• Delays in forming the 2003 contest pushed the start of the 17th International Obfuscated C Code Contest to 07-Jan-2004 00:00 UTC. Therefore the 17th IOCCC started in 2004, not 2003.

• We did not hold an IOCCC in 2002 due to delays in the 2001 contest release.

Leo used the unobfuscated version, with a certain limitation to fix the bug which may be found in albert.fix.c. Sorry about being vague, but that is about all we can say and not spoil it.

Around the same time, were were notified by Nathan Sidwell (who lives outside the US) that his source available on the Web as well. The source at that site also no longer exists.
  
  Update: We were told that Google has a comp.lang.c archive with a copy of the source ported by Nathan Sidwell.
