Updated the README.md files.
Renamed shapiro/shapiro.orig.c -> shapiro/shapiro.alt.c. This is one of
the exceptions where we have the alt version as this alt version is not
actually in the archive tarball (there are other exceptions for various
reasons).
Unfortunately some entries will either not compile under macOS or not
run correctly. We used a patch from Yusuke Endoh for
1985/applin/applin.c. Thank you Yusuke! This is actually the entry that
does not work right under macOS but it does under linux.
Update main README.md with links.
Update a number of other README.md files with typos and other fixes and
improvements (including fixing invocations and adding a 'Try:' section
to match later year README files).
Update various Makefiles to add notes and to make some entries compile
(in some cases, those that require -traditional-cpp, they will not
compile under clang and we note this).
Update archive/archive-1985.tar.bz2. Why? Because the purpose of the
archive/ files are for the original files and some of the files in there
were not original. See the files 1985/lycklama/lycklama.orig.c and
1985/shapiro/shapiro.orig.c which in the tarball do not have the .orig
added to the name.
