checkpoint 1990 Makefiles

Added Makefiles for 1990 entries.

In a some cases the source code was modified.

Modified 1990 README.md files.

In some cases the program still cannot be compiled.

     Some C preprocessors get confused about single quotes in certain cases.
     In particular, the following source line:
 
-   Cb12(ase(bco(acp(bi(acp(bcp(acp(bpl(aqu(bqu(A))))))))))))))))))))))))))))))
+       Cb12(ase(bco(acp(bi(acp(bcp(acp(bpl(aqu(bqu(A))))))))))))))))))))))))))))))
 
     may need to be changed to:
 
-   Cb12(ase(bco(acp(bi(acp(bcp(acp(bpl('A'))))))))))))))))))))))))))))
+       Cb12(ase(bco(acp(bi(acp(bcp(acp(bpl('A'))))))))))))))))))))))))))))
 
     if your C preprocessor botches single quotes in cpp expansions.

     We changed the alias that the author's suggested alias from a
-    C-shell alias to a Korn shell alias because many C-shells
+    C-shell alias to a zsh alias.
-    did not allow Stig Hemmer's form of aliasing.  (The error 
-    may have also been due to some uucp site corrupting his 
-    entry) Below is the author's 'how to compile' sections as 
-    mailed to us:
-
-    ---how to ANSI compile---
-    Xecho alias c cc -E -o o.c shst.c -"\''Dc=main(){printf("\"N%sested E
-    Ccomments allowed.\\n\",'/*/*/0*/**/'1?\"\":\"o n\"");}'\'';cc -o c o.c'
-    Xsource shst.c"|csh
-    ---how to common compile---
-    Xecho alias c cc -E -o o.c shst.c -"\''Dc=main(){printf("\"N%sested E
-    Ccomments allowed.\\n\",'/*/*/0*/**/'1?\"\":\"o n\"");}'\'';cc -o c o.c'
-    Xsource shst.c"|csh
 
     Note that shst.c is renamed to stig.c in the distribution.
 
-    Producing an equivalent C-shell alias or /bin/sh function
-    is left as an exercise to the reader.
