Update 2014/deak alt code + format/typo checks

The alt code now lets one redefine the coordinates (which was
deliberately not obfuscated by the author for this purpose). A casual
look at the code would make one think it's not an alt code but it's a
fixed version that the author provided if a certain statement was not
true (see README.md file) so the only thing that is different is that
there is the #ifndef..#define..#endif of coordinates and the fix to
compile (missing a return value, possibly also fixed in the README.md
file, and an added #include <stdio.h> for putchar(3)).
