# A few compilers have broken optimizers and thus you may #
# not want anything. # 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
