Improve my fixes to 1984/decot

To make it look more like the original but to still work with compilers
without -traditional-cpp (which clang does not support) and other
defects with clang (including one that was problematic in linux but not
macOS) code that used macros had to be modified and used directly. But I
removed the macros because of this. Now they are added back even though
they are unused, just to give it a more authentic, original look.

The thanks-for-fixes.md file was updated for this, both formatting and
otherwise, but an unfortunate thing is that another entry was also
modified in there. This is because I was aiming to just do format fixes
in 1984 in one pull request to save time but then I came across this and
decided to fix it and this should be in a single pull request.

Something I noticed is that the fix for linux clang _appears_ to not be
needed at least with clang 16.0.6 but what the difference is is just
extra warnings. I cannot imagine I changed it just for that so I have
left that change in in case there was a problem in earlier versions or
something else I do not recall. It should be noted that without the
change at least with clang 16.0.6 it appears to work just fine. It is
unclear if it should be changed back but again as I can't imagine that I
would have changed it just for warnings I think it's wiser not to.
