Subject: [PATCH 1/6] Change how 1985/lycklama is built + fix typo

Now that we have the original code in lycklama.orig.c we can have what
would more appropriately be an alternate version in lycklama.alt.c which
is now done.

Typo fix was really unfortunate: it was in an example command to try
which would have failed to work as the name was wrong.

Subject: [PATCH 2/6] Mass .gitignore update for .orig.c files

Due to the fact we now have .orig.c files and thus the possibility of
winner.orig or prog.orig being built I have updated all the .gitignore
files so that these files ignored. This was done with the following
shell commands, for reference:

    for i in $(find 19* 200* 201[0123] -mindepth 2 -maxdepth 2 -name .gitignore) ; do echo $(dirname "$i"|sed -e 's,[0-9]\{4\}/,,g').orig >> "$i"; done
    for i in $(find 201[4-9] 2020 -mindepth 2 -maxdepth 2 -name .gitignore) ; do echo prog.orig >> "$i"; done

and the two commands is because it was only in 2014 that the winning
entries were renamed to prog so prog.orig is the correct glob.

Subject: [PATCH 3/6] Restore silencing warnings in macOS

As besides the entries that are not supposed to compile/cannot compile
due to architectural limitations all the entries can compile in macOS
(though some do not work - yet(? I have plans to work on more later)) it
was not necessary to not silence the warnings after all as the entries
that don't work will be easy to identify ('they don't work' :-) ) so I
can just do make CSILENCE= all in the directory of those entries which
solves the problem I had originally thought of.

Some of the Makefiles have retained other changes I had to make
yesterday to get the entries to work with clang in linux but most of
them were either not changed or were made better with the rollback of
the commit that originally silenced warnings.

Now work on silencing warnings for linux can be done.

Subject: [PATCH 4/6] Fix funny problem in alt target in 1989/westley

In linux running make ver1 and make ver2 and make ver3 (not sure about
ver0 now) there was a strange error when running the rules that meant
the code was not compiled. Thinking on it just now it very likely was
the exit code of the program causing the problem but the file was
generated so I added a '-' to the line so that the rule will proceed to
try and compile the code.

Subject: [PATCH 5/6] Minor fixes in 1984/anonymous

The anonymous.c no longer triggers a warning that can't be disabled
(added 'int' before 'i' which is how it was in the original anyway).

Minor fix in the README.md.

 ### Alternate code:
 
-The alternate code, [decot.alt.c](decot.alt.c), is the original code that
-requires `-traditional-cpp` and will also run afoul with clang's requirement for
-the second and third arguments to main() being a `char **` (the fixed version's
-main() only has one arg, an int). It is a minor fix to Yusuke's fix. Thank you
