The entries 2004/hibachi and 2005/mynx have unobfuscated code now. 2004/hibachi has a configure script that is used along the lines of the original entry (with some adjustments and fixes) and the hibachi.alt.c had to have ctype.h included too. The directory src/localhost was copied to src-alt/localhost but the rest of src/ was from Anthony. The Makefile had to be updated to build this version. 2005/mynx does have a configure script but it is, just like the original entry, unused and so the unobfuscated (in source-alt/) is also unused. The mynx.alt.c was changed to mynx.alt2.c and the unobfuscated code was made mynx.alt.c. Updated manifest, rebuilt .entry.json and index.html files. After a question is answered and taken care of (in one of 199[1-3]/ant - not sure which one) issue #2513 can possibly be closed as complete (though the manifest updates will have to be looked at more when 2004 and 2005 are reviewed).

* ioccc.c IOCCC 2001 Source Size Rule
|
|
*
|
|
* Public Domain 1992 by Anthony Howe. All rights released.
|
|
*
|
|
*
|
|
* SYNOPSIS
|
|
*
|
|
* ioccc [-s]
|
|
*
|
|
* DESCRIPION
|
|
*
|
|
* Taking input from standard input, apply the IOCCC Source Size
|
|
* Rule for 2001. The program's offical length is written to
|
|
* standard error. Also filter out C comment blocks sending the
|
|
* modified source to standard output.
|
|
*
|
|
* The 2001 Source Size Rule is:
|
|
*
|
|
* Your entry must be <= 4096 bytes in length. The number of characters
|
|
* excluding whitespace (tab, space, newline, formfeed, return), and
|
|
* excluding any ';', '{' or '}' followed by whitespace or end of file,
|
|
* must be <= 2048.
|
|
*
|
|
* The -s option siliences standard output.
|
|
*
|
|
* NOTE the overall length is not counted since this can be checked
|
|
* with "ls -l".
