING: on several systems, compiler bugs cause gzip to fail, in
particular when optimization options are on. See the section "Special
targets" at the end of the INSTALL file for a list of known problems.
For all machines, use "make check" to check that gzip was compiled
correctly. Try compiling gzip without any optimization if you have a
problem.

library, but this would degrade performance. In the meantime, you can
look at the sample program zread.c.
The library should have one mode in which compressed data is sent
as soon as input is available, instead of waiting for complete
blocks. This can be useful for sending compressed data to/from interactive
programs.
- Make it convenient to define alternative user interfaces (in
particular for windowing environments).
