Judges' comments:

We changed the alias that the author’s suggested alias from a C-shell alias to a Korn shell alias because many C-shells 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.

WARNING: This program’s ‘how to compile’ is too specific to a particular shell. The obfuscation of this program to more related to shell obfuscation than C obfuscation. This type of entry will not be permitted in future contests.

Selected notes from the author:

If you like shell programming you may also admire my creative quoting. (I use echo to create an alias which when run calls cc with the -D option to create a C macro with double quotes in it. ARRRRRGGGHHH!)

The program is totally portable, but the compile commands are very shell specific so don’t be TOO mad at me if they don’t work for you.

If you want to put these commands in a Makefile you must add 4 - four - backslashes at the end on first line. (At least that’s what works here.)

If everything works correctly it create an executable named c which checks whether your compiler supports nested comments. I’ve stolen the “///0*/**/1” from somewhere so don’t give me any points for it. Of course neither ANSI nor K&R support nested comments when properly implemented, but what the heck.
