Two bugs:

1) I forgot to include the correct version of the code

2) the version I had created a few files with '/' in their names; this
   slightly nastier creates 10,648 files with only letters.

#include <unistd.h>
#define b(i,v)for(int v=65;v<87;){i[f]=v++;
#define a(i)b(i,v##i)
int main(void){char f[4]={47};a(1)a(2)a(3)truncate(f,0);}}}}
