My original fix no longer worked, at least with clang in some systems,
because of more strictness in the compiler wrt implicit ints. As the
code does not use the Makefile but rather 'cc' (and in an unusual way)
'main()' now has an explicit int.
Also, what was previously documented as a bug to be fixed has been
changed to INABIAF as it was documented already. Thus it should not be
fixed. In fact the judges originally noted that if one specifies the
triggering input they should expect an infinite loop and compilation
failure.
In some cases if one were to modify the C code (possibly the same with
the script) in certain ways the program would fail to work even after
changing the code back. Trying to figure out what to put in bugs.md and
on a hunch, changing the fubar.sh script (in particular the ex(1) part)
remedies the problem (or so it seems from the various tests I have
performed including some that caused a problem). In particular:

The C code was also changed to make it even more like the original code.
There were some which cannot be compiled under clang. One entry we used
a patch from Yusuke Endoh to get the entry to compile; thank you Yusuke
for your assistance! Another one we used a patch from Yusuke (thank
you!) but I further fixed it so that it would work with clang. It had to
be done: IOCCC Tetris has to work! This was done by changing the
environment arg to main() to be a char * in main() itself rather than a
char **. Using a char ** in main() third arg got it to compile but only
one key worked with clang so I changed it to be not the third argument
but a regular char * in main(). **a (third arg) evaluated correctly but
*a[1] and onward was actually part of the environment. Again IOCCC
Tetris has to work!
I also fixed fubar to work which took a few tweaks.
README.md files were also updated.
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.
