Merry x-mas (c code edition)

This has been circulating the net for the past few years.
It is a remarkable piece of code.


1) Cut out the following obfuscated C-code into a file, say xmas.c
2) At your unix prompt type: "cc xmas.c"
3) The program should compile without errors, now type "a.out"
4) It will compile under DOS as well.

5) No, it does not access the file system.
   No, it does not access the network.

6) Your guess is as good as mine.

Enjoy,
Selbie
