+
+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) added an alternate
+version which does what the program did with gcc < 2.3.3. To use:
+
+```sh
+make alt
+```
+
+Use `lmfjyh.alt` as you would `lmfjyh` above. Note that other code could also be
+done with this bug; see the author's remarks for more details.

 There's more than one way to get around disk quotas. :-)
@@ -106,7 +113,7 @@ megabyte of source code file can be compressed to 64 kilobytes.
 One might easily think that the program could be compressed to a
 single byte by writing a one character long preprocessor directive
 in the source file and defining the actual source code in the
-command line, eg. `cc hello.c -DX='main(){puts ...'`.  With this
+command line, e.g. `cc hello.c -DX='main(){puts ...'`.  With this
 method nothing is gained, since the compiling commands must be
 stored in a file, and that takes even more space than writing the
 code in a source file as presented in listing 1.
