Landon Curt Noll c78bda6c0f update tarballs due to recent commits
The commit a1c86c8a7a modified
the navigation bars to include "Original C", so all tarballs
had be update, sorry (tm Canada 🇨🇦).  In particular:

The navigation bar for a winning entry now has a "_Original C_" link
(between the ✅ and the Inventory on the right hand side) so that one
may easily view the original C code that was submitted for IOCCC judging.

In addition, a number of other commits since that time
modified other winning entries.

Ran `make update` to perform the above.

To build:

    make all

There is an alternate version for those with a compiler that support -traditional-cpp. See Alternate code below.

To use:

    ./wall

Alternate code:

This version is the original but which can be used if you have a compiler that supports the -traditional-cpp option.

Alternate build:

        make alt

Alternate use:

Use wall.alt as you would wall above.

Judges' remarks:

The original version did not have a ';' character in the first line. This caused a number of System V C pre-preprocessors to gripe about a syntax error.

This program is a masterpiece of obfuscation and humor. Larry Wall (the hacker who gave us rn and patch, etc.) asks you to compile and consider the warning message generated by the C compiler. Then execute the program and type characters into its standard input. You will see why the compiler documents the program.
