## Alternate code:
### INAFIAB - it's not a feature it's a bug :-(
The alternate code allows SOME of the features to work with clang but some of
the code it generates (see [compile.sh](compile.sh), which does not use this
version) is not compilable even in gcc let alone clang. Nevertheless the main
feature should work for clang.
There might have been a segfault that was fixed in the original code but as we
no longer know what condition or conditions caused this we cannot be sure. It
seems like, according to various files, that `ver1` and/or `ver2` also have this
problem but we also do not know about the status of this. See
[bugs.md](/bugs.md) for more information.

Warning: in the past, values of LEVEL>8 have been known to cause compilers (and

MacBook Pro with the M1 chip and found that LEVEL > 6 caused problems.
Back in 1995, values of `LEVEL>8` caused some compilers (and in one case a
system) to crash during compilation. In 2023 with modern systems this is not
really a problem.
Back in 1995 we also suggested that for a bad/slow time to try `LEVEL=15` but
this is not a big deal in 2023 either.

### STATUS: main() function args not allowed - please help us fix
Although [Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) fixed this for
some of the versions that are generated (see below tip) it will not work for all
with the clang compiler (gcc works fine) and in some versions of clang it will
not work at all due to yet another defect (see below also).
This entry is a big problem for clang due to the way it is designed. Earlier a
change was made to let it compile with clang but although it appeared to work
with gcc, all generated versions (see the README.md for details), this was
either a mistake or it no longer does.
Thus the original was copied and this does not work at all in clang. It is very
easy to get the first one or two to work with clang but the others result in
compilation failures even besides clang.
The problems with clang is that it does not allow `int` for any arg in `main()`
except the first one, argc, and some versions of clang do not even allow a
fourth arg at all (0, 2 or 3 args only).
Cody noted that trying to fix it in some cases causes a segfault and in other
cases it fails to generate some of the files (others are okay) at all (empty
files).
There is another change that was thought up on 08 July 2023 which allows for
another version to be compiled with clang but it causes some of the versions to
not be correctly generated (whereas the current way does generate all files but
is not compilable with clang) so for now this is not in. If it is put in it will
be an alternate version.
Some versions of clang have an additional defect where in additional to forcing
the args of `main()` to be of type `int` (for first arg) and the rest to be
`char **` it also does not allow a fourth arg to main(). This in fact is part of
the change thought up on 08 July 2023: main() calls a function which has the old
types of variables.

Cody gives these tips on the problem: `main()`'s second, third and fourth args

Cody also improved the script [garry.test.sh](1995/garry/garry.test.sh) to make
sure the program is compiled before trying to use it and he also added the
[garry.alt.test.sh](1995/garry/garry.alt.test.sh) script to use the alt version,
though the alt version is not as important as alt code in other entries.
The reason the alt script was added rather than using an environmental variable
to specify which one to use is to make it easier on the user as typing
`GARRY=garry.alt ./garry.test.sh` is not as simple (even though simple) as just
running `./garry.alt.test.sh`.

Cody added alt code that fixes the problem where in German 'v' sounds like 'f'

'fier' to '4' when the word is 'vier'. Originally this was updated in the
original code but it was noticed that this caused _other_ words to be incorrect
so it was set as an alt version since the code was already there. It might also
be considered a feature and not a bug so an alt version is the better way to go
about it. Using both allows one to experience different capabilities and also

Cody also added two scripts, [en.sh](2012/kang/en.sh) and

In the German script it uses the umlaut and also does it without the umlaut (add
an 'e'). Both scripts can use either version to see the differences. See the
README.md file for details.

and also enjoy or appreciate the entry even more, given how simple the

Cody also added five scripts: [en.sh](2012/kang/en.sh),
[de.sh](2012/kang/de.sh), [en.alt.sh](2012/kang/en.alt.sh) and
[de.alt.sh](2012/de.alt.sh) which count from 0 through 13 in English and German

In the German scripts it uses the umlaut and also does it without the umlaut

either version but the `.alt.sh` versions default to the `alt` version whereas
the other defaults to the submitted entry. See the README.md for details.
The fifth script, [try.sh](2012/kang/try.sh), runs a sequence of commands to
show different languages and numbers.
