My name is Kenji Ishii.
I found gzip bug(or differ from 1.2.4a) about gzip 1.3

At first when using gzip version 1.3 ,link file is not
ignored .

 > ls -l
total 8
-rw-rw-r--   1 ishii    cad            0 Oct  3 10:02 test
lrwxrwxrwx   1 ishii    cad            4 Oct  3 13:23 test.link -> test

===== gzip version 1.2.4a ================

 > gzip test.link
gzip: test.link is not a directory or a regular file - ignored


===== gzip version 1.3 ===================
 > gzip test.link  
 > ls
test           test.link.gz

 > gzip -d test.link.gz
 > ls -l
total 8
-rw-rw-r--   1 ishii    cad            0 Oct  3 10:02 test
-rw-rw-r--   1 ishii    cad            0 Oct  3 10:02 test.link


I think that gzip1.2.4a is very stability but it has any
problem using huge file .

The gzip1.2.4a problem is that 
Doing file listing from DLT tape that archived more than 8GB
file,it has following error without completing.
( it is used gzip1.3 when archiving to DLT( gtar zcf /dev/rmt/0 )

 > gtar ztvf /dev/rmt/0
gzip: stdin: invalid compressed data--length error
gtar: Child returned status 1
gtar: Error exit delayed from previous errors

I read NEWS file from gzip1.3 source files and many function 
was added from 1.3 version ,especially about huge file.

We want to use gzip1.3 version and if the problem was fixed
on gzip1.3 ,It is very appreciate.

Major changes from 1.2.4 to 1.3
* Add support for large files, e.g. files larger than 2 GB on Solaris 2.6.
* Adjust file size listing format for files larger than 10 GB.
* New command `zless'.
* `zdiff' now reports exit status like `diff' does.
* `zcat' is now always called `zcat', not `gzcat'.
  Similarly for `zdiff', `zgrep', `zmore', `znew', `zforce'.
* Warn about a compressed file's trailing zeros only if verbose,
  for compatibility with recent versions of GNU tar.
* Conform to changes to GNU makefile standards.
* Port to Autoconf 2.13.
* Convert to Automake.
* Fix bugs in the following areas:
  - files larger than 4 GB
  - security hole involving symlinks from /tmp
  - security hole involving long file names
  - permissions bug when compressing a symbolic link to a file
  - core dumps
  - concatenated compressed files on INBUFSIZ boundaries
  - porting bugs on hosts with signed chars
  - porting bug with upper and lower case
  - porting bug for hosts that reserve the names `basename' or `warning'
