Subject: [PATCH] Cast the trailing NULL on execl() calls
From exec(3): ?The list of arguments must be terminated by a NULL
pointer, and, since these are variadic functions, this pointer must be
cast (char *) NULL.?
This prevents crashes on 64-bit systems, where 0 is a 32-bit integer
and (char *) NULL is a 64-bit pointer.
