Fix 2001/herrmann2 for clang

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).

+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) fixed this to work with
+clang by changing the args to main() to be `int` and `char **` respectively and
+changing specific references to the `argv` arg, casting to int which was its old
+type. Thank you Cody for your assistance!

+Cody notes that [Yusuke Endoh](/winners.html#Yusuke_Endoh) does not get a
+segfault with some of the invocations (without fixing it for clang) but Cody
+does get a segfault both before fixing it for clang and after. Yusuke provides

 Be careful when staring at the source code - your eyes might cross, but
 if you concentrate on your focus you will find illumination!
