A line for one entry was in the wrong entry.

I added that I'm working on them (with some humour injected there) but
others may try too .. if they are okay making people very sad :-)

Added more information / examples in some of the status sections and
possibly some of the entries that are listed.

# List of Statuses - Please read before fixing (you may skip if you're only interested in entries with known issues)
Entries below have one of the following _Status_ values.
Please see the text below for more information.
[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) has been working on
resolving these issues and has fixed many but you're welcome to have a go at it
too (though he'll be very sad if he doesn't have a chance at it first :-( so you
might want to hold off for now :-) .. or not :-) ). He hopes to have most of the
remaining entries resolved in the near future but nevertheless if you're okay
making people very sad you may have a go at the entries :-) He'll remove this
part later on.
### Status: known bug - please help us fix
This entry has a bug that needs fixing. Are you able to fix it?
We welcome your help! Please submit a [GitHub pull request](https://github.com/ioccc-src/temp-test-ioccc/pulls)
and we will be happy to credit you in the entry's _README.md_ file.
### Status: main() function args not allowed - please help us fix
This entry has a problem in that the args to main() are not of a specific type
due this being allowed in earlier C. This shows itself in some compilers like
clang. [Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) looked at the
source code of clang and reported that there is no way to override this
requirement so these entries will fail to compile with clang. That's why he in
some entries he fixed he did it by adding a function called `pain()`. :-)
Note for macOS users: please be aware that gcc under macOS is clang despite the
fact it might appear to be gcc: no symlink and both gcc and clang exist but the
gcc is clang which you'll see if you run `gcc --version`.
A tip and some fix methods from Cody: in the older days args to main() not given
a type were implicit ints but when they're required to be char ** this can cause
a problem. In some cases Cody was able to use a char * inside main() (see
[1989/tromp/tromp.c](1989/tromp/tromp.c) and
[1986/holloway/holloway.c](1986/holloway) for two examples though done slightly
differently). In other cases he was able to dereference the pointers to be used
like an int. He used other various techniques to get them to compile. In some
cases this introduced a problem but typically if not always that problem exists
with compilers that are less strict.
Request: For one-liners please keep the file one line if at all possible! If it
needs an include you can update the Makefile `CINCLUDE` variable. For instance
if it needs `stdio.h` you could do `-include stdio.h`. Please leave a space
after the `=` in the Makefile!
We welcome your help! Please submit a [GitHub pull
request](https://github.com/ioccc-src/temp-test-ioccc/pulls) and we will be
happy to credit you in the entry's _README.md_ file.
### Status: Compiled executable crashes - please help us fix
While the entry can compile, the resulting executable sometimes or always crashes.
We welcome your help! Please submit a [GitHub pull request](https://github.com/ioccc-src/temp-test-ioccc/pulls)
and we will be happy to credit you in the entry's _README.md_ file.
### Status: Requires a compiler supporting -traditional-cpp - alternate code requested
This entry needs a compiler that support `-traditional-cpp`. `gcc` supports this
but `clang` does not.
Please be advised that, as noted above, gcc under macOS is actually gcc even if it
looks like it's gcc (the programs are the same, they're not symlinks but both
are clang).
If you do wish to provide an alternate version of the program that does not need
compiler supporting -traditional-cpp you are welcome to summit such code via a
[GitHub pull request](https://github.com/ioccc-src/temp-test-ioccc/pulls) and we
will be happy to credit you in the entry's _README.md_ file.
