Simply the Makefile header.

Makefile.
main() had one arg, a char *, and this is against clang requirements.
There was no inclusion of setjmp.h and so the longjmp() function
implicitly returned int and was allowed to take the wrong number of
args. It should return void however and this caused a problem with
binary expressions. The comma operator has been used for this but it
might be a problem in that by having ,1 after each it will make
expressions that could turn out to be false to be incorrect.
The longjmp() was being called with one arg which was an element of an
int[4][1000]. This is obviously incorrect but at some point it worked.
Without the prototype this is not a problem but both before (gcc) and
after the compiler fix (with gcc and clang) it did not work with linux
(in this case fedora) or macOS. The code as it now stands has the same
problem as it did before the compilation fix: it lets you input a bet
but then it does not accept any input after that; it prints nothing more
but it should print a new hand. This issue has been put in bugs.md.
My guess (in my tired head) is it has to do with the abuse of the
longjmp() and/or the comma operator making the expressions always 1 (at
least that side of the expression, thus if it gets to the longjmp() part
it will always be 1). Perhaps it should be ,0? I don't know but I might
try that next (I would guess it should be whatever an implicit int would
return without a return statement but that's just a guess). But given
that it stops working at the same spot perhaps it's not the comma
operator. Maybe the function needs to be broken up into several but I
don't know and that might or might not be worth the effort.
Finally it returned main() itself but now it returns poke() which has
the body of what main used to be.
See bugs.md for more details.
The commit 00ae59cd47 had a
mistake that introduces changes to Makefiles for 1996 thru 2020
that should not have been included.
This change reverses these intermediate changes until
the given year's Makefiles are ready.
There is one exception:
$ find . -name '*.hint' -execdir git mv '{}' README.md \;
git statufatal: destination exists, source=1992/albert/albert.hint, destination=1992/albert/README.md
Looking at the two files they differ quite a bit so I've not changed it.
I'll bring this up on GitHub.
We we move 1988-2004 entries from all of a year's winning entries
in a single directory to each winner being in their own sub-directory
under the given year directory.
