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.

Return non zero status for an invalid option.
Remove "NEWFILES" from os2/gzip.def for Borland C++ on OS/2.

Don't display the output name when decompressing except with --verbose.

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
Let zmore act as more if the data is not gzipped.
By default, display output name only when name was actually truncated.
Use absolute path names in gzexe'd programs for better security.
In gzexe, use chmod 700 instead of 755 and don't gzexe tail,rm,etc...
Update vms/gzip.hlp.
Added a note about the fast options (-1 to -3) in algorithm.doc.
Improved man page for zgrep.

Save the original name by default.
Allow gunzip --suffix "" to attempt decompression on any file
regardless of its extension if an original name is present.
Add support for the SCO compress -H format.
gzip --fast now compresses faster (speed close to that of compress)
with degraded compression ratio (but still better than compress).
Default level changed to -6 (acts exactly as previous level -5) to
be a better indication of its placement in the speed/ratio range.
Use smart name truncation: 123456789012.c -> 123456789.c.gz
