-it did:

-```c

-no longer works to create `getuid()` and `getgid()`. The second is that
-
-```c
-for/*/(;;);/*/k()){O/*/*/c);
-```
-
-cannot form `fork())` in modern C compilers. What is quite fun is that the cpp

+## [1986/wall](1986/wall/wall.c) ([README.md](1986/wall/README.md]))
+
+We used a patch provided by [Yusuke Endoh](/winners.html#Yusuke_Endoh) to make
+this work with gcc (in particular the patch uses `strdup()` on two strings).
+Thank you Yusuke! [Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) fixed
+this so that it does not require `-traditional-cpp`. This took a fair bit of
+tinkering as this entry *is* strange. The original code is provided to allow one
+to easily see how different C was in those days. See below for details. Thank
+you Cody for your assistance!
+
+
+## [1987/wall](1987/wall/wall.c) ([README.md](1987/wall/README.md]))
+
+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) made this safer by
+using `fgets()` instead of `gets()`. This prevents an annoying and potentially
+alarming warning at compiling, linking or runtime.
+
+
+## [1987/westley](1987/westley/westley.c) ([README.md](1987/westley/README.md]))
+
+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) fixed this for modern
+systems. The problem was 'assignment to cast is illegal, lvalue casts are not
+supported'. For the original file see below. Thank you Cody for your assistance!
+
+## [1988/dale](1988/dale/dale.c) ([README.md](1988/dale/README.md]))
+
+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) fixed this for modern
+compilers. There were two problems to address. One was that the entry required
+`-traditional-cpp` (which <strike>not all compilers support</strike> `clang`
+does not support) which Cody fixed. It needed that option because of two things
+it did:
+
+```c
+#define a(x)get/***/x/***/id())
+
+/* ... */
+
+p Z=chroot("/");L(!a(u)execv((q(v="/ipu6ljov"),v),C);Z-=kill(l);
+
+/* ... */
+
+case_2:L(!--V){O/*/*/c*c+c);wait(A+c*c-c);L(!Z)f(A,"\n",c);return(A*getgid());};C++;
+```
+
+no longer works to create `getuid()` and `getgid()`. The second is that
+
+```c
+for/*/(;;);/*/k()){O/*/*/c);
+```
+
+cannot form `fork())` in modern C compilers. What is quite fun is that the cpp
+can!
+
+The other problem was that modern compilers do not allow directives like:
+
+```c
+#define _ define
++#_ P char
++#_ p int
++#_ O close(
+...
+```
+
+so Cody changed the lines to be in the form of:
+
+```c
+#define foo bar
+```
+
+## [1988/isaak](1988/isaak/isaak.c) ([README.md](1988/isaak/README.md]))
+
+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) fixed this to work for
+modern systems. The problem was that the important function, a redefinition of
+exit(), was not being called in main(). See below notes for the original,
+alternative version.
+
+The original version is in [1988/isaak/isaak.alt.c](1988/isaak/isaak.alt.c).
+
+## [1988/phillipps](1988/phillipps/phillipps.c) ([README.md](1988/phillipps/README.md]))
+
+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) fixed this for modern
+systems. It did not compile with clang because it requires the second and third
+args to main() to be `char **` but even before that with gcc it printed random
+characters. After fixing it for clang by changing main() to call the new
+function pain() (chosen because it's a pain that clang requires these args to
+be `char **` :-) ) with the correct args it now works. Thank you Cody for your
+assistance!
+
+
+## [1988/spinellis](1988/spinellis/spinellis.c) ([README.md](1988/spinellis/README.md]))
+
+An alternate version was provided by Cody for this so that it works for
+compilers like clang.
+
+## [1989/fubar](1989/fubar/fubar.c) ([README.md](1989/fubar/README.md]))
+
+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) got this to work with
+modern systems. The main issues were an `#include` had to be added and fixing the
+path to files referred to in the code was also needed.
+
+
+## [1989/jar.2](1989/jar.2/jar.2.c) ([README.md](1989/jar.2/README.md]))
+
+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) fixed this to work with
+modern compilers. Modern compilers do not allow code like:
+
+```c
+#define D define
+#define a include
+
+#D foo bar
+#a <stdio.h>
+```
+
+He notes that there _is_ a way to get it (or something close to it) to work. Do
+you know how?
+
+## [1989/ovdluhe](1989/ovdluhe/ovdluhe.c) ([README.md](1989/ovdluhe/README.md]))
+
+Cody provided an alternate version based on the author's remarks. See the
+README.md for details.
+
+## [1989/paul](1989/paul/paul.c) ([README.md](1989/paul/README.md]))
+
+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) fixed a segfault under
+macOS. The problem was that the int (from `#define f`) should be a long. This
+became apparent when he was using lldb and saw that the type of a pointer was
+long. Thank you Cody for your assistance!
+
+## [1989/robison](1989/robison/robison.c) ([README.md](1989/robison/README.md]))
+
+Yusuke Endoh fixed this to compile under modern systems.
+
+
+## [1989/tromp](1989/tromp/tromp.c) ([README.md](1989/tromp/README.md]))
+
+We used a patch from [Yusuke Endoh](/winners.html#Yusuke_Endoh) 
+to get this to compile under gcc. Thank you Yusuke for your assistance!
+
+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) got this to work with
+clang by further changing the variable `a` to be not the third argument to
+`main()` and instead be a variable declared in `main()`.
+
+Cody also bug fixed it so that the high score file would work (it was not even
+being created) and after this making sure the terminal stayed sane (the letter
+`u` could not be typed and echo was disabled outright after the segfault fix /
+high score file was reinstated). We thank you for your assistance Cody (he
+cynically notes that he did it because tetris just has to work)!
+
+
+## [1989/westley](1989/westley/westley.c) ([README.md](1989/westley/README.md]))
+
+Cody got this to partly work with clang. As there are some important notes on
+this in the README.md file we have left the details in that file, at least for
+now. Perhaps the [bugs.md](bugs.md) file is a better place but this can be
+decided later.
+
+
+## [1990/baruch](1990/baruch/baruch.c) ([README.md](1990/baruch/README.md]))
+
+Cody added an alternate version which allows certain compilers to compile the
+code, based on the author's remarks.
+
+## [1990/cmills](1990/cmills/cmills.c) ([README.md](1990/cmills/README.md]))
+
+Yusuke got this to work in modern systems (it resulted in a bus error).
+
+To prevent alarming warnings at linking or runtime Cody made the entry use
+`fgets()` rather than `gets()`. He notes that another option would have been to
+redirect `stderr` to `/dev/null` but he did not think of that at the time.
+
+For the original code see the [1992 archive](/archive/archive-1990.tar.bz2).
+
+
+## [1990/dds](1990/dds/dds.c) ([README.md](1990/dds/README.md]))
+
+[Yusuke Endoh](/winners.html#Yusuke_Endoh) fixed this for modern systems. Thank
+you Yusuke!
+
+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) removed the erroneous
+prototype to `fopen()` and made this use `fgets()` instead of `gets()` to make
+it safer and to prevent an annoying and potentially alarming warning at
+compiling and/or linking and/or runtime. Thank you Cody for your assistance!
+
+
+## [1990/jaw](1990/jaw/jaw.c) ([README.md](1990/jaw/README.md]))
+
+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) fixed the script to
+work properly in modern environments (to do with PATH not having '.' in it). He
+notes that with an invocation in the try section will with macOS show
+what appears to be an error message but is actually okay. He gives more
+information in the [bugs.md](/bugs.md) file. Thank you Cody for the help and
+notes!
+
+NOTE: as `btoa` is not common we used a ruby script from [Yusuke
+Endoh](/winners.html#Yusuke_Endoh). Thank you Yusuke for your implementation of
+`btoa`!
