Simply the Makefile header.
Refer to the //www.ioccc.org/bugs.md URL (that will eventually exist).
Now using CC BY-SA 4.0 License to how you may share and adapt the
Makefile.
I had to make a new function (also four letter word to match the
formatting) that is allowed to have an int as the third arg to it. I
chose the word pain :-) as it's a pain that clang is this way without
providing any option to disable it.
Note that the arg must be an even number of digits. This threw me off
until I read the README.md because on different systems I got different
results for odd number of digits args despite the fact there should be
no difference here as the diff shows.
The commit 00ae59cd47 had a
mistake that introduces changes to Makefiles for 1996 thru 2020
that should not have been included.
This change reverses these intermediate changes until
the given year's Makefiles are ready.
There is one exception:
$ find . -name '*.hint' -execdir git mv '{}' README.md \;
git statufatal: destination exists, source=1992/albert/albert.hint, destination=1992/albert/README.md
Looking at the two files they differ quite a bit so I've not changed it.
I'll bring this up on GitHub.
We we move 1988-2004 entries from all of a year's winning entries
in a single directory to each winner being in their own sub-directory
under the given year directory.
