Description of problem:
If you attempt to save a nethack game and the recover the saved game, the
game will print version mismatch and create a new game.
Steps to Reproduce:
2.Save a game with the capital S command
3.start nethack again
4.nethack will complain of version mismatch of the old save file, and start
a new game.
Actual Results: Save file ignored, new game started.
Expected Results: Old game should be restored.
I edited the patch file, and changed the use of bzip2 to use gzip, and
removed the special options passed to the compresser, rebuilt nethack and
it worked correctly.
