Get 1989 entries to compile

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.

-	Passes lint, but not with the strictest options, for it
-	contains some "null-statements", as well two identifiers
-	which are, if compilers only take 6 characters, the same.  It
-	also uses write(2), so not totally system independent.
