Strangest abuse of the rules: Jari Arkko Laboratory of Information Processing Science Helsinki University of Technology Otakaari 1 02150 Espoo Finland Judges notes: On many systems the compiler will not allow you to send the object file to /dev/tty. The author suggested: cc -c -o /dev/tty jar.1.c On systems that have symbolic links, we suggest: ln -s /dev/tty jar.1.o cc -c jar.1.c if your system has symbolic links. The shell script run by the makefile simply cats the .o file to the terminal which can be used as a last resort. Abuse of the rules winners usually result in a change of the rules. Starting in 1990, compiling entries must result an regular file which can be executed. Selected notes from the author: This program is (supposedly) the smallest C program able to print "Hello world.". The compilation itself produces the desired printout and the program need not be actually run. Copyright (c) 1989, Landon Curt Noll & Larry Bassel. All Rights Reserved.
