o Add support for zlib compression via ZLIB_COMP in config.h (ZLIB_COMP
and COMPRESS are mutually exclusive).
o rlecomp and zerocomp are run time options available if RLECOMP and
ZEROCOMP are defined, but not turned on by default if either COMPRESS
or ZLIB_COMP are defined.
o Add information to the save file about internal compression options
used when writing the save file, particularly rlecomp and zerocomp
support.
o Automatically adjust rlecomp and zerocomp (if support compiled in)
when reading in an existing savefile that was saved with those options
turned on. Still allows writing out of savefile in preferred format.
o In order to support zlib and not conflict with compress and uncompress
routines there, the NetHack internal functions were changed to
nh_uncompress and nh_compress as done in the zlib contribution received
in 1999 from <Someone>.
I tagged the sources NETHACK_3_5_0_PREZLIB prior to applying these
changes.
Add the ability to select the windowtype on the command line on Unix using
a new -wwindowtype option. I had thought the proposed patch could core
dump, but the default windowtype selection occurs earlier and ensures
that raw_print will always work. So, the only problem with the proposed
patch was it didn't move the linux and sco special-case code until after
the selection was made. That special-case code really should be moved to
to wintty.c, IMO since it doesn't affect other windowtypes.
Use fqname buffer 1 for restoring the save file (just like save does when
creating it) so the value won't change out from under the code in unixmain.
- Also moved a tty-specific hack in docompress_file that was causing
the 'y' response to the "keep the save file" prompt to be echoed twice.
This is an initial round of SAFERHANGUP hangup changes. It introduces
SAFERHANGUP, provides the core framework, and enables it for UNIX.
Window-port changes are provided for win/tty, win/X11 and win/gnome. Qt
changes should be forthcoming after having Warwick look at them.
window.doc is updated so windowport maintainers have an clue what needs to
be done to support SAFERHANGUP.
These changes clean up build warnings and allow the resulting "NetHack"
Application icons to be dragged around freely in the Finder, as is expected
for Mac apps.
