By chance I looked at this entry again and it immediately popped into my
head how to get it to work. Except for the one in main() the ints need
to be longs. This will now compile and work as expected both with
64-bit and 32-bit compilation.
Disabled make alt and updated .gitignore.
This was done by changing the types of the args in main() to be int and
char ** respectively and (where necessary) casting the argv (V) to int
which was the previous type.
I also noted that prior to and after the fix certain invocations
segfaulted though Yusuke Endoh did not have this problem (I linked to
his analysis of the entry).
We we move 1988-2004 entries from all of a year's winning entries
in a single directory to each winner being in their own sub-directory
under the given year directory.
