+Subject: IOCCC 1992 - a bug
+
+Dear Judges,
+
+albert.c (even in its fixed form) still has a bug. Although I don't
+remember the number that exposed the bug (afair, resulting in coredump)
+in albert.orig.c that has been fixed in albert.c,
+
+I've found a number exposing another bug: 10000000001 (that's 9 0's).
+Both albert and albert.orig loop without printing anything, although
+the first factor is 101 and is usually found in an instant.
+```
+
+The `albert.c` file is the fixed file, where as the `albert.alt.c`
+is file before aookying Leo Broukhis' fix.
+
+To compile this alternate version:
+
+    make alt
+
+Use `albert.alt` as you would `albert` above.

     This entry is a nice play by the rules. It can use curses, if the
     SDL graphic library is not present, and is quite good at that,
     but the colors used in graphic mode (16 bit depth) are unfortunately
     less than dazzling. We could not test this entry in DOS mode.

+## Judges' comments
+
     Try copying the source to a new file and changing around the
     order of the lines.  Does it produce the exact same output?
 
     By changing the order of the source, figure out in how many different
     ways this program can transform input to output.
 
-    NOTE: The entry has been modified for portability reasons.  The
-          original source may be found in the westley.orig.c file.
-
     This assortment obfuscated lines takes position-independant code
     to a new level!  :-)

+
+To compile this alternate version:
+
+    make alt
+
+Use `hoyle.alt.c` as you would `prog` above.

+## Judges' comments
+
     This obfuscation functions at several levels.  Note the clever
     use of use of #defines.  The do(if,else) #define, for example,
     is delightful.  The code itself contains a bunch of curves
     designed to throw you off axis.  :-)
 
-    The original source may be built by:
-
-	make hoyle.orig
-
-    A missing newline was added and tab stops were converted to standard
-    8 character width in the new code.

+# Regarding individual entries:
+#
+# IOCCC winning entry code may not work on your system.  Even with standards,
+# conditions and build environments change, especially when it comes to more
+# extreme code such you might find in an IOCCC winner.  Moreover, what was
+# allowed and liked in one IOCCC contest may no longer be liked/allowed in
+# later IOCCC years.
+#
+# Corrections on winning author and fixing typos in remarks are VERY WELCOME.
+#
+# GitHub pull requests are welcome:
+#
+# If you have a patch that might make running an entry work in modern Unix-like
+# environments, please create a GitHub pull request for the IOCCC judges to
+# consider.
+#
+# Suggestions and corrections regarding Makefiles, winning author information,
+# fixing typos in remarks, and code patches are welcome via opening a GitHub
+# issue or better yet, by creating a GitHub pull request for the IOCCC judges

+# Corrections on winning author and fixing typos in remarks are VERY WELCOME.
