A number of rules have been moved from entry `Makefile`s into the `1337.mk` include file to make it easier for these common rules to be updated or modified globally (by modifying the `1337.mk` include file). The entry level `Makefile`s are now similar in form to the /Makefile.example](https://github.com/ioccc-src/mkiocccentry/blob/master/Makefile.example) file from the other repo. The following make rules were moved into the `1337.mk` include file: - `make indent.c` - `make install` - `make diff_orig_prog` - `make diff_prog_orig` - `make diff_alt_prog` - `make diff_prog_alt` This simplifies the entry level `Makefile`s so that they mostly reflect the specifics of the particular entry. Mentioned in FAQ 4.2, that the make diff rules are in the `1337.mk` include file. Fixed invalid TAB character in `faq.md`. Removed `make clean` directives that removed `indent.c`. This file is now removed via `make indent_clean`, a clean rule that also removes `indent.c`. Removed `make clobber` directives that removed sandwich, This file is now removed via `make indent_clobber`, a clean rule that also removes `sandwich`. Added `make indent_clean` and `make indent_clobber` rules into the top level `Makefile` and the year level `YYYY/Makefile`. Performed `make quick_www` to accomplish the above and to test under macOS.
Fourth International Obfuscated C Code Contest
View the index.html web page for the given winning entry for information on how
compile it and how to run the winning program. Look at the winning source and
try to figure how it does what it does! You may then wish to look at the
Author's remarks for even more details.
The rules for 1987 suggested even more
categories than in 1986.
Hints for what to do and not to do were also given in the rules.
For example, a simple excessive abuse of /lib/cpp was discouraged unless the
abuse was unusual. The mailboxes for the contest were moved from nsc to amdahl.
The practice of posting a preliminary set of rules for the next year was started
this year.
Rules and results were posted to comp.lang.c and comp.unix.wizards with an announcement in news.announce.important. Micro/Systems Journal published the 1987 winning entries. Mary Ann Horton included a version of the 1987 winning entries in an appendix of her C book Portable C Software International Edition (published under the name Mark R Horton). The first announcement of winning entries at the Summer 87 USENIX was helped by a small fly that danced all over the foils.
