Further fix 1984/decot for clang (for linux)

Although my change of not requiring -traditional-cpp worked in macOS it
turns out one change had to be made for clang in linux which has now
been done.

 Cody fixed this to not require `-traditional-cpp` which not all compilers
 support (clang does not support it for example). Clang is also more strict about
 the args' types in `main()` and this was also a problem that Cody fixed, making

 Originally Yusuke supplied a patch so that this entry would compile with gcc -
 but not clang - or at least some versions.
